Whether you are completing an HVACR apprenticeship, gaining professional ventilation experience, or reviewing technical knowledge before the licensing examination, online practice questions offer an organized way to reinforce important concepts and develop confidence in your preparation.
With a focused emphasis on duct systems, ventilation design principles, and installation safety, this resource helps you prepare for the specific knowledge areas associated with the Maryland PSI Journeyman Restricted Ventilation examination.
Three months of access gives you time to approach preparation systematically. Begin with ventilation fundamentals, concentrate on duct design and installation subjects, and revisit challenging topics before your examination date.
Practice-oriented preparation encourages you to apply your technical knowledge instead of relying exclusively on reading code books and construction standards.
The Maryland Journeyman Restricted Ventilation examination is administered by PSI Services LLC through the licensing examination program overseen by the Maryland Board of Heating, Ventilation, Air Conditioning and Refrigeration Contractors.
The examination evaluates knowledge of air distribution systems and construction safety. Its content focuses on ventilation installations, duct sizing, duct assembly, materials, supports, insulation, mechanical system requirements, and safe working practices.
The PSI content outline identifies two major examination categories:
Air Distribution Systems accounts for 35 of the 40 examination questions, representing 87.5% of the test. Safety accounts for the remaining 12.5%.
This distribution makes ductwork and ventilation knowledge the primary study priority. Candidates should concentrate on practical air distribution concepts while maintaining familiarity with OSHA construction safety requirements.
With 90 minutes available for 40 questions, candidates have an average of approximately 2.25 minutes per question. Efficient reference navigation and familiarity with ventilation terminology can help you manage your examination time effectively.
The Maryland Journeyman Restricted Ventilation (PSI) examination is an open book test. Candidates may bring designated technical references into the examination room according to PSI testing rules.
The examination permits approved mechanical code publications, duct construction standards, ventilation calculation references, HVACR technical books, and construction safety regulations.
PSI permits approved reference materials containing highlighting, underlining, and acceptable indexing tabs. Reference books must not contain handwritten notes, loose papers, attached materials, or inserted study guides.
The examination provider does not supply these reference materials at the testing center.
Effective open-book preparation includes:
Open-book examinations require more than locating individual answers. Candidates benefit from understanding the subject being tested and recognizing which reference contains the relevant information.
Regular practice can help strengthen your familiarity with technical requirements and reduce time spent searching through reference materials.
Maryland HVACR licensing is regulated by the Board of Heating, Ventilation, Air Conditioning and Refrigeration Contractors.
The Restricted Ventilation classification is intended for individuals performing specialized ventilation work under the direction and control of an appropriately licensed HVACR contractor.
Maryland also provides a licensing pathway for graduates of qualifying apprenticeship programs approved by the Maryland Apprenticeship and Training Council. Applicants meeting that pathway's requirements may qualify for journeyman restricted licensing without taking the examination.
Organizing apprenticeship records and training documentation can help simplify your preparation for the examination and subsequent licensing application.
The Maryland Board of Heating, Ventilation, Air Conditioning and Refrigeration Contractors regulates restricted journeyman licensing for specialized HVACR services, including ventilation.
Under Maryland's statutory qualification pathway, applicants for a Journeyman Restricted license must satisfy the following requirements:
Maryland law also allows the Board to consider comparable formal education, professional training, and certain qualifying work experience under established provisions.
A Maryland Journeyman Restricted Ventilation license authorizes work within the designated ventilation specialty while under the direction and control of an appropriately licensed HVACR contractor.
The credential recognizes specialized training and technical understanding in ventilation systems, mechanical installations, and related safety practices.
The following six references support preparation for the Maryland PSI Journeyman Restricted Ventilation examination and are identified among its approved examination materials.
The references complement one another by addressing mechanical installation codes, HVACR technical principles, fibrous glass duct construction, metal and flexible duct construction, airflow calculations, and workplace safety.
Using these materials during preparation helps develop familiarity with the technical publications associated with ventilation work and the PSI examination.
