Furnace vs Boiler in Matanuska-Susitna Borough, Alaska
When a furnace makes sense
If your house already has ductwork, a furnace is the straightforward choice. Those same ducts can carry cooled air in summer if you ever add central air, which a boiler can't do. With winter nights averaging 12°F and heat needed most of the year, you want a system that's easy to service without opening up floors or walls.
When a boiler makes sense
If your home heats through radiators or in-floor pipes already, stay with a boiler rather than tearing that out for ductwork. Boiler heat runs about 5% cheaper here than a furnace, which adds up when you're heating close to 12 months a year. The tradeoff is that a boiler only heats. It won't give you central air down the road.
