Furnace vs Boiler in Fulton County, Georgia

When a furnace makes sense

If your house already has ductwork, a furnace is the straightforward choice. Winters here only dip to about 35°F on an average night, and you're only running heat around six months of the year, so you don't need a system built for extreme cold. A furnace paired with that ductwork also lets the same blower handle central air conditioning, which a boiler can't do.

When a boiler makes sense

A boiler makes sense if your home already has radiators or in-floor pipes rather than ducts, since that's how it delivers heat. It runs about 5% cheaper than a furnace here at current Georgia gas prices, which is worth something even with six mild winter months to cover. Just know it heats only, so you'd still need a separate way to cool the house.
