Open Book Test

The Arizona CR-79 Air Conditioning and Refrigeration, Including Solar exam is an open book test using approved references. Candidates are responsible for bringing their own approved reference materials to the examination center and preparing those books according to the testing rules before exam day.

Open book testing rewards preparation, organization, and book familiarity. Candidates should not wait until the exam begins to learn the references. A stronger approach is to study the table of contents, indexes, definitions, tables, chapter organization, and commonly used sections before test day. The more familiar the books become during practice, the more useful they are under timed testing conditions.

Approved references may be highlighted, underlined, annotated, and indexed before the examination session. Candidates may not write, highlight, underline, or index their references during the exam. Additional loose papers or attached papers are not permitted with approved references. Permanent tabs are allowed, while temporary removable tabs are not allowed.

The books should be organized before test day according to testing rules. Candidates should practice choosing the correct reference for each type of question. Fuel gas questions may require the International Fuel Gas Code, mechanical system questions may require the International Mechanical Code, plumbing or piping questions may require the International Plumbing Code, and safety questions may require OSHA 29 CFR Part 1926.

An open book exam is still timed. With a large number of questions and multiple subject areas, candidates need to work steadily and avoid spending too much time searching for one answer. Practice with the approved references helps improve pacing, reduce stress, and build a stronger exam strategy.

Licensing Steps

Arizona contractor licensing is handled by the Arizona Registrar of Contractors. Candidates pursuing the Arizona Air Conditioning and Refrigeration, Including Solar Residential / Commercial Contractor (CR-79) classification should follow the official Arizona Registrar of Contractors licensing process for current application requirements, classification rules, examination instructions, forms, and supporting documentation.

A typical preparation path begins by confirming that the CR-79 dual classification matches the work the candidate intends to perform. Since CR-79 is a residential and commercial classification, it is intended for contractors seeking coverage across both residential and commercial air conditioning and refrigeration, including solar, scopes.

After confirming the classification, candidates should prepare for the required examination process, study the approved references, complete the testing requirements, and submit licensing materials according to Arizona Registrar of Contractors instructions. Contractor licensing may involve more than the trade exam, including requirements related to a qualifying party, experience, business structure, bonds, background checks, financial information, statutes and rules, and application documentation.

This Books & Courses Rental Package supports the exam preparation portion of the licensing journey. It does not replace the official application, state review, or approval process. The package is intended to help candidates study for the CR-79 exam path using the listed rental books and organized course access.

State Requirements

Arizona issues separate licenses for commercial work, residential work, and dual residential/commercial work within specific trades. The CR-79 classification is a dual residential and commercial classification connected to air conditioning and refrigeration, including solar. Candidates should make sure this classification matches the work they intend to contract for in Arizona.

The residential scope includes installation and repair of comfort air conditioning systems, including refrigeration, evaporative cooling, ventilating, and heating with or without solar equipment. It also includes installation and repair of machinery, units, accessories, refrigerator rooms, insulated refrigerated spaces, and controls in refrigerators.

The commercial scope includes installation, alteration, and repair of refrigeration and evaporative cooling systems, heating systems, ventilation systems, duct work, air filtering devices, water treatment devices, pneumatic or electrical controls, control piping, thermal and acoustical insulation of refrigerant pipes and ductwork, vibration isolation materials and devices, liquid fuel piping and tanks, and water and gas piping from the service connection to the equipment served.

The classification also includes testing and balancing of refrigerant, cooling, heating circuits, and air handling systems within the scope. If necessary, a new circuit may be added to an existing service panel or sub-panel, while installation of a new service panel or sub-panel is excluded.

Because the classification includes solar, candidates should also prepare for solar-related concepts within the exam path, including collection loops, components, installation, maintenance, mounting, principles, and solar systems piping. Choosing the correct classification matters because a contractor license defines the type of work a licensee is permitted to perform.
