Furnace vs Boiler in Anderson County, South Carolina
When a furnace makes sense
If your home already has ductwork, a furnace makes sense here. It only has to cover about five months of real heating, and winter nights averaging 34°F are not the kind of extreme cold that changes the math. Just over half of homes in this region heat with a furnace, and it pairs with the same ducts your air conditioning uses.
When a boiler makes sense
A boiler suits a home that already has radiators or in-floor pipes instead of ducts, or an owner who wants the steadier heat that comes with them. It runs about 5% cheaper here on gas, which matters more the longer your winters run, though at five months a year that gap stays modest. It is a less common choice in this region, so it fits best where the house is already built for it.
