Furnace vs Boiler in Nassau County, New York
When a furnace makes sense
If your house already has ductwork, a furnace is the straightforward choice. That same ductwork can carry central air conditioning, so you get cooling for those months without running separate lines through the house. With winter nights averaging 28°F here, you want a system that can move heat quickly, and a furnace does that as soon as the ducts are in place.
When a boiler makes sense
If your home heats through radiators or pipes in the floor rather than ducts, a boiler is the natural fit, since it was built to run that way. It also costs about 5% less to run here than a furnace, which adds up over the roughly 8 months a year you'll have it on. The tradeoff is that a boiler only heats, so cooling your home means a separate system.
