Ten months of work, two ways it fails
Your system runs almost year round here. Heat from November through March, cooling from May through September, only a couple months where it can rest. Summer afternoons average 93°F, so the compressor runs long hours to keep up on the hottest days. Winter nights average 34°F, cold enough that the heat runs most of the night too.
Most homes in this area heat with electricity. That ties your heat to the power staying on. A quarter of Oklahoma households lost power for at least 24 hours in 2024, and this area has logged 50 damaging wind events over the past ten years. When the power drops, you find out fast whether your system comes back on its own once it's restored.

Oklahoma requires HVAC contractors to hold a state license.
The license comes from the Construction Industries Board, and it covers the contractor, not the job itself. It stays with that contractor across every house they work in, rather than being issued fresh for each repair.
For a repair on your heating and cooling system, that license is what stands behind the person doing the work. It tells you the state has that contractor on record, and that the repair falls under the same license whether it is a furnace, an air conditioner, or the ductwork between them.

- Why is my heat not working?
- Start with the thermostat. Make sure it is set to heat and set above the room temperature, not just on. If that is fine, check your breaker panel. A furnace that lost power for a moment sometimes needs the switch reset before it will fire again. Gas furnaces have a small igniter or a flame sensor that can fail, and either one will stop the burners from lighting even though the blower still runs. With winter lows around 34°F here, a furnace that will not light is not something to leave for later. A licensed contractor can tell you which part failed and repair it.
- Why is my system running but not cooling the house?
- The blower running without cool air usually points to one of a few things. Check the air filter first. A filter clogged with dust blocks airflow across the coil, and a coil that cannot move enough air will eventually freeze up and stop cooling altogether. If the filter looks fine, check the outdoor unit. The condenser has to be clear of grass clippings, leaves, or anything blocking the fins, or it cannot release the heat pulled from inside the house. If both of those check out and the house still is not cooling on a 93°F afternoon, the system may be low on refrigerant, and that is a repair for a licensed contractor, not something to add on your own.
- What can I check before calling for HVAC repair?
- Check the thermostat first. Confirm it is set to the mode you want, heat or cool, and that the temperature is actually set past the room's current temperature. Next check the breaker panel for a tripped switch, since a system that lost power briefly during a wind event will not always restart on its own. Then check the air filter. A filter that is dirty or clogged restricts airflow and can cause problems on both the heating and cooling side. If the system still is not working after that, the issue is inside the equipment, and a licensed contractor will need to diagnose it.
