Nevada to Massachusetts: journeyman HVAC technician license reciprocity
Nevada does not issue a statewide journeyman HVAC technician license, so there is nothing to transfer. Here is Massachusetts's standard path for out-of-state applicants.
Your origin state does not issue a statewide license at this level, so there is no license to transfer. The destination's standard out-of-state path is shown; expect to meet it in full.
Reference only, not legal advice. Rules change; confirm with the licensing board before you apply. Full disclaimer.
Refrigeration Technician by examination with out-of-state license and experience credit (all states)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
An HVAC or refrigeration technician licensed in any other state applies to OPSI for the Refrigeration Technician examination through the MyLicenseOne portal, submitting a copy of the out-of-state refrigeration technician, master technician or equivalent license together with employer documentation showing work experience and certifications equivalent to the Massachusetts prerequisites (6,000 hours plus 250 schooling hours, or the other combinations allowed until November 9, 2026). The form lets the applicant certify that all experience was obtained outside Massachusetts in place of holding a Massachusetts apprentice license, and 528 CMR 11.07(1) lets the applicant petition the Bureau in writing to accept the out-of-state license, including the experience and education obtained for it, as substantially equivalent; approval requires a majority vote of the Bureau, which may grant the request in whole or in part or deny it, and gives no credit for work done in a jurisdiction that does not license the trade. Every applicant also submits a high-school diploma or GED, a copy of a Universal EPA Section 608 certification, a 2x2 photo and the $75 non-refundable fee. Because the Bureau has no reciprocity agreement with any state, the Massachusetts exam is never waived; applicants are told of their eligibility about four to eight weeks after receipt, test first come first served, and must score 70% or better. The license renews for $50.
528 CMR 11.07(1) conditions licensure without examination on a reciprocity agreement with the origin jurisdiction; no such agreement is published on any Bureau page or in 528 CMR, so every state is treated the same. The Refrigeration Technician how-to page and application list only the $75 application fee; no separate exam fee or initial license fee is published (M.G.L. c. 146, § 85 leaves fee amounts to the commissioner of administration). The ten-ton threshold means technicians working only on smaller residential and light-commercial systems need no Massachusetts license at all, but EPA Section 608 still applies.

How Massachusetts licenses journeyman HVAC technicians
Massachusetts journeyman HVAC technician · “Refrigeration Technician (Journeyman Refrigeration Technician)”
Statewide license
Massachusetts has no general HVAC license. The state credential that functions as the journeyman-level HVAC license is the Refrigeration Technician license (called 'journeyman refrigeration technician' in M.G.L. c. 146, § 81), issued by the Bureau of Pipefitters, Refrigeration Technicians and Sprinkler Fitters within the Office of Public Safety and Inspections (OPSI); it is required of anyone who performs refrigeration work on systems of ten tons or more in the aggregate, which covers commercial air conditioning and refrigeration. Heating-side work is licensed separately as pipefitting (OPSI) and oil burner service (Department of Fire Services), and residential systems under ten tons require no state refrigeration license beyond federal EPA Section 608 certification. A new technician needs a high-school diploma, an EPA Section 608 Universal certification, and either 6,000 hours as a licensed Massachusetts refrigeration apprentice plus 250 hours of approved schooling (rising to a 450-hour course plus 6,000 hours for applications filed on or after November 9, 2026), then must pass the OPSI-administered exam at 70%. The application fee is $75 and the license renews for $50. Under 528 CMR 11.07 a technician licensed in another state may petition the Bureau to treat that license, with its experience and education, as substantially equivalent, but every applicant must pass the Massachusetts exam unless a reciprocity agreement exists, and the Bureau publishes none.
Why Nevada has nothing to transfer
Nevada journeyman HVAC technician
Licensed by cities and counties
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.
How local licensing works in Nevada
How local licensing works. NRS Chapter 624 licenses only contractors. A C-21 Refrigeration and Air-Conditioning license (NAC 624.380, with subclassifications C-21a Refrigeration through C-21g Industrial Piping) is issued to a business and qualified by an individual with four years of journeyman-or-higher experience; the NSCB's own FAQ says it does not license individual journeymen. Whether a working HVAC mechanic needs a personal card is decided by each county's or city's building administrative code, and only the southern Nevada jurisdictions were found to require one.
Clark County (unincorporated Las Vegas valley, Laughlin and other unincorporated areas). Clark County Code §22.02.245 issues mechanical permits only to contractors holding an active Nevada C-21 license. §22.02.250(B) requires the contractor to employ at least one mechanical qualified individual and, as amended in 2010 by Ordinance 3899, to have a mechanical qualified individual or a journeyman HVAC mechanic present during work hours in a supervisory capacity on every job site where permitted mechanical work of residential or light-frame construction is being performed. §22.02.255 defines a journeyman as someone who has passed the appropriate journeyman examination accepted by the Building Official and makes certificates renewable; §22.02.260(A)(9) lists 'Journeyman HVAC Mechanic - all aspects of mechanical work; mechanical work of residential and light frame construction' and requires certificates to be kept current with the county's accepted third-party testing agency. The only equivalency in the code (§22.02.255(C)) is for a current certificate from an accepted independent testing agency or from a Nevada political subdivision inside Clark County; there is no provision for other states' licenses, and unlike plumbing no experience prerequisite is stated for the HVAC exam. Under the county's ICC bulletin (June 30, 2014) the exam is ICC 459 Nevada (Clark County) Journeyman HVAC Mechanic: 80 multiple-choice questions, open book, 4 hours, $100, scheduled through Pearson VUE; the ID card costs $10, is valid three years, and is renewed for $30 with 1.5 CEUs (15 hours) on the current Uniform Mechanical Code and local amendments from approved providers (CSN, IAPMO, ICC, SMWIA, NATE, OSHA, RSES, SMACNA); a card expired more than one year requires re-examination.
City of Las Vegas. The City of Las Vegas Administrative Code (2019 edition) §306 carries the same rule: at least one mechanical qualified individual on staff, and a mechanical qualified individual or journeyman HVAC mechanic on site in a supervisory capacity for permitted residential or light-frame mechanical work, with certifications issued or approved by the city. The county's pages do not say who now proctors the journeyman HVAC mechanic exam and issues the card; applicants should confirm with the Clark County Department of Building and Fire Prevention before scheduling.
Out-of-state holders. No jurisdiction publishes a reciprocity or endorsement path for an out-of-state HVAC journeyman or technician license. The practical route is to pass the Clark County journeyman HVAC exam once and obtain the county card, which is honored in the City of Las Vegas; EPA Section 608 certification is required separately under federal law.
