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
- Have the model and serial number from the furnace label handy. Parts get ordered faster.
- 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.
