Why Does My Heat Pump Freeze Up in Newberry, FL?

Here in Newberry, FL, winter temperatures drop to the 40s at night. You’ll need your heat pump working to remain comfortable. Freezing is a common problem for heat pumps, so read on to learn about a few reasons your heat pump could freeze.

Insufficient Airflow

Poor airflow interferes with the pressure inside the system. The lower pressure can cause excess moisture to form on the evaporator coil, and the heat transfer process lowers the temperature, causing the freezing.

Dirt Buildup on HVAC Coils

Speaking of the heat transfer process, dirt on the evaporator coil causes problems. When that happens, the system can’t reabsorb the water that forms as condensation, and that water can freeze. Debris in or on the outdoor condenser coil inhibits the heat absorption abilities of your heat pump, resulting in the outdoor unit freezing.

Low Refrigerant Level

Low refrigerant results from a leak, and the pressure reduction inside the evaporator coil has a similar effect as the low air pressure outside it. That can result in ice forming on the coil. Finding a refrigerant leak on a heat pump takes an expert’s eye.

Problems With the Defrost Cycle

Modern heat pumps have the ability to defrost themselves if they freeze. If yours freezes and stays frozen, then there could be a problem with the defrost board. Repairing the board requires an expert.

One of the things that can interfere with the defrost cycle is a faulty reversing valve. A malfunctioning valve can keep the defrost cycle from engaging correctly.
