Licensing Steps

Arizona contractor licensing is handled through the Arizona Registrar of Contractors. Candidates should begin by selecting the correct license classification for the work they plan to perform. The C-79 classification applies to commercial air conditioning and refrigeration including solar contractor work within the allowed Arizona license scope.

After selecting the correct classification, candidates should review the examination requirements connected to the license. The C-79 trade exam preparation path is one part of the licensing process. Contractor applicants may also need to complete the Arizona business management or statutes and rules requirement, application requirements, qualifying party requirements, bonding requirements, experience requirements, and other items required by the Arizona Registrar of Contractors.

Exam preparation and application preparation should be treated as separate tasks. Exam preparation focuses on HVAC and refrigeration trade knowledge, solar-related system concepts, open-book reference navigation, OSHA safety, mechanical code, fuel gas code, plumbing code, refrigeration, air conditioning, heating, controls, motors, ventilation, fuel piping, water piping, boilers, testing, balancing, sizing, estimating, and inspection topics. Application preparation focuses on state forms, business information, qualifying party documentation, bond requirements, fees, and licensing submission requirements.

This highlighted and tabbed books package supports the exam preparation side of the process. It gives candidates the listed exam-room references in an organized format so they can study directly from the books they plan to use. Candidates should use the books consistently before exam day so the tabs, highlighting, chapter layout, and code organization become familiar.

State Requirements

The Arizona Registrar of Contractors issues licenses by classification. Commercial classifications apply to commercial work, residential classifications apply to residential work, and dual classifications may apply when a contractor qualifies for both residential and commercial work. The C-79 classification is the commercial air conditioning and refrigeration including solar contractor classification.

The air conditioning and refrigeration classification is connected to installation, alteration, and repair of air conditioning, refrigeration, ventilation, warm air heating, evaporative cooling, duct systems, and related mechanical systems within the allowed Arizona license scope. Because this classification includes solar, candidates should also prepare for solar heating system concepts and coordination with mechanical and plumbing systems.

Commercial HVAC and refrigeration contractors should understand the limits of their classification and work within the scope issued by the state. Work outside the classification may require another properly licensed contractor. HVAC, refrigeration, and solar-related mechanical work may involve coordination with mechanical systems, fuel gas systems, plumbing systems, electrical systems, building provisions, ventilation systems, safety requirements, and jobsite conditions.

Passing the trade exam is not the same as receiving a license. Applicants are responsible for meeting the full Arizona licensing requirements that apply to the classification, qualifying party, business entity, bond, application, and related state requirements. This package supports preparation by providing the listed highlighted and tabbed books allowed into the C-79 exam room.
