Tennessee to Rhode Island: master HVAC technician license reciprocity
Tennessee does not issue a statewide master HVAC technician license, so there is nothing to transfer. Here is Rhode Island'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 master or contractor admitted to the Rhode Island Refrigeration Master exam (all states)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
A master HVAC technician or HVAC/refrigeration contractor licensed in any other state applies to DLT for the Refrigeration Master 1 (code 002) or Master 2 (code 003) examination on the Mechanical Trade application, with a copy of the out-of-state license and an official license verification, a notarized employer statement on company letterhead detailing all work experience, a copy of government ID and the $75 non-refundable fee, filed at least 15 days before the exam date. R.I. Gen. Laws § 28-27-10(3) accepts, in place of one year as a Rhode Island-licensed journeyperson, 'an affidavit or other reasonably satisfactory evidence showing the laws of another state specifying that person as a ... refrigeration/air conditioning ... master', and 260-RICR-30-15-2 § 2.12.C states that an out-of-state Master Class I refrigeration license 'will allow the applicant to be tested for the Refrigeration Master Class I Rhode Island license'; if the origin state has no Master Class I license, a notarized resume showing six years' experience, one as a contractor, accompanies the application (Master Class II: six years, three as a contractor). The master exam is not waived and must be passed with a score of 70 or better; the applicant is then invoiced for the $240 two-year Master I license fee ($96 for Master II). Unlike the electrical trade, an out-of-state master does not have to hold the Rhode Island journeyperson license first.
DLT publishes no separate business or law exam for the master license; the master exam is a single DLT-administered examination. Whether DLT accepts an out-of-state 'HVAC contractor' or 'master HVAC' title as the equivalent of a refrigeration/air-conditioning master under § 28-27-10(3) is decided on the license verification; no list of accepted titles is published. The DLT fee table lists both 'Refrigeration Master 1' and 'Contractor Master Refrigeration' at the same fees; the distinction between the two is not explained on any official page opened. A Master I who wants to contract as a firm also files the Mechanical Corporation application. Processing time is not published.

How Rhode Island licenses master HVAC technicians
Rhode Island master HVAC technician · “Refrigeration Master Class I (RM1, unlimited)”
Statewide license
Rhode Island's master-level HVAC credential is the Refrigeration Master Class I (RM1), the unlimited refrigeration/air-conditioning master license issued by DLT to an individual after passing the master examination; a Master Class I may be self-employed and, under R.I. Gen. Laws § 28-27-4, a master refrigeration contractor performs refrigeration/air conditioning work through a regular place of business personally or through employed journeypersons. The Refrigeration Master Class II (RM2) is the limited version (comfort cooling to 20 tons, product cooling to 3 tons, 1 hp freezing). A Rhode Island applicant must have held a Rhode Island Refrigeration Journeyperson I license for one year (or a Master II for one year; Master II requires three years as a Journeyperson II). Rhode Island has no reciprocity agreements and no exam waiver, but R.I. Gen. Laws § 28-27-10(3) and DLT regulation § 2.12.C allow an applicant whose out-of-state law designates them a refrigeration/air-conditioning contractor or master to sit the Rhode Island master exam directly on the strength of that license, or, where the origin state has no Master Class I license, on a notarized resume showing six years' experience including one as a contractor. Fees are a $75 application fee and a $240 two-year license fee for Master I ($96 for Master II); the DLT fee table also lists a 'Contractor Master Refrigeration' at $240 and a no-test Master Mechanical Contractor ($480) reserved for those with ten years each as Pipefitter Master I and Refrigeration Master I. Licenses renew every two years on the licensee's birthday.
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.
