Test Information and Study Materials

Students preparing for the North Carolina Heating Group 1, Class II Contractor exam should use the live virtual training, self-study structure, and listed references together. The preparation process should include administration code review, residential code review, laws and rules review, NASCLA business review, commercial applications review, Manual J load calculation review, Manual D duct design review, boiler and pressure vessel review, Ductulator practice, table navigation, definition review, calculation awareness, 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 system.

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, dwelling provisions, definitions, tables, exceptions, and residential 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 contractor 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.

NASCLA Business, Law, and Project Management 7th Edition should be studied for contractor business topics. Students should review business organization, contracts, estimating, bidding, project management, scheduling, financial management, labor topics, safety, risk management, insurance topics, lien awareness, tax-related concepts, and legal responsibilities. Contractor-level questions may require practical judgment and careful reference navigation.

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

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. Load calculation questions may require understanding the purpose of the calculation and how input factors affect the final load.

Manual D, 2016, 3rd Ed should be reviewed for residential duct design. Students should study airflow, friction rate, available static pressure concepts, fittings, equivalent length awareness, supply and return distribution, duct layout concepts, and residential air distribution design. 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.

The Uniform Boiler and Pressure Vessel Act should be studied for boiler and pressure vessel terminology, act language, regulated equipment awareness, inspection-related concepts, legal organization, and safety provisions. Students should practice identifying when a question is testing boiler or pressure vessel act language rather than residential code, business law, or duct design.

Commercial application topics should be reviewed alongside residential topics. Heating Group 1, Class II candidates may need to recognize how commercial systems, equipment types, system applications, and operating concepts differ from residential heating and air distribution work. Students should practice reading each question carefully so they can choose between Manual CS, the residential code, Manual J, Manual D, NASCLA, board rules, or another listed reference.

Airflow and duct design topics should receive steady attention. Students should understand how airflow affects comfort, equipment performance, supply distribution, return air, duct sizing, friction rate, velocity, fittings, pressure losses, and system operation. Airflow questions may require Manual D navigation, Ductulator use, table review, or general duct design awareness.

Tables, definitions, examples, notes, and rule language 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. Boiler questions may depend on act terminology. Business questions may require careful review of project management, contract, safety, financial, or legal concepts.

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, business sections, rule sections, act language, and code sections. Because the North Carolina Heating Group 1, Class II Contractor exam uses code, law, business, commercial applications, load calculation, duct design, boiler, 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 administration code and residential code topics, then move into board laws and rules, NASCLA business topics, Manual CS commercial applications, Manual J residential load calculations, Manual D duct design, Ductulator practice, and The Uniform Boiler and Pressure Vessel Act. Mixed review helps students identify whether a question is testing code, laws and rules, business law, commercial systems, load calculations, duct sizing, boiler topics, airflow, tables, definitions, calculations, or reference navigation.

Students should also practice reading each question carefully. North Carolina Heating Group 1, Class II Contractor exam questions may include details about residential code, permits, inspections, laws and rules, business operations, commercial systems, load calculations, duct sizing, airflow, boilers, pressure vessels, tables, definitions, calculations, or field workmanship. Careful reading helps students select the correct reference before searching for the answer.
