In Shenandoah, Louisiana, AC installation costs typically range from $3,700 to $12,200+ depending on system type and complexity. For a like-for-like central AC replacement, expect $3,700–$7,500; a new central system with ductwork runs $5,600–$12,200+; ductless mini-splits cost $2,800–$7,500; and heat pumps, recommended for this hot-humid climate, range $4,700–$11,200+.

Recommended unit for Shenandoah
Given Louisiana’s hot-humid climate and mixed heating, high-seer2 heat pump is the sensible default for most Shenandoah homes. With a long, hard cooling season here, stepping up the SEER2 tier pays back through lower summer bills. A pro can confirm the right size and system for your home with a load calculation.

What Shenandoah code requires

- PermitRequired
Mechanical permit pulled by your licensed HVAC contractor; covers equipment, refrigerant, and the electrical disconnect.
- 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.
