Kupreanof asks a furnace to run all year with no break
There is no season off here. Summer afternoons average 61°F, cool enough that the furnace still answers on plenty of days. Winter nights average 28°F from December through February, and the furnace runs every night for months straight. That kind of nonstop cycling wears on the igniter and the blower motor faster than a system that gets half the year to rest.
More than half the homes here heat with electricity, so a power outage takes the heat down with the lights. Alaska households saw outages of 24 hours or more in 21% of cases last year, and this area has logged 5 winter storms and 2 damaging wind events over the past ten years. Most electric furnaces start back up on their own once power returns. If yours does not, or it sounds rough after running steady for months, that is worth having looked at before the next storm.

Alaska requires contractors to register with the state.
Registration puts the business on file with the state. Alaska does not test contractors on the trade before they register, so it is not a credential and it does not say anything about whether the person doing the work knows heating and cooling systems.
On a job like this, that record is what exists. It is not a license and it does not stand in for one. Nothing in Alaska's registration tests a contractor's gas or refrigerant work before they touch your system, and nothing in it inspects the work after.

- Why is my heat not working?
- Start with the thermostat and the power to the furnace. If the thermostat screen is blank, check the breaker before assuming the furnace itself has failed. On a gas furnace, a pilot that will not stay lit or an igniter that clicks but never catches means the burner is not getting a steady flame. Electric heat that blows cold air more often points to a tripped limit switch or a failed heating element. With heat needed here through every month of the year, a furnace that will not run is worth calling in fast rather than waiting to see if it comes back on its own.
- Why is my system running but not cooling the house?
- In this climate that usually is not a cooling problem at all. Summer afternoons here average 61°F, mild enough that most homes get by without air conditioning. If a furnace fan is running but the air feels wrong, check whether it is actually blowing warm, since that points back to the heating side, or whether a duct has come loose and is dumping air somewhere other than the room you're in.
- What can I check before calling for HVAC repair?
- Check the thermostat first. Make sure it is set to heat, the temperature is above room temperature, and it has power. Next check the breaker for the furnace and, if it uses one, the fuel supply. Look at the filter too, since a clogged one restricts airflow enough to cause shutdowns. Winter nights here average 28°F, and with storms known to knock out power in this area, if the furnace lost power during an outage it may need to be reset once power is back before it will fire again.
