NOAA storm reports for Harris County show 28 hail days and 44 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 2 inches across. Hail flattens the thin aluminum fins on condenser coils and cuts airflow. After a big storm, take a look at the outdoor unit; homeowners insurance often covers the damage. Harris County also had 9 tornado days in that period.
Symptoms Worth a Service Call
- The blower won't stop running
- Banging, squealing or rattling from the furnace
- The burners light, then shut off a few seconds later
- The thermostat calls for heat and nothing happens
- A yellow or flickering flame instead of a steady blue one
What Moves the Price
- Night, weekend or holiday rates
- Which part failed: a flame sensor costs far less than a control board or blower motor
- Whether the part is still under the manufacturer warranty
- The furnace's age and brand, which affect parts availability
- The diagnostic or service call fee

Texas Licensing and Efficiency Rules
Texas is in the DOE's Southeast region, where new split central air conditioners need at least 14.3 SEER2 (13.8 SEER2 for systems of 45,000 BTU/h and up). A repair usually goes ahead without a permit, but the tech handling refrigerant must hold EPA 608 certification. Ask the company for its Texas license or registration number before the visit.
Before You Hire
- Check the filter, the thermostat batteries and the breaker first. Those three cause a surprising number of no-heat calls.
- Have the model and serial number from the furnace label handy. Parts get ordered faster.
- Ask whether the diagnostic fee comes off the repair bill.
