West Virginia’s HVAC Residential Technician license, issued by the West Virginia Division of Labor alone under West Virginia Code §21-16 and 42 CSR 34, licenses residential heating, ventilating, and cooling work on the holder’s own authority — and nonresidential work only under a licensed HVAC Technician’s direct supervision. Its route runs through section 7 of the rule, which states no experience-hours gate, to a 60-question, open-book Prov examination keyed to the International Mechanical Code 2024. The PassProfessor West Virginia HVAC Residential Technician program prepares candidates for that examination and for the conditions the license carries.

This guide is organized around the condition that defines the credential, because that is how the rule itself is organized. The license’s name promises a boundary; its definition and its supervision rule draw the boundary precisely; its eligibility section is written more shortly than its sibling’s, on purpose; and its examination weights the regulatory material that tests whether a candidate understands the boundary as heavily as the installation material that tests the trade. A candidate who prepares for this license as a smaller copy of the full Technician license will misread all four facts. The distinction is not size — it is structure. The program page, West Virginia HVAC Residential Technician Exam Preparation, states the credential in brief; this guide works through the condition, the route, and the sitting in full.
Reading the verified facts
Facts in this guide sit in layers, and the layering is the discipline. Statute facts come from West Virginia Code §21-16: the license requirement, and the design statement that the residential examination is commensurate with the scope of practice for HVAC residential technicians and was developed in consultation with HVAC industry representatives. Rule facts come from 42 CSR 34, effective May 1, 2023: the Division’s enforcement role at section 2.2; the definitions at sections 3.5, 3.8, and 3.11; the complete eligibility text at section 7; the supervision caps at section 9; the fees at section 10; the examination standard at section 11; and the without-examination routes at section 15. Bulletin facts come from the Prov candidate information bulletin: the 60 questions, the 180 minutes, the open-book status and its exact discipline, the eight-area outline, the tested references, and the retake and rescheduling mechanics. Code-adoption facts come from 87 CSR 4, whose text in force adopts the 2018 editions of the mechanical and residential codes. One discipline governs the silences: where a layer does not speak — and section 7’s silence on experience hours is the most consequential example — this guide reports the silence as the text’s own fact and builds nothing on top of it.
One issuer: the Division of Labor, alone
The HVAC Residential Technician license is a Division of Labor license, issued through the Commissioner of Labor. Section 34-2.2 vests enforcement of the governing rule in the Division of Labor, and no other body shares the role. The Contractor Licensing Board administers the contractor tier under West Virginia Code §30-42 — a separate apparatus for a business-facing credential — and does not issue this license. The rule at 87 CSR 4 belongs to the State Fire Commission and functions here only as the code-adoption instrument described below; it is not this license’s rule. The examination arrangement follows the same pattern: at 42 CSR 34-11.4.1, the rule authorizes the Commissioner to contract with a private testing agent, with applicants paying the examination fee directly to that agent. Prov is that agent. A candidate who keeps the three bodies straight — Division as issuer, Prov as examination agent, Fire Commission as code adopter — has the framework’s map before any trade content is studied.
The supervision condition, in the rule’s own words
Start where the rule starts: with the definition. The Division publishes the credential’s scope as follows — an HVAC Residential Technician is a person licensed to install, test, maintain, and repair residential heating, ventilating, and cooling systems, provided that such persons may perform work on nonresidential systems subject to rules promulgated by the Commissioner under the Act. The proviso is not boilerplate. The rule it points to is 42 CSR 34-3.5, which defines “direct supervision” to include the direction, oversight, and control of a licensed HVAC residential technician by a licensed HVAC technician on non-residential HVAC systems. Put definition and rule together and the license’s operating shape is exact:
On a residential system, the holder works on the license’s own authority, without any supervision condition in the text. On a non-residential system, the holder may work, but only inside the direction, oversight, and control of a licensed HVAC Technician. The word “Residential” in the license’s name is therefore a summary, not the rule: the rule is the condition, and a candidate who memorizes the name without the condition will misjudge real jobs and examination scenarios alike. It also follows that the full HVAC Technician is not merely a bigger license here — for nonresidential work, the Technician is the named supervisor inside this license’s definition. This guide states the sibling’s figures only where the distinction requires them.
Drawing the line: the four nonresidential triggers
A condition is only usable if its trigger is knowable in advance, and the rule supplies the test at 42 CSR 34-3.11. A system is non-residential if it meets any one of four tests: more than four separate units with a combined capacity of more than 20 tons – 520,000 BTUs; use in commercial structures over 5,000 square feet; fire dampers used or required; or packaged rooftop units. The four tests capture systems by scale, by building, by life-safety component, and by equipment form, so a working technician can classify a described system from any of several directions.
Two misreadings of this definition are common enough to name directly. First, the 20-ton / 520,000-BTU figure is not a cap on this license. It is one element of the definition that decides whether a system is non-residential — and therefore whether the supervision condition applies. Printed as a standalone ceiling, it would say something the rule does not say; this guide prints it only inside the definition, where the rule puts it. Second, the rule states no dwelling-type list for this license. The classification runs through the four triggers and the supervision condition, not through a catalogue of buildings. Preparation that invents either shortcut is preparation for a rule West Virginia did not write.
Around the definition sits the framework’s standing boundary: “HVAC work” means heating, ventilating, and air conditioning or cooling work, but does not include work on refrigeration lines, steam lines, or hydronics (42 CSR 34-3.8). A license is required to perform or offer to perform HVAC work, the licensee must carry proof of license while working, and licenses are not transferable (42 CSR 34-5).
Section 7: the route, written short on purpose
Eligibility for this license lives in a single section, and its brevity is its most important feature. Section 7 of 42 CSR 34 requires, in full: a completed application and affidavit on Division forms, with the license fee set by section 10; and passage of the required written examination, except for an applicant proceeding under section 15. The license that follows is valid for up to one year, and the section’s renewal provisions close it out.
What section 7 does not contain deserves the same precision. It states no experience-hours requirement — no figure, no qualifying-settings list, no documentation standard — and no training, age, or diploma requirement. This guide prints that absence at exactly the level the text supports: as the rule’s own text, in the rule’s own section, for this license. The contrast that makes the absence meaningful stands one section earlier in the same rule, where section 6.3 requires an HVAC Technician applicant to prove at least 2,000 hours of HVAC-related work, training, and experience. The two sections were written side by side in one rule; one carries an hours gate and the other does not, and the only honest reading keeps them separate. The Technician’s 2,000 hours never borrow down into this license’s route — not as an expectation, not as an informal standard. A candidate for this license prepares the application, the fee, and the examination, because those are the requirements the governing text states.
The route, in order, is therefore short to state and exact to follow. Step one — confirm that this license’s scope, with its supervision condition, matches the work to be done; a candidate who needs unsupervised nonresidential scope is on the sibling’s route. Step two — file the completed application and affidavit on Division forms, with the $60 annual license fee. Step three — register with Prov, pay the $59 examination fee, and sit the examination. Step four — obtain a minimum score of at least 70%, in the rule’s form. Step five — hold the license for its term of up to one year, carry proof of license while working, and renew inside the mechanics below.
The examination, section by section
Prov delivers the examination by computer at its six West Virginia centers — Beckley, Charleston, Fairmont, Huntington, Martinsburg, and Wheeling — at any Prov center in the United States, or remotely from home. The sitting is offered in English, graded immediately on completion, with results forwarded to the licensing authority. Sixty questions in 180 minutes is three minutes per question — the same pace as the full license’s sitting, at three-quarters of its length.
The outline rewards a close reading. Equipment Installation and Mechanical Systems (9) and Safety Practices and Regulatory Compliance (9) share the lead. HVAC Calculations and Measurements (8) and Refrigeration Systems (8) follow. Airflow and System Performance (7) and Duct Fabrication and Sheet Metal Work (7) come next, with Duct Installation and Air Distribution (6) and Tools and Equipment Operation (6) completing the 60. Set beside the sibling examination’s outline, the residential paper’s character shows in the proportions: the compliance area holds lead weight here rather than sitting third, which fits a license whose defining fact is a regulatory condition. The rule’s design statement matches the paper to the practice: this examination tests the section 4 standards applicable to a residential technician’s scope of work for the installation, repair, and maintenance of residential HVAC systems. A study plan therefore gives the scope-and-supervision material first-class standing alongside the trade material — the bulletin already has.
The pass standard is stated in the rule, in one sentence covering both technician classifications: under 42 CSR 34-11.1, the applicant shall take the examination required for the desired classification and obtain a minimum score of at least 70%. As with the sibling examination, the bulletin’s headline line for this sitting does not itself print a percentage-to-pass element; the standard lives in the rule text, and the rule text is where a candidate should anchor it.
Open book, exactly as the bulletin disciplines it
Open book is a set of rules, not a mood, and the bulletin states them with unusual specificity. The references marked open book are permitted during the examination. The book title must be exact, while older or newer editions of a title are always permitted. Permanent tabs are permitted; repositionable tabs and sticky notes are not. Highlighting and underlining may be done in pen only, and no marking may be added during the examination itself. No handwritten notes or formulas may appear in any reference. One further provision needs careful handling: the bulletin permits a candidate to bring a different book of their choosing after signing an acknowledgement and waiver that the book was not used to develop the examination. That is a waiver mechanism for an unlisted book — it does not make the chosen book an approved reference, and preparation built on treating it as one misreads the bulletin. The practical consequence is that a candidate’s references should be prepared before the sitting — tabbed permanently, marked in pen, free of handwritten additions — and rehearsed as retrieval tools, because at three minutes per question the sitting scores how fast the governing provision can be found.
After a failed sitting
The retake mechanics are stated plainly and are permissive. An applicant who does not reach the standard is eligible to retake upon payment of the applicable examination fee. The bulletin adds that there is no limit on the number of attempts and no required waiting period between them. Rescheduling follows the vendor’s general rule: reschedule or cancel free online at least three days before the examination date, or the examination fee is forfeited. With no waiting period imposed, pacing after a failure is the candidate’s own diagnostic work — the outline areas the first sitting exposed, re-studied against the tested references, before the fee is spent again.
The two code layers, in full
The tested layer comes from the bulletin: the International Mechanical Code 2024 and Modern Refrigeration and Air Conditioning, 22nd Edition, both marked open book, with the bulletin stating that the test will be based on the reference version shown in the bulletin. The adopted layer runs through section 4 of 42 CSR 34, which incorporates the International Mechanical Code and the International Residential Code for One-and-Two-Family Dwellings as adopted in 87 CSR 4, in their entirety by reference. The 87 CSR 4 text in force, effective August 1, 2022, adopts the 2018 editions of those codes.
For this license the adopted layer has a residential center of gravity: the International Residential Code half of the section 4 incorporation governs the one-and-two-family work this license exists to perform — at the 2018 edition, while the examination’s mechanical code is 2024. Neither fact cancels the other; they live in different layers and answer different questions. Candidates who merge the layers study the field edition for a sitting keyed to a later one; licensees who merge them in the other direction install to an examination book. This guide names the layer every time an edition appears.
Fees, term, and renewal mechanics
The route’s money moves through two instruments that never merge. The examination fee is Prov’s: $59, paid to Prov at registration, under the rule mechanism that lets the Commissioner contract with a testing agent and direct applicants to pay that agent; a retake is a further examination fee. The license fee is the state’s, at this license’s own figure: $60 per year under 42 CSR 34-10.2, paid on initial application and at renewal. The sibling license’s $75 annual fee belongs to that license and appears here only to mark the distinction. Two ancillary state charges complete the picture: a $25 late fee and a $10 duplicate-license fee. No combined total is printed here, because the sources contain none.
The license is valid for up to one year unless sooner suspended or revoked. Renewal requires an application and the renewal fee on or before the expiration date, and the Commissioner sends a renewal notice at least 45 days in advance. Past the date: a renewal received or postmarked more than 15 days after expiration draws the $25 late fee, and a license expired for 90 days or more cannot be renewed. On a one-year term, that 90-day line converts a lapsed renewal into a fresh route through section 7 and the examination.
Supervision given, as well as supervision under
This license stands on both sides of the supervision structure, and a complete guide records both. As a supervisor: on residential work, a licensed HVAC residential technician may directly supervise no more than four licensed technicians-in-training — the same residential cap the rule gives the full HVAC Technician. As the supervised party: on non-residential work, supervision belongs to the licensed HVAC Technician alone, who may directly supervise no more than two licensed technicians-in-training and licensed HVAC residential technicians combined. The working picture is a license that runs trainee crews on house work and joins a capped, technician-led crew on the commercial job — with the classification of each system, under the four triggers, deciding which posture the day requires. Knowing which side of section 9 a described job puts the holder on is exactly the judgment the outline’s regulatory compliance area examines.
The section 15 routes, at their true size
Section 15 names this classification in its own terms — HVAC residential technicians are among those the Commissioner may license without examination — through two discretionary routes: reciprocity, for an applicant licensed in another state with equivalent requirements who proves compliance with the provisions the section cites; and work experience, for an applicant whose experience comes from a state that does not license HVAC work, on the proof that route specifies. Each route carries the license fee and rests with the Commissioner; neither can be claimed as of right. Older dated grandfathering provisions touching this license have expired by their own terms and are not presented here as available options. For the ordinary candidate, the route remains the one section 7 writes: application, fee, examination.
How the PassProfessor program prepares candidates
The condition first. The program is organized the way the rule is: the residential scope, the 42 CSR 34-3.5 supervision condition, and the four nonresidential triggers of 42 CSR 34-3.11 are taught as the license’s operating system, with classification practice — described system, which side of the line, whose supervision — running through the material.
Weighted to the published outline. Practice follows the bulletin’s eight areas at their published weights, with the safety and regulatory compliance area given the lead standing the bulletin gives it, and calculations and refrigeration drilled at their eight-question weight.
Keyed to the tested references, disciplined about the adopted layer. Material is written against the International Mechanical Code 2024 and Modern Refrigeration and Air Conditioning, 22nd Edition, with open-book retrieval practice built to the bulletin’s exact tabbing and marking rules, while the adopted 2018 codes are covered as the separate field layer they are.
The route stated as section 7 states it. The Division’s sole issuing role, the application-fee-examination route with no hours gate stated in its text, this license’s own $60 state fee kept apart from the Prov charge, and the one-year term with its late fee and 90-day cutoff are covered as examined regulatory substance.
Independence, stated plainly. PassProfessor is an independent preparation provider, not affiliated with the West Virginia Division of Labor or with Prov. Completing the program confers no license; the Division alone licenses, and the companion program page, West Virginia HVAC Residential Technician Exam Preparation, carries the notify form for enrollment updates.

Frequently asked questions
Who issues this license?
The West Virginia Division of Labor, through the Commissioner of Labor — alone. The Contractor Licensing Board governs the separate contractor tier and does not issue this license.
What is the governing rule?
42 CSR 34, effective May 1, 2023, under West Virginia Code §21-16. The rule at 87 CSR 4 is the State Fire Commission’s State Building Code; its role here is code adoption only.
What exactly is the supervision condition?
The license covers residential systems on the holder’s own authority. Work on nonresidential systems is permitted only under direct supervision, which 42 CSR 34-3.5 defines to include the direction, oversight, and control of a licensed HVAC residential technician by a licensed HVAC technician on those systems.
How is “non-residential” decided?
By any one of the four tests at 42 CSR 34-3.11: more than four separate units with combined capacity of more than 20 tons – 520,000 BTUs; commercial structures over 5,000 square feet; fire dampers used or required; or packaged rooftop units. The definition triggers the supervision condition — it is not a tonnage cap on residential work.
Does this license require experience hours?
Section 7 of 42 CSR 34 states the requirements as a completed application and affidavit, the license fee, and passing the required written examination — and states no experience-hours requirement. The 2,000 hours at section 6.3 belong to the full Technician license.
How many questions are on the examination, and how long does it run?
60 questions in 180 minutes, open book, offered in English, computer-administered by Prov at its West Virginia centers, at other Prov centers, or remotely from home.
What score passes?
The rule requires the applicant to obtain a minimum score of at least 70% (42 CSR 34-11.1) — the same rule sentence that governs both technician classifications.
Which references are tested, and what may be brought into the sitting?
The International Mechanical Code 2024 and Modern Refrigeration and Air Conditioning, 22nd Edition, both marked open book. Prov’s discipline applies: exact book titles (older or later editions always permitted), permanent tabs only, pen-only highlighting and underlining with no marking during the examination, and no handwritten notes or formulas in any reference.
Is the tested code the same as the code adopted for field work?
No. The examination tests the International Mechanical Code 2024. The codes incorporated for field work through 87 CSR 4 stand at the 2018 editions of the mechanical and residential codes. The layers are separate.
What does the route cost?
Two separate instruments: a $59 examination fee paid to Prov at registration, and a $60 annual license fee paid to the state under 42 CSR 34-10.2. The full Technician license’s $75 state fee is a different license’s figure. A duplicate license costs $10. No combined total exists in the sources.
What if the examination is failed?
The applicant is eligible to retake on payment of the applicable examination fee. The bulletin states there is no limit on attempts and no required waiting period between them.
How long does the license last?
Up to one year. Renewal is due on or before expiration, with notice sent at least 45 days ahead; a renewal more than 15 days late draws a $25 late fee, and a license expired for 90 days or more cannot be renewed.
Is PassProfessor affiliated with the Division of Labor or Prov?
No. PassProfessor is an independent preparation provider. The Division alone licenses HVAC residential technicians, and Prov administers the examination on the Division’s behalf.
