During Fredericksburg, Stafford, Virginia winter months many heat pumps will need to go through a “defrost” cycle during operation.
In heating mode a heat pump extracts heat from the outside air and transfers it inside your premises to warm it. When the ambient temperature outside gets very cold (close to 0°C or below) the moisture in the air freezes on the outdoor unit’s heat exchanger as the fan blows the air across it. A defrost cycle is simply the system recognizing that ice has formed or begun to form and automatically fixing this.
