Heat Pump Ice and the Problems it Creates

If you’re using a heat pump to keep cool today, you may notice ice forming on the inside unit. This may seem like a good thing, considering that the heat pump is supposed to be cooling the air in your home. However, it’s actually a serious problem that needs to be addressed as soon as possible. Read on to find out more about heat pump ice, and the problem is presents.

Why It Happens

When a heat pump is cooling your home, it evaporates refrigerant in a part called the evaporator coil to absorb thermal energy from the ducts. It then sends the refrigerant gas outside and condenses it, which releases the collected heat outside of the home. The air temperature around the evaporator coil is constantly dropping during this process, and condensation forms on it as the temperature drops past the dew point. If the flow of warm air from the ducts is ever interrupted, the condensate on the coil will eventually freeze and form ice.

The Problems

There are a few pretty serious problems that can occur thanks to heat pump ice. For one thing, the evaporator coil will be unable to siphon thermal energy from the air while it’s covered in ice. This will cause the output of your heat pump to drop significantly. The weight of the ice can also warp the coil, necessitating its replacement. If the ice is not cleaned off and the root problem solved, it can spread down the refrigerant line to other parts of the system. This will cause them to freeze over and breakdown. Eventually, the entire system can completely break down due to ice on the coil. If you see your heat pump icing over, call for repairs right away.
