This exam book package brings together the listed materials used to study commercial and residential heating systems, load calculations, duct design, fuel-gas requirements, energy conservation, boiler regulations, code administration, and contractor responsibilities.\u003c\/p\u003e\n\u003cp\u003eThe Heating Group 1 Class I examination covers a broad range of heating knowledge. Candidates may need to work through questions involving warm-air heating systems, hydronic systems, steam systems, fuel-burning equipment, boilers, ventilation, combustion air, fuel-gas piping, equipment selection, heating-load calculations, duct sizing, energy-efficiency requirements, residential installations, commercial applications, and North Carolina licensing rules.\u003c\/p\u003e\n\u003cp\u003eThis package supports preparation by placing the major code and technical references in one organized collection. The North Carolina codes establish enforceable requirements for mechanical systems, fuel gas, energy conservation, residential construction, permits, inspections, and code administration. The ACCA manuals provide recognized methods for residential and commercial load calculations, equipment applications, and duct-system design. The Uniform Boiler and Pressure Vessel Act supports review of regulated boiler and pressure-vessel work, while the ductulator provides a practical tool for airflow and duct-sizing exercises.\u003c\/p\u003e\n\u003cp\u003eHeating Group 1 Class I candidates should prepare for both technical questions and contractor-level responsibilities. Technical knowledge helps candidates evaluate equipment, calculate loads, size ducts, interpret code requirements, and recognize safe installation practices. Contractor preparation also involves understanding the laws and rules governing licensure, supervision, professional conduct, and the permitted scope of work.\u003c\/p\u003e\n\u003cp\u003eThe examination is open book, but the number and variety of references make preparation essential. Candidates should know which book applies to each subject, how its chapters are arranged, and where major tables, formulas, definitions, exceptions, and design procedures are located. Repeated navigation practice can make the reference library more useful during the examination and reduce time spent searching through the wrong publication.\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 CS – Commercial Applications, Systems \u0026amp; Equipment (1993)\u003c\/strong\u003e\u003c\/li\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\u003eUniform Boiler and Pressure Vessel Act\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 1 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 and business portions serve different purposes: the technical examination evaluates trade knowledge, while the business examination addresses contractor-level management and legal responsibilities.\u003c\/p\u003e\n\u003cp\u003eHeating Group 1 covers heating systems associated with water-based and related heating work, including systems commonly described as hydronic, steam, and hot-water heating. Class I is the broader license class and applies to commercial, residential, industrial, and institutional buildings within the authorized classification. Candidates should understand the distinction between Class I and Class II before submitting an examination application.\u003c\/p\u003e\n\u003cp\u003eThe books in this package support preparation for code interpretation, system design, load calculations, equipment selection, combustion requirements, fuel-gas provisions, energy conservation, boiler regulation, duct sizing, and residential and commercial installations. Questions may require candidates to locate a specific code section, apply a calculation procedure, interpret a table, identify an installation limitation, or select the appropriate method for a field condition.\u003c\/p\u003e\n\u003cp\u003eSome examination questions may also depend on practical trade knowledge and field experience rather than language found word-for-word in a reference. Candidates benefit from understanding how system components work together, why a requirement exists, and how installation conditions affect equipment performance and safety.\u003c\/p\u003e\n\u003ch2 style=\"color: #d32f2f;\"\u003eOpen Book Test\u003c\/h2\u003e\n\u003cp\u003eThe North Carolina Heating Group 1 Class I Contractor examination is an open-book test. Candidates are responsible for bringing the approved references assigned to their examination category. Only books and materials permitted by the Board’s current examination rules may be taken into the testing room.\u003c\/p\u003e\n\u003cp\u003eApproved references must be in an acceptable original published format. Hardbound, spiral-bound, ring-bound, and qualifying original loose-leaf code books may be permitted. Printed PDF copies are not accepted as substitutes for approved published references. Candidates should inspect every book before test day and remove any unauthorized papers, inserts, notes, or homemade dividers.\u003c\/p\u003e\n\u003cp\u003eCommercially available, permanently attached index tabs may be used when they comply with the examination policy.

Load-calculation questions may point to Manual J or Manual N. Residential duct-design questions may require Manual D, while commercial low-pressure duct questions may require Manual Q. Equipment-application questions may lead to Manual CS. Code-compliance questions may require the Mechanical, Fuel Gas, Residential, Energy Conservation, or Administration reference.\u003c\/p\u003e\n\u003cp\u003eRead complete code sections before choosing an answer. A requirement may be affected by an exception, table note, definition, limitation, or cross-reference.
