Furnace vs Boiler in Anchorage Municipality, Alaska
When a furnace makes sense
If your house already has ducts, a furnace is the straightforward choice, and just over half the homes in this region have them. It heats fast, which matters when winter nights average 10°F and the heat runs nearly year round. It runs on natural gas, same as a boiler, without needing radiators or in-floor pipes.
When a boiler makes sense
If your home already has radiators or in-floor pipes instead of ductwork, a boiler makes sense without any of the work a furnace would need. Boiler heat runs about 5% cheaper here, which adds up over 12 months of heating a year. Only a small share of homes in this region use one, so it usually comes down to what's already installed in your house.

Furnace wins in Anchorage Municipality.
In the Pacific states, 56.9% of homes heat with a furnace, so just over half already have the ductwork it needs.
If your home already heats through radiators or in-floor pipes rather than ductwork, a boiler is still worth the money over switching to forced air.
