Indiana to Iowa: master HVAC technician license reciprocity
Indiana does not issue a statewide master 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 master or HVAC contractor (all states): direct admission to the Iowa master exam
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
Iowa has no master-level HVAC reciprocity with any state. An applicant who was previously licensed as a master in the applicable discipline in another state or local jurisdiction is admitted to the Iowa master HVAC/refrigeration exam without having to hold an Iowa journeyperson license first (Iowa Code 105.18(2)(c); 481 IAC 429.6(3)(i)); the applicant files the $35 exam approval application, pays Kirkwood's exam fee ($95 as listed on the master page), passes with 75%, and then files the post-examination licensure application with a prorated three-year fee ($240 for a full term). An applicant who has established Iowa residency may instead apply for licensure by verification under Iowa Code 272C.12 and 481 IAC 430.4, but the board still requires proof of passing the applicable Iowa licensing examination and can issue only a temporary license until then. To contract independently the master (or the firm employing the master) must also obtain the Contractor license and DIAL contractor registration ($250 plus $150 for a full term, 30% discount when bought with the master license in one transaction), with $500,000 liability insurance, a $5,000 surety bond, and for out-of-state contractors a $25,000 bond under chapter 91C; the board's reciprocity form states there is no reciprocity for contractor licenses.
Contractor license fees, insurance and bond are listed as optional requirements because they apply only to a master who contracts independently. The Kirkwood exam fee is quoted from DIAL's master page ($95); the journey page lists $99. 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 master HVAC technicians
Iowa master HVAC technician · “Master HVAC-Refrigeration”
Statewide license
Issued by Iowa Plumbing and Mechanical Systems Board, Department of Inspections, Appeals, and Licensing (DIAL)
Iowa's highest person-held HVAC credential is the Master HVAC-Refrigeration license issued by the Plumbing and Mechanical Systems Board (DIAL); a Master Mechanical license, which adds sheet metal and hydronic work, is issued to anyone who passes both the master HVAC-refrigeration and master hydronic exams. A new master applicant must have previously been a licensed journeyperson in the discipline with at least two years of journey-level experience, or have been licensed as a master in the discipline in another state or local jurisdiction, and must pass the Iowa master exam (75%) through Kirkwood Community College. The separate Contractor license is a business credential: a sole proprietor or firm that contracts for HVAC work must hold or employ a master in each discipline, carry $500,000 liability insurance and a $5,000 surety bond (out-of-state contractors add a $25,000 chapter 91C bond), and register as a contractor with DIAL on the same application. Iowa has no HVAC reciprocity agreement with any state and states plainly that there is no reciprocity for contractor licenses. An out-of-state master may sit the Iowa master exam directly on the strength of the out-of-state license; Iowa residents may use licensure by verification but the board still requires the Iowa exam. Licenses run three years and require eight hours of continuing education per term.
Why Indiana has nothing to transfer
Indiana master HVAC technician
Licensed by cities and counties
Indiana has no statewide master HVAC, mechanical contractor or HVAC contractor license and no state HVAC board; the Indiana Professional Licensing Agency's list of regulated professions contains no heating, air conditioning or refrigeration trade, and Indianapolis's exam information states that licensing is at the discretion of each municipality. The master-level credential exists only locally and under varying names: Indianapolis/Marion County licenses Heating and Cooling Contractors (Air Conditioning A, B, D, Refrigeration and High Pressure Steam) whose craft license holder passed the Prov exam, Allen County (Fort Wayne) issues an HVAC Supervisors License (Air Conditioning A or B, Sheet Metal C), Evansville licenses Master Heating, Ventilating and Air Conditioner Installers and Master Refrigeration Installers by local examination, South Bend registers HVAC contractors on proof of a passing ICC National Standard Master Mechanical exam, and Terre Haute issues a Mechanical license to contractors employing a NATE, HVAC Excellence, RSES, Experior or Indianapolis-certified person. An out-of-state master HVAC or mechanical contractor license carries no state-level recognition in Indiana. Indianapolis is the only jurisdiction with a published reciprocity procedure, and it turns on the exam rather than the state: a license earned on a Prometric/Experior or Prov exam with a 70% score, certified by the issuing agency, can be accepted by the Board of Heating and Cooling Examiners. Elsewhere a master must apply in each city or county where they will pull permits, which in practice means holding an ICC or Prov national exam score or passing the local exam, then meeting that jurisdiction's bond and insurance rules. EPA Section 608 certification is required for refrigerant work in every jurisdiction.
How local licensing works in Indiana
How local licensing works. Indiana regulates plumbers at the state level but has never created a state HVAC or mechanical contractor license. Each city or county building department decides whether and how to license HVAC contractors and master-level installers, and there is no statewide portability rule. Prov (Indianapolis) and ICC/Prometric (South Bend, Terre Haute) national exams are the most portable credentials inside the state.
Indianapolis / Marion County. The Department of Business and Neighborhood Services licenses Heating and Cooling Contractors in five types: Air Conditioning A (unrestricted), Air Conditioning B (25 tons cooling / 500,000 BTU heating, boilers to 15 psig steam), Air Conditioning D (5 tons / 300,000 BTU), Refrigeration, and High Pressure Steam. A craft license holder submits an exam packet ten business days before the monthly Board of Heating and Cooling Examiners meeting: application, resume, employer letters verifying five years of HVACR experience (education may substitute in part), three industry reference letters, EPA certification card, driver's license; after a board interview the applicant sits the Prov exam and needs 70%. The business then files a $5,000 surety bond (obligee the Consolidated City of Indianapolis, expiring 12/31/2027), a $500,000/$100,000 (or $500,000 combined) liability certificate naming the City-County as additional insured, and workers' compensation proof. 2026 fees: new license holder $377 (Jan-Jun) or $283 (Jul-Dec), new business license $247 or $185 (none for sole proprietors), renewals $247 each; licenses expire December 31 of odd-numbered years. Reciprocity: the board may accept a comparable license from any municipality or government agency if the issuing agency certifies directly to the Department that the license is current and unsuspended, the license was issued on a standardized Prometric (formerly Thomson Prometric / Experior / Block) or Prov exam passed with at least 70%, and the vendor verifies the exam is equivalent to the Indianapolis exam; the applicant still documents five years of experience, three references and EPA certification, appears before the board, and then licenses with bond, insurance and fees.
Fort Wayne / Allen County. The Building Department's HVAC Supervisors License (Air Conditioning A without BTU limit, Air Conditioning B up to 500,000 BTU heating and 25 tons cooling, or Sheet Metal C) requires four years and 7,000 hours as a journeyman in the same line of work (or eight years and 14,000 hours of documented OJT plus 30 days as a licensed journeyman) and a passing examination administered by the Building Commissioner or an approved testing facility; hydronic and low-temperature refrigeration work is reserved to Non-Sanitary Piping licensees. The supervisor qualifies an HVAC Contractors Business Registration ($90; supervisor license $25). Section H grants reciprocity subject to the trade's guidelines and minimum qualifications, and allows the Building Commissioner to grant reciprocity at his discretion to applicants who present the necessary credentials.
Evansville. The Building Commission licenses Master Heating, Ventilating and Air Conditioner Installers (forced-air heating, air conditioning up to five tons with field piping or fifteen tons packaged, ventilation, ductwork and sheet metal; boilers and steam or hot-water systems require the Master Steam Fitter license) and Master Refrigeration Installers. Applicants prove four years of experience with three notarized letters on letterhead (EMC 5.70.060), are approved to test by the Board of Examiners of HVAC, Steam Fitters, and Refrigeration Installers, sit the exam through Ivy Tech and must score 75% on each part of the master mechanical, sheet metal, ventilation or refrigeration exam, then receive a provisional license on paying the $300 fee and providing insurance and the $25,000 surety bond required by EMC 5.70.070; renewal is $125 ($225 for two years) with board-set continuing education. The ordinance notes the master HVAC license does not permit air conditioning work without EPA certification.
South Bend. The Building Department registers HVAC contractors (including refrigeration and hood installers) after review of an application showing at least 21 years of age, journeyman and contractor experience (education may substitute for part of four years), and a passing score of at least 70% on the ICC National Standard Master Mechanical exam (F29-N) via Pearson Vue or Prometric or a comparable nationally recognized exam approved by the Board; a $5,000 surety bond naming the City of South Bend/St. Joseph County, workers' compensation proof, a $50 application review fee and $125 annual registration are required.
Terre Haute. The Engineering Department's Mechanical license is issued to a contractor that employs at least one full-time employee certified by NATE, HVAC Excellence, RSES, Experior Assessment, the City of Indianapolis HVAC Air Conditioning Class A, or an equivalent, with a $10,000 bond ($25,000 for right-of-way work), $500,000 general liability ($1,000,000 for right-of-way work) and workers' compensation or a WCE-1 exemption; $350 original registration, $175 annual renewal.
Out-of-state holders. Only Indianapolis publishes a reciprocity procedure, and it accepts a license from any jurisdiction (municipal or state) that was earned on an equivalent Prometric/Experior or Prov exam, subject to board approval. Allen County has a discretionary reciprocity clause; South Bend and Terre Haute accept national exam scores and industry certifications regardless of where they were earned; Evansville requires its own examination. Expect to license separately in each jurisdiction and to meet each one's bond and insurance rules.
