Missouri to Iowa: journeyman HVAC technician license reciprocity

No credit· Start overVerified September 15, 2026· 13 sources

Missouri does not issue a statewide journeyman HVAC technician license, so there is nothing to transfer. Here is Iowa'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.

Out-of-state journeyman (all states): Iowa exam required, licensure by verification for Iowa residents

Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.

Iowa has no reciprocity agreement for HVAC-refrigeration or mechanical licenses with any state, so every out-of-state journeyman follows the same path. An applicant who has established Iowa residency may apply for licensure by verification under Iowa Code 272C.12 and 481 IAC 430.4: the origin state sends a verification form directly to the board confirming the license is in good standing and was earned by meeting that state's experience requirements and exam, and the applicant provides proof of residency and a criminal history statement, but the board also requires proof of passing the applicable Iowa licensing examination and may issue a temporary license while the applicant takes it. A non-resident applies through the normal exam route: the $35 exam approval application, the Kirkwood-administered journeyperson HVAC/refrigeration exam ($99 per attempt, 75% to pass, approval valid one year), then the post-examination licensure application and a prorated three-year license fee ($180 for a full term). Exam eligibility requires either the U.S. DOL apprenticeship certificate of completion or a master-level license in the same discipline from another jurisdiction; DIAL's pages do not say that an out-of-state journeyman license alone substitutes for the DOL certificate. An Iowa resident arriving from a jurisdiction that did not license HVAC work may instead substitute three years of full-time experience in the last four years under 481 IAC 430.5. EPA Section 608 certification is federal and applies regardless of the Iowa license.

DIAL's journey page lists the Kirkwood exam fee as $99 per attempt while the master page lists $95; both are quoted as published. Whether the board treats an out-of-state journeyman license (without a DOL certificate) as satisfying the apprenticeship requirement for a non-resident was not confirmed from an official page; 481 IAC 430.4 makes the verification route residency-dependent. Timeline reflects up to two weeks for exam approval plus up to six weeks for post-exam application review, excluding exam scheduling.

How Iowa licenses journeyman HVAC technicians

Iowa journeyman HVAC technician · “Journeyperson HVAC-Refrigeration”

Statewide license

Verified September 15, 2026· 6 sources

Issued by Iowa Plumbing and Mechanical Systems Board, Department of Inspections, Appeals, and Licensing (DIAL)

Iowa issues statewide person-held HVAC licenses through the Plumbing and Mechanical Systems Board (PMSB), now housed in the Department of Inspections, Appeals, and Licensing (DIAL); Iowa Code chapter 105 preempts all city and county HVAC licensing. The journey-level credential is the Journeyperson HVAC-Refrigeration license, which covers HVAC and refrigeration work; a broader Journeyperson Mechanical license also covers sheet metal and hydronic work and is issued to anyone who passes both the HVAC-refrigeration and hydronic journeyperson exams. A new applicant needs four years as an apprentice in a U.S. Department of Labor-registered apprenticeship and must pass the Iowa journeyperson exam (75% to pass) administered through Kirkwood Community College. Iowa has no HVAC reciprocity agreement with any state; its only reciprocity agreement is with South Dakota for plumbers. An out-of-state journeyman who moves to Iowa can use licensure by verification, but the board still requires the Iowa discipline exam; a non-resident with only a journeyman license must document the DOL apprenticeship and pass the exam, while a non-resident holding a master-level HVAC license from another jurisdiction may sit the journeyperson exam without the apprenticeship. A limited no-exam Service Technician HVAC Specialty license exists for NATE-certified or trained technicians who only service appliances from the shutoff valve onward. Licenses run on a three-year cycle ending June 30, 2029, and renewal requires eight hours of continuing education per term.

Why Missouri has nothing to transfer

Missouri journeyman HVAC technician

Licensed by cities and counties

Verified September 15, 2026· 12 sources

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.
