Furnace vs Boiler in Pulaski County, Kentucky

When a furnace makes sense

If your ductwork is already in place and working well, a furnace is the simpler match for it. It also brings heat up faster on a 28°F morning, since it pushes hot air the moment it fires rather than waiting on water to heat. For most homes here, this is the safer default choice.

When a boiler makes sense

If your home already has radiators or in-floor piping instead of ducts, a boiler is the one that fits what you have. It runs about 5% cheaper to operate here at Kentucky gas prices, which adds up over seven months of heating a year. Choose it when your distribution system is already built around water, not air.
