Mississippi HVAC Contractor Ultimate Exam Prep Rental Package

Prepare for the Mississippi HVAC contractor licensing exams with a complete rental package that combines the approved reference materials, organized exam preparation, and application support in one structured solution. The Mississippi HVAC Contractor Ultimate Exam Prep Rental Package is designed for experienced heating, ventilation, and air-conditioning professionals who are ready to pursue a Mississippi contractor license and want a practical way to prepare for both the HVAC trade exam and the required Mississippi Law and Business Management exam.

This package eliminates the need to locate the listed exam books individually. It includes a comprehensive rental set covering HVAC systems, refrigeration, load calculations, duct design, mechanical codes, fuel-gas requirements, LP-gas requirements, construction safety, and Mississippi contractor business law. The books are highlighted and permanently tabbed to help you move through important sections more efficiently while studying and during the open-book examinations.

Open-book contractor exams still require strong preparation.

The course and organized book set help you build those skills through trade-focused review, reference navigation, and practice-oriented preparation.

The package also includes Application Service and one full year of course access. This gives you an organized framework for working through the study materials while receiving support with the Mississippi contractor application process. The goal is to help you approach the exams and licensing requirements with a clear plan, properly organized materials, and greater confidence in your preparation.

Exam Details

The Mississippi HVAC contractor licensing process generally requires the qualifying party to pass the HVAC trade examination and the Mississippi Law and Business Management examination. The Mississippi State Board of Contractors must receive and review the contractor application before the applicant can schedule the required exams. After eligibility is approved, the applicant’s information is sent to PSI, the testing provider.

The Mississippi HVAC examination covers all aspects of heating and cooling work, including fuel-gas systems, appliances, associated equipment, and ductwork. The exam contains 80 questions, allows four hours, and requires a score of 70 percent to pass.

HVAC exam subjects include piping, insulation, hangers and supports, sound and vibration control, heating and cooling principles, refrigerants, refrigeration systems, load calculations, testing and balancing, controls, air-conditioning equipment, heat pumps, furnaces, heaters, chimneys, flues, vents, combustion air, fuel-gas systems, LP-gas systems, ductwork, boilers, hydronic systems, machine rooms, evaporative cooling, and safety.

The Mississippi Law and Business Management exam is mandatory for applicants seeking commercial or residential contractor licenses. It contains 50 questions, allows two hours, and requires a score of 70 percent to pass.

Law and Business Management topics include licensing, estimating, bidding, lien law, financial management, tax laws, labor laws, project management, contracts, business organization, risk management, environmental requirements, and safety. Preparation for this exam should include learning how the Mississippi NASCLA guide is organized and practicing how to locate business-law answers quickly.

The examinations may also include a small number of unscored experimental questions. These questions are used for future exam development and count toward the total testing time, even though they do not affect the candidate’s final score.

Open Book Test

The Mississippi HVAC and Law and Business Management contractor examinations are open book. Candidates are responsible for bringing the permitted reference materials to the testing center. The books included in this rental package are selected to support preparation for the listed HVAC and business-law examination content.

Reference books may be highlighted, underlined, and indexed before the examination. Permanent tabs are permitted, while temporary tabs such as removable notes or Post-it-style markers are not permitted. Candidates may not add loose papers or unauthorized inserts to the books, and writing in the references during the examination is prohibited.

The included rental books are highlighted and permanently tabbed to help you identify key chapters, formulas, tables, definitions, and code provisions. These features can reduce the time required to find important material, but candidates should practice with the books before test day. Knowing what each reference contains is as important as knowing where the tabs are located.

A useful open-book strategy is to identify the main keywords in each question before opening a reference. Decide whether the question relates to refrigeration, mechanical code, fuel gas, LP gas, duct construction, safety, load calculations, business law, or another subject. Then select the most likely book and use its index or table of contents to locate the answer.

Licensing Steps

1. Choose the correct contractor classification. Confirm that the Mississippi HVAC classification matches the work the company intends to perform.
2. Establish the applicant’s business information. The contractor application must accurately identify the individual or business entity seeking the license.
3. Select the qualifying party. The qualifying party is the person responsible for taking the required examinations and demonstrating the knowledge and experience needed for the classification.
4. Complete the Mississippi contractor application. Prepare the required application forms and supporting documentation for submission to the Mississippi State Board of Contractors.
5. Submit the application for review. The Board reviews the filing and notifies the applicant of missing requirements or examination eligibility.
6. Receive testing authorization. Once eligibility is sent to PSI, the candidate receives instructions for registering and scheduling the examinations.
7. Prepare for the exams. Study the trade and business-law subjects, learn the reference materials, and complete timed book-navigation practice.
8. Take the required examinations. Bring acceptable identification and only the books and materials permitted by the current testing rules.
9. Complete any remaining requirements. Provide outstanding documents or corrections requested during the application review.
10. Receive Board review. Passing the exams does not automatically issue a license. The completed application remains subject to final approval by the Mississippi State Board of Contractors.

State Requirements

The Mississippi State Board of Contractors regulates contractor licensing for the applicable HVAC classification. The state’s HVAC specialty classification covers the installation, maintenance, repair, fabrication, alteration, and extension of heating, ventilation, and air-conditioning systems. The classification also includes associated HVAC equipment, ductwork, duct cleaning, industrial air systems for dust control, ventilation systems, and related work.

All applicants must complete the Mississippi Law and Business Management examination. The HVAC trade examination is also required unless the Board approves a qualifying trade-exam waiver through an applicable reciprocity provision.

The qualifying party must be associated with the applicant as an owner, officer, executive staff member, or responsible managing employee. The qualifying party must have the experience, knowledge, and ability to supervise or perform work within the requested HVAC classification.

Commercial contractor applications may require a reviewed or audited financial statement prepared and signed by a certified public accountant. Commercial applicants may also need to provide general liability insurance, business references, workers’ compensation coverage when applicable, and proof that the business entity is in good standing.

Forming a company or passing an examination does not independently authorize HVAC contracting work. The applicant must satisfy the complete licensing process and receive approval before representing the business as licensed for work that falls under Mississippi contractor licensing requirements.

Exam Room Approved Books

The included rental set contains the references identified for the Mississippi HVAC trade exam and the Mississippi Law and Business Management exam. Candidates should bring the applicable books for each scheduled examination and follow the current PSI Candidate Information Bulletin regarding permitted editions and testing-center rules.

The books may be highlighted, underlined, and indexed before testing. Permanent tabs are allowed. Temporary tabs, loose papers, handwritten inserts, and removable notes are not allowed. Code questions are based on the specific code editions listed for the examination, making it important to use the designated editions when answering code-related questions.

The 22nd edition of Modern Refrigeration and Air Conditioning is included in this package. This is especially important because earlier listed editions are no longer used for the applicable examination beginning August 1, 2026.

Test Information and Study Materials

Begin your preparation by learning the purpose of every book in the rental set. The International Mechanical Code and International Fuel Gas Code are likely choices for code-based installation questions. NFPA 58 applies to LP-gas subjects. The OSHA reference addresses construction safety. Manual J and Manual N focus on load calculations, while Manual D and the Ductulator support duct-system design and airflow calculations.

Use Modern Refrigeration and Air Conditioning for broad technical review involving refrigeration, heating, cooling, equipment, controls, and system principles. Use the NASCLA Mississippi guide for licensing, contracts, bidding, financial management, project management, taxes, labor, risk, and business organization.

Create timed lookup drills using the highlighted and tabbed references. Select a topic, locate the correct book, search the index, and find the applicable section. Record how long the process takes and repeat difficult searches until the navigation becomes familiar.

Calculation practice should be completed with the same tools and references you expect to use during the exam. Review load calculations, airflow, duct sizing, piping relationships, and other trade mathematics. Work through each calculation carefully and check units before selecting an answer.
