Furnace Troubleshooting: Heat Pump Not Blowing Hot Air

Is your heat pump blowing cold air instead of warm? This is a common problem that has various causes with your heat pump unit. Before you troubleshoot your heating pump, understand some of these common causes.

Heat Pump Compressor Not Operating

The compressor is the part of your heating system that circulates refrigerant that absorbs and releases heat as it travels between the indoor and outdoor units. Your compressor needs to cool the coolant to produce warm air. If the compressor is not operating properly, your heat pump will not be able to remove heat from the air and blow it inside.

Heat Pump Is Frozen

If temperatures outside are very cold, it is possible that the outdoor unit is frozen. This is rare, especially here in Southern California, but if there is moisture present and temperatures in or around your outdoor are below freezing, ice can build up and freeze your heat pump. Check your outdoor unit and if it is indeed frozen, try removing the ice from the system and see if that enables your heat pump to produce warm air.

Defroster Is Running

Approximately every hour, your heat pump’s defroster will turn on to prevent a buildup of ice. For a very short period of time, this will cause it to blow cold air into your home. If your system is running but the fan is not blowing, your heat pump is defrosting. There is no need for concern here—it will begin blowing warm air again.

There Is Nothing Wrong

Keep in mind, a heat pump is not a furnace. Heat pumps do not rely on short blasts of hot air to keep your home warm. Instead, your furnace supplies a steady stream of warm air to regulate your home’s temperature. It is common for air from a heat pump to feel lukewarm or even cool at times but this air is, in fact, heated air that will allow you to keep your home warm and comfortable.
