Furnace vs Boiler in Norfolk County, Massachusetts
When a furnace makes sense
If your house already has ductwork, a furnace is the simpler path. It heats and cools through the same ducts if you ever add central air, which a boiler can't do. With eight months of heating a year and nights averaging 21°F, you want equipment matched to what's already running through your walls.
When a boiler makes sense
If your home heats through radiators or in-floor pipes, a boiler is the natural fit rather than a furnace you'd need new ductwork for. Boiler heat runs about 5% cheaper here than furnace heat, and that gap matters over eight months of heating a year. It won't provide cooling, so you'd still need a separate answer for summer.
