The North Carolina Administration Code and Policies, 2018 Edition should be studied for administrative and procedural topics, including code administration, permits, inspections, approvals, responsibilities, policy language, and procedural organization. The North Carolina Fuel Gas Code, 2018 Edition should be studied for fuel gas piping, gas appliances, combustion air, venting, definitions, sizing concepts, pressure-related terminology, installation requirements, and exceptions. 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, and mechanical code navigation.

The North Carolina Energy Conservation Code, 2018 Edition should be reviewed for efficiency-related provisions, insulation awareness, duct and system performance awareness, controls, equipment efficiency coordination, definitions, and energy code navigation. The North Carolina Residential Code, 2018 Edition should be studied for dwelling-related heating and mechanical coordination, equipment location awareness, building service topics, definitions, tables, exceptions, and residential code navigation.

NC Board's Laws & Rules - 2026 Edition should be studied for board law and rule language, contractor responsibilities, regulated activities, compliance expectations, application-related rules, disciplinary language, definitions, board procedures, and rule organization. NASCLA Business, Law, and Project Management 7th Edition should be studied for contractor business operations, contracts, estimating, bidding, project management, scheduling, financial management, labor topics, safety, risk management, insurance topics, and legal responsibilities.

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

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 mechanical code, business law, residential code, or duct design. Boiler-related topics should be reviewed carefully because act language can be different from technical HVAC textbook 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, business sections, act language, and code sections. Because the North Carolina Heating Group 1, Class I 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 so students can identify whether a question is testing code, fuel gas, mechanical systems, energy conservation, laws and rules, business law, commercial applications, residential load calculations, commercial load calculations, duct sizing, boiler topics, airflow, tables, definitions, calculations, or reference navigation.
