Metairie Weather and HVAC Load
NOAA's 1991-2020 climate normals put Metairie at 1,176 heating degree days and 3,205 cooling degree days per year. Cooling carries most of the load, which is why compressors and condenser fan motors wear out faster here than in northern cities. A normal year brings 5 nights at or below freezing and 85 days over 90°F. 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.

Metairie Housing Stock
Half the homes in Metairie were built before 1972 (Census ACS median), so the typical house is about 54 years old. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. Owners live in 61.8% of occupied homes, roughly 38,000 households. The median home value is $308,900, and median household income is $73,256. We use both figures to adjust labor and pricing for this page.
NOAA storm reports for Jefferson Parish show 6 hail days and 13 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 1.25 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. Jefferson Parish also had 6 tornado days in that period. In Metairie, 21.3% of residents are 65 or older. For older adults, a house with no heat in January or no AC during a heat wave is a medical risk. Mention it when you call, since many companies put those calls first.

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). Expect the contractor to pull a mechanical permit for a replacement job in Metairie. If a bidder suggests skipping it, move on. Also ask for a 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
- If winter nights regularly drop below 10°F, pay for a cold-climate model.
- Rinse the indoor filters once a month during heavy use.
- Most mini-splits qualify for utility heat pump rebates, so check before you buy.
