3 Common Reasons Why Your AC Is Freezing Up

Posted on July 29th, 2022 by Devine Bros

This summer has been a very sweltering month. With the heat waves we’ve been getting, it’s hard to believe anything can be cold. However, if your air conditioning suddenly starts to freeze up instead of cooling you down, then you may have some problems on your hands. 

But what causes your AC unit to freeze? This can happen in multiple ways, but paying attention to these three common reasons is important so you can take care of the problem as soon as possible.

Poor Airflow

Poor airflow is one of the most common reasons why your AC unit may be freezing up. This can be caused by several things, such as a dirty air filter, closed vents, or even furniture blocking the vents. If you suspect poor airflow is to blame, be sure to check your air filter and vents first.

Low Refrigerant Levels

Another reason your air conditioner is freezing up is due to low refrigerant levels. When the refrigerant levels are low, it means there isn’t enough coolant to absorb the heat, causing the coils to freeze. This can be caused by a leak in the system or simply by the unit not being properly charged. Either way, it’s a problem that needs to be fixed by a professional.

Clogged Condensate Drain Line

When your AC’s condensate drain line is clogged, it can mess with the whole system and cause uneven cooling. This line drains the water that collects on your evaporator coils, and if it gets backed up, it can cause your coils to freeze. You can clean your condensate drain line yourself or hire a professional to do it for you.
