Your furnace runs every month of the year here
In Sitka, heat is not a seasonal job. Homes here need it all 12 months, and winter nights from December through February average 31°F. The burner and blower do not get the summer rest they get elsewhere, and that steady work wears on the parts that start the furnace and move the air.
Power is part of the picture too. Across Alaska, 21% of households went at least 24 hours without power in 2024, and Sitka has logged 2 winter storms and 5 damaging wind events over the past ten years. A furnace that loses power and comes back on is more likely to show a problem that was already there, often as a furnace that will not restart or one that runs but never gets the house warm.

Alaska requires contractors to register with the state.
Registration puts the business on file with the state. It confirms the company exists and can be traced if something goes wrong, but nobody tested the person coming to your house on furnace repair before that record was created.
Because Alaska stops at registration, there is no state exam or license standing behind the work on your furnace. Gas connections are the dangerous part of this job, and the registration itself does not check that work. It only confirms the business is on file.

- Why won't my furnace turn on?
- Usually it's the thermostat, the power supply, or the ignition system. Check that the thermostat is set to heat and the temperature is actually above room temperature. If the furnace still won't respond, check the breaker and the switch that looks like a light switch near the unit, sometimes it gets bumped off. When those check out fine, the problem is likely inside the unit itself, in the ignition system or a safety switch that's stopping it from starting, and that needs a contractor to diagnose.
- Why is my furnace blowing cold air?
- Most often the furnace is running the fan without the burners lighting. That can mean the igniter isn't working, the flame sensor isn't detecting a flame, or the gas valve isn't opening. It can also mean the thermostat fan setting is stuck on instead of auto, which just circulates air without heating it. With winter lows around 31°F here, this isn't something to wait out. A contractor can check the ignition system and get it firing again.
- Why won't my furnace pilot light stay lit?
- The thermocouple is the most common cause. It's the small sensor that sits in the pilot flame and tells the gas valve the pilot is lit. When it wears out or shifts out of position, the gas valve reads it as no flame and shuts off the gas, even though the pilot was burning fine. A draft blowing across the pilot can also blow it out repeatedly. If relighting it keeps failing the same way, the thermocouple usually needs replacing, which is a job for a contractor rather than something to keep retrying.
