Inside a 3 ton air handler, refrigerant flows through the coil to absorb or release heat while the blower pushes conditioned air into your ducts. With a heat pump it handles both heating and cooling; add an electric heat kit and it provides backup heat on cold days or primary heat in an all-electric home.

Its coil exchanges heat with refrigerant from the outdoor unit while its blower moves air through the ducts. With a heat pump it does both heating and cooling; an added electric heat kit provides backup or primary heat.
Yes, with electric heat kits it can be the primary heat source in an all-electric home, though a heat pump paired with a smaller backup strip is usually more efficient.
