Furnace vs Boiler in Onondaga County, New York
When a furnace makes sense
If your home already has ductwork, a furnace is the straightforward choice. Onondaga County sees winter nights down around 18°F, and a furnace pushes heated air through the vents fast enough to keep up. The same ducts can carry air conditioning in summer, which a boiler can't do.
When a boiler makes sense
If your home heats with radiators or in-floor pipes rather than ducts, a boiler is the right fit, and it costs about 5% less to run here than a furnace. Hot water holds its heat well through the long stretch of cold this area gets, with heat needed roughly eight months of the year. It won't move air for cooling, so you'd still need another way to handle summer.
