Furnace vs Boiler in Story County, Iowa

When a furnace makes sense

If your house already has ductwork, a furnace is the straightforward choice. That same ductwork can carry air conditioning too, so you are not paying to install a second system for summer. With winter nights averaging 14°F and heat needed about eight months of the year, you want a system that can push warm air through the house fast, and a furnace does that well.

When a boiler makes sense

If your home already heats through radiators or in-floor pipes, a boiler is the natural fit. It runs about 5% cheaper than a furnace at Iowa prices, which adds up over eight months of heating a year. The tradeoff is that a boiler only heats, so you would need a separate system for cooling.
