A heat pump is one of the easiest HVAC systems to control. When you want to change from cooling mode to heating mode, all you have to do is set the thermostat temperature lower than the current temperature of the house. This signals the heat pump to change the direction it circulates its refrigerant, and this switches it over to begin moving heat into the house. The heat pump doesn’t operate much differently in the two modes (it’s still evaporating refrigerant in one coil and condensing it in the other), so it’s an easy change to make.
Except right now, for some reason, that change hasn’t happened for your house, even though it’s the season for it. If you have a heat pump that isn’t sending out heat or is actually sending out cold air, you may have a problem that requires heating repairs in McDonough, GA. Let’s take a closer look at the possible causes.
