Furnace vs Boiler in Cumberland County, Maine
When a furnace makes sense
If your house already has ductwork, a furnace is the easier fit and gives you central air down the road on the same ducts. Nine months of heating season here means the furnace is working hard most of the year, and gas keeps that running cost reasonable even at 15°F. This is the choice that matches what most homes in this region already have in place.
When a boiler makes sense
If your home heats through radiators or in-floor pipes rather than ducts, a boiler works with what you already have instead of asking you to add ductwork. It runs about 5% cheaper than a furnace here on gas, and that gap matters over nine months of heating season and nights averaging 15°F. It suits a house built around that kind of heat, not one already set up for ducts.
