Why Is My Heat Pump in Parrish, FL, Freezing Up?

Heat pumps are popular HVAC options for heating and cooling, thanks to their versatility, durability and energy efficiency. However, they can develop problems. If your heat pump in Parrish, FL, keeps freezing up, you’re probably dealing with at least one of these problems:

Faulty Defrost Cycle

Your heat pump should occasionally go into a defrost cycle. This cycle allows it to melt any frost and ice buildup that accumulates on the coils. When this cycle doesn’t start or fails to run for long enough periods, ice builds up on those outdoor coils.

When ice builds up on the coils, it makes it impossible for your heat pump to heat or cool your home adequately. It can also place added strain on the system, leading to more frequent heat pump repairs and reduced energy efficiency.

Low Refrigerant Levels

Your heat pump relies on a chemical called refrigerant to aid in heat exchange. When any of the tiny tubes that carry this refrigerant through the system suffer damage, you’ll have a refrigerant leak.

The refrigerant’s job is to absorb and expel heat. When refrigerant levels are low, ice can form on your coils. This problem requires professional repair, since handling refrigerant without training is unsafe.

Restricted Airflow

Heat pumps rely on a steady stream of air passing over the evaporator coil. When you have clogged air filters or blocked vents, the system cannot get the air it needs. This can lead to ice forming on your evaporator coils and spreading to other components.

Fortunately, changing your air filters is one of the easiest maintenance tasks that you can handle on your own. It’s a good idea to change them every 30 to 90 days. Doing so also promotes healthy indoor air quality.

When you see ice on your heat pump, it’s a good idea to call for professional help. Contact All American Heating & Cooling for professional HVAC services, including heat pump repairs.
