Furnace vs Boiler in Linn County, Iowa
When a furnace makes sense
If your house already has ductwork, a furnace is the straightforward choice. That same duct system can carry air conditioning too, so you are not paying for a separate setup to keep the house cool in summer. With winter nights averaging 15°F here, you want a system that can push heat fast, and a furnace does that well.
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 converting to forced air would mean adding ductwork you don't have. Boiler heat runs about 5% cheaper here than a furnace, which adds up over the 8 months a year this county needs heat. Just know a boiler won't handle cooling, so you would still need a separate system for summer.
