The good news is that there are some things that you can do to fix this problem. Keep reading to learn how to repair a frozen evaporator coil.

Clean Your Evaporator Coils Regularly

One of the best ways to keep your coils from freezing is to clean them on a regular basis. Evaporator coils can sometimes collect debris and dirt quickly, so it’s important to clean them frequently. In most cases, evaporator coils only need to be cleaned about every three months.

If the evaporator coil isn’t too dirty, compressed air will usually do the trick. It’s important to blow the air in the opposite direction of the normal airflow across the evaporator coil. Always wear eye protection when doing this. If there’s a lot of dirt build-up on the coil, a brush can be more effective. Plus, you can control the pressure better and make sure you’re only cleaning the areas you want to. When using a brush, choose a soft one, so you don’t damage the fins.

Reapply as needed or according to instructions until the coils are clean.

Ensure Proper Insulation

The most important thing you can do to prevent your evaporator coil from freezing is to make sure it is properly insulated. The insulation helps keep the cold air inside the coils so it can do its job of cooling your home. If there is any damage or deterioration to the insulation, replace it right away. You should also check for any leaks around the coils as they could let in warm air and cause the coils to freeze. Make sure all ducts and vents are properly sealed so that no warm air enters your home unnecessarily.

Change Your Air Filters Regularly
