The benefits of servicing your commercial air conditioning systems cannot be overemphasized. Most business owners have had to spend more on energy bills and repair costs because of not servicing their commercial air conditioners regularly. But how often should you service your commercial air conditioning? Why do you need to service and maintain your commercial air conditioning? Find answers to these questions and more as you read on!

How often should you service your commercial air conditioner?

The average life expectancy of commercial air conditioners is about fifteen to twenty years. However, your commercial AC may not reach its maximum age if you do not service it regularly. Air conditioning systems used for most businesses should be serviced at least once a year. The timeframe for servicing commercial air conditioning systems depends on several factors.

One of the primary factors that may determine how often you should service your commercial air conditioner is the operating environment of your business. If you run a manufacturing industry business, your air conditioning system may need to be serviced at least twice a year (every six months).

If your business is close to an area with lots of construction activities, or it is located in a place prone to pollution, you may have to service your air conditioner every three months. It would be best if you also cleaned or changed your commercial air conditioner filters every six months.

Why you should service your commercial air conditioning systems

Your commercial AC has several components that work together to make your business environment comfortable. Hence it is critical to service the air conditioner system for optimal performance. Here are other reasons why you should service your commercial air conditioner:

• Reduced energy bills

Servicing your commercial air conditioner will help improve its efficiency and performance. It means you get a maximum cooling effect at a reduced runtime which helps to save energy bills.

• Lower Cost of Operation

Since you spend less on energy bills, it would translate to reduced operating costs. An optimally efficient air conditioner would need less energy to operate, which is great for your budget.

• Better Air Quality

The air outside your business environment is probably less polluted than the air inside your business space. A properly functional commercial air conditioner may help improve air quality inside your business. Routine maintenance on your air conditioner system may help reduce indoor air pollution.

• Fewer repairs

One of the perks of routine maintenance on your commercial AC unit is that you may be able to address small issues that may become expensive to repair if left unchecked. It is advisable to contact an experienced Air conditioner technician to carry out professional maintenance service on your commercial air conditioning system.

Keeping the warehouse of your business well-ventilated is paramount. The correct temperature in this place helps you to take care of your products, as well as maintain high levels of productivity and the health of your workers. Some studies show an average relationship of 2% decrement in work performance per degree °C when the temperature is above 25°C. 

In some industries, having control of temperature is critical. An example is the pharmaceutical industry, this sector loses approximately $35 billion annually due to products being stored and shipped at inappropriate temperatures. This effect is similar in businesses in the food and beverage, cosmetic or chemical industries.

For this reason, air conditioning is one of the key projects every property owner should keep into consideration. Taking advantage of the air conditioning warehouse sales is a great investment if you want to maintain a healthy airflow in the available space. Let’s review what you should consider when buying an air conditioner warehouse and which are the best options.

Which commercial air conditioner is best for a warehouse?

A commercial air conditioner can be used in commercial properties such as large office buildings or malls to small businesses such as coffee shops or convenience stores. The market offers you even more options for air conditioner systems.

You need to know the needs of your business to choose the correct aircon system. For example, it is important to know what is the maximum size that your aircon warehouse can have and in which part you would install it.

Rooftop air conditioning systems

Rooftop air conditioning systems for warehouses are often preferred. By placing their HVAC systems on the roof, businesses not only take advantage of unused space but also make it easy for HVAC technicians to conduct system maintenance without disrupting business operations.

The expert team of Ice Blast is qualified in the installation and repair of commercial refrigeration systems. We are highly experienced when it comes to finding innovative solutions for your business. Learn more here and enquire.

Improve the Indoor Air Quality

Places such as warehouses don’t have fresh air intakes. In addition, the industry generates a lot of heat and humidity, so they have to be kept on a reasonable scale.

Adding fresh air to a heating or cooling system accomplishes two primary Indoor Air Quality (IAQ) which controls building pressures and secondly, it increases IAQ by diluting polluted or stale indoor air.

If this topic is of interest to you, you can choose an air conditioner warehouse with an IAQ system. Usually, these systems have outside air enter through a roof or sidewall vent inlet that collects air from a clean outside location. The air is pulled into the system through a filter, into a duct connected to the return plenum.

What is the best month to buy an air conditioner for a warehouse?

Many warehouse managers pay attention to their HVAC systems when the temperature rises and summer begins. This can cause them to find themselves with higher prices or the best units sold out.

According to a Forbes study, especially for central air conditioning sales that require installation by HVAC professionals, the best time to make the call is during fall through spring. You’re more likely to save money with off-season air conditioner sales and by taking advantage of seasonal sales and deals during the off-season.

In any case, air conditioning costs depend on the type of unit, the size of the space to be cooled, and the existing ductwork. There are also less expensive options like water coolers, window units, or mini-splits.

Don’t worry! Regardless of the time of year, at Ice Blast you can find the best wrecks and expert installation service.

The importance of air conditioners in commercial properties like offices, cafes, shops, etc., cannot be overemphasized. Air conditioners create a conducive working environment for employees to function effectively. It also ensures the smooth running of heat-generating electronic devices like computers, printers, scanners, etc.

There are different air-conditioning systems that you can use in your offices. Each AC system has its unique healing and cooling properties. We shall highlight the various air conditioners that may be suitable for use in your office. Would you like to find out what they are? Then read on!

What air conditioner type is best for my office?

Your choice of air conditioner in your office depends on the size of your office, budget, quality, maintenance, etc. Here are the various types of air conditioners you can use in your office

Split Air Conditioning System

The cheapest Air-conditioning type suitable for use in the office is the single split. It is ideal for use in small office spaces. Split ACs can heat and cools specific areas in your office. They are also very convenient to install, making them a cost-effective heating or cooling solution for your offices.

Single split air-conditioning systems are energy efficient and may help reduce electricity consumption. Individual split systems are self-contained, which means that if one unit breaks down, it won’t affect the functionality of other units. The drawback of this AC system is that more external space is needed for installation. You will need to connect one indoor unit to an outdoor unit.

Multi-split AC

The multi-split AC system has some similarities with the single split system. It uses less external space, which allows you to connect up to nine indoor units using a single outdoor unit.

Its ability to save outdoor space makes it preferable for use in offices, shops, restaurants, etc. Multi-split systems do not limit you to having a particular indoor unit type. With multi-split systems, you can have both wall and ceiling mounted indoor units.

Cassette AC system

Cassette AC system is also a space saver when used in your office. Their cassette-like shapes make them ideal for installing on your office ceiling. They come with beautiful panels that can blend with different office decors.

Apart from their stylish appearance, they also have high performance. They do not require ducting and can be used for large and small office spaces. Cassette AC systems provide cool air to accommodate about ten to fifteen persons in an office.

Ducted AC system

With Ducted Air Conditioning, the heat pump system has an indoor unit and an outdoor unit. The outdoor AC unit usually doesn’t vary very much between different types of Air Conditioning Systems. However indoor units can have many different forms, and in this case it has a connection to ducts.

Normally these ducts get hidden behind a suspended ceiling as it may look ugly if they are not hidden. However, it is also not uncommon to find the ducts exposed and showing out in the open as a decorative part of certain eateries and kitchens going for an industrial look.

Ducted Air Conditioners perform very well and can have high energy efficiency. They work with a single indoor unit, so it is not necessary to install multiple units in different rooms. It is aesthetically pleasing to many when it is installed up out of the way in the ceiling and it doesn’t take up space on the wall.

Work productivity remains an utmost concern for several business owners. Many employees are required to be productive regardless of the working conditions.

However, research has shown that a worker’s productivity reflects the kind of working conditions they are subjected to.

While there are several ways to enhance work performance, having a good air conditioning system offers a good way to enhance workers’ productivity. A comfortable working environment is crucial to employee performance, and proper air conditioning helps provide such comfort.

The following are some of the ways air conditioning can improve work performance;

1. Enhances worker’s health

An employee can only be productive when they’re healthy. A functioning air conditioning system has several health benefits that enhance employee productivity. They include:

• Improves respiratory conditions: Airborne particles are common in the workplace and may likely cause respiratory illnesses. Similarly, gases and fumes from the outer surrounding may also enter the office apartment. A good air conditioning system helps circulate clean and fresh air by removing stale and heavy particle air.
• Faster metabolism: An air conditioning system helps reduce the office’s temperature to a level that promotes faster metabolism in employees.
• Reduces the pressure on the immune system: Germs spread faster in poorly air-conditioned rooms. An air condition unit provides the right temperature that mitigates the spread of germs.

2. Enhances worker’s comfortability

Several factors play a significant role in workers’ productivity. However, comfort in the workplace has remained an integral aspect of performance.

Research has shown that workers are more excited to work when comfortable. While there are numerous ways to improve employees’ comfort in the workplace, installing a functional air conditioning unit is very crucial.

Office temperatures have a strong connection to workers’ mood and productivity. For example, there is a difference between an office with a comfortable temperature of 74 Celsius to a stuffy 80 degrees.

A proper air conditioning unit goes a long way in enhancing employee comfortability and improving productivity.

3. Stable office temperature

An office environment with a stable temperature helps to maximize performance. Workers love a stable office temperature.

Coming to work each day to meet varying temperature levels can be quite unsettling. While there is a debate on the ideal work temperature, studies have shown that a temperature of 25 degrees Celsius is best for workers’ productivity.

An office apartment would need a good air conditioning system to keep temperature levels stable at the workplace.

4. Ideal humid temperatures

Aside from heat, humidity is another factor that unsettles many employees. Air conditioning systems with inbuilt humidifiers allow for humidity control.

Research shows that the ideal relative humidity of the workplace should be between 40-60%. Low humidity may cause itchy or dry skin and increase workers’ vulnerability to cold and infection, resulting in low work performance.

Workers perform best when they are relaxed, healthy, and stable. One of the best ways to enhance workers’ productivity is to ensure they are comfortable in their workplace.

With a proper air conditioning system, business owners and executives can improve the health and comfort of their workers, which helps to promote productivity.

Your air-conditioning system operates at a much higher capacity than during moderate or cold weather during hot weather. Hot weather increases your air conditioner’s workload and may affect its performance over time. It may also lead to increased energy consumption, so you may have to pay more about how hot weather may impact your air-conditioning.

Here are some of the impacts of hot weather on your air-conditioning system:

Additional strain on your air conditioner

As mentioned earlier, your air-conditioning system works more during hot weather. Since you may need a cooler indoor temperature during summer, it could cause your air conditioner to deteriorate faster. Over time, it may become more challenging for your AC to move the hot air inside your home to your outdoor surrounding.

Your air conditioner operates as a warm air exchanger by absorbing heat from inside your home and discharging the heat outside your home. The heat flow is from a high heat region to a low heat region.

It is expected that the hot air will flow outside, but it may be difficult for the hot air to be discharged outside during hot weather. Your AC will have to work harder to be able to remove the hot air outside as the outdoor temperature increases. However, the issue may be resolved if you have a good AC maintenance plan.

It is advisable to contact a professional air conditioner repair and maintenance expert to keep your AC in perfect condition to deal with the additional workload during summer.

Problems with your AC components

Like every other piece of equipment, continuous operation of your air conditioner at maximum capacity over time may affect the components inside the air conditioning system. It may be difficult for some of your air conditioner components to withstand the high workload during extremely hot temperatures.

The components responsible for providing the required voltage to your air conditioner’s engine may be the most affected. During extreme temperatures, your AC capacitor may wear out, and this may affect the functionality of your air conditioning system.

You can diagnose a faulty AC capacitor if you hear a clicking noise within the AC compartment. You should not hesitate to contact an AC repair technician if you notice this unusual clicking sound.

High Energy Bills

While hot weather may affect the efficiency of your AC over time, it may add a strain to your finances due to increased repair and maintenance costs. That’s not all. Since your AC is operating at a much higher capacity due to increased workload, it may have a toll on your energy consumption.

A higher energy consumption translates to an increase in energy bills. However, you may reduce your air conditioner’s energy consumption by ensuring your AC is properly maintained so less strain will be on the AC’s components when operating at optimal capacity.

You may feel that having an air conditioning system for your business may be unnecessary due to the cost of purchasing, installation, and maintenance. But is that true? In this post, you shall find various reasons why an air conditioner in your business shouldn’t be viewed as a luxury but a necessity because of its immense benefits.

Here are five reasons why you need air conditioning in your business:

Improved employee health

Air conditioning helps to improve air quality around your business environment by removing pathogens and dust particles. Inhaling contaminated air may cause your employees to report sick. When that happens, it may hurt your business productivity. Why not have an air conditioner installed in your business today to keep your employees’ healthy and ready for work?

Increased comfort for customers

Imagine trying to negotiate a deal with your customer in a stuffy or hot office. The outcome may not go as expected. But how about ensuring the customer is comfortable and enjoying the cooling effect from your air conditioner? There is a higher chance of getting a favourable deal from your customer. Great business deals are stuck where both parties are comfortable.

Comfort in this sense isn’t just about the contract terms but also about how conducive and comfortable is the business environment.

It enhances focus and increases employee productivity.

A business place where employees are constantly excusing themselves to get fresh air outside may cause them to lose focus on their tasks. Distractions caused by an unconducive working environment may hamper employee productivity. Contrary to the misconception that when employees are comfortable, they may feel sleepy and end up being unproductive.

In reality, employees perform better if they are comfortable with their job details and the working environment. You can improve employee productivity today by installing air conditioning in your business place.

Reduced Energy Cost

Do you know that using an air conditioner in your workplace can help you save energy costs? If you opt for fans or heaters, you may have to purchase and install several units to achieve a similar effect as an air conditioner. You may enjoy cooler or warmer air based on the temperature you desire with an air conditioner.

A single air conditioning system may effectively cool a wider business area than fans and heater. If you are thinking of saving energy costs in your business place, installing air conditioning may be a great way to achieve that.

Protecting your business equipment

Most equipment carrying out daily business operations requires cooler temperatures to operate effectively. Your computer systems, printers, photocopiers, servers, and other equipment produce heat while working. With proper air conditioning, this office equipment can function effectively. Air conditioning also reduces maintenance costs and the overall performance of your office equipment.

Heating, Ventilation, Air Conditioning, and Refrigeration (HVAC&R) is a significant cost to any home or business.  This is especially true when it comes to commercial buildings and offices, where HVAC systems account for up to 50% of the energy usage and costs!  

In today’s business-world, owners are trying to (and managers are expected to) do far more with far less.  That is, less money, less time, and less resources.  Business concepts like Return On Investment (ROI) and Value for Money (WFM) are more important now than ever before.

With such high costs involved and such a demand for cost-savings, how can we get smart with the HVAC&R systems in our businesses?  There are 2 key ways; Routine HVAC&R Maintenance and Steril-Aire Installation.

Commercial Maintenance

There are many options available to a business when it comes to saving money with a heating and cooling system.  However, it’s important to be aware that not all available options are equal, nor is there a one-size-fits-all solution.

It is a common misconception that a business will save money by reducing the frequency of their commercial HVAC services.  For example, reducing from monthly servicing as per Australian Standards down to say quarterly or less.  The short-term savings of decreased HVAC maintenance are far outweighed by the long-term implications and expenses, including but not limited to:

• Decreased efficiency of the heating and cooling equipment,
• Increased running cost of such equipment,
• Decreased compliance with acceptable Building Standards,
• Decreased compliance with tenancy agreement (where applicable),
• Decreased efficiency of other business equipment if not cooled correctly (e.g. IT equipment),
• Increased running costs of other business and mechanical equipment,
• Decreased lifespan of all equipment due to wearing out prematurely,
• Increased equipment replacement costs,
• Increased down time due to damaged or underperforming equipment,
• Decreased worker satisfaction and team morale due to such issues,
• Decreased productivity from people and equipment,
• Decreased HVAC system-related indoor air quality,
• Increased viral and bacterial spread in the workplace,
• Decreased compliance with health regulations,
• Increased number of sick days taken,
• Decreased health of employees in general, including poorer health outcomes,
• Increased incidence of chronic disease,
• Decreased compliance with Workplace Health and Safety requirements,
• Decreased customer satisfaction and repeat business,
• Decreased sales due to customer dissatisfaction and reduced productivity, and,
• Increased business risk due to all points listed above.

One of the most powerful solutions is to engage a commercial HVAC&R specialist to perform routine maintenance of all relevant equipment onsite.  This way, the maintenance is set-and-forget; you can rest easy knowing that one major area of your business is under control without requiring constant attention.

UVC Sterilizer

Another powerful solution to ensure commercial HVAC&R systems are clean and healthy is UVC light installation.  Again, the options available are certainly not all created equally.

The most powerful, effective, high quality, and evidence-supported UVC lamp on the market is Steril-Aire.  Steril-Aire was founded in 1994 and is a global leader in Indoor Air Quality (IAQ) improvement and energy savings when it comes to HVAC&R systems.

This cleaning and maintenance solution could save you thousands, with return on investment (ROI) typically seen within 2 years (often within just 1 year!).  The use of ultra-violet C (UVC) sterilisation in the Cairns Regional Council heating, ventilation, and air conditioning (HVAC) systems is a prime example.

Steri-Aire is a single-ended, very high output germicidal ultraviolet-C (UVC) light emitter that can be installed in new and existing HVAC&R systems.  It is designed to improve business operations and profits in countless ways, including but not limited to:

• Improved energy efficiency,
• Improved system operations,
• Improved indoor air quality,
• Improved human productivity,
• Improved mechanical productivity,
• Decreased energy costs by up to 15%,
• Decreased water usage,
• Decreased maintenance costs,
• Decreased need for AC chemical cleaning, and,
• Decreased sick-leave and down-time costs.

There are many UVC products on the market, but only Steri-Aire devices are engineered to work within HVAC systems in the presence of cold, moving air.  It has also been independently tested to deliver up to 6 times greater output compared to other ultraviolet devices.

As a UVC sterilizer suitable for use in food and refrigeration settings, Steri-Aire can help manage mould and bacterial growth with major implications.  This application improves the bottom line of such businesses in many ways, including but not limited to:

• Improved food safety,
• Improved quality,
• Increased production yields,
• Increased shelf-life,
• Decreased wastage, and,
• Decreased incidence of food poisoning.

How does Steril-Aire Work?

The C wavelength on the UV light spectrum attacks microbial DNA, destroys their cells, and prevents replication.  By preventing reproduction, the microorganisms are inactivated and become harmless.  The resulting matter simply washes away with the condensate (water) produced within the system.

Steri-Aire UVC light energy breaks down and inactivates biofilm, which otherwise causes significant HVAC&R operational issues and indoor air quality (IAQ) concerns.  Biofilm is a slimy, sticky matrix of microorganisms and matter that builds up on coils, drain trays, and anywhere else where moisture is present.

Biofilm can be made up of many different forms of bacteria (often antibiotic-resistant), mould, fungi, and debris.  It’s no wonder why it’s a major cause of health and operational issues in most HVAC&R systems.

The UVC emitter germicidal lamps also destroy viruses and bacteria that pass through an HVAC indoor unit.  If not destroyed, these recirculate and spread throughout the indoor environment.

The high energy output of the Steril-Aire UVC devices, combined with the recirculating air in a typical HVAC system, facilitates the deactivation of large volumes of airborne microorganisms.  This makes it an extremely powerful method of improving the health of both the HVAC system and people being exposed to it.

Where can you use Steril-Aire?

For these reasons, and many more, Steril-Aire UVC lamps are most suitable for use in, but not limited to, the following commercial and residential settings:

• Food processing,
• Agricultural product storage,
• Manufacturing warehouses,
• Research laboratories,
• Pharmaceutical production,
• Medical storage,
• Medical centres,
• Hospitals,
• Aged care facilities,
• Childcare centres,
• Schools and educational buildings,
• Airports,
• Shopping centres,
• Government facilities,
• Office blocks,
• Dirty work environments,
• Sites serviced infrequently and/or in an ad hoc fashion,
• Sites where access to unit, coil, and/or drainage is limited,
• Sites containing sick and/or vulnerable populations,
• Sites containing allergy suffers, including asthma, and,
• Any home or business where improved IAQ is desired.

As you can see, Steril-Aire is suitable in a wide range of settings for a wide range of applications in both homes and businesses.  It’s high output, specifically engineered UVC lamps enable significant improvements in health and cost savings.

Return on investment and value for money are 2 key concepts that every smart business owner understands and seeks out in the current commercial climate.  Routine HVAC&R maintenance and Steril-Aire represent investments that tick just about every box.

For a quote on commercial AC servicing and/or Sterile-Aire supply and installation, it is recommended to contact a commercial HVAC&R specialist.  Ice Blast is a wholesale provider of Steril-Aire devices that can work with you to find the most suitable solutions for your needs.

Would you be surprised to learn that aircon servicing can actually save you more money than you spend?  Well, read on to find out more.

Cost can vary significantly from one company to the next, one service type to the next, and is dependent on the number and type of air conditioning system/s you have.  There are many other factors involved that determine the cost of servicing air conditioning that we will explore here.

By paying more, are you getting a better service?  Not necessarily.  It’s more about finding the commercial air conditioning servicing arrangement that best suits your business requirements.

We’ll explore the cost of servicing commercial air conditioning in this article.  Hopefully this will help you weigh up the array of service options available and find the best solution for you.

Is AC servicing necessary?

Air conditioning servicing is designed to support heating and cooling systems in place and ensure they are operating correctly, now and into the future.  It is designed to help extend the functional life of the air conditioning units.  In turn, fully operational and well-maintained AC systems are designed to provide comfortable conditions for occupants within the building.

Maintenance is particularly important for commercial air conditioning.  Commercial AC is typically designed to function as a larger Heating, Ventilation, and Air Conditioning (HVAC) system.  HVAC systems support business operations, systems, equipment, and heavily impacts the health and wellness of all occupants.  Such occupants can include:

• Staff,
• Contractors,
• Visitors,
• Suppliers,
• Customers,
• Family members,
• Children,
• Vulnerable populations, and,
• Anyone who enters the indoor environment.

Adequate air conditioning servicing is required to help reduce the spread of germs in the workplace.  Furthermore, AC units can actually be a source of disease themselves if not properly maintained.

Condensate (moisture) within an air conditioner is a normal part of air conditioner operations.  Dust and matter also enter the unit as part of the standard flow of air.  This dark, moist, nutrient-rich environment within the AC creates the perfect home for bacteria, mould, fungi, and other organic matter to thrive.

Filters are designed to help filter out dust and other particles that otherwise serve as fuel for microorganisms and reduce matter build up on the internal heat exchanger coil.  However, regular internal maintenance is also required to effectively manage the air conditioning system.  Air blown out of an air conditioner is only as healthy as the internal environment of the unit.

HVAC systems impact the health of building occupants in many ways, including but not limited to:

• Temperature management,
• Humidity regulation,
• Moisture control,
• Air filtration,
• Fresh air provision/intake,
• Exhaust ventilation,
• Air purification,
• Pollutant removal,
• Ozone removal, and,
• Indoor air quality (IAQ) improvement.

What is done in AC Servicing?

It is a requirement of Australian Standards (3666.2.2011, 1851.6.1997, 2467.13.1997, HB32:1995) and the Workplace Health and Safety Act that commercial air conditioning equipment and plant be inspected on a monthly basis to maintain an acceptable commercial environment.

Australian Institute of Refrigeration, Air conditioning and Heating (AIRAH) also calls for monthly maintenance of commercial heating and cooling equipment.  Some aircon servicing tasks are recommended monthly (e,g. checking/clearing drains, checking/adjusting major components, etc), while a combination of other service tasks are prescribed at three, six, and 12 month intervals.

Some of the checks on an annual level service visit include but are not limited to:

• Full inspection of the AC equipment,
• Remove, clean and re-install filters where required,
• Check/clear condensate drain,
• Check/clear drain tray,
• Check/clear safety drain where required.
• Flush drains where required,
• Place condensate tablet/s in tray of main drain,
• Check for signs of oil or refrigerant leaks,
• Check refrigerant charge where required,
• Check for signs of animal/vermin damage,
• Check condition of evaporator coil,
• Check condition of condenser coil,
• Check belts,
• Tighten/realign belts where required,
• Check bearings,
• Check motors and mechanical components,
• Check pipework for damage to insulation,
• Check operation of reversing valve where required,
• Check electrical terminals,
• Tighten/adjust terminals where required,
• Check air flow,
• Check air temperatures,
• Check for fault codes,
• Check thermostat/sensors,
• Adjust/calibrate sensors where required,
• Check voltage reading,
• Check full load amps reading,
• Check general operation and condition of unit,
• Make minor adjustments where required,
• Report on and/or rectify any issues found, and,
• Complete life cycle assessment on equipment.

How much does AC service cost?

Commercial air conditioning service costs are often worked out by calculating the number of hours required over the year, times by the hourly labour rate, then divide it by the service frequency.

For Example:

• 36 hours of servicing required over the year,
• x $100 per hour,
• = $3,600,
• ÷ by 12 months of the year,
• = $300 per month.

To calculate the hours of servicing required, a good AC company will use Australian Standards to work out all the tasks required for all equipment over the year.  The hours and subsequent cost of servicing depends will depend on many factors, including but not limited to:

• Complexity of components,
• Access to equipment,
• Type of equipment,
• Size of units (physically and capacity),
• Nature of controls system,
• Skill level of technician/s required, and,
• Frequency of visits.

In a direct sense, commercial air conditioning servicing may be more expensive compared to home air conditioner servicing over the course of a year.  However, the indirect costs (or rather cost savings) make commercial AC servicing an overall positive return on investment (ROI)

What happens if AC has no service?

There are many benefits of air conditioning, IF the systems are maintained correctly.  If not, the list of possible issues is endless.

Failure to implement adequate commercial HVAC maintenance has a range of negative outcomes.  For example, lack of routine aircon servicing can have extensive impact on business equipment preservation, including but not limited to:

• Increased operating costs as equipment works harder when not cooled sufficiently,
• Decreased efficiency of operational equipment,
• Decreased lifespan of equipment due to working harder and burning out quicker,
• Increased power costs,
• Increased equipment replacement costs,
• Increased unreliability of equipment,
• Increased down time due to failing, faulty, or completely broken equipment,
• Decreased satisfaction of workers due to issues with equipment,
• Decreased production and output,
• Decreased sales due to time spent dealing with equipment, rather than sales activities, and,
• Increased risk to business operations.

As you can see, lack of air conditioning servicing creates costs, reduces returns, and introduces unnecessary risk into business operations.  The impact of aircon serving on business equipment is just one example!

The health of building occupants is a major focus of air conditioning servicing.  As discussed, lack of commercial aircon servicing results in negative staff and customer outcomes, including but not limited to:

• Poor Indoor Air Quality (IAQ),
• Increased illness and disease,
• Poorer health outcomes,
• Increased staff sick days,
• Decreased productivity,
• Decreased sales,
• Decreased staff satisfaction,
• Negative customer experiences, and,
• Decreased repeat business.

Routine scheduled maintenance is key to ensuring HVAC equipment is managed in the most appropriate way.  Failure to maintain commercial air conditioning can have a wide range of compliance implications, including but not limited to:

• Failure to comply with Australian Standards,
• Failure to comply with Building Standards,
• Failure to comply with Workplace Health and Safety Requirements,
• Failure to comply with Health Regulations,
• Failure to comply with Lease Agreement (where applicable), and
• Failure to provide an acceptable commercial environment.

As you can see, there is certainly a direct cost involved in implementing and continuing commercial air conditioning servicing.  However, the indirect costs of failing to implement such critical maintenance into a business far outweigh the direct costs involved.

Hopefully this article helps highlight the importance of aircon servicing and benefits to a business far beyond the obvious costs involved.  For an obligation-free air conditioning maintenance proposal, please do not hesitate to contact our commercial HVAC servicing team today.

If we tell you that you can save money and take care of the environment while having an air conditioner at home, would you believe us? Well, the truth is that it is possible, if you choose an energy-efficient air conditioner.

You can find energy-efficient appliances including air conditioners in almost all their forms. It may be a higher investment at the beginning compared to a regular air conditioner, however the long-term savings can make up for it.

What is energy efficiency?

Energy efficiency refers to the optimization of resources to achieve a goal. This means using less energy than normal for an appliance to work but achieving the same results. Thus, energy efficiency includes all those actions that aim to save energy without representing an impact on your qualify of life.

Using energy efficiently also means not using it in unnecessary ways and doing what you require with the minimum possible consumption. To achieve this, it is essential to explore new technologies and systems that save energy to achieve a sustainable life.

The efficient use of energy contributes to protecting natural resources and reducing environmental impact. For this reason, it is not only necessary to have efficient technologies, but also responsible for consumers like you.

How to measure energy efficiency?

To make sure that you are truly increasing energy efficiency throughout your home, optimizing the performance of your appliances, and achieving your objectives it is essential to measure energy consumption.

The easiest way to measure your energy savings is through the annual cost of electricity. If your power bill is small/smaller, it means that the energy efficiency in your home is high.

The importance of energy-efficiency

The energy efficiency of the air conditioning is measured based on the amount of energy generated for each kW of energy consumption. The higher the energy generated for each kW spent, the more efficient your system will be.

Furthermore, all appliances have a label that explains their energy efficiency. This efficiency is measured with different letters, from “A” to “G”, with “A” being the most efficient and “F” and “G” the least efficient.

Remember that energy efficiency is one of the main saving factors that must be taken into consideration if you want to ensure optimal use of your air conditioning.

How to choose an energy-efficient air conditioner?

To choose an energy-efficient air conditioner you need to think about your own needs but also identify the models that consume less energy.

Energy

For you to make sure to invest in an air conditioner that doesn’t consume too much energy you need to look at its label, which can range from A +++ to B depending on kW rating.

You should have a higher budget to install your air conditioner because cheaper alternatives often offer low performance and high electricity consumption.

The EER rate

To measure the true efficiency of an air conditioner, it is essential to compare the EER rate or Energy Efficiency Rating of each model. This refers to the amount of electricity needed to obtain a defined cooling capacity.

To sum it up, the more energy it takes to reach the desired objective, the more power the device uses.

Energy consumption

Energy consumption is an excellent indicator to anticipate the impact of air conditioning on the annual electricity bill. It is measured in kWh and you can simply compare the information for each model to make an informed decision.

Sound of the air conditioning system

The sound of an air conditioner varies between 45 and 60 dB. What you should do to not have any problems with your air conditioner is looking for the ones with the lower levels.

The good news is that energy-efficient air conditioners possess high-level technology with hardly any sound.

How to optimize your energy-efficient air conditioner

Look at the label

An energy-efficient air conditioner can save up to 60% more than a conventional one. For this reason, as we stated before, there are appliances that are cheaper but they are not energy-savers but in the long run. You will pay for them eventually!

Always keep your appliance in good condition

Performing regular maintenance on your air conditioner is key to extending its lifespan. Also, avoiding dirty aircon filters is essential for the proper functioning of your air conditioner. It also keeps away all the mould and bacteria that may affect your health and the health of your family.

Having habits to minimize the heat in your home

The best tip that we can give you to minimize the heat in your house is to ventilate your home at night, so this will cool down the environment in the morning. For the rest of the day, it is better to keep the windows closed so this will avoid increasing the temperature of your home.

Keep in mind that if you are going to leave the house, you should turn off your air conditioner and turn it on when you come back. In this way you will be saving energy and money.

Monitor and regulate the temperature

The main reason to buy an air conditioner is to be comfortable at home. However, it is a great idea to make your air conditioner work as efficiently as possible. For this reason, we recommend you set your aircon at 22-24ºC. For each degree you adjust beyond that, you can increase the cost of your bill up to 10%.

Help yourself with other elements

When the heat is not suffocating, having ceiling or portable fans installed can help you save energy and money as you will not be using the air conditioner as frequently.

Even when you do have the aircon on, fans can further enhance the cooling effect and reduce demand on the air conditioner. This leads to further energy savings and comfort.

Get advice from a specialists

It is not the same to cool down a small place vs a large place or design an air conditioner system for a room vs a whole house with several rooms. There are many other factors that effects which size of air conditioner you need to have greater energy-efficiency. For this reason, it is better to get advice from a specialist.

Remember that being more efficient does not mean giving up a degree of well-being and quality of life. It is simply a matter of adopting a series of responsible habits, measures, and investments at a technological and decision-making level.

When you invest in a new air conditioner, it’s common to be focused on the cost of the system upfront, the energy efficiency of the aircon, and when can it be installed.  Once these initial concerns are resolved, it’s time to start thinking about the lifespan of your air conditioning system.

There are many different factors that impact how long an air conditioner unit will last.  These includes but are not limited to installation quality, how your use the system, strategies in place to assist the aircon, type of maintenance carried out, the nature of repairs, and paperwork in place from start to finish.

Fortunately, there are many things you can do to ensure your new air conditioning system reaches its full potential.  For this reason, the article will go through 7 key areas worth focusing on.  For each area, we will narrow-down information into 4 main points that can make or break your aircon’s expected lifespan.

Installation

Before you even install your air conditioner, there are things that can be done to ensure the air conditioning equipment reaches its full potential and lifespan.

Design/Size

Design

Before installing any air conditioner units, you want to ensure they form part of the most suitable, well designed AC system for any given application.  For a floor, ceiling or wall mounted split system, position and associated components installed are vital.  For a ducted system, layout and quality materials can seriously impact the longevity of your air conditioning system.

For a ducted AC system, with a network of ductwork in the ceiling space, it’s important that the system is designed and installed by an experienced ducted aircon installer.  Many factors impact the ongoing efficiency of the system, including zoning type and layout, ductwork size and insulation rating, supply/return air outlet size and number, and wall controller/thermostat/sensor location.

Poor design, inferior materials, and poor workmanship will cause the system to struggle and wear out faster as a result.  It will also cause endless issues and excessive power usage along the way.  This is true for ALL air conditioning unit types.

As a result of sub-standard design, you will need replace the air conditioning system sooner than you would with a higher quality and suitably designed system.  For the sake of a few dollars saved upfront, you can easily end up paying far more in the long run.

Size

Before installing an air conditioner, it’s important to ensure that it is a suitable size for the area it will serve.  This refers to the capacity, typically measured in kilowatts (kW).  Just like Goldilocks and her run in with the Three Bears, an aircon can be too big, too small, or just right.

If you put in an air conditioner that is too big, it will cycle on and off more frequently as it tends to overshoot the desired temperature, detect this, stop, wait for temperature to go the other way, and then blast out hot/cold air again.  This constant on/off and short cycling damages the internals of the AC units as they are designed for run for longer periods of time and complete certain cycles.  This means the internal components will fail earlier than designed.

If you put in an air conditioner that is too small, it will tend to have to run for longer and complete more cycles before it turns off.  It may not even reach the desired set point, meaning it continues to run non-stop!  This will cause the internal components to wear out much sooner as they never get a break, except when the system is not in use.  This is why server room aircons (running 24/7) only come with a 1-year manufacturer’s warranty, rather than a standard 5-year warranty.

If you are not sure what design and kW rating air conditioner you need, it’s best to chat to an experience AC installer about what sized air conditioning system would be best for a certain space.  There are many factors to consider, such as the size of the area (m2), heat load/activities conducted indoors, insulation/materials used in the building, and building/window/door orientation.

Unit Location

Indoor Unit

Before getting air conditioning units installed, you want to make sure they are going in the right location.  Otherwise, the system can be compromised and lifespan reduced as a result.

For a wall split indoor unit, it’s best for the unit to be installed:

1. Back-to-back with the outdoor unit. Efficiency of the system decreases as pipework length increases, so you want to prevent excessive pipe run.  Decreased efficiency means increased strain on the whole air conditioning system.
2. Centrally near the middle of the room without obstruction. Supporting even airflow and temperature dispersions with a central, obstacle free location reduces workload.  This preserves the AC system as whole and helps extend its feasible running time.
3. Up high up on the wall close to the ceiling (~2.4-3.0m off the ground). Obviously if there are cathedral ceilings or similar, then the indoor unit should be as high as reasonably practical.  This recommendation is designed to complement the natural phenomenon of hot air rising and minimise demand on the aircon.  It also helps support optimal performance and allow reasonable access for routine maintenance.

There are also important factors to consider when installing a ducted air conditioning system.  Ducted AC units need to be installed in a position that supports ongoing efficiency, maintenance, and repairs.

For a ducted indoor unit, it’s best for the unit to be installed:

1. Close to the manhole. This allows ease of access to the unit to support routine maintenance.
2. Suitable distance away from the ceiling and/or beams in the roof. This also allows suitable access for a professional service, chemical coil clean, and/or repairs.
3. Suitable proximity to supply and return air ductwork. This ensures efficiency is not lost through excessive flexible duct runs.

The ducted return air grille/filter that allows air back into the indoor unit is also important to consider.  This critical air re-entry point must be visible and accessible in a well-ventilated part of the home or office.  Otherwise, it can easily get blocked, increase pressure on the system, and lead to AC equipment failure.

Outdoor Unit

Just like with the indoor unit, before getting your new air conditioner installed, you want to make sure the outdoor unit is going in the best location.  Failure to do so can result in reduced AC lifespan in many ways.

The outdoor unit (i.e. condenser) is the powerhouse of an air conditioning system.  The harder it has to work, the less efficient the whole system is.  Running the air conditioner in a lower efficiency state causes the system to wear out faster.

To prevent this issue, it is recommended to install the outdoor unit a well-ventilated, cool, dark/shaded place.  This is because heat and sunlight can increase the unit workload as well as cause certain components to wear out faster.  Condenser pipework insulation is just one example of a UV-sensitive aircon component.

It’s also recommended to install the unit down on the ground, or in an easily accessible location, as opposed to a roof top or similar.  Not only does this help reduce sun and heat exposure, but it also supports routine inspection and servicing as the unit is then in a suitably accessible location.

Wherever the outdoor unit is installed, it’s important for it be level, clear from obstruction, and suitably secured.  If not level, the unit cannot work property and components wear out faster.  If not clear, airflow is reduced, causing components to overheat and fail prematurely.  If not secure, opportunist vandals or clumsy passers-by can damage the unit with a range of life-altering consequences.

Pipework

To ensure your air conditioner reaches its full potential, it’s important to ensure the correct refrigeration pipework is used in conjunction with the unit install.  Specifically designed pipework improves AC operating efficiency and prevents a range of issues.

Pipework used should be purposed for aircon installs; pre-insulated, UV-rated, annealed copper pair coil.  It should also be of the correct size for any given air conditioner and suitable length as per AC manufacturer specifications.

1. The insulation component reduces sweating of pipes.  This is important as water is never a good thing to have around an electrical device such as an air conditioner unit.
2. UV-Rated. The UV protection component reduces degradation in the face of UV light.  Unrated/inferior pipe insulation can breakdown and reduce system efficiency in as little as a few years.
3. Correct Size. Undersized pipe will prevent the system from operating at is maximum potential, meaning the system can struggle to adequately heat or cool a given indoor area.  Oversized pipe can cause serious compressor damage and premature equipment failure.
4. Correct Length. AC system efficiency increases as pipework length decreases, to a certain point.  While it is recommended to keep pipework length as short as possible, there will still be a minimum length required depending on the unit size and manufacturer instructions.  Incorrect length can also cause noise and/or vibration issues, which negatively affects aircon lifespan.

Drainage

Drainage may not immediately come to mind when considering how to extend the life of your air conditioner units.  However, it can certainly play a significant part in preventing unnecessary and life-reducing damage.

AC units produce condensate (i.e. water) during normal operation.  That water is collected in internal drip trays and drained away as required.  If your aircon is leaking water where it shouldn’t, it’s a big problem.

Excess water can promote micro-organism, fungi, and bacterial growth within an aircon unit.  This can cause mould and matter to build up on the coil, fan scroll, filters, and other AC components.  This reduces airflow and increases workload of an air conditioning system, impacting its expected lifespan if not resolved in a timely manner.

Failure to install a drip or safety tray, or suitable drainage, means that water may not be collected at the indoor unit and/or suitably drained away.  This can result in water overflowing onto AC electrical components.  As we all know, water and electrical do not mix.  Modern-day aircons are heavily electrically based, so water can cause significant damage to components such as printed circuit boards, capacitors, controls, etc.

Water can also damage structural or supportive components of the air conditioning system.  For example, water can compromise the structural integrity of the wall, floor, or ceiling below the unit.  As a result, the aircon may become unlevel or fall completely.  Unlevel units wear out faster or may fail to operate correctly at all.  Meanwhile, a complete fall could see the end of that particular AC unit.

Usage

Once your air conditioner is installed, there are many ways you can preserve the equipment and extend the lifespan of the system as a whole.

Controller/Temperature Sensors

Heat Load

Usage of an AC controller and temperature sensors can make or break the lifespan of any air conditioning system.  Incorrect usage can prevent correct system operation, increase workload, and waste power.  On the other hand, correct usage can extend lifespan and save you significant money in the process.

The air conditioner controller can also double as a temperature-sensing point.  This is often the case for entry-level ducted systems.  An increase in heat load near a temperature sensing component of the AC system will result in excessive cooling and subsequent workload for the AC system.

Once correctly installed, the area around sensors and temperature-sensing wall controllers must be considered.  It is recommended to avoid placing anything producing excessive heat in close proximity.  This includes common home devices such as washers, computers, TV screens, phone chargers, etc.  Direct sunlight must also be monitored and managed.

Set Point

Once the area around the temperature-sensing point is managed, the next consideration should be the temperature set point.  Minimising excessive usage of the air conditioner helps with preservation and system longevity.

Standard home air conditioners are designed to run at full capacity or idle.  They continue to work at full capacity until they detect that a given set point is reached.  At this point, they can then ramp down and reduce demand on the air conditioning system as a whole.

It is recommended to set the air conditioner to a temperature as close to the outdoor temperature as possible.  Some change is obviously expected, otherwise why would you use the AC, but every degree counts.  Not only is the system running life extended as a result, but aircon running costs are also reduced by 10% for every degree the set point is set closer to the ambient temperature.

Settings

Mode

The modes selected when running an air conditioner can reduce or enhance the expected lifespan of that system.  It is one of simplest ways to extend the life of your air conditioning units.

It is recommended to avoid Auto mode most if not all of the time.  Auto mode causes the aircon to automatically switch between Cool and Heat modes with the aim of steadily maintain a given set point.  This is an inefficient use of the AC system which unnecessary causes it to wear out faster.  Heat mode or Cool mode is recommended to be used instead.

There are other modes that can help enhance your air conditioner and its lifespan.  Dry mode increases the amount of air passing through the indoor unit, designed to remove moisture from the air rather than cooling it.  This this a more efficient mode that reduces power usage and demand on the system.

Fan mode is another more efficient mode available to preserve your air conditioner.  It allows air movement without inherent temperature adjustment or dehumidification.  It is one of the best modes available for extending the life of your air conditioner units.

Many aircons also have a Sleep mode or Night mode which can help extend the life of both you and your air conditioning system.  Sleep/Night mode increases temperature gradually by a few degrees, 0.5 – 1 degree at a time, to reduce demand on the aircon units without impacting your sleep.

Fan speed

Fan speed has a surprising impact on air conditioner energy efficiency and therefore system lifespan.  Fan speed refers to the speed of air travelling through the indoor unit, i.e. over the internal heat exchanger coil and subsequently blown out into the room/s.

Using high fan speed is recommended to rapidly and efficiency cool down a given indoor area.  This is the recommended way to bring up or down the temperature indoors to support your air conditioner and prevent unnecessary strain.  Once the desired comfort level is reached, fan speed can then be adjusted down to maintain the temperature.

Overnight, low fan speed it recommended as temperature maintenance is often the goal and the outdoor temperature often decreases significantly.  If it is a particularly humid day, and/or moisture removal is the primary goal, then low fan speed is also recommended for use.  This allows more time for the indoor unit to remove moisture from the air before it leaves the unit and enters the indoor environment.

Timers/Reminders

Timers and reminders are handy to have in an air conditioner unit as they help you manage its usage and extend its life.  Not all aircons come with timers, so it’s worth ensuring your chosen system has one before making the final purchase and installation.

Timers can be basic, push-button operated, controllable over Wi-Fi, or even integrated into a complete home automation system (e.g. Google Nest).  The set and forget type timers may be the most beneficial, with life being so busy these days that few of us have time to stop and think about the aircon schedule on a daily basis.

Reminders also come in various forms, from basic “filter check/wash required” reminders through to “time for professional service” reminders.  These help to maintain the system overall and keep it in good working order.  The key is to actually action the task prompted; there is no point having a filter check/wash reminder come up if you just clear it without touching the filter!

Once installed and familiar with, the next step is to actually use them.  Timers can help manage demand on AC units at key times, such as when sleeping or out of the house.  As indoor climate requirements change, so should use of the air conditioner system to match.  By doing this, the system is preserved and life extended.

In a commercial setting, timers and reminders can contribute to significant life extension of the heating, ventilation, and air conditioning (HVAC) system.  Timers can be used to switch off units out of business hours, while reminders can prevent AC system neglect and assist with routine HVAC maintenance.  These benefits can significantly extend the life of any commercial system.

Additional Features

Timers and reminders aside, new air conditioning units come with a range additional features; some designed for convenience, some designed to enhance performance, and some designed to protect the aircon.  Better yet, some features can provide a combination of these benefits.

Control over Wi-Fi, typically via a smart phone App, is one of those features that has many benefits.  Convenience aside, being able to check and control an AC system remotely can support you in optimal running of the system.  For example, you can pre-cool the home gradually before you get home, rather than overloading the AC when you walk in the door on a hot day.  Similarly, you can check in on the teenage kids at home on school holidays and ensure they are not demanding excessive cooling or heating from the air conditioning system.

Many modern-day air conditioner units also have an Auto or Self Clean function inbuilt.  This function typically involves drying out the inside of an aircon unit, which preserves the internal components in many ways.  Moisture management reduces the growth of mould, mildew, fungi, and other unwanted microorganisms.  It also reduces rust and corrosion that would otherwise damage key components such as the heat exchange coil.

Assisting

Air conditioning units can be preserved by considering their place in the home as a whole, rather than in isolation.  There are many cost-effective methods of supporting the air conditioning system in place and extending its lifespan as a result.

Building

Air conditioning systems are best supported when used in a building environment that holds the hot or cold climate produced.  Insulation and window treatments are two key factors that have a significant impact on indoor temperature retention.

Insulation can be present in the ceiling, walls, floor, or combination of these locations within a building.  The impact of insulation is significant, with an insulated roof space saving you up to 50% on your home heating bill!  This saving shows just how much the demand on the AC system can be reduced.

Window treatments come in all shapes and forms, including blinds, curtains, shutters, tinting, or a combination of these.  Windows can allow significant heat to enter and leave an indoor space, and an imposed barrier can dramatically reduce any unwanted exchange. As a result, the air conditioning system doesn’t have to work as hard or for as long to achieve desired comfort level indoors.

Fans

Many properties have air conditioning installed without fans, thinking that fans are not required when aircon is in place.  However, this couldn’t be further from the truth.  The reality is that fans are needed, especially in hotter climates, to assist and help preserve air conditioner units.  They are in fact one of the cheapest ways to extend the life your aircon.  If not already installed, it would be well worth contacting a local electrician today.

Fans help to circulate air in a given space.  While they may not inherently change the temperature of the air, they help people in the space feel cooler due to the cooling effect produced.  As a result, demand on the AC is reduced as a higher set point can be comfortable with the presence of air movement.

Whirlybirds and other roof-mounted exhaust fans can also assist your air conditioner units in a different way.  These out-of-sight fans are designed to extract heat at the top of the house, lowering the temperature in the ceiling space.  As a result, the rooms below the ceiling space (i.e. indoor space) will automatically be cooler.  This will subsequently reduce demand on the air conditioner, as the rooms are already closer to the desired temperature.

Heat Load

Heat or cooling load refers to the amount of temperature adjustment required to maintain a given temperature set point.  The higher the heat load, the higher the demand on the air conditioner.  Therefore, it is recommended to manage heat load in order to extend the lifespan of air conditioning equipment.

Using heat-producing devices when an aircon is already under significant pressure should be avoided wherever possible.  For example, cooking sausages on the outdoor BBQ on a hot summer evening, rather than in the kitchen, helps to reduce the indoor heat load and subsequent demand on the AC system.

Running clothes and/or dish washers in the morning before the weather heats up is another way to assist your air conditioner.  Further methods include turning off lights when not needed, especially non-LED ones, and putting the extraction fan on when showering/bathing.

By reducing heat load indoors, especially when the AC is working at is max, you can reduce workload required from the device.  This prevents the air conditioner from being maxed out and protects the internal components.  As a result, you can expect to enjoy the aircon in your life for many more years.

Surrounding Area

The area around an air conditioner unit is just as important as use of the device itself.  A clear, well-ventilated space around all units is required to ensure an aircon reaches its expected age.  This can be difficult as standard house block sizes are decreasing and storage space is becoming limited.

The minimum clearance zone around an outdoor condensing unit is typically 300mm, with 1000mm required in front of the unit.  The area between the back of the unit and a wall may be slightly less but must still comply with manufacturer install recommendations.  Failure to do this causes reduced airflow and operating efficiency.  This can see an air con system over-worked, over-heated, and all over before its time.

Not only can items around the condenser impact the unit, but it can also invite unwanted flora and fauna damage.  While certain greenery can protect your aircon, like a shady tree over the unit, it can also harm it if neglected and allowed to grow into the unit itself.  Furthermore, animals feeding on or living in the garden can interact with the air con unit in several life-shortening or even life-ending ways (unfortunately for both parties).

DIY AC Servicing

One of the most effective ways of extending the life of your air conditioner units is servicing them.  Just like your car, your aircon requires a minimum amount of maintenance to get it through an expected lifespan.

Frequency

DIY maintenance starts with regular filter checking, every few weeks, and washing when dirty.  It’s also recommended to check them after dirt or dust generating activities, such as spring cleaning, renovating or moving furniture.  More on filters later.

Aside from filter washing, there are many other simple aircon maintenance tasks that should be carried out routinely.  These tasks are designed to keep your air conditioning system working as designed, which helps it reach or even exceed predicted lifespan.

In a commercial setting, routine HVAC servicing is recommended monthly as Australian Standards.  Home air conditioners could also benefit from monthly maintenance, however every four to twelve months is typically sufficient.

The basic tests, checks, and cleaning recommended to maintain your own air conditioner has many benefits.  In relation to life extension, DIY aircon servicing allow for minor issues to be detected and resolved before they cause major damage.  It also supports optimal AC function and efficiency, which helps preserve major internal components.

Filter Maintenance

Filter maintenance is the number one service task you can do yourself to protect and preserve your air conditioning system.  However, there are more to filters than you may think.

Type

Firstly, it’s important to ensure the correct filter type is used with your AC system.  Types to consider, particularly for a commercial HVAC system, include manufacturer-specific, full/half ceiling tile panel, pleated, pocket, v-form, HEPA, or carbon.

The next consideration is the media type; washable or disposable.  Factors such as access, water availability (for washing), and finances (for purchasing disposable ones) impact which type is most suitable to support your particular aircon system.

Next point to consider is media/filter thickness.  There are clear Australian Standards for suitable air filter design and use in Australia depending on unit type and application.  To ensure correct AC operation, the filters should let air through to the indoor unit but be thick enough to suitably filter the air.

Clean/Replace

Filter cleaning is one of the most effective ways to maintain your air conditioner and ensure a long and healthy life.   Dirty filters increase air conditioner workload by 15% as evidenced by power draw.

Dirty or damaged filters prevent dirt, dust, dander, and other types of matter from being filtered property.  These can reach and/or build up in the indoor unit, which impacts aircons in many ways.  It promotes the build-up of dust, mould, mildew, fungi, and other microorganisms that reduces heat exchange on the evaporator coil, increasing strain on the system.  It also spreads dirty air, which is not only bad for your health but also for the health of your aircon system.

While it is a far less common issue, it is worth noting that filters can actually be washed too much.  This is more commonly seen with commercial HVAC systems, where business owners may insist on monthly filter washing even when a system is hardly used.  The media wears out over time, especially with washing.  This may not be a life-impacting issue for your aircon system UNLESS you fail to replace the filter when required, which may be sooner than expected with over-washing.

When a filter has worn out, it’s important to replace it or at least the filter media.  You can tell that a filter needs to be replaced when it is wearing thin in parts and/or light is more visible when you hold it up to a light source.  Failure to replace a relatively inexpensive part can see major aircon repair expense due to component damage, failure, or complete AC system failure.  An experienced HVAC technician can help you decide when filter replacement is due, as it can be a fine line between premature and overdue replacement.

Water/Cleaning

We all know that water and electricity do not mix.  The same can be said of electrically based devices such as air conditioners.  Water damage to AC components such as capacitors, PC boards, and motors can have life-shortening or even life-ending consequences for the system.  It can also cause corrosion and rust.

It’s not as simple as you may think, as some water is unavoidable when it comes to aircons.  Condensation (water) is produced as a normal part of refrigeration cycle.  It’s just a matter of managing the presence and use of water in order to maintain the air conditioning system.

As with filters, certain components of your AC system require inspection and cleaning when dirty.  For an indoor unit this includes the drain pipe/tray, fascia/covers, air inlets/outlets, fan barrel/scroll, and evaporator coil.  For an outdoor unit this can also include the drain, covers, coil, and area immediately around the unit.

Failure to keep these components clean can result in reduced heat transfer, reduce airflow, and reduce efficiency of air conditioner units, which shortens their life.  In the drains, all manner of blockages can occur, including algae, mould, sludge, insects, and even materials such as insulation.  To clean the various components, it’s recommended to use as little water as possible and the correct equipment for the job.

You also required complete knowledge of the electrical components (both directly and indirectly) involved in the area being cleaned to avoid harm to you and the air conditioner.  If you are not 100% sure, it may pay to call in a professional aircon service technician for such work, to avoid damage to the AC system you are looking to preserve, as well as yourself!  They also carry special chemicals and equipment designed to not only clean the system but slow future growth of mould and algae.

Visual Checking

Visual checking is one of the safest ways to maintain and extend the life of your air conditioner units.  It allows for issues to be detected while minimising the risk of physically harm.  Just take extra care if need to use a ladder or similar to access the aircon units.

When looking over the air conditioner, look at all visible parts of the system.  It is recommended to look for exposed electrical components, cracked insulation, water droplets or leaking in abnormal places, smoke or dust coming from the units, any signs of vibration or movement, and wearing/degradation in general.  You can also listen out for any abnormal noises, including banging, whistling, humming, squealing, gurgling, buzzing, rattling, etc.

It is recommended not to insert any foreign objects into the air conditioner while checking it.  This includes torches, sticks, screw drivers, brushes, and especially fingers.  Otherwise, damage can occur to AC components, the whole aircon system, the item you are inserting, yourself, and/or those around you.  Air conditioner damage can be as minor as a scratch or as major as complete system failure.

Professional HVAC Maintenance

While you can carry out a certain degree of maintenance yourself, there are some tasks that are best left to the experts.  It also pays to invest in a professional air conditioning service on a routine basis to help extend the life of your air conditioning system.

Frequency

If DIY maintenance is routinely carried out on your air conditioner, professional maintenance is typically not required as frequently as if no home servicing has been conducted.  This home aircon servicing includes frequent filter maintenance, visual checking, basic cleaning, etc., as discussed.  However, it certainly doesn’t hurt to call in the experts to help maintain and extend the life of your aircon, and it is actually recommended to be done on a periodic basis.

Home air conditioners are recommended to receive professional maintenance every year at a minimum, and even every 4-6 months in certain situations.  Commercial air conditioners are recommended to receive monthly maintenance as per Australian Standards.   For anything less, it is recommended to arrange a formal inspection and proposal from a good commercial HVAC service company.

Even if the heating, ventilation, and air conditioning (HVAC) systems are seemly working OK, there can be hidden issues that impact unit operation and cause the equipment to wear out faster.  A professional can test technical components and resolve issues before they start to reduce air conditioner lifespan.  A primary example is testing of capacitor tolerance and replacing these minor parts before they damage the associated motor and system as a whole.

Service Level

Extending the life of your air conditioner not only involves maintenance, but also the correct type of servicing.  There are many different AC service types that can be booked, from minor checking through to major pull apart and deep chemical cleaning.  It’s recommended to arrange the highest level required to suitably maintain your aircon, otherwise you may just be wasting your time and money as well as reduce AC lifespan.

Ideally, the aircon service technician you book has the ability to upgrade the service level while onsite.  For example, start with a minor/standard AC service with the potential to add on indoor unit chemical cleaning if mould is found deep within the unit.  Similarly, if insulation on the outdoor pipework is cracked or UV affected, it is recommended to patch it at that time or follow up another time at a suitable add-on price.

While some professional attention is better than none, failure to fully maintain your system will severely shorten its expected lifespan.  If you are going to all the effort of arranging an air conditioning technician, it pays to get the complete service done at that time.  You can easily save the extra money spent with the extra life given to your air conditioning system.

Technician Type

There is a lot of choice when it comes to air conditioning service technicians.  Many air conditioning and electrical companies promote AC servicing, although their specialties and expertise can be worlds apart.

To get the most out of your professional AC service, it is recommended to book a technician with a valid ARCTICK licence.  This Refrigerant Handling Licence ensures that the tech can complete all tasks in a routine service, rather than just the electrical ones.  Handling AC gas/refrigerant is an offence unless you have this specific licence in Australia.

It is also recommended to book a technician with specialized air conditioning training and qualifications.  A heating, ventilation, and air conditioning (HVAC) contractor is technically a “Refrigeration Mechanic”.  This type of contractor is specialised in the refrigeration cycle, which is what all air conditioners are based on.  To help extend the life of your air conditioning units, it’s important to book the contractor that has been specially trained to care for them.

Recommendations

Once you have booked the correct technician at the recommended frequency to carry out the most suitable level of AC servicing, it’s then important to consider and action as many of their recommendations as possible.  Otherwise, you may not get the full life out of your air conditioner units.

Common recommendations worth actioning include set point for your system, filter cleaning frequency for your environment, chemical cleaning for your degree of mould/matter build up, clearance around the AC units for your unit location, and minor repairs for the state of your aircon.

Reputable air conditioning companies and technicians genuinely want to help you get the most out of your air conditioner.  Their reputation is also on the line if the units pack up and fail sooner than expected.  Therefore, a good tech will recommend ways to preserve the AC equipment.  However, if recommendations are ignored, they can not be held responsible for the shortened lifespan of your air conditioner units.

Repairs

Air conditioner repairs can vary from minor to major.  Some are critical to system operation, while some may not impact the lifespan of an air conditioning system.

DIY vs Professional

Just like with air conditioning serving, there are tasks that you can do yourself and some that are best left to the experts.  You may be wondering what to do if air conditioner is broken.  Do you tackle it yourself or call in a professional?

First, the issue needs to be diagnosed correctly.  Just like Dr-google for diagnosing a medical condition, home air conditioner owners can feel like an air conditioning/refrigeration mechanics after 5 minutes of research online.  While you can be on the right track, error codes, noises and loss of function can be the tip of the iceberg in terms of air conditioning repairs required.

Misdiagnosis can waste time and cause further AC damage as you incorrectly think the system is still OK to use.  Furthermore, if you launch into repairs, the issue can actually be made worse.  This can cause great damage to an air con system.  Even worst, you can cause great damage to yourself and those around you.  It is recommended to call an expert to consult on your air conditioning issue/s and allow them to manage the repairs appropriately to maximise AC lifespan.

Timing

Sometimes we can’t help when our air conditioner needs fixing.  However, wherever possible, it is recommended to consider the timing of your air conditioner repairs.  This helps you to extend the life of your air conditioning units in many ways, but only if done correctly.

Firstly, some repairs cannot wait.  For example, gas leaks should be attended to ASAP to minimise the amount of gas lost from the air conditioning system.  However, if an air conditioner motor breaks down at the end of summer and the system isn’t needed until winter, it may pay to hold off repairs until the cooler months.

During the off-peak season, most air conditioning companies offer winter specials and more flexibility with when they can attend.  The AC repair tech is not as busy, so you may receive longer and more focused time onsite.  Aircon parts suppliers will also not be as busy, so they respond quicker with part details in order for quotes to be formed.  Parts can also be dispatched faster as they are not held up with high demand.

Overall, this results in a more pleasant, cost-effect air conditioning repair experience.  As a result, you are more likely to repair your air conditioner again in the future and work with the AC repair company to set up ongoing maintenance.  This helps you get the most out of your air conditioner and extend its life for years to come.

Noise

To extend the life of your AC system, it’s important to be aware of normal operational sounds.  By doing this, you can detect abnormal noises when they arise.  You can then do something about it to preserve your air conditioning system.

Indoor Unit

There are an array of noises possible from your indoor air conditioning unit.

• Banging/Clanging – Possible loose/broken part such as fan barrel, louver, motor, or blade.
• Squealing – Possible faulty fan motor bearings or housing. Noise may travel through ductwork.
• Rattling/Chattering – Possible loose screws/bolts, faulty fan, or failing electrical contactor.
• Clicking/Humming – Possible defective electrical component (wiring or thermostat) or loose part.
• Buzzing – Possible range of issues, including dirty filters, debris in unit, rubbing/loose parts, motor/s out of balance, pipes rubbing between units, coil icing up, and/or refrigerant leak.
• Screaming/Whistling – Possible refrigerant leak or component stuck.

These issues must be resolved by an expert in order to protect your air conditioning units and ensure a suitable lifespan.

Outdoor Unit

There are an array of noises possible from your outdoor air conditioning unit.

• Banging/Clanging – Possible broken condenser fan blade, motor out of balance, or compressor issue.
• Squealing – Possible failing condenser motor bearings or could be a normal start up sound.
• Rattling/Chattering – Possible faulty fan or contactor, loose screws/bolts, or general wear and tear.
• Clicking/Humming – Possible defective component (electrical or mechanical), loose component, or refrigerant piping vibration.
• Buzzing – Possible range of issues, including dirty condenser coil, motor/blade out of balance, pipework rubbing, components icing up, and/or refrigerant leak.
• Screaming/High-pitched Whistling – Possible jammed component or refrigerant leak.

All these issues should be assessed by an AC technician.  If the issue is not normal, it can reduce the expected lifespan of your air conditioner unit.

Refrigerant Gas

A gas leak can severely impact the health of your air conditioning system, the environment, and your family.  If suspected, it is recommended to book an aircon repairer ASAP to resolve the issue.  The air conditioner should not be used until issue resolved, otherwise major damage can occur to components such as the compressor.

You may first suspect a gas leak when the system fails to cool down the indoor space as well as normal.  If you lift the cover, you may also see ice forming on the evaporator coil.  Alternatively, water may be leaking from the indoor unit (i.e. melted ice).  Ice can also start to form on the outdoor coil and/or at the connection between pipework and unit.  This doesn’t mean that the leak is there, it just highlights that the system may be running short of refrigerant.

You may be able to hear hissing from small leaks, and gurgling from larger ones.  However, there may be no noise at all.  Another way you may detect an air conditioner being short of gas is your electricity usage.  If your power bill has increased significantly without another other explanation, it may be worth investigating your aircon.

A full gas leak search and repair is required to identify and fix all leaks.  The leak can be anywhere on the air conditioning system; indoor unit, outdoor unit, pipework, or connection between any of the components.  If the AC is less than 1 year old, it may be covered under installation warranty.  If the AC is less than 5 years old, it may be covered under manufacture warranty.  Either way, failure to resolve the issue will see a premature death to your air conditioning system.

Paperwork

Like all great things, your air conditioner will come with an array of paperwork.  This paperwork is important for many reasons and can be used to extend the life of your air conditioning units.

Licences

Firstly, before purchasing any new aircon, it is recommended to get a free quote for air conditioning supply and install in writing.  This sets out the inclusions and exclusions of your new air conditioner system as well as key details about the install company.

Next, it is recommended to check out the licences and qualifications of the proposing installation company.  For example, do they offer AC install, but fail to have a Queensland Building and Construction Commission (QBCC) air conditioning licence?  Checks like this can help ensure you are getting an air conditioner installed by an expert, which helps extend the life of the aircon.

Correct electrical licencing is also critical to ensure your air conditioner doesn’t wear out sooner than it should.  Not only is incorrect and unlicensed electrical work dangerous and can cause major property damage (including fires), it can also damage your air conditioner units.  Air conditioners come with electrical specifications such as power requirement, cable size, etc.  Failure to adhere to these specs will see a premature failure of the AC equipment.

Having a fully licenced company also ensures warranty for the new air conditioner units is maintained.  If not installed correctly, manufacturers will not honour their manufacturer warranty.  If the issue is major enough, you may be looking at throwing out your new aircon before it even reaches its expected half-life!

Receipts/Registrations

Once you have had your air conditioner installed, it is important to obtain a copy of the purchase and/or install receipt for your records.  This ensures you have important details on hand in situations that can assist with AC life extension.  However, any good air conditioning company should be able to resend a copy of your receipt at any time.

Air conditioner units typically come with a 5-year manufacture warranty, on the condition that the units are installed by a fully licenced air conditioning company/technician.  If any issues occur with the system within that 5-year period that is not caused by external causes, the system can typically be repaired at no cost to you.

However, if installation paperwork cannot be provided, manufacturers may not honour warranty work.  Effectively, warranty is void without valid install paperwork.  As a result, costs may be so significant that you find yourself throwing out the whole air conditioner and starting again with a new system.  This is particularly common with cheaper brands; the units are cheap to buy, but spare parts are terribly expensive.

Aside from installation paperwork, it also pays to register your air conditioner units and associated products whenever offered.  Sometime this supersedes the need for installation paperwork if a warranty repair is required, as the system details has already been registered with the manufacturer.  Furthermore, some AC components have an extended warranty.  For example, iZone zoning equipment comes with a 10-year parts warranty.  This can help you extend the life of your air conditioning system in the most cost-effective way.

User Manual

An air conditioner user manual is the ultimate guide for your air conditioning system.  It is sometimes called Owner Manual, Operations Guide, or Manufacturer Instructions.  Whatever it is called, it is full of useful information to help extend the life of your air conditioner units.

The manual contains operating instructions for the certain aircon model it relates to.  This helps ensure that the system is used correctly to prevent early equipment failure.  It also contains specific instructions for aircon maintenance and other ways to care for your units.  This further assists with system preservation and life extension.

When the air conditioner is installed, ask for a copy of the user manual.  If not received, just ask the installer to provide it or jump online to download a copy.  The next step is to actually read the content.  It’s probably no surprise that women tend to be far better at reading manuals than men.

Insurances

Once your air conditioner has be supplied and installed by a fully licenced installer, paperwork is received, any registrations completed, and user manual has been referred to, the next step is to review/update your home or business insurance policy.  While seemingly unrelated, this can actually end up being one of the most cost-effective ways of extending the life of your air conditioner units.

An air conditioner is a significant asset in any home or commercial building, so it should be covered by any appropriate insurance policy.  It’s worth checking what is covered and also what is exclude in relation to your air conditioning.  Common causes of damage relevant to your air conditioner includes motor burn out, fusion damage, storm events (including hail, water, or storm surge), electrical failure, fire, flood, animal, and accidental damage.

It’s worth weighting up the cost of some optional extras for your given situation.  For example, do you live in an area where flood could damage your AC?  Do you live in warmer climate where geckos (animals) wreak havoc with electrical equipment?  Is the outdoor AC unit in a carport or similar where it is at risk of accidental damage?

If the cost of repairs to your air conditioner is significant, you may think twice about proceeding with them.  For example, a compressor change in a ducted system can be half the cost of a new one.  You may consider investing the money into a whole new system instead.  However, if the repairs are related to an insured event, like a storm surge (lightening), then you are more likely to proceed with the life-extending repairs when all you have to pay is the excess.

In summary, there are many different ways to extend the life of your air conditioner units.  From the design and installation, to usage and assisting, to maintenance and supportive paperwork, there are many things you can do to support your air conditioning system.

The points outlined in this article are all cost-effective ways to support optimal AC operation and preserve your aircon system for many more years.  If you need help reviewing your air conditioning situation and extending the life of AC equipment, please don’t hesitate to contact us to discuss.

Mac vs PC.  Melbourne vs Sydney.  Coke vs Pepsi.  These are certainly some the classic rivalries that just about everyone has an opinion on.

One such rivalry in the world of air conditioning is Daikin vs Mitsubishi Electric.  While this may not get everyone fired up, it is certain a hot topic for many air conditioning providers.

Mitsubishi and Daikin are two very recognizable brands that are always in demand.  They are rival companies selling much the same product and sharing a customer base.  Whether it be as a home air conditioner or commercial HVAC system, Daikin and Mitsubishi are found everywhere.

There are many factors to consider before installing an air conditioner.  Where considering installing a home ducted air conditioning system, or investigating whether ductless aircon may be best for your small business, there is much to consider.  Once type is decided, brand is often the next major decision.

Both Daikin and Mitsubishi Electric provide top quality, reliable, durable, and high-performance cooling and reverse cycle air conditioners.  However, there are some subtle differences between the brands that we will explore.  The differences can affect all stages, from installation, to air filtration, to repairs.

Air conditioning has many benefits, beyond what may first come to mind.  The differences between the different aircon brands may be subtle, but they can have significant impact on some of these benefits.

A small difference in one aspect may be the difference between being able to install an air conditioner or not.  It can also mean the difference between an aircon system that is just OK for your home or business versus one that is perfect for the space you need to heat or cool.

Brand Origins

Mitsubishi Air Conditioning Origin

It’s worth noting that the brand name Mitsubishi is actually only half the story, as it could refer to one of two different modern-day brands: Mitsubishi Electric or Mitsubishi Heavy Industries.  It is confusing as they both share the classic Mitsubishi three red diamond logo.  However, they are two completely separate companies and have been for a long time.

The origin of both Mitsubishi companies traces back to a Japanese company founded in 1870 called Mitsubishi Shipbuilding Co.  Nearly 50 years later, in 1921, Mitsubishi Shipbuilding Co diversified and created a range of new offset companies.  This included Mitsubishi Electric Corporation.  Interestingly, the name arose from the converted factory in Kobe that used to manufacture electric motors for ocean vessels.

For the past 100 years, Mitsubishi Electric and Mitsubishi Heavy Industries (MHI) have also been rivals.  In general, Mitsubishi Electric is considered a higher-quality product than MHI.  However, that is a whole other story for another day.

When talking about rivalry or comparison with Daikin, in general and indeed in this article, Mitsubishi Electric is the brand referred to.

Daikin Air Conditioning Origin

Daikin is another Japanese manufacturing company, founded in 1924 as Osaka Kinzoku Kogyosho LP.  In 1963 it was renamed Daikin Kogyo Co Ltd.  In 1982 it was renamed again to the current name, Daikin Industries Ltd.  Or Daikin, for short.

Unlike Mitsubishi, which manufactures a wide range of different products, Daikin was established with a sole focus on air conditioning.  It pays to know what air conditioning actually is to fully appreciate their focus.

Daikin specialises in researching, designing, developing, manufacturing, and distributing air conditioners worldwide.  As a result, they have led the industry with many valuable developments.

Outside of Japan, Daikin now has operations in Australia, America, Europe, Asia, India, African, and the Middle East.  While Daikin has expanded its focus from purely air conditioning units, their heart is air conditioner based.  The chemicals, equipment, and systems that they develop typically stem from or relate back to air conditioning.

Industry Position and Innovation

As mentioned previously when discussing the origins of Mitsubishi and Daikin, Mitsubishi has been operating for longer than Daikin as a company in general.  However, Daikin is more purely focused on all things air conditioning.

Daikin Industry Position

Daikin is considered the industry leader for many reasons, including a large research and development team for one.  Valuable developments Daikin have been involved in include, but is not limited to:

• Ongoing advances in chemical development, especially fluorochemicals,
• Development of R32 refrigerant, a more environmentally-friendly aircon gas,
• Invention of variable refrigerant volume (VRV) technology, which allows energy efficient simultaneous heating and cooling from units in the same system, and,
• Invention of the world’s first split system with built-in humidification technology; the US7.

These are just some of the many valuable advancements that Daikin can claim.  There will no doubt be many more to come.

Mitsubishi Electric Industry Position

Mitsubishi as a broad company is involved in many different areas; tools, equipment, cars, shipbuilding, aviation, missiles, and even aerospace components.  However, the 1921 spin off –  Mitsubishi Electric, is focussed on household goods and electronics.

Mitsubishi Electric has been in the industry a few years longer than Daikin on the air conditioning side and has certainly cemented its place as being one of the best brands available.  Mitsubishi have developed a few features of their own, like Dual Barrier Coating and Quiet Mode.

However, Mitsubishi does tend to take its lead from Daikin.  Daikin technology has shown up in Mitsubishi Electric aircons, includes the use of R32 refrigerant in new AC units and Blue Fin anti-corrosion treatment on outdoor coils.  Mitsubishi also uses VRV technology under the name Variable Refrigerant Flow (VRF), as VRV is copyright to Daikin who invented it.

Split and Ducted System Range

Before we look at the brand differences, we need to know what units we are talking about as there are many different types of air conditioning unit.  In this article, we will focus mostly on individual split systems and split ducted systems used as home air conditioners or in light commercial application.

Split Systems, or Splits for short, typically refers to AC systems with wall, floor, and even under ceiling mounted indoor units (not to be confused with a cassette unit which is visibly mounted in the ceiling).  There is then a separate outdoor unit, connected by refrigerant pipework and interconnect cable.  Hence the term: split system, or splits.

Split Ducted Systems, or Ducted for short, also have an indoor and outdoor unit, but also have ductwork of some description or at least the indoor unit sitting in the ceiling space.  Air is then blown out into the room without the indoor unit being visible.  Ducted systems differ from other split system in this way.

The Daikin air conditioner split and ducted range covers all types of small and larger homes, providing a comfortable indoor environment in varied Australian climates.  Mitsubishi Electric also has a range of both split and ducted units to suit a wide range of home designs and spaces available.

Daikin Split System Air Conditioners

Daikin split system range currently consists of 8 main model types; US7 Series (FTXZ-N), Zena Series (FTXJ-T), Alira Series (FTXM-U/P), Cora Series (FTXV-U/L), Lite Series (FTXF-T), Project Series (FTXF-Q), Nexura (FVXG-K) Series, and Floor Standing Series (FTXS-R/L).

Daikin split cooling capacity ranges from 2.0kW up to 9.4kW.  However, not all series include all of the sizes.  You can find more information in the Daikin Split System Brochure, or the separate one for Daikin Lite Series.

The Zena Series is considered the most stylish of all the wall split systems.  Daikin Zena has an aesthetically pleasing compact, rectangular design.  It also comes with a choice of 2 colours; Black Wood or White Hair Line.

There are many other differences between Daikin wall split air conditioners.  It’s highly recommended to review the different series and find the best Daikin wall split air conditioner for you.

Mitsubishi Electric Split System Air Conditioners

Mitsubishi Electric split system range currently consists of 5 main models; MSZ-AP Series, MSZ-LN Series, MSZ-EF Series, MSY-GN Series (cool only), and MFZ-KJ Series (floor model).

Mitsubishi splits unit may be a home designer’s dream with multiple colour choices.  The MSZ-EF Series has the option of 3 different colours for the indoor unit across the range; Glossy Black, Matte Silver, and Classic White.  The range contains 4 system capacity options, up to 5.0kW.

The MSZ-LN Series is similar to the Daikin Zena in design; rectangular, stylish, and compact.  It comes with the option of Black, White or even Red!  Red may not be the most common or popular colour, but it’s certainly a great point of difference and option in the quality wall split system range.

Daikin Ducted Air Conditioners

The Daikin ducted air conditioning range currently consists of 4 main series: Daikin Inverter Ducted Series (FDYAN/FDYQN), Daikin Premium Inverter Ducted Series (FDYA/FDYQ), Slim-Line Ducted Series (FBA), and Bulkhead Ducted System Series (FDXS).  More information is available in the Daikin Ducted Systems Brochure.

Daikin ducted units have cooling ratings from 2.4kW to 24.0kW.  This means that there is likely to be a unit capacity available to suit your home.  If the house is double storey or particularly large, 2 (or more) systems can be installed.

Daikin Standard Inverter range comes with the option of single phase or three phase power for 6 common ducted sizes; 7.1kW, 8.5kW, 10kW, 12.5kW, 14kW and 15.5kW.  Unfortunately, Daikin removed such variation in power phase from their Premium range as of 2021.

It’s worth noting that Daikin units can ramp operations up and down to vary the cooling and heating capacity of the system.  With this in mind, the functional capacity range for Daikin Ducted units becomes 1.3kW to 27kW.

Ramping up is helpful to quickly cool down or heat up the indoor space.  This can also provide an added boost when the outdoor temperature is extreme (very hot or very cold).

Ramping down is helpful to reduce the amount of power required to operate the system, while still achieving suitable temperature control.  Ramping down also helps decrease energy usage and subsequent power bill, as it decreases the cost of running the air conditioning

Daikin Premium Inverters are better able to ramp up/down in response to demand compared to Daikin Standard Inverters.  This extends the higher end of the operational kW range of the premium systems.  This, along with some other technological advancements, results in a Premium Ducted System being ~10% more energy efficient than the same kW-rated Standard model.

Daikin’s slim-line range of ducted units are designed to fit into tight roof spaces.  The bulkhead units are also a compact option and the most discrete option available.  With only the controller, return air, and discharge grilles visible, these systems can fit in with just about any indoor décor.

Mitsubishi Electric Ducted Air Conditioners

Mitsubishi Electric ducted air conditioner range currently consists of 3 main series;

Mr Slim PEAD Series (PEAD-M-JAAD), Mr Slim PEA Series (PEA-M-GAA/WJA/HA), and SEZ Series Bulkhead (SEZ-KD-VAQ).  More information can be found in the Mitsubishi Electric Ducted Systems Brochure.

Mitsubishi ducted units have cooling ratings from 2.5kW up to 22kW.  Each unit comes with a capacity range, as do Daikin units.  That means that the system can operate at slightly higher and lower capacities.  With this in mind, the functional capacity range for Mitsubishi Electric ducted air conditioners becomes 1.4kW to 27kW.

Mitsubishi Electric offer several three phase options in the smaller ducted air con sizes, e.g. 10kW, 12.5kW and 14kW in the standard range.  The units have solid features across the ranges, such as PEAD-M-JAAD models that are designed to operate quietly both day and night.

Mitsubishi ducted units are designed for tight ceiling spaces.  Hence the range name; Mr Slim.  Mitsubishi indoor units tent to be smaller compared with Standard Daikin ducted units of the same capacity (kW rating).  This physical size difference can make or break a ducted install; some tight roof spaces may only fit a Mitsubishi unit when comparing standard ducted systems

Technology and Functionality

Like anything electronically based, technology has come along way.  Air conditioners are no different.  There is an incredible number of technological advancements and features backed into every single air conditioner unit in the Mitsubishi and Daikin range.

Daikin AC Technology

When it comes to air conditioning technology, there is no doubt that Daikin is the leader.  With a dedicated research and development team, Daikin strives to and successfully leads the way in all things air conditioning related.  Examples include chemical compounds, refrigerants, simultaneous heating/cooling, advanced fresh air, and humidification systems, just to name a few.

Daikin wall split systems come with a range of features.  Energy-saving Intelligent Eye, an array of smart timers, Coanda Airflow and draft prevention, plus an extensive list of advanced technology packed into compact size.  These are just some of the top features in various daikin split air conditioners across the range.

Daikin ducted air conditioners are also feature-packed.  With remarkable performance, energy efficiency, flexible duct design, and the ability to retrofit premium AC units to R22 pipework, they are just about as good as it gets for ducted air conditioning.

Daikin ducted units are compact for what they contain.  Next-level space saving comes in the form of bulkhead units.  Bulkhead units are the perfect choice to achieve a discreet install when ceiling space is limited.

With a bulkhead system, the indoor unit sits flush to the ceiling, with only the supply and return air grilles visible indoors.  This leaves plenty of space in a room for decorations, furniture, fixtures, and fittings.  They are also whisper quiet, so you’ll barely notice it’s there.

Mitsubishi Electric AC Technology

Mitsubishi Electric air conditioners are also feature-packed, helping to keep them up there with Daikin as an industry leader.  Many of their features are similar to the Daikin range, with a few tweaks to make them their own.  Some features are different, showing that Mitsubishi Electric can stand on its own as a leading air conditioner manufacturer.

Common features of Mitsubishi split systems, similar to Daikin splits, include Blue Fin Condenser treatment, advanced modes (i-Save, EconoCool, and Night modes), constant airflow patterns, and emergency and long operations.

New Mitsubishi Electric ducted air conditioners also now come with R32 refrigerant across the range.  They also come with flexible duct design and improved air flow due to high static pressure.  Certain Mitsubishi units can have up to 75m max pipe run.  Although it’s important to note that the longer the pipe run, the less efficient the system becomes.

Other points of difference include two-piece construction and two-way maintenance access for the PEA-M-HAA ducted range, for ease of installation, maintenance and repairs.  The PEA-M-GAA ducted range also offers computerised dehumidification.

Controls and Building Management Systems

From split system remotes, to wall controllers, to complete building management systems (BMS), Daikin and Mitsubishi offer high quality control with all of their products.  Their controllers have varying degrees of functionality.  Smart air conditioning controllers can have programmable schedules (day, week, and some even for a year) and zoning system integration.

Daikin Controllers

Daikin aircon remotes come in different shapes and sizes, from the Lite range up to the US7.  Precision control of 0.5 degree Celsius temperature adjustment and convenient On/Off timers both come standard.  Daikin remote controllers reflect all the features of a Daikin split system, but are also clear and easy to use.

Wi-Fi control for Daikin split systems comes as either standard or can be easily added, either during install or at a later date.  Hard-wired wall controllers can also be fitted to Daikin split air conditioners.  This is quite handy in offices and organisations where the remote controller is prone to going missing.

Daikin wall controllers come with a range of high-tech features.  Daikin control panels include lock systems and temperature limits to reduce energy waste.  As with ductless aircons, Daikin ducted controllers are easy to use and program with the Daikin Airbase App.

Daikin zone controller options include 4 zone or 8 zone control integration, including the BRC24Z4(8) and BRC230Z4(8) models. – Add Daikin zoning controller brochure to wordpress and add link to it here.  They can be stand alone for zone control or integrated to run both the Daikin aircon unit and zoning system.  Daikin zoning controls are one of, it not the most, popular air conditioner brands of zone controller on the market.

For Daikin large-scale commercial air conditioning controls, there is an extensive range of centralised controllers on offer to manage whole building HVAC systems.  Examples include the BACNet/LonWorks Interface, iTouch Manager Centralised Controller, and Individual Control Systems.

Daikin’s design and construct team can create almost unlimited combinations of units and controllers.  Systems can be designed specifically to a building layout and usage.  This allows Daikin units and controls to be tailored to just about any residential or commercial project you can imagine.  You just need a commercial air conditioning installation expert to attend, assess, and go from there.

Mitsubishi Electric Controllers

Mitsubishi aircon remotes also reflect the array of features offered with their ductless split systems.  Common timers include 24 hour and/or weekly settings.  Clear buttons and easy-to-use controls comes standard.

Mitsubishi Electric’s ducted wall controllers are also user friendly, with touch-button climate control.  Like Daikin, there are also zoning controllers available in the Mitsubishi range.  Similarly, Mitsubishi Wi-Fi either comes standard or can be easily added to an air conditioning system.

For Mitsubishi Electric commercial air conditioning controls, there is a wide range of controllers to suit business needs.  Mitsubishi offer 8 different controllers/interfaces, including interfaces with touch screens, and allow energy data filters to be uploaded.  With connection to up to 50 units, there is a controls set up to suit most buildings.

Mitsubishi Electric’s BMS and control systems can be controlled from a central point as individual area data can be managed via a browser.  Individual area climate control can be achieved by monitoring and responding to this live steam of data.  The Power PC Platform offered by Mitsubishi also supports the use of multiple power options.

Noise

Noise is an important factor to consider when looking to buy a new air conditioner.  Air conditioner units work hard, so they will obviously make some noise.  However, it is possible for this noise to be minimised in many ways; in the unit itself, installation, usage, maintenance, and repairs.

Noise levels are measured in decibels (dB).  Ambient noise in our everyday parks and suburbs is around 40 dB, while a whisper would be around 20 dB.  It is reasonable to expect new split air conditioners to be no louder than 40 dB, depending on kW rating.  For the outdoor unit, you wouldn’t want it to be more than 5 dB over the usual ambient noise, especially at night.

Daikin Air Conditioner Unit Noise

Daikin’s advanced technology has resulted in some of the quietest air conditioning units around.  Such technology includes Daikin split units includes Saw Edge indoor fan motor design, Advanced Cross Flow Fan with large diameter rotor and aerofoil blade design, specially designed Coanda Airflow discharge louvers, and condenser DC fan motor, just to name a few.

Daikin aircon sound levels are included in product specifications.  However, it can be confusing then there are multiple numbers involved.  There will be multiple lines referring to sound, as the indoor and outdoor aircon units have different sound levels.

In Daikin split system product specification tables, noise is typically reported as Sound Level (H/SL); H = on High fan, SL = Sounds Level.  The SL figure will be lower, and that is the figure you should look at when comparing to other brands to ensure you are comparing apples with apples.  Daikin wall split indoor units can run as low as 19dB in heating.  This is quieter than a whisper!

Mitsubishi Electric Air Conditioner Unit Noise

Mitsubishi’s advanced technology has resulted in some of the quietest air conditioning units around.  Such technology is often stems from or is very similar to Daikin, including specially designed indoor and outdoor fan motors, louvers and blades.

Noise reduction or quite mode in the Mitsubishi splits is a standout feature.  Noise during operation can drop to as low at 18dB for the MSZ-AP25 unit while heating.  This is quieter than a whisper and 1dB quieter than a comparable Daikin unit.  This makes them ideal as bedroom aircons.

Mitsubishi ducted units with Night Mode drops the decibel reading of the units while maintaining indoor comfort level.  The small drop in decibels actually makes a significant difference to the noise heard by occupants and neighbours.  Not only can occupants sleep better, but neighbours will be grateful too.

Mitsubishi Electric also promotes the fact that its units have high static pressure fans.  This helps improve airflow while noise is kept to a minimum.

Energy Efficiency

There is an increasing demand for energy efficient air conditioners that save money and the environment.  Most aircon brands have stepped up in response to this demand, especially Daikin and Mitsubishi Electric.

For more specific information, it’s recommended to look at the product specification for each air conditioning brand and compare the specific models you are considering.  Key figures to look at include EER/COP in cooling and heating plus star rating.  The greater the kW rating, the lower the efficiency by default, so be sure to compare the same kW rated units for accurate comparison.

Daikin Energy Efficient Air Conditioning

Daikin split systems have advanced technology that makes them some of the most energy efficient air conditioners in every range.  Advancements and additions to achieve this includes intelligent sensors, energy saving modes, greater surface area on heat exchanger coils, DC motors, aerodynamic blades, and new louver designs.

The standout has to be the Daikin US7, with the 2.5kW model achieving 7-star super efficiency rating according to the Australian Government Energy Ratings.  This system is packed full of other extras including humidification, fresh air mode, breeze simulation airflow, and advanced filtration system.  The price reflects this truly advanced wall split HVAC system.

Daikin ducted air conditioners also come with advanced technology to help the environment and your hip pocket.  Daikin premium ducted systems have better compressors and ability to ramp down, making them about 10% more energy efficient than standard ducted aircons.

All Daikin ducted systems exceed the Australian Government’s Minimum Energy Performance Standards (MEPS), which set out the minimum level of energy performance various products must have.  Furthermore, programmable temperature limits, lock-out system, Wi-Fi controls, and timers can be used to enhance the energy saving possible.

Mitsubishi Electric Energy Efficient Air Conditioning

Mitsubishi Electric also have an impressive range of energy efficiency aircon systems on offer.  The advanced technology they have adopted and incorporated into their air conditioners is to thank for this.  The use of more environmentally friendly refrigerants, DC motors, inverter technology, and quality motors are just some examples.  They also have some of their own features like wider and longer airflow patterns.

Mitsubishi Electric units also see energy savings through their brand-specific Econo Cool temperature control.  This feature involved the adjustment of airflow into a room depending on air outlet temperature.  It allows set temperatures to be raised by 2ºC without affecting room comfort, which in term providing a 20% gain in efficiency.

Mitsubishi ducted air conditioners also come with technology advancements the make them some of the most energy efficiency on the market.  Mitsubishi ducted aircons also exceed Minimum Energy Performance Standards (MEPS) and offer added saving through clever timers and Wi-Fi control.

Air Filtration

Air filtration and purification is increasing in demand due to increased air pollution and a rise in allergies.  Air conditioning, in part, conditions the air that we breath indoors.

This means that air conditioning can improve the indoor air quality and helps prevent us from getting sick.  While this is valuable in homes, it is essential in a workplace.  However, it is dependent on routine aircon servicing, otherwise the reverse can occur.

Daikin Air Filtration

Daikin’s wall split systems and air purifiers are approved by the National Asthma Council Australia’s Sensitive Choice program.  The National Asthma Council recognises the advanced systems on offer from Daikin that help manage, reduce, or prevent common allergy triggers.

Common allergy triggers include pollens, dust mites, insects, pet dander/hair and mould.  Airflow, humidity, and air filtration all play a part in managing such allergens.  Allergic reactions can range from mild to life-threatening, so air conditioner assistance in allergy management is most certainly worthwhile.

Many of Daikin’s split systems contain advanced titanium air filters.  These filters trap microscopic particles, deactivate bacteria and viruses, decompose odour, and help to purify the air.

Daikin’s Dry Function helps via powerful humidity (moisture) removal to help prevent mould growth indoors.  This is why Daikin splits carry the blue butterfly symbol.

Mitsubishi Electric Air Filtration

Mitsubishi Electric may not have national recognition for their air filters, but it’s not to say they don’t have a high-quality filter system.  Mitsubishi have their own claim to cleaner air fame;  Plasma Duo Filter Systems.

Mitsubishi’s Plasma Duo Filter Systems uses a combination of technologies to achieve state of the art air purification and deodorisation.  The system consists of Plasma Air Purifying Filter combined with a Plasma Deodorising Filter.

The Plasma Air Purifying Filter removes substances like dust, dander, pollen, viruses, bacteria, etc.  Static electricity is used to catch the allergens and pollutants.  Negative ions then act to neutralise them.

The nanometre scale-meshed platinum catalyst deodorising filter works by trapping odour causing particles.  Such chemical particles include ammonia, hydrogen sulphide, trimethylamine, and methyl mercaptan.  Particles are then decomposed and eliminated by ozone generated from the plasma electrode.

After-Sales Service and Support

We often don’t stop to think about after-sales support when buying new products.  After all, there is so much to consider and research upfront, who has time to look at the complete lifecycle of a device?  However, it really does pay to stop and consider it for a moment, no matter what product or brand you are purchasing.

Daikin Air Conditioning Service

Daikin have a large fleet of air conditioner service and repair technicians available to attend to any Daikin aircon, new or old.  They are also known for having an extensive network of Daikin Warranty Agents in Brisbane, Australia, and World-Wide.

Daikin offer regular, intensive training to not only their own employees but also Daikin air conditioning contractors around the world.  For installation, service, repair, and other technical matters, Daikin have valuable training for the many different air conditioner types available.  Training is further broken down into aircon stage e.g. installation, diagnostic/repair, etc.

Daikin also offer a range of specialised diagnostic tools that help any Daikin expert test and service Daikin units with impressive speed and accuracy.  These tools are accompanied by high-level software for advanced comprehension and assist the AC tech in taking the correct actions.

Daikin also offer a service-friendly App; Daikin eQuip.  Any qualified air conditioning/refrigeration mechanic has access to the Daikin App with the use of their Refrigerant Handling Licence.   eQuip provides access to all the Tech data and information an air con contactor could need for productive work on modern-day Daikin air conditioners.

If more assistance or clarification is needed, Daikin also have a Tech Support Hotline for technicians to phone.  During the peak of summer, wait times can be high.  However, they offer a call back service to ensure technicians are not left holding on the phone for long periods of time.

If all that wasn’t enough, Daikin also offers a web-based Portal for Daikin Dealers to log into to access an extensive range of valuable information.  Engineering data, technical specifications, unit diagrams and images, just to name some of the useful documents readily available through the Daikin Portal.

Overall, Daikin are known for the highest level of support at all levels.  This can save a lot of time, money, energy, and frustration down the track as you look to maintain your new air conditioner throughout its complete lifespan.

Mitsubishi Electric Air Conditioning Service

Mitsubishi Electric also provide high-level support, but it’s hard to top Daikin’s next level service provision.  Mitsubishi have a network of warranty agents in Brisbane and around the world.

Mitsubishi Electric also offer training to Dealers and Agents, related to many of their different AC unit types.  Mitsubishi also have specialised diagnostic tools and software to assist with service and repairs when required.

Mitsubishi also have a Tech Support Hotline for technicians to phone if required while undertaking Mitsubishi aircon repairs.  They can also be contacted via email with reasonable response rate.  They also have a Technical Information portal for handy access to a range of useful documents.

Overall, Mitsubishi provide solid after-sales support.  Certainly far better than many other brands.  However, it’s hard to compare to Daikin who are an example how it can be done when you are solely focused on air conditioning.

Aircon Repairs and Spare Parts

Daikin Aircon Repairs

As mentioned under After-Sales Support, Daikin have an extensive network of air con service and repair experts around the world.  They offer comprehensive brand-specific tools, software, phone application (Daikin eQuip), and web-based portal to support AC repairers in the field.  They also offer training to all their own technicians and Daikin Dealers, with phone support available when required.

Daikin also provide a range of handy How To videos online to help users service their new air conditioner units.   This helps maintain the aircon, extend its expected lifespan, and reduces the risk of breakdowns.  It can also help with some common call out issues, such as poor performance because of dirty filters or weird things happening with the Daikin wall controller.

When it comes to spare parts, Daikin service continues.  Their spare parts department is on par with the high-level service expected.  You can phone or email the spare parts team for assistance working out which part you need, price, and availability.  Daikin have also taken over other brands over the years, such as parts of McQuay, and can assist with spare parts for some of these aircon units too.

If you don’t want to email or call, you can instantly access interactive unit explosions and part lists online via Daikin’s Global Service Data Base (GSDB).  Any Daikin account holder can log in and search by different categories such as Model Number or Part Number to find what they need.  Information available includes part and possible substitute part number/s, price, number of that part in stock in NSW, just to name a few key pieces of information.  All data can be downloaded for reference later or parts can be ordered directly there and then.

Parts can also be ordered via email direct to the spare parts team.  Furthermore, Daikin Distribution Centres (DDC’s) are popping up around the country which also stock common spare parts to speed up repairs.  For example, if the part is in stock locally then you can expect fast air conditioning repair in Brisbane, Gold Coast, and everywhere in between with DDC’s in Geebung and Nerang.

If the part is not in stock and has to come from interstate, the parts are usually dispatched either same day or following day depending on when the order is placed.  During summer and peak times, it can take an extra few days to be dispatched, and even longer to arrive due to freight demand in the lead up to Christmas.  Airbags for small parts can see delivery within a matter of days and larger road freight items within a week.  Overall, it is much better than most if not all other air conditioning manufactures on the market.

Mitsubishi Electric Aircon Repairs

As mentioned under After-Sales Support, Mitsubishi Electric also have a network of specialists aircon service and repair technicians around the world.  Mitsubishi also offer comprehensive brand-specific tools, software, training, and dedicated phone number to assist aircon repairers out in the field.

Mitsubishi Electric make it a little more difficult than Daikin to obtain spare part details, including part number, price, and availability.  Typically, you need to provide an account number when obtaining part numbers and pricing over the phone.  There is no online login to quickly obtain part information unfortunately.

When ordering parts, you have to do it via email and include the serial number of the air conditioner unit being repaired.  This could be challenge/delay the process if the serial number was not recorded at the time of the initial breakdown/site visit.  Parts also take longer to arrive from interstate.

If there is an issue with a part number, a reply email is typically sent in response to the purchase order.  This can be missed with the volume of emails often received these days.  This is unlike Daikin for which it is not uncommon for them to phone you to clarify an order, rather than sending an email and delaying the parts dispatch process further.

Mitsubishi Electric do provide high-level breakdown/repairs support, but it’s hard to top Daikin in this area.   Their staff are spread across all categories of product, from air

conditioners units to aerospace components.

Summary

Companies and individual air conditioning contractors can be bias to whichever brand they primarily sell.  However, good AC companies should sell, install, service, and repair both brands.

It’s good practice to quote both brand options for new installs where suitable and allow individuals the opportunity to decide.  However, when working with customers and discussing requirements, one option may be more suitable than another and quoted accordingly.

Mitsubishi Electric are no doubt a high-quality air conditioner manufacturer, with a league of loyal customers.  They have received industry certification and expert endorsements.  Mitsubishi has a range of compact, stylish, quiet, and high-tech air conditioning systems to suit many homes and businesses.

Daikin also has an extensive range of air conditioner units to suit just about any residential or commercial HVAC requirements.  If they don’t have it, they can typically design and construct it to suit.  Overall, Daikin tends to come out on top with their innovation, technology, product range, reliability, and after-sales service.  They have won many industry awards and continue to excel with their air conditioning focused approached.

At the end of the day, the great Mitsubishi Electric vs Daikin air conditioning debate largely comes down to personal preference.  There are some minor differences between the brands and their products which may be the deciding factor, depending on your specific aircon requirements.  However, both brands offer excellent value for money, provided you buy from a Mitsubishi or Daikin Dealer.

If you have any questions about with brand, or need help deciding which AC brand is best for you, it is recommended to reach out to an experienced air conditioning company that can provide both Daikin and Mitsubishi options.  That way, they can answer any questions you may have about either brand and give you pricing options on both!
