The goal is to help you prepare with a clear study structure instead of trying to piece together exam materials on your own. The package supports candidates who want to study the Arizona CR-39 exam references, build confidence with open-book navigation, and stay focused on the steps needed to move from exam preparation into the contractor licensing process.

Exam Details

The Arizona CR-39 Air Conditioning and Refrigeration Residential / Commercial Contractor exam is part of the Arizona contractor trade examination process administered through PSI for the Arizona Registrar of Contractors. Candidates preparing for this exam should expect a trade-focused assessment that measures knowledge related to air conditioning, refrigeration, mechanical systems, fuel gas systems, safety, installation practices, system components, troubleshooting concepts, and code-based requirements tied to the HVAC trade.

This package focuses on the study materials listed for this Arizona CR-39 preparation path. The books and tools support several major areas of exam preparation. The OSHA construction safety reference helps candidates review jobsite safety practices and construction safety requirements. The International Mechanical Code supports preparation for HVAC equipment, ventilation, exhaust systems, duct systems, combustion air, and mechanical system installation rules. The International Fuel Gas Code supports fuel gas piping, appliance connections, venting, combustion air, pressure testing, and fuel gas safety topics.

Modern Refrigeration and Air Conditioning provides broad trade knowledge for refrigeration cycles, air conditioning systems, heating systems, controls, troubleshooting, components, and service practices. Low Pressure Boilers supports review of boiler principles and related heating-system knowledge. Manual D helps candidates study residential duct design principles, sizing concepts, air distribution, and duct system layout. The Ductulator supports airflow and duct-sizing practice, which is especially useful for candidates who need to strengthen speed and confidence with air distribution calculations and layout concepts.

Exam preparation should include both content review and reference navigation. For open-book contractor exams, many candidates struggle not because they have no books, but because they have not practiced using those books under time pressure. A strong study plan should include reading key sections, reviewing tables and indexes, becoming familiar with chapter organization, and practicing how to locate answers quickly.

Open Book Test

The Arizona CR-39 Air Conditioning and Refrigeration Residential / Commercial Contractor exam is an open-book exam, meaning approved reference materials may be used in the testing center. Open-book does not mean easy. The advantage comes from knowing how to use the references quickly, accurately, and calmly while the clock is running.

For this preparation package, the core exam-room reference focus includes the Code of Federal Regulations – 29 CFR Part 1926 (OSHA), the 2018 International Fuel Gas Code, and the 2018 International Mechanical Code. These references support code-based and safety-based questions that may require candidates to locate specific requirements rather than rely only on memory.

The additional study materials in this package help strengthen trade understanding and practical preparation. Modern Refrigeration and Air Conditioning, Low Pressure Boilers, Manual D, and the Ductulator are valuable study resources for building knowledge around systems, design, calculations, operating principles, and field application. Candidates should use these materials to develop a stronger understanding of the HVAC and refrigeration concepts that support exam performance and contractor readiness.

Because open-book exams reward preparation and speed, candidates should avoid waiting until test day to open the references for the first time. A good study routine includes learning the table of contents, index, chapter layout, definitions, tables, illustrations, and code organization. The more familiar you are with the materials before exam day, the easier it is to work through questions with confidence.

Licensing Steps

The Arizona CR-39 licensing path generally involves preparing for the applicable contractor examinations, completing the examination process through PSI, and submitting the required contractor license application materials to the Arizona Registrar of Contractors. Candidates should follow the current Arizona Registrar of Contractors and PSI instructions for registration, testing, application submission, and supporting documentation.

A practical licensing plan begins with choosing the correct classification. The CR-39 classification is intended for candidates pursuing the dual residential and commercial air conditioning and refrigeration contractor classification. Candidates should make sure the classification matches the type of work the business intends to perform.

After confirming the classification, candidates should prepare for the required trade exam and any additional required contractor examination. Preparation should include a study schedule, review of the listed references, practice with open-book navigation, and review of the topics connected to HVAC systems, refrigeration, safety, fuel gas, mechanical code requirements, duct design, and related trade knowledge.

Once the exam preparation stage is complete, candidates register for the required examinations through the approved testing process. After passing the required examinations, the licensing process continues with the Arizona Registrar of Contractors application. Application materials may include business information, qualifying party information, financial or bonding requirements, background-related items, and other state-required documents depending on the applicant’s structure and license classification.

This package includes Application Service support to help candidates stay organized through the application stage. Application Service is designed to support the licensing paperwork process and help reduce confusion as candidates move from exam preparation into submission readiness.

State Requirements

Arizona contractor licensing is regulated by the Arizona Registrar of Contractors. The CR-39 classification allows the scopes of work permitted by the commercial C-39 Air Conditioning and Refrigeration classification and the residential R-39R Air Conditioning and Refrigeration classification. This makes it a dual classification for contractors preparing to serve both residential and commercial customers within the air conditioning and refrigeration trade.

Candidates should be prepared to meet Arizona’s contractor licensing requirements before performing regulated contracting work. The state licensing process is separate from simply buying exam books or taking a preparation course. Exam preparation helps candidates get ready for the testing portion, while the license application process addresses the state’s contractor licensing requirements.

For Arizona HVAC professionals, the CR-39 path may be appropriate for businesses involved in air conditioning, refrigeration, heating, ventilation, evaporative cooling, ductwork, controls, and related HVAC systems within the permitted scope of the classification. Candidates should review the state classification description and make sure the license aligns with their intended services before applying.

Applicants should also understand that contractor licensing involves business structure, qualification, compliance, and documentation. The Application Service included in this Ultimate package helps organize the process so candidates are not left trying to navigate the paperwork alone after studying for the exam.
