Virginia’s residential HVAC pathway is a standalone tradesman license for work in dwellings and townhouses, examined on its own PSI portion — 55 items in 120 minutes, open book, with a passing score of 39 stated as a raw count. The PassProfessor Virginia Residential HVAC Mechanic program prepares candidates for that license and that sitting, and its companion guide at /virginia-residential-hvac-mechanic-exam-guide/ works through the scope and the route in full.

One credential, two names in the record — stated once, plainly
This program is named Virginia Residential HVAC Mechanic, following the name under which the credential is catalogued. In the regulation itself, at 18VAC50-30-10, the defined term for this same credential is Residential HVAC tradesman, and the PSI bulletin heads its examination portion simply RESIDENTIAL HVAC. All three names denote one credential, one eligibility table, and one examination portion; this page uses the program name for the program and the regulation’s term where the definition is discussed, and neither name is silently substituted for the other. A candidate searching the regulation or the bulletin under any of these names is looking at the same license described below.
What this credential certifies — and where its scope stops
The regulation defines the Residential HVAC tradesman as a person qualified to perform HVAC work with working knowledge of the USBC provisions applicable to dwellings and townhouses — as defined in the Virginia Residential Code — or structures annexed to them. The Virginia Residential Code, for this purpose, means the construction code provisions applicable to the residential occupancy class for such structures, including the International Residential Code as amended by the Board of Housing and Community Development. The definition then draws the credential’s hard line in the same sentence’s second half: it does not include commercial, industrial, institutional, or government-use structures.
That exclusion is the whole scope discipline of this license, and it deserves to be read as a working rule rather than as fine print. A holder may perform HVAC work in the dwelling-and-townhouse universe the definition describes. The moment a structure is a commercial, industrial, institutional, or government-use building, the work is outside this credential — simply outside it — and belongs to licensees whose scope reaches that building. No system-size, tonnage, or fuel-type limit for this credential is stated in the sources, and none is printed here: the boundary the regulation draws is one of building type, and importing a size cap from another state’s residential license would invent a limit Virginia’s definition does not contain.
The framework’s general limits apply identically: no practice in a specialty for which the tradesman is not licensed, USBC compliance, and permit and inspection duties — prohibited-act provisions at 18VAC50-30-190. This is an individual tradesman license under Article 3, issued by the Board for Contractors in DPOR: it is not a firm contractor license. Since July 1, 1995, no individual may engage as a tradesman in Virginia unless licensed under Article 3, and practising except as provided there constitutes a Class 1 misdemeanor.
A standalone pathway, not a sub-class
This credential stands on its own feet inside the tradesman framework. It has its own eligibility table, its own examination portion with its own outline, and its own passing score — none borrowed from, shortened from, or credited against the journeyman credential’s. No source states that a holder must work under a journeyman or master, and no source states a credit or conversion toward the journeyman examination; this page states neither, in either direction.
What the framework does state is one express upward relation, and it is a significant one: holding a valid Residential HVAC license for 3 years is one of the three routes that qualify a candidate for the Master HVAC examination. The residential pathway is therefore both a complete destination — a full license for the dwelling-and-townhouse scope — and a documented feeder into the top individual level, reachable without first passing through the journeyman gate. Candidates choosing between pathways should weigh exactly that trade: narrower building scope, years that lead further.

Its own portion: 55 items shaped to the residential scope
Residential candidates do not sit a shortened version of the shared Journeyman/Master portion. They sit a separate portion — 55 items in 120 minutes, open book — with its own outline. The regulatory block here totals 8 items: standards of practice 3, standards of conduct 2, renewal and reinstatement 1, definitions 1, and qualification for licensure 1, keyed to 18VAC50-30. The trade block follows the dwelling universe the license serves: warm air heating 8, air conditioning 6, ventilation 4, duct systems 4, chimneys, flues and vents 4, hot water piping 4, hot water heaters 3, controls 3, combustion air 2, insulation 2, refrigerants 2, refrigerant piping 2, chilled and condenser water piping 1, fuel oil piping and storage 1, and firestopping 1.
Read against the shared portion, the outline’s omissions are as instructive as its contents: there are no boiler items, no commercial kitchen venting items, and no revocation-of-licensure item — consistent with the residential scope, in the fact record’s own phrase. A candidate preparing from journeyman material would study two areas this portion never asks about and arrive under-prepared for the residential weighting that replaces them, where warm air heating alone matches the largest single area on either HVAC outline. Preparation for this license starts from this outline, not from the shared portion’s.
The passing score is 39 on the 55-item portion — a raw count of correct answers, exactly as the bulletin publishes it, and the only form in which this package states it. Board approval precedes the sitting, as for every tradesman examination: candidates must have completed all Board education and experience requirements before applying, the Board approves all applications for testing, and scheduling with PSI follows. The bulletin’s general tradesman rules govern the sitting — candidates bring their own references, none are provided, no study guides are permitted, references may be highlighted, underlined, and indexed beforehand but must contain no writing, only permanent tabs are allowed, and writing in references during the session brings confiscation and a report to the Department. 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 in full; examination fees are neither refundable nor transferable and remain valid one year from payment.
The residential ladder: shorter pairings, same discipline
Eligibility for this examination is set by the residential table at 18VAC50-30-39, which pairs formal vocational training with practical experience in five combinations, any one of which qualifies: 160 hours of training plus 2 years of experience; 120 hours plus 3 years; 80 hours plus 4 years; 40 hours plus 5 years; or no formal training plus 6 years. Set beside the journeyman table in the same section — which runs two years longer at its experience-only end — the residential ladder is the framework’s shortest examined route into licensed HVAC work, priced to the narrower scope it certifies. It is nonetheless a real gate: the pairings are fixed, a candidate short in one column cannot average across rows, and the file must be documented before the Board will approve testing.
The general applicant requirements apply identically: at least 18 years old, documentation of identification, vocational training, and experience, compliance with the Board’s examination-conduct rules, an address of record, and disclosure of 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, inspectors, employers, contractors, engineers, architects, or clients; education by transcript or diploma copy; and up to 40 hours of Board-approved continuing education may count toward formal vocational training. An incomplete application process lapses after 12 months. No residential-specific exemption, grandfather route, or conversion is stated in the sources: the framework’s apprenticeship exemption is stated for the journeyman examination, and this package does not extend it to this portion in either direction.
Tested code, residential references, and the field layer
Code questions on the Residential HVAC examination are keyed to the International Mechanical Code, 2021 edition, as they are for the shared portion. The bulletin’s reference tags give this portion two references of its own: the listed International Mechanical Code 2021 entry tagged for Residential HVAC, and Manual J — Residential Load Calculation, published by ACCA — which the bulletin tags as a Residential-only reference. Load calculation is therefore examined ground for this license in a way it is not for the shared portion, and a preparation plan that treats Manual J as optional misreads the reference list. The all-tradesman regulatory reference, 18VAC50-30, completes the set. No fuel gas code, no National Electrical Code, no Virginia code volume, and no USBC volume appears on the list.
The adopted layer remains separate. Field work under this license is governed by the Uniform Statewide Building Code, 2021 edition, effective January 18, 2024 — for this credential, in the part applicable to dwellings and townhouses. Tested and adopted stay distinct even though both layers carry the 2021 mechanical code, and Virginia amendments do not change examination answers. The framework’s open reference question applies here as well: 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 tags attached to entries in that block name a different trade, and this portion’s single fuel-oil item does not settle the conflict. Whether NFPA 31 is an allowed or required reference for this portion is unresolved, and this page resolves it in neither direction; confirm with PSI or DPOR before relying on it.
Fees, stated by instrument and never merged
The examination fee for the Residential HVAC examination is $100, paid to PSI. The Board’s license fees under 18VAC50-30-90 are the framework’s standard schedule and 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 — nonrefundable, not prorated, and active one year from receipt. No residential-specific regulatory ceiling on examination charges is stated in the sources for this credential, and none is printed here. The PSI figure and the Board figure are presented side by side and never combined into a single total, because neither party publishes one.
Holding the license: the same three-year machinery
This license runs on the tradesman chapter’s standard clock: valid for three years from issuance, expiring three years from the last day of the month in which it was 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. Failure to receive a renewal notice does not relieve the duty to renew, and the Board’s date of receipt, not the postmark, determines renewal against reinstatement. If renewal is not completed within 30 days of expiration, reinstatement at $210, including the $160 renewal fee, is available up to 24 months after expiration, keeping the same license number and continuous standing. Beyond that window 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 the holder counting residential years toward the Master route, continuity matters twice over: the 3 years toward Master eligibility are years holding a valid license, and a lapse puts both the credential and the count at risk.
What the PassProfessor program will cover
The residential outline, prepared as its own outline. This program is built on the 55-item portion as published: its 8-item regulatory block, its dwelling-weighted trade areas, and the areas it pointedly omits — no boilers, no commercial kitchen venting — left out of the syllabus rather than carried over from journeyman material. Manual J load calculation is prepared as listed reference ground, and the tested national IMC 2021 is taught in its own layer, separate from the USBC provisions governing the dwelling work itself.
Scope judgement as a study skill. Because this license’s boundary is a building-type line, the program trains the sorting the definition demands: dwelling and townhouse work inside the credential, commercial, industrial, institutional, and government-use structures outside it, with no invented size limits filling the gaps the regulation leaves open.
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; the Board alone licenses tradesmen. The scope, ladder, and sitting are worked in full in the companion guide at /virginia-residential-hvac-mechanic-exam-guide/.

Frequently asked questions
Why does the regulation call this credential by a different name?
The regulation’s defined term at 18VAC50-30-10 is Residential HVAC tradesman; the program name follows the catalogued name, Residential HVAC Mechanic, and the bulletin heads the portion RESIDENTIAL HVAC. They are one credential, and this package states that duality once, plainly, rather than substituting either name silently.
What buildings may a holder of this license work in?
Dwellings and townhouses, as defined in the Virginia Residential Code, and structures annexed to them. Commercial, industrial, institutional, and government-use structures are excluded by the definition itself.
How does the Residential examination differ from the Journeyman examination?
It is a separate portion: 55 items in 120 minutes, with its own outline — including Manual J as a listed reference, and no boiler or commercial kitchen venting items — against the shared Journeyman/Master portion’s 85 items in 210 minutes.
What score passes the Residential HVAC examination?
A passing score of 39 on the 55-item portion — a raw count of correct answers, exactly as the PSI bulletin publishes it.
What training and experience qualify me?
Any one pairing in the residential table at 18VAC50-30-39: from 160 hours of formal vocational training plus 2 years of experience, to no formal training plus 6 years.
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.
When does enrollment open?
