Furnace vs Boiler in Southeast Fairbanks Census Area, Alaska
When a furnace makes sense
If your house already has ductwork, a furnace is the simpler call. It heats the same air your ducts already move, and with nights averaging -10°F from December through February, you want equipment your home is already built around. Just over half the homes in this region have that ductwork in place, and with heat needed close to 12 months a year, that fit matters.
When a boiler makes sense
If your home already has radiators or in-floor pipes instead of ducts, a boiler is worth keeping. It runs about 5% cheaper to heat with here, and with heat needed close to 12 months a year, that gap adds up. It only makes sense where that piping already exists, since there are no ducts to run it through instead.
