Furnace vs Boiler in Brown County, South Dakota
When a furnace makes sense
If your house already has ductwork, a furnace is the straightforward choice. It's what most homes in this region run on, and at 6°F on a winter night you want a system already built for your house, not one you're retrofitting. Furnaces heat through the same ducts you likely use for central air, so there's nothing new to install to get warm air moving room to room.
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 than a furnace here, which matters over a heating season that stretches 9 months. Just know it only heats, so you'd still need another way to cool the house come summer.
