Tennessee to Connecticut: journeyman HVAC technician license reciprocity

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

Tennessee does not issue a statewide journeyman 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.

Journeyperson by equivalent out-of-state license (all states)

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

An HVAC technician licensed in any other state applies under DCP's 'Heating Journeyperson - Equivalent Out of State License' path. DCP reviews one out-of-state license for equivalency: it must have required the same number of classroom hours (576 for the S-2), an equivalent classroom curriculum matching DCP's Exhibit A courses, and the same on-the-job training hours (8,000 for the S-2) as the Connecticut license applied for; the limited D-2 class needs 4,000 OJT and 432 classroom hours and the B-2 needs 2,000 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; only one license will be reviewed and the $90 application fee is non-refundable. If the license is found equivalent, DCP approves the applicant to sit the S-2 exam with PSI ($59 per portion, eligibility valid one year), and the license is issued after passing on payment of the $120 initial license fee. The out-of-state license does not waive the Connecticut exam because Connecticut has no reciprocal agreements. If the license cannot be shown equivalent, the applicant must instead document 576 classroom hours and 8,000 OJT hours with transcripts and notarized employer letters under the equivalent experience and training path.

DCP's out-of-state license page does not itself restate that the exam is required; the exam requirement follows from the Heating, Cooling and Sheet Metal Work Licenses page (every individual applicant must take an exam), CGS 20-334a(a)(2) (competency shown by the state licensure examination) and the PSI bulletin (the State determines eligibility, then the candidate tests). CGS 20-333a permits licensure without examination only where the other state reciprocates for Connecticut licensees, and DCP states no such agreements exist. Many states issue a single HVAC or refrigeration license rather than a heating-piping-cooling license with a 576-hour curriculum, so an applicant may be found equivalent only to a limited class such as the D-2. Neither DCP page mentions EPA Section 608; it is a federal requirement that applies regardless. Typical processing time is not published.

How Connecticut licenses journeyman HVAC technicians

Connecticut journeyman HVAC technician · “S-2 Unlimited Heating, Piping and Cooling Journeyperson”

Statewide license

Verified September 15, 2026· 6 sources

Issued by Connecticut Department of Consumer Protection, Occupational and Professional Licensing (Heating, Piping, Cooling and Sheet Metal Work Examining Board)

Connecticut licenses HVAC work statewide through the Department of Consumer Protection (DCP) as 'heating, piping and cooling' work; the journeyman-level credential is the S-2 Unlimited Heating, Piping and Cooling Journeyperson, which covers all heating, piping and cooling work defined in CGS 20-330 while employed by a licensed contractor. Narrower journeyperson classes exist for technicians whose experience is limited to part of the trade, chiefly the D-2 Limited Warm Air, Air Conditioning and Refrigeration Journeyperson (no oil burner servicing) and the B-2 Limited Gas and Oil Burner Journeyperson, plus D-4 cooling-only, G-2 gas piping and S-10 light heating-cooling classes. A new S-2 applicant qualifies through a Connecticut apprenticeship, through equivalent experience and training (8,000 on-the-job hours and 576 classroom hours), or by holding an equivalent out-of-state license, and in every path must pass the PSI-administered S-2 exam (70 questions, 3 hours, 70%, open book). DCP states that Connecticut does not have reciprocal agreements with any other jurisdiction, even though CGS 20-333a would allow the Commissioner to waive the exam for licensees of states that reciprocate. The application fee is $90, the exam is $59 per portion and the initial license fee is $120; licenses expire every August 31 and renew for $120. EPA Section 608 refrigerant certification is a separate federal requirement for anyone handling refrigerants.

Why Tennessee has nothing to transfer

Tennessee journeyman HVAC technician

Licensed by cities and counties

Verified September 15, 2026· 12 sources

Issued by Local code enforcement offices (Chattanooga, Memphis/Shelby County, Nashville, Knoxville and other exempt jurisdictions); no state journeyman HVAC license

Tennessee has no statewide journeyman or technician HVAC license. The Board for Licensing Contractors licenses HVAC work only at the business level, through the contractor license with the CMC (full mechanical) or CMC-C (HVAC/refrigeration) classification required for projects of $25,000 or more, and it has no limited HVAC license comparable to its Limited Licensed Electrician or Plumber programs. The Department of Commerce and Insurance says that most HVAC projects under $25,000 are regulated locally and that local governments listed as exempt jurisdictions with the State Fire Marshal issue their own mechanical HVAC licenses or journeyman licenses; where the Fire Marshal's inspectors handle permits, an LLE license or a CMC-C contractor license is required for HVAC permits. Journeyman-level cards therefore exist only in cities that run their own mechanical boards: Chattanooga licenses Journeyman Mechanics ($75 per two years, three years or 6,000 hours of experience, exam through its Board of Mechanical Examiners), while Nashville and Memphis/Shelby County license mechanical contractors and let employees work under them without a personal card. An out-of-state journeyman HVAC license has no state-level recognition in Tennessee; the state's trade-exam-waiver agreements cover only contractor licenses. EPA Section 608 certification is required federally to handle refrigerants wherever the technician works.

How local licensing works in Tennessee

How local licensing works. The Board for Licensing Contractors regulates HVAC only through the CMC/CMC-C contractor license (projects of $25,000 and up). Anything below that threshold is regulated by the city or county, and roughly two dozen 'exempt jurisdictions' run their own mechanical inspection programs and licenses. Each jurisdiction's card is valid only there, and none of the pages below publishes a reciprocity or exam-waiver rule for out-of-state journeyman licenses.

Nashville (Davidson County). The Board of Mechanical, Plumbing and Electrical Examiners and Appeals issues Master Mechanical, HVAC&R, and Gas and Appliance certificates to individuals; there is no Nashville journeyman mechanical card. Technicians work as employees of a firm registered with a Metro certificate holder or a state CMC/CMC-C licensee ($40,000 permit bond, $300,000 liability insurance, Davidson County business license).

Memphis and Shelby County. The joint Office of Construction Code Enforcement licenses First-Class (4 years' experience, unlimited) and Third-Class (2 years, equipment up to 15 tons or 15 hp) Mechanical Contractors after a written exam, with a $150 registration, $110 annual renewal and a $25,000 permit bond, and registers state CMC licensees for $150. The mechanical code creates no journeyman mechanic license; employees work under a licensed mechanical contractor who must supervise them and furnish their names on request.

Knoxville. Permits are pulled under a State Contractor Registration (CMC/CMC-C), a Homeowner Registration, or an Unlicensed / State Limited License registration; the city's page does not describe a journeyman HVAC card, and its own mechanical license application could not be found online, so anyone planning to work in Knoxville should call Plans Review & Inspections at 865-215-4311.

Chattanooga. The Board of Mechanical Examiners licenses Journeyman Mechanics: three or more years (2,000 hours per year) as a registered journeyman or HVAC/sheet-metal helper, or a previously held unrevoked journeyman or HVAC mechanic license from Chattanooga or any other governmental agency, or other experience acceptable to the Board; $75 per two-year cycle; application through the OpenGov portal, after which the clerks send testing information. Holding a card from another jurisdiction makes an applicant eligible to sit the Chattanooga exam but does not waive it.

Out-of-state holders. No Tennessee jurisdiction found publishes reciprocity for journeyman HVAC licenses. In Nashville, Memphis and Knoxville a journeyman simply works as an employee of a licensed or registered mechanical contractor; in Chattanooga the out-of-state card supports eligibility for the local exam.
