Why New Orleans needs cooling

New Orleans records the highest sustained dew points of any major American city — summer air that AC systems must wring gallons of water from daily. Add hurricane exposure, high water tables and historic housing, and NOLA installs are among the most specialized in the country.

Summer humidity: extreme (highest dew points in the US).

New Orleans homes & buildings

Shotgun houses, Creole cottages and double-gallery homes — most raised on piers, many historic — define the city, alongside slab construction in Metairie and the newer East. Raised homes ease duct access but expose ductwork to humid crawl air; sealing and insulation quality decide whether systems keep up.

Installing in New Orleans: what to know

Historic District Landmarks Commission review applies to visible equipment in the French Quarter, Marigny and Garden District — side/rear placement passes, street-visible doesn't. Condensers must be elevated for flood in much of the city (post-Katrina code), and hurricane strapping is mandatory. Entergy offers efficiency incentives.

New Orleans, LA installation FAQs

What AC works best in a New Orleans shotgun house?

Mini-splits have become the shotgun standard: no duct space exists in the classic layout, and a head per room (or one per two rooms) delivers zoned cooling without butchering historic fabric. HDLC-compliant condenser placement on the side or rear keeps the streetscape clean and the commission happy.

Why must New Orleans condensers be elevated?

Flood code: much of the city requires equipment at or above base flood elevation, on platforms or raised stands, so a storm-surge or heavy-rain event doesn't total the most expensive component. Combined with hurricane strapping, it's a $500–$1,200 add that insurance and code both expect.
