Furnace vs Boiler in Guilford County, North Carolina
When a furnace makes sense
If your home already has ductwork, a furnace is the straightforward choice. Winters here are not extreme, averaging 31°F on winter nights, and you only need heat about seven months of the year, so the system is not working hard for long stretches. Ductwork also means the same system can carry cooling in summer, which a boiler cannot do.
When a boiler makes sense
A boiler makes sense if your home is set up for radiators or in-floor pipes rather than ducts. It runs about 5% cheaper than a furnace at North Carolina prices, which adds up over seven months of heating a year. It fits best when the house is already built to carry heat that way, since running new ductwork is not part of the job.
