The 1 Package: All-Inclusive Arizona Evaporative Cooling and Ventilating Residential / Commercial Contractor (CR-58) Exam, Licensing & Business Setup Solution

Prepare for the Arizona Evaporative Cooling and Ventilating Residential / Commercial Contractor CR-58 exam while building the licensing and business foundation needed to operate professionally. The 1 Package combines trade exam preparation, approved code books, supplemental HVAC study materials, contractor application assistance, business formation, EIN filing, and contractor compliance guidance in one organized solution.

This all-inclusive Arizona CR-58 contractor package is designed for experienced HVAC technicians, evaporative-cooling installers, ventilation specialists, duct-system professionals, project supervisors, qualifying parties, and business owners pursuing residential and commercial contracting authority in Arizona.

The CR-58 classification combines the work permitted by Arizona’s commercial C-58 Comfort Heating, Ventilating and Evaporative Cooling classification with the residential R-39R Warm Air Heating, Evaporative Cooling and Ventilating classification. This makes the package relevant to candidates planning to work on qualifying systems in both residential and commercial environments.

Preparation covers warm-air heating, evaporative cooling equipment, ventilation, duct systems, piping, controls, motors, testing, inspections, system sizing, estimating, mechanical codes, fuel-gas provisions, plumbing connections, and OSHA construction safety. Candidates also receive supplemental resources for residential duct design, load calculations, and modern HVAC system fundamentals.

Evaporative cooling and ventilation work requires more than familiarity with equipment. Contractors must understand airflow, equipment placement, duct sizing, water supply, drainage, controls, electrical connections within the classification scope, fuel-gas requirements, combustion air, venting, supports, access, and safe installation practices.

The package includes 1 year of course access, giving candidates time to study around employment, active projects, and personal responsibilities. The course supports organized trade review, practice-oriented preparation, code navigation, calculation work, and repeated use of the included reference materials.

The 1 Package also supports the licensing and business stages that follow exam preparation. Application Service helps organize the Arizona contractor license process. Business Formation establishes an LLC or corporation, EIN Filing supports banking and tax administration, and Contractor Compliance Guidance helps customers understand responsibilities associated with operating an Arizona residential and commercial HVAC contracting business.

Exam Details

The Arizona CR-58 Warm Air Heating, Evaporative Cooling and Ventilating examination is administered through PSI for the Arizona Registrar of Contractors. It measures the trade knowledge needed to supervise or perform work associated with the classification.

The examination contains 60 questions. Candidates are allowed 150 minutes and must earn a minimum score of 70 percent to pass. Additional unscored experimental questions may appear and count against the available examination time.

The exam outline includes warm-air heating, ventilation, controls and motors, sizing and estimating, piping and tubing, ducts and insulation, evaporative cooling, inspections, and testing. Candidates should prepare for both code-based questions and questions that require practical HVAC knowledge.

Warm-air heating preparation may include gas-fired furnaces, space heaters, combustion air, burners, equipment access, clearances, venting, controls, air distribution, return air, and installation requirements. Candidates should understand the interaction among fuel supply, combustion, airflow, venting, and equipment operation.

Evaporative-cooling study may include cooler components, pads, pumps, water distribution, sumps, floats, bleed-off systems, ducts, supports, controls, maintenance, drainage, and equipment placement. Candidates should understand how airflow, water quality, climate conditions, and maintenance affect performance.

Ventilation preparation may involve natural and mechanical ventilation, exhaust systems, air movement, fans, intake and discharge locations, duct connections, required clearances, and system controls. Questions may address residential and commercial applications.

Duct-system study may include sizing, layout, materials, fittings, sealing, supports, insulation, vibration isolation, supply air, return air, pressure losses, airflow, and balancing. Manual D and the Ductulator support preparation for duct-design concepts even though they are supplemental study materials rather than approved exam-room references.

Controls and motors preparation may involve thermostats, relays, switches, transformers, motor principles, control wiring, disconnects, overcurrent protection concepts, and equipment sequences. Work must remain within the electrical authority permitted by the CR-58 classification.

Piping and tubing preparation may include fuel-gas piping, water supply, condensate or drainage considerations, materials, supports, valves, sizing, testing, and connections to HVAC equipment. Candidates should know which requirements are found in the fuel-gas, mechanical, and plumbing codes.

Passing the trade examination does not automatically issue the CR-58 license. The Arizona Registrar of Contractors must review and approve the complete contractor application before the business may operate under the classification.

Open Book Test

The Arizona CR-58 trade examination is an open-book test using approved reference materials. Candidates may consult permitted books during the examination under PSI’s current rules for editions, highlighting, annotations, indexing, tabs, and book inspection.

An open-book exam still requires organized preparation. Candidates have limited time to identify the subject, select the correct book, locate the relevant section, interpret the requirement, and apply it to the system or installation described in the question.

All books are highlighted and Tabbed. Highlighting draws attention to useful safety standards, code sections, equipment requirements, definitions, tables, formulas, and installation provisions. Tabs help candidates move among major chapters and commonly researched topics more efficiently.

The prepared books should be used throughout the course. Repeated code-navigation practice helps candidates learn where fuel-gas, mechanical, plumbing, and safety requirements are located. Familiarity with indexes, tables, exceptions, diagrams, and permanent tabs can reduce unnecessary searching.

A question involving furnace venting, fuel-gas piping, appliance connections, or combustion air may require the International Fuel Gas Code. Equipment, duct, ventilation, and mechanical-system questions may require the International Mechanical Code.

Questions involving water supply, drainage, traps, piping materials, or plumbing connections may require the International Plumbing Code. Construction-site hazards, ladders, tools, fall protection, electrical safety, and personal protective equipment may be addressed by OSHA.

The Ductulator, Manual D, Manual J, and Modern Refrigeration and Air Conditioning are supplemental preparation resources. They support study of airflow, duct sizing, load calculations, system design, equipment, and HVAC fundamentals, but they are not identified as approved exam-room references for the CR-58 examination.

All approved books remain subject to inspection. Temporary tabs, removable notes, loose papers, electronic materials, and unauthorized attachments are not permitted. Candidates may use a basic, silent, nonprinting, nonprogrammable, nonscientific calculator under PSI’s examination rules.

Licensing Steps

1. Confirm the CR-58 classification. Review the residential and commercial scope to make sure it matches the heating, ventilation, and evaporative-cooling services the business plans to offer.
2. Select the qualifying party. Identify the person who will satisfy the applicable experience, knowledge, and examination requirements.
3. Review the examination requirements. Determine which trade and Arizona Statutes and Rules requirements apply to the proposed qualifying party.
4. Prepare for the CR-58 exam. Use the included course, highlighted and tabbed books, HVAC review, code-navigation drills, and practice-oriented study materials.
5. Complete the required examinations. Pass the trade examination and complete Arizona’s Statutes and Rules requirement unless an authorized waiver applies.
6. Form the business entity. Use the included Business Formation service to establish an LLC or corporation for the contracting business.
7. Obtain an EIN. Complete the included EIN Filing with the IRS for business banking, tax administration, hiring, and professional operations.
8. Complete applicable background requirements. Follow Arizona’s background-check process for the individuals required to appear on the application.
9. Prepare the contractor application. Organize qualifying-party records, experience information, examination results, business documents, and required disclosures.
10. Obtain the contractor license bond. Arrange the bond required for the dual classification and anticipated annual gross volume of work.
11. Address residential financial protection. Complete the applicable Residential Contractors’ Recovery Fund requirement or authorized alternative.
12. Submit the application. Provide the completed contractor license application and supporting materials to the Arizona Registrar of Contractors.
13. Wait for license issuance. Do not advertise, contract for, or perform work requiring the CR-58 license until the state approves the application and issues an active license.

State Requirements

The CR-58 classification allows the scopes permitted by the commercial C-58 Comfort Heating, Ventilating and Evaporative Cooling license and the residential R-39R Warm Air Heating, Evaporative Cooling and Ventilating license.

The classification covers qualifying installation, alteration, and repair of warm-air heating systems, gas-fired furnaces, space heaters, ventilation systems, and evaporative-cooling units. Associated work may include ductwork, controls, insulation, fuel piping, water piping, system testing, and balancing within the authorized scope.

When necessary for covered work, the classification permits adding a new circuit to an existing service panel or subpanel. Installation of a new service panel or subpanel is excluded.

The proposed qualifying party must demonstrate the experience, knowledge, and skills needed to supervise or perform the classification’s work. Experience documentation may need to describe HVAC installations, evaporative coolers, ventilation, furnaces, ducts, piping, controls, testing, and supervisory responsibilities.

The applicant’s legal business entity must be properly formed and identified. The business name, ownership records, qualifying-party information, EIN documents, bond, and contractor application should remain consistent throughout the licensing process.

A contractor license bond is required. Because CR-58 is a dual classification, the bond requirement combines the applicable residential and commercial bond amounts based on the anticipated volume of work.

The residential portion of the license is also subject to Arizona’s residential financial-protection requirements. The applicant must pay the applicable Residential Contractors’ Recovery Fund assessment or provide the authorized alternative protection.

Passing the required examination is one part of the process. The applicant may not perform regulated CR-58 contracting work until the Arizona Registrar of Contractors approves the complete application and issues the license.
