If your evaporator coil is freezing, it’s important to find out why and to take action. Here are five possible reasons your evaporator coil in Clarksburg, MD, is freezing up.
Lack of Airflow
When the air can’t flow freely over the coils, the temperature drops and moisture condenses on the coils. This condensed moisture then freezes, causing the coils to become covered in ice. If you notice that your evaporator coil is beginning to freeze, be sure to check for any blockages such as damaged ductwork that may be preventing proper airflow.
Dirty Air Filter
The air filter’s job is to keep dirt, dust and other airborne contaminants out of the HVAC system. When the filter clogs, it restricts the airflow to the evaporator coil. This may cause the coil to ice up because it isn’t getting enough warmth from the air flowing over it.
When the refrigerant is low, the coils can’t absorb enough heat, and the air doesn’t get cooled properly. As a result, the coils start to freeze. You can prevent this by making sure that the coils are clean and that there’s enough refrigerant, or you can try turning up the temperature on your thermostat since this will help the coils to absorb more heat and prevent them from freezing.
The drainpipe is responsible for carrying away any water that condenses on the evaporator coil. If the pipe becomes blocked, the water will back up and eventually cause the coil to freeze. AC maintenance is essential to prevent this from happening.
Low Outdoor Temperature
When the temperature outside is low, the AC unit’s evaporator coils can’t absorb enough heat, and this causes them to freeze. AC units that are not properly maintained are more likely to experience this problem.
