Your furnace runs all year here
In Glennallen there's no season when the heat shuts off. Homes here need it 12 months a year, and winter nights average -9°F from December through February. A furnace sized for that has to hold the house steady through months of hard cold, not just a few weeks of it.
Most homes here run on fuel oil, and a new furnace needs to be matched to that. In Alaska, 21% of households went at least 24 hours without power in 2024, so it's worth asking how a furnace will behave when the power drops. A non-weatherized gas furnace built new has to reach at least 80 percent AFUE, and that's the floor to expect no matter who installs it.

Alaska requires contractors to register with the state.
That registration puts the business on file with the state. Nobody tested the contractor's work and no license backs it up. It just means the state knows the business exists.
For a furnace install, the protection that matters comes from the local building office, not the state. Replacing a furnace needs a permit in most cities and counties, and an inspector checks the work when it's done.

- What size furnace does my house need?
- The right size comes from a load calculation, not a guess based on square footage. A contractor looks at your insulation, your windows, your ceiling height, and how the house is laid out before landing on a number. This matters more here than in most places, since a furnace that runs all year at -9 degree lows has no slow season to hide an undersized or oversized unit.
- How do I know it's time to replace my furnace?
- If it's struggling to keep the house warm, cycling on and off more than it used to, or needing repairs more often, those are the signs. A furnace that's losing ground in weather this cold puts the whole house at risk, since heat isn't optional here for even a month out of the year. A contractor can tell you whether what you're seeing is a fixable problem or the furnace reaching the end of its life.
- Is a high-efficiency furnace worth it?
- For a house that runs its furnace year round, efficiency matters more than it would somewhere with a short heating season. Any non-weatherized gas furnace built since November 2015 has to hit at least 80 percent AFUE, so the real question is whether it makes sense to go higher than that minimum for your house. That depends on your current furnace, your fuel type, and how the house holds heat, which a contractor can walk through with you.
