Exam Details

The Mississippi Ductwork for Heating, A/C and Ventilation Contractor examination is administered through PSI as part of the Mississippi contractor licensing process. The examination contains 60 questions. Candidates receive 2 hours to complete the test and must earn a minimum passing score of 70%, which equals 42 correct answers.

The examination content outline includes:

• Ducts: 39 questions
• Hoods and Ventilation Equipment and Devices: 6 questions
• General Knowledge: 10 questions
• Safety: 5 questions

Ducts represent 39 of the 60 examination questions, making this the dominant subject area. Candidates should devote substantial preparation time to duct construction, fabrication, installation, fittings, supports, materials, sizing concepts, and related mechanical-code requirements.

General Knowledge represents another 10 questions. This portion can draw on practical sheet metal and ductwork knowledge, mechanical construction concepts, tools, terminology, installation procedures, and industry practices.

Hoods and Ventilation Equipment and Devices accounts for six questions. Candidates should prepare for commercial ventilation concepts and requirements involving hoods, exhaust systems, duct construction, and fire-protection considerations. NFPA 96 and the International Mechanical Code are important references for this subject.

Safety accounts for five questions and requires familiarity with OSHA construction requirements applicable to ductwork installation and related jobsite operations.

With 120 minutes available for 60 questions, candidates have an average of approximately two minutes per question. Efficient use of the reference materials can therefore be an important part of exam preparation.

Open Book Test

The Mississippi Ductwork for Heating, A/C and Ventilation examination is an open-book test. Candidates are responsible for bringing the permitted reference materials to the examination center.

The approved references may be highlighted, underlined, and indexed before the examination session. Permanent tabs may be used. Temporary tabs such as Post-it notes are not permitted, and additional loose or attached papers are not allowed with the approved references.

An open-book exam still requires preparation. Candidates have only two hours to complete 60 questions, so spending several minutes searching through the wrong reference can quickly affect testing pace.

A duct-construction question may lead directly to HVAC Duct Construction Standards, Metal and Flexible. A sheet metal fabrication or trade-practice question may be addressed in Sheet Metal. Questions involving mechanical-code requirements may require the 2021 International Mechanical Code.

Commercial kitchen exhaust, ventilation control, grease ducts, hoods, or related fire-protection questions may require NFPA 96. Jobsite safety questions may require 29 CFR Part 1926. Airflow and duct-sizing questions may involve the Ductulator.

Practice identifying the subject before searching. Determine whether the question is primarily about duct construction, mechanical code, sheet metal, commercial kitchen ventilation, safety, or airflow sizing. Then select the reference most likely to contain the answer.

Repeated navigation practice can help candidates become familiar with indexes, tables of contents, chapter arrangements, code sections, diagrams, tables, and technical terminology. The goal is to develop a consistent open-book workflow before examination day.

State Requirements

The Mississippi State Board of Contractors identifies Ductwork for Heating, A/C and Ventilation as a test-required specialty classification within its mechanical classifications.

The scope of the classification is unlimited ductwork for heating, air conditioning, and ventilation systems. This specialty classification is more focused than Mississippi's broader Mechanical and HVAC classifications, which can cover additional equipment, piping, refrigeration, controls, and other mechanical work.

Applicants should select the classification that accurately corresponds with the services the business intends to perform. The State determines which examinations an applicant is qualified and required to take based on the license application and classification requested.

The qualifying party must satisfy the examination requirements associated with the company application.

Test Information and Study Materials

A focused Mississippi Ductwork for Heating, A/C and Ventilation study plan should reflect the examination distribution. Because Ducts account for 39 questions, most preparation time should be devoted to duct construction and installation.

Ducts preparation should include duct materials, fabrication, fittings, joints, seams, reinforcement, supports, hangers, connections, flexible duct, pressure relationships, airflow, sizing, installation, and applicable mechanical-code requirements. HVAC Duct Construction Standards is a central reference for this category.

Hoods and Ventilation Equipment and Devices accounts for six questions. Review commercial exhaust systems, hoods, ventilation equipment, grease ducts, installation requirements, clearances, and fire-protection concepts. The International Mechanical Code and NFPA 96 are important resources for this portion of the test.

General Knowledge accounts for 10 questions. Study sheet metal terminology, fabrication techniques, tools, measurements, installation methods, airflow concepts, and practical field knowledge. Candidates should connect technical rules with the way duct systems are actually constructed and installed.

Safety represents five questions. Review OSHA requirements applicable to construction work, including personal protective equipment, ladders, scaffolding, fall hazards, tools, electrical hazards, materials handling, and general jobsite safety.

The Ductulator should be used during preparation rather than treated as an unfamiliar tool on examination day. Practice reading airflow, friction rate, velocity, and duct-size relationships until basic navigation becomes comfortable.

Timed reference drills can help candidates prepare for the two-hour examination. Read a practice question, identify the main keyword or subject, select the most appropriate reference, and locate supporting information within a limited amount of time.

Because the test averages approximately two minutes per question, candidates should avoid spending too long on a single difficult lookup. Build enough familiarity with the books that common topics can be located efficiently.

Mixed-topic study can also be useful. Move between duct construction, sheet metal, mechanical-code questions, NFPA 96, safety, and Ductulator exercises so that switching between references becomes a normal part of preparation.
