What causes my air conditioner to freeze up?

Your air conditioner may come in handy when experiencing very high outdoor temperatures. However, like other machines, air conditioners may develop faults. One of the common faults you may have encountered is air conditioner freezing. Have you ever wondered why your air conditioner may be freezing up?

We shall highlight some primary reasons why your air conditioner may freeze up. It is critical to find a professional air conditioner expert to provide good repair whenever you have such a complaint. But first, let us find out the possible reasons your air conditioner may freeze up.

Poor Quality Airflow

One of the most common air conditioner freezing issues may be poor airflow. Airflow is critical to the operation of your air conditioner. Poor quality airflow may cause humidity to settle on the air conditioner coils, which in turn may cause them to freeze. The air filters around the air conditioner should be clean and free of dust to prevent clogging.

Insufficient Refrigerant

Another reason your air conditioner may freeze up is insufficient refrigerant. Your AC refrigerant helps to cool the air before entering your home. For your air conditioner to function efficiently, it must receive an adequate refrigerant. The compressor in your air conditioner utilizes the refrigerant to ensure the effective pumping of cool air in your home.

A pressure drop may occur inside the AC unit when to the low refrigerant volume. A decrease in pressure in the system may also reduce the temperature within the vaporization coils. A further drop in temperature may reach freezing points and cause water vapours around the unit to freeze.

Insufficient Power to the AC Fan

A likely reason your AC may freeze up could be a fault in your home’s electrical system. Air conditioners utilize high energy, and when the power supply to the blower motor or fan is insufficient, it may cause your AC to freeze.

Faulty AC blower motor

Your air conditioner fan or blower motor helps blow air over your AC coils, creating cool air. Failure of this fan to work may restrict the flow of cool air from your vents which could also cause the AC unit to freeze.

Blockages on the Air Conditioner coils

Dirty air filters and dust particles accumulating on your air conditioner coils may be responsible for freezing. Since your AC coils are wet due to moisture from the surrounding, dust particles may easily stick to the coils. Dust may insulate the coils, prevent cold air escape, and cause ice to form around them. Further moisture accumulation around your AC coils may increase the thickness of the ice sheets.
