My Heat Pump Is Not Blowing Hot Air

Posted on: December 1, 2015

Is your heat pump blowing cold air instead of warm? This is a common problem that can be caused by several different issues with your heat pump unit. 

The most common causes for your heat pump not blowing hot air are:

Heat Pump Compressor Not Operating

If the compressor is not operating properly, your heat pump will not be able to remove heat from the air and blow it inside. Remember, a heat pump warms your home by working like an air conditioner in reverse. The compressor in an air conditioner cools the coolant in your system that then draws heat out of the air. In the summer, the heat is removed from the interior of your home and cool air returned, but in the winter, the process is reversed. Heat is drawn from the air outside and blown into your home. If the compressor is not cooling the coolant, your system will not be able to produce warm air.

If your compressor is broken, you will need the assistance of a heating and cooling repair professional to get it working again.

Heat Pump Is Frozen

If temperatures outside are very cold, it is possible that the outdoor unit is frozen and covered in ice. This is rare, especially here in Southern California, but if temperatures are below freezing and moisture is present, it never hurts to look. If it is indeed frozen, try removing the ice from the system and see if that helps.

Defroster Is Running

Approximately every hour, your heat pumps 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 heat again.

There Is Nothing Wrong At All

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, they supply a steady stream of warm air to regulate your home’s temperature. If you are used to the heat of a furnace, there may be an adjustment period for you. It is common for air from a heat pump to feel lukewarm or even cool to the touch, but this air is, in fact, heated air that will allow you to keep your home warm and comfortable.
