Furnace vs Boiler in Campbell County, Kentucky
When a furnace makes sense
A furnace is the right call if your house already has ductwork, since it can also carry central air conditioning through the same ducts. It responds fast on a 26°F night, pushing warm air as soon as it fires. If your home already has a furnace and the ducts are in good shape, replacing like with like is usually the simplest path.
When a boiler makes sense
A boiler suits a house that already has radiators or baseboard heat and no ductwork to speak of. It runs about 5% cheaper than a furnace here, and the heat it puts out tends to feel steadier through a long, cold night. If you already have one and the piping is sound, staying with a boiler makes sense even though a furnace would edge it out for most homes in the county.

Furnace wins in Campbell County.
Most homes here were built in 1972, and homes that age already have the ductwork a furnace needs, which makes it the easier install.
If your home already has radiators or in-floor piping instead of ductwork, a boiler still makes more sense than adding ducts for a furnace.
