Tips For Repairing Your Frozen Evaporator Coils

Posted on

Your air conditioning system's evaporator coils play a large role in getting the job done but you need to keep an eye on this part of your A/C in order to ensure the system is operating efficiently. If your air conditioner is no longer working correctly, one possible issue could be that the evaporator coils have frozen over. If this is the issue you are dealing with, here are some areas to check to see if you can locate the source of the problem.

Check the Thermostat

Does your thermostat need cleaning? Do the batteries need to be replaced? Is there another issue that's causing it to malfunction? If your thermostat is causing your air conditioner to keep running, your evaporator coils are never going to get a break. Constant running of the system will cause the coils to become too cold over time and eventually, they will freeze over. Clean or replace your thermostat if needed and see if that solves the issue.

Check Your Refrigerant Levels

When was the last time you checked your refrigerant level? If the level gets too low, your air conditioner won't be able to do its job effectively, and this will put more strain on the coils, again forcing them to keep working. Top off your refrigerant and the problem may clear up.

Clean or Replace Your Air Filter

Poor airflow can also be a problem for evaporator coils. If your current air filter is clogged, clean it out or swap in a fresh one. Better airflow will prevent ice from forming on the coils and everything should go back to normal.

Check Ducts and Vents

Your air filter is not the only spot within your air conditioning system where an airflow problem could occur. Check your ductwork and all of your vents. Are there any obstructions stopping the proper flow of air? Remove the obstruction or contact an expert for help.

Your Air Conditioner Can't Handle the Heavy Load

If you've recently installed a new air conditioner unit but you've noticed this issue with frozen coils soon thereafter, it may be that the air conditioner is the wrong size for your house. If the air conditioner can't handle the load of cooling your entire house, you may need to return the unit and get one that is bigger and more capable.

Contact an Air Conditioning Repair Service

For best results, contact professional help when you first notice your frozen coils and an expert may be able to help. They can find the problem quickly instead of forcing you to fix it through trial and error while the temperature inside your house starts to rise.
