Arizona HVAC Exam Prep: 1,450 Practice Questions for the ROC Air Conditioning and Refrigeration Contractor Exams
PassProfessor’s Arizona HVAC Exam Prep is built for candidates for the Arizona Registrar of Contractors (ROC) air conditioning and refrigeration classifications – C-39, R-39R, and CR-39, and the including-solar R-39, C-79, and CR-79. The bank holds 1,450 original practice questions: a 1,250-question HVAC core covering the trade itself, plus 200 Arizona questions on Arizona statutes and rules (the SRE material) and the PSI trade exam’s published content areas.
Every question is an original item written for this program, and every question comes with an explanation for every answer: why the keyed answer is right and why each other option is wrong, grounded in the cited code, standard, manual, or rule.
The exam, in facts
- Arizona licenses the business, not the individual: the ROC license belongs to the contracting entity and is held through a qualifying party. Chapter 10 creates no journeyman, technician, apprentice, or master license class for HVAC work.
- The PSI trade exam is one sitting for the whole 39/79 family: 80 questions, 70% to pass, 210 minutes. It is open book only in a narrow sense – the only references allowed in the center are the OSHA selections and the listed code books, IMC 2018 and IFGC 2018.
- PSI’s published trade outline: Refrigeration 12 – Air Conditioning 12 – Warm Air Heating 12 – Controls and Motors 8 – Boilers 4 – Ventilation 4 – Evaporative Coolers 4 – Fuel Piping Systems 5 – Water Piping Systems 5 – Steam, Hot, Chilled, and Condensing Water 5 – Testing, Balancing, and Inspections 5 – Sizing and Estimating 4.
- Arizona pairs the trade exam with the Statutes and Rules Exam (SRE) – a computer-based, open-book training course and exam the ROC itself provides online through GMetrix for $61. The including-solar classifications add a separate 30-question solar exam (70% to pass, 75 minutes).
- A qualifying party needs 4 years of practical or management trade experience, at least 2 of them within the last 10 years; credited technical training may cover at most 2 of the 4 years. The PSI trade exam fee is $66 for one examination.
- Licenses run on a 2-year (biennial) cycle and Arizona imposes no ROC continuing-education requirement. Specialty bond amounts scale with annual volume – specialty commercial from $2,500 (under $150,000 of volume) to $50,000 ($10,000,000 and over) – and residential and dual licensees carry an added $200,000 bond or Recovery Fund protection.
How the practice program works
The full practice exam draws 80 questions in 210 minutes – the same length and time as the real trade exam – weighted to PSI’s published outline across the bank’s 17 topics, and every attempt draws a fresh assortment, so no two practice exams are the same.
Each of the bank’s 17 topics has its own drill, so you can drill Arizona law and SRE material on its own or work the trade topics one at a time:
- Refrigeration Principles & Components — 129 questions
- Refrigerants, Recovery & Handling — 55 questions
- Cooling Systems: Service, Diagnostics & Repair — 111 questions
- Heating Systems — 227 questions
- Air Distribution, Duct Design & Airflow — 114 questions
- Controls & Electrical for HVAC — 120 questions
- Piping, Brazing & Gas Piping — 73 questions
- Ventilation, Venting, Combustion Air & IAQ — 93 questions
- Load Calculation & System Design — 46 questions
- Safety, Testing & Code Practice — 92 questions
- Commercial Refrigeration Systems — 41 questions
- Equipment Installation & Commissioning — 75 questions
- Hydronics & Boilers — 49 questions
- Business & Law Practice — 50 questions
- Plan Reading & Construction Documents — 25 questions
- Packaged & Manufactured Systems — 50 questions
- Arizona Licensing Law & Rules — 100 questions

Questions
Which Arizona classifications does this cover?
The ROC air conditioning and refrigeration family: C-39 (commercial), R-39R (residential), and CR-39 (dual), plus the including-solar R-39, C-79, and CR-79. All six share one PSI trade exam and one published outline; the solar classifications add the separate 30-question solar exam, and new applicants also complete the ROC’s SRE course and exam, which the Arizona portion of this bank covers.
Is the practice exam timed like the real one?
Yes. The full practice exam allows 210 minutes for 80 questions, matching the PSI trade exam. The real exam allows only the OSHA selections and the 2018 code books in the center; how you use references while practicing is up to you.
Are these real exam questions?
No. Every question is original to PassProfessor, written from PSI’s published exam outline and the cited references. Nothing here is copied or paraphrased from a licensing exam or a competitor’s bank.
