Kansas to Connecticut: master HVAC technician license reciprocity
Kansas does not issue a statewide master HVAC technician license, so there is nothing to transfer. Here is Connecticut'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.
Contractor (S-1) by equivalent out-of-state license (all states)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
A master HVAC technician or HVAC/mechanical contractor licensed in any other state applies under DCP's 'Heating Contractor - Equivalent Out of State License' path. DCP reviews a single out-of-state license for equivalency to the S-1: it must have required 576 classroom hours with a curriculum matching Exhibit A and 12,000 on-the-job hours (8,000 as an apprentice plus two years as a licensed journeyperson); the limited D-1 class needs 8,000 OJT and 432 classroom hours and the B-1 needs 6,000 and 288. The applicant submits a copy of the license, an official license verification, the laws and regulations that set the requirements met to obtain it, and the scope of work for that license, with the non-refundable $150 application fee. If approved, the applicant must pass both the S-1 trade exam and the Business and Law exam through PSI ($59 per portion) and then pay the $150 initial license fee; the out-of-state license does not waive either exam because Connecticut has no reciprocal agreements. An applicant whose license is not found equivalent must document the classroom and OJT hours directly under the equivalent experience and training path, where out-of-state journeyman service counts if DCP finds it comparable (CGS 20-334a(a)(1)(A)).
The out-of-state license page does not restate the exam requirement; it follows from the Heating, Cooling and Sheet Metal Work Licenses page, CGS 20-334a(a)(1)(A) and the PSI bulletin, which states that all contractors must pass a Business and Law examination and a trade examination. CGS 20-333a allows licensure without examination only where the other state reciprocates for Connecticut licensees, and DCP states no such agreements exist. Whether DCP treats an out-of-state 'master HVAC' license (rather than a contractor license) as the S-1 equivalent depends on the hour and curriculum comparison; DCP publishes no list of accepted titles. EPA Section 608 is not mentioned on the DCP pages but applies federally to anyone handling refrigerants.

How Connecticut licenses master HVAC technicians
Connecticut master HVAC technician · “S-1 Unlimited Heating, Piping and Cooling Contractor”
Statewide license
Connecticut has no license titled 'master HVAC'; the top-tier personal credential is the S-1 Unlimited Heating, Piping and Cooling Contractor, issued by DCP to an individual (DCP licenses individuals, not companies) and permitting all heating, piping and cooling work under CGS 20-330, pulling permits and contracting with the public. Limited contractor classes cover narrower scopes, chiefly the D-1 Limited Warm Air, Air Conditioning and Refrigeration Contractor and the B-1 Limited Gas and Oil Burner Contractor. A new S-1 applicant needs 576 classroom hours matching DCP's Exhibit A curriculum and 12,000 OJT hours (8,000 as an apprentice plus two years, 4,000 hours, working as a licensed journeyperson), reachable through two years as a Connecticut journeyperson, equivalent experience and training, or an equivalent out-of-state license, and must pass both the PSI S-1 trade exam (80 questions, 3 hours, 70%) and the Business and Law exam (50 questions, 2 hours, 70%). CGS 20-334a(a)(1) expressly allows journeyman service performed outside Connecticut to count if DCP finds it comparable. DCP states that Connecticut does not have reciprocal agreements with any other jurisdiction. Fees are a $150 application fee, $59 per exam portion and a $150 initial license fee; licenses expire every August 31 and renew for $150.
Why Kansas has nothing to transfer
Kansas master HVAC technician
Licensed by cities and counties
Kansas does not issue a master HVAC license; the master credential exists only at the county and city level under the framework in K.S.A. 12-1540 to 12-1544. State law requires a master heating, ventilation and air conditioning mechanic certificate to rest on a journeyman certificate held for at least two years or four years of field experience, plus a 75% score on an ICC, IAPMO or Prometric standard master mechanical exam, and makes a certificate earned on those exams valid proof of competency in every Kansas jurisdiction that licenses HVAC mechanics without additional examination. Sedgwick County/Wichita (MABCD) issues master mechanical certificates ($35) on ICC K9L/556 or the IAPMO master exam; Topeka licenses mechanical masters on the Standard Unlimited Air Conditioning Master exam; Lawrence certifies master mechanicals with four years of field experience or two as a journeyman ($20); Kansas City, Kansas requires mechanical masters to hold a master's license from Building Inspections; and Johnson County uses the ICC Standard Master Mechanical exam (556/KGL) to qualify the individual behind a Class DM mechanical contractor license ($100 application plus $225 license fee). None of these jurisdictions has a reciprocity agreement with another state (MABCD states it does not reciprocate with state testing), so an out-of-state master HVAC license transfers nothing except, in practice, a qualifying ICC, IAPMO or Prometric exam score that the applicant may already hold. EPA Section 608 certification is a separate federal requirement.
How local licensing works in Kansas
How local licensing works. K.S.A. 12-1540 defines a master heating, ventilation and air conditioning mechanic as a person qualified to plan, lay out and supervise the installation and repair of mechanical HVAC systems, and K.S.A. 12-1542 lets a county or city issue a master certificate of competency only to someone who has held a journeyman certificate for two years or has four years of field experience and scores 75% on the ICC, IAPMO or Prometric standard master exam (K.S.A. 12-1541). That certificate is valid proof of competency for licensure in any other licensing county or city without retesting; a license based on an alternative local exam is good only in the issuing jurisdiction (K.S.A. 12-1543). Each jurisdiction charges its own fee and requires 12 hours of continuing education biennially or 6 annually. Contracting is licensed separately by each jurisdiction and generally requires a master-level qualifying individual.
Sedgwick County and Wichita (MABCD). Mechanical master certificate ($35): must hold a mechanical journeyman certificate plus two years of field experience as a journeyman, or have four years of field experience, and score 75% on ICC K9L/556 Master Mechanical or the IAPMO master exam. MABCD 'does not reciprocate with state testing'. Contractors are licensed separately by MABCD.
Johnson County. Does not license individuals. The master-level credential is the qualifying individual of a Class DM (HVAC, mechanical and refrigeration) contractor license, who must present a verifiable ICC Standard Master Mechanical (556/KGL) score of 75% or higher; the contractor pays $100 application plus $225 per license type ($225 annual renewal, $75 late) and carries general liability and workers' compensation insurance.
Kansas City, Kansas (Unified Government). Trade masters, including mechanical, must carry a master's license from Building Inspections, obtained through Prometric master testing; experience rules and fees for mechanical are not published on the page.
Topeka. Mechanical masters must meet the K.S.A. 12-1542 requirements and show a 75% score on the Standard Unlimited Air Conditioning Master exam from Block, NIA-Block, Experior, Thomson-Prometric or Prometric, with a notarized time-in-trade form and a $50 trade board review fee; six hours of continuing education a year (three in the trade), licenses expire December 14. TMC 5.63.080 lets the city register holders of trade licenses from other jurisdictions with equivalent requirements. A master must be the designated master for a licensed contractor to pull permits.
Lawrence. Master Mechanical license ($20) after certification: four years of practical field experience or two years as a journeyman (an engineering degree substitutes for 2.5 years and a vocational-technical program for one year), $50 exam application fee, 75% passing score, six hours of continuing education a year; a master may become a mechanical contractor under Chapter V, Article 15.
Out-of-state holders. No Kansas jurisdiction publishes reciprocity for another state's master HVAC license. The practical route is to present or earn a passing ICC, IAPMO or Prometric master mechanical score (Standard Master Mechanical 556/KGL is accepted by Johnson County and MABCD), document the required experience, and apply in each jurisdiction, then obtain the local contractor license if the master will pull permits.
