Mississippi to Massachusetts: journeyman HVAC technician license reciprocity
Mississippi 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 Mississippi has nothing to transfer
Mississippi journeyman HVAC technician
Licensed by cities and counties
Mississippi does not issue a journeyman HVAC license. The Mississippi State Board of Contractors (MSBOC) licenses contracting businesses (commercial HVAC/mechanical contractors on projects over $50,000 and Residential HVAC contractors on residential work above the residential thresholds) through a Certificate of Responsibility held by the company and a tested qualifying party, and its FAQ states that it does not license individual journeymen; none of its exams or reciprocity agreements apply to a technician who only wants to work for an employer. Individual HVAC mechanics are licensed, where they are licensed at all, by cities under their own ordinances: Southaven issues Apprentice, Journeyman and Master Mechanical licenses and accepts a current journeyman license from another jurisdiction or a passed ICC journeyman exam in place of its own testing, while Gulfport licenses only the Mechanical/HVAC contractor's qualifying party and has no journeyman card. An out-of-state journeyman HVAC license has no state-level recognition in Mississippi; the technician must check the ordinance of each city where they will work and apply locally, and Southaven-style acceptance of another jurisdiction's card or an ICC score is the closest thing to reciprocity that exists. EPA Section 608 refrigerant certification is a separate federal requirement that applies everywhere in the state.
How local licensing works in Mississippi
How local licensing works. Mississippi's contractor law is enforced by MSBOC at the business level; there is no state journeyman or technician card and no statute standardizing city trade licenses. Cities that license individual mechanics do so under their own ordinances, and most coastal and metro cities instead license the contractor or its qualifying party.
Southaven. The Building Department issues Apprentice Mechanical ($20), Journeyman Mechanical ($50) and Master Mechanical ($100) licenses. A journeyman applicant files the application with photo ID and either a copy of a current, active journeyman license held in another jurisdiction or written proof of passing the ICC journeyman exam; no Southaven exam is given. Work must follow the 2024 International Mechanical Code. The city refers all questions about out-of-state reciprocity to MSBOC.
Gulfport. Building Code Services issues a Mechanical/HVAC contractor license in the name of the company's qualifying party ($100, waived for holders of an MSBOC Certificate of Responsibility) with a notarized application, five reference letters (not required with an MSBOC license), $100,000/$300,000 liability insurance naming the city and a home-jurisdiction privilege license. In practice a journeyman card from another jurisdiction or a passing ICC journeyman mechanical score is accepted by Southaven, and elsewhere the technician simply works under a locally licensed contractor.
