- SEER2 minimum14.3 SEER2 (Southeast, <45k BTU)
Federal Southeast-region minimum for new split-system AC. Higher tiers cut bills and unlock rebates.
- Load calculationRequired (Manual J)

- RefrigerantR-454B / R-32 (R-410A phased down 2025+)
- Good to know—
Kentucky runs a statewide HVAC licensing, permitting and inspection program (first in the US); a permit plus final inspection is required for every install/replacement, and proof of adequate sizing is required on the permit application.
