West Virginia’s HVAC Residential Technician license is issued by the West Virginia Division of Labor alone, under West Virginia Code §21-16 and the rule at 42 CSR 34. It licenses a technician to install, test, maintain, and repair residential heating, ventilating, and cooling systems — and reaches nonresidential systems only under a licensed HVAC Technician’s direct supervision. The license is earned on a 60-question, open-book Prov examination, on a route whose governing section states no experience-hours gate. The PassProfessor West Virginia HVAC Residential Technician program prepares candidates for that examination and for practicing inside the license’s exact conditions.

A license defined by a condition, not just a name
Most license names describe a territory. This one describes a relationship. The Division of Labor’s published definition licenses the HVAC Residential Technician to install, test, maintain, and repair residential heating, ventilating, and cooling systems — and then adds the provision that does the real work: such persons may perform work on nonresidential systems subject to rules promulgated by the Commissioner. The rule supplies that condition at 42 CSR 34-3.5, where “direct supervision” is defined to include the direction, oversight, and control of a licensed HVAC residential technician by a licensed HVAC technician on non-residential HVAC systems. Read together, they draw the license’s true shape: residential work on the holder’s own authority; nonresidential work only while a licensed HVAC Technician directs, oversees, and controls it. Everything else about this credential hangs off that single condition.
The license is one of three classifications the Division administers under 42 CSR 34, alongside the full HVAC Technician license and the HVAC Technician-in-Training license, whose holder may perform system work only under a licensed HVAC Technician’s direct supervision. The HVAC Contractor license stands outside this family entirely, in the Contractor Licensing Board’s apparatus under West Virginia Code §30-42; this is an individual technician license, not a contractor credential. The work itself carries the rule’s standing boundary: “HVAC work,” under 42 CSR 34-3.8, means heating, ventilating, and air conditioning or cooling work, but does not include work on refrigeration lines, steam lines, or hydronics. A license is required to perform or offer to perform HVAC work, and licenses are not transferable.
Who issues this license — and under what rule
The West Virginia Division of Labor, through the Commissioner of Labor, issues this license, and it does so alone; enforcement of the governing rule is vested in the Division. The statute is the Regulation of Heating, Ventilating, and Cooling Work Act, West Virginia Code §21-16-1 et seq., and the rule is 42 CSR 34, effective May 1, 2023. The rule at 87 CSR 4 — the State Fire Commission’s State Building Code — is not a licensing rule for this credential; it enters the framework only as the instrument through which the mechanical and residential codes are adopted for field work. Candidates who meet this credential first through contractor-licensing material should reset the attribution at the door: no board issues this license.

Where the line falls: what counts as nonresidential
The supervision condition only bites when a system is nonresidential, so the rule’s definition of that term is the most practical paragraph in this license. Under 42 CSR 34-3.11, a non-residential system is any system meeting 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. A residential technician reading a job against those four tests knows, before the work starts, which side of the condition the job sits on. Note what the definition does not do: it does not set a tonnage cap on residential work, and it does not list dwelling types — the 20-ton figure defines when a system becomes non-residential and the supervision condition switches on.
The route as section 7 actually writes it
Section 7 of 42 CSR 34 states this license’s requirements completely, and they are short enough to quote in substance: a completed application and affidavit on Division forms, with the license fee; and passage of the required written examination, subject only to the without-examination routes in section 15. That is the whole gate. Section 7 states no experience-hours requirement for this license — no hours figure, no training pathway, no supervision history. The contrast inside the same rule is precise and deliberate: section 6.3 requires the full HVAC Technician applicant to show at least 2,000 hours of HVAC-related work, training, and experience, and section 7 contains no counterpart. The absence is the rule’s own text, framed exactly that way — as what section 7 does and does not say.
The Prov examination: 60 questions, 180 minutes, open book
Prov administers the examination on behalf of the Division, under the rule’s own authorization for the Commissioner to contract with a private testing agent, with applicants paying the examination fee directly to that agent. The sitting is computer-administered at Prov centers in Beckley, Charleston, Fairmont, Huntington, Martinsburg, and Wheeling, at other Prov centers, or remotely from home, with results graded immediately and forwarded to the licensing authority.
The published outline distributes the 60 questions across eight areas: Equipment Installation and Mechanical Systems, 9; Safety Practices and Regulatory Compliance, 9; HVAC Calculations and Measurements, 8; Refrigeration Systems, 8; Airflow and System Performance, 7; Duct Fabrication and Sheet Metal Work, 7; Duct Installation and Air Distribution, 6; and Tools and Equipment Operation, 6. The shape is instructive: installation and safety-regulatory work share the lead, and the regulatory compliance area — the area that examines the supervision condition itself — carries the same top weight as installation. Three hours for 60 questions is a retrieval test as much as a knowledge test.
The passing standard lives in the rule, in a single sentence governing 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%. An applicant who does not reach that standard is eligible to retake on payment of the applicable examination fee; the bulletin places no limit on attempts and no waiting period between them. Rescheduling or cancelling is free online at least three days before the examination date; inside that window, the fee is forfeited.
Prov’s open-book discipline is part of the sitting: the book’s title must be exact, though older or later editions are always permitted; permanent tabs are permitted, repositionable tabs and sticky notes are not; highlighting and underlining in pen only, with no marking during the examination; and no handwritten notes or formulas in any reference. The bulletin also allows a candidate to bring a different book after signing an acknowledgement and waiver that it was not used to develop the examination — a waiver route, not a second approved-reference list. The companion guide states the full discipline.
Tested on 2024, working under 2018: the two code layers
The tested layer comes from the Prov 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 versions shown. The adopted layer runs through section 4 of the rule, which incorporates the International Mechanical Code and the International Residential Code for One-and-Two-Family Dwellings as adopted in 87 CSR 4 — whose text in force adopts the 2018 editions. For this license, the residential code half of that adoption governs daily work, at 2018, not the tested 2024. Study the 2024 code for the sitting; work to the adopted 2018 codes in the field; keep the layers separate.
Two fees, two instruments, never one figure
As with the sibling license, the money runs through two separate instruments. The examination fee is $59, paid to Prov at registration; a retake carries a further examination fee. The license fee is the state’s, at this license’s own figure: under 42 CSR 34-10.2, an initial or renewal applicant pays a $60 annual license fee. The sibling’s $75 state fee is not this license’s fee, and neither figure is combined with the Prov charge into a single total here, because the sources state none. A duplicate license costs $10.
Term, renewal, and the 90-day line
An HVAC residential technician license is valid for up to one year unless sooner suspended or revoked. Renewal takes an application and the renewal fee on or before the expiration date; the Commissioner sends a renewal notice at least 45 days in advance. 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 license, that line turns a missed renewal into a fresh application.
The license also carries a supervisory role of its own. On residential work, a licensed HVAC residential technician may directly supervise no more than four licensed technicians-in-training — the same residential cap the full Technician license carries. On non-residential work, supervision runs the other way: only the licensed HVAC Technician supervises there, over a combined maximum of two technicians-in-training and residential technicians. A holder of this license works both sides of the supervision structure, and knowing which side a given job puts them on is a working skill, not a technicality.
What the PassProfessor program will cover
The supervision condition as the organizing fact. This program in the PassProfessor catalog is built around the distinction that defines the license: residential scope on the holder’s own authority, nonresidential work only under a licensed HVAC Technician’s direct supervision under 42 CSR 34-3.5, with the four nonresidential triggers of 42 CSR 34-3.11 taught as the test a working technician runs against every job.
The outline at its published weights. Practice material follows the bulletin’s eight areas — installation and safety-regulatory compliance at the lead weight of nine each, calculations and refrigeration at eight, airflow and duct fabrication at seven, duct installation and tools at six.
The 2024 tested layer, kept separate from the 2018 adopted layer. Material is keyed to the International Mechanical Code 2024 and Modern Refrigeration and Air Conditioning, 22nd Edition, while the adopted 2018 mechanical and residential codes are taught as the field layer they are — including Prov’s exact open-book discipline for tabs, marking, and permitted references.
The West Virginia frame, stated as the rule states it. The Division’s sole issuing role, the section 7 route with no hours gate stated in its text, the two separate fee instruments at this license’s own figures, and the one-year term with its late fee and 90-day cutoff all appear as examined context, because the outline’s regulatory compliance area reaches exactly this material.
Independence, stated plainly. PassProfessor is an independent preparation provider, not affiliated with the West Virginia Division of Labor or with Prov. Completing this program confers no license and no exemption; the Division alone licenses, and candidates register for the examination through Prov’s channels. The companion guide, West Virginia HVAC Residential Technician Exam Guide, works through the scope condition and the route in full.

Frequently asked questions
Who issues the West Virginia HVAC Residential Technician license?
The West Virginia Division of Labor, through the Commissioner of Labor — the Division alone. The Contractor Licensing Board governs the separate contractor tier.
What work does this license cover?
Installing, testing, maintaining, and repairing residential systems on the holder’s own authority — plus work on nonresidential systems only under a licensed HVAC Technician’s direct supervision, as 42 CSR 34-3.5 defines it.
What makes a system nonresidential?
Any one of four tests in 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.
What does the examination look like?
Prov administers it: 60 questions in 180 minutes, open book, offered in English, computer-administered at centers in Beckley, Charleston, Fairmont, Huntington, Martinsburg, and Wheeling, at other Prov centers, or remotely from home. Results are graded immediately.
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?
The International Mechanical Code 2024 and Modern Refrigeration and Air Conditioning, 22nd Edition, both open book. The adopted field codes incorporated through 87 CSR 4 stand at the 2018 editions — a separate layer from the tested edition.
What are the fees?
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.
How long does the license last, and what happens if it lapses?
Up to one year. Renewal is due on or before expiration; a renewal more than 15 days late draws a $25 late fee, and a license expired for 90 days or more cannot be renewed.
