A heat pump system is provided having an exterior coil, an exterior fan and fan motor, an interior blower, a reversing valve, and an auxiliary heater element. A method for defrosting the exterior coil includes the steps of initiating a defrost cycle by activating the auxiliary heater element for a period of time, and thereafter deactivating the exterior fan and fan motor and shifting the reversing valve to a cooling mode, After the defrost cycle has ended, the reversing valve is shifted to a heating mode, the exterior fan and fan motor are activated, and the auxiliary heater element is deactivated. The heat pump system results in less "cold blow" during the defrost cycle of a typical heat pump system, by providing additional heat to the interior space and interior duct work before tine system is operated in a cooling mode to defrost the exterior coil.
