Why Does My Heat Pump Blow Cool Air in Heating Mode?

During colder months in Florence, SC, you’ll likely need to use the heating mode on your heat pump regularly to stay warm in your home. Sometimes, though, something interferes with its operation. Read further to learn about some common heat pump issues that can cause your system to blow cool air while in heating mode.

Frozen Condenser Coil

During the winter, the temperature in our town seldom dips below freezing. However, there are certain situations where the outdoor condenser coil could freeze. One of those situations is when there’s dirt or other debris inside the outdoor unit.

That dirt can affect the condenser coil. When that happens, the condenser coil can freeze even if the outdoor temperature is above freezing.

Refrigerant Leak

Heat pumps rely on refrigerant to transfer heat into and out of your home, depending on its settings. If that process encounters problems, your heat pump could blow cool air when it should be blowing warm air. You may notice hissing or bubbling noises as well.

Malfunctioning Reversing Valve

The reversing valve helps change the heat pump’s mode from heating to cooling. If your reversing valve gets stuck or otherwise malfunctions, your heat pump could wind up staying in cooling mode. These kinds of heat pump issues require repair service by a professional technician.

Recent Upgrade

If you’ve recently changed from a furnace to a heat pump, then the air coming out of the vents will possibly seem cooler than what you previously experienced. Heat pumps use air that is slightly cooler from the environment to heat your home, as opposed to furnaces, which generate their own heat at a higher temperature.
