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). A repair usually goes ahead without a permit, but the tech handling refrigerant must hold EPA 608 certification. Ask the company for its Georgia license or registration number before the visit.
Before You Hire
- Ask what the emergency fee is before the truck is sent.
- Keep space heaters away from curtains and bedding, and never heat the house with a gas oven.
- If the CO alarm goes off, get everyone outside and call 911 or the gas company before you call an HVAC company.
