Tennessee to Michigan: master HVAC technician license reciprocity

No credit· Start overVerified September 15, 2026· 8 sources

Tennessee does not issue a statewide master HVAC technician license, so there is nothing to transfer. Here is Michigan'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 or mechanical contractor (all states; Michigan has no reciprocity)

Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.

Michigan has no reciprocity agreement with any state and no endorsement route; LARA's Out-of-State License Verification form states that Michigan 'does not reciprocate with any other state for licensing' and that the applicant is 'required to take and pass an examination'. An out-of-state licensee files the standard Application for Mechanical Contractor Examination & Licensing with the $300 fee, selects the classifications wanted, and documents 3 years or 6,000 hours of experience in each classification with statements signed under penalty of perjury by each present or former mechanical contractor employer; applicants with out-of-state experience must be approved by LARA before PSI will let them schedule. The applicant then passes each classification exam at PSI within one year of eligibility (HVAC Equipment: 150 questions, open book, 3 hours, $100; other classifications: 55 questions, 60 minutes, $50; 75% to pass, unlimited retakes within the year). There is no separate law or business exam, but every exam includes questions on the Skilled Trades Regulation Act and the Stille-DeRossett-Hale Single State Construction Code Act. The license runs on a 3-year cycle expiring August 31 and the fee is prorated for mid-cycle applicants.

Whether experience documented by an out-of-state employer that is not a Michigan 'contractor of record' is accepted as the 'equivalent experience acceptable to the board' under MCL 339.5807(1)(a) is decided by LARA case by case; the out-of-state form only says such applicants must be approved to sit. Exam fees listed are per classification; an applicant seeking several classifications pays each.

What you'll do to get licensed in Michigan

  1. 1License fee. Pay the license or certificate fee ($300). Mechanical contractor application and license fee for the 3-year cycle ($100 per year under MCL 339.5813, prorated for mid-cycle applicants; waived for eligible veterans); additional classifications $300/$200/$100 by cycle year.
  2. 2Trade exam. Pass the destination's trade exam. PSI Michigan Mechanical Contractor examination for each classification sought (HVAC Equipment: 150 questions, open book, 3 hours; Refrigeration, Ductwork, Hydronic and specialty exams: 55 questions, 60 minutes, open book; heating and refrigeration/air conditioning service exams: 55 questions, closed book); 75% to pass.
  3. 3Exam fee. Pay the exam fee ($100). PSI exam fee for the HVAC Equipment (includes ductwork and gas piping) classification; non-refundable, valid one year.
  4. 4Exam fee. Pay the exam fee ($50). PSI exam fee for each other classification (hydronic, ductwork, refrigeration, limited/unlimited heating service, limited/unlimited refrigeration and air conditioning service, fire suppression, specialty).
  5. 5Other. EPA Section 608 technician certification (Type I/II/III/Universal) to handle refrigerants; federal, does not expire. LARA's mechanical pages are silent on it; it is a federal requirement, not a Michigan licensing prerequisite.

Published fees on this path total $450, excluding exam-vendor fees, bonds, and insurance.

How Michigan licenses master HVAC technicians

Statewide license

Verified September 15, 2026· 6 sources

Issued by Michigan Department of Licensing and Regulatory Affairs (LARA), Bureau of Construction Codes, Board of Mechanical Rules

Michigan's HVAC credential is the Mechanical Contractor license issued by LARA's Bureau of Construction Codes under Article 8 of the Skilled Trades Regulation Act (2016 PA 407). Although called a contractor license, it is issued to an individual who qualifies by examination, so this file treats it as the master level: a business performs mechanical work by designating a licensed individual as its contractor of record (MCL 339.5809, 339.5815). The license is classified; an HVAC business typically holds HVAC Equipment (which includes ductwork and gas piping), Refrigeration and the heating and refrigeration/air conditioning service classifications. For each classification the applicant documents 3 years or 6,000 hours of experience with statements signed under penalty of perjury by each employing contractor of record (a 2-year HVAC program may be credited up to 1 year or 2,000 hours), is approved by LARA, and passes the PSI exam for that classification (75% to pass; the HVAC Equipment exam is 150 questions, open book, 3 hours, $100; other classification exams are 55 questions, 60 minutes, $50). The license fee is $300 for the 3-year cycle ($100 per year, prorated), licenses expire August 31 every third year, and municipalities may not impose their own licensing (MCL 339.5811). Michigan has no reciprocity with any state and no licensure by endorsement: LARA's out-of-state form states that Michigan 'does not reciprocate with any other state for licensing' and that out-of-state applicants must be approved to sit for the examination, so an out-of-state HVAC or mechanical contractor's experience counts toward eligibility but the Michigan exams must be passed. 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

Verified September 15, 2026· 16 sources

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.
