Eleven months of work, most of it in hard weather
Your system runs almost all year here. Heat from November through April, cooling from May through September, only one real month off in between. Winter nights average 31°F, cold enough that the burner or the heat pump cycles on and off for hours at a stretch. Summer afternoons hit 94°F, and the compressor runs long stretches just to keep up. That much runtime wears on the parts that start the cycle, the igniter, the contactor, the capacitor, and those are usually the first things to fail.
More than half the homes here heat with electricity, so when the power goes out, the heat goes out too. Comanche County has seen 14 winter storms and 148 damaging wind events over the past ten years, and a quarter of Oklahoma households lost power for at least a day in 2024. A storm knocks the power out, the system stops, and when the power comes back it has to be able to restart on its own.

Oklahoma requires HVAC contractors to hold a state license.
The Construction Industries Board tests contractors before they can hold this license, and it keeps a record of who holds one. That license belongs to the contractor, not to any single job, so the same license that covers a repair in Lawton covers the next contractor's work in Duncan.
For a repair to your heating and cooling system, that state license is what stands behind the person in your house. Oklahoma tested this contractor and has a record of them before they touched your system, and that record does not reset from one job to the next.

- Why is my heat not working?
- Start with the thermostat and the power to the furnace before you assume the worst. Check that the thermostat is set to heat and a few degrees above room temperature, and check the breaker for the furnace hasn't tripped. If you have a gas furnace, look at the igniter through the viewing window when it calls for heat. A furnace that clicks a few times and shuts off is usually failing to sense a flame, and that points to a worn igniter or a dirty flame sensor. If you heat with electricity, a tripped breaker or a bad heating element can leave the blower running with no warm air coming out. Either way, a contractor licensed by the Construction Industries Board can find which one it is.
- Why is my system running but not cooling the house?
- The system is running but something between the coil and the room is stopping the cold air from doing its job. A dirty filter is the first thing to check. A blocked filter starves the coil of airflow and can cause it to freeze over. If the outdoor unit is running but the air inside is warm, low refrigerant or a failing compressor could be the cause, and that needs a licensed contractor to check with gauges. With summer afternoons here averaging 94°F, a system losing cooling capacity shows itself fast, so don't wait on it.
- What can I check before calling for HVAC repair?
- Check the thermostat first. Make sure it's set to the right mode and the batteries aren't dead. A thermostat that's lost power looks exactly like a dead system. Next check the breaker panel for a tripped breaker on the furnace or the outdoor unit. Then pull the filter and hold it up to a light. If you can't see light through it, replace it. A clogged filter is behind a lot of no-heat and no-cool calls. If the system still isn't working after that, a licensed contractor can diagnose what's left.
