Furnace vs Boiler in Boone County, Kentucky
When a furnace makes sense
If your home already has ductwork, a furnace makes sense, and that covers most houses in the county. It also answers cooling later, since the same ducts can carry air from a central air conditioner when you need it. Seven months of heating a year is real work for any system, and a furnace built more recently will handle those 26°F nights without trouble.
When a boiler makes sense
A boiler is worth a look if your home already has radiators or in-floor piping instead of ducts. It runs about 5% cheaper to operate here at current Kentucky gas prices, and it heats evenly through those cold nights without blowing air. If you would need to add ductwork just to run a furnace, the boiler is the simpler path.
