Furnace vs Boiler in Wilson County, Tennessee
When a furnace makes sense
If your ductwork is already in place, or your home doesn't have radiators or baseboard heating units, a furnace is the simpler path. It heats fast, which matters on the 31°F nights you'll see from December through February, and gas furnaces are a known quantity for the 36% of homes here already on gas. A furnace only heats, so pair it with your existing central air for cooling.
When a boiler makes sense
A boiler suits a home already set up with radiators or in-floor heating loops rather than ducts. It runs about 5% cheaper to heat with here, which adds up over the 7 months a year this county needs heat. Like a furnace, it only heats, so you'll still need a separate system for summer.

Furnace wins in Wilson County.
Most homes in Wilson County were built in 2000, and homes that age are set up for ductwork, which makes the furnace the easier install.
If your home already has radiators or in-floor piping instead of ductwork, a boiler still makes more sense than adding a furnace.
