Prepare for the Virginia Refrigeration Contractor examination with a professionally highlighted and tabbed reference package designed to make studying and open-book navigation more efficient. The Virginia Refrigeration Contractor Exam Highlighted & Tabbed Book Package includes the technical refrigeration and mechanical code references used to support preparation for the Virginia Refrigeration Contracting specialty examination.
This package includes Modern Refrigeration and Air Conditioning, 22nd Edition and the International Mechanical Code, 2021 Edition. The books are highlighted and permanently tabbed for exam preparation, helping candidates identify important sections and move through the references more efficiently during study sessions and open-book testing.
Virginia identifies Refrigeration Contracting by the specialty abbreviation REF. The specialty covers the installation, repair, or removal of refrigeration equipment, excluding HVAC equipment. The scope is intended for contractors working with refrigeration equipment such as coolers, refrigerated casework, ice-making machines, drinking fountains, cold-room equipment, and similar hermetic refrigeration equipment.
The REF specialty does not include electrical, plumbing, gas-fitting, or HVAC functions. Candidates preparing for this specialty should understand the defined scope because examination preparation should remain focused on refrigeration systems, equipment, piping, refrigerants, controls, testing, inspection, and the applicable mechanical code provisions.
Because the Virginia Refrigeration Contracting examination is open book, candidates benefit from learning how to use their references efficiently. Bringing books into the examination room does not eliminate the need to study. Candidates still need to understand refrigeration principles and recognize where technical and code information can be found. Highlighted sections and permanent tabs give candidates an organized starting point for building those reference-navigation skills.
This package is well suited for refrigeration technicians, service professionals, installers, business owners, supervisors, and Qualified Individuals preparing for the Virginia REF specialty examination. It can also serve as a useful technical reference set for professionals who want organized access to refrigeration and mechanical code material after completing their exam preparation.
Please allow up to 15 business days for tabbed and highlighted book package orders.
The highlighting and tabbing service is designed to reduce the amount of book preparation candidates need to complete before beginning their exam study. Highlighting draws attention to selected material, while permanent tabs create visual navigation points throughout the references. Candidates should still review every tab, learn the organization of each book, and practice locating information before examination day.
The Virginia Refrigeration Contracting examination is a contractor specialty examination for the Qualified Individual associated with the REF specialty. Virginia uses PSI as the examination vendor for contractor specialty examinations, and candidates must satisfy the applicable eligibility and approval requirements before scheduling the examination.
The Virginia Refrigeration Contracting examination contains 50 questions. Candidates receive 120 minutes to complete the examination and must achieve a minimum score of 70%, or 35 correct answers.
The examination content is organized into the following subject areas:
General Knowledge and Requirements represents the largest individual portion of the examination. Refrigeration Systems and Controls is another major area, followed by Refrigeration Piping. These subject areas should receive substantial attention when building a study schedule.
Refrigerants and Testing and Inspection contain fewer questions but remain important. A complete preparation strategy should address every examination category rather than concentrating only on the largest sections.
The examination may include questions based on the listed references as well as questions involving trade knowledge and general industry practices. Practical experience can therefore be valuable, but candidates should also be comfortable with written technical terminology, mechanical code provisions, refrigeration components, system operation, piping concepts, and inspection procedures.
The Virginia Refrigeration Contracting examination is an open-book test. Candidates must bring their own permitted references because books are not supplied at the examination site.
The listed code reference for the examination is the International Mechanical Code, 2021 Edition. For code-based questions, candidates should prepare with the listed edition and become familiar with its organization before test day.
Reference materials may be highlighted, underlined, and indexed before entering the examination. Permanent tabs are permitted. Removable tabs, such as temporary flags and similar repositionable markers, are not allowed.
Reference materials containing writing are not permitted under PSI examination rules, and candidates may not write in reference books during the examination session. Loose papers and unbound references are also not permitted. These rules make properly prepared books especially useful for candidates who want an organized reference system without relying on handwritten notes.
The highlighted and tabbed books in this package are prepared to help candidates move more efficiently between important topics. The International Mechanical Code can be used when a question calls for a specific code requirement, while Modern Refrigeration and Air Conditioning provides broader technical information about refrigeration theory, systems, components, installation, controls, and service principles.
With 50 questions and 120 minutes available, candidates have an average of approximately 2.4 minutes for each question. That makes efficient book use important. A candidate who has studied the tabs, chapter structure, and index beforehand can generally locate material more effectively than someone using unfamiliar references for the first time.
Virginia contractor licensing is administered by the Virginia Board for Contractors through the Department of Professional and Occupational Regulation. Contractor businesses are licensed according to a class and one or more classifications or specialties.
The REF examination is only one part of the overall contractor licensing process. Candidates should prepare for the specialty exam while also making sure the business satisfies the separate requirements associated with its intended contractor license class.
Virginia requires each contractor business to designate a Qualified Individual for every classification or specialty on its license. The Qualified Individual is responsible for meeting the experience and examination qualifications associated with that area of work.
The experience requirement depends on the contractor license class. A Qualified Individual for a Class C contractor must have at least one year of experience in the applicable classification or specialty. Class B requires at least three years of experience, while Class A requires at least five years of experience.
Virginia also requires new contractor license applicants to complete eight hours of Board-approved pre-license education. This business-focused education requirement is separate from technical preparation for the Refrigeration Contracting examination.
The REF specialty is defined specifically around refrigeration work. It covers installation, repair, and removal of refrigeration equipment other than HVAC equipment. Examples include coolers, refrigerated casework, ice-making machines, drinking fountains, cold-room equipment, and similar hermetic refrigeration equipment.
The specialty does not authorize electrical, plumbing, gas-fitting, or HVAC functions. Candidates and contractor businesses should understand this distinction when determining whether the REF specialty matches the work they intend to perform.
The two references serve different but complementary purposes. Modern Refrigeration and Air Conditioning provides broad technical instruction and refrigeration theory, while the International Mechanical Code provides code requirements. Candidates who understand which reference is likely to contain a particular answer can reduce unnecessary searching during the test.
The permanent tabs can help candidates locate major chapters and subject areas quickly. Highlighted material can help draw attention to important concepts during study. The greatest value comes from actively using the prepared books before examination day and becoming familiar with how the tabs and highlighted sections relate to the examination topics.
A practical preparation plan should follow the official examination categories. Begin with General Knowledge and Requirements, which contains 16 questions. Build a solid understanding of refrigeration fundamentals, system operation, components, terminology, installation concepts, and general trade practices.
Next, spend significant time on Refrigeration Systems and Controls. This category contains 12 questions and requires candidates to understand how refrigeration systems operate as complete systems. Review compressors, condensers, evaporators, metering devices, pressure and temperature relationships, system controls, and the interaction between major components.
Refrigeration Piping accounts for 10 questions. Candidates should review piping materials, system arrangements, installation considerations, sizing principles, fittings, connections, and code requirements associated with refrigeration piping. The highlighted International Mechanical Code can help candidates practice locating relevant code provisions, while Modern Refrigeration and Air Conditioning provides broader technical context.
Testing and Inspection accounts for seven questions. Preparation should include system testing concepts, inspection practices, equipment operation, troubleshooting principles, and methods used to confirm proper refrigeration system performance.
Refrigerants represents five questions. Candidates should understand refrigerant characteristics, applications, system relationships, handling concepts, and the role refrigerants play throughout the refrigeration cycle.
Use the highlighting and permanent tabs as study tools rather than relying on them only during the examination. Start by reviewing every tab in both books. Learn what each tab identifies, then review the surrounding pages and chapter content so that the location becomes familiar.
When working through practice questions, first determine the subject category. Then choose the reference most likely to contain the information. Use the permanent tabs, table of contents, index, headings, and highlighted material to locate the answer. Repeating this process helps candidates develop faster reference-navigation habits.
Timed study sessions are particularly helpful. With two hours available for 50 questions, candidates should practice balancing knowledge with book lookups. If a question can be answered confidently from technical knowledge, excessive searching may waste time. If the question asks for a precise code requirement or technical detail, using the reference may be appropriate.
When a practice question is answered incorrectly, avoid simply memorizing the correct choice. Find the supporting section in the book, review the surrounding topic, and understand why the answer is correct. That method develops knowledge that can transfer to other questions phrased differently.
Please allow up to 15 business days for tabbed and highlighted book package orders. Candidates should account for this preparation period when planning their study schedule or selecting an examination date.
1 Exam Prep helps Virginia Refrigeration Contractor candidates create a more organized path to exam preparation. A highlighted and tabbed book package gives candidates prepared references that can be used immediately for technical review and open-book navigation practice.
Trade-focused preparation begins with understanding the major examination areas: General Knowledge and Requirements, Refrigeration Piping, Refrigerants, Refrigeration Systems and Controls, and Testing and Inspection. Organizing study around these categories helps candidates spend their preparation time on subjects directly related to the exam.
Reference navigation is another essential part of preparation. The Virginia REF exam is open book, but limited testing time means candidates need to work efficiently. Permanent tabs make major sections easier to identify, while highlighting helps draw attention to selected material during review.
Practice-oriented preparation helps turn the books into working exam tools. Candidates can repeatedly practice identifying a question's subject, selecting the appropriate reference, locating the relevant tab or chapter, and finding the information needed to answer the question.
1 Exam Prep encourages candidates to combine practical refrigeration experience with organized technical review. A technician may already understand how a system operates in the field but still benefit from reviewing code terminology, reference organization, and written technical concepts used in contractor examinations.
By studying consistently, practicing book navigation, reviewing weaker subject areas, and working with prepared reference materials, candidates can approach the examination with a clearer strategy and stronger familiarity with the technical information they may need to use.
The package includes Modern Refrigeration and Air Conditioning, 22nd Edition and the International Mechanical Code, 2021 Edition. Both books are highlighted and permanently tabbed for exam preparation.
Please allow up to 15 business days for tabbed and highlighted book package orders.
