An air conditioner refers to systems designed to cool the air in an occupied space to comfort occupants. They operate in both domestic and commercial places. Air conditioners use a fan to disperse the conditioned air to enclosed spaces such as cars and rooms to improve indoor air quality and thermal comfort. However, there are various grounds why an air conditioner freezes up. Thankfully, there are ways on how to unfreeze an air conditioner so you will still be able to use it.
Why Air Conditioner Freezes Up?
Air conditioners sometimes freeze up. There are various reasons why the air conditioners freeze up, such as, but not limited to, the following:
Blocked Air Flow
Dirty filters cause the air conditioner to freeze up. The air conditioner has to have a continuous airflow, so the humidity cannot settle on the coils and freeze. To maintain the airflow is moving, you need to be sure that air filters are checked regularly and ensure that your air conditioner is always and tuned up.
Refrigerant is an essential part of keeping the regulated temperature of the machine. If the refrigerant level is very low, it may also cause freezing up. If this issue happens, you should have your air conditioner fixed.
Cool Summer Nights
When the summer nights are colder than usual, it also caused the air conditioner to free up. When this happens, just shut down the air conditioner.
