Furnace vs Boiler in Middlesex County, Massachusetts
When a furnace makes sense
If your house already has ductwork, a furnace is the straightforward choice. It'll also carry central air conditioning through those same ducts if you ever want to add it, which a boiler can't do. Winters here get down to 19°F on average at night, and a gas furnace is built to keep up with that.
When a boiler makes sense
If your home heats through radiators or in-floor pipes rather than ducts, a boiler is the natural fit, since it's built to run on that kind of system. It also runs about 5% cheaper than a furnace at Massachusetts gas prices, which adds up over an 8-month heating season. The tradeoff is that a boiler only heats, so it won't give you a path to central air conditioning the way a furnace's ductwork can.
