Do HVAC contractors need a license in Arizona?
Yes. In Arizona, a contractor doing heating, air-conditioning, ventilating or refrigeration work needs a contractor license from the registrar of contractors in an air-conditioning and refrigeration classification. Under the registrar’s rules, R-39 covers residential comfort air conditioning, refrigeration, evaporative cooling, ventilating and heating, and C-39 covers commercial work. This is A.R.S. §§ 32-1151, 32-1101; Ariz. Admin. Code R4-9-102, R4-9-103.
