Your furnace runs every month of the year here
In Delta Junction there is no season when the furnace gets a break. It runs all 12 months, and on winter nights that average -10°F it cycles on and off for hours at a stretch. Every start puts a load on the igniter and the burner assembly, and at that temperature a misfire means the house goes cold fast.
56.3% of homes here heat with fuel oil, and that kind of heat puts wear on the burner, the nozzle, and the fuel line. Power is part of the problem too. In 2024, 21% of Alaska households went at least 24 hours without power, and a furnace with no power will not restart on its own. If the house is losing heat and the thermostat is dark, that is why.

Alaska requires contractors to register with the state.
That registration puts the business on file with the state and gives it a number. Nobody at the state tested this contractor on furnace repair to issue it. There is no trade exam behind it and no license to revoke if the work goes bad. It tells you the business is on record. It does not tell you the work will be done right.
For a furnace, the gas connection is the part that matters most. A bad one is what makes the job dangerous. Alaska's registration is a business record and does not test or inspect that connection. No license stands behind this repair in Southeast Fairbanks. The registration is what exists, and it is only a record that the business is on file.

- Why won't my furnace turn on?
- Most often it's the thermostat, the power supply, or a safety switch that's stopped the furnace from starting. Check that the thermostat is set to heat and the temperature is above room temperature, and check the furnace switch and breaker. If those look fine, the igniter or a flame sensor reading dirty may be holding the system off, and that's a job for a contractor to check. With winter nights here averaging -10°F, it's worth having a backup heat source ready while you wait, since 21% of Alaska households went at least a day without power last year.
- Why is my furnace blowing cold air?
- If cold air is coming from the vents, the furnace may be running the blower without the burners lit. That points to an ignition problem, a gas supply issue, or a limit switch that's shut down the burners as a safety measure. A furnace blowing cold air is not heating your home even though it sounds like it's running, so don't wait on this one with fuel oil heat especially, since a stalled burner can mean the oil isn't igniting at all. A contractor will need to check the ignition system and the burner assembly to find out why the flame isn't staying on.
- Why won't my furnace pilot light stay lit?
- A pilot light that won't stay lit is usually a sign the thermocouple has worn out and is no longer sensing the flame correctly. It can also mean a draft is blowing the flame out or the gas valve isn't feeding it enough fuel. A standing pilot doesn't draw power, so a power outage isn't the cause, but the parts around it can wear out over time and need replacing. A contractor can test the thermocouple and gas valve and replace whichever one is failing.
