Recommended unit for McDonough
Given Georgia’s hot-humid climate and mixed heating, high-seer2 heat pump is the sensible default for most McDonough homes. 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.

What McDonough code requires
Installing or replacing an HVAC system in McDonough follows Georgia rules under the state mechanical code. Here’s what applies statewide:
- PermitRequired
Mechanical permit pulled by your licensed HVAC contractor; covers equipment, refrigerant, and the electrical disconnect.
- SEER2 minimum14.3 SEER2 (Southeast)
Federal Southeast-region minimum for new split-system AC. Higher tiers cut bills and unlock rebates.
- Load calculationRecommended
Sizing by load calc — not rule of thumb — prevents an oversized unit that short-cycles and never dehumidifies.
- RefrigerantR-454B / R-32 (R-410A phased down 2025+)
- 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.
