Arizona HVAC Contractor License Requirements (2026)

The Arizona Registrar of Contractors (AZ ROC) licenses air-conditioning and refrigeration contracting businesses statewide under A.R.S. Title 32, Chapter 10. C-39 covers commercial Air Conditioning and Refrigeration, R-39R covers residential Air Conditioning and Refrigeration, and CR-39 combines those scopes. Each applicant needs a regularly employed qualifying party who meets the classification requirements. Federal refrigerant-handling rules are separate from the AZ ROC contractor-license application.

Regulatory Body

Under Arizona Revised Statutes Title 32 Chapter 10; Arizona Administrative Code Title 4 Chapter 9, Arizona Registrar of Contractors (AZ ROC) is the body that issues this license and enforces compliance with it. AZ ROC licenses residential, commercial, and dual contractors statewide, administers the Residential Contractors Recovery Fund, and conducts complaint investigations and disciplinary proceedings.

Eligibility Requirements

Applicants must be at least 18 years old. Applicants must provide a Social Security Number. No Arizona residency requirement.

Good moral character

AZ ROC conducts a fitness review on every qualifying party. Felony convictions and prior license revocations are reviewed individually.

Background investigation

Mandatory criminal history disclosure on the application.

Experience and Education

The applicant must document and verify at least four years of hands-on and/or managerial air-conditioning and refrigeration experience. Keep payroll, tax, project, or supervisor records to support the claim, as the board can request proof for any period within its lookback window.

Accepted proof of experience or eligibility

AZ ROC Statement of Experience in the applicable license application, completed by the qualifying party
Employment and tax records kept available if AZ ROC requests supporting documentation
Official transcripts or training records when claiming education or training credit allowed for the classification

Education substitution

Review the current AZ ROC License Classification Requirements for the selected classification; C-39, R-39R, and CR-39 each require four years of hands-on and/or managerial experience.

Exam Requirements

Testing provider or authority: GMetrix for the Arizona Statutes and Rules course/exam; PSI Exams Online for the trade examination. The following examination requirements cover the pathways described in this guide; follow each part's classification, waiver, and local-scope conditions. Unpublished format details do not remove an examination requirement:

Arizona Statutes and Rules Training Course and Examination (SRE) — question count: confirm with the authority, timing: confirm with the authority, passing score 70%
Trade examination for C-39, R-39R, or CR-39, unless waived — question count: confirm with the authority, timing: confirm with the authority, passing score 70%

Examination fee: The online SRE course and exam is $61 paid directly to GMetrix. The trade-specific PSI exam is $66. Confirm the current provider fee before scheduling.

Retake policy: Submit passing SRE and trade-exam results with the application, unless the trade requirement is waived. Check the provider’s current retake rules and fee before scheduling.

Insurance and Bonds

A contractor license surety bond of $2,500, on the AZ ROC's prescribed form, is a precondition to issuance.

General liability

AZ ROC does not impose a state-level general liability minimum. Most commercial owners contractually require $1,000,000/$2,000,000.

Workers' compensation

Workers' compensation insurance is mandatory in Arizona under A.R.S. §23-961 for any business with one or more employees.

Additional financial requirements

Commercial specialty bonds begin at $2,500 at $150,000 or less annual Arizona volume; residential specialty bonds begin at $4,250 below $375,000; a CR-39 dual bond combines the applicable commercial and residential amounts. Residential and dual licenses generally pay the Residential Contractors’ Recovery Fund assessment or may post the alternative $200,000 surety/cash bond.

Fee Schedule

Fee	Amount
Application	$80

Initial license	$270
Renewal (every 2 years)	$540

Reciprocity

The NASCLA Accredited Examination is not accepted by Arizona for this classification.

Reciprocal State	Accepted Exam	Conditions
No formal bilateral reciprocity agreements identified.

Arizona does not have direct reciprocity with other states. An out-of-state qualifying party may request a trade-exam and experience waiver when they held a comparable out-of-state license within the prior five years and obtained it by trade examination. The SRE remains required.

HVAC Licensing in Neighboring States

Contractors working near a state line, or weighing where to qualify first, should compare Arizona's requirements against the bordering jurisdictions before committing to an application:

California HVAC License Requirements — California Class C-20 — Warm-Air Heating, Ventilating and Air-Conditioning Contractor
Colorado HVAC License Requirements — Colorado HVAC — local mechanical contractor licensing; EPA Section 608 where applicable
Nevada HVAC License Requirements — Nevada C-21 Refrigeration and Air-Conditioning Contractor
New Mexico HVAC License Requirements — New Mexico MM-3 HVAC Contractor and Mechanical Journeyman Certificates
Utah HVAC License Requirements — Utah H100 HVAC Contractor License

Step-by-Step Application Roadmap

Choose the classification. C-39 is commercial Air Conditioning and Refrigeration, R-39R is residential Air Conditioning and Refrigeration, and CR-39 combines both scopes. Review AZ ROC’s current scope description before applying.
Document four years of qualifying experience. The qualifying party must meet the C-39, R-39R, or CR-39 requirement of four years of hands-on and/or managerial experience.
Complete the required examinations. Complete the online, open-book Arizona Statutes and Rules course/exam through GMetrix and the required trade exam through PSI, unless a trade waiver is approved.
Submit the AZ ROC application. File the application with qualifying-party information and the required SRE and trade-exam results, or a completed trade-waiver request when eligible.
Post the contractor license bond and insurance. Bond amount scales with annual gross volume. Workers compensation is required for businesses with employees.
Pay fees and receive the AZ ROC license. Pay the license fee and, for applicable residential or dual classifications, the Recovery Fund assessment or alternative bond. Arizona contractor licenses renew every two years.

Application Checklist

The most critical documents or confirmations the applicant should have in hand before filing with AZ ROC:

AZ ROC application with the classification-specific fee and qualifying party designation
AZ ROC Statement of Experience showing four years for C-39, R-39R, or CR-39
GMetrix Arizona Statutes and Rules course/exam pass result at 70%+
PSI HVAC trade-exam pass result at 70%+ or an approved waiver
Contractor license bond at the volume-appropriate amount
Workers compensation coverage certificate (any business with one or more employees)

Common Filing Mistakes

Based on the board's own instructions and the sources cited here, the problems below are what most often stall a Arizona HVAC application.

Looking for a journeyman card

Arizona has no individual HVAC technician credential. Individuals work under a licensed contracting business.

Skipping EPA 608

EPA Section 608 is a separate federal rule for technicians performing covered refrigerant work; it is not an AZ ROC C-39 application document.

Choosing the wrong classification

R-39R is residential, C-39 is commercial, and CR-39 is the dual classification. Do not rely on the obsolete L-39 label.

Underestimating the bond amount

The bond scales with annual gross volume. Contractors who exceed their bonded volume must immediately upgrade.

Skipping workers compensation

Arizona requires workers compensation for any business with one or more employees.

Frequently Asked Questions

Does Arizona issue journeyman HVAC technician licenses?

AZ ROC licenses HVAC contracting businesses, not individual technicians. C-39 is commercial, R-39R is residential, and CR-39 is dual. Check local jurisdictions and applicable federal rules for worker-specific requirements.

What is the difference between C-39, R-39R, and CR-39?

C-39 covers commercial Air Conditioning and Refrigeration; R-39R covers residential Air Conditioning and Refrigeration; CR-39 combines the C-39 and R-39R scopes.

Is EPA Section 608 required?

EPA Section 608 is a separate federal technician rule, not an AZ ROC contractor-license application requirement. Confirm the federal requirement for the proposed refrigerant-handling task.

Does Arizona accept the NASCLA exam for HVAC contractors?

AZ ROC’s current application guidance identifies NASCLA alternatives for specified general-building and electrical classifications, not C-39, R-39R, or CR-39. HVAC applicants should complete the AZ ROC-required trade exam unless an individual waiver is approved.

How often does the Arizona HVAC contractor license renew?

Every two years. There is no continuing education requirement, but the bond and workers compensation must remain in force.
