Louisiana to Iowa: master HVAC technician license reciprocity

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

Louisiana 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.

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

Verified September 15, 2026· 7 sources

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.

Louisiana master HVAC technician

Licensed by cities and counties

Issued by Parish and municipal building departments (no state master license); Louisiana State Licensing Board for Contractors licenses mechanical contractors only

Louisiana does not issue a statewide master HVAC or master mechanic license. The state-level credential for HVAC work is the Louisiana State Licensing Board for Contractors (LSLBC) commercial license in the Mechanical classification (major classification 6, or subclassification 6.1 Heat, Air Conditioning, Ventilation, Duct Work and Refrigeration), mandatory for any mechanical project of $10,000 or more; it is a contractor license issued to the business (or a sole proprietor) and qualified by a natural person, the qualifying party, who passed the trade exam through PSI, so it is treated here as a business license rather than a person-held master credential. Master mechanic licenses exist only at the local level: New Orleans issues a Class 'A' Master Mechanical Contractor License ($110 per year) to an applicant who passed the ICC G29 Master Mechanical exam directly or through LSLBC state testing, carries $500,000 of general liability insurance, and is the only Class 'A' holder for the company; Jefferson Parish issues a $200 parish trade contractor license built on the state license. For the state contractor license the LSLBC waives the trade exam for any applicant who passed a comparable classification exam in any other state without waivers, exemptions or grandfathering, with no partner-state list since October 23, 2024, but the Business and Law course/exam, the financial statement and the other licensing requirements are never waived. No parish or city page reviewed publishes reciprocity for out-of-state master licenses. Federal EPA Section 608 certification applies to anyone who handles refrigerants.

How local licensing works in Louisiana

State contractor license (not a master license). Under La. R.S. 37:2150.1(16) a mechanical contractor is anyone contracting for air conditioning, refrigeration, heating, plumbing, ventilation, boiler or piping work of $10,000 or more, and the LSLBC issues the commercial license to that person or business with a Mechanical classification (or the 6.1 Heat, Air Conditioning, Ventilation, Duct Work and Refrigeration subclassification) qualified by a designated qualifying party. Applicants file the online application with a financial statement (required of all applicants), Secretary of State registration for any business entity including out-of-state companies, the online Business and Law course/exam, and the PSI trade exam for the classification (PSI has administered all LSLBC trade exams since August 5, 2025); statutory fee caps are $50 per examination, $100 license and $100 renewal, plus a surcharge of up to $400 that the board may assess on a contractor not domiciled in Louisiana. Reciprocity for the state license: R.S. 37:2153(F)(5) directs the board to waive the trade portion of the exam for an applicant licensed in a comparable classification in another state on written certification that the applicant passed that classification's exam and is in good standing, and the Executive Director's October 23, 2024 letter extends this to any state: a classification exam passed in any other state 'with no waivers, exemptions, or grandfathering in effect' is accepted for the equivalent Louisiana classification, and all previous state-to-state agreements were declared null and void. The applicant has the origin board complete the Reciprocity Request form (license status, disciplinary history, and the name, exam developer, date and score of each person who passed the trade exam) and uploads it with the application; the exam/administrative fee is still charged, and the business law requirement 'shall not be waived'. Once licensed, R.S. 37:2156.1(I) exempts the contractor and its employees from any parish or city examination or certification.

New Orleans. The Class 'A' Master Mechanical Contractor License covers air conditioning and refrigeration (and, separately, gasfitters): the applicant submits a passing ICC Official Results Report for exam G29 Master Mechanical, obtained from ICC directly or through state testing with the LSLBC, plus certificates of general liability insurance of at least $500,000 and workers' compensation naming the City as certificate holder, a photo and ID; the license costs $110 per year active or $25 inactive, with a $10 per month delinquent fee, renews from 90 days before the holder's birthday, and only one Class 'A' holder is allowed per company. The city page states no experience requirement and no reciprocity.

Jefferson Parish. A parish trade contractor license ($200 new) is issued to a license holder/qualifying party for mechanical work and lists the state license, occupational license, sales tax registration, liability insurance and workers' compensation on its checklist; air conditioning and heating equipment may be installed or replaced only under a filing by a parish-licensed mechanical contractor.

Shreveport. Requires city contractor registration for anyone performing HVAC work and the state license for work over $10,000; master testing is referred to the ICC or the LSLBC.

Baton Rouge and Lafayette. No official page describing a master mechanic license was located for East Baton Rouge Parish or Lafayette Consolidated Government.

Out-of-state holders. A master HVAC contractor from another state who wants to contract in Louisiana applies for the LSLBC commercial license with the Mechanical classification and, if the origin license was earned by a trade exam, requests the trade-exam waiver by reciprocity; the Business and Law course and financial statement are still required. City licenses such as New Orleans Class 'A' can then be obtained on the ICC G29 exam or LSLBC testing.
