Candidates may not write, highlight, underline, or index references during the examination session. Additional papers, whether loose or attached, are not permitted with the approved references.

References may be tabbed or indexed with permanent tabs only. Permanent tabs are tabs that would tear the page if removed. Temporary removable tabs, including Post-It notes or similar removable tabs, are not allowed and must be removed before the exam begins. Downloaded references may be brought into the testing center when properly bound, such as spiral binding or hole-punched pages placed in a binder.

A silent, nonprinting, non-programmable calculator may be used in the examination center. Since the exam allows 150 minutes for 60 questions, students should practice pacing before test day. The open book format can be helpful, but only when students know where important information is located and can move through the references efficiently.

Licensing Steps

The Arizona Registrar of Contractors licenses and regulates contractors in Arizona. Candidates pursuing the Arizona CR-58 Evaporative Cooling and Ventilating Residential / Commercial Contractor license should follow the Arizona ROC licensing process for the classification and business structure they plan to use.

The qualifying party is the person who completes the examination requirements for the license classification. For many applicants, the licensing process includes completing the required trade examination, completing the Arizona Statutes and Rules Training Course and Exam when required, preparing business and identification documents, completing background check requirements, obtaining the required contractor license bond, and submitting the license application to the Arizona ROC.

A practical licensing path for the Arizona CR-58 contractor license includes:

1. Confirm that the CR-58 Evaporative Cooling and Ventilating classification matches the residential and commercial work the business intends to perform.
2. Prepare for the CR-58 trade examination using the listed references and online exam prep materials.
3. Study warm air heating, ventilation, controls, motors, piping, tubing, ducts, insulation, evaporative cooling, sizing, estimating, inspections, testing, and OSHA safety.
4. Complete the Arizona Statutes and Rules Training Course and Exam when required by the Arizona ROC.
5. Prepare identification, background check, qualifying party, ownership, and business documentation.
6. Obtain the required contractor license bond for the residential and commercial license classification.
7. Submit the completed Arizona contractor license application and required fees through the Arizona ROC process.
8. Respond to any application corrections or document requests from the Arizona Registrar of Contractors.

The trade exam is only one part of the licensing process. Passing the CR-58 exam does not automatically issue the contractor license. The Arizona ROC reviews the license application and supporting documents before granting the license. Applicants should make sure business names, ownership records, qualifying party information, and required documents are consistent before submitting the application.

State Requirements

The Arizona CR-58 Evaporative Cooling and Ventilating classification is a dual residential and commercial specialty contractor classification. It allows the scopes of work permitted by the commercial C-58 Comfort Heating, Ventilating, Evaporative Cooling license and the residential R-39R Warm Air Heating, Evaporative Cooling, and Ventilating license.

The scope includes installation, alteration, and repair of warm air heating systems, gas-fired furnaces and space heaters, ventilation and evaporative cooling units, or any combination of these. Systems may include duct work, air filtering devices, pneumatic or electrical controls, control piping, thermal and acoustical insulation, vibration insulation 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 air handling systems.

If necessary, a new circuit may be added to the existing service panel or sub-panel. Installation of a new service panel or sub-panel is excluded. Students preparing for the CR-58 license should understand this boundary because electrical work outside the authorized scope may require a separate license classification or additional authorization.

Arizona contractor applicants should understand that licensing involves both exam readiness and application readiness. The Arizona ROC may require trade examination completion, SRE completion when applicable, background checks, bonding, fees, and complete application documentation. The contractor license is issued through the Arizona ROC, not through the testing provider.
