Test Information and Study Materials

Students preparing for the North Carolina Heating Group 2 Technician exam should use the live virtual training, self-study structure, and listed references together. The preparation process should include administration code review, fuel gas code review, mechanical code review, energy conservation code review, laws and rules review, commercial systems review, small commercial load calculation review, commercial duct design review, refrigeration and air conditioning review, Ductulator practice, calculation review, table navigation, definition review, and repeated reference-navigation practice.

The North Carolina Administration Code and Policies, 2018 Edition should be studied for administrative and procedural topics. Students should review code administration, permits, inspections, approvals, responsibilities, policy language, procedural requirements, and administrative organization. Administrative questions may focus on the process that supports code compliance rather than the technical design of a heating or cooling system.

The North Carolina Fuel Gas Code, 2018 Edition should be studied for gas piping, gas appliances, combustion air awareness, venting awareness, fuel gas definitions, sizing concepts, installation requirements, pressure-related terminology, exceptions, and code navigation. Fuel gas questions may require students to identify whether the issue involves piping, appliances, combustion air, venting, pressure, sizing, or code-defined terminology.

The North Carolina Mechanical Code, 2018 Edition should be studied for heating equipment, mechanical system installation, ventilation, exhaust, appliance coordination, equipment access, mechanical rooms, safety provisions, definitions, tables, exceptions, and mechanical code navigation. Mechanical code questions may describe equipment, a system location, a ventilation condition, or an installation requirement and require students to locate the correct section.

The North Carolina Energy Conservation Code, 2018 Edition should be reviewed for energy efficiency and system performance topics. Students should study code organization, efficiency-related provisions, insulation awareness, duct and system performance awareness, controls, equipment efficiency coordination, and definitions. Energy code questions may focus on performance, conservation, and efficiency rather than installation alone.

NC Board's Laws & Rules - 2026 Edition should be studied for board law and rule language. Students should review technician responsibilities, regulated activities, compliance expectations, application-related rules, disciplinary language, definitions, board procedures, and rule organization. Laws and rules questions often depend on exact wording, so students should practice locating the correct section and reading it carefully.

Manual CS - Commercial Apps., Systems & Equip. (1993) should be studied for commercial HVAC applications, system types, equipment, operating concepts, components, design awareness, and commercial HVAC terminology. Students should use this reference to strengthen understanding of commercial heating and cooling systems, system selection concepts, equipment function, and commercial application awareness.

Manual N - Commercial Load Calculation for Small Commercial Buildings, 5th Edition should be studied for small commercial heating and cooling load concepts. Students should review commercial building envelope factors, internal loads, ventilation loads, occupancy-related considerations, equipment loads, design conditions, and calculation process awareness. This reference helps students connect commercial building conditions to heating and cooling load preparation.

Manual Q - Commercial Low Pressure, Low Velocity Duct System Design (1990) should be reviewed for commercial duct design. Students should study airflow, friction rate, pressure losses, fittings, duct layout concepts, supply and return distribution, low-pressure duct systems, low-velocity design concepts, and commercial air distribution requirements. Duct design questions may require students to understand how airflow, duct size, velocity, and friction rate relate to one another.

The Ductulator should be used during study to practice duct sizing relationships. Students should become comfortable using the tool to compare airflow, duct size, velocity, and friction rate. Ductulator practice can help students connect duct design theory to practical air distribution questions.

Modern Refrigeration and Air Conditioning, 22nd edition should be studied for HVAC fundamentals. Students should review refrigeration cycle operation, compressors, condensers, evaporators, metering devices, controls, motors, air conditioning systems, heating systems, service practices, troubleshooting concepts, safety awareness, and system terminology. Technical trade questions may require students to identify components, understand system operation, or connect symptoms to HVAC principles.

Airflow topics should receive steady review. Students should understand how airflow affects comfort, equipment performance, duct design, static pressure, filtration, balancing, ventilation, exhaust, supply distribution, return air, and system operation. Airflow questions may require reference navigation, Ductulator practice, or general duct design awareness.

Commercial heating and cooling system topics should be reviewed as a separate study area. Students should study how commercial equipment is applied, how air distribution supports system performance, how ventilation and exhaust requirements interact with mechanical systems, and how energy conservation requirements may affect design or installation decisions. Commercial questions may require students to combine code knowledge with system awareness.

Tables, definitions, examples, notes, and exceptions should be studied carefully. Code questions may require students to use definitions and section headings. Load calculation and duct design questions may require students to understand examples, tables, or calculation steps. Refrigeration questions may depend on technical terminology. Laws and rules questions may require exact language.

Reference navigation should be part of every study session. Students should practice using tables of contents, indexes where available, chapter headings, section titles, definitions, tables, examples, calculation steps, rule sections, and code sections. Because the North Carolina Heating Group 2 Technician exam uses code, law, commercial systems, load calculation, duct design, refrigeration, and sizing tool references, students should become comfortable switching between references quickly and accurately.

Live virtual training helps students follow an organized review path, while self-study gives students time to return to the references, reinforce topics, and practice locating information. Students should use each live training session as a guide for what to review next, then use self-study time to work through the references in more detail.

A strong study routine should include mixed review across all listed references. Students can begin with code topics, then move into board laws and rules, commercial systems, Manual N commercial load calculations, Manual Q commercial duct design, Ductulator practice, and Modern Refrigeration and Air Conditioning fundamentals. Mixed review helps students identify whether a question is testing code, law, load calculations, duct sizing, commercial applications, refrigeration fundamentals, airflow, tables, definitions, calculations, or reference navigation.

Students should also practice reading each question carefully. North Carolina Heating Group 2 Technician exam questions may include details about fuel gas, mechanical equipment, energy conservation, commercial systems, permits, inspections, laws and rules, load calculations, duct sizing, airflow, refrigeration components, air conditioning principles, controls, safety, tables, definitions, calculations, or field workmanship. Careful reading helps students select the correct reference before searching for the answer.
