Ten months of heat, mild summers
Your furnace in Oak Harbor works from September through June. That is ten months of the year with barely a break, and on winter nights that average 35°F it cycles on and off most of the night to hold the house steady. Each cycle means another start, and the igniter and the flame sensor are what wear down first from all that on and off.
Summer afternoons here only average 71°F, so an air conditioner or heat pump barely runs in cooling mode. More homes here heat with electricity than with gas, and when the power goes out, the furnace stops with it. Most systems restart on their own once power is back. In Washington, close to a quarter of households went at least 24 hours without power in 2024, so if yours does not come back on by itself, that is worth a call.

Washington requires contractors to register with the state.
The registration puts the business on file with Labor and Industries. It does not mean anyone tested this contractor's knowledge of heating and cooling systems. There is no trade exam behind that registration number, so it tells you the business exists on paper, not that the state checked their skill.
For a heating and cooling repair, that registration is what stands behind the business, not a measure of how well they know this trade. Nothing in the state's rule speaks to the work itself, only to whether the business is on record.

- 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 and any switch that looks like a light switch near the furnace, since that's how most units are shut off for service. If those are fine, listen for the furnace trying to start. A few clicks followed by silence usually points to the igniter or the flame sensor, both parts a contractor can test in minutes. With winters here running cold from December through February, don't wait long on a furnace that won't hold a flame.
- 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 when that happens the coil can ice over so the system runs but pushes out warm air. Check the outdoor unit too. If the fan isn't spinning or the area around it is packed with leaves or debris, the unit can't move heat out of the house no matter how long it runs. If the filter is clean and the outdoor fan is turning, the refrigerant charge or a failing part inside the unit is more likely, and that calls for a contractor with gauges to check it properly.
- What can I check before calling for HVAC repair?
- Check the thermostat batteries and settings first, since a thermostat set to the wrong mode or with dead batteries looks exactly like a broken system. Check the breaker panel next. Then look at the air filter and swap it if it's dark with dust, since a blocked filter causes problems that look like bigger failures. If the system runs on electric heat, which covers 57.9% of homes here, a tripped breaker after a power blip is worth checking before anything else. Once you've ruled those out, tell the contractor what you found. It helps them get to the actual problem faster.
