Licensing Steps

Arizona contractor licensing is handled through the Arizona Registrar of Contractors. A candidate pursuing the Arizona Air Conditioning and Refrigeration Residential Contractor (R-39R) license should begin by confirming that the residential air conditioning and refrigeration classification matches the work the business intends to perform.

After identifying the correct classification, the candidate should review the required examination path. Arizona contractor licensing may include a trade examination, statutes and rules requirements, qualifying party requirements, experience requirements, bonding, business entity information, and application documentation. This exam book package supports the technical study portion of that licensing process.

The qualifying party is responsible for demonstrating the knowledge and experience required for the license classification. Candidates should prepare for the trade examination using the approved references and supporting study materials included in this package. After preparation, the candidate can schedule the examination through the proper testing process and complete the exam according to current testing procedures.

Once examination requirements are satisfied, the applicant continues through the Arizona contractor license application process. This may include submitting the correct application, naming the qualifying party, meeting experience requirements, obtaining the required bond, and satisfying other state licensing requirements that apply to the classification and business structure.

This book package does not replace the state license application. It supports preparation for the trade exam by giving candidates the references and study materials needed to review the major HVAC, refrigeration, mechanical, fuel gas, duct, boiler, and OSHA safety topics connected to the Arizona R-39R residential contractor exam.
