Best HVAC Schools in New Orleans, LA (2026)

A New Orleans mechanical permit requires load and duct design to be done before the equipment goes in. The city states that Manual J, S and D worksheet calculations shall be completed prior to the installation of an HVAC system on new construction and substantial renovations. Manual J is the heating and cooling load, Manual S the equipment selection against that load, and Manual D the duct design, so on that work the permit is asking for a system that was designed rather than sized by habit.

The building envelope is tested as well, and the city writes the result as a band. Tested air leakage shall be between 5 and 7 air changes per hour at 50 pascals. Most technicians meet air leakage as a ceiling to stay under; New Orleans states a floor too, which matters on a tight new house in a humid climate, where fresh air has to come from somewhere designed for it.

Ducts are tested separately, by individuals certified to perform duct sealing tests, and the test is waived only where the air handler and every duct sit inside conditioned space. Every dwelling unit with forced air heating equipment must also be provided with at least one programmable thermostat. None of these is unusual on its own. Together they make the New Orleans permit a commissioning checklist, and a technician who has never run a Manual J will meet one here.

You get a New Orleans journeyman mechanical license, the Class B license, by passing the International Code Council's National Journeyman Mechanical exam, reported on the ICC's Official Results Report G31, and applying to the city. The city asks that you be 18 or older and submit the completed application, a recent color photo, a driver's license or state ID, and a signed journeyman acknowledgement. The license applies to any person engaged in the trade of installing or repairing equipment, materials or apparatus.

A Class B holder works for someone. The city requires a journeyman mechanic to be employed by and work under the supervision of a Class A air conditioning and refrigeration contractor. Gasfitting runs on a parallel track: a journeyman gasfitter qualifies with a State Plumbing Board natural gasfitter card instead of the ICC exam, and works under a Class A master gasfitter.

The license costs $55 a year, half the $110 the master license costs. It expires on the holder's birthday rather than on a fixed date, renewal opens 90 days before, and a late renewal adds $5 for each month it is overdue. The exam the city names is the thing a training program here should be preparing you for, because it is what turns a graduate into a licensed New Orleans technician.

HVAC techs in the New Orleans metro make a median of $63,500 a year, which is $4,850 above the Louisiana median of $58,650 and $2,490 above the national median of $61,010. The hourly median is $30.53. New Orleans is the best-paying part of Louisiana for this trade, though on a workforce of only 1,280.

The shape of the range is unusual. The mean is $60,970, below the median, which means the middle of the market is paid better than a simple average suggests and the top is not pulling it up. The bottom tenth earn $38,300 or less, the middle half falls between $46,790 and $70,640, and the top tenth earn $81,610 or more, about $13,600 below the national 90th percentile of $95,210.

These figures come from the Bureau of Labor Statistics wage survey of May 2025 for occupation 49-9021, covering the New Orleans-Metairie metropolitan area, which takes in Orleans, Jefferson, St. Tammany, St. Bernard, St. Charles, St. John the Baptist and neighboring parishes. The survey reports what people earn, not why, and it makes no forecast about hiring.
