What Causes Your Heat Pump to Freeze Unnecessarily?

What Causes Your Heat Pump to Freeze Unnecessarily?

q qq qq Leave a Commentq

When your home’s heating and cooling system fails to keep it at an appropriate temperature, it’s often due to a frozen heat pump. Unfortunately, a frozen heat pump can cause extensive damage to your home, costing you time and money to repair. What can you do to prevent your heat pump from freezing? Here are some ductless heat pump installation tips from the pros.

Airflow is Not Sufficient

When the airflow through your ductless heat pump is insufficient, the heat pump can become frozen. Several factors, such as low HVAC system efficiency, inadequate ductwork, or a clogged or dirty heat pump condenser, can cause low airflow.

Dripping Water

Water can drip down the side of the unit and accumulate on the coils, leading to a frozen heat pump. If the water leaks into the unit through the condenser, this can also lead to a frozen heat pump.

Compressor Issues

Compressors can also freeze if they are not properly maintained. A frozen compressor can cause the unit to overheat and ultimately freeze.

Slab Settling

If the unit sits on a sloped surface, water can accumulate on the coil’s surface, leading to a frozen heat pump.

Defrost Mode Failure

If the defrost mode fails, the unit will continue to run and thaw out the coils over time, potentially leading to a frozen heat pump.

Ductless Heat Pump Maintenance Tips

Keep Vents Clear

Ensure all vents are clear of obstructions to allow adequate airflow through the unit.

Change the Air Filter

Regularly change the air filter on a ductless heat pump to help maintain consistent airflow and to reduce the chances of a frozen heat pump.

Keep the Pump Clear of Debris

Ensure the unit is kept clean to reduce the chances of debris accumulating on the coils and later freezing.

Relevel Your Heat Pump Slab

If your heat pump sits on a sloped surface, it may need to be leveled to prevent the unit from becoming frozen.
