Heat runs all year here, and the power doesn't always stay on
Sitka does not really have a cooling season. Summer afternoons average 60°F, so the furnace or heat pump barely gets a break before winter sets back in. That means your heating system is working every month of the year, with none of the downtime other places give it to rest and get checked over.
Winter nights averaging 31°F keep the burner or compressor cycling on and off for months straight, and every cycle puts wear on the igniter and the motor that pushes air through the ducts. Add in the wind. The borough has logged five damaging wind events and two winter storms over the past decade, and statewide, one in five households lost power for at least a day in 2024. When the power drops, your system stops with it, and if it does not come back on by itself, you will notice the house going cold fast.

Alaska requires contractors to register with the state.
Alaska's rule puts the business on file. There's no trade exam behind that record, and no state board testing the person who shows up to work on your system. The registration tells you the contractor is on record with the state, not that anyone checked their skill at diagnosing or repairing a heating and cooling system.
For this job, that record is what the state offers, and nothing more. No state license stands behind the repair, so whatever protection exists here comes from somewhere other than a state trade exam.

- Why is my heat not working?
- Start with the thermostat. Check that it's set to heat, not fan, and that the temperature is set above room temperature. If that looks right, check your breaker panel, since a furnace that lost power will not restart on its own. Gas furnaces use an igniter to light the burners, and when it fails the furnace will run air but never produce heat. With winter nights here averaging 31°F, a furnace that won't fire is not something to leave for later.
- Why is my system running but not cooling the house?
- If air is moving but it isn't cold, check the filter first. A clogged filter restricts airflow enough to keep a system from cooling. A frozen evaporator coil will also blow warm air, and it usually freezes because of low airflow or a refrigerant problem. If the outdoor unit isn't running at all while the indoor blower is, that points to the outdoor fan motor or the capacitor that starts it, and a contractor will need to check it.
- What can I check before calling for HVAC repair?
- Check the thermostat settings first, since a wrong mode or setpoint looks exactly like a broken system. Check the breaker panel for a tripped breaker, especially after a storm, since wind events do happen here and can cut power to the unit. Check the filter and pull it out if it's visibly clogged, since restricted airflow causes problems in both furnaces and air conditioners. If the system still isn't working after that, a licensed contractor will need to diagnose it, and Alaska requires contractors to register with the state, so it's worth confirming that before they come out.
