Colorado to Iowa: journeyman HVAC technician license reciprocity
Colorado 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.

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 ($119 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.
The exam fee is the amount Kirkwood Community College currently charges for every Iowa plumbing and mechanical exam; DIAL's own pages still show older figures. DIAL's published materials do not say whether an out-of-state journeyman license without a DOL apprenticeship certificate satisfies the apprenticeship requirement for a non-resident; ask the board at 866-280-1521. 481 IAC 430.4 makes the verification route residency-dependent. DIAL says to allow up to two weeks for an exam approval application to be processed.

How Iowa licenses journeyman HVAC technicians
Iowa journeyman HVAC technician · “Journeyperson HVAC-Refrigeration”
Statewide license
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 Colorado has nothing to transfer
Colorado journeyman HVAC technician
Licensed by cities and counties
Colorado has no state HVAC license at any level; the Department of Regulatory Agencies licenses electricians and plumbers but no mechanical, heating, air conditioning or refrigeration trade, and the Pikes Peak Regional Building Department's exam notice states plainly that 'Colorado does NOT have a state license for the building or mechanical trades.' Journeyman-level HVAC credentials exist only where a city or regional building department issues them. Denver issues Heating and Ventilating Journeyman and Refrigeration Journeyman certificates (4 years / 7,000 hours of field experience plus the ICC F31 Journeyman Mechanical exam, $40 for three years), and the Pikes Peak Regional Building Department in Colorado Springs and El Paso County issues a Heating Mechanic IV (HVAC Service Technician) license for technicians employed by a licensed mechanical contractor. Most other Colorado jurisdictions license only the contractor and require no card for employees. An out-of-state journeyman HVAC license is not recognized by Denver, which does not reciprocate certificates from other states, or by PPRBD, which accepts no out-of-state exams; the applicant must document experience locally and pass the ICC exam each jurisdiction uses. EPA Section 608 certification is required nationwide to handle refrigerants.
How local licensing works in Colorado
How local licensing works. There is no state HVAC board; each city, county or regional building department decides whether to license mechanical workers and contractors under its own building code, and most use ICC National Standard exams administered through Pearson VUE ($100 per exam). Passing an ICC exam is not itself a license, and jurisdictions decide individually whether to honor it.
Denver. Community Planning and Development issues person-held Heating and Ventilating Journeyman and Refrigeration Journeyman certificates. Each requires 4 years (at least 7,000 hours) of field installation experience through an apprenticeship or on-the-job training, proven by notarized letters from employers or clients covering projects completed within the last 10 years, plus a passing letter for the ICC #F31 National Standard Journeyman Mechanical exam submitted within 90 days of application approval. The certificate fee is $40 and it renews every 3 years. Denver states that it 'does not accept or reciprocate contractor licenses and/or certificates from other counties or states.'
Colorado Springs and El Paso County (Pikes Peak Regional Building Department). PPRBD issues individual Heating Mechanic licenses: Heating Mechanic I (Fitter) for gas piping after 1 year of experience, and Heating Mechanic IV (HVAC Service Technician) for repairing and servicing HVAC equipment while employed by a licensed Mechanical Contractor A, B, C or D. Applicants pay a $50 application fee and a $10 annual license fee, pass the ICC National Standard Journey Mechanical exam (W31) where applicable, and hold combustible gas indicator and carbon monoxide detection instrument certificates; the Licensing Committee and Board of Review approve each application after a judicial record check. PPRBD accepts only ICC exams passed on or after January 1, 2016 and states that 'no out-of-state exams will be accepted.' Heating Mechanic IV renewal requires 6 hours of approved technical training.
Other jurisdictions. Denver's and PPRBD's pages were the only individual HVAC worker licenses verified for this entry; other Colorado jurisdictions (for example Aurora, Fort Collins, Boulder County and Jefferson County) generally license mechanical contractors only and were not checked for journeyman cards.
Out-of-state holders. Neither Denver nor PPRBD publishes a reciprocity or endorsement path for journeyman licenses from other states. An arriving journeyman should expect to document experience with notarized letters and pass the ICC journeyman mechanical exam for each jurisdiction that licenses individuals.
