Georgia Licensing and Efficiency Rules
Georgia 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 Georgia the company should carry a state license or registration. Ask for both.
Before You Hire
- Maintenance plans often put members first in line for emergency calls.
- Keep space heaters away from curtains and bedding, and never heat the house with a gas oven.
