Ten months of work, and storms on top of it
Ardmore only gets a couple months a year when the system can rest. Heat runs November through March, with winter nights averaging 32°F, and cooling runs May through September against afternoons that hit 93°F. That is ten months of the year when either the furnace or the air conditioner has to work, and most homes here heat with electricity, so the strain lands on the same power supply both seasons.
Carter County has seen 40 damaging wind events and 5 winter storms over the past ten years, and a quarter of Oklahoma households lost power for at least 24 hours in 2024. A storm that knocks out power for a day does not just leave you without heat or air. When the power comes back, most systems restart on their own, but whatever was already worn in the furnace or the compressor still has to work through a summer of 93°F afternoons or a winter of 32°F nights.

Oklahoma requires HVAC contractors to hold a state license.
The Construction Industries Board tests and licenses HVAC contractors across the state, Carter County included. That license belongs to the contractor, not to any single job, so it carries over from one repair to the next rather than getting issued fresh each time.
For a repair to your heating and cooling system, that license is what stands behind the work. Oklahoma puts the testing and the record at the state level, not the county, so the same license applies no matter where in Carter County the work happens.

- Why is my heat not working?
- Start with the thermostat and the power to the furnace. If the thermostat screen is blank, check the breaker and any switch that looks like a light switch near the furnace, since that switch turns the whole unit off. If the furnace runs on gas, check that the gas valve is open and the pilot or igniter is doing its job. With most winter lows around freezing here, a furnace that won't stay lit needs a contractor before the next cold night, since the flame sensor or igniter are common failure points and neither is something to force back into working.
- Why is my system running but not cooling the house?
- The system moving air without cooling it usually points to the outdoor unit, not the indoor one. Check that the outdoor condenser fan is spinning and the coil isn't caked in dirt or covered in leaves, since a blocked coil stops the unit from shedding heat. Also pull the filter and hold it up to the light. A clogged filter starves the system of airflow and can ice the indoor coil, which then blows warm air until the ice melts. If the fan runs but the air stays warm after you've checked both, the refrigerant charge or the compressor likely needs a contractor's gauges to diagnose.
- What can I check before calling for HVAC repair?
- Check the thermostat first. Make sure it's set to heat or cool as needed, the batteries aren't dead, and the temperature setting is actually different from the room temperature. Next check the breaker panel for a tripped breaker and the filter for buildup, since a dirty filter causes problems that look like bigger failures. If the system uses gas, confirm the gas valve is open. None of this fixes a failed part, but it rules out the simple causes before a contractor needs to look at the equipment itself.
