Missouri to Arkansas: journeyman HVAC technician license reciprocity
Missouri does not issue a statewide journeyman HVAC technician license, so there is nothing to transfer. Here is Arkansas'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.
HVACR registration (required of everyone; no exam, no credential transfer)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
An HVAC journeyman or technician arriving from any state who wants to work as an employee in Arkansas registers with the HVAC/R Section as an HVACR Registrant. The employer's designated license holder (Class A-E) signs the registrant application, the $25 registration fee is paid, and the registration is renewed every year; there is no exam, no experience requirement and no continuing education for registrants. An out-of-state journeyman license gives no advantage because nothing is waived and nothing is required beyond the registration itself. A journeyman who instead wants to contract independently, or who holds an out-of-state contractor-level license, applies for a Class A-E HVACR license under the master-level rules, where a substantially similar out-of-state license waives the exam.
Registrants may perform work only for the HVACR licensee who registered them (rule §III(19)). Low-income applicants may request a waiver of the initial fee (Act 725). Arkansas pages do not mention EPA Section 608; it is listed because it is a federal requirement.

How Arkansas licenses journeyman HVAC technicians
Arkansas journeyman HVAC technician · “HVACR Registrant”
Statewide license
Issued by Arkansas HVACR Licensing Board (Department of Labor and Licensing, HVAC/R Section)
Arkansas has no journeyman HVAC license; the person-held credential for an employee who performs heating, air conditioning or refrigeration work is the HVACR Registrant registration issued by the Department of Labor and Licensing. Ark. Code §17-33-303(c) lets an individual perform HVACR work under a Class A, B, C, D or E license holder by registering with the department and paying an annual fee ($25), and every licensee is responsible for making sure each HVACR employee holds a current registration or license. Registration is not credential-based: the one-page application asks for no experience, education, exam or prior license and is signed by the employer's designated license holder, so it must be obtained by everyone regardless of any journeyman or technician license held in another state, and no out-of-state license shortens or replaces it. A registrant may work only for an HVACR licensee; under §17-33-104 a registered individual cannot be required to obtain any city or county license, though local permits and inspections apply. The Board has no reciprocal agreements with any state at any level. Federal EPA Section 608 certification is separately required of anyone who handles refrigerants.
Why Missouri has nothing to transfer
Missouri journeyman HVAC technician
Licensed by cities and counties
Missouri does not issue a journeyman HVAC license and has no state HVAC or mechanical board; the Division of Professional Registration's list of licensed professions contains no heating, air conditioning, refrigeration or mechanical contractor profession, and the only statewide construction credential is the voluntary electrical contractor license. HVAC technicians are licensed, where they are licensed at all, by cities and counties under their own ordinances: Springfield certifies Journeyman Mechanical craftsmen on an ICC exam, St. Louis County licenses mechanical journeymen through its Board of Examiners for Mechanical Licensing, Kansas City certifies trade supervisors and licenses mechanical contractors, and the City of St. Louis licenses mechanical contractors and journeyman pipefitters. Requirements, exams and fees differ in each place and there is no statewide reciprocity. A journeyman arriving from another state must apply in each jurisdiction where they will work; the widespread use of ICC and Prometric exams means a matching passing score is often accepted in place of retesting (Springfield accepts an identical Prometric, Experior, Block or ICC exam score of 75% or better, and Kansas City may accept another jurisdiction's comparable exam). EPA Section 608 refrigerant certification is a separate federal requirement that applies statewide.
How local licensing works in Missouri
How local licensing works. Missouri has no state HVAC license and no statute standardizing local HVAC licensing, so each city or county that licenses mechanical tradespeople does so under its own building code and ordinance. The credentials below are the ones published by the largest jurisdictions.
Springfield. Building Development Services certifies Journeyman Mechanical craftsmen. Eligibility is 4 years under the supervision of a master in the trade or 6 years of experience in the trade, documented on notarized employer experience forms reviewed by the Building and Trades board (first Thursday of each month); approval to test is good for one year. The exam is the ICC mechanical exam through Pearson Vue (about $125 paid to Pearson Vue), 75% to pass, after which the city issues the certification card for $25 (renewal $25 per year). An applicant licensed elsewhere may apply for 'Reciprocation' by submitting a copy of their other-state licenses and an exam score notification of 75% or better from Prometric, Experior, Block or ICC, provided the exam is identical to the one Springfield requires; otherwise they test.
St. Louis County. The Board of Examiners for Mechanical Licensing licenses mechanical apprentices and journeymen and certifies mechanical contractors; applications go through the Accela permitting portal. An applicant approved to test must sit the journeyman exam within one year of approval (Rule 4), a temporary six-month project-specific journeyman license is available for a $45 application fee to applicants who meet the regular criteria (Rule 1), and renewal requires 12 Professional Education Units (24 hours) every three years (Rule 3). The board's rules do not provide for acceptance of another state's license; the only testing exemption (Rule 6) is for pipefitting and sprinkler-fitting journeymen licensed under the county plumbing code. The specific journeyman categories (such as HVAC Servicer-Installer) and the experience hours required to test could not be confirmed from the pages that could be opened; contact [email protected].
Kansas City. The city does not issue a separate journeyman HVAC card. City Planning and Development licenses mechanical contractors and requires each to employ a full-time supervisor holding a Kansas City certificate of qualification in the mechanical trade, earned by application with notarized references and a passing score from Prometric or ICC ($60 application, no charge for the first four-year certificate, $181 renewal every four years); comparable exams from other jurisdictions may be accepted if the city deems them equivalent or superior. Non-supervising technicians work under the licensed contractor.
City of St. Louis. The Mechanical Contractors Board of Examiners (Ordinance 62579, City Code 25.10) examines mechanical contractors and journeyman pipefitters; mechanical permits are issued only to contractors licensed by the Building Division's Mechanical Section. No HVAC journeyman license or reciprocity is published.
Out-of-state holders. No Missouri jurisdiction publishes reciprocity with another state's journeyman HVAC license. The practical route is to present an identical ICC or Prometric mechanical exam score where the jurisdiction accepts one (Springfield, and case by case in Kansas City), document experience, and apply locally; otherwise take the local exam.

State HVAC boards commonly require it before licensure, but it is not itself a state license.
