Furnace vs Boiler in Franklin County, Massachusetts

When a furnace makes sense

If your house already has ductwork, a furnace is the straightforward choice. It heats the air directly and gets your rooms warm fast, which matters when nights are dropping to 17°F for months at a time. The same ducts can carry cooled air in summer if you add central air later.

When a boiler makes sense

If your home is set up with radiators or in-floor pipes instead of ducts, a boiler is the right fit rather than something to add ductwork for. Boiler heat runs about 5% cheaper here than a furnace, and it holds a steadier warmth through the long stretch of cold from December through February. With eight months of heating season here, that steadier heat is worth something.
