Public data, made useful

Local Data

The public record already answers a lot of AC questions. These pages pull the official numbers, show the work, and let you download the data.

  • AC season calendar and live weather

    When the heat arrives, how long it stays, and what today’s dew point means for your AC. Built from the official 1991–2020 climate normals for the New Orleans airport.

    Normals accessed 2026-10-16; live conditions refresh every 10 minutes.

  • HVAC permit explorer

    Every mechanical HVAC permit filed with the City of New Orleans since 2015: volumes by year, the seasonal rush, neighborhood patterns, and when your own AC work needs a permit.
