Heat Pump Iced Up During Winter?

Heat pumps will naturally ice-up in the winter, but will periodically go into a defrost cycle to de-ice the coils and keep the unit running efficiently. If the coils are blocked by ice, proper heat transfer between the refrigerant and the<br>outside air cannot occur. This can cause serious damage to your equipment.

  1. Heat Pump Iced Up During Winter? It’s normal for your heat pumps to ice up during the winter months. The entire coil might even be covered in frost or ice during cold weather conditions. However, it’s not normal for the entire unit to be covered in ice for an extended period of time. Heat pumps will naturally ice-up in the winter, but will periodically go into a defrost cycle to de-ice the coils and keep the unit running efficiently. If the coils are blocked by ice, proper heat transfer between the refrigerant and the outside air cannot occur. This can cause serious damage to your equipment. The Defrost Cycle Explained To prevent from icing up, heat pumps switch into air conditioning mode for a while until it unfreezes. This defrost mode only lasts 10-15 minutes, during which time heat strips start up to keep the air warm.
