About the AZ HVAC Exam
The Arizona HVAC contractor exam is the 80-question PSI R-39R/C-39 (CR-39) Air Conditioning and Refrigeration trade exam, taken alongside the AZ Statutes and Rules Training Course and Exam (SRE). It covers the residential R-39R, commercial C-39, and dual CR-39 classifications; the solar-inclusive R-39/C-79/CR-79 classifications add a separate 30-question solar exam. Four years of experience are required.

Frequently Asked Questions
Is the AZ HVAC vocabulary game free?
Yes. The game is free to play with no sign-up. Signing in adds AI explanations for any term.
How do the AZ HVAC vocabulary games work?
There are 4 games built on 20 AZ HVAC terms. In Guess the Term, a clue describes one term and you have six tries to spell it, with green, yellow and gray letters showing how close you are. In Term Match, six terms appear as colored tiles; swap neighbors to line up three or more of the same term, and each match shows what the term means. In Term Pairs, twelve face-down cards hide six pairs of terms; flip two at a time to find each pair, and every pair you find shows what the term means. In Term Search, five terms hide in a grid of letters, reading across, down or diagonally; drag across a term to circle it, and each term you find shows what it means.
Where do the AZ HVAC terms come from?
OpenExamPrep researched each term from the Arizona Registrar of Contractors (ROC) content outline and primary sources, listed under Sources on this page. The game is independent study material, not an official exam resource.
What are the Arizona HVAC license classifications?
The Arizona ROC issues R-39R Air Conditioning and Refrigeration (residential), C-39 Air Conditioning and Refrigeration (commercial), and CR-39 (dual, combining C-39 and R-39R). Adding solar work requires R-39, C-79, or CR-79, which are the same classifications 'Including Solar.' All applicants pass the AZ Statutes and Rules Exam plus the PSI trade exam; the solar classifications add a separate 30-question solar exam.
How much experience do I need for an Arizona HVAC license?
A.R.S. 32-1122(B)(1) requires the qualifying party to have at least 4 years of practical or management trade experience in the classification applied for, at least 2 years of which must fall within the last 10 years. Technical training at an accredited college or university, or in a manufacturer's accredited training program, may substitute for no more than 2 of the 4 years.
