Furnace vs Boiler in Kenton County, Kentucky
When a furnace makes sense
If your home already has ductwork, a furnace is the simpler path, since that same ductwork can carry cooling later if you ever add central air. It also responds fast on the cold nights this county sees, pushing warm air the moment it kicks on rather than waiting on water to heat up. With seven months of heating ahead each year, that quick response matters more than the small edge boilers have on running cost.
When a boiler makes sense
A boiler fits a home that already has radiators or in-floor piping instead of ducts, since ripping those out to add ductwork is the real cost to avoid. It runs about 5% cheaper than a furnace here, and the heat it puts out tends to hold longer once the house is warm, which counts for something at 26°F. If your home was built with hot water heat in mind, staying with a boiler is usually the straighter choice.
