Why Does My Heat Pump Blow Hot Air in Cooling Mode?

When your heat pump unexpectedly circulates hot air on its cooling setting, it’s imperative to identify the root cause to restore optimal performance. Here are four reasons your heat pump might blow hot air while set to cool mode in your Dearing, GA, home:

Incorrect Thermostat Settings

Before thinking your system might have broken, we recommend checking your thermostat settings. Ensure the thermostat is set to “cool” and not “heat.” Modern thermostats sometimes have various modes and programmable settings. If incorrectly set, it can result in the system working in the wrong mode.

Blocked or Dirty Coils

If these coils become dirty or blocked due to debris, dust or even biological contaminants, they become less efficient in transferring heat. As a result, the system might end up circulating warm air. Regular heat pump maintenance can prevent such issues and keep your system running efficiently.

Refrigerant Issues

If your system is low on refrigerant or there’s a leak, it may struggle to absorb enough heat from inside your home to release outside, causing it to blow warmer air. Not only will this make your home uncomfortable, but it can increase your energy bills. It can also damage the compressor if left unchecked.

Reversing Valve Malfunction

The reversing valve is responsible for changing the flow direction of the refrigerant, allowing the system to switch between heating and cooling modes. If this valve malfunctions or becomes stuck, the heat pump might get trapped in the heating mode even when you want it to cool. If you suspect this is the issue, schedule a repair service to address the problem promptly.
