MD-JHVACR Cheat Sheet 2026: One-Page Review of Must-Know Facts

Exam Snapshot: Fees, Format, and Scoring

Before you touch a study guide, get the mechanics locked in your head. The Maryland Journeyman HVACR License Exam (MD-JHVACR) is administered by PSI Services LLC on behalf of the Maryland Board of Heating, Ventilation, Air Conditioning and Refrigeration Contractors. This is the full HVACR Journeyman examination - not the Journeyman Restricted version - so every domain listed on the blueprint is in play for you.

The numbers that matter for planning your test day:

• Format: 100 multiple-choice questions, computer-administered, open-book
• Time limit: 240 minutes
• Passing standard: 70%
• Exam fee: $150 per attempt
• Journeyman-license fee: $25 under the Board schedule effective July 1, 2025

For a deeper breakdown of exactly how the 70% threshold translates into a raw question count, see the MD-JHVACR Passing Score 2026 guide. If you're still weighing whether this exam is worth the time investment relative to your career goals, the ROI analysis walks through that decision in more detail.

The Six Domains at a Glance

The blueprint, sourced from the Board-linked PSI bulletin updated September 1, 2024, breaks the 100 scored items into six domains. Memorize this order and these weights - they tell you exactly where to spend your study hours.

Refrigeration and Air Conditioning is the largest single domain at 25 items, followed closely by Electrical Knowledge, Motors, and Controls and Heating Systems at 20 each. Piping and Air Distribution Systems each carry 15, and Safety, while smallest at 5, still requires precision since every point counts toward your 70% target.

For a full walkthrough of every topic inside each of the six areas - not just the summary here - read the MD-JHVACR Exam Domains 2026 guide, which goes item-by-item through what each domain actually tests.

Eligibility and Application Mechanics

Current eligibility, drawn from Board requirements and Business Regulation section 9A-302, requires all of the following:

• An active Maryland HVACR apprentice license
• At least four years as a licensed apprentice
• 6,000 hours of supervised training during that apprenticeship period

These requirements are subject to applicable Board-approved credit or exemption routes, so if your path involved partial credit or a different training structure, confirm your specific status directly with the Board before assuming standard timelines apply. Notably, graduates of an approved Maryland Apprenticeship and Training Council program who apply for licensure within two years of graduation qualify for the journeyman exam-waiver route - worth checking if you fit that window.

You apply through PSI with documented eligibility, and application approval is required before you can schedule your seat. Don't skip this sequencing: scheduling before approval simply isn't possible, so build the approval timeline into your target test date planning. The full requirement list, including documentation specifics, is covered in the MD-JHVACR Requirements 2026 guide.

Approved References and What You Can Bring

Because this is an open-book exam, your reference materials are part of your strategy, not just a backup. The approved list includes:

• IMC 2012
• Modern Refrigeration and Air Conditioning (19th, 20th, or 21st edition)
• ACCA Manual J, 2006 eighth edition
• The listed OSHA 29 CFR 1926 reference
• ACCA Ductulator

Advance highlighting and permanent tabs are permitted, which means you should tab your references before test day, not during it. Handwritten reference notes, loose papers, and study guides are prohibited - bring only the approved texts in their permitted condition. A silent, nonprogrammable calculator without an alphabetic keyboard is allowed, so check your calculator model in advance rather than discovering a problem at check-in.

If you're still assembling your reference set, the MD-JHVACR Certification Cost 2026 breakdown covers what these approved texts typically add to your total prep budget beyond the $150 exam fee and $25 license fee.

Retake Rules if You Don't Pass

Current Board retake guidance is straightforward but strict on timing: you must wait 30 days before reapplying after a first failure, and 60 days for any subsequent retake request. That means a single miss costs you at least a month of momentum, and a second miss costs two. Plan your first attempt as though it's your only shot - because the retake clock is unforgiving if you treat it as a free practice round.

If you're trying to gauge realistically how difficult this exam is likely to feel given your background, the difficulty guide breaks down what tends to trip up candidates across the six domains. And if you want data-driven context on outcomes rather than assumptions, the pass rate analysis is the place to check.

A Domain-Weighted Study Timeline

Rather than studying every domain equally, allocate time proportional to item weight. Here's a four-week structure built around the actual blueprint:

This is the only place in this cheat sheet where general study mechanics show up, and it's tied directly to the domain weights above - not a generic template. For a more detailed week-by-week plan with specific resource recommendations, see the MD-JHVACR Study Guide 2026. You can also run full-length timed sets on our practice test platform to simulate the 240-minute open-book format before your actual appointment.

What the License Lets You Do

Passing the exam and paying the $25 journeyman-license fee gets you licensed, but journeyman services in Maryland remain under the direction and control of an appropriately licensed contractor. In practical terms, your journeyman license authorizes hands-on installation, service, and repair work on HVACR systems, but the contracting relationship and legal responsibility sit with the licensed contractor you work under.

This structure shapes who actually hires journeymen: HVACR contracting firms, mechanical contractors, and facilities operations that employ licensed contractors bringing journeymen onto crews. If you're mapping out what comes after the exam, the MD-JHVACR Jobs overview and the MD-JHVACR Salary Guide 2026 both address what the license opens up in terms of employment paths, without relying on numbers that aren't part of the official record.

Renewal and Reciprocity

Once licensed, you're on a two-year renewal term, and the Board requires no continuing-education credits to renew - a detail that surprises candidates coming from fields with mandatory CE hours. That said, staying current on code updates and equipment changes is still smart practice, even without a formal requirement.

If you're relocating or working across state lines, Delaware and Virginia reciprocity requires an equivalent active license, qualifying experience, and Board approval. Reciprocity isn't automatic - plan for a documentation and approval process rather than a simple transfer.
