Furnace vs Boiler in Outagamie County, Wisconsin

When a furnace makes sense

If your house already has ductwork, a furnace is the straightforward choice. It ties into what's already there instead of asking you to add radiators or in-floor pipes. Nine months of the year need heat here, with winter nights averaging 13°F, and a furnace run on gas is built for that kind of steady demand.

When a boiler makes sense

If your home heats through radiators or in-floor pipes rather than ducts, a boiler fits that setup without ductwork to install. It also runs about 5% cheaper here than a furnace does. Fewer homes in this region use one, so it's worth knowing your contractor has serviced a boiler before.
