Exam Details

Mechanical Work is recognized as a major commercial contractor classification by the Mississippi State Board of Contractors. The classification covers mechanical systems and allows the license holder to perform the specialty classifications identified within the Mechanical category, subject to the scope of the license and any separate regulatory requirements.

The Mechanical classification is broader than a single HVAC specialty. Preparation may involve heating, ventilation, air conditioning, refrigeration, plumbing, piping, fuel-gas systems, LP-gas systems, ductwork, load calculations, equipment installation, sprinkler-system concepts, and construction safety.

The Mechanical contractor examination may require candidates to interpret code requirements, use technical tables, identify proper installation methods, complete calculations, and apply practical trade knowledge. Questions may involve direct technical knowledge or require the candidate to locate information within one of the approved references.

Modern Refrigeration and Air Conditioning supports preparation involving refrigeration cycles, refrigerants, heating systems, cooling systems, controls, equipment, troubleshooting concepts, and HVAC operation. The International Mechanical Code addresses mechanical installations, ventilation, exhaust, duct systems, combustion air, chimneys, vents, and related equipment requirements.

The International Plumbing Code supports preparation involving fixtures, water distribution, sanitary drainage, venting, traps, piping, materials, testing, and plumbing-system installation. The International Fuel Gas Code addresses fuel-gas piping, appliance connections, combustion air, venting, testing, and related safety provisions.

NFPA 58 supports questions involving liquefied petroleum gas containers, piping, storage, handling, equipment, and installation. NFPA 13 addresses automatic sprinkler-system installation, system components, piping arrangements, spacing, water supplies, and related provisions.

Manual N supports small-commercial heating and cooling load calculations. Manual D and the Ductulator support residential duct-system design, airflow, velocity, pressure, friction rate, fittings, and duct sizing. The HVAC duct construction standard addresses metal and flexible duct fabrication, reinforcement, support, assembly, and installation.

The Pipefitter’s Handbook provides practical piping information, fitting dimensions, formulas, measurements, layout methods, and field calculations. The OSHA reference supports preparation involving federal construction-safety requirements and workplace practices.

Mississippi contractor applicants must submit the applicable license application before scheduling the required examinations. The Mississippi State Board of Contractors reviews the application and sends the candidate’s eligibility information to PSI after authorization to test is granted.

Mississippi contractor applicants must also prepare for the Mississippi Law and Business Management examination. The NASCLA Mississippi Business and Law reference is not included in this trade-only package and must be obtained separately.

Open Book Test

Mississippi contractor examinations administered through PSI are open book. Candidates are responsible for bringing the permitted references to the testing center and following the current rules for book editions, highlighting, tabs, markings, notes, and supplemental materials.

An open-book examination still requires substantial preparation. A mechanical candidate may need to work with several books during one testing session. Opening the wrong code or searching an unfamiliar index can consume valuable time and make it difficult to complete the examination efficiently.

The books in this package are professionally highlighted and permanently tabbed to support faster navigation. Highlighting identifies important technical information, while tabs divide the references into major chapters and subject areas. Candidates should study the organization before testing rather than relying on the tabs for the first time in the examination room.

Begin each lookup by identifying the main subject of the question. Mechanical equipment, ventilation, exhaust, combustion air, and duct-system questions may lead to the International Mechanical Code. Plumbing fixtures, drainage, venting, and water-distribution questions may require the International Plumbing Code.

Fuel-gas piping and appliance questions may involve the International Fuel Gas Code. LP-gas questions may require NFPA 58. Automatic sprinkler-system questions may lead to NFPA 13. Construction-safety questions may require 29 CFR Part 1926.

Heating, cooling, refrigeration, equipment, and control questions may be addressed in Modern Refrigeration and Air Conditioning. Duct-fabrication and support questions may require the HVAC duct construction standard. Commercial load questions may involve Manual N, while residential duct-design questions may require Manual D or the Ductulator.

Practice using related index terms because an examination question may not use the exact wording found in the book. A question about appliance ventilation may require searching terms such as venting, combustion air, flues, chimneys, or equipment installation.

Candidates should review the current PSI Candidate Information Bulletin before test day. Temporary tabs, removable notes, loose papers, and unauthorized inserts may not be permitted. The testing provider determines whether each reference and its preparation comply with examination-room rules.

Licensing Steps

State Requirements

The Mississippi State Board of Contractors regulates commercial and residential contractor licensing. Mechanical Work is one of the major commercial classifications recognized by the Board.

The Mechanical category includes multiple specialty classifications, such as boiler installation and repair, ductwork for heating and ventilation, fueling systems, HVAC, mechanical insulation, plumbing, process piping, refrigeration, and other mechanical work. Applicants should select the classification that accurately reflects the services the business intends to perform.

The qualifying party must have a relationship with the applicant that is accepted by the Board. Depending on the business structure, the qualifying party may be an owner, officer, executive staff member, or responsible managing employee.

Applicants must provide detailed experience relevant to the requested classification. General office work does not demonstrate the practical construction experience needed to qualify a business for mechanical contracting work.

Commercial applications may require financial documentation, insurance information, business-registration records, ownership details, references, and proof of the qualifying party’s relationship to the applicant. Information should be accurate and consistent across the application and supporting documents.

The Mississippi Law and Business Management examination is required as part of the contractor licensing process. The applicable trade examination may also be required unless the Board approves an examination waiver under an available reciprocity agreement.

Reciprocity does not automatically issue a Mississippi license. Even when trade-exam credit is accepted, the applicant must complete the Mississippi application process, satisfy the remaining requirements, complete required state testing, and receive final approval.

Additional requirements may apply to plumbing, fire-sprinkler systems, fuel gas, LP gas, utility connections, environmental work, and other specialized services. Contractors may also need local permits, registrations, inspections, insurance, or approvals based on the project location and scope.
