Why Is My Heat Pump Freezing Up in Charlotte, NC?

March 3, 2024

There are many things that could cause your heat pump to freeze during the colder months in Charlotte, NC. Pinpointing the specific cause will make it much easier for service technicians to assist you, so let’s go over the most common problems.

Low Refrigerant

Refrigerant can sometimes leak due to component failures or improper fitting. The refrigerant tank may even have a puncture in some cases, which will create freezing. If you hear the pipes making rattling sounds, this can be a sign that something is wrong with the heat pump.

Blower Motor Malfunction

Sometimes, the blower motor may slow down due to wear over time, and this can cause it to stop periodically. This will interfere with normal operation and can lead to a freeze-up.

Dirty Evaporator Coil

If the evaporator coil is full of dirt, it won’t transfer heat as well as it should. This can cause problems with normal airflow and lead to freezing. Pouring some warm water on the coils can melt ice buildup.

Dirty Fan Blades

The blower’s fan blades can also become dirty after a while, preventing sufficient air from blowing over the coils. There may also be some ice buildup due to trapped moisture. This can compromise the system’s circulation and cause it to freeze.

Clogged Air Filter

If the indoor air filter has not had any maintenance in a while, it can accumulate dust and debris, which will hinder the airflow. The filter should be switched out once you notice a buildup to maintain a well-functioning system. Every three months is a good time to switch.
