Arizona requires a contractor-level license through the ROC for all HVAC work, with a 4-year experience requirement and multiple exam components. Individual technicians working under a licensed contractor are exempt from state licensing.
4 years of verifiable experience in the HVAC specialty; or 2 years plus graduation from an approved HVAC course or apprenticeship program
Yes — C-39/CR-39/R-39 trade exam plus Arizona Business Management Exam plus Arizona Statutes and Rules Exam (SRE) through GMetrix. 70% passing score.
Not currently required (licenses renew biennially)
Yes — reciprocity with California, Nevada, and Utah. Applicants with 5+ years of comparable licensure may waive the trade exam but must still pass the Statutes and Rules Exam.
Reciprocity agreements can change. Always verify current status directly with Arizona Registrar of Contractors before relying on reciprocity for licensure.
Arizona licenses contractors only — individual HVAC technicians working under a licensed contractor do not need a personal state license. Reciprocity is relatively flexible compared to many states.
EPA 608 Certification — Required in All 50 States
Regardless of Arizona'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.
