3 Reasons a Heat Pump Blows Cold Air in Heating Mode

Heat pumps have become increasingly popular due to their incredible dependability, efficiency and cost-effectiveness. But even with such a vital unit in your Rutledge, TN, home, you can still encounter some problems with it. If your heat pump starts blowing cold air while in heating mode, it could be a result of the following reasons:

Problem With Your Heat Pump

Heat pumps can fail because of a lack of maintenance, broken parts or human error. Specific examples include the following:

  • Low refrigerant levels.
  • Failing or broken reverse valve.
  • Fan set to ON instead of AUTO.

Any of the above issues can make your heat pump blow cold air. Fortunately, you can rely on our experienced heating repair team to fix your unit.

Heat Pump is in Defrost Mode

Most heat pumps function as reversed air conditioners. In case of ice buildup on the outdoor coils of your unit, the pump goes into defrost mode. This enables the equipment to thaw the frozen coils because it’s difficult to remove the ice formations manually.

Since defrost mode is the same as switching to cooling mode, your heat pump will blow cool air into your home. If you notice the outdoor unit blowing steam and the fan stops spinning, it’s undergoing the defrost cycle.

Likely Blowing Slightly Cooler Air

Note that heat pumps generate warm air that’s 90 degrees. By the time it circulates through the system and reaches you, it’s cooler than that. Since your average body temperature is 98.6 degrees, you may feel like the air coming from your vents feels cool.
