Furnace vs Boiler in Codington County, South Dakota
When a furnace makes sense
If your house already has ductwork, a furnace is the straightforward choice, and across this region most homes are set up that way. Those same ducts carry cooling too, so a furnace keeps that option open if you add central air later. With nine months of heating a year and winter nights averaging 6°F, you want a system matched to what your house already has in place.
When a boiler makes sense
A boiler makes sense if your home heats through radiators or in-floor pipes rather than ducts. It runs about 5% cheaper here than a furnace, and over nine months of heating a year that difference adds up. It will not move air, so if you want central air down the road, that would mean a separate system.
