Heat pumps are air conditioners that can operate in reverse to remove heat and add warmth to indoor spaces. Like an air conditioner, a heat pump has dual copper lines that connect its indoor coil with an outdoor unit. The refrigerant flows through the lines in one direction on a closed circuit to remove heat from indoor air.
A heat pump works the same way. However, the equipment can reverse the refrigerant’s flow to make the outside unit blow out cold air and heat the indoor coil. With a heat pump, you won’t need a separate air conditioner and furnace because the appliance performs both functions.
