Planning to run HVAC jobs in Arizona? You'll need a license from the Arizona Registrar of Contractors (ROC), and the first decision is which classification fits your work: R-39 (residential), C-39 (commercial), or CR-39 (both). This guide covers the four-year experience rule, the two exams, the surety bond, and the exact ROC fees for each classification.
Do You Need an HVAC License in Arizona?
Yes, any individual or business performing HVAC work for compensation in Arizona must hold a valid contractor's license issued by the Arizona Registrar of Contractors (ROC) — the ROC defines "contractor" broadly, so even smaller repair jobs typically require one. It applies to the installation, alteration, repair, and service of any heating, ventilation, and air conditioning systems.
Understanding Arizona HVAC License Classifications
The Arizona Registrar of Contractors issues three primary classifications for HVAC work, each defining the scope of projects you can legally perform — your choice between R-39 (residential), C-39 (commercial), or CR-39 (both) depends on the work you plan to do.
R-39 Residential Air Conditioning and Refrigeration (Including Solar)
The R-39 license authorizes comfort air conditioning, refrigeration, evaporative cooling, ventilating, and heating work — with or without solar equipment — on residential structures, along with related controls and limited new-circuit additions to existing panels and subpanels.
C-39 Commercial Air Conditioning and Refrigeration
The C-39 license authorizes the installation, alteration, and repair of refrigeration, evaporative cooling, heating, and ventilation systems — along with related controls, ductwork, certain piping, and limited new-circuit additions to existing panels — on commercial (non-residential) projects.
CR-39 Dual Air Conditioning and Refrigeration
The CR-39 is a dual license that combines the scopes of the commercial C-39 and residential R-39R classifications, allowing HVAC and refrigeration work on both residential and commercial projects.
What are the Eligibility Requirements for an Arizona HVAC License?
To be eligible for an Arizona HVAC license, applicants must meet specific experience, financial responsibility, and background check requirements set by the Arizona Registrar of Contractors.
Experience Requirements
Applicants for an HVAC contractor license in Arizona must have at least four years of verifiable, practical experience in the trade, at a journeyman level or higher, documented through a qualifying party who can attest to your work history. Each of the R-39, C-39, and CR-39 classifications requires four years of experience plus the Statutes & Rules and trade exams. Keep detailed work logs and supervisor contacts from the start — thorough documentation clears the ROC's experience verification without delays.
Financial Responsibility and Bonding
All Arizona HVAC contractors must demonstrate financial responsibility by securing a surety bond, in an amount based on your license type and gross annual work volume. For residential specialty contractors, the bond is $4,250 (under $375,000 in gross volume) or $7,500 ($375,000 or more). For commercial specialty contractors, it ranges from $2,500 to $50,000 by gross volume. Dual (CR) bond amounts are calculated by combining the residential and commercial amounts.
Background Check Requirements
The ROC checklist requires background checks for all persons listed on the license application, including the qualifying party and business owners. Confirm the current fingerprinting and submission details on the ROC checklist.
Business Registration
Your business entity must be in good standing and registered with the Arizona Corporation Commission before a license can be issued. This applies whether you operate as a sole proprietorship, partnership, LLC, or corporation.
The Arizona HVAC Licensing Application Process: Step-by-Step
The path to licensure involves submitting a complete application, passing two exams, and providing proof of financial responsibility.
Step 1: Prepare Your Application
The first step is to gather all required documentation for the application: detailed experience affidavits for your qualifying party, financial statements, and business registration documents. Review the ROC's official checklist closely — incomplete applications are the most common cause of delay.
Step 2: Submit Your Application
You can submit your application through the ROC online customer portal, or download the application form and submit it by mail.
Step 3: Schedule and Pass Required Exams
All applicants must pass two exams: the Arizona Statutes and Rules Exam (SRE), administered through GMetrix, which covers state business-management and construction laws; and the trade-specific exam for your classification (R-39, C-39, or CR-39), administered through PSI — unless you qualify for a waiver. Confirm the current passing score with the ROC. An exam-prep course is worth considering for the Statutes and Rules exam, which covers state-specific regulations unfamiliar even to experienced contractors.
Step 4: Obtain Surety Bond and Insurance
After passing the exams, you must acquire a surety bond in the amount determined by the ROC for your classification and gross volume, then submit proof to the ROC.
Step 5: Final Review and License Issuance
Once all exam results, background checks, and bond/insurance documents are received and approved, the ROC will conduct a final review and issue your Arizona contractor's license.
How Much Does an HVAC License Cost in Arizona?
ROC fees depend on your classification. The figures below are the ROC's application fee, license fee, and (for residential and dual licenses) the recovery-fund assessment; the totals do not include exam fees.
| Classification | Application | License | Recovery fund | Total |
|---|---|---|---|---|
| Specialty Residential (R-39) | $80 | $270 | $370 | $720 |
| Specialty Commercial (C-39) | $100 | $480 | — | $580 |
| Specialty Dual (CR-39) | $100 | $380 | $370 | $850 |
Exam fees (separate): the Statutes & Rules Exam is $61 (paid to GMetrix) and the trade exam is $66 (paid to PSI). On top of these, budget for your surety-bond premium (a percentage of the required bond), background-check costs, and any Arizona Corporation Commission business-registration fee.
EPA Section 608 Certification for HVAC Technicians
All technicians who maintain, service, repair, or dispose of equipment that could release refrigerants into the atmosphere must obtain EPA Section 608 certification. This is a mandatory federal requirement enforced by the U.S. Environmental Protection Agency and is separate from Arizona's state-level contractor licensing. There are four types of certification (Type I, II, III, and Universal), and you must hold the appropriate type for the equipment you service.
Arizona HVAC License Renewal
Arizona contractor licenses are issued for a two-year term and must be renewed to remain active; the ROC fee schedule lists the renewal fees by classification. Failure to renew on time can result in penalties and suspension of your license. The ROC does not list a continuing-education requirement for these HVAC classifications — confirm the current renewal requirements and deadlines on the ROC's fee and renewal pages.
Does Arizona Offer HVAC License Reciprocity?
Arizona's ROC checklist references in-state and out-of-state exam-waiver options for qualifying applicants, rather than blanket reciprocity. Whether any of your exams can be waived depends on your background and the ROC's current waiver rules.
Penalties for Unlicensed HVAC Contracting in Arizona
Performing HVAC work in Arizona without the required ROC license carries serious consequences, and unlicensed work can also make it difficult to pull permits or pass inspections — putting both the contractor and the property owner at risk. Confirm the specific penalties with the ROC.
