Ten months of heat, one bad storm away
Your furnace in Lacey runs from September through June. That is ten months of the year with the burner lighting and the blower pushing air through the house, night after night when it drops to 34°F outside. All that run time adds up on the igniter and the blower motor long before summer gives the system a rest, and summer here barely asks anything of it at 75°F.
Most homes in this area heat with electricity, so when the power goes out, the heat goes with it. Outages are not rare here. Nearly a quarter of Washington households lost power for a full day or more in 2024. When your furnace won't restart after the lights come back on, that is often the sign something already worn gave out under the strain, not the outage itself.

Washington requires contractors to register with the state.
That registration means the business is on file with the Department of Labor and Industries. It is not a trade license. Nobody tested this contractor on how to repair a furnace or an air conditioner before handing them that number.
So for a heating and cooling repair, the registration tells you the business is on record with the state. It does not tell you the state checked their work. Gas repair matters because a bad connection is the dangerous part of the job, and registration does not test anyone on gas work.

- Why is my heat not working?
- Start with the thermostat. Make sure it is set to heat and set a few degrees above room temperature, and check that the display is lit. If the thermostat looks dead, check the breaker for the furnace and the switch that looks like a light switch near the unit, since that shuts it off too. Gas furnaces have an igniter that wears out over time, and when it fails the furnace will run its fan but never produce heat. If power and settings check out and you still get no heat, that points to something a contractor needs to look at, like the igniter, the flame sensor, or the gas valve.
- Why is my system running but not cooling the house?
- Check the air filter first. A clogged filter blocks airflow across the coil, and when that happens the coil can ice over and the air coming out of the vents turns warm instead of cold. If the filter looks packed with dust, replace it and give the system a few hours to recover. If the filter is clean and the air still is not cold, the system may be low on refrigerant or have a failing part, and that needs a contractor to check with gauges rather than guesswork.
- What can I check before calling for HVAC repair?
- Check the thermostat settings, the batteries in the thermostat if it has any, and the breaker for the furnace or air handler. Check the air filter and replace it if it is dirty, since a blocked filter causes problems that look like bigger issues than they are. Look at the vents around the house and make sure none are closed or blocked by furniture. If the system still is not working after that, tell the contractor what you checked. It saves time on the visit.
