Summary
Operating as an HVAC contractor in Gulfport, Mississippi requires both state licensing through the Mississippi State Board of Contractors and local registration with the city. Contractors must obtain a Class II HVACR license, which involves passing examinations, demonstrating experience, and maintaining continuing education. The coastal location presents unique challenges including high humidity and salt air exposure that affect equipment selection and installation practices.
