This exam book package brings together the listed materials used to study forced-air heating and cooling systems, residential and commercial load calculations, low-pressure duct design, refrigeration principles, fuel-gas requirements, energy conservation, code administration, and contractor responsibilities.\u003c\/p\u003e\n\u003cp\u003eHeating Group 3 Class I covers forced-air heating and cooling systems with a cooling capacity of 15 tons or less in residential, commercial, and industrial buildings. Candidates preparing for this classification need a broad understanding of furnaces, heat pumps, air-conditioning equipment, refrigeration cycles, electrical controls, air distribution, ventilation, fuel-fired appliances, system sizing, equipment installation, and applicable North Carolina requirements.\u003c\/p\u003e\n\u003cp\u003eThis package supports preparation for both code-based and technical questions. The North Carolina Administration Code and Policies addresses permits, inspections, approvals, enforcement, and construction-code administration. The North Carolina Fuel Gas Code covers fuel piping, appliance connections, combustion air, venting, regulators, shutoff valves, and system testing. The North Carolina Mechanical Code addresses heating, cooling, ventilation, refrigeration, duct systems, equipment locations, installation requirements, and mechanical safety.\u003c\/p\u003e\n\u003cp\u003eThe North Carolina Energy Conservation Code supports study of equipment efficiency, HVAC controls, duct sealing, insulation, piping requirements, system performance, and other energy-related provisions. The North Carolina Residential Code provides requirements affecting heating, cooling, mechanical, and fuel-gas installations in one- and two-family dwellings and townhouses within its scope. The NC Board’s Laws \u0026amp; Rules addresses contractor classifications, applications, examinations, supervision, professional conduct, and licensing responsibilities.\u003c\/p\u003e\n\u003cp\u003eThe HVAC design references add practical calculation and system-design material. Manual J supports residential load calculations, while Manual N addresses load calculations for small commercial buildings. Manual D covers residential duct-system design, and Manual Q addresses commercial low-pressure, low-velocity duct systems. Modern Refrigeration and Air Conditioning provides broad technical coverage of refrigeration, heating, air conditioning, electrical controls, equipment, installation, service, and troubleshooting. The ductulator supports practical airflow and duct-sizing exercises.\u003c\/p\u003e\n\u003cp\u003eBecause the examination is open book, candidates should learn how each reference is organized before test day. Effective preparation requires more than carrying the books into the examination room. Candidates should understand the trade, know which publication applies to each subject, and practice locating definitions, tables, formulas, exceptions, and code sections efficiently.\u003c\/p\u003e\n\u003ch2 style=\"color: #d32f2f;\"\u003eWhat You Get\u003c\/h2\u003e\n\u003cdiv style=\"border: 3px solid #d32f2f; padding: 20px; margin: 25px 0; background-color: #fff7f7;\"\u003e\n\u003ch3\u003eNorth Carolina Code \u0026amp; Regulatory References\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eNorth Carolina Administration Code and Policies, 2018 Edition\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eNorth Carolina Fuel Gas Code, 2018 Edition\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eNorth Carolina Mechanical Code, 2018 Edition\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eNorth Carolina Energy Conservation Code, 2018 Edition\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eNorth Carolina Residential Code, 2018 Edition\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eNC Board’s Laws \u0026amp; Rules – 2026 Edition\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eHVAC Design \u0026amp; Technical References\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eManual J – Residential Load Calculations, 2016 Reprint, 8th Full Edition\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eManual N – Commercial Load Calculation for Small Commercial Buildings, 5th Edition\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eManual Q – Commercial Low Pressure, Low Velocity Duct System Design (1990)\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eManual D – Residential Duct Systems, 2016, 3rd Edition\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eModern Refrigeration and Air Conditioning, 22nd Edition\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eDuctulator\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003ch2 style=\"color: #d32f2f;\"\u003eExam Details\u003c\/h2\u003e\n\u003cp\u003eThe North Carolina Heating Group 3 Class I Contractor examination is administered under the authority of the North Carolina State Board of Examiners of Plumbing, Heating, and Fire Sprinkler Contractors.

Contractor applicants must also satisfy the applicable Business and Law examination requirement unless they qualify for an exemption recognized by the Board. The technical examination focuses on trade knowledge and code application, while the Business and Law portion addresses contractor-level administrative, legal, and business responsibilities.\u003c\/p\u003e\n\u003cp\u003eHeating Group 3 Class I applies to forced-air heating and cooling systems with a mechanical refrigeration capacity of 15 tons or less in residential, commercial, and industrial buildings.

Modern Refrigeration and Air Conditioning supports refrigeration theory, electrical systems, HVAC equipment, service procedures, and troubleshooting.\u003c\/p\u003e\n\u003cp\u003eHeating and cooling candidates are expected to provide a ductulator. Practice using it to compare airflow, friction rate, velocity, and round or rectangular duct dimensions.
