Understanding the AZ-ACR Testing Calendar
If you searched "AZ-ACR exam dates 2026" expecting a list of quarterly testing windows, here's the good news: the Arizona R-39R/C-39 (CR-39) Air Conditioning and Refrigeration examination doesn't work that way. This is a PSI Services LLC-administered, computer-based trade examination that Arizona candidates can schedule on demand, rather than a paper-and-pencil exam offered on a handful of set dates per year. That means your real planning task isn't finding an open "date" on a calendar - it's managing eligibility timing, fee sequencing, and retake waiting periods correctly so you don't waste money or lose momentum.
The Arizona Registrar of Contractors (ROC) sets the licensing requirements, while PSI runs the actual test delivery - both the trade content exam and the separate online Arizona Statutes and Rules Exam (SRE). Because scheduling is candidate-initiated rather than tied to a published testing season, the practical "deadlines" that matter most are the ones baked into the rules: how soon you can retest after a fail, and how long your passing score remains valid for licensing purposes.
How Scheduling Actually Works With PSI
Once you're ready to book, you'll be scheduling directly through PSI, choosing either a test-center appointment or a remote-proctored session. Both delivery formats use the same computer-based multiple-choice format, the same 80-question, 210-minute structure, and the same 70% passing threshold. PSI may also insert 5-10 unscored experimental questions into your session - these are indistinguishable from scored questions, so pace yourself as though every question counts.
Two separate fees apply, and they are not bundled:
- Trade examination (R-39R/C-39): $66 per attempt
- Arizona Statutes and Rules Exam (SRE): $61, taken online as a separate requirement
Because these are independent line items, plan your scheduling sequence deliberately. Some candidates prefer to lock in the SRE first since it's shorter and administered entirely online, then shift full attention to the trade content. Others tackle the trade exam first while technical material is freshest. Either order is acceptable - what matters is that you budget for both fees and don't assume one covers the other.
Key Takeaway
Treat the $66 trade exam and $61 SRE as two separate scheduling and study events, not one combined appointment.

Retake Waiting Periods and Deadlines to Track
The single most important "date" mechanic in this exam isn't a testing window - it's the mandatory waiting period between attempts. Missing this timing doesn't just cost you a rescheduling headache; it can push your entire licensing timeline back by months if you're not tracking it deliberately.
- Attempts 1-3: A candidate who does not pass must wait 30 days before retesting.
- Attempt 4 and beyond: The waiting period jumps to 90 days.
This structure rewards focused first-attempt preparation. A candidate who treats early attempts casually, assuming they can "just retake it in a month," may find themselves facing a 90-day gap after a third miss - a significant delay if you're trying to qualify for a contractor license on a project timeline. This is exactly why realistic self-assessment before your first scheduled date matters so much; see How Hard Is the AZ-ACR Exam? Complete Difficulty Guide 2026 for an honest look at where candidates typically struggle.
Eligibility Timing: Experience and Results Validity
Scheduling isn't just about the exam date itself - it's also about whether you're eligible to sit for it and whether your result will still be usable when you apply for licensure.
Experience Requirements Before You Schedule
The qualifying party on an Arizona contractor license application ordinarily needs four years of practical or management trade experience, including two years within the preceding ten years. Qualifying technical training can substitute for up to two of those four years. If you're unsure whether your work history or training satisfies this threshold, confirm it before you spend money on a scheduling fee - a full explanation is available in AZ-ACR Requirements 2026: Eligibility, Prerequisites & How to Qualify.
The Two-Year Results Window
Passing the exam is not a permanent credential sitting in a file somewhere - your exam results must fall within the two years preceding your license application to the ROC. This means the "date" that actually matters most is the gap between when you pass and when you submit your application paperwork. Candidates who pass early but delay their application for personal or business reasons need to watch this window closely, since a stale result may force a retest even though nothing about their competency has changed.
Key Takeaway
Don't pass the exam and then sit on your application for years - your result expires for licensing purposes after two years.
Once licensed, remember that Arizona contractor licenses renew on a biennial cycle, with license fees and bond obligations handled entirely separately from the exam fees discussed here.
What to Expect on Exam Day
Regardless of when you schedule, the exam-day mechanics are fixed by PSI's general candidate bulletin and the trade outline (last revised June 8, 2023). Knowing these details in advance prevents last-minute surprises that can derail an otherwise well-prepared candidate.
- Format: Computer-based, multiple choice, delivered at a test center or via remote proctoring.
- Length and structure: 80 scored questions plus up to 5-10 unscored experimental items, within 210 minutes.
- Passing score: 70%. For the exact scoring math, see AZ-ACR Passing Score 2026: Exactly What You Need to Pass.
- Calculator: A silent, nonprinting, nonprogrammable, nonscientific calculator is permitted.
- References: Open-book access to OSHA 29 CFR Part 1926 (or PSI's approved selections with current amendments), the 2018 International Fuel Gas Code, and the 2018 International Mechanical Code.
- Annotation rules: Advance highlighting, underlining, annotations, and permanent tabs in your approved references are allowed. Loose extra papers and in-test writing in references are not.
- Remote-specific restrictions: No scratch paper and no breaks during remote-proctored sessions - plan your bathroom and hydration timing accordingly.
Building a Study Timeline Around the Domains
Because there's no fixed testing window forcing your hand, you control your own runway. Use that flexibility deliberately by mapping study weeks to the exam's actual question allocations rather than studying everything equally. A generic weekly template wastes this advantage - instead, weight your weeks the way PSI weights the exam.
Refrigeration & Air Conditioning
- These two domains are jointly the largest, at 12 questions each
- Master refrigerant cycle fundamentals, system components, and cooling-load logic before moving on
Warm Air Heating
- Also weighted at 12 questions - equal priority to refrigeration and cooling
- Focus on furnace types, combustion, and heat distribution scenarios
Controls and Motors
- 8 questions - the next-largest single block
- Drill electrical control sequencing and motor troubleshooting scenarios
Mid-Weight Domains
- Fuel Piping, Water Piping, Steam/Hot/Chilled/Condensing Water, and Testing/Balancing/Inspections - 5 questions each
- Cross-reference the 2018 International Fuel Gas Code and 2018 International Mechanical Code while these topics are fresh
Lighter Domains & Full Review
- Boilers, Ventilation, and Evaporative Coolers (4 questions each) plus Sizing and Estimating (4 questions)
- Run full-length timed practice on the AZ-ACR practice test platform to simulate the 210-minute session

Which Domains Deserve Priority Scheduling
The trade outline assigns exact question counts to all 12 domains: 12, 12, 12, 8, 4, 4, 4, 5, 5, 5, 5, and 4 questions respectively. That's not a rough estimate - it's the official allocation, and it should directly shape how much study time you schedule before booking your exam date.
Refrigeration, Air Conditioning, Warm Air Heating
These three domains are the joint-largest subject areas on the exam, each carrying 12 questions. Together they represent well over a third of the entire test.
- Do not shortchange any one of the three in favor of the others - they're weighted identically
- Original trade scenarios in these areas often blend system diagnosis with code or sizing logic
Controls and Motors
At 8 questions, this is the next heaviest single domain after the top three.
- Expect scenario-based questions on control sequencing and motor operation, not just terminology recall
Sizing and Estimating
Weighted at 4 questions, this domain still requires comfort navigating your open-book references quickly under time pressure.
- Practice locating sizing tables in your approved references before exam day, not during it
