Illinois to South Carolina: master HVAC technician license reciprocity
Illinois does not issue a statewide master HVAC technician license, so there is nothing to transfer. Here is South Carolina'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.
Licensure by examination with credit for out-of-state experience (states without a waiver agreement)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
A contractor from a state (or classification) not on the Board's waiver list is told plainly: 'you are not eligible for waiver/reciprocity. You will be required to take the SC exams.' The applicant passes the South Carolina technical exam for each classification wanted (Air Conditioning, Heating, Refrigeration or Packaged Equipment) through PSI and the South Carolina Business Management & Law for Commercial Contractors exam, then files the Qualifying Party application (Doc. 168) with proof of at least 2 years of full-time work experience performed within the past 5 years in each classification, which may have been earned in any state and should primarily reflect commercial work (a PHCC Academy of North Carolina heating and air-conditioning apprenticeship certificate is an alternative). The business files the Mechanical Contractor license application with the $350 licensure fee and a financial statement (or surety bond) meeting the group limit it wants. Section 40-11-290 separately allows the Board to exempt the technical exam for an applicant who verifies passing an essentially identical exam in another state even without a reciprocal agreement, but the Board's published waiver list and instructions do not describe a process for invoking it outside the listed states. A licensee who only wants residential work can instead apply to the Residential Builders Commission for the Residential HVAC Installer and Repairer license (one year of residential HVAC experience within the past five, residential technical exam at 65% and Business Management and Law exam, $135 application and $220 license fees, $10,000 bond for work over $5,000).
PSI exam fees are paid directly to PSI and are not published on LLR's pages. The Board's licensure page shows a $350 licensure fee but no separate qualifying-party application fee. Whether the NASCLA accredited examinations are accepted for the HVAC classifications is not stated on the pages opened (Doc. 168 mentions NASCLA transcripts generally). The current Mechanical Group financial thresholds on the licensure page (Group 2: $100,000 per job, $10,000 working capital or $15,000 net worth, $15,000 bond) differ from the 2019 waiver document's table; the web page is treated as current. EPA Section 608 certification is not mentioned on the Board's pages but is required by federal law.

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 Illinois has nothing to transfer
Illinois master HVAC technician
Licensed by cities and counties
Illinois does not issue a statewide master HVAC or mechanical contractor license and has no state mechanical board; the master-level credential exists only at the municipal level under names that vary by city. Springfield issues a Mechanical License to individuals who document 5 years (residential) or 7 years (commercial) of practical mechanical experience and pass the ICC National Standard Master Mechanical exam (G29); Peoria licenses HVAC contractors on an ICC contractor certificate from the 2018 code cycle or newer ($150 a year); Aurora and Elgin accept the ICC Master Mechanical certification or, in Elgin, a license from any Illinois city that gives a written exam; unincorporated Cook County registers HVAC contractors for a fee with $1,000,000 in liability insurance; and Chicago has no mechanical license at all, requiring a general contractor license to pull permits. None of these jurisdictions publishes a reciprocity or endorsement path for another state's master HVAC license; Springfield's only grandfather clause is limited to licenses issued before October 2007. A master HVAC contractor arriving from another state should expect to pass the ICC Master Mechanical exam once and then license or register separately in each municipality where they will work. EPA Section 608 certification applies to anyone handling refrigerants.
How local licensing works in Illinois
How local licensing works. Illinois has no state HVAC license. Each municipality licenses or registers mechanical contractors under its own ordinance; the ICC National Standard Master Mechanical exam (G29, formerly W29; residential W32) is the common denominator among testing cities.
Chicago. No HVAC or mechanical contractor license. Contractors obtain a General Contractor license from the Department of Buildings in Class A (unlimited project value, $3,500), B ($1,800), C ($1,300), D ($900) or E (projects up to $500,000, $300), each valid one year, with commercial general liability insurance from $1 million per occurrence (Class E) to $5 million (Class A) and a financial solvency statement, administered through Continental Testing Services; no trade exam.
Springfield. The Building and Zoning Department issues a person-held Mechanical License: Residential requires 5 years of practical experience in all types of mechanical work approved by the Mechanical Commission and proof of passing the ICC Master Mechanical Exam G29; Commercial requires 7 years and the same exam. Mechanical contractors also register with the city. A contractor licensed in another Illinois or out-of-state municipality with reciprocal testing may substitute that test only if the license was issued before 10/7/2007 (10/10/2007 in the earlier memo) and never lapsed; all others pass the ICC exam. Passing the exam does not itself guarantee a license.
Peoria. HVAC contractors must be licensed or registered ($150 non-refundable, calendar year) with an ICC contractor test certificate from the 2018 or newer code cycle; holders of current Normal or Pekin licenses register without retesting. Only the licensed contractor may pull permits and must attend inspections.
Aurora. Accepts a current ICC Master Mechanical certification (N29) in lieu of municipal testing; requires a certificate of insurance naming the City of Aurora as primary and non-contributory additional insured; registration through Development Services.
Elgin. Requires a mechanical contractor's license from any Illinois city that gives a written examination, or proof of passing the ICC Master Mechanical G29 exam, plus a $20,000 license and permit bond; the license is not required when an Illinois-licensed architect or engineer seals the plans and accepts responsibility.
Unincorporated Cook County. HVAC contractors register as 'all other trades' with the Department of Building and Zoning: $150 initial and $75 annual per trade, $1,000,000 general liability insurance naming the department; no exam.
Not verified. Naperville's contractor registration page was blocked when opened for this entry; Rockford publishes only electrical registration rules.
Out-of-state holders. None of these jurisdictions publishes reciprocity or endorsement for another state's master HVAC or mechanical license. The practical route is to pass the ICC National Standard Master Mechanical exam (accepted by Springfield, Peoria, Aurora and Elgin), then license or register in each municipality where work will be performed, and obtain a Chicago general contractor license for work in Chicago.
