Heat pumps are more adaptable in terms of providing indoor comfort since they can offer heat in the winter as well as operate as air conditioners in the summer. This implies that homeowners in hotter areas can use a heat pump system to heat and cool their homes. Furnaces, on the other hand, only supply heat, thus a separate air conditioning equipment is necessary to chill your home during the summer. Heat pumps are technically more energy efficient than air conditioners since they may transfer more energy than they use.
