Missouri to Idaho: journeyman HVAC technician license reciprocity
Missouri does not issue a statewide journeyman HVAC technician license, so there is nothing to transfer. Here is Idaho'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.
Universal licensure for out-of-state HVAC journeymen (all states)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
Idaho has no HVAC reciprocity agreements, so every out-of-state journeyman is handled the same way. Under Idaho Code 67-9409 the HVAC board must license a person who holds a current, valid and unrestricted HVAC license in another state and demonstrates competency, using the standard application, fees and background checks, and it may require the applicant to take all or part of the Idaho journeyman exam; the board's own rules and the HVAC Journeyman application do not yet describe a separate universal-licensure procedure, so in practice the applicant files the $35 journeyman application, documents supervised HVAC installation hours on Work Verification Forms (out-of-state hours count toward the 16,000-hour work-experience pathway) and passes the PSI journeyman exam ($75) within one year. The board may compare the scope of the origin license to Idaho's and issue a limited license pending additional training.
The HVAC FAQ answers 'No' to whether Idaho has a reciprocal licensing agreement. Whether the board waives any part of the exam for universal-licensure applicants was not confirmed from an official page; the journeyman application requires the exam on both listed pathways. The Work Verification Form asks for the supervising journeyman's Idaho license number, so out-of-state employers should attach equivalent documentation.

How Idaho licenses journeyman HVAC technicians
Idaho journeyman HVAC technician · “HVAC Journeyman”
Statewide license
Idaho issues a statewide HVAC Journeyman certificate of competency through the Heating, Ventilation and Air Conditioning Board at the Division of Occupational and Professional Licenses (DOPL); a journeyman works in the employ and under the direction of a licensed HVAC contractor. A new applicant pays a $35 application fee and qualifies either by completing 576 hours of instruction at a board-approved apprenticeship program plus 8,000 hours of supervised installation work while registered as an Idaho apprentice, or by documenting 16,000 hours of supervised HVAC installation work, and in both cases must pass the PSI-administered journeyman exam ($75) within a year of applying; the license costs $150 and renews for $75 every three years. DOPL also issues Specialty Journeyman and Limited Heating Specialty Journeyman certificates for hearth appliances, oil furnaces and gas piping. The HVAC board's FAQ states that Idaho has no reciprocal licensing agreement for HVAC. An out-of-state journeyman can instead use Idaho's universal licensure statute (Idaho Code 67-9409), under which the board must license a person holding a current, unrestricted license elsewhere who demonstrates competency, but may still require the Idaho exam; the HVAC application form itself offers no endorsement box, so applicants should contact DOPL before filing. EPA Section 608 certification is required nationwide to handle refrigerants.
Why Missouri has nothing to transfer

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.
