Missouri to Wisconsin: master HVAC technician license reciprocity
Missouri does not issue a statewide master HVAC technician license, so there is nothing to transfer. Here is Wisconsin'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 HVAC contractor or master (all states; no Wisconsin reciprocity)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
Wisconsin has no reciprocity or endorsement path for HVAC credentials from any state; an applicant licensed elsewhere applies for the HVAC Qualifier certification exactly as a new candidate. Out-of-state experience counts: DSPS accepts at least 1,000 hours per year for four years of experience supervising or performing the design, installation, servicing or maintenance of HVAC systems without limiting it to Wisconsin, documented on the Trades Experience Form (Form 8168) that the applicant's witnesses sign off, or four years of HVAC-related education, or a combination. The applicant applies in the LicensE portal, pays the $15 application fee and exam fee, is made eligible to test, and must pass the open-book DSPS HVAC Qualifier exam (70% passing score, 4-hour seat time, $95 at Pearson VUE) before paying the $60 certification fee. Wisconsin has no separate law or business exam for the qualifier. A business that will contract for HVAC work must also hold the HVAC Contractor registration ($15 application plus $160 registration fee), which requires no exam.
SPS 305 Table 305.02 lists a $25 examination fee, while DSPS's Pearson VUE schedule lists $95 payable to Pearson VUE for the 4-hour HVAC Qualifier exam; DSPS's trades exam page says exams at Pearson centers carry a marginally higher fee than DSPS-administered sittings. Both figures are recorded. The qualifier certification runs four years under both SPS 305 Table 305.06 and DSPS's renewal schedule.

How Wisconsin licenses master HVAC technicians
Wisconsin master HVAC technician · “HVAC Qualifier”
Statewide license
Issued by Wisconsin Department of Safety and Professional Services (DSPS), Division of Industry Services
Wisconsin's highest person-held HVAC credential is the HVAC Qualifier certification issued by DSPS under Wis. Stat. 101.178(3) and SPS 305.71, which this file treats as the master level. It is issued to an individual who documents at least 1,000 hours per year for four years of experience supervising or performing the design, installation, servicing or maintenance of HVAC systems (or four years of HVAC-related schooling, or a combination) and passes the open-book DSPS exam (70% to pass, 4 hours, $95 at Pearson VUE); the credential is renewed every four years for $60 with no continuing education. Certification is voluntary: the mandatory credential is the business-level HVAC Contractor registration, but a business that employs a qualifier is a 'certified HVAC business' that no city or village may require to obtain a local certification, license or other approval. DSPS publishes no reciprocity agreements and no licensure-by-endorsement route for HVAC qualifiers; the experience requirement is not restricted to Wisconsin, so out-of-state work counts toward eligibility, but every applicant takes the Wisconsin exam. Federal EPA Section 608 certification is separately required to handle refrigerants.
Why Missouri has nothing to transfer
Missouri master HVAC technician
Licensed by cities and counties
Missouri does not issue a master HVAC license or a statewide mechanical contractor license; the Division of Professional Registration licenses no HVAC or mechanical profession, and unlike the electrical trade there is no voluntary statewide contractor license for HVAC. The master-level credential exists only at the local level under names that vary by jurisdiction: Springfield certifies Master Mechanical craftsmen (4 years as a certified journeyman or 10 years of experience, ICC exam, $50), Kansas City issues a mechanical certificate of qualification to the supervisor who qualifies a licensed mechanical contractor (Prometric or ICC exam, $60 application, $181 four-year renewal), and St. Louis County and the City of St. Louis license mechanical contractors through their boards of examiners. An out-of-state master HVAC license carries no state-level recognition in Missouri, and none of these jurisdictions publish a reciprocity path for it; Springfield accepts an identical ICC, Prometric, Experior or Block exam score in place of retesting and Kansas City may accept a comparable exam it deems equivalent. A master arriving from another state should expect to qualify in each jurisdiction separately and then obtain that jurisdiction's mechanical contractor license to pull permits. EPA Section 608 certification is a separate federal requirement.
How local licensing works in Missouri
How local licensing works. Missouri has no state HVAC license and no statute standardizing local HVAC licensing; each city or county sets its own master, supervisor and contractor requirements.
Springfield. Building Development Services certifies Master Mechanical craftsmen: 4 years as a certified journeyman in the trade or 10 years of satisfactory experience, documented on notarized employer forms and approved by the Building and Trades board; ICC master mechanical exam through Pearson Vue (about $125), 75% to pass; certification card $50 with $50 annual renewal. 'Reciprocation' applicants submit copies of their other-state licenses and an identical-exam score of 75% or better from Prometric, Experior, Block or ICC; otherwise they test.
Kansas City. City Planning and Development licenses mechanical contractors ($55 application, $181 issuance, $181 renewal every four years) whose scope covers heating, duct and ventilation systems, refrigeration maintenance, gas piping to burners and control wiring. Every licensed contractor must employ a full-time supervisor who holds a Kansas City certificate of qualification in the mechanical trade; the certificate requires an application with notarized references and a passing score from a recognized agency such as Prometric or ICC ($60 application, first four-year certificate free, $181 renewal), and the city may accept a comparable exam from another jurisdiction if it deems it equivalent or superior.
St. Louis County. The Board of Examiners for Mechanical Licensing certifies mechanical contractors (a certified contractor list is published) and requires a licensed mechanical contractor bond and, for some applicants, a financial responsibility bond; applications and renewals go through the Accela portal. Master-level exam and experience details are not published on the pages that could be opened.
City of St. Louis. The Mechanical Contractors Board of Examiners (Ordinance 62579, City Code 25.10) reviews each applicant's qualifications for a Mechanical Contractor's license issued by the Building Division; the license is required to pull mechanical permits for boilers, furnaces, exhaust systems and ventilation. Contractors also need the city's graduated business license.
Out-of-state holders. No reciprocity or endorsement path for another state's master HVAC license was found in any of these jurisdictions. The practical route is to present an identical ICC or Prometric master mechanical score where accepted (Springfield; Kansas City case by case), document experience, and apply for the local master certificate and contractor license in each jurisdiction where work will be performed.
