Licensing Steps

Arizona contractor licensing is handled through the Arizona Registrar of Contractors. Contractors pursuing the R-39 Air Conditioning and Refrigeration, Including Solar Residential classification should follow the state licensing process for the proper classification, business structure, and qualifying party. Because R-39 is a residential classification that includes solar, applicants should make sure this license path matches the residential HVAC/R and solar-related work they plan to perform.

A practical licensing path begins with choosing the correct classification. The applicant then identifies the qualifying party, who is the person connected to the trade knowledge and experience for the license. From there, the applicant follows the Arizona ROC application process, gathers required business information, completes required forms, and satisfies the requirements connected to the license.

Exam preparation should begin early because the R-39 exam involves several technical areas. Students need time to review mechanical code, fuel gas code, plumbing code, refrigeration, air conditioning systems, heating equipment, boilers, duct sizing, solar water heating, solar pool heating, and OSHA safety. Students who study consistently have more time to become comfortable with the books, review important trade concepts, and build a repeatable test-taking approach. This Ultimate package supports that process with 1 year of course access, rental reference books, and Application Service.

Passing the exam and receiving license approval are separate parts of the licensing process. This product supports preparation for the Arizona Air Conditioning and Refrigeration, Including Solar Residential Contractor (R-39) exam and includes Application Service to help students stay organized while working through the licensing path.
