Idaho HVAC Specialty Journeyman - Online Practice Questions

Prepare for the Idaho HVAC Specialty Journeyman examination with online practice questions focused on the code knowledge tested by the state. The Idaho HVAC Specialty Journeyman exam is based on the 2018 International Fuel Gas Code (IFGC), with questions covering all seven chapters of the code.

This exam-preparation product is designed for candidates who want a structured way to practice applying fuel-gas code requirements before test day. Rather than relying only on reading and highlighting the code book, practice questions help reinforce how individual requirements are used in realistic exam situations involving gas piping, appliance installation, combustion air, chimneys, vents, equipment, definitions, and general fuel-gas regulations.

The Idaho HVAC Specialty Journeyman examination contains 50 questions and allows 120 minutes. A minimum score of 70 is required to pass. The examination is open book and is administered through PSI for the Idaho Division of Occupational and Professional Licenses.

The exam is entirely based on the 2018 International Fuel Gas Code. The published examination blueprint distributes questions across Chapters 1 through 7, with the greatest emphasis on gas piping installations, chimneys and vents, general regulations, specific appliances, and gaseous hydrogen systems.

Because the exam is open book, candidates need both fuel-gas knowledge and efficient code-navigation skills. Knowing that the answer is somewhere in the IFGC is only the beginning. Candidates should be able to identify the subject of a question, select the correct chapter, locate the applicable section or table, review any exceptions, and apply the requirement within the available testing time.

Online practice questions support that process by giving candidates repeated opportunities to work through the types of subjects identified in the official examination blueprint. Practice can help strengthen familiarity with the structure of the 2018 IFGC while also identifying areas that deserve additional review.

Exam Details

The Idaho HVAC Specialty Journeyman Exam is administered through PSI. The current published examination information identifies the following format:

• Number of Questions: 50
• Time Allowed: 120 minutes
• Minimum Passing Score: 70
• Exam Type: Open book
• Testing Provider: PSI
• Approved Code Reference: International Fuel Gas Code, 2018

The official exam blueprint distributes the 50 questions across the seven chapters of the 2018 International Fuel Gas Code:

Chapter 4, which addresses gas piping installations, represents the largest individual portion of the examination. Chapter 5, covering chimneys and vents, is another major category. Chapters 3, 6, and 7 each contribute a substantial number of questions, so candidates should prepare across the entire code rather than concentrating on only one or two chapters.

With 50 questions in 120 minutes, candidates have an average of approximately 2.4 minutes per question. Efficient use of the code book is therefore an important part of preparation.

Open Book Test

The Idaho HVAC Specialty Journeyman examination is an open book test. The approved examination reference is the 2018 International Fuel Gas Code.

Candidates are responsible for bringing their own approved reference material to the examination center. The current PSI examination rules allow pre-exam highlighting, underlining, and permanent indexing. Writing in the reference during the examination session is prohibited.

Temporary markers such as Post-it-style notes are not permitted. Additional loose papers are also prohibited. Candidates preparing a reference book for test day should organize it before arriving at the examination center and use only permanent indexing that complies with the testing rules.

Open-book testing makes familiarity with the layout of the IFGC extremely useful. Candidates should know which chapters address administration, definitions, general regulations, gas piping, chimneys and vents, specific appliances, and gaseous hydrogen systems.

Practice questions can be used as navigation exercises. Before checking an answer, identify which IFGC chapter most likely controls the issue. Then locate the applicable section, table, or exception. Repeating this process builds familiarity with the book and helps develop a consistent method for approaching code questions under a time limit.

Licensing Steps

Idaho HVAC licensing is administered by the Idaho Division of Occupational and Professional Licenses. The Specialty Journeyman credential has its own experience and qualification requirements.

1. Gain qualifying specialty HVAC experience. Idaho requires a minimum of 2,000 hours of specialty-related experience.
2. Work within the required supervision structure. Specialty HVAC experience must satisfy the requirements governing supervised specialty installation work.
3. Choose the examination pathway. Idaho allows a Specialty Journeyman applicant to qualify by meeting the experience requirement and passing the board-designated examination.
4. Register for the HVAC Specialty Journeyman examination through PSI. Idaho HVAC examinations are currently administered through PSI.
5. Prepare with the 2018 International Fuel Gas Code. The current Specialty Journeyman examination blueprint is based entirely on Chapters 1 through 7 of the IFGC.
6. Complete the 50-question examination. Candidates receive 120 minutes.
7. Achieve the required passing score. A minimum score of 70 is required.
8. Apply for licensure through Idaho DOPL. After satisfying the applicable examination and experience requirements, complete the state licensing process.

Idaho rules also recognize an education pathway for Specialty Journeyman applicants. That pathway requires the specialty-related experience and satisfactory completion of at least 60 hours of education in fuel-gas code and piping installation methods. This product is designed for candidates preparing to satisfy the examination pathway.

State Requirements

Idaho requires an HVAC Specialty Journeyman applicant to document a minimum of 2,000 hours of specialty-related experience.

In addition to the experience requirement, an applicant must either pass the examination designated by the Idaho HVAC Board or complete at least 60 hours of education in fuel-gas code and piping installation methods. Candidates using the examination pathway prepare for the 50-question HVAC Specialty Journeyman test.

The permitted scope of an Idaho HVAC Specialty Journeyman is specific. The credential permits installation of hearth appliances and non-duct-connected oil furnaces, along with the associated fuel-gas piping and venting dedicated exclusively to those installations.

The Specialty Journeyman scope does not include plumbing, electrical, or duct work. Candidates should understand that the specialty credential is narrower than Idaho's full HVAC Journeyman license and does not provide unrestricted authority to perform every type of HVAC installation.

The fuel-gas component of the specialty makes familiarity with the International Fuel Gas Code particularly important. Candidates should understand installation requirements affecting appliance locations, combustion air, gas piping, shutoff valves, regulators, pressure testing, venting, vent connectors, clearances, and other code requirements that can affect hearth appliances and related fuel-gas systems.

Idaho currently uses the 2018 International Fuel Gas Code as one of its adopted HVAC codes. The same edition is identified as the approved reference for the HVAC Specialty Journeyman examination.

Idaho does not currently require continuing education for HVAC license renewal. Specialty Journeyman licenses are issued on a three-year term under the state's HVAC licensing structure.

Test Information and Study Materials

Chapter 1 — Scope and Administration: The examination includes approximately six questions from Chapter 1. Review the scope, applicability, intent, administrative provisions, approvals, permits, inspections, and other foundational requirements contained within the chapter.

Chapter 2 — Definitions: Approximately six questions come from Chapter 2. Definitions can be important because the exact code meaning of a term may determine how another section applies. Practice locating definitions quickly and distinguishing between similar fuel-gas terms.

Chapter 3 — General Regulations: Approximately seven questions are drawn from Chapter 3. Review appliance and equipment location, structural considerations, access, combustion and ventilation air, protection, clearances, and general installation requirements.

Chapter 4 — Gas Piping Installations: With approximately nine questions, Chapter 4 is the largest individual exam category. Study fuel-gas piping materials, sizing, installation, valves, regulators, pressure limitations, testing, purging, appliance connections, sediment traps, and related requirements.

Gas-pipe sizing deserves particular attention. Candidates should practice identifying the correct sizing method and table, determining required inputs, tracing developed piping lengths, and selecting the appropriate pipe size under the stated conditions.

Chapter 5 — Chimneys and Vents: Approximately eight questions come from Chapter 5. Review venting systems, vent connectors, draft hoods, mechanical draft systems, clearances, vent sizing, chimney requirements, termination locations, and prohibited venting arrangements.

Hearth appliances depend heavily on proper venting, making Chapter 5 especially relevant to the practical scope of the Specialty Journeyman license. Candidates should become comfortable navigating both prescriptive text and vent-sizing tables.

Chapter 6 — Specific Appliances: Approximately seven questions are based on Chapter 6. Review requirements for the fuel-gas appliances addressed by the code, including appliance installation, clearances, combustion air relationships, controls, connections, and equipment-specific provisions.

Chapter 7 — Gaseous Hydrogen Systems: Approximately seven questions are drawn from Chapter 7. Do not overlook this chapter simply because gaseous hydrogen work may be less familiar than ordinary natural-gas or propane installations. The published blueprint gives it the same approximate question count as Chapters 3 and 6.

Code Navigation: Practice locating the governing section before reading every nearby provision. Use permanent indexing to organize major chapters and frequently used subjects when preparing the reference for the examination.

Tables and Exceptions: Many fuel-gas questions require more than finding a section heading. Practice reading tables, footnotes, exceptions, limitations, and referenced sections so that the selected answer reflects the entire requirement.

Timed Practice: The official exam allows 120 minutes for 50 questions. Practicing with time limits can help candidates decide when to perform a detailed code lookup and when to move forward and return to a difficult question later.
