Enid runs its system almost year round
Your furnace works October through April here, and the air conditioner takes over May through September. That is almost the whole year with one or the other running. Winter nights averaging 27°F mean long heating cycles night after night, and the igniter and heat exchanger take the wear. Summer afternoons averaging 93°F push the compressor hard for five straight months, and that is where a system in Enid tends to fail first.
Garfield County has also seen 12 winter storms and 109 damaging wind events over the past ten years, and a quarter of Oklahoma households lost power for at least 24 hours in 2024. A furnace or air conditioner that cuts out with the power does not always come back on its own, and that is worth knowing before the next outage.

A new furnace and air conditioner would cut about $160 a year off heating and cooling for a typical Garfield County home.
Estimates for a typical Garfield County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Oklahoma fuel prices and NOAA climate normals. Your home will differ.
Repair makes sense when one part has failed.
Replacement makes sense when the furnace's heat exchanger is cracked, the air conditioner's compressor has failed, or repairs keep coming.
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 the job itself, so it covers the company across every repair it takes on, not just this one.
For a repair on your heating and cooling system, that license is what stands behind the person doing the work. The Board is the one that tested them and the one that can answer for their record.

- Why is my heat not working?
- Most no-heat calls come down to the thermostat, the igniter, or the flame sensor. On gas furnaces, which heat most homes here, the igniter has to glow hot enough to light the burners. A weak or cracked igniter will fail to start the flame at all. A dirty flame sensor can also shut the furnace down mid-cycle because it reads no fire even though there is one. Check that the thermostat is set to heat and the batteries are good before anything else. If the furnace tries to start and then shuts off, or does not respond at all, a contractor will need to test the igniter, the sensor, and the control board to find which one failed.
- Why is my system running but not cooling the house?
- If the blower is running but the air is not cold, the most common causes are a dirty filter, low refrigerant, or a frozen evaporator coil. A clogged filter blocks airflow across the coil. When the coil cannot get enough air, it can freeze over instead of cooling. Low refrigerant does something similar. It leaves the coil too cold, and it frosts up rather than pulling heat from the air. On a 93°F afternoon here, either problem shows up fast because the system is already working at its limit. Check the filter first. If it is clean and the air still is not cooling, the system likely has a refrigerant leak or a coil problem that needs a contractor to diagnose.
- What can I check before calling for HVAC repair?
- Start with the thermostat. Make sure it is set to heat or cool as needed, the batteries are fresh, and the display is responding. Next check the air filter. A filter clogged with dust restricts airflow and can cause both heating and cooling problems, so replace it if you cannot remember the last time it was changed. Check that the breaker for the furnace or air conditioner has not tripped. If the outdoor unit is not running, make sure nothing is blocking it. These checks take a few minutes and rule out the simplest causes. If the system still is not heating or cooling right after that, a licensed contractor will need to look at it.
