Furnace vs Boiler in Madison County, Kentucky
When a furnace makes sense
If your ductwork is already in place, a furnace is the straightforward choice. It heats the air directly and can push a house back up to temperature quickly on a 27°F night, which matters over a seven month heating season. It's the simpler system to service when something goes wrong, since most of the parts are easy to reach through a single cabinet.
When a boiler makes sense
A boiler suits a house that already has radiators or in-floor piping rather than ducts. Heating with one runs about 5% cheaper here than a furnace, and the heat it puts out tends to feel steadier through a long, cold winter. It's worth choosing on its own terms, for how it heats a house that's set up for it, not as a stand-in for ducted air.
