Mississippi to District of Columbia: journeyman HVAC technician license reciprocity
Mississippi does not issue a statewide journeyman HVAC technician license, so there is nothing to transfer. Here is District of Columbia'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.

Out-of-state journeyman HVAC technician (any state)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
The Board of Industrial Trades publishes no reciprocity for refrigeration and air conditioning mechanics, so a journeyman-level HVAC licensee from any state applies through the DLCP online portal as a new applicant. The application needs a passport-style photo, government ID, the $65 application fee, tax records and an employment verification letter signed by a master mechanic showing at least 3 years of experience, and a CFC Universal certification; the applicant then schedules the open-book journeyman exam with PSI (2012 International Mechanical Code and Modern Refrigeration and Air Conditioning) and pays the $110 license fee for a term ending September 30 of the next even-numbered year. Two statutory routes can waive the exam: D.C. Code § 47-2853.202(d) requires the Board to accept a certificate from a national certifying organization (a registered trade organization, non-union sponsor or labor union) that the applicant completed its apprenticeship, passed its exam and is designated a journeyman, and § 47-2853.12(b) directs boards to waive the exam for a licensee in good standing of a state whose standards were at least as high as the District's and which admits DC licensees in a like manner, with § 47-2853.08 leaving the substantial-equivalence finding to the Board case by case. No District-law exam applies; § 47-2853.12(c)(4) exempts journeyman refrigeration and air conditioning mechanics from one.
PSI's District of Columbia candidate bulletin lists the journeyman refrigeration exam fee as $52 per attempt. Whether experience letters signed by an out-of-state master are accepted, and which states or national certifying organizations the Board has listed under § 47-2853.12(d), are not stated in the Board's published materials. The 3-year experience figure comes from DLCP's application instructions; the statute itself sets no journeyman experience term.

How District of Columbia licenses journeyman HVAC technicians
District of Columbia journeyman HVAC technician · “Journeyman Refrigeration and Air Conditioning Mechanic”
Statewide license
Issued by DC Board of Industrial Trades (Department of Licensing and Consumer Protection)
The District of Columbia licenses HVAC technicians as Refrigeration and Air Conditioning Mechanics through the Board of Industrial Trades in the Department of Licensing and Consumer Protection (DLCP), the same board that licenses electricians and plumbers. Three person-held credentials exist: apprentice (registered without exam), Journeyman Refrigeration and Air Conditioning Mechanic, and Master Refrigeration and Air Conditioning Mechanic (regular, or limited to systems of 25 compressor horsepower and below). 17 DCMR § 303.7 requires a journeyman license for anyone doing the mechanical work of installing, maintaining, repairing or replacing refrigeration and air conditioning equipment. DLCP's application instructions require 3 years of experience verified by a master, tax records, a CFC (EPA 608) Universal certification, and a PSI-administered open-book journeyman exam; a graduate of a registered apprenticeship program (classroom work plus 8,000 hours over 4 years under a master) may waive the journeyman exam, which mirrors the national-certification substitute in D.C. Code § 47-2853.202(d). Fees are a $65 application fee and a $110 mechanic license fee; all refrigeration licenses expire September 30 of even-numbered years. The Board publishes reciprocity for electricians and plumbers from Maryland and Virginia but none for refrigeration and air conditioning mechanics.

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.
