3 Reasons Your HVAC System Coils Freeze

There could be many reasons why your air conditioner’s coils are freezing. Dirty air filters and blocked condensate lines are two of the most common causes. One of our professional contractors can inspect your system, determine the source of the problem, and make any necessary repairs. Keeping your unit’s coils from freezing can lower your cooling expenses and improve the energy efficiency of your Tyrone, Georgia, home.

Dirty Air Filter

The cleaner the air filter, the easier your air conditioner can cool your home. A dirty air filter, on the other hand, constricts airflow and makes it more difficult for air to circulate around the coils. When air can’t circulate, the coils get too cold and freeze. By changing the air filter regularly, you can ensure that air is able to fully circulate around the coils.

Broken Fan

Even if your air conditioner has a clean air filter, the coils need air to keep them from freezing. If the fan is broken, it can’t circulate air. Dirty blades can also inhibit airflow and cause the coils to freeze. If you think the fan is broken, contact one of our HVAC professionals as soon as possible.

Malfunctioning Thermostat

When the thermostat can’t correctly sense the temperature inside your home, it will cause the air conditioner to run constantly. As it runs, the lines will become colder and colder and, eventually, the coils will freeze. One of our professional HVAC specialists can inspect the system and the thermostat to ensure that everything is working properly. This not only prevents the coils from freezing but also improves your unit’s cooling efficiency.

Blocked Condensate Lines

Your HVAC unit has condensate lines that ensure that excess moisture is draining properly. When these lines become blocked, moisture builds up around the coils and causes them to freeze. Preventive maintenance is very important for making sure that the condensate lines don’t become blocked.
