the heat, as is the case with more traditional furnace designs.
During summer, the heat pump reverses the flow of the heat-
absorbing refrigerant to become an energy-efficient, central air
conditioner. Excess heat energy inside the home is absorbed
by the refrigerant and exhausted outside the building.
