Your furnace never gets a break here
In Anchorage, your furnace runs all year. There's no stretch where it gets to sit idle, and on winter nights averaging 10°F, it cycles on and off for hours at a time to keep up. Every one of those starts puts load on the igniter and the parts that control the flame. Most homes here heat with gas, so that wear is happening in the house next to yours too. When the igniter finally gives out, the furnace won't light at all, and you'll notice fast because there's no summer stretch mild enough to hide it.
Summer afternoons average 66°F here, mild enough that cooling almost never runs. So when something is wrong with your system, it's almost always the heat, and it's almost always in the cold months when you need it most. Add in that 21% of Alaska households went at least 24 hours without power in 2024, and a furnace that won't restart on its own once power is back is a real problem, not a rare one.

A new furnace and air conditioner would cut about $210 a year off heating and cooling for a typical Anchorage Municipality home.
Estimates for a typical Anchorage Municipality home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Alaska fuel prices and NOAA climate normals. Your home will differ.
Repair makes sense when one part has failed.
Replacement makes sense when the furnace's heat exchanger is cracked, the air conditioner's compressor has failed, or repairs keep coming.
Alaska requires contractors to register with the state.
Registration puts the business on file with the state. Alaska does not test the contractor or license the trade, so a registration number tells you the business is on record, not that anyone checked its work.
For a repair on a heating and cooling system, that record is what exists here. There is no trade exam behind it and no state license standing over the job. Whatever confidence you have in the work has to come from the contractor directly, since Alaska's registration was never built to vouch for it.

- Why is my heat not working?
- Start with the thermostat. Make sure it's set to heat and the temperature is set above room temperature, since a low battery or a setting bumped by accident causes more no-heat calls than people expect. If the thermostat looks right, check your breaker panel for a tripped breaker and make sure the furnace switch, the one that looks like a light switch near the unit, is on. Gas furnaces also need the gas valve open. If none of that explains it, the igniter or the flame sensor may have failed, and that's a repair for a licensed contractor. With winter nights here averaging 10°F, a furnace that's down for even a few hours is worth treating as urgent.
- Why is my system running but not cooling the house?
- Check the air filter first. A filter clogged with dust blocks airflow across the coil, and the coil can ice over when air can't move past it fast enough, which stops it from pulling heat out of the house even though the unit keeps running. Check that the outdoor unit isn't blocked by anything and that the vents inside the house are open. If your system is a heat pump, make sure it's actually set to cool rather than heat. Beyond that, low refrigerant or a failing part is a job for a contractor to diagnose.
- What can I check before calling for HVAC repair?
- Check the thermostat settings and its batteries first. Then check the breaker panel for anything tripped, and look at any power switch on or near the furnace itself to make sure it's on. Check the air filter and replace it if it's visibly dirty, since restricted airflow causes problems that look like bigger failures. If the unit uses gas, confirm the gas valve is open. About a fifth of Alaska households lost power for at least 24 hours at some point in 2024, so if the outage was recent, give the system a few minutes after power returns before deciding it's broken. If you've checked all this and the system still isn't working, a licensed contractor can diagnose what's left.
