Tennessee to South Carolina: master HVAC technician license reciprocity
South Carolina has a reciprocity agreement with Tennessee: a Tennessee master HVAC technician can get a South Carolina license without retaking the trade exam.
Reference only, not legal advice. Rules change; confirm with the licensing board before you apply. Full disclaimer.
Technical-exam waiver for Tennessee CMC and CMC-C mechanical licensees (AC and RG)
A signed state-to-state agreement. The trade exam is waived; you apply, prove your history, and pay the fee.
The Board's Reciprocity/Waiver Agreements list accepts the Tennessee 'CMC' (full mechanical) exam for the South Carolina Air Conditioning (AC), Refrigeration (RG) and Plumbing classifications and the 'CMC-C' (HVAC/refrigeration) exam for AC and RG; the Heating (HT) classification is not listed for Tennessee. A Tennessee licensee who passed one of those exams and holds a current license in good standing (not grandfathered or waived in) has the AC and RG technical exams waived but must still pass the South Carolina Business Management & Law for Commercial Contractors exam through PSI, have the Tennessee Board for Licensing Contractors complete the SC Examination Waiver form, document 2 years of experience within the past 5, and file the Qualifying Party application; the business then pays the $350 licensure fee and files its financial statement or bond.

How South Carolina licenses master HVAC technicians
South Carolina master HVAC technician · “Mechanical Contractor, Air Conditioning (AC) / Heating (HT) / Refrigeration (RG) classification - Qualifying Party certification”
Statewide license
South Carolina has no 'master HVAC' license. The highest person-held HVAC credential is the Contractor's Licensing Board's Qualifying Party certification in the Air Conditioning (AC), Heating (HT), Refrigeration (RG) or Packaged Equipment (PK, up to 25 tons and 500,000 BTU per unit) classification of the Mechanical Contractor license: the individual passes the South Carolina technical exam for each classification through PSI and the South Carolina Business Management & Law for Commercial Contractors exam, documents two years of experience within the past five (or a PHCC Academy of North Carolina heating and air-conditioning apprenticeship), and is certified as the qualifying party for a licensed entity (which may be a sole proprietorship); the certification stays with the person, who 'is not a licensed contractor' alone. The license itself is issued to the business, with a $350 licensure fee and a financial statement or surety bond sized by license group (Mechanical Group 2, jobs to $100,000: working capital $10,000 or net worth $15,000, or a $15,000 bond). A residential-only alternative is the Residential Builders Commission's Residential HVAC Installer and Repairer license ($135 application, $220 license), issued to the individual after one year of residential HVAC experience and the residential technical plus Business Management and Law exams. South Carolina has technical-exam waiver agreements, listed in the Board's Reciprocity/Waiver Agreements document, covering HVAC classifications for Georgia (Un-Restricted Conditioned Air), Louisiana (Statewide Mechanical), Ohio (HVAC, packaged equipment only), Tennessee (CMC and CMC-C), Texas (Class A and Class B ACR) and Utah (S350, S353, S351, S360), plus the MASC/CAGC HARV Master Mechanical card; Alabama, Mississippi and North Carolina licenses waive only the residential license's technical exam. Every waiver applicant must still pass the South Carolina Business Management & Law exam. Licensees from other states take the South Carolina technical exam. EPA Section 608 certification is a separate federal requirement.
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.
