With a long, hard cooling season here, stepping up the SEER2 tier pays back through lower summer bills. A pro can confirm the right size and system for your home with a load calculation.

Mechanical permit pulled by your licensed HVAC contractor; covers equipment, refrigerant, and the electrical disconnect.
- SEER2 minimum14.3 SEER2 (Southeast)

- Load calculationRecommended
Sizing by load calc — not rule of thumb — prevents an oversized unit that short-cycles and never dehumidifies.

- Good to know—
Georgia follows the IECC-based state energy code; mechanical permits and licensed-contractor installs are required, and Manual J/S sizing is recommended practice but not strictly code-enforced on changeouts.
