Why Your Heat Pump Won’t Send Out Heated Air


The point of getting a heat pump is so that your home can enjoy both heating and cooling from a single system. There is no reason to purchase a heat pump and only use it for one job—that’s a waste of money and potential!

Sometimes, however, your heat pump might end up wasting its potential all on its own. You set the thermostat to provide the house with a comfortable warm temperature on a cool day, and the heat pump turns on, you can hear the blower fan and feel the air coming from the vents … except the air from the vents is either room temperature air or cool air. What’s wrong? Does this call for heating repair in Conway, AR?

Some small things to consider first

Before you call us to send a technician to check out your heat pump, there are some checks you can make yourself. Basic troubleshooting. First, recheck the thermostat. You may have it accidentally set to the wrong mode. Sometimes “auto” mode will keep the heat pump from either heating or cooling. For a programmable thermostat, you may have input the wrong program. 

Once you’ve determined the thermostat is fine, check on the air filter for the HVAC system. If it’s clogged, it can cause a serious decline in the heat pump’s heating ability. Also look around the outdoor cabinet to see if something is blocking it, such as tree branches or shrubs. 

The more serious troubles 

You’ve made the checks, and the heat pump is still either sending out cool or room temperature air. What else could be wrong?

If the heat pump is stuck in cooling mode, the most likely cause is that the reversing valve is broken. This is the component that changes the direction of refrigerant flow through the heat pump, shifting it between heating and cooling mode. If it becomes stuck, the heat pump will be trapped in one of its modes. The problem could also be a lost signal from the thermostat: if it loses its connection to the reversing valve, it can’t tell the heat pump to change modes. Technicians can replace the reversing valve or repair the thermostat.

If the air is neither hot nor cold, there might be trouble with the compressor or leaking refrigerant. These are serious problems that can require expensive repairs if they are not corrected soon. It’s also possible that (again) a malfunctioning thermostat is at fault and isn’t registering that the house needs either heating or cooling.
