3 Causes of a Heat Pump Blowing Warm Air in Cooling Mode

The spring and summer heat can be frustrating if your HVAC system is acting up. When this happens, your heat pump will not respond correctly to the set parameters in the system. Here are three common causes of a Margate, FL heat pump blowing warm air despite being in cooling mode.

1. Wrong Settings on the Thermostat

One of the most common reasons for the heat pump to blow warm air in cool mode is incorrect thermostat settings. This happens when you erroneously set the thermostat yourself. Another reason for this is when someone tampers with the thermostat after you have set it to cooling mode.

When you notice your heat pump is blowing warm air when you are certain you have set it to cooling mode, the first thing to do is to check the settings to confirm that they are correct. Once you have established that the settings are correct, consider calling an expert to inspect your HVAC system for repair or damage.

2. Dirty Air Filter

The air filter of your HVAC system is among the components that require frequent maintenance and regular check-ups. When your heat pump is not responding accordingly, consider opening the air filter enclosure and checking for the accumulation of dust.

3. Faulty Reversing Valves

There are instances when the reversing valves get stuck and cause the heat pump to stay on heating mode even after switching to cooling mode. This is due to a faulty valve or damaged switching mechanism. When this happens, it is important to hire an HVAC expert to check and recommend the necessary repairs.

Replacing the damaged reversing valve will help resolve this situation. However, routine maintenance is important for the entire system to ensure other related mechanisms are functional.
