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). Most repairs don't need a permit. Anyone who opens the refrigerant circuit does need EPA Section 608 certification, and in Texas the company should carry a state license or registration. Ask for both.
Before You Hire
- Check the filter, the thermostat batteries and the breaker first. Those three cause a surprising number of no-heat calls.
- If the furnace is past 15, ask the tech to price both a repair and a replacement.
- Ask whether the diagnostic fee comes off the repair bill.
