Seven months of heat, and storms that knock the power out
Your furnace works from October through April here, seven months of the year. On nights that average 30°F through December through February, it cycles on and off for hours at a time. Every cycle puts a little more wear on the igniter and the ignition control board. That's usually where trouble shows up first, a furnace that won't light, or lights and then shuts back down.
Oklahoma County has seen 15 winter storms and 253 damaging wind events over the last ten years. Storms like that knock out power. Across Oklahoma, a quarter of households went at least 24 hours without it in 2024. Most furnaces need electricity to run the blower and controls even though they burn gas, so when the power drops, so does your heat.

A new furnace would cut about $100 a year off heating for a typical Oklahoma County home.
Estimates for a typical Oklahoma County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Oklahoma fuel prices and NOAA climate normals. Your home will differ.
Repair makes sense when one part has failed and the heat exchanger is sound.
Replacement makes sense when the heat exchanger is cracked or the furnace keeps needing parts.
Oklahoma requires HVAC contractors to hold a state license.
The Construction Industries Board licenses HVAC contractors in Oklahoma. The board tests the contractor and keeps them on file, and that license covers the contractor as a whole, not each job they do.
For a furnace repair, that license is what stands behind the work. A bad gas connection is the dangerous part of a furnace repair, and the license is what accounts for the person doing it. In Oklahoma County, 58.5% of homes heat with gas, so a furnace repair here is often gas work covered by that same license.

- Why won't my furnace turn on?
- Start with the thermostat. Make sure it's set to heat and the setpoint is above room temperature, since a setting bumped a degree or two can look like a dead furnace. Next check the power switch on or near the furnace, and the breaker it runs on. If those are fine, the igniter may have failed, or a safety switch may be holding the furnace off because of a clogged filter or a blocked vent. A furnace won't run if it senses a problem, so it's doing what it's supposed to do. A contractor licensed by the Construction Industries Board can find which of these it is.
- 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, a gas supply issue, or a safety switch shutting the burners down after they try to light. It can also mean the thermostat fan is set to "on" rather than "auto", which pushes air through the ducts even when the furnace isn't heating it. With lows around 30°F overnight here in the winter, a furnace stuck like this needs a look soon rather than later.
- Why won't my furnace pilot light stay lit?
- This usually comes down to the thermocouple, the small sensor that tells the gas valve the pilot is actually burning. When it wears out or sits out of position, the valve shuts the gas off within a minute or so of lighting, even though the flame looked fine. A draft blowing across the pilot or a dirty pilot orifice can cause the same thing. Either way it's a gas valve issue, not something to keep relighting on your own. Most newer furnaces don't use a standing pilot at all, so if yours does, it's worth having a licensed contractor check it before the coldest stretch of the season.
