What Coeur d'Alene code requires

- SEER2 minimum13.4 SEER2 (North)
Federal North-region minimum for new split-system AC. Higher tiers cut bills and unlock rebates.
- Load calculationRecommended

- RefrigerantR-454B / R-32 (R-410A phased down 2025+)
- Good to know—
Cold-climate sizing matters: much of Idaho is in IECC zones 5-6, so equipment must handle hard winters; permits must be purchased online and a final inspection is typically required.
