Furnace vs Boiler in Plymouth County, Massachusetts

When a furnace makes sense

If your house already has ducts, a furnace is the straightforward choice. It heats the air directly and pushes it through the house fast, which matters when nights are sitting at 23°F for months at a stretch. You get eight months of use out of it most years, so it earns its keep.

When a boiler makes sense

If your home is set up with radiators or in-floor pipes instead of ductwork, a boiler is the right fit rather than a reason to add ducts. Heating with a boiler runs about 5% cheaper here than a furnace, and that gap adds up over a winter this long. It won't move air for cooling later, but for heat alone through radiators it does the job well.
