Furnace vs Boiler in Davison County, South Dakota

When a furnace makes sense

If your house already has ductwork, a furnace is the straightforward choice. Most homes in this region were built with ducts in place, and a furnace uses that system as is. It runs on natural gas and pushes heat fast when nights sit at 11°F, which matters for eight months of the year here.

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 to operate at South Dakota gas prices, which adds up over an eight-month heating season. Where there is no ductwork to work with, it heats the space directly without needing any added.
