A furnace that has to work all year, in real cold
Galena needs heat every month of the year. Winter nights average -14°F from December through February, and a furnace here runs through weather most of the country never sees. That kind of cold means long burn cycles and a unit sized and installed to keep up with it, not just handle a cold snap.
Over half of homes in the area heat with fuel oil, so an oil furnace is a normal choice here, not an exception. Power is worth planning around too. Across Alaska, one in five households lost power for 24 hours or more in 2024, and the area has logged 15 winter storms and 5 damaging wind events over the past ten years. A new furnace also has to meet the federal minimum of 80.0 percent AFUE if it runs on gas and isn't weatherized.

Alaska requires contractors to register with the state.
Alaska's registration puts the business on file with the state. Nobody tested the contractor's furnace work to get that number, and the state does not track how the job was done, only that the business exists and is registered.
With no license behind this job, the check that matters is the local one. In most cities and counties, a furnace installation needs a permit from the local building office, along with an inspection once the work is done. That inspection is what stands in for a license here, the record that someone looked at the finished work.

- What size furnace does my house need?
- The right size depends on your home's square footage, insulation, window count, and ceiling height, so there's no single number that fits every house. A contractor works this out with a load calculation, not a guess based on the size of your old furnace. This matters here since winter nights average -14°F and your furnace has to keep up with that for months at a stretch. A furnace that's too small will run constantly and still fall behind. One that's too big will cycle on and off and wear out faster.
- How do I know it's time to replace my furnace?
- Watch for frequent repairs, uneven heat from room to room, and a furnace that struggles to keep up on the coldest nights. Age matters too, and a unit working overtime through winters like the ones here is more likely to fail when you need it most. Homes in this area need heat all 12 months of the year, so a furnace nearing the end of its life is a bigger risk than it would be somewhere with a short heating season. If yours is older and you're already calling for repairs more than once a season, replacement is worth discussing with a contractor before it fails outright.
- Is a high-efficiency furnace worth it?
- It depends on how much heating your home needs and how long you plan to stay in it, so a contractor can walk through the numbers for your specific situation. What's true everywhere is that every non-weatherized gas furnace made since November 2015 has to reach at least 80 percent AFUE, so even a standard furnace today isn't the inefficient equipment of decades past. High-efficiency models go beyond that minimum, and in a place where furnaces run all year rather than a few months, fuel savings have more months to add up. More than half of homes here heat with fuel oil rather than gas, so ask a contractor how efficiency ratings apply to the fuel type your home actually uses.
