Guthrie asks a lot of a furnace
October through April, seven months of the year, your furnace is what keeps the house livable. On nights averaging 29°F, it is cycling on and off for hours at a stretch, and every start puts a little more wear on the igniter and the parts that get the burner lit.
Logan County has also seen 10 winter storms and 82 damaging wind events over the past ten years, and a quarter of Oklahoma households lost power for at least 24 hours in 2024. When the power drops and comes back, most furnaces restart on their own, but the strain of that many cold nights still catches up with old parts. You notice it as a furnace that takes longer to light, cycles more than it used to, or blows air that is not quite warm enough.

Oklahoma requires HVAC contractors to hold a state license.
Oklahoma licenses HVAC contractors through the Construction Industries Board. That license belongs to the contractor, not to any single job, so the same license that covers a furnace repair in Logan County covers the next one across the state.
For a furnace repair, that state license is what stands behind the work. It is the contractor who is licensed, not the specific repair, so the same credential that qualifies someone to work on a furnace in Logan County qualifies them anywhere else in Oklahoma.

- Why won't my furnace turn on?
- Most of the time it's the thermostat, a tripped breaker, or the switch on the furnace itself, the one that looks like a light switch near the unit. Check that the switch is on and the breaker hasn't flipped before anything else. If those are fine, the igniter may have failed, or a safety switch is holding the furnace off because it sensed something wrong, like a blocked vent or a dirty flame sensor. A furnace won't run through a safety issue, it shuts down instead, so if the basics check out this needs a contractor to find out what tripped it.
- Why is my furnace blowing cold air?
- Air that stays cold once the furnace has been running a few minutes usually means the burners aren't lighting even though the blower is. That points to the igniter, the gas valve, or the flame sensor. If the air only feels cool at first before warming up, that's normal, the furnace runs the blower briefly before the heat exchanger gets hot. With nights averaging 29°F here, a furnace that won't fully heat needs looking at soon rather than waited out.
- Why won't my furnace pilot light stay lit?
- This is almost always the thermocouple, the small sensor that sits in the pilot flame and tells the gas valve it's safe to stay open. When it wears out or sits out of position, the valve shuts the pilot off within seconds. A draft blowing across the pilot or a clogged pilot opening can cause the same thing. A licensed contractor can tell which one it is and replace the part, since Oklahoma requires HVAC work like this to be done under a state license.
