Ten months of heat wears a furnace down
Your furnace works from September through June in Centralia. That is ten months a year of the burner lighting, running, and shutting off, on nights that average 31°F through the coldest stretch of winter. Most homes here heat with electricity, so a lot rides on the power staying on and the furnace answering every time it is asked to.
All that cycling puts the load on the same parts. The igniter wears with each start until it can no longer light the burner. The blower motor logs long hours moving air through a house that needs heat most of the year. When one of these gives out, you notice fast. The furnace runs but the air is cool. Or it will not start at all. Or it starts and shuts off again a few minutes later.

Washington requires contractors to register with the state.
That registration puts the contractor's business on file with the Department of Labor and Industries. Nobody tests them on furnace repair to get that number. It tells you the business is on record, not that the state checked their gas work.
For a furnace, the gas connection is the part that matters most, because a bad one is what makes the job dangerous. Washington's registration does not test for that. It confirms the business exists on paper and nothing more.

- Why won't my furnace turn on?
- Most often the thermostat isn't calling for heat the way it should, or the furnace isn't getting power. Check that the thermostat is set below room temperature and has fresh batteries if it uses them. Next look at the furnace switch, which looks like a light switch near the unit, and the breaker in your panel. If those are fine, the igniter or a safety switch inside the furnace may have failed, and that needs a contractor to check.
- Why is my furnace blowing cold air?
- If air is moving but it's not warm, the furnace may be running its fan without the burners lighting. That points to an ignition problem or a flame sensor that's shut the burners off for safety. It can also mean the thermostat fan setting is on rather than auto, which pushes air through the vents even when the furnace isn't heating it. With winter lows here averaging 31°F, this isn't something to leave for long, and a contractor can tell which of these it is.
- Why won't my furnace pilot light stay lit?
- A pilot light that won't stay lit usually means the thermocouple has worn out and is no longer telling the gas valve the flame is present. A draft near the pilot or a dirty pilot opening can cause the same thing. This is a gas safety part, so it should be diagnosed and replaced by a contractor rather than relit repeatedly.
