Tennessee to Texas: journeyman HVAC technician license reciprocity
Tennessee does not issue a statewide journeyman HVAC technician license, so there is nothing to transfer. Here is Texas'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.
Technician registration required of everyone (no exam, no reciprocity)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
An HVAC technician or journeyman licensed in any other state must register with TDLR as an Air Conditioning and Refrigeration Technician before assisting a Texas ACR contractor; the registration is a $20, no-exam filing that does not evaluate or credit the out-of-state license. TDLR publishes no reciprocity, endorsement or exam waiver at this level because there is no exam to waive. A technician who wants the optional Certified Technician designation must meet the Texas experience or training requirement and pass the PSI Certified Technician exam; TDLR's certified technician page does not describe any credit for an out-of-state license.
Applicants without a criminal conviction receive a 21-day temporary registration on filing (16 TAC §75.27). TDLR's published materials do not say whether supervised experience from another state counts toward the voluntary Certified Technician credential.

How Texas licenses journeyman HVAC technicians
Texas journeyman HVAC technician · “Registered Air Conditioning and Refrigeration Technician”
Statewide license
Issued by Texas Department of Licensing and Regulation (TDLR)
Texas has no journeyman HVAC license in the usual sense; the person-held credential for an employee who does air conditioning and refrigeration work is the Registered ACR Technician registration issued by the Texas Department of Licensing and Regulation (TDLR). Anyone who assists a licensed ACR contractor with non-exempt maintenance or repair work must register: the applicant must be at least 16, file a one-page application with a $20 fee and answer a criminal history questionnaire, and there is no exam, no experience requirement and no continuing education. The registration is valid one year and is renewed for $20. TDLR also offers a voluntary Certified ACR Technician credential for technicians with 24 months of supervised experience or a TDLR-approved 2,000-hour training program who pass a PSI exam ($50 application, $60 exam, renewed for $35); it is not required to work. Because the registration is not an examined license, an out-of-state journeyman or technician license has nothing to transfer to: every technician must register with TDLR regardless of licenses held elsewhere, and all work must be performed under a Texas-licensed ACR contractor. Technicians who handle refrigerants also need federal EPA Section 608 certification.
Why Tennessee has nothing to transfer
Tennessee journeyman HVAC technician
Licensed by cities and counties
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 is not posted 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.
