Furnace vs Boiler in Fairbanks North Star Borough, Alaska
When a furnace makes sense
If your house already has ductwork in place, a furnace is the simpler match, since it heats through that ductwork rather than radiators or pipes. With nights averaging -10°F from December through February and heat needed most of the year here, forced air recovers quickly once it kicks on. It runs on natural gas, same as the boiler, so the running cost gap between the two is small.
When a boiler makes sense
If your home has radiators or in-floor pipes rather than ducts, a boiler fits what is already there instead of asking you to add ductwork. It runs about 5% cheaper than a furnace here, and with heat needed roughly 11 months a year, that difference adds up. Through the long stretch of nights near -10°F from December through February, that steady lower cost is worth weighing.
