The two main phases of heat pump operations are the heating and cooling cycles. Heat pumps work in much the same way as your refrigerator does, converting heat and redistributing this heat to the outside or indoors as you desire. There is a third phase which is the defrost cycle. Frost forms on the surface of the coil under some conditions depending upon temperature and relative humidity. This layer of frost that forms on the coils interferes with the efficiency of the heat pump. The frost must be removed by putting the pump through a defrost cycle.
