5 Reasons Your Heat Pump May Freeze Over in Moseley, VA

A heat pump that freezes over compromises your home’s comfort. Read on to learn about five issues that can cause your home’s heat pump to become frozen over in Moseley, VA.

1. Clogged Air Filters

You can avoid this common heat pump issue by changing the air filters in your heating and cooling system every two to three months. Filters that get clogged with debris like pet hair, dust and pollen compromise airflow and trap moisture. After you change the filters, you should turn on the system’s heat to thaw out the heat pump.

2. Low Refrigerant Level

When your AC runs low on refrigerant, it can also cause the heat pump to freeze. Your air conditioner might make rattling noises when it runs low on refrigerant. You should act quickly and hire an HVAC technician to refill it and check for leaks.

3. Dirty Evaporator Coil

Dirty evaporator coils compromise heat pump function. Evaporator coils remove heat from the air and cool air with refrigerant running through copper tubes in the AC. You can keep them clean and protect your heat pump’s operation by having a technician in Moseley, VA maintain your system at least once a year.

4. Dirty Fan Blades

Like the evaporator coils, the fan blades can accumulate dirt and dust. They require regular cleaning so that they don’t trap moisture and freeze the heat pump. An HVAC technician can clean the fan blades as part of the heating and cooling system’s routine maintenance.

5. Damaged Blower Motor

A blower motor that malfunctions causes freezing. You can tell it needs repairs or replacing if it runs at a reduced speed, starts and stops intermittently or doesn’t turn on. An HVAC technician can repair or replace this part to prevent your heat pump from freezing over.
