Why Does My Air Conditioner Keep Freezing Up?

Air Conditioner Keeps Freezing Up

The evaporator coil is the part of your air conditioner that freezes up. It is responsible for transferring heat from the inside of your home to the outside. There are several reasons your evaporator coil may freeze. Learn 5 reasons why your air conditioner is freezing up below.

5 Reasons Why AC Units Freeze Up

1. Insufficient Airflow

Your air conditioner keeps your home cool by removing heat from it. If there is insufficient airflow, then this heat exchange cannot properly take place. This can cause your evaporator coils to freeze.

2. Low Refrigerant Levels

If the refrigerant level is too low, then it will cause your evaporator coils to become too cold. Air that comes in contact with your evaporator coil will freeze. Fortunately, a professional can easily resolve this issue.

3. Faulty Fan

Mechanical issues, such as a problem with your air conditioner’s fan, can restrict airflow and cause your air conditioner to freeze up.

4. Dirty Air Filter

Your AC can also freeze up due to a dirty filter. Your air conditioner’s air filter is in charge of catching air pollutants before they enter your home’s air ducts. Over time, these pollutants and allergens build up in your air filter, restricting the airflow. When the filters start restricting airflow, it becomes harder and harder for air to enter your home, and more importantly, your AC system. Try replacing your air filters to help allow air to flow freely throughout your home.

5. Low Outside Temperatures

Did you know you should not run your air conditioner if the temperature outside is less than 62 degrees Fahrenheit? This can cause pressure inside of the air conditioning system to drop. As a result of this, the evaporator coils can freeze.
