Becoming a licensed HVACR journeyman in Maryland involves demonstrating knowledge developed through professional training and hands-on experience. Technicians must understand how heating and cooling systems operate, how equipment is installed, and how mechanical requirements apply to different residential and commercial applications.
This online practice resource supports preparation alongside five important technical references: International Mechanical Code, 2018; Modern Refrigeration and Air Conditioning, 22nd Edition; Residential Load Calculation - Manual J, 8th Edition; Code of Federal Regulations - 29 CFR Part 1926 (OSHA); and the ACCA Ductulator.
Whether you are completing your apprenticeship or reviewing years of practical HVACR experience, online practice questions provide a structured way to reinforce technical knowledge, identify subjects requiring additional attention, and develop effective examination preparation habits.
Three months of access gives you time to approach preparation systematically. Begin with essential HVACR principles, strengthen your understanding of specialized subjects, and revisit challenging material before your examination.
Practice-oriented studying encourages active learning by helping you evaluate technical questions and apply knowledge rather than relying entirely on reading reference publications.

The examination evaluates technical knowledge involving electrical systems, piping, refrigeration, air conditioning, heating equipment, air distribution, and workplace safety.
The official PSI examination outline identifies six major subject areas:
Refrigeration and Air Conditioning represents the largest examination category, with 25 questions. Electrical Knowledge and Heating Systems each account for 20 questions.
These three categories represent 65% of the examination. Understanding their relative importance can help you allocate your study time while maintaining familiarity with all six examination subjects.
With four hours available for 100 questions, candidates have an average of 2.4 minutes per question. Efficient technical reasoning and reference navigation are important elements of examination preparation.
The Maryland HVACR Journeyman (PSI) examination is an open book test. Candidates may bring approved reference publications into the examination room according to PSI's testing rules.
Approved references include the 2018 International Mechanical Code, Modern Refrigeration and Air Conditioning in the 21st or 22nd Edition, Manual J Residential Load Calculation in the specified eighth edition, OSHA construction safety regulations, and the ACCA Ductulator.
PSI permits reference books to contain highlighting, underlining, and approved indexing tabs. Books must not contain handwritten notes or additional loose or attached papers. Study guides are not permitted in the examination room.
The examination provider does not supply the approved references at the testing center.
Effective open-book preparation includes:
Open-book examinations reward candidates who understand the material and can locate relevant information efficiently. Knowing which reference addresses a particular subject can help reduce unnecessary searching.
Use online practice sessions to develop familiarity with the topics and technical publications before examination day.
Maryland HVACR licensing is administered through the state's Board of Heating, Ventilation, Air Conditioning and Refrigeration Contractors.
The licensing process establishes qualifications for individuals performing HVACR work under the direction and control of appropriately licensed contractors.
Completing the apprenticeship requirements and organizing documentation before applying for examination authorization helps create a more manageable path toward journeyman licensing.
The Maryland Board of Heating, Ventilation, Air Conditioning and Refrigeration Contractors regulates HVACR licensing throughout the state.
Maryland establishes specific qualifications for the Journeyman HVACR license, including apprenticeship experience and successful completion of the licensing examination.
The established requirements include:
Maryland law also provides for recognition of certain comparable professional training, formal education, teaching experience, and qualifying work experience when accepted by the Board.
A Journeyman HVACR license allows the license holder to provide HVACR services within the scope established by state law and under the applicable direction and control of a licensed contractor.
Understanding these requirements helps candidates organize their professional development and prepare for the responsibilities associated with journeyman-level HVACR work.
The following references support preparation for the Maryland PSI HVACR Journeyman examination.
These references complement one another by addressing mechanical codes, HVACR technical theory, residential load calculations, workplace safety, and air distribution design.
Using the references alongside online practice questions encourages a broader understanding of the subjects included in the Maryland HVACR Journeyman examination.
The Maryland HVACR Journeyman (PSI) - Online Practice Questions resource supports preparation across the six major examination categories.
Electrical systems are essential to the operation of heating, ventilation, air conditioning, and refrigeration equipment.
Review alternating-current and direct-current principles, motors, relays, contactors, thermostats, protective devices, and equipment control circuits.
Understanding the relationship between electrical controls and mechanical operation can help you interpret questions involving HVACR equipment.
Refrigeration and Air Conditioning represents 25 questions, making it the largest examination subject area.
Study refrigeration cycles, compressors, condensers, evaporators, refrigerants, metering devices, equipment sizing, and system operation.
Review installation principles, common troubleshooting concepts, and maintenance practices associated with air conditioning and refrigeration systems.
Piping knowledge is important for HVACR equipment installation and service.
Review piping materials, joints, fittings, supports, valves, insulation, testing, and schematic interpretation.
Understanding how piping components support equipment operation helps connect mechanical installation requirements with practical applications.
Heating Systems accounts for 20 examination questions.
Study heating principles, equipment types, combustion air, fuel oil systems, hydronic systems, vents, chimneys, and equipment operation.
Review system sizing, installation, maintenance, and troubleshooting concepts to strengthen your understanding of different heating applications.
Air Distribution Systems represents 15 examination questions and includes both technical installation and system design concepts.
Study duct dimensions, airflow, duct materials, insulation, fittings, ventilation requirements, and testing and balancing principles.
Become familiar with the ACCA Ductulator and its application to duct sizing and airflow relationships.
Residential load calculations help determine heating and cooling requirements based on building characteristics and design conditions.
Review the principles presented in Manual J, including heat gain, heat loss, insulation, windows, infiltration, and building orientation.
Understanding load calculations helps connect equipment selection with the actual heating and cooling needs of a building.
Safety accounts for five examination questions and addresses important principles associated with construction and HVACR work.
Review personal protective equipment, ladder safety, scaffolding, fall protection, tools, material handling, and other subjects covered by OSHA's construction safety regulations.
