Furnace vs Boiler in Davidson County, Tennessee
When a furnace makes sense
A furnace makes sense if your home already has ductwork in place, since it heats through the same runs that carry your air conditioning. With winter nights averaging 31°F and heat needed about seven months of the year, a furnace paired with central air covers both jobs through the same ducts.
When a boiler makes sense
A boiler makes sense if your home already has radiators or in-floor piping rather than ducts, since that's how it delivers heat. It runs about 5% cheaper than a furnace here on gas, which adds up over seven months of heating a year. Keep in mind a boiler only heats, so cooling the house in summer would need a separate system.

Furnace wins in Davidson County.
Most homes in Davidson County were built in 1986, 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 is still the better choice.
