You’ve switched the heat pump to cooling mode to prepare for the summer in West Melbourne, FL. But during the initial run, all you felt was warm air. There are many explanations why a heat pump heats in cooling mode.
Reversing Valve Malfunction
The reversing valve has the job of switching the system from heating to cooling mode and vice versa, so check this component first for any faulty parts. Specifically, the solenoid coil inside can become defective, sometimes getting burned out after electrical surges. You’ll be able to spot the reversing valve in the outside unit called the compressor.
Bad wiring in the thermostat can prevent the heat pump from kicking into cooling mode. Other times, you simply may not have switched the settings on the thermostat. You must have the thermostat to Cool as well as On or Auto mode; don’t put it on Fan mode.
Dirty Coils or Filter
Coil cleaning and filter replacement form the backbone of any maintenance plan because they can do much to improve heating/cooling efficiency. For their part, homeowners should take on the filter replacement every 90 days. Dirty coils and clogged filters will hinder the transfer of heat out of your home, which results in lukewarm air and the feeling that the heat pump is really in heating mode.
You’ll get the same impression if your heat pump lacks the refrigerant necessary to absorb heat from your home and release it outside. The air will remain lukewarm. Never attempt DIY refrigerant repairs. Schedule professional heat pump repairs.
