The City of New Orleans administers Stationary Engineer's Licenses for qualifying mechanical and stationary equipment work within its jurisdiction.
The Second Class Stationary Air Conditioning credential is associated with the examination requirements established by the City of New Orleans.
Organizing your preparation and application documents early can make the licensing process more manageable.
The Louisiana (New Orleans) Second Class Stationary Air Conditioning examination is associated with a City of New Orleans licensing classification rather than a general statewide HVAC license.
The City requires qualifying applicants to submit an application package and official passing ICC examination results.
Required application documents include the Stationary Trade License Application, government-issued photo identification, and an applicant photograph meeting the City's requirements.
The City reviews submitted applications before scheduling an in-person appointment for license processing.
New Orleans Stationary Engineer's Licenses are subject to annual renewal. License holders must follow the City's applicable renewal procedures.
Professionals working with stationary air conditioning equipment should understand their responsibilities involving equipment safety, mechanical compliance, operating procedures, maintenance, and appropriate supervision.
These responsibilities make technical preparation valuable beyond the examination itself.
The following publications support preparation for the Louisiana ICC Second Class Stationary Air Conditioning examination.
These two publications complement one another during preparation. The International Mechanical Code provides installation and safety requirements, while Modern Refrigeration and Air Conditioning explains the technical principles behind refrigeration and cooling equipment.
Using both resources alongside practice questions encourages a stronger understanding of stationary air conditioning systems and examination-related concepts.
