Mississippi requires a Mechanical Contractor license above specific project value thresholds ($10,000 residential, $50,000 commercial). Unusually, it requires completed project references rather than minimum hours of experience.
No minimum years of experience required. Applicants must provide proof of 3 completed jobs in the classification requested and submit 3 reference letters.
Yes — Mechanical Contractor exam: 100 questions, 4-hour limit, open book. Must pass both a law/business exam and general HVAC trade exam. 70% passing score.

Yes — Mississippi has reciprocity with Alabama. Florida's CILB also has a reciprocity agreement with Mississippi.
Reciprocity agreements can change. Always verify current status directly with Mississippi State Board of Contractors before relying on reciprocity for licensure.
Mississippi's lack of minimum experience requirement (using references and completed jobs instead) is unusual compared to most states. The dollar-value thresholds mean small service calls under $10,000 don't legally require a state license.
EPA 608 Certification — Required in All 50 States
Regardless of Mississippi's state licensing rules, any technician who purchases, handles, or works with regulated refrigerants must hold EPA Section 608 certification. This is a federal requirement under the Clean Air Act that no state law can waive. EPA 608 Universal (covering Type I, II, and III) is the most versatile credential for most HVAC roles.
