Why Does My Heat Pump Have Ice on It?

Frozen Ac Heat Pump Scaled 1 1

During winter, it is common for a thin layer of frost to gather on heat pump systems. If you’ve discovered that your heat pump is covered in a bit of ice, there is no need to worry.

What Causes Frost to Form on a Heat Pump?

When it is cold outside and your heat pump is set to heat your home, it is likely that your system will develop a little bit of frost. As the heat pump pulls air from outside into the home, the moisture in the air around the system will accumulate and become frost that clings to the system.

Frost also tends to form on the coils of heat pumps. When the heat pump generates heat, the refrigerant turns to gas and condenses when it reaches the coils. This condensation can create frost on the coils, which is totally normal. In fact, heat pumps are designed to activate a defrost cycle to take care of this frost.
