- 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)
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—
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.

Kentucky's permitting requirements add $50–$150 to the job, and the shift to R-454B or R-32 refrigerant (R-410A phased down after 2025) may increase costs for older units needing recharge. Labor rates are moderate, reflecting Franklin's tier 4 status.
