Exam Details

The Arizona Air Conditioning and Refrigeration, Including Solar Commercial Contractor (C-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 range of knowledge expected from a commercial HVAC/R contractor working with mechanical systems, refrigeration equipment, heating systems, air handling equipment, and related piping.

The Solar exam content outline includes collection loops, components, installation, maintenance, mounting, principles, and solar systems piping. Candidates preparing for the C-79 classification should plan for both the HVAC/R portion and the solar portion of the exam path. A strong preparation plan should include system knowledge, code familiarity, safety review, and practice with exam-room-approved books.

Commercial HVAC/R work can involve larger equipment, more complex mechanical systems, broader piping considerations, and greater coordination with building systems than many residential projects. Candidates should be prepared to review topics connected to refrigeration, evaporative cooling, heating, ventilation, ductwork, controls, water piping, fuel gas piping, testing, balancing, and inspections.

Preparation should include both trade knowledge and reference navigation. Open-book exams reward candidates who know how to use the books efficiently. Students should practice using indexes, tables, definitions, chapter headings, and code sections so they can locate information quickly during the timed exam session.

Open Book Test

The Arizona C-79 Air Conditioning and Refrigeration, Including Solar commercial contractor exam path includes open-book reference use for the R-39/C-79 Air Conditioning and Refrigeration examination. Candidates are responsible for bringing their own approved reference materials to the examination center and following all exam-room rules for book preparation and reference use.

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. These books support preparation for safety, fuel gas, mechanical, plumbing, piping, and related HVAC/R questions.

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

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 notes, and extra attached papers are not allowed in the exam room. This package supports exam preparation by providing books that are highlighted and tabbed for exam preparation.

An open book test still requires careful study. Candidates need to recognize which book applies to a question, locate the correct section, interpret the information, and answer efficiently. For example, fuel gas questions may require use of the International Fuel Gas Code, mechanical system questions may require the International Mechanical Code, plumbing-related piping questions may require the International Plumbing Code, and safety questions may require OSHA 29 CFR Part 1926.

Licensing Steps

Arizona contractor licensing is regulated by the Arizona Registrar of Contractors. Candidates pursuing the C-79 Air Conditioning and Refrigeration, Including Solar commercial contractor 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 C-79 classification matches the commercial work the business intends to perform. Arizona contractor licenses are classification-specific, so selecting the correct classification is an important step. The C-79 classification is intended for commercial air conditioning and refrigeration work, including solar, within the scope permitted for that license.

After confirming the proper classification, candidates should prepare for the required examinations. For C-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 application process.

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

State Requirements

The Arizona C-79 Air Conditioning and Refrigeration, Including Solar classification allows commercial contractors to install, alter, and repair refrigeration and evaporative cooling systems, including solar. It also includes installation, alteration, and repair of heating systems of wet, dry, or radiant type.

The scope may include ventilation systems, ductwork, air filtering devices, water treatment devices, pneumatic or electrical controls, control piping, insulation of refrigerant pipes and ductwork, vibration isolation materials and devices, liquid fuel piping and tanks, water and gas piping from the service connection to the equipment served, and testing and balancing of refrigerant, cooling, heating circuits, and air handling systems.

The classification also includes installation and repair of machinery, units, accessories, refrigerator rooms, insulated refrigerated spaces, and controls in refrigerators. When necessary, a new circuit may be added to an existing service panel or sub-panel, but installation of a new service panel or sub-panel is excluded from the classification.

Candidates preparing for the C-79 classification should understand that this is a commercial specialty classification. It is different from a residential-only license and different from a dual residential/commercial license. The C-79 classification is intended for commercial contracting work within the air conditioning and refrigeration, including solar, scope.

State requirements are important because they define who may legally contract for regulated work in Arizona. Candidates should prepare for the required examinations, use the correct license classification, and complete the application process carefully. This package supports both the study side and the application side by combining approved books, course access, and Application Service.
