New Orleans Weather and HVAC Load
In a normal year, New Orleans racks up 1,134 heating and 3,291 cooling degree days (NOAA 1991-2020 normals). Cooling carries most of the load, which is why compressors and condenser fan motors wear out faster here than in northern cities. On average, New Orleans gets 2 freezing nights and 86 days above 90°F per year. On the cooling side, a 2,000 sq ft house here usually needs around 4 tons. A tight, well-insulated house may get by with half a ton less.

New Orleans Housing Stock
The median New Orleans home dates to 1959, according to the Census ACS. That makes the typical house about 67 years old. Houses that old often still have duct runs sized for an old coal or oil furnace and 60- or 100-amp electrical panels. Both can add cost when new equipment goes in. Owners live in 50.5% of occupied homes, roughly 78,000 households. The median home value is $296,400, and median household income is $55,339. We use both figures to adjust labor and pricing for this page.
NOAA storm reports for Orleans Parish show 2 hail days and 17 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 1 inches across. Storms here are more likely to cause power surges than coil damage, so a surge protector on the outdoor unit is worth the small cost. Orleans Parish also had 3 tornado days in that period.

Louisiana Permits, Efficiency Rules and Rebates
Louisiana is in the DOE's Southeast region, where new split central air conditioners need at least 14.3 SEER2 (13.8 SEER2 for systems of 45,000 BTU/h and up). Plan on a mechanical permit for most replacements in New Orleans; the contractor normally pulls it. Before you sign, ask each bidder for their Louisiana license or registration number and proof of insurance. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.
Before You Hire
- Rinse the indoor filters once a month during heavy use.
- Multi-zone systems cost more per room, but they run off a single outdoor unit.
- If winter nights regularly drop below 10°F, pay for a cold-climate model.
