Muskogee County runs its system almost year round
Your furnace works October through April, then the AC takes over for May through September. Almost the whole year, one system or the other is running. Winter nights average 31°F, cold enough that the burner cycles on and off for hours through the night. Summer afternoons hit 91°F, and the compressor runs long stretches trying to keep up.
More than half of homes here heat with electricity, so a storm that knocks out power leaves the house with no heat at all until it's back. Oklahoma households often go a full day or more without power after weather like this, and Muskogee County has logged 10 winter storms and 73 damaging wind events over the past ten years. Most systems restart on their own once power returns, but that many hard freezes and outages add up to real wear on the parts that keep the system running the rest of the year.

Oklahoma requires HVAC contractors to hold a state license.
The Construction Industries Board issues that license, and it goes with the contractor, not the job. That means the same license covers a furnace, an air conditioner, or the ductwork between them, whatever the repair is.
For a heating and cooling repair, that state license is the credential doing the work of accountability here. If gas is part of the job, the dangerous part is a bad connection, and the state license is what stands behind the person making it.

- Why is my heat not working?
- Start with the thermostat and the breaker before you assume the worst. If the thermostat is set to heat and the temperature is set above room temperature, check the breaker panel for a tripped switch. A furnace that runs on electric ignition will not light if the flame sensor is dirty or the igniter has failed, and a gas furnace will not light at all if the gas valve was shut off. If your home heats with electricity, like most homes here do, a tripped breaker or a failed heating element is a common cause. Winter nights average 31°F here, so a furnace that will not run needs attention quickly.
- Why is my system running but not cooling the house?
- The system running but not cooling usually points to airflow or refrigerant, not the thermostat. Check the filter first. A filter clogged with dust chokes airflow across the coil, and a coil that cannot move enough air can freeze up and stop cooling even though the blower keeps running. If the filter is clean and the vents are open, the problem is more likely low refrigerant or a failing compressor, and that calls for a licensed contractor to check the pressures. With afternoons here reaching 91°F, a system that runs without cooling needs a look soon.
- What can I check before calling for HVAC repair?
- Check the thermostat settings, the batteries in the thermostat if it has any, and the breaker for the system. Replace the filter if you cannot remember the last time it was changed. Look at the outdoor unit and clear away any leaves, grass or debris blocking the sides. If the system still is not working after that, a licensed contractor can diagnose what the checks cannot catch. Oklahoma requires HVAC contractors to hold a state license, and that license covers the diagnosis and repair work your system needs.
