- SEER2 minimum14.3 SEER2 (Southeast)
Federal Southeast-region minimum for new split-system AC. Higher tiers cut bills and unlock rebates.
- Load calculationRecommended

- Good to know—
Virginia uses the statewide Uniform Statewide Building Code (USBC/IECC); local mechanical permits and inspections are required for AC/heat pump/furnace changeouts, and Manual J/S sizing is recommended practice though not strictly enforced.
