Exam Details

Mechanical Work is a major contractor classification recognized by the Mississippi State Board of Contractors. The classification involves heating, cooling, refrigeration, associated equipment, piping, ductwork, plumbing work, and related mechanical systems.

The scope can include the installation, maintenance, repair, fabrication, alteration, or extension of central air-conditioning, refrigeration, heating, and ventilation systems. Mechanical work may also involve duct systems, plumbing installations, process piping, boiler-related systems, equipment piping, and other work that falls within the approved classification.

The Mississippi Mechanical contractor trade examination is administered by PSI after the Mississippi State Board of Contractors reviews the applicant’s filing and provides examination eligibility. Candidates cannot schedule the examination until the licensing application has been submitted and PSI receives authorization from the Board.

The Mechanical examination is broad because it covers several systems rather than one limited trade. Candidates should prepare for topics involving refrigeration, HVAC equipment, heating and cooling principles, mechanical code, plumbing code, fuel-gas systems, LP-gas systems, duct construction, airflow, commercial load calculations, residential duct design, piping, sprinkler-system requirements, and safety.

Questions may require direct trade knowledge, code interpretation, table navigation, reference lookup, or calculations. A candidate may need to identify the correct installation requirement, select an appropriate material, locate a code exception, interpret a technical table, or apply information from one of the listed manuals.

Modern Refrigeration and Air Conditioning supports broad review of heating, cooling, refrigeration cycles, refrigerants, equipment, controls, components, troubleshooting concepts, installation practices, and system operation. The International Mechanical Code supports mechanical-system questions involving equipment, ventilation, exhaust, ducts, combustion air, chimneys, vents, and related installations.

The International Plumbing Code supports preparation involving fixtures, water distribution, sanitary drainage, traps, vents, piping materials, testing, and plumbing installations. The International Fuel Gas Code addresses fuel-gas piping, equipment connections, appliances, combustion air, testing, and venting. NFPA 58 supports preparation involving liquefied petroleum gas containers, piping, storage, handling, equipment, and safety.

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

NFPA 13 addresses automatic sprinkler-system installation concepts, system components, piping arrangements, spacing, water supplies, and related provisions. The Pipefitter’s Handbook provides practical piping information, formulas, fitting dimensions, layout methods, and field calculations. The OSHA reference supports preparation involving federal construction-safety requirements.

Mississippi contractor applicants must also complete the Mississippi Law and Business Management examination. The business and law reference is separate from this trade-only package.

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 concerning approved editions, markings, indexing, tabs, notes, and additional materials.

Open-book testing does not eliminate the need for preparation. The Mechanical examination involves a large reference set, and searching the wrong code or manual can consume valuable testing time. Candidates should know the purpose of every book and practice selecting the correct reference before beginning a lookup.

A mechanical-equipment, ventilation, exhaust, combustion-air, or duct-system question may lead to the International Mechanical Code. A plumbing fixture, water-distribution, drainage, trap, or venting question may require the International Plumbing Code. A fuel-gas piping or appliance question may involve the International Fuel Gas Code, while an LP-gas question may require NFPA 58.

Questions involving refrigeration principles, refrigerants, controls, heating equipment, cooling equipment, or HVAC system operation may be addressed in Modern Refrigeration and Air Conditioning. Duct-fabrication questions may require the HVAC duct construction standard. Commercial load calculations may involve Manual N, while residential duct-design questions may involve Manual D or the Ductulator.

Sprinkler-system questions may lead to NFPA 13. Piping calculations, fitting information, dimensions, and layout questions may involve the Pipefitter’s Handbook. Construction-safety questions may require 29 CFR Part 1926.

Candidates should practice using related index terms because the wording in an exam question may differ from the terminology used in a reference. A question about equipment venting, for example, may require searching under chimneys, flues, combustion air, appliances, or vent connectors.

Code questions are based on the editions identified for the examination. Candidates should review the current PSI Candidate Information Bulletin before testing and confirm the permitted reference editions. Only materials that comply with the current exam-center rules may be brought into the testing room.

State Requirements

The Mississippi State Board of Contractors administers the contractor licensing process. Mechanical Work is a major classification that includes multiple mechanical systems and areas of work.

Applicants should select the classification that accurately reflects the services the business intends to perform. The Mechanical classification is broader than the HVAC specialty classification and can include plumbing, piping, refrigeration, fuel systems, ductwork, and other mechanical work within the approved scope.

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.

The application may require business-registration records, ownership information, qualifying-party documentation, project experience, references, insurance information, and financial records. Information should be complete and consistent across the application and supporting documents.

The Mississippi Law and Business Management examination is required for contractor applicants. The Mechanical trade examination is also required unless the Board approves an applicable trade-examination waiver.

Trade-examination credit or reciprocity does not automatically create a Mississippi contractor license. The applicant must still complete the Mississippi application, 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, utilities, environmental work, or other specialized services. Contractors may also be responsible for local permits, inspections, registrations, insurance, and project-specific approvals.
