Test Information and Study Materials

Students preparing for the North Carolina Heating Group 3 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, residential code review, laws and rules review, residential and commercial load calculation review, 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, and procedural 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, pressure-related terminology, installation requirements, 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, 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 efficiency-related provisions, insulation awareness, duct and system performance awareness, controls, equipment efficiency coordination, definitions, and energy code navigation. Energy code questions may focus on performance, conservation, and efficiency rather than installation alone.

The North Carolina Residential Code, 2018 Edition should be studied for dwelling-related heating and mechanical coordination. Students should review residential system organization, equipment location awareness, building service topics, definitions, tables, exceptions, and code navigation. Residential code questions may describe a dwelling condition and require students to locate the correct section before answering.

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 J - Residential Load Calcs, reprinted 2016, Eighth Full Edition should be studied for residential heating and cooling load concepts. Students should review heat loss, heat gain, design conditions, building envelope factors, orientation, infiltration awareness, internal loads, room-by-room load concepts, and HVAC sizing 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.

Manual D, 2016, 3rd Ed and Manual Q - Commercial Low Pressure, Low Velocity Duct System Design (1990) should be reviewed for duct design. Manual D supports residential duct design, while Manual Q supports commercial low-pressure, low-velocity duct system design. Students should study airflow, friction rate, available static pressure concepts, fittings, equivalent length awareness, supply and return distribution, pressure losses, and duct layout concepts.

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.

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 3 Technician exam uses code, law, 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.
