Exam Details

The Oklahoma Refrigeration Journeyman examination tests knowledge of the operation, installation, maintenance, repair, fabrication, alteration, and extension of refrigeration systems, including electrical components, piping, refrigerants, and refrigeration equipment.

The examination contains 60 questions. Candidates are allowed 150 minutes to complete the test. The required passing score is 70%, with 42 correct answers identified as the passing raw score.

The examination covers several major areas of refrigeration trade knowledge, including:

• Electrical knowledge and controls
• Refrigerants and refrigeration theory
• Refrigeration piping
• Refrigeration equipment and components
• System operation
• Installation, maintenance, and repair
• Troubleshooting
• Construction and workplace safety

Electrical Knowledge and Controls is an important part of the examination. Candidates should understand general electrical theory, motors, AC and DC circuits, meters, controls, relays, and the relationship between electrical components and refrigeration-system operation.

Refrigerants are another major area of preparation. Candidates should study refrigerant theory, pressure and temperature relationships, refrigerant characteristics, and how refrigerants move through the refrigeration cycle.

Refrigeration Equipment and Components requires familiarity with compressors, condensers, evaporators, valves, receivers, accumulators, expansion devices, dryers, and other components used in refrigeration systems.

Candidates should understand not only the purpose of individual components but also how they interact. Refrigeration systems operate as complete systems, so a problem affecting one component can influence pressures, temperatures, airflow, controls, and system performance elsewhere.

Refrigeration Systems Operations includes troubleshooting, installation, maintenance, and repair. Candidates should be prepared to evaluate system conditions, identify likely causes of operating problems, and understand the procedures used to service refrigeration equipment.

Open Book Test

The Oklahoma Refrigeration Journeyman examination is an open-book test. Candidates may use approved reference materials during the examination according to the examination provider's rules.

The listed technical references for preparation include the International Mechanical Code, 2018, Modern Refrigeration and Air Conditioning, and applicable 29 CFR Part 1926 OSHA construction safety material.

Approved reference materials may be highlighted, underlined, and indexed before the examination. Permanent tabs are permitted for organizing the references. Temporary tabs such as Post-it notes are not permitted.

The highlighted and tabbed format of this package is particularly useful for an open-book examination because candidates can practice with organized references before test day. Familiarity with the books can help reduce unnecessary searching when a detailed code, refrigeration, or safety lookup is required.

With 60 questions and 150 minutes available, candidates have an average of two and a half minutes per question. Some trade-knowledge questions can be answered quickly, while other questions may require a reference lookup or more detailed analysis.

A practical preparation strategy is to identify the subject first. A mechanical-code question may lead to the International Mechanical Code. A refrigeration theory, equipment, electrical-control, or troubleshooting question may lead to Modern Refrigeration and Air Conditioning. A construction safety question may require OSHA 29 CFR Part 1926.

Regular practice using this method can help candidates build a more efficient approach to open-book testing.

State Requirements

Oklahoma mechanical licensing is administered through the Oklahoma Construction Industries Board. Applicants for a mechanical journeyman license must be at least 18 years old and meet one of the state's qualifying experience or education pathways.

A standard qualification pathway requires three years of verifiable experience in the mechanical trade in the category for which the applicant is seeking a license.

Oklahoma also recognizes qualifying combinations of approved mechanical education and field experience. An approved associate degree or vocational diploma consisting of at least 1,000 hours may be combined with one year of verifiable mechanical experience. Other approved educational programs may reduce the amount of field experience required according to the applicable state requirements.

Equivalent verifiable mechanical experience gained while serving in the U.S. military may also qualify. An applicant may also qualify through a current out-of-state mechanical license in the applicable classification when the license is in good standing and meets Oklahoma's qualification requirements.

For Oklahoma mechanical licensing purposes, one year of verifiable experience equals 2,000 hours. Verifiable experience generally means mechanical experience obtained while employed by a licensed Mechanical Contractor or through another method accepted by the Committee of Mechanical Examiners.

Applicants who are not already licensed and want to use experience gained in Oklahoma toward the licensing requirement must maintain the applicable apprentice registration for qualifying Oklahoma work experience.

The Refrigeration Journeyman classification authorizes the license holder to install, alter, modify, service, maintain, or repair refrigeration products, systems, or equipment, including associated process piping.

After licensing, a Refrigeration Journeyman works within Oklahoma's mechanical licensing structure and performs work for an appropriately licensed Mechanical Contractor. Journeymen must remain within the scope of the refrigeration classification and comply with applicable state mechanical laws and regulations.

Test Information and Study Materials

A strong Oklahoma Refrigeration Journeyman study plan should combine refrigeration trade knowledge with mechanical code review and repeated reference-navigation practice.

Start with refrigeration theory. Candidates should understand the refrigeration cycle and how refrigerant changes pressure, temperature, and physical state as it moves through a system. A strong understanding of the basic cycle makes equipment and troubleshooting questions easier to analyze.

Review refrigerants carefully. Learn the principles governing refrigerant operation and how system pressures and temperatures relate to performance. Candidates should understand the role refrigerant plays in absorbing and rejecting heat.

Study electrical knowledge and controls. Refrigeration equipment relies on electrical circuits, motors, relays, switches, and controls. Review AC and DC principles, meters, motor operation, and control sequences so electrical questions can be considered in the context of complete refrigeration systems.

Understand compressors. The compressor is a major component of the refrigeration cycle. Candidates should understand its purpose and recognize how compressor operating conditions can affect the rest of the system.

Review condensers and evaporators. Candidates should understand how these heat-transfer components function and how airflow, refrigerant conditions, and equipment performance affect their operation.

Study expansion devices and valves. Review how metering devices regulate refrigerant flow and how different valves perform control, isolation, or system-management functions.

Review receivers, accumulators, and dryers. Candidates should understand the general role these components play in managing refrigerant, protecting equipment, and maintaining proper system operation.

Practice refrigeration piping topics. Study piping materials, sizing, support, installation, and pressure testing. Proper refrigeration piping is important for reliable equipment operation and effective refrigerant movement.

Build troubleshooting skills. Rather than memorizing isolated symptoms, practice connecting system conditions to possible causes. Consider pressures, temperatures, refrigerant charge, airflow, electrical controls, compressor operation, metering devices, condensers, and evaporators together.

Review installation, maintenance, and repair. Candidates should understand the practical responsibilities involved in putting refrigeration equipment into service and keeping systems operating properly.

Study construction safety. Use the OSHA reference to review workplace hazards applicable to mechanical and refrigeration work. Safety preparation should include personal protective equipment, ladders, tools, hazardous materials, ventilation, and other applicable construction-safety subjects.

Practice mechanical code navigation. Use the International Mechanical Code while studying so locating definitions, refrigeration provisions, installation requirements, equipment rules, and piping-related information becomes more familiar.

Timed study sessions can help candidates develop exam pacing. Since the examination allows 150 minutes for 60 questions, practice completing straightforward questions efficiently while preserving additional time for detailed lookups and more complex troubleshooting questions.

The highlighted and tabbed books can support this preparation by making major subject areas easier to locate. Candidates should still understand the surrounding material and learn the overall organization of each reference rather than depending entirely on highlighted passages.
