Why There’s Ice on Your Heat Pump

Finding ice on your heat pump may seem like an indication that the system is working properly. Unfortunately, this is not the case. If ice is forming on your heat pump, you actually have a pretty big problem. If the source of the ice is not dealt with, it can actually cause the entire system to breakdown. Let’s take a look at why ice actually forms on your heat pump and the problems it can cause.

Evaporator Coil Issues

Your heat pump uses a part called the evaporator coil to siphon thermal energy from the surrounding area. This is how the heat pump cools your home. There are two things that happen when the evaporator coil siphons heat from the air being circulated over it. First, the coil itself gets very cold. Second, condensation forms on the coil as the air is cooled past the dew point. The only reason that the coil does not freeze is because of the constant flow of warm air over it. If that air flow is cut off for whatever reason, however, the condensate will freeze and form ice.

Problems Ice Causes

First and foremost, ice on the evaporator coil prevents the coil from siphoning any more heat from your home’s air. This more or less cripples the heat pump by itself. Second, if not removed as soon as possible the weight of the ice can cause the coil to permanently warp. Third, if allowed to progress for long enough, the ice can actually spread to other parts of the heat pump and affect them as well. This is why it is so important to address heat pump ice as quickly as possible.
