Furnace vs Boiler in Calhoun County, Alabama
When a furnace makes sense
A furnace suits most homes here, especially if you already have the ductwork in place for it. Winters are mild, with nighttime lows around 34°F and only about five months of heating needed, so you're not asking the system to work hard for long stretches. Furnaces also heat up a room faster than a boiler can, since they push warm air through the vents right away instead of waiting for water to heat.
When a boiler makes sense
A boiler makes sense if your home already has radiators or in-floor piping instead of ducts, since that's the delivery system it needs to work. It runs about 5% cheaper than a furnace on gas here, which matters more in a house with high ceilings or rooms that hold heat unevenly. If you're not replacing an existing boiler system, the case for switching to one is thinner given how short the heating season runs here.

Furnace wins in Calhoun County.
Most homes here date back to 1979, and homes that age almost always already have ductwork in place, which is what makes a furnace the easier fit.
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.
