Why is my Heat Pump Blowing Cool Air?

One of the most frustrating problems is when your heat pump begins blowing cold or cool air instead of warm air. This problem occurs more often than you may think. It can be caused by a number of issues. Below is a list of answers to the question: Why is my heat pump blowing cool air? Discover the most common causes, and what you can do to fix it…

Why Is My Heat Pump Blowing Cool Air?

The compressor is not operating properly.

If the compressor in your system is not operating properly, your heat pump will not be able to adequately remove heat from the air to carry indoors. A heat pump essentially works as an air conditioner in cold weather. In an air conditioner, the compressor cools down the coolant that is used to draw the heat from the air, removing heat from the walls and interior of a building and pumping cool air back into it. In a heat pump, the process is reversed. Heat is drawn from the air outside and then blown into the structure, rather than drawing air from the structure’s interior. If the compressor is not properly keeping the coolant cool, the system cannot efficiently produce warm air.

The heat pump is frozen.

In extremely cold temperatures or extended periods of cold weather, the outdoor unit may be frozen and covered with ice. The unit may have to be thawed.

The defroster is running.

Your heat pump is equipped with a defroster that comes on once every hour to prevent the buildup of ice. This causes the pump to blow cold air into your building for a short period of time. It is not something that you should be concerned about. If the system is running and your fan is not blowing, it simply means the heat pump is defrosting and should begin blowing warm air again soon.

There may be no problem at all.

Sometimes people assume there is a problem with their heat pump when in fact there is no problem at all. Many buildings have furnaces that rely on short blasts of hot air to keep the interior heated. Heat pumps, however, work by supplying a steady stream of warm air to regulate the temperature throughout the building. If you are used to having a furnace in your building, you may have to deal with a short adjustment period.
