Why Is My Heat Pump Freezing Up in Louisville, KY?

Your Louisville, KY home’s heat pump provides cold air to help you stay comfortable as summer heats up the area. However, your system should never get so cold that it freezes. If you have a frozen heat pump, read on and learn about some of the possible causes so that you know what to do.

Clogged Air Filter

When your cooling system’s air filter becomes clogged with debris and dust, your system must work harder and longer to cool your home. This strenuous cycling can cause the system to freeze as it fails to bring the home’s temperature down. Change your air filter every three months to promote good airflow.

Dirty Condenser Coils

Your heat pump creates cold air and handles heat exchange inside the condenser coils. If these coils become coated with dust and dirt, the system may freeze and stop blowing cold air. Schedule HVAC maintenance annually so that our technicians can keep these coils clean and prevent excessive buildup on them.

Low Refrigerant Level

Refrigerant cycles repeatedly through your system to create conditioned air. Too little refrigerant usually indicates a leak. When refrigerant escapes the lines, it can cause other parts of the system to freeze.

Low Outdoor Temperature

Don’t use your HVAC system to cool your home if the outdoor temperature falls below 60 degrees Fahrenheit. Cooler temperatures outdoors can cause your system to freeze, resulting in damage to components and an absence of proper airflow. When the weather outside is milder, open windows to let fresh air into the house.

You should be able to rely on your heat pump for strong, efficient cooling all summer. However, if your pump freezes, you won’t get the cold air you need for home comfort. If you have repeated issues with a frozen heat pump, call Birkhead Co. today for trusted heat pump repairs in Louisville, KY.
