Furnace vs Boiler in Winnebago County, Illinois
When a furnace makes sense
If your house already has ducts, a furnace is the straightforward choice. Ducts are common across this region, and that's the equipment a furnace is built to use. It heats fast, which matters when winter nights here average 16°F for months at a stretch.
When a boiler makes sense
If your home heats through radiators or in-floor pipes instead of ducts, a boiler is the machine built for that. It runs about 5% cheaper to operate here than a furnace, and with around 8 months of heating a year, that gap adds up. It's the right call mainly for a house that isn't set up for ductwork in the first place.
