A furnace is a great choice for those who have access to natural gas, or have recently installed a new cooling system. A heat pump is a good option in homes that have no natural gas line, or those who are ready to replace both their heating and cooling systems. Because a heat pump operates most efficiently in climates where temperatures rarely fall below 40 degrees, in an area like Beaver County, homeowners who opt to install one may benefit from a supplemental source of heat during cold winter evenings.
