Why Your Heat Pump Will Only Blow Cold Air

When you have a heat pump installed in your Florida home, you do it because you want both heating and cooling for year-round comfort. If your heat pump starts to fail to do one of its two jobs—such as blowing only cold air during a time when you need heating—then you may have a serious problem with the unit that will require repairs from heat pump specialists.

We’ll go through some of the reasons your heat pump may seem to be stuck in cooling mode to help guide you toward a solution. Envirotech Air Quality Services is ready 24 hours a day to help you with any repairs you need in Wellington, FL for a heat pump.

Reasons for a heat pump to only cool

Let’s eliminate a simple possibility: the heat pump’s thermostat is set incorrectly. Check the thermostat to see if an error in programming has caused the heat pump to remain in cooling mode.

However, a thermostat can appear to have the correct setting, and yet have a malfunction that makes it send the wrong instructions to the heat pump. A miscalibration can lead to the thermostat sensing false temperature readings. A wiring problem can cause the thermostat to lose its connection to the heat pump entirely so that it cannot signal the heat pump to switch modes. Heating experts will get to the bottom of the problem and find a remedy.

The most common reason inside the heat pump itself for this problem is a malfunction with the reversing valve. This crucial component is attached to the refrigerant line and is responsible for changing the direction the refrigerant flows through the unit, and consequently the change from one mode to the other. If the reversing valve breaks, the unit will remain stuck in one mode. Only an expert repair technician can properly replace a broken reversing valve.

Bring in heating and cooling specialists

Heat pumps are not pieces of equipment that amateurs can repair using a printed-up guide from the Internet. You need professionals with the right training and the right equipment to assist you. If your heat pump remains in cooling mode, and nothing you do with the thermostat will correct it, you’ve reached the point where you need to call a heating and cooling contractor.
