Exam Details

The Arizona Air Conditioning and Refrigeration Residential / Commercial Contractor (CR-39) trade exam is used for candidates pursuing the Arizona dual residential/commercial air conditioning and refrigeration contractor classification. The exam includes 80 questions, allows 210 minutes, and requires a minimum passing score of 70%.

The exam content includes refrigeration, air conditioning, warm air heating, controls and motors, boilers, ventilation, evaporative coolers, fuel piping systems, water piping systems, steam, hot, chilled, and condensing water, testing, balancing, inspections, sizing, and estimating. These categories reflect the wide technical range expected of an HVAC/R contractor working in both residential and commercial environments.

Refrigeration topics may involve system components, refrigeration principles, equipment operation, installation practices, troubleshooting concepts, and safety considerations. Air conditioning topics may include comfort cooling, system layout, mechanical requirements, airflow, duct-related concepts, equipment installation, and operational performance. Warm air heating topics may involve heating system components, combustion-related concepts, air distribution, equipment installation, and service-related knowledge.

Controls and motors are also part of the exam outline. Candidates should understand basic control concepts, motor operation, system control sequences, electrical safety awareness, and how HVAC/R equipment depends on properly operating control systems. Even when a candidate has hands-on field experience, exam questions may require careful reading and the ability to connect field knowledge with code language or reference-book information.

The exam also includes boilers, ventilation, evaporative coolers, fuel piping systems, water piping systems, steam, hot, chilled, and condensing water, testing, balancing, inspections, sizing, and estimating. These areas require candidates to prepare beyond the most common air conditioning topics. A strong study plan should include time for smaller content areas because each category can affect the final exam score.

Since the exam allows approved references, preparation should include more than reading the books. Candidates should practice locating information by using the table of contents, indexes, chapter headings, definitions, tables, and code sections. The more familiar a student becomes with the structure of each reference, the easier it is to move through exam questions efficiently.

Open Book Test

The Arizona CR-39 Air Conditioning and Refrigeration residential/commercial trade exam is an open book test. Candidates may bring approved references into the examination center, but the books must follow the testing rules. The approved exam-room references for this package are the Code of Federal Regulations - 29 CFR Part 1926 (OSHA), International Fuel Gas Code, 2018, and International Mechanical Code, 2018.

Open book does not mean the exam is easy. Candidates still need to understand the trade, recognize the subject being tested, and find information quickly. The approved references are valuable during the exam, but only when the candidate has practiced using them. A student who waits until test day to open the books may lose valuable time searching through unfamiliar sections.

Approved references may be prepared before the exam with allowed markings such as highlighting, underlining, annotations, and indexing. Books may be tabbed with permanent tabs. Permanent tabs are the type that would tear the page if removed. Temporary tabs, loose notes, removable sticky notes, and extra papers are not allowed in the exam room.

During the exam, candidates may not write, highlight, underline, or add new indexing to the books. All book preparation should be completed before the exam session. This is why organized, pre-highlighted, and tabbed books are helpful for candidates preparing for an open book contractor exam. Clear book organization can support faster navigation and reduce stress during timed testing.

This package is especially useful for candidates who want the correct books prepared for exam study and reference navigation. Since the CR-39 exam includes mechanical, fuel gas, and safety-related topics, each book has a purpose in preparation. The International Mechanical Code supports mechanical system questions, the International Fuel Gas Code supports fuel gas questions, and OSHA 29 CFR Part 1926 supports construction safety knowledge.

Licensing Steps

Arizona contractor licensing is handled through the Arizona Registrar of Contractors. Candidates pursuing the CR-39 Air Conditioning and Refrigeration residential/commercial classification should prepare for the required trade exam and complete the contractor licensing application process for the classification they are seeking.

The licensing process generally begins with confirming that the CR-39 classification matches the type of work the contractor intends to perform. Because Arizona contractor licenses are classification-specific, choosing the correct classification is an important step. The CR-39 classification is for candidates seeking a residential/commercial air conditioning and refrigeration contractor license pathway.

After identifying the correct classification, candidates should prepare for the required exam. Exam preparation should include reviewing the content outline, studying HVAC/R trade topics, learning the approved references, and practicing how to locate code information efficiently. Candidates should also prepare for any additional licensing requirements connected to the contractor application process.

The application process may involve business information, qualifying party information, documentation, and other licensing materials required by the Arizona Registrar of Contractors. This Ultimate package includes Application Service support to help candidates organize the application portion of the process while also preparing for the exam.

Application Service is included to help reduce confusion during the licensing process. Many candidates focus heavily on the trade exam but underestimate the importance of submitting accurate and complete application materials. A well-organized application process can help candidates move forward with less frustration and fewer avoidable delays.

Passing the exam is an important part of becoming licensed, but it is not the only step. Candidates must also complete the required licensing process and meet the applicable state requirements. This package supports both sides of the preparation path by combining exam-room-approved books, course access, and application support.

State Requirements

The Arizona CR-39 Air Conditioning and Refrigeration classification is a residential/commercial contractor classification. It is connected to air conditioning and refrigeration work and combines the residential and commercial scope for this specialty area. Contractors pursuing this classification should be prepared to demonstrate knowledge of HVAC/R systems, safety, code requirements, and trade practices.

Arizona contractor licensing is regulated by the Arizona Registrar of Contractors. Applicants must follow the licensing process for the classification they are seeking and satisfy the requirements connected to that license. Since contractor licensing requirements can include more than the trade exam, candidates should treat exam preparation and application preparation as connected parts of the same goal.

The CR-39 classification is intended for contractors working in air conditioning and refrigeration across residential and commercial settings. Work in this trade may involve equipment installation, alteration, maintenance, repair, ventilation, heating, refrigeration, evaporative cooling, ductwork, controls, and related HVAC/R systems within the scope of the classification.

State requirements are important because they define who may legally contract for regulated work in Arizona. Candidates should prepare carefully, use the correct license classification, and submit required materials properly. This package supports candidates by helping them study for the trade exam while also receiving Application Service support for the licensing process.

For exam preparation, candidates should focus on the topics listed in the CR-39 content outline and the approved references used for the exam. For licensing preparation, candidates should focus on completing the application process accurately and organizing the required information. A complete preparation approach helps candidates avoid treating the exam and application as separate, disconnected tasks.

Test Information and Study Materials

The Arizona CR-39 exam includes 80 questions and allows 210 minutes. The passing score is 70%. The content outline includes refrigeration, air conditioning, warm air heating, controls and motors, boilers, ventilation, evaporative coolers, fuel piping systems, water piping systems, steam, hot, chilled, and condensing water, testing, balancing, inspections, sizing, and estimating.

A strong study plan should begin with the largest topic areas while still giving attention to every category. Refrigeration, air conditioning, and warm air heating represent major parts of the exam. These subjects should be reviewed carefully because they cover core HVAC/R work and may involve both trade knowledge and reference-book use.

Fuel piping systems should be studied with the International Fuel Gas Code, 2018. Candidates should practice locating requirements related to fuel gas piping, pipe sizing concepts, installation rules, appliance connections, combustion air, venting, and safety provisions. Since fuel gas topics require code familiarity, students should be comfortable using the index and table of contents in the fuel gas code book.

Mechanical topics should be studied with the International Mechanical Code, 2018. Candidates should review ventilation, duct systems, exhaust systems, equipment installation, refrigeration-related requirements, combustion air, and mechanical system provisions. Candidates should also practice reading tables and identifying the correct code section for a question.

Safety topics should be reviewed with the Code of Federal Regulations - 29 CFR Part 1926 (OSHA). Safety knowledge is important for contractors because construction work involves jobsite hazards, employee protection, equipment safety, and safe work practices. Exam preparation should include familiarity with OSHA construction safety topics and how to locate relevant information in the reference.

The included course helps candidates study with structure. Instead of reviewing books randomly, students can use the course to guide preparation, reinforce trade concepts, and build confidence with practice-oriented review. Course access gives students 1 year to work through material at a manageable pace.

Time management is also important. With 80 questions and 210 minutes, candidates have limited time for each question. Some questions may be answered through trade knowledge, while others may require reference-book lookup. Candidates should avoid spending too long on any single question and should practice using the books efficiently before exam day.

Good study habits include reviewing the content outline, practicing reference navigation, learning common HVAC/R terms, reading code sections carefully, working through practice questions, and building a routine. Candidates should prepare early enough to become comfortable with both the exam content and the approved references.

The exam-room-approved books included in this package are not general reading materials only. They are tools that support exam preparation and exam-room performance. Highlighting and tabs can make the books easier to use, but candidates still need to understand how each book is structured and when to use each reference.
