Exam Details

The Arizona Air Conditioning and Refrigeration, Including Solar Residential / Commercial Contractor (CR-79) exam path includes the R-39/C-79 Air Conditioning and Refrigeration exam and the R-39/C-79 Solar exam. The Air Conditioning and Refrigeration exam includes 80 questions, allows 210 minutes, and requires a minimum passing score of 70%. The Solar exam includes 30 questions, allows 75 minutes, and requires a minimum passing score of 70%.

The Air Conditioning and Refrigeration exam 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, inspection, sizing, and estimating. These categories reflect the technical range expected from an HVAC/R contractor preparing for both residential and commercial air conditioning and refrigeration work.

The Solar exam content outline includes collection loops, components, installation, maintenance, mounting, principles, and solar systems piping. Candidates preparing for the CR-79 classification should plan for both the HVAC/R portion and the solar portion of the exam path. A complete study plan should include system knowledge, code familiarity, safety review, reference navigation, and solar-specific review.

Refrigeration preparation may include system components, refrigerant-cycle concepts, equipment operation, service considerations, controls, troubleshooting awareness, and safety practices. Air conditioning preparation may include comfort cooling, airflow, duct systems, equipment installation, mechanical requirements, and performance-related concepts. Warm air heating preparation may include heating equipment, air distribution, combustion-related concepts, controls, installation practices, and safety.

Controls and motors are also important exam topics. Candidates should understand basic control functions, motor operation, electrical awareness, system sequencing, safety considerations, and how controls affect HVAC/R system operation. Boilers, ventilation, evaporative coolers, piping systems, testing, balancing, inspections, sizing, and estimating should also be reviewed because each area contributes to the final exam score.

Because CR-79 includes solar, candidates should study solar system terminology, collection loops, system components, installation practices, maintenance concepts, mounting requirements, operating principles, and solar systems piping. Solar preparation should not be treated as an afterthought. It is a separate exam component and should be part of the study schedule from the beginning.

Open Book Test

The Arizona R-39/C-79 Air Conditioning and Refrigeration exam allows approved references in the examination center. The approved references included with this package are Code of Federal Regulations - 29 CFR Part 1926 (OSHA), International Fuel Gas Code, 2018, International Mechanical Code, 2018, and International Plumbing Code, 2018.

Open book does not mean the exam is simple. Candidates must understand the trade, recognize what each question is asking, select the correct reference, locate the correct section, and apply the information under timed conditions. A student who has not practiced using the references before test day may lose valuable time searching through unfamiliar books.

Approved references may be highlighted, underlined, annotated, and indexed before the examination session. Candidates may not write, highlight, underline, or add indexing to the books during the exam. Book preparation should be completed before the exam session so the materials are ready for use during testing.

References may be tabbed or indexed with permanent tabs only. Permanent tabs are tabs that would tear the page if removed. Temporary tabs, removable sticky notes, loose papers, and extra attached papers are not allowed in the exam room. This package supports preparation by providing books that are highlighted and tabbed for exam preparation.

The International Mechanical Code, 2018 supports preparation for mechanical systems, ventilation, ductwork, combustion air, exhaust systems, refrigeration provisions, and equipment installation.

Licensing Steps

Arizona contractor licensing is regulated by the Arizona Registrar of Contractors. Candidates pursuing the CR-79 Air Conditioning and Refrigeration, Including Solar residential/commercial classification should prepare for the required exams and complete the contractor licensing application process connected to the classification.

The licensing process generally begins with confirming that the CR-79 classification matches the work the contractor intends to perform. Arizona contractor licenses are classification-specific, so selecting the correct classification is an important first step. The CR-79 classification is intended for candidates seeking a dual residential/commercial air conditioning and refrigeration license that includes solar within the permitted scope.

After confirming the proper classification, candidates should prepare for the exam path. For CR-79 preparation, this means studying the R-39/C-79 Air Conditioning and Refrigeration exam topics and the R-39/C-79 Solar exam topics. Candidates should also practice using the approved references allowed for the exam-room portion of the process.

The contractor application process may include business information, qualifying party information, documentation, and other licensing materials required for the Arizona contractor license application. This Ultimate package includes Application Service support to help candidates stay organized while working through the licensing process.

Application Service is included because exam preparation and licensing paperwork are both important parts of the contractor licensing goal. Passing the required exams is a major step, but the application must also be completed properly. Organized support helps candidates keep the process moving while they focus on study, exam readiness, and the license application.

State Requirements

The Arizona CR-79 Air Conditioning and Refrigeration, Including Solar classification allows the scopes of work permitted by the commercial C-79 Air Conditioning and Refrigeration, Including Solar license and the residential R-39 Air Conditioning and Refrigeration, Including Solar license.
