Heat runs all year here, and the cold is real

Your furnace runs every month of the year in Juneau. There's no season where it gets a break, and on winter nights averaging 26°F it's cycling on and off for hours at a stretch. Almost half the homes here heat with fuel oil, and that system depends on a steady fuel supply and a clean burner to keep firing through months of hard use.

Juneau sees real winter storms, 18 of them over the last ten years, along with 13 damaging wind events. Weather like that knocks out power, and when it does your furnace stops no matter how well it was running before. If yours doesn't come back on once power is restored, or if it's been struggling to keep up with the cold, that's worth having looked at.

Alaska requires contractors to register with the state.

That registration puts the business on file with the state, along with its contact information. Nobody tested the contractor's knowledge of heating and cooling work to grant it, and it is not a record of what jobs they have done or how well they did them.

So for a repair like this, the registration is not what stands behind the work. It confirms the business is on file, nothing more. The state's rule does not reach into whether the person doing this repair knows how to do it safely or well.

Why is my heat not working?
Start with the thermostat. Make sure it is set to heat and the setpoint is above room temperature, since a battery running low can reset it without warning. If that checks out, look at the system itself. A furnace that will not start at all often has a tripped breaker or a safety switch that shut it off, and if you heat with fuel oil, check that the tank is not empty since that is a common reason for no heat at all. If the system runs but the air feels cool or the house never warms up, that points to a different problem and is worth a contractor's look, especially with winter lows here around 26°F.
Why is my system running but not cooling the house?
If the blower is running but the air is not cold, the most common cause is a dirty filter or blocked return choking off airflow. A frozen coil can also cause this, and it happens when airflow is restricted long enough that moisture on the coil freezes instead of draining. Given that summer afternoons here average 63°F, most homes get by without central air, so if this is happening on a heat pump in cooling mode, a contractor should check the refrigerant charge and the coil directly.
What can I check before calling for HVAC repair?
Check the thermostat first. Confirm it is set correctly, the batteries are good, and the display is responding. Next, check the breaker for the system, since a tripped breaker will stop it cold with no other symptoms. Look at the air filter and replace it if it is visibly dirty, since restricted airflow causes problems that look like bigger failures than they are. If you heat with fuel oil, confirm there is fuel in the tank. If the unit is outside, clear away snow or ice blocking the intake or exhaust vents, especially after one of the winter storms this area sees most years. If none of that resolves it, a licensed contractor can diagnose what is actually wrong.
