The 1 Package: All-Inclusive Arizona Air Conditioning and Refrigeration Residential Contractor (R-39R) Exam, Licensing & Business Setup Solution

Prepare for the Arizona Air Conditioning and Refrigeration Residential Contractor R-39R exam while establishing the licensing and business foundation needed to operate professionally. The 1 Package combines HVAC exam preparation, approved exam-room references, supplemental study materials, contractor application assistance, business formation, EIN filing, and contractor compliance guidance in one complete solution.

This all-inclusive Arizona R-39R contractor package is designed for experienced HVAC technicians, refrigeration mechanics, heating professionals, qualifying parties, supervisors, and business owners pursuing an Arizona residential air conditioning and refrigeration contractor license. Instead of purchasing books, enrolling in a preparation course, organizing licensing documents, and establishing a business through separate providers, customers receive coordinated support throughout the process.

The preparation program addresses refrigeration, air conditioning, warm-air heating, controls and motors, boilers, ventilation, evaporative cooling, fuel piping, water piping, hydronic systems, testing, balancing, inspection, sizing, estimating, and construction safety. Candidates can strengthen their technical knowledge while practicing how to locate information efficiently in the references permitted during the examination.

The Arizona R-39R exam requires more than familiarity with HVAC terminology. Candidates may need to interpret code provisions, apply refrigeration principles, understand system components, evaluate fuel and water piping requirements, use duct-sizing tools, complete calculations, and recognize appropriate installation or service practices.

The package includes 1 year of course access, allowing candidates to prepare around work, project, and family responsibilities. The course provides an organized structure for reviewing technical subjects, completing practice-oriented preparation, and developing confidence with the books and tools included in the package.

The 1 Package also supports the licensing and business stages that follow examination preparation. Application Service helps organize the Arizona contractor licensing process. Business Formation establishes an LLC or corporation, EIN Filing supports professional business operations, and Contractor Compliance Guidance helps customers understand responsibilities associated with maintaining an Arizona residential HVAC contracting business.

Exam Details

The Arizona Registrar of Contractors administers contractor licensing in Arizona, and PSI administers the applicable air conditioning and refrigeration trade examination. The examination used for the residential R-39R and commercial C-39 classifications contains 80 questions.

Candidates are allowed 210 minutes to complete the examination and must earn a minimum score of 70 percent. The exam includes questions based on the listed references, trade knowledge, and general industry practices.

The examination content outline includes refrigeration, air conditioning, warm-air heating, controls and motors, boilers, ventilation, evaporative coolers, fuel piping systems, water piping systems, steam and hot, chilled, or condensing water systems, testing and balancing, inspections, sizing, and estimating.

Refrigeration, air conditioning, and warm-air heating account for significant portions of the examination. Candidates should understand refrigeration-cycle components, heat transfer, refrigerant behavior, system operation, heating equipment, airflow, electrical controls, motors, troubleshooting principles, and common installation procedures.

Additional questions address boilers, ventilation, evaporative cooling, fuel piping, water piping, hydronic systems, testing, balancing, inspection, sizing, and estimating. Preparation should therefore combine technical knowledge with code navigation, equipment familiarity, calculations, and practical field judgment.

The qualifying party is the person whose experience and examination qualifications support the contractor license. Passing the trade exam is an important step, but it does not automatically issue an Arizona contractor license. The Arizona Registrar of Contractors must review and approve the complete licensing application.

Applicants may also be required to complete Arizona’s Statutes and Rules Training Course and Exam unless an authorized waiver applies. This requirement is separate from the air conditioning and refrigeration trade examination and focuses on Arizona laws and rules affecting licensed contractors.

Open Book Test

The Arizona R-39R air conditioning and refrigeration examination is an open-book test with specific restrictions. Candidates may use only the references identified as permitted by the testing provider. Supplemental study books may help with preparation but cannot automatically be taken into the examination room.

An open-book examination still requires thorough preparation. Candidates have limited time to answer 80 questions, so searching every book from the beginning for each answer is not an effective strategy. Candidates should understand the major technical subjects and know which approved reference is most likely to contain the required information.

The official exam instructions allow candidates to highlight, underline, annotate, and index approved references before the examination session. Permanent tabs are permitted. Temporary tabs, such as removable notes or tabs that do not damage the page when removed, are not permitted.

Approved references may not contain additional loose or attached papers. Candidates may not write, highlight, underline, or add indexing during the examination. Materials are subject to inspection before the test begins.

A silent, nonprinting, nonprogrammable calculator is permitted at the examination center. Candidates should practice using a basic calculator for applicable HVAC calculations rather than relying on functions that may not be available during the test.

All books are highlighted and Tabbed. Regular practice with the prepared references helps candidates become familiar with chapter organization, code sections, permanent tab locations, definitions, tables, and commonly researched subjects.

Licensing Steps

1. Confirm the R-39R classification. Review the residential air conditioning and refrigeration scope and make sure it matches the services the business intends to provide.
2. Select the qualifying party. Identify the person who will satisfy the applicable experience and examination requirements for the contractor license.
3. Prepare for the trade examination. Use the included course, approved exam-room references, supplemental books, Ductulator, and practice-oriented study materials.
4. Complete the required examination process. Pass the applicable air conditioning and refrigeration examination and complete the Arizona Statutes and Rules requirement unless an authorized waiver applies.
5. Establish the business entity. Use the included Business Formation service to organize an LLC or corporation for the HVAC contracting business.
6. Obtain an EIN. Complete the included EIN Filing with the IRS for business banking, tax administration, payroll, hiring, and professional operations.
7. Organize the contractor application. Gather qualifying-party information, experience documentation, examination results, entity records, disclosures, and other required materials.
8. Complete applicable background requirements. Follow the Arizona licensing process for the individuals required to appear on the application.
9. Obtain the required contractor bond. Arrange the bond applicable to the residential specialty classification and anticipated volume of work.
10. Address residential financial protection. Complete the applicable Residential Contractors’ Recovery Fund requirement or authorized alternative.
11. Submit the application. Provide the completed application and supporting documents to the Arizona Registrar of Contractors.
12. Wait for license issuance. Do not offer or perform work requiring the R-39R contractor license until the state approves the application and issues an active license.

State Requirements

The R-39R license is an Arizona residential specialty contractor classification. It applies to residential air conditioning and refrigeration work within the classification’s authorized scope. Contractors intending to perform commercial work may require a commercial or dual classification.

The qualifying party must demonstrate the experience and knowledge required for the classification. Experience documentation may need to describe systems installed, repaired, serviced, or supervised; project types; technical responsibilities; and the duration of relevant HVAC experience.

The legal business entity applying for the license must be properly established and identified. The company name, ownership records, qualifying-party information, EIN documentation, contractor bond, and license application should remain consistent throughout the application process.

Arizona contractor applicants must satisfy applicable background, bonding, and financial-protection requirements. The required contractor bond depends on the license category and anticipated annual gross volume of work. Residential applicants must also address the applicable Residential Contractors’ Recovery Fund requirement or authorized alternative.

Passing the examination alone does not authorize a person or business to advertise, bid, contract, or perform work that requires an active Arizona contractor license. State approval of the complete application is required.

After licensing, the contractor must operate within the R-39R scope, maintain the required bond, renew the license, and keep business and qualifying-party information current. Changes involving ownership, the legal entity, address, bond, or qualifying party may require additional filings.
