Mississippi to Connecticut: journeyman HVAC technician license reciprocity
Mississippi does not issue a statewide journeyman HVAC technician license, so there is nothing to transfer. Here is Connecticut'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.
Journeyperson by equivalent out-of-state license (all states)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
An HVAC technician licensed in any other state applies under DCP's 'Heating Journeyperson - Equivalent Out of State License' path. DCP reviews one out-of-state license for equivalency: it must have required the same number of classroom hours (576 for the S-2), an equivalent classroom curriculum matching DCP's Exhibit A courses, and the same on-the-job training hours (8,000 for the S-2) as the Connecticut license applied for; the limited D-2 class needs 4,000 OJT and 432 classroom hours and the B-2 needs 2,000 and 288. The applicant submits a copy of the license, an official license verification, the laws and regulations that set the requirements met to obtain it, and the scope of work for that license; only one license will be reviewed and the $90 application fee is non-refundable. If the license is found equivalent, DCP approves the applicant to sit the S-2 exam with PSI ($59 per portion, eligibility valid one year), and the license is issued after passing on payment of the $120 initial license fee. The out-of-state license does not waive the Connecticut exam because Connecticut has no reciprocal agreements. If the license cannot be shown equivalent, the applicant must instead document 576 classroom hours and 8,000 OJT hours with transcripts and notarized employer letters under the equivalent experience and training path.
DCP's out-of-state license page does not itself restate that the exam is required; the exam requirement follows from the Heating, Cooling and Sheet Metal Work Licenses page (every individual applicant must take an exam), CGS 20-334a(a)(2) (competency shown by the state licensure examination) and the PSI bulletin (the State determines eligibility, then the candidate tests). CGS 20-333a permits licensure without examination only where the other state reciprocates for Connecticut licensees, and DCP states no such agreements exist. Many states issue a single HVAC or refrigeration license rather than a heating-piping-cooling license with a 576-hour curriculum, so an applicant may be found equivalent only to a limited class such as the D-2. Neither DCP page mentions EPA Section 608; it is a federal requirement that applies regardless. Typical processing time is not published.

How Connecticut licenses journeyman HVAC technicians
Connecticut journeyman HVAC technician · “S-2 Unlimited Heating, Piping and Cooling Journeyperson”
Statewide license
Connecticut licenses HVAC work statewide through the Department of Consumer Protection (DCP) as 'heating, piping and cooling' work; the journeyman-level credential is the S-2 Unlimited Heating, Piping and Cooling Journeyperson, which covers all heating, piping and cooling work defined in CGS 20-330 while employed by a licensed contractor. Narrower journeyperson classes exist for technicians whose experience is limited to part of the trade, chiefly the D-2 Limited Warm Air, Air Conditioning and Refrigeration Journeyperson (no oil burner servicing) and the B-2 Limited Gas and Oil Burner Journeyperson, plus D-4 cooling-only, G-2 gas piping and S-10 light heating-cooling classes. A new S-2 applicant qualifies through a Connecticut apprenticeship, through equivalent experience and training (8,000 on-the-job hours and 576 classroom hours), or by holding an equivalent out-of-state license, and in every path must pass the PSI-administered S-2 exam (70 questions, 3 hours, 70%, open book). DCP states that Connecticut does not have reciprocal agreements with any other jurisdiction, even though CGS 20-333a would allow the Commissioner to waive the exam for licensees of states that reciprocate. The application fee is $90, the exam is $59 per portion and the initial license fee is $120; licenses expire every August 31 and renew for $120. EPA Section 608 refrigerant certification is a separate federal requirement for anyone handling refrigerants.
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.
