Why Is My Air Conditioner Freezing Up?

Posted on July 7th, 2020 by Devine Bros

It may seem strange, but your air conditioner freezing is actually more common than you would think. If you notice the area surrounding the evaporator coils (which is located near or inside the area that holds the blower fan) has ice on it, your A/C is well on its way to become frozen and can stop working. And this chilly issue will lead right to your home becoming extremely hot on a summer day! But, what causes the ice to form?

Blocked Air Flow

If your air conditioner doesn’t have proper airflow, it may lead to the condensation inside, which eventually begins to freeze. The warm air needs to be able to come through in order to regulate temperatures inside. A simple fix for this is just to switch out your air filters, as some debris might have caused some issues with your airflow.

Leaking Coolant

Your coolant, or refrigerant, works to integrate warmer air into your system safely and effectively. If there is a leak, there will be less pressure for this part of the system to work with, thus making it harder to absorb heat. As a result, freezing will occur. You’ll have to call a professional to help fix this issue. 

Dirty Evaporator Coil

Your evaporator needs warm air in order to remain functioning. If some dirt or debris builds up on it, that can block the coil from getting any warm air. Freezing will occur very quickly after this, so have your coil checked and maintained regularly. 

Broken Blower Motor

In order to keep air flow moving inside your air conditioner, the blower motor is very important. If any part of this system is broken, especially the blower fan, air will stop regulating inside and the coils won’t receive the heat they need. You’ll know if this part is broken if you hear rattling.
