Furnace vs Boiler in Saginaw County, Michigan
When a furnace makes sense
If your house already has ductwork, a furnace is the straightforward choice. Ducts also let you run central air conditioning off the same system, which matters once summer comes around. With winter nights here averaging 19°F, you want a furnace sized to keep up, and gas furnaces are built for exactly that kind of cold.
When a boiler makes sense
If your home heats through radiators or in-floor pipes rather than ducts, a boiler is the machine built for that. It runs about 5% cheaper than a furnace here, which adds up over eight months of heating a year. It won't move cooled air in the summer, so you would need a separate way to handle that if you want air conditioning.
