Should I choose a heat pump, or a furnace?A heat pump is an air conditioner equipped with a reversing valve so it can run refrigerant in reverse, thus heating your home. Conversely, a furnace burns fuel in order to heat your home.
Typically, furnaces are used more commonly than heat pumps, and are used almost exclusively in harsh, cold weather climates.
Heat pumps are typically seen in mild, coastal climates like the Southern California or Florida coastlines. Although they are not designed for harsh winters, they are sometimes used when access to natural gas or propane is impossible, and are then fitted with electric strip heat to supplement them on colder days.
