Furnace vs Boiler in Washtenaw County, Michigan

When a furnace makes sense

If your house already has ductwork, a furnace is the straightforward choice. It ties into what's there, and with 8 months of heating a year and winter nights averaging 19°F, that ductwork will get steady use once the weather turns.

When a boiler makes sense

If your home heats through radiators or in-floor pipes rather than ducts, a boiler is the right match, since a furnace has no way to connect to that kind of system. It also runs about 5% cheaper here at Michigan gas prices, which adds up over 8 months of heating.
