Furnace vs Boiler in Dallas County, Iowa

When a furnace makes sense

If your house already has ductwork, a furnace is the straightforward choice. Nights here average 15°F for months at a stretch, and a furnace pushes that heat through the ducts your home most likely already has, with nothing extra to install. Across this region, most homes are already set up this way.

When a boiler makes sense

A boiler makes sense if your home heats through radiators or in-floor pipes rather than ducts, or if you are set on that kind of heat. It runs about 5% cheaper here than a furnace, which matters over eight months of heating a year. Just know it will not do anything for cooling, so you would still need a separate way to handle summer.
