Eleven months of runtime in Lubbock County
Your system works almost year round here. Heat from November through April, cooling from May through September, only one month off. That kind of runtime adds up on the parts that start the system each cycle, the igniter, the capacitor, the contactor.
Winter nights average 29°F, cold enough that the furnace runs long stretches to hold the house steady. Summer afternoons hit 92°F, and the compressor works hardest right when you need it most. Lubbock County has logged 10 winter storms and 150 damaging wind events over the past ten years, and more than half of homes here heat with electricity. When the power goes out in a storm, the system doesn't come back on until it's restored, and Texas households went a full day or more without power at a high rate in 2024. A system already worn from the heat and cold has less room to handle that kind of interruption.

Texas requires HVAC contractors to hold a state license.
The Texas Department of Licensing and Regulation tests contractors before issuing this license and keeps a record of who holds one. That license belongs to the contractor, not to any single job, so the same license covers a repair call in Lubbock County the same way it covers an installation anywhere else in the state.
For a heating and cooling repair, that license is what stands behind the work. TDLR's record is what a contractor's standing here rests on, not the job itself, since Texas licenses the business rather than each repair it does.

- Why is my heat not working?
- The most common cause is the igniter, the thermostat, or a tripped breaker. Furnaces run through a startup sequence, and if the igniter fails to glow or the flame sensor doesn't detect a flame, the system shuts itself down as a safety measure. Check that your thermostat is set to heat and above room temperature, and check your breaker panel for a tripped switch. If those look fine, the furnace has a fault a contractor needs to diagnose.
- Why is my system running but not cooling the house?
- If air is moving but it isn't cold, the most likely causes are a dirty filter restricting airflow, a frozen evaporator coil, or low refrigerant from a leak. A clogged filter starves the coil of airflow, which can cause it to freeze over and stop cooling the air entirely. Check the filter first since that's the one thing you can fix yourself. If it's clean and the air still isn't cold, the system needs a contractor to check refrigerant levels and the coil.
- What can I check before calling for HVAC repair?
- Start with the thermostat. Make sure it's set to the right mode, the temperature is set correctly, and the batteries aren't dead if it's a battery model. Next check your breaker panel for a tripped breaker, and check the air filter since a clogged one can cause both heating and cooling problems. If the outdoor unit isn't running, make sure nothing is blocking it and that it has power. If everything checks out and the system still isn't working right, a licensed contractor can diagnose what's actually wrong.
