Between 2020 and 2025, NOAA's Storm Events Database logged 11 hail days and 52 days with damaging thunderstorm winds in Fulton County. The largest hail reported was 1.75 inches across. Hail flattens the thin aluminum fins on condenser coils and cuts airflow. After a big storm, take a look at the outdoor unit; homeowners insurance often covers the damage. Fulton County also had 3 tornado days in that period.

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
- If you see ice, shut the system off. Running it frozen can kill the compressor.
- Swap the air filter and check the breaker before you call anyone.
- If the compressor is gone on an older unit, get a replacement quote before you pay for the repair.
