Furnace vs Boiler in Berkeley County, South Carolina
When a furnace makes sense
If your house already has ductwork, a furnace is the easier call. Winters here are short and mild, nights average 38°F from December through February, and most homes only need heat for about 5 months. A furnace brings a room up to temperature quickly through those ducts, which suits a season that doesn't ask much of a heating system.
When a boiler makes sense
A boiler is worth a look if your home already has radiators or in-floor pipes instead of ducts, or if you want the steadier, quieter heat that comes through them. It runs about 5% cheaper here at South Carolina gas prices, and with only about 5 months of heating needed a year, that difference matters less than it would somewhere colder. It's a smaller path here, just 2% of homes in the region heat this way, so it tends to fit specific setups rather than most houses.
