Licensing Steps

Arizona contractor licensing is handled by the Arizona Registrar of Contractors. Candidates should begin by identifying the correct license classification for the work they plan to perform. For air conditioning and refrigeration work that includes both residential and commercial scope, the CR-39 residential/commercial path is the classification connected to this package.

The person responsible for satisfying the examination requirement is the qualifying party. The qualifying party is the individual who demonstrates the trade knowledge required for the license classification. Arizona contractor applicants may also need to complete the Arizona Statutes and Rules Exam, commonly called the SRE, in addition to the trade examination.

The Arizona Statutes and Rules Exam is a computer-based course and exam maintained by the Arizona Registrar of Contractors. It covers Arizona contractor statutes and rules that apply to licensing, business conduct, compliance, and contractor responsibilities. New license applicants who have not recently served as a qualifying party on another Arizona contractor license may be required to complete the SRE.

For the trade examination, candidates follow PSI scheduling procedures and select the correct Arizona air conditioning and refrigeration examination. Candidates should confirm that the examination selected matches the license classification they are pursuing. PSI offers computer-based contractor trade examinations and provides instructions for registration, scheduling, identification, test center rules, and remote proctoring where available.

After completing the required examination steps, applicants submit the completed license application and required documentation to the Arizona Registrar of Contractors. Application processing may involve qualifying party information, business entity information, bonding, required fees, background information, and other items required for the selected license classification.

Arizona licensing applications must be submitted within the applicable time period after passing the required examination. Candidates should keep the original score report and all examination records because those materials may be required during the licensing application process.

State Requirements

The Arizona Registrar of Contractors licenses and regulates residential and commercial contractors in Arizona. The CR-39 classification is the residential/commercial air conditioning and refrigeration classification path. It is designed for contractors whose work includes air conditioning, refrigeration, evaporative cooling, heating, ventilation, and related mechanical systems within the scope of the classification.

The CR-39 scope includes installation, alteration, and repair of refrigeration and evaporative cooling systems. It also includes heating systems, ventilation systems, duct work, air filtering devices, water treatment devices, control piping, thermal and acoustical insulation, vibration isolation materials, liquid fuel piping and tanks, and water and gas piping from the service connection to the equipment served.

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

Contractors who work with refrigerants should also understand that refrigerant handling is subject to federal requirements separate from state contractor licensing. The CR-39 trade exam package supports Arizona contractor exam preparation, while refrigerant certification and environmental compliance responsibilities must be handled according to the applicable federal rules for refrigerant work.

Test Information and Study Materials

The Arizona CR-39 exam requires candidates to connect field experience with code-based reference skills. The exam is open book, but 80 questions in 210 minutes still requires steady pacing. Candidates should be prepared to move efficiently through the International Mechanical Code, International Fuel Gas Code, and OSHA construction safety standards.

Start with the International Mechanical Code, 2018. This book supports many of the mechanical system topics connected to air conditioning and refrigeration work. Candidates should review equipment installation, ventilation air, exhaust systems, duct systems, combustion air, mechanical system clearances, appliance installation, refrigeration-related provisions, and system safety requirements.

The International Fuel Gas Code, 2018 should be studied carefully for gas piping and gas-fired equipment topics. Candidates should be familiar with fuel gas definitions, pipe sizing concepts, gas pressure, shutoff valves, sediment traps, appliance connections, combustion air, venting, chimneys, connectors, appliance installation, and inspection requirements. Gas code questions often require close reading because one word or exception can change the correct answer.

The OSHA construction safety reference is important for safety-related exam questions. Candidates should review personal protective equipment, ladders, scaffolds, fall hazards, excavation hazards, electrical safety, hand and power tools, material handling, housekeeping, hazard communication, and general safe work practices. HVAC and refrigeration contractors work around equipment, electrical systems, roof access, confined areas, refrigerant lines, gas piping, and mechanical rooms, so safety knowledge is an important part of exam preparation.

Because the exam is open book, candidates should prepare the references before the test appointment. Permanent tabs can help locate important chapters, tables, and subject areas. Highlighting and annotations should be completed before exam day and should be limited to useful navigation and study notes. Over-marking a book can make it harder to use during a timed exam, so candidates should focus on important sections and clear organization.

Practice should include timed questions. With 210 minutes for 80 questions, candidates have a little over two and a half minutes per question. Some questions can be answered quickly from trade knowledge, while others require looking up code language. A good strategy is to answer familiar questions first, mark difficult questions, and return to them after building momentum.

Candidates should also practice deciding which reference to use. Safety questions generally belong in OSHA. Fuel gas piping, gas appliances, combustion air, and venting questions often belong in the International Fuel Gas Code. Mechanical equipment, ventilation, ducts, exhaust, and mechanical installation questions often belong in the International Mechanical Code. Learning that decision-making process can save valuable time on the exam.

When reviewing practice questions, candidates should avoid memorizing only the answer. The stronger method is to locate the answer in the reference, read the related section, and understand why the other choices are incorrect. This helps build the kind of code navigation skill needed when exam questions are worded differently from study questions.
