Mississippi to Idaho: master HVAC technician license reciprocity
Mississippi 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 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. The board's published materials do not say whether any part of the exam is waived under 67-9409. The contractor application also requires an individual applicant to hold an active Idaho HVAC Journeyman license, or a business applicant to employ at least one, and the PSI contractor exam covers only the Contractor's Business and Law Reference Manual.

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). An individual applicant must already hold an active Idaho HVAC Journeyman license, or a business applying as an entity must employ at least one Idaho-licensed HVAC journeyman. 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 Mississippi has nothing to transfer
Mississippi master HVAC technician
Licensed by cities and counties
Mississippi does not issue a personal master HVAC license. The state-level HVAC credential is the Mississippi State Board of Contractors (MSBOC) contractor license: commercial 'Heat, Ventilation, A/C - HVAC' under the Mechanical classification (required on commercial jobs over $50,000; application and renewal $400, $300,000/$600,000 liability insurance, CPA-reviewed financial statement) or Residential HVAC (required for residential work over $10,000 in remodeling or $50,000 new construction; application $50, renewal $100). The license is issued to the business through a Certificate of Responsibility with a named qualifying party who passes the open-book PSI HVAC (or Residential HVAC) trade exam and the mandatory Mississippi Law and Business Management exam, so a master HVAC mechanic who only wants to work for an employer has nothing to transfer to at the state level; the personal master credential exists only in cities such as Southaven (Master Mechanical, $100, which itself requires an active MSBOC license, a $10,000 bond and liability insurance) and Gulfport (Mechanical/HVAC contractor license issued to the qualifying party, $100). MSBOC waives its HVAC trade exam, for $50 per exam, for qualifying parties who have held a license for at least one year with the Alabama Board of Heating, Air Conditioning and Refrigeration Contractors, the Alabama General Contractors Board, the Louisiana State Licensing Board for Contractors, the Ohio Construction Industry Licensing Board (HVAC or Refrigeration), the South Carolina Residential Builders Commission (Residential HVAC) or the Tennessee Board for Licensing Contractors, provided the license was obtained by that board's exam and there has been no disciplinary action in the period stated in each agreement; the Business and Law exam is never waived. EPA Section 608 certification is a separate federal requirement.
How local licensing works in Mississippi
State contractor license (business). MSBOC issues commercial and residential contractor licenses to companies through a Certificate of Responsibility. The commercial HVAC classification ('Heat, Ventilation, A/C - HVAC', with Ductwork, Refrigeration and Boiler specialties) requires the PSI open-book HVAC trade exam and the Mississippi Law and Business Management exam taken by the qualifying party (owner, officer or responsible managing employee), a $400 application fee ($400 annual renewal, $100 per additional classification), general liability insurance of $300,000 per occurrence / $600,000 aggregate naming MSBOC, and a CPA-reviewed financial statement showing net worth of $50,000 for a major classification or $20,000 for a specialty. Residential HVAC and Residential Mechanical (HVAC plus plumbing) licenses require the Residential HVAC (and Plumbing) exam and the Law and Business exam, a $50 application fee ($100 per additional classification, $100 renewal), proof of liability insurance with no minimum, three reference letters and documented experience in the classification.
MSBOC exam waivers for out-of-state qualifying parties. Reciprocity waives the trade exam only ($50 per exam waived, plus a $25 verification fee) after the origin board completes MSBOC's Reciprocity Verification Form; the applicant must have held the origin license for one year and passed that board's exam. HVAC waivers are available for the Alabama Heating and Air board (current license, Alabama exam), the Alabama General Contractors Board (HVAC can be waived; no discipline in the last year), Louisiana (HVAC can be waived but not mechanical or plumbing; the formal agreement ended but MSBOC continues to recognize Louisiana scores), Ohio CILB (HVAC and Refrigeration; no discipline in the last year), the South Carolina Residential Builders Commission (Residential HVAC; no discipline in three years) and Tennessee (all exams, the only state whose mechanical and plumbing exams are waived; no discipline in the last year). Arkansas, Florida, Georgia, North Carolina and the South Carolina Contractors Licensing Board agreements do not cover HVAC. Everyone takes the Mississippi Law and Business Management exam.
Southaven. Master Mechanical license ($100) for the license qualifier: application, photo ID, certificate of liability insurance, $10,000 surety bond in favor of the city, an active MSBOC contractor's license certificate and the company EIN. An out-of-state contractor without an MSBOC license must instead provide a letter of good standing from a municipality where its license is active and may not take residential projects or commercial projects over $50,000; the city defers to MSBOC on reciprocity.
Gulfport. Mechanical/HVAC contractor license ($100, waived with an MSBOC Certificate of Responsibility) issued in the name of the qualifying party: notarized application, current MSBOC license if held, five reference letters (waived with an MSBOC license), $100,000/$300,000 public liability insurance naming the city, home-jurisdiction privilege license and photo ID.
Out-of-state holders. A master HVAC licensee from another state who wants to contract in Mississippi applies to MSBOC as the qualifying party of a business, uses the exam waiver if the origin board is on the list, and then registers with each city; a master who only wants employment needs no state license and, in most cities, no personal card.
