Tennessee to Wisconsin: master HVAC technician license reciprocity
Tennessee 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: Form 3122 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 wherever it was earned, documented on the Form 3122T experience table with witness signatures, 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. DSPS lists a 4-year renewal cycle for the qualifier; SPS 305 Table 305.07 still shows 2 years.

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 $100 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 Tennessee has nothing to transfer
Tennessee master HVAC technician
Licensed by cities and counties
Issued by Local code enforcement offices (Nashville, Memphis/Shelby County, Chattanooga, Knoxville and other exempt jurisdictions); the state issues only the CMC / CMC-C contractor license to businesses
Tennessee does not issue a master HVAC license. The state-level HVAC credential is a contractor license with the CMC (full mechanical: plumbing and HVAC) or CMC-C (HVAC/refrigeration) classification from the Board for Licensing Contractors, which is issued to a business that names a qualifying agent and is required for any project of $25,000 or more. The qualifying agent passes the Tennessee Business & Law exam and the CMC or CMC-C trade exam (Prov from July 1, 2026; CMC candidates need Board pre-approval, $50), and the business files a reviewed or audited financial statement (or, from July 1, 2026, a surety bond of at least half the requested limit) that sets its monetary limit, proves general liability and workers' compensation insurance, and pays $250 ($200 biennial renewal). The Board's trade-exam-waiver agreements let a contractor licensed in Alabama (HVAC), Louisiana (mechanical), Mississippi (mechanical), Ohio (HVAC), South Carolina (HVAC) or West Virginia (mechanical) skip the trade exam but not the Business & Law exam or any other requirement; North Carolina's and NASCLA's waivers do not cover HVAC. Master-level licenses issued to individuals exist only locally: Nashville's Master Mechanical (six years) and HVAC&R (four years) certificates, Memphis/Shelby County's First-Class and Third-Class Mechanical Contractor licenses, and Chattanooga's Master Mechanical Contractor license. A master HVAC license from another state has no state-level recognition in Tennessee; its holder either registers a business for the CMC-C license or applies for the local master card where they will work. EPA Section 608 certification is required federally to handle refrigerants.
How local licensing works in Tennessee
State contractor route (CMC / CMC-C). Required statewide for projects of $25,000 or more and accepted by the cities as a substitute for their own master cards for permit purposes (Nashville registers CMC/CMC-C firms for $100 with a $40,000 bond and $300,000 liability certificate; Memphis/Shelby County registers state mechanical licensees for $150). Requirements: Business & Law exam plus the CMC-C or CMC trade exam ($50 pre-approval for CMC), $250 application fee, reviewed or audited financial statement or a surety bond of at least 50% of the monetary limit (from July 1, 2026), general liability and workers' compensation insurance. Trade-exam waiver, on verification by the other board that the qualifying agent passed a comparable exam: Alabama HVAC (CMC-C), Louisiana Mechanical (CMC), Mississippi Mechanical (CMC), Ohio HVAC (CMC-C), South Carolina HVAC (CMC-C), West Virginia Mechanical (CMC). The Board stresses the waiver applies only to the trade exam, cannot be used by applicants with discipline, open complaints or felony convictions, and does not allow another state's license to be used in Tennessee.
Nashville (Davidson County). The Board of Mechanical, Plumbing and Electrical Examiners and Appeals issues the Master Mechanical certificate (six years' experience) and HVAC&R certificate (four years); a mechanical engineering degree may substitute. The application asks for licenses held in other cities or states, employer confirmations and a recommendation letter; the Chief Mechanical Inspector approves, Prov administers the exam (70% to pass, 30-day retest wait). The certificate holder then registers the firm as a Metropolitan Mechanical Gas Contractor with a Davidson County business license, $40,000 permit bond and $300,000 liability certificate. No exam waiver for out-of-state licenses is published.
Memphis and Shelby County. First-Class Mechanical Contractor (age 21, 4 years of full-time installation or design experience, unlimited scope) and Third-Class Mechanical Contractor (2 years, equipment up to 15 tons or 15 hp) after a written exam set by the Mechanical/Gas Code Board; $150 registration, $110 annual renewal, licenses expire December 31, $25,000 continuous permit bond. The mechanical code has no reciprocity provision for mechanical contractors.
Chattanooga. Master Mechanical Contractor license from the Board of Mechanical Examiners: three or more years as a Journeyman Mechanic Class 1 or 2, or a current or previously held unrevoked Master Mechanical Contractor or equivalent license from Chattanooga or any other governmental agency, or a Tennessee PE license, or acceptable education and experience; $415 per two-year cycle including the exam fee. A license from elsewhere establishes eligibility for the exam but is not stated to waive it.
Knoxville. Permits are pulled under a State Contractor Registration (CMC/CMC-C) or the other registration types on the city's permit page; the city's own mechanical license classes and fees could not be confirmed from an official page, so contact Plans Review & Inspections (865-215-4311).
Out-of-state holders. The only published recognition in Tennessee is the state Board's trade-exam waiver for contractors from AL, LA, MS, OH, SC and WV, which still requires the Business & Law exam and a full contractor application. The local master cards in Nashville, Memphis and Chattanooga treat an out-of-state master license as evidence of experience or exam eligibility, not as a substitute for their own examinations.
