Why Is My Heat Pump Freezing Up in North Fort Myers, FL?

A frozen heat pump in your North Fort Myers, FL, home means you may not get the cooling comfort you need. If your system freezes, it’s important to understand the cause and know what you can do about it. Read on to learn more about some common causes of a frozen heat pump.

Dirty Air Filter

With a forced-air heat pump, a heating and cooling air filter clogged with dust and debris can significantly restrict airflow. Without enough warm air blowing over the coils, the condensation on them can freeze. Change your air filter regularly, about every two to three months, to avoid clogging.

Low Refrigerant

Refrigerant lets your heat pump produce conditioned air by enabling heat transfer. When the refrigerant is too low, it can’t absorb enough heat. This can then cause its coils to freeze up.

Dirty Coils

Heat transfer occurs in the condenser coils of your system. If these coils become excessively covered in dust and dirt, these contaminants can act as insulation and prevent proper heat transfer. The refrigerant stays abnormally cold, and condensation on the coils can freeze.

Outdoor Temperature

If you’re trying to cool your home, make sure the outside temperature is above 60 degrees. Running the heat pump when temperatures drop too low outside can result in frozen coils. Rather than turn on the system, open your windows for fresh air and a cool breeze instead.

When your heating and cooling system freezes up, you shouldn’t expect an ideal temperature in your house. Frozen coils can also lead to stress and wear on the pump, damaging various parts of your system.
