When you switch your heat pump from heating to cooling during spring, you expect a cool burst of air from your vents. When that doesn’t happen, a few things could be wrong. Let’s explore what can cause your heat pump in Sun City, AZ, to continue heating even after you’ve switched to cooling for the warmer weather.
Faulty Thermostat
When you receive hot air instead of cold air, the first thing to do is check the thermostat. Make sure your thermostat is set to cooling mode and adjust the temperature slightly lower to check for cold air on the next cycle. If that doesn’t help, your device may be sending incorrect signals to the heat pump.
Frozen Coils
A number of factors can cause your coils to freeze, causing your heat pump to stop producing cold air. If you suspect frozen coils, turn off the system and give it time to thaw. For repeated issues with frozen heat pump coils, ask our service techs to investigate the underlying issue.
Clogged Filters
Dirty air filters hinder airflow from your cooling system and make your heat pump work harder to overcome the obstacle. The pump may then stop producing cold air, leaving you with warmth blowing from the vents. Be sure to check air filters often and change or clean them every one to three months, depending on your heat pump model.
Damaged Valves
Valves inside your heat pump direct the movement of refrigerant. If these valves malfunction, the pump may not get the refrigerant needed to produce cold air. In the event of valve malfunctions, you need professional repair services.
Your heat pump provides both heating and cooling and transitions between the two modes with a simple flip of a switch. However, if you don’t get cooling when you need it this spring, you may need professional help.
