In Wasilla, your furnace runs all year
Winter nights here average 12°F from December through February, and that is when a furnace works hardest. But in Wasilla the need for heat does not really stop. Homes here run their furnace 12 months a year, so a new one has to hold up to steady use, not just a hard winter.
Most homes here heat with gas. Any non-weatherized gas furnace built since November 2015 has to reach at least 80 percent AFUE, so that is the floor to expect when you replace one. Alaska also sees real power outages, with 21% of households going at least a day without power in 2024, worth asking about if you want a furnace that can restart cleanly once the power is back.

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 there is no license number tied to a trade exam. It tells you the business is registered to operate in Alaska, nothing more.
For a furnace install, the protection here comes from the permit process instead. In most cities and counties, a furnace replacement needs a permit from the local building office, with an inspection once the work is done. That inspection is what catches a bad gas connection or a venting mistake, the kind of error that matters most on a gas furnace. In Matanuska-Susitna Borough, 71.2% of homes heat with gas, so that inspection step is doing real work.

- What size furnace does my house need?
- There's no single number that fits every house. It depends on your home's square footage, insulation, window count, and layout. A contractor works this out with a load calculation, which looks at how much heat your home actually loses on a cold night. With winter lows here averaging 12°F, getting this right matters. Too big and the furnace short cycles instead of heating evenly. Too small and it runs constantly but can't keep up when it's coldest.
- How do I know it's time to replace my furnace?
- Watch how often you're calling for repairs. If it's more than once a season, replacement is worth considering instead of another fix. Other signs include uneven heat between rooms, a furnace that runs longer to reach the same temperature, or a technician telling you the heat exchanger is cracked. Homes here need heat all 12 months of the year, so a furnace that's struggling never gets a break to recover, which tends to speed up wear.
- Is a high-efficiency furnace worth it?
- It depends on how much you heat and how long you plan to stay in the house. A high-efficiency furnace sends less fuel up the flue and more into your home. Since homes here run the furnace all 12 months of the year, that efficiency gets used constantly instead of sitting idle part of the time. Any new non-weatherized gas furnace installed now has to reach at least 80.0 percent AFUE by law, so the real choice is how much higher above that minimum to go. A contractor can walk through the options and what fits your house and your gas use.
