The last thing anyone in Guyton, GA wants when temperatures drop is for their heat pump to start blowing cold air. This is a common problem that, luckily, has easy solutions. Let’s go over some common reasons why a heat pump blows cold air even though the heat is on.
Leaking Refrigerant
If refrigerant is leaking out of the heat pump, this will impair the it’s efficiency, causing it to produce cold air. Usually, this issue will require a technician to fix as a leak can indicate there are other issues with the heating system.
Outdoor Unit Is Dirty
Your heat pump normally pulls in air from outside the home, so if leaves, dirt or other debris clogs the outside unit, this can stop it from transferring heat properly. Now and then, it’s a good idea to clear up the area around the outdoor unit and have a professional clean the compressor as well.
Faulty Thermostat Wiring
If something is wrong with the thermostat’s wiring, this will result in HVAC issues. The thermostat terminal may not control the changeover valve properly anymore, which will cause it to stay in cooling mode. Reconnecting the wires is necessary in order for the thermostat’s settings to have an effect.
Reversing Valve Is Broken
If the reversing valve breaks, this will cause the refrigerant to stop flowing toward the evaporator coil. When this happens, the heat pump will start putting out cold air because it can’t switch into cooling mode like it normally would.
Fan Is On
If the fan is set to “on” rather than “auto” on the thermostat, then the heating system will keep putting out cold air even while it’s set to heat. Switching to auto will ensure that the it only blows out heated air.
