- SEER2 rating and whether the compressor is single-stage or variable-speed
- Electrical work such as a new disconnect, breaker or wiring

Georgia Permits, Efficiency Rules and Rebates
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). Plan on a mechanical permit for most replacements in Macon-Bibb County; the contractor normally pulls it. Before you sign, ask each bidder for their Georgia license or registration number and proof of insurance. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.
Before You Hire
- Ask what federal, state or utility incentives apply to the model you're quoted.
- Fall and early spring installs often come with better pricing and shorter waits.
- Buy the condenser and coil as a matched set, or you may void the manufacturer warranty.
