Recommended unit for Gretna
Given Louisiana’s hot-humid climate and mixed heating, high-seer2 heat pump is the sensible default for most Gretna 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.

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

- 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.
