Arizona HVAC Contractor License Requirements (2026)

The Arizona Registrar of Contractors (AZ ROC) licenses air conditioning and refrigeration contractors statewide under A.R.S. Title 32 Chapter 10. Arizona licenses HVAC contracting businesses at the C-39 (Commercial Air Conditioning and Refrigeration), CR-39 (Residential Air Conditioning and Refrigeration), or L-39 (Dual) classifications. Each business must designate a qualifying party with four years of trade experience who passes the PSI examinations. Federal EPA Section 608 certification is also required for any work involving refrigerants.

Background investigation

Mandatory criminal history disclosure on the application.

Required Experience and Education

The applicant must document and verify at least four years of practical air conditioning, refrigeration, or HVAC experience within the prior ten years at the journeyman, foreman, supervisor, or contractor level. Keep payroll, tax, project, or supervisor records to support the claim, as the board can request proof for any period within its lookback window.

Notarized affidavits from prior supervising HVAC contractors

Education substitution

Up to two of the four years may be satisfied by accredited HVAC apprenticeship and trade school coursework on a sliding scale set by AZ ROC rule.

Examination Requirements

The licensing examination is delivered by PSI Services LLC (under contract to AZ ROC). All of the following parts must be cleared prior to issuance:

Examination fee: $83 per exam part paid to PSI on the day of testing.

Retake policy: Failed parts may be re-taken individually by paying a new $83 fee. Each application remains valid for one year.

A contractor license surety bond of $4,250, on the AZ ROC's prescribed form, is a precondition to issuance.

Reciprocity and License Transfer

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

Reciprocal State	Accepted Exam	Conditions
California	Trade exam waived	Bilateral AZ ROC–CSLB reciprocity for active HVAC contractors in good standing for at least five years.
Nevada	Trade exam waived	Bilateral AZ ROC–Nevada State Contractors Board reciprocity.
Utah	Trade exam waived	Bilateral AZ ROC–Utah DOPL reciprocity.

Arizona licenses HVAC contracting businesses, not individual technicians. Out-of-state journeymen cannot reciprocate as individuals — they must qualify a business.

Application Process, Step by Step

Choose the classification. C-39 Commercial Air Conditioning and Refrigeration, CR-39 Residential, or L-39 Dual.
Document four years of qualifying experience. Prepare the AZ ROC Statement of Experience form covering the prior ten years at the journeyman level or above.
Obtain EPA Section 608 certification. Federal refrigerant handling certification is required for any work involving refrigerants.
Submit the AZ ROC application. File with the application fee, qualifying party designation, and proof of experience.
Pass both PSI examinations at 70%. Score 70% or better on the Arizona Statutes and Rules exam and the HVAC trade exam covering the IMC and IFGC.
Post the contractor license bond and insurance. Bond amount scales with annual gross volume. Workers compensation required for any business with one or more employees.
Receive the AZ ROC license. AZ ROC issues the license after the exam is passed and the bond is filed. The license must be renewed every two years.

Frequent Application Errors

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 federal and required before touching any refrigerant. AZ ROC will reject incomplete applications.

Choosing the wrong classification

A CR-39 residential HVAC contractor cannot bid commercial work. L-39 is required for dual scope.

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.
