Furnace vs Boiler in Milwaukee County, Wisconsin
When a furnace makes sense
If your house already has ductwork, a furnace is the straightforward choice. That same ductwork can carry central air conditioning too, so you get both from one system. With eight months of heating a year and nights averaging 18°F, you want a system that matches what most homes here already have in place.
When a boiler makes sense
A boiler makes sense if your home is set up with radiators or in-floor pipes rather than ducts. It runs about 5% cheaper to operate here than a furnace, which adds up over eight months of heating a year. Keep in mind it heats only, so you would need a separate way to cool the house in summer.
