What Lewisville code requires

- PermitRequired
Mechanical permit pulled by your licensed HVAC contractor; covers equipment, refrigerant, and the electrical disconnect.
- SEER2 minimum14.3 SEER2 (Southeast, split systems <45,000 BTU)
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—
NC follows the NC State Building Code (Mechanical/Energy); residential changeouts require a mechanical permit and ACCA Manual J/S/D sizing is the referenced recommended practice but not strictly enforced on like-for-like swaps.
