Six months of cold puts real strain on a furnace
Your furnace works from November through April here, six months of the year. On winter nights that average 31°F, it cycles on and off for hours at a time to keep the house warm, and every cycle puts wear on the igniter and the burner assembly.
More than half the homes in the area heat with electricity, and Oklahoma sees real outages. About a quarter of households here went at least 24 hours without power at some point in 2024. When the power drops in the middle of a cold snap and comes back on, that is often when a weak igniter or a failing control board finally gives out and the furnace will not restart on its own.

Oklahoma requires HVAC contractors to hold a state license.
The Construction Industries Board tests contractors before they issue this license, and it keeps a record of who holds one. That license belongs to the contractor, not to the furnace or the address, so it covers them across every job rather than being issued fresh each time.
For a furnace repair, the gas connections and burner are the part that can hurt someone if the work is wrong. The state's license is what stands behind the person doing that work, tested and on record with the Construction Industries Board before they ever touch your furnace.

- Why won't my furnace turn on?
- Most of the time it comes down to power, a thermostat setting, or a safety switch that has tripped. Check the thermostat first and make sure it is set to heat and not just fan. If it has a breaker or switch nearby, check that it hasn't tripped, since a lot of furnaces sit on their own circuit. Winter storms here bring wind that can knock power out, and if the power dropped even briefly, some furnaces need the thermostat reset before they fire again. If everything looks right and it still won't start, the igniter or a safety switch inside the unit likely needs a contractor to look at it.
- Why is my furnace blowing cold air?
- If air is moving but it is not warm, the furnace is usually running the fan without the burners lighting. That points to an ignition problem, a flame sensor that needs cleaning, or a safety switch that shut the burners down. A dirty filter can also cause the furnace to overheat and shut off the heating part while the fan keeps running. With lows averaging 31°F here through the winter, this is not something to leave alone, since a furnace stuck on cold air isn't heating the house at all. A contractor can tell you which of these it is once they check the ignition system and the filter.
- Why won't my furnace pilot light stay lit?
- This almost always means the thermocouple, the small sensor that tells the gas valve the flame is lit, has worn out or is dirty. When it can't sense the flame, the gas valve shuts off to be safe, and the pilot goes out. A draft near the pilot or a buildup of dirt on it can cause the same problem. Since homes here rely on heat from November through April, a pilot that won't hold is worth getting looked at quickly rather than relighting it over and over. A contractor can test the thermocouple and replace it if that is the cause.
