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

Operating a heat pump is an efficient way to heat and cool homes in moderate to warm climates like Surprise, AZ. If you’ve recently switched your heat pump to heating mode only to feel cold air blowing out, you’re probably wondering what’s wrong. Here are three reasons your heat pump may blow cold air while in heating mode:

Thermostat Settings Need Adjustment

If you want your system to blow only when it’s heating your home, set your thermostat to “auto” instead of “on.” The “on” setting keeps the fan blowing constantly, which means that it’ll blow cold air when the system isn’t producing heat.

Dirt and Dust on Condenser Coils

Another common reason for a heat pump blowing cold air is dirty condenser coils. Dust, dirt and debris on your outdoor unit make it difficult for the coils to collect and move heat. Fine dust and dirt can hide inside the condenser, so your coils can still be dirty even if they look fine. Regular maintenance services are important to keep your HVAC system clean and working efficiently. We recommend scheduling two tuneups per year.

Faulty or Damaged Reversing Valve

The reversing valve is one of your heat pump’s most essential components that allows it to switch between heating and cooling modes. A failing reversing valve can cause your system to blow cold air in heating mode. If you suspect your reversing valve needs replacing, a heating repair service technician will need to assess the problem and determine whether to fix or replace it.
