Furnace vs Boiler in Dubuque County, Iowa
When a furnace makes sense
If your house already has ductwork, a furnace is the straightforward choice. Those same ducts can carry cool air in summer, so one system covers both jobs. Across this region, most homes are built around ducts like these, which is why a furnace tends to be the simpler fit.
When a boiler makes sense
If your home heats through radiators or pipes in the floor rather than vents, a boiler fits what's already there. That kind of heat tends to feel steadier through a cold night, and with winter nights here averaging 15°F, that steadiness is worth something. Heating with a boiler runs about 5% cheaper here than a furnace, though it won't move air for cooling, so you would need a separate system for that.
