Nevada to West Virginia: journeyman HVAC technician license reciprocity

West Virginia issues a statewide HVAC Technician license through the Division of Labor under W. Va. Code 21-16 and rule 42CSR34; since January 1, 2016 every person performing heating, ventilating and cooling work must hold an individual Division of Labor license, and W. Va. Code 21-16-9 bars cities and counties from requiring any other HVAC license. The HVAC Technician is the state's full-scope person-held credential (residential and non-residential systems, work without supervision) and is the equivalent of a journeyman card; a limited HVAC Residential Technician license and an HVAC Technician-in-Training registration also exist. A new applicant documents at least 2,000 hours of HVAC-related work, training or experience (by records or sworn affidavit; a military HVAC course substitutes for veterans), pays the $75 annual license fee, and scores 70% on the computer-based WV HVAC Technician exam given by Prov ($59.95, International Mechanical Code based); licenses run one year and renew for $75 with a $25 late fee. Out-of-state technicians have two routes that waive the written exam: 42CSR34 section 15.1 lets the Commissioner license, without examination, a technician licensed by another state with equivalent requirements, and the Review and Credential Acknowledgement Procedures Act (W. Va. Code 21-17-3) requires licensure of a person who has held a similar out-of-state license for at least one year, met that state's education and exam requirements, is in good standing and has established West Virginia residency; a person with two years of HVAC work in a state that does not license the trade can qualify on experience under 21-17-4. The Division publishes no bilateral reciprocity agreements for technicians. EPA Section 608 refrigerant certification is a separate federal requirement.

Nevada has no statewide journeyman or technician license for heating, air-conditioning or refrigeration work. The Nevada State Contractors Board (NSCB) licenses refrigeration and air-conditioning contractors under classification C-21 (NRS/NAC 624), issues licenses only to businesses with a qualifying individual, and its FAQ confirms it does not license individual journeymen, so an out-of-state HVAC journeyman license has nothing to transfer to at the state level and is not needed to work for a licensed C-21 contractor in most of the state. A personal credential exists only under local building codes in the Las Vegas valley: Clark County Code §22.02.250 and the City of Las Vegas Administrative Code §306 both require a mechanical qualified individual or a journeyman HVAC mechanic to be present in a supervisory capacity whenever permitted mechanical work of residential or light-frame construction is under way, and Clark County Code §22.02.260 defines the Journeyman HVAC Mechanic category. The credential is a county photo certificate earned by passing the journeyman HVAC exam accepted by the Building Official, historically ICC exam 459 (80 open-book questions on the Uniform Mechanical Code, 4 hours, $100) followed by a $10 ID card valid three years and renewed for $30 with 15 hours of UMC continuing education. Neither jurisdiction publishes a waiver or equivalency for an out-of-state license; Clark County's only equivalency is for a certificate from its accepted testing agency or another Nevada political subdivision within the county. Reno requires journeyman cards for electrical and plumbing work only, and the rural counties were not surveyed. EPA Section 608 certification applies federally to anyone handling refrigerants.
