The Master HVAC Tradesman is Virginia’s top individual tradesman license in the HVAC specialty — the level defined by planning, layout, and supervision, and the license the Board requires behind every licensed HVAC contractor firm. Master candidates sit the same shared 85-item portion as journeyman candidates, at a passing score of 64 stated as a raw count. The PassProfessor program prepares candidates for that standing and sitting; its companion guide is at /virginia-master-hvac-tradesman-exam-guide/.

A credential defined by planning and supervision
The regulation at 18VAC50-30-10 draws the line between Virginia’s individual HVAC levels in functional words. A journeyman installs, repairs, and maintains, with working knowledge sufficient to comply with the pertinent provisions of the Uniform Statewide Building Code and to work according to plans and specifications. A master is a person able to plan and lay out details for installation and supervise the work of installing, repairing, and maintaining, with the same USBC working knowledge. The Master credential is therefore not a longer-service version of the journeyman credential. It certifies a different function: the tradesman who designs the layout others execute, and who answers for the work as a whole.
That functional definition explains everything else in this page. It explains why the Master gates are measured in years held and years practised rather than in training hours. It explains why the Master license, alone among the individual levels, carries a firm-side qualification function. And it explains why the examination does not change its form at this level: planning judgment is examined on the same body of trade and regulatory material the journeyman faces, held to a higher passing score and reached through a higher gate.
The standing a Master carries for a firm
Virginia licenses contracting firms separately from individuals, under a distinct system of Class A, B, and C contractor licenses issued to business entities. For the HVAC classification, the connection between the two systems runs through the Master license. The Code provides that the Board shall require a master tradesman license as a condition of licensure for heating, ventilation, and air conditioning contractors, among other trades. For the HVAC classification specifically, the firm’s Qualified Individual must hold a Master HVAC tradesman license issued by the Board for Contractors — and the Board-approved examination column for that classification reads as no separate examination: there is no separate Qualified Individual specialty examination for HVAC. Department guidance states the same rule directly: the Qualified Individual must hold a current Master tradesman card in the appropriate classification.
The consequence deserves emphasis, because it is the commercial heart of this credential: the Master HVAC tradesman examination itself is the Qualified Individual’s entire examination burden for the firm’s HVAC classification, and a Master licensee is the person on whom a firm’s ability to hold the classification rests. That standing does not make the Master license a contractor license — the firm must still hold its own Class A, B, or C license, whose Designated Employee separately passes the class business portions belonging to the contractor track, not to this credential. Within the individual system, no other license unlocks what this one unlocks.
What a Master may not do
The limits are the framework’s limits, and they bind the top level exactly as they bind the others. A Master tradesman may not practise in a classification or specialty for which they are not licensed — one of the prohibited acts listed at 18VAC50-30-190. Failure to comply with the USBC is likewise prohibited, as is failure to obtain a building permit or an applicable inspection where required, and the full list of nineteen prohibited acts — material noncompliance, misrepresentation, aiding or abetting an unlicensed contractor or allowing one’s license to be used by an unlicensed individual, among them — applies without discount for seniority. And the Master license, being an individual tradesman license, does not itself license a firm to contract: firms contract on firm licenses. A candidate who describes the Master credential as a contractor license misunderstands both systems at once. Since July 1, 1995, no individual may engage or offer to engage as a tradesman unless licensed under Article 3, and practising except as provided there constitutes a Class 1 misdemeanor — the planning and supervisory function this credential certifies is exercised from inside the license, never outside it.
The three gates to the Master examination
Master eligibility is set at 18VAC50-30-39, in the Master table, and it is experience-only. There is no vocational-training-hours column in the Master table, and no training-hours route to this examination should be constructed from the tables that govern other levels. A candidate qualifies through any one of three routes: having held a valid Residential HVAC license in the desired trade for 3 years; having held a valid journeyman license in the desired trade for a minimum of 1 year; or 9 years of practical experience in the desired trade. Each route certifies the same underlying proposition in a different currency — time inside the Virginia system at the level below, time inside the residential pathway, or long direct practice in the trade.
The general applicant requirements apply identically at this level: the applicant must be at least 18 years old, document identification, vocational training, and experience, comply with the Board’s examination-conduct rules, provide an address of record, and disclose any felony or non-marijuana misdemeanor conviction in any jurisdiction and any action by any licensing body in any jurisdiction. Experience is verified by reference letters from building officials, building inspectors, current or former employers, contractors, engineers, architects, or current or past clients, and education by transcript or diploma copy. An incomplete application process lapses after 12 months. One caution is load-bearing: older material quoting the regulation’s repealed predecessor states a longer direct-experience route to this level. The current table governs, and its direct route is 9 years; any document offering a different figure for the Master gate is working from a closed rule.
No exemption from the Master examination is stated in the sources this package is built from. The sourced exemption — for completers of an approved apprenticeship program — exempts candidates from the journeyman examination only, and it does not reach this level. Out-of-state recognition operates at level: an out-of-state master holder may sit for the Virginia Master examination with an application and a copy of the current license, and substantially equivalent licensure obtained through a substantially equivalent examination is recognised. Neither route lowers the gate; both preserve it.
The examination, briefly: a shared portion at a higher score
Master candidates do not sit a separate, harder examination form, and preparation built on that assumption wastes effort. The Board approves all applications for testing first — candidates must have completed all Board education and experience requirements before applying for the examination — and approved candidates then sit, through PSI under its Individual License and Certification Candidate Information Bulletin, copyright 2026, dated July 23, 2026, the same shared Journeyman/Master HVAC portion that journeyman candidates sit: 85 items, 210 minutes, open book, the same content outline including its ten-item regulatory block keyed to 18VAC50-30, and the same reference list. The Master distinction on examination day is the passing score: 64 on the 85-item portion, a raw count of correct answers exactly as the bulletin publishes it, and the distinct PSI examination fee for this level, addressed below.
The sitting rules are the bulletin’s general tradesman rules: candidates bring their own references, none are provided, and no study guides are permitted; references may be highlighted, underlined, and indexed beforehand but must contain no writing, writing during the session is prohibited on pain of confiscation and a report to the Department, and only permanent tabs are allowed. One to ten experimental items may be administered besides the scored items; they will not be scored, however they will count against examination time. Scheduling, cancellation, identification, calculator, scoring, and retest rules follow the bulletin as the companion guide works them at full length; examination fees are not refundable or transferable and remain valid one year from payment.
Tested code, adopted code, and one open reference question
Code questions on this portion are keyed to the International Mechanical Code, 2021 edition, in its national edition, supported by Modern Refrigeration and Air Conditioning, 22nd edition, and the tradesman regulations themselves. No Virginia code volume, no USBC volume, no fuel gas code, and no National Electrical Code appears on the reference list for this portion, and Virginia amendments do not change examination answers. The adopted layer is separate: field work is governed by the Uniform Statewide Building Code, 2021 edition, effective January 18, 2024, which incorporates the 2021 model codes including the 2021 International Mechanical Code as referenced. Tested and adopted remain distinct bodies of law even where the mechanical code year matches, and a Master — whose function includes layout decisions others will build from — is the licensee least able to afford confusing them.
The same open reference question recorded for the shared portion applies here identically. The bulletin prints NFPA 31, the Standard for the Installation of Oil-Burning Equipment, 2011 edition, inside the block headed for HVAC references, while the parenthetical tags attached to entries in that block name a different trade. Whether NFPA 31 is an allowed or required reference for this portion is unresolved in the sources, and this page does not resolve it in either direction. Confirm with PSI or DPOR before relying on it.
Fees, stated by instrument and never merged
The examination fee for the Master HVAC examination is $125, paid to PSI — the Master level’s own vendor figure, distinct from the journeyman level’s. The Board’s license fees under 18VAC50-30-90 are a separate instrument: an original license by examination is $150, a license without examination $150, a card exchange $110, and an additional tradesman designation $105, all nonrefundable, not prorated, and active one year from receipt. The regulation separately states a ceiling on the Board’s examination charge for a master examination; that ceiling is a cap in the rule, not a fee charged to any candidate, and it is not presented here as one. The two live instruments — PSI’s examination fee and the Board’s license fee — are printed side by side and never combined into a single total, because no such total is published by either party.
Holding the Master license
The Master license runs on the same tradesman clock as every designation under the chapter: valid for three years from issuance, with HVAC licenses expiring three years from the last day of the month in which they were issued. Renewal costs $160 and requires 3 hours of Board-approved continuing education for the HVAC designation, relating to applicable building code changes in the International Mechanical Code, as a condition of renewal or reinstatement. Holding both journeyman and master designations in the same trade does not double the hours owed for that trade. Failure to receive a renewal notice does not relieve the duty to renew, and the Board’s date of receipt, not the postmark, decides renewal against reinstatement.
If renewal is not completed within 30 days of expiration, reinstatement is required at $210, which includes the $160 renewal fee, available up to 24 months after expiration, keeping the same license number and continuous standing; beyond 24 months the individual applies again under current requirements and will be deemed eligible to sit for the examination for the same category and specialty. Practising on an expired license may be treated as unlicensed activity, and there is no inactive or retired status. For a Master licensee who anchors a firm’s HVAC classification, these dates are not personal administration: a lapsed Master card puts the firm’s Qualified Individual position in question, and the renewal clock deserves the same planning discipline the credential itself certifies.
What the PassProfessor program will cover
The level’s own substance first. This program is built Master-led: the planning, layout, and supervision function the regulation defines; the three experience-only gates at 18VAC50-30-39 and how each is documented; the firm-qualifying standing the license carries and the boundary that keeps it distinct from a contractor license; and the renewal exposure that standing creates. The shared examination is then prepared as what it is — the full 85-item published outline, regulatory block included, worked to the higher raw passing score this level must reach, with the open-book method the sitting enforces.
Accuracy at the joints. The program teaches the current Master table and names its repealed predecessor as closed, keeps the tested national IMC 2021 and the adopted USBC 2021 in their separate layers, states every fee by its instrument, and presents the NFPA 31 reference question as open rather than settled in either direction.
Independence, stated plainly. PassProfessor is an independent preparation provider, not affiliated with DPOR, the Board for Contractors, or PSI, and this program is not a Virginia course. Completing it confers no license and no standing; the Board alone licenses tradesmen, and candidates apply and test through the Board and PSI channels described above. The gates, standing, and sitting are worked in full in the companion guide at /virginia-master-hvac-tradesman-exam-guide/.

Frequently asked questions
What makes the Master level different from the Journeyman level?
Function. The regulation defines the Master as able to plan and lay out details for installation and supervise the work of installing, repairing, and maintaining — the level that designs and answers for the whole job.
What are the routes to the Master examination?
Three experience-only routes under 18VAC50-30-39: a valid Residential HVAC license held for 3 years, a valid journeyman license held for a minimum of 1 year, or 9 years of practical experience in the trade. The Master table states no training-hours route.
Is there a separate Master examination?
No. Master candidates sit the same shared Journeyman/Master HVAC portion as journeyman candidates — 85 items, 210 minutes, open book — at the Master passing score.
What score passes at Master level?
A passing score of 64 on the 85-item portion — a raw count of correct answers, exactly as the PSI bulletin publishes it.
Does the Master license let a firm contract for HVAC work?
It qualifies the individual to serve as the Qualified Individual behind a firm’s HVAC classification — the Board requires a master tradesman license as a condition of licensure for HVAC contractors, and no separate Qualified Individual specialty examination applies. The firm itself still contracts on its own Class A, B, or C contractor license; the Master license alone is not a contractor license.
What does the Master examination cost?
The PSI examination fee at this level is $125, paid to PSI. The Board’s original license fee by examination is $150, a separate instrument. This package does not merge the two.
How long does the Master license last, and what renews it?
Three years. Renewal costs $160 with 3 hours of Board-approved code-change continuing education for the HVAC designation. Holding journeyman and master designations in the same trade does not double the hours for that trade.
Is PassProfessor affiliated with DPOR or PSI?
No. PassProfessor is an independent preparation provider. The Board alone licenses tradesmen, and PSI administers the examination under contract with DPOR.
