Furnace vs Boiler in Stearns County, Minnesota

When a furnace makes sense

If your house already has ductwork, a furnace is the straightforward choice. It ties into what's already there, and with nine months of heating season and nights averaging 6°F, you want a system that moves a lot of heat fast. Ducts also mean you can add central air later without tearing into walls.

When a boiler makes sense

If your home heats through radiators or in-floor pipes rather than ducts, a boiler is the natural fit, since a furnace would mean adding ductwork it doesn't have. Boiler heat runs about 5% cheaper here at Minnesota gas prices, which adds up over a nine-month heating season. It won't provide central air, so if you want cooling from the same ductwork, that's a separate system either way.
