Exam Details

The Oklahoma Refrigeration Journeyman examination tests knowledge of the operation, installation, maintenance, repair, fabrication, alteration, and extension of refrigeration systems while working for a licensed Refrigeration Contractor. The examination includes electrical components, piping, refrigerants, refrigeration equipment, system operation, troubleshooting, and safety.

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 is divided into six major content areas:

• Electrical Knowledge and Controls: 15 questions
• Refrigerants: 17 questions
• Piping: 3 questions
• Refrigeration Equipment and Components: 15 questions
• Refrigeration Systems Operations: 5 questions
• Safety: 5 questions

Refrigerants is the largest individual examination category, accounting for 17 questions. Candidates should understand refrigerant types, refrigeration systems, and refrigeration theory. Studying how refrigerant conditions change throughout a system can help candidates interpret technical questions involving pressures, temperatures, heat transfer, and system performance.

Electrical Knowledge and Controls accounts for 15 questions. This section includes general electrical theory, motors, AC and DC circuits, meters, controls, and relays. Refrigeration equipment depends heavily on electrical controls, so candidates should be comfortable connecting electrical principles with system operation.

Refrigeration Equipment and Components also accounts for 15 questions. Candidates should study valves, compressors, condensers, evaporators, receivers, accumulators, expansion devices, and dryers. Understanding the purpose of individual components and how they work together is important for both installation and troubleshooting.

Piping includes piping supports, materials and sizes, and pressure testing. Refrigeration Systems Operations covers troubleshooting, system operation, installation, maintenance, and repair. Safety covers important workplace protection requirements relevant to refrigeration work.

Open Book Test

The Oklahoma Refrigeration Journeyman examination is an open-book test. Candidates may bring approved reference materials into the examination center and use them while answering questions.

The approved references include the International Mechanical Code, 2018, Modern Refrigeration and Air Conditioning, including the 22nd Edition, and the applicable Code of Federal Regulations - 29 CFR Part 1926 (OSHA) construction safety material.

Reference materials may be highlighted, underlined, and indexed before the examination session. Permanent tabs may be used to organize the approved books. Temporary tabs such as Post-it notes are not permitted.

Written notes may not be added to references before or during the examination. Candidates should prepare with the books in a format that complies with exam-center requirements.

The open-book format makes efficient reference navigation important. Candidates have 150 minutes to answer 60 questions, which averages two and a half minutes per question. Searching through unfamiliar books for every answer can quickly consume available testing time.

A stronger strategy is to identify the subject before opening a reference. A mechanical-code question may lead to the International Mechanical Code. A refrigeration theory, electrical control, equipment, or troubleshooting question may be addressed in Modern Refrigeration and Air Conditioning. A safety question may require OSHA 29 CFR Part 1926.

Using the highlighted and tabbed rental books during study can help candidates become more familiar with the location of important material and build a more efficient approach to open-book testing.

State Requirements

The Oklahoma Construction Industries Board administers mechanical journeyman licensing. Applicants for a mechanical journeyman license must be at least 18 years old and meet one of the qualifying experience or education pathways established by Oklahoma.

A standard qualification pathway requires three years of verifiable experience in the mechanical trade in the category for which the candidate is applying.

Oklahoma also recognizes qualifying mechanical education combined with trade 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. Additional approved educational pathways with fewer classroom hours require greater amounts of verifiable experience.

Equivalent verifiable mechanical experience gained while serving in the U.S. military may also qualify. Oklahoma may also recognize an out-of-state mechanical license when it is current, in good standing, and meets the applicable qualification requirements.

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

Applicants using mechanical work performed in Oklahoma toward their experience requirement generally must maintain the applicable apprentice registration so that the experience can be recognized as verifiable.

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

A licensed Refrigeration Journeyman works within Oklahoma's mechanical licensing structure and performs refrigeration work while employed by an appropriately licensed contractor. Journeymen must remain within the scope of their license classification and comply with applicable mechanical laws and regulations.

Oklahoma mechanical journeymen are also subject to continuing education requirements. Mechanical journeymen and contractors are required to complete six hours of approved continuing education every 36 months.

Test Information and Study Materials

A strong Oklahoma Refrigeration Journeyman study plan should give additional attention to refrigerants, electrical controls, and refrigeration equipment because those three categories account for most of the examination.

Refrigerants represent the largest content area. Review refrigerant types, refrigeration-system theory, pressure-temperature relationships, and how refrigerant changes condition throughout the refrigeration cycle. Candidates should understand how refrigerant behavior relates to system operation and troubleshooting.

Electrical Knowledge and Controls requires familiarity with electrical theory, motors, AC and DC circuits, meters, controls, and relays. Practice understanding how electrical components start, stop, regulate, and protect refrigeration equipment.

Refrigeration Equipment and Components should include valves, compressors, condensers, evaporators, receivers, accumulators, expansion devices, and dryers. Review each component independently and then study how all components interact within a complete system.

Piping preparation should include piping supports, material selection, sizing, and pressure testing. Candidates should understand why properly installed refrigeration piping is important for system operation and reliability.

Refrigeration Systems Operations includes troubleshooting, system operation, installation, maintenance, and repair. Candidates should practice evaluating refrigeration problems based on system symptoms rather than memorizing isolated answers.

When troubleshooting, consider the interaction between electrical controls, refrigerant conditions, pressures, temperatures, airflow, piping, compressors, condensers, evaporators, and metering devices. Refrigeration systems operate as connected systems, and a problem in one area can affect conditions elsewhere.

Safety preparation should include safety training requirements, ventilation, first aid, personal protective equipment, safety data information, work around toxic materials, lockout/tagout procedures, and ladders.

Reference navigation should be practiced throughout the study process. Candidates should identify the question topic first and then determine which reference is most likely to contain the information. Using this approach can reduce unnecessary searching during an open-book examination.

The highlighted and tabbed rental references are designed to support this type of preparation. Use the tabs to move between important areas, but also learn how each book is organized so you can find material that may not be immediately visible from a tab.

Timed practice can help develop appropriate exam pacing. With 60 questions and 150 minutes, candidates should practice answering familiar trade-knowledge questions efficiently while preserving additional time for detailed calculations, troubleshooting, and code lookups.

How 1 Exam Prep Helps You Reach Your Goal

1 Exam Prep supports Oklahoma Refrigeration Journeyman candidates through organized study guidance, refrigeration-focused review, practice-oriented preparation, reference navigation, and a structured approach to mechanical licensing exam preparation.

This book rental package provides the three listed technical references in highlighted and tabbed format, helping candidates begin preparation with an organized set of materials.

Reference navigation is especially important for an open-book exam. Candidates can practice moving between the International Mechanical Code, Modern Refrigeration and Air Conditioning, and OSHA safety material while reviewing questions from the major exam categories.

Trade-focused study should concentrate heavily on refrigerants, electrical controls, and refrigeration equipment while still covering piping, system operation, troubleshooting, and safety. A balanced plan can help candidates avoid overlooking smaller content areas that still contribute to the final exam score.

Practice-oriented preparation can help identify weaker topics. Candidates who need additional work with electrical controls can focus on motors, circuits, meters, relays, and controls. Candidates who need more refrigeration theory review can spend additional time on refrigerants, system pressures, temperatures, and the refrigeration cycle.

The goal is to combine organized reference materials with consistent trade review and repeated open-book practice. This helps candidates become more familiar with both refrigeration concepts and the references available during the Oklahoma Refrigeration Journeyman examination.
