North Carolina Licensing and Efficiency Rules
North Carolina 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 North Carolina the company should carry a state license or registration. Ask for both.
