Exam Details

The Tennessee CMC-C classification is the HVAC/Refrigeration Contractor classification. The classification covers work associated with heating, ventilation, air conditioning, refrigeration, HVAC-related gas piping, and associated mechanical systems.

The current Prov CMC-C examination contains 100 questions with 2 hours allowed for completion. Because candidates must work through a substantial number of questions within the available testing time, preparation should focus on both technical understanding and efficient use of reference materials.

The current examination outline includes General Knowledge, Code Requirements, Fuel Gas Systems, OSHA Safety, HVAC Controls, Electrical Concepts, Piping, Load Calculations, HVAC Equipment, Refrigerants and Oils, Air Distribution and Venting, and Fire and Smoke Protection.

Air Distribution and Venting represents a significant portion of the current exam outline. Piping, Fuel Gas Systems, HVAC Equipment, Refrigerants and Oils, and General Knowledge also account for important portions of the examination.

The variety of subjects means candidates should avoid focusing exclusively on one HVAC textbook or one area of field experience. A contractor who is comfortable with equipment installation may still need additional preparation involving codes, refrigerants, piping, controls, calculations, OSHA requirements, or reference navigation.

Live Virtual instruction helps organize these topics into a structured preparation environment, while Self Study Training gives you additional opportunities to review areas that require more attention.

Open Book Test

The Tennessee CMC-C Mechanical HVAC / Refrigeration Contractor exam is an open-book test. Prov currently delivers Tennessee contractor examinations in an open-book format.

Open-book testing does not eliminate the need to study. Mechanical codes, HVAC textbooks, refrigeration references, and federal safety regulations can contain hundreds of pages of technical information. Candidates who are unfamiliar with their references may spend too much examination time looking for answers.

Reference-navigation practice should therefore be part of your study routine. Begin by identifying what a question is testing. Determine whether the subject relates primarily to mechanical codes, refrigeration, HVAC equipment, piping, controls, safety, air distribution, or another technical area. Then choose the reference most likely to contain the supporting information.

The International Mechanical Code should become familiar for mechanical-code subjects. Refrigeration and HVAC textbooks can support questions involving systems, equipment, refrigerants, controls, service practices, and technical principles. OSHA 29 CFR Part 1926 is the primary safety-focused reference among the materials listed for this training.

Practice using indexes, tables of contents, chapter headings, definitions, charts, and tables. The goal is not to memorize every page. Instead, develop enough familiarity with the books that you know where to begin when a technical question appears.

Prov permits authorized references during testing and encourages candidates to prepare reference materials before the exam according to its current testing rules. Candidates should follow the reference-material requirements applicable on their examination date.

Licensing Steps

The CMC-C trade examination is one part of the Tennessee contractor licensing process. The Tennessee Board for Licensing Contractors regulates contractor licensing, while Prov currently administers Tennessee contractor examinations.

1. Determine that CMC-C is the appropriate classification. CMC-C applies to HVAC/Refrigeration contracting and associated mechanical work covered by the classification.
2. Prepare for the applicable examinations. Tennessee contractor applicants pursuing a tested classification complete the applicable trade examination as well as the Tennessee Business and Law examination requirement.
3. Use Live Virtual and Self Study Training. Review the technical subjects represented on the CMC-C exam while becoming familiar with the applicable references.
4. Register for the examination. Follow current Prov registration and scheduling procedures for the Tennessee CMC-C contractor exam.
5. Complete the required examinations. Follow the current identification, testing, security, and open-book reference requirements.
6. Complete the contractor application. Provide the business, qualifying-agent, financial, ownership, and supporting information required for the Tennessee contractor application.
7. Complete remaining licensing requirements. Passing the examinations is one part of licensing. The Tennessee Board for Licensing Contractors determines whether all requirements have been satisfied before a license is issued.

Preparing for the exam while organizing the contractor application can help keep the overall licensing process moving. Candidates should maintain accurate information throughout their application and examination registration.

State Requirements

The Tennessee Board for Licensing Contractors regulates contractor licensing in Tennessee. A contractor license is generally required before bidding or contracting on projects of $25,000 or more, and mechanical and HVAC subcontractors are also subject to contractor licensing requirements when their portion of a project reaches the applicable state threshold.

The CMC-C classification applies specifically to HVAC/Refrigeration contracting. Candidates pursuing this classification complete the trade examination required for CMC-C as part of the contractor licensing process.

Tennessee contractor applicants are also required to satisfy the Tennessee Business and Law examination requirement. The trade exam and Business and Law exam address different areas, so candidates should organize preparation for each accordingly.

The licensing process also includes qualifying-agent information. The qualifying agent is the person associated with satisfying applicable examination requirements for the contracting entity.

Financial information is another component of Tennessee contractor licensing. The Board considers financial information as part of the licensing process and assignment of the applicable monetary limit.

Passing the CMC-C examination does not automatically issue a contractor license. Applicants must complete the remaining licensing requirements before the Tennessee Board for Licensing Contractors approves and issues the applicable license.
