Arizona contractor applicants may also need to complete the Arizona Statutes and Rules Exam, commonly known as the SRE. The SRE covers Arizona contractor statutes and rules related to licensing, business conduct, compliance, and contractor responsibilities. New applicants should review the Arizona Registrar of Contractors requirements for their qualifying party status and selected license classification.

For the trade examination, candidates follow PSI scheduling procedures and select the correct Arizona air conditioning and refrigeration, including solar, residential/commercial examination. PSI provides instructions for registration, scheduling, identification, cancellation, test center rules, remote proctoring options where available, and exam-day conduct.

After completing the required examination steps, applicants submit the license application and required documents to the Arizona Registrar of Contractors. Application processing may include qualifying party information, business entity information, bonding, required fees, background information, and other documentation required for the selected residential/commercial contractor classification.

Candidates should keep their original score report and related examination records. Licensing applications must be submitted within the applicable time period after passing the required examination, and exam records may be needed during the application process.

State Requirements

The Arizona Registrar of Contractors licenses and regulates residential and commercial contractors in Arizona. Arizona issues separate licenses for commercial work, residential work, and dual licenses that cover both commercial and residential work for a particular trade or construction field. The CR-79 classification is the dual residential/commercial classification for air conditioning and refrigeration, including solar.

The CR-79 path combines the residential R-39 and commercial C-79 scopes. This allows candidates to prepare for a broader classification that includes residential comfort air conditioning and commercial HVAC/R work within the limits of the classification. Candidates should make sure the classification they choose matches the exact work their business intends to perform.

The licensing process can include trade examination requirements, the Arizona Statutes and Rules Exam, qualifying party requirements, business documentation, bonding, application forms, fees, and compliance with Arizona contractor licensing rules. Applicants should review the current Arizona Registrar of Contractors requirements before applying.

Contractors who handle refrigerants should also understand that refrigerant work is subject to federal requirements separate from state contractor licensing. This exam package supports Arizona contractor exam preparation, while refrigerant certification and environmental compliance responsibilities must be handled according to applicable federal refrigerant rules.

Test Information and Study Materials

The Arizona CR-79 exam requires candidates to connect residential and commercial HVAC/R field knowledge with code-based reference skills. Because the exam is open book, candidates should study directly from the references they plan to bring into the exam room. The goal is to understand the trade topics and know where important information is located.

Start with the International Mechanical Code, 2018. This book supports many of the mechanical system topics connected to air conditioning and refrigeration work, including equipment installation, ventilation, exhaust, duct systems, combustion air, refrigeration-related requirements, clearances, and system safety. Candidates should become familiar with the table of contents, definitions, chapter layout, index, and commonly used tables.

The International Fuel Gas Code, 2018 should be studied for gas-fired equipment, fuel gas piping, appliance installation, venting, combustion air, chimneys, connectors, shutoff valves, sediment traps, and inspection requirements. Fuel gas questions often require careful reading because equipment type, location, pressure, and venting method can affect the correct answer.

The International Plumbing Code, 2018 supports questions involving water piping systems, equipment connections, plumbing coordination, and code provisions related to mechanical work. HVAC/R contractors may encounter questions where water piping, condensate handling, drainage coordination, or equipment service connections matter.

The OSHA reference supports safety-related questions. Candidates should review personal protective equipment, ladders, scaffolds, fall protection, excavation hazards, electrical safety, hand and power tools, material handling, hazard communication, housekeeping, and safe work practices. HVAC/R contractors often work around roof-mounted units, mechanical rooms, refrigerant piping, electrical equipment, gas piping, ladders, cranes, and confined areas, so safety knowledge is an important part of preparation.

Candidates should prepare the books before exam day. Permanent tabs can help identify important chapters, definitions, tables, and subject areas. Highlighting and annotations should be completed before the examination session. Over-marking can make a book harder to use, so candidates should focus on clear organization and the areas most likely to be needed during the test.

Timed practice is important. With 210 minutes for 80 questions on the main exam, candidates have a little more than two and a half minutes per question. Some questions may be answered from trade knowledge, while others require code lookup. A good strategy is to answer familiar questions first, mark difficult questions, and return to them after making progress.

Candidates should also practice choosing the correct reference. OSHA safety questions generally belong in 29 CFR Part 1926. Gas piping, combustion air, venting, and fuel gas appliance questions often belong in the International Fuel Gas Code. Mechanical equipment, ventilation, ducts, exhaust, and refrigeration-related questions often belong in the International Mechanical Code. Water piping and plumbing coordination questions often belong in the International Plumbing Code.
