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

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.
