Arizona is one of the hotter HVAC markets in the country — literally. Phoenix's extreme heat means HVAC systems run year-round, demand is high, and the licensing process rewards contractors who are prepared. Here's exactly how to get licensed in 2026.
Arizona Doesn't Have One HVAC License — It Has Three
The Arizona Registrar of Contractors (AZ ROC) issues separate HVAC licenses based on the scope of work:
- R-39 — Residential Air Conditioning & Refrigeration only. For contractors working exclusively on homes and residential buildings.
- C-39 — Commercial Air Conditioning & Refrigeration. Required for commercial, industrial, and mixed-use work on HVAC systems and ductwork.
- CR-39 — Combination residential + commercial. The most flexible license and the most common for contractors who want to serve all markets.
Most Phoenix-area contractors pursue the CR-39 because Phoenix commercial development is robust and having both classifications opens more bid opportunities.
The Complete Step-by-Step Process
You need at least 4 years of hands-on HVAC field experience to qualify. Technical school or trade school training can substitute for up to 2 of those 4 years. Document your work history — you'll need employer references and dates.
Before you can apply, you must pass Arizona's Statutes & Rules Exam through Gmetrix. The SRE covers Arizona contractor law, the ROC's rules, and business regulations. Exam fee: $61. Schedule at roc.az.gov.
The R-39/C-39/CR-39 trade exam is administered by PSI Exams at five testing centers in Arizona (Flagstaff, Glendale, Phoenix, Tempe, Tucson). The exam covers refrigeration systems, HVAC installation, load calculations, and safety. Fee: $66 (one exam) or $116 (Business Management + Trade exam bundle — recommended).
Arizona ROC requires a fingerprint-based background check for all new applicants. This is handled through the ROC during the application process. Budget 2–4 weeks for processing.
Arizona requires contractors to post a surety bond. The bond amount is based on your projected annual revenue — for most new HVAC contractors, this is typically $2,500–$7,500/year. Shop multiple surety bond providers for the best rate.
Submit your complete application at roc.az.gov. The license fee for C-39 (and CR-39) is $580 for a 2-year license — all ROC licenses run on a 2-year cycle. R-39 (residential only) may have a different fee tier. Verify current fees at roc.az.gov/licensing-fees.
Federal law (Clean Air Act) requires anyone purchasing or handling refrigerants to be EPA 608 certified. This is separate from the ROC license and is handled through approved private testing organizations. Cost: $20–$50. You need this before touching refrigerants on any job.
HVAC contractors in Arizona are subject to Transaction Privilege Tax on contracting revenue. Register at AZTaxes.gov. If you work in Phoenix, you'll also register for Phoenix's city TPT separately. This applies to the contracting classification — not sales tax on parts alone.

Common Mistakes That Delay Your License
Applying before passing both exams. You must pass the SRE and the trade exam before submitting your ROC application. Applying early just wastes the application fee.
Underestimating experience documentation. ROC reviewers look carefully at work history. Gaps or vague employer references get flagged. Document every employer, date, and role clearly.
Skipping the EPA 608. The ROC doesn't require it, but you need it to legally purchase refrigerants and do most residential and commercial HVAC work. Get it before you start taking jobs.
Forgetting TPT registration. Many new contractors start taking jobs and don't register for TPT until the Department of Revenue catches up with them. Register before your first job.
