Why Is My Air Conditioner Freezing

Why Is My Air Conditioner Freezing

When the outside temperatures start rising, you’re going to want your AC to pump out ice cold air to make you feel comfortable. But there is a big difference between ice cold and actual ice. You may start to notice that your air conditioner is starting to produce more ice than air, which is definitely not what you want it to be doing. If your air conditioner is freezing, these may be some of the reasons why.

There’s low air flow.

Your AC functions by taking in warm air from your home and cooling it. If there isn’t enough airflow, then it won’t be able to take in enough warm air and the condensation that develops in the unit can turn to ice. Low air flow is typically caused by dirty filters or leaking or blocked vents.

There’s not enough refrigerant.

As refrigerant passes through your unit, it can cause condensation to develop on its line and condenser. If there isn’t enough refrigerant in your system or the pressure at which the refrigerant is kept changes, that condensation can freeze on the condenser and coils. You may need to have the system recharged by a professional in order to stop the freezing.

The blower fan is broken.

Your blower fan’s job is to push cold air where it needs to be in your home and push warm air out of your home. If the fan becomes damaged or stops working, it changes the airflow in your system and allows condensation to build and freeze up, since there is no warm air getting rid of it as a normal system would do.

Not only is your air conditioner freezing inconvenient, but if the root issue behind it goes unfixed, it could cause some serious damage to your HVAC system.
