- SEER2 minimum14.3 SEER2 (Southeast)
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—
Louisiana adopts the IMC/IECC under the State Uniform Construction Code; equipment specs and a load calc are typically expected on the permit application, and Gulf-Coast hurricane wind-load anchoring of outdoor condensers is common practice.

Why Furnace Repair Costs Vary in Slidell
Repair costs in Slidell depend on the part needed, labor rates, and whether a permit is required. Older homes (median built 1978) may have outdated systems that are harder to service.

The type of refrigerant (R-454B or R-32 for newer systems) also affects pricing for certain repairs.
