Heat Pump

Some of the calls we receive in the winter are customers telling us their outside unit is smoking or their unit is blowing cold air.

When the outside air temperature drops low enough depending on the dew point & humidity, the outside unit may ice up. The heat pumps have a sensor that will then tell the unit to go into the defrost mode. When this occurs, the outside unit switches over to air conditioning to defrost the ice and the outdoor fan shuts down.

The auxiliary heat strips in the indoor unit come on to produce heat. This may then feel like the air conditioning is on and you may see steam coming from the outdoor unit. Once the hot gases, circulating through the outdoor coil, melt the ice, the system will revert back to the normal heating cycle.

‚ÄčThis is a normal function of a heat pump system. If you have any questions or doubts please don't hesitate to call or e-mail us.
