Seven months of heat, and storms that knock the power out
Your furnace works from October through April here, with winter nights averaging 28°F from December through February. That is a long stretch of cold nights asking the burner to light and the blower to run, night after night.
More than half of homes in Delaware County heat with electricity, so when the power goes out, the furnace stops with it. That is not rare here. A quarter of Oklahoma households went at least a day without power in 2024, and this area has seen 12 winter storms and 47 damaging wind events over the past ten years. When the power comes back, a furnace that would not start before the outage still will not start after it. If yours is not heating, the cold nights and the storms both play a part.

Oklahoma requires HVAC contractors to hold a state license.
Oklahoma's Construction Industries Board tests contractors before they can hold this license, and it keeps a record of who holds one. That license belongs to the contractor, not to any single job, so the same license that covers a furnace repair covers the other HVAC work that contractor takes on.
For a furnace repair, that license is what stands behind the person working on your gas lines and burner. A bad gas connection is the part of this job that can hurt someone, and the license is the state's way of recording who is qualified to get that connection right.

- Why won't my furnace turn on?
- Most often the thermostat isn't calling for heat the way it should, or power isn't reaching the furnace. Check that the thermostat is set above room temperature and has working batteries if it uses them. Next, check the furnace switch, which looks like a light switch near the unit, and the breaker at the panel. If those are fine and the furnace still won't start, the igniter or a safety switch inside the unit may have failed, and that calls for a contractor to check it.
- Why is my furnace blowing cold air?
- If the air coming out is cold rather than lukewarm, the furnace likely isn't igniting even though the blower is running. A dirty flame sensor is a common cause. The sensor tells the furnace a flame is present, and if it's coated with residue it can shut gas off right after ignition, so the blower keeps moving air that never got heated. A clogged filter can also cause this by starving the burners of airflow. If cleaning or changing the filter doesn't fix it, the flame sensor or gas valve needs a contractor's attention.
- Why won't my furnace pilot light stay lit?
- A pilot light that won't stay lit usually means the thermocouple has worn out. The thermocouple sits in the pilot flame and tells the gas valve the flame is burning. Once it wears out, it can't confirm the flame anymore, so the valve shuts off the gas even though the pilot lit fine a moment ago. A draft blowing across the pilot or a partly clogged pilot orifice can cause the same thing. Since this involves the gas valve, have a contractor check it rather than repeatedly relighting it yourself.
