Louisiana to Idaho: master HVAC technician license reciprocity
Louisiana does not issue a statewide master 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 contractors (all states)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
With no reciprocity agreements, every out-of-state HVAC contractor or master is treated the same. Idaho Code 67-9409 obliges the HVAC board to license a person who holds a current, valid and unrestricted license in another state and demonstrates competency, on the standard application, fees and background checks, but lets the board require all or part of its examination; the board's rules require every contractor applicant to pass the board-designated exam and post a $2,000 bond, and DOPL publishes no HVAC-specific endorsement procedure. The realistic path is therefore the standard contractor application ($35), the PSI contractor exam ($75), the $2,000 compliance bond and the $225 license fee, with the out-of-state license and experience submitted as supporting evidence of competency.
Idaho's contractor exam covers business and law material (the DOPL Contractors' Business and Law Reference Manual is the allowed reference), so it is recorded as the trade exam rather than a separate law exam. Idaho Code 54-5013 sets a 24-month certificate term while DOPL's fee table shows a 3-year term for journeyman and contractor licenses; the fee table is the current practice. Whether the board waives any part of the exam under 67-9409 was not confirmed from an official page.

How Idaho licenses master HVAC technicians
Idaho master HVAC technician · “HVAC Contractor”
Statewide license
Idaho has no master HVAC title; its highest credential is the HVAC Contractor certificate of competency, which is issued as a card in the name of the individual who passes the board's contractor examination and is therefore mapped here to the master level (an HVAC business must hold or employ a certificate holder, and Specialty Contractor and Limited Heating Specialty Contractor certificates cover gas piping, hearth appliances and oil furnaces). The applicant pays a $35 application fee, passes the PSI-administered HVAC contractor exam ($75, using the DOPL Contractors' Business and Law Reference Manual as a reference), provides a $2,000 compliance bond, and pays the $225 license fee; the certificate renews for $150 every three years. Idaho's HVAC board states that it has no reciprocal licensing agreement. A contractor licensed in another state may apply under Idaho's universal licensure statute (Idaho Code 67-9409), which requires the board to license a person with a current, unrestricted out-of-state license who demonstrates competency, but allows it to require the Idaho exam; since DOPL publishes no separate procedure for HVAC, applicants should expect to take the contractor exam. EPA Section 608 certification is required nationwide to handle refrigerants.
Why Louisiana has nothing to transfer
Louisiana master HVAC technician
Licensed by cities and counties
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.
