Illinois to Kentucky: master HVAC technician license reciprocity
Illinois does not issue a statewide master HVAC technician license, so there is nothing to transfer. Here is Kentucky'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.

Out-of-state master HVAC or mechanical contractor without a reciprocity agreement (examination with experience credit)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
A master HVAC, mechanical or HVAC contractor licensee from a state without a Kentucky reciprocity agreement applies on Form HVAC 1 as a new applicant. KRS 198B.658(1)(c)2 accepts two years engaged as a master HVAC contractor 'or equivalent thereof' in a jurisdiction other than Kentucky when shown by verifiable documentation, so an out-of-state contractor does not need Kentucky journeyman time; 815 KAR 8:010 Section 5 lists a copy of a current out-of-state master HVAC contractor license or equivalent among the acceptable proofs (or documentation of the work where the state does not license), and one year of experience means at least 1,500 hours in a continuous twelve-month period. The applicant must pass the Master HVAC examination with at least 70%: it is a single open-book exam covering codes, standards and practices together with the law and regulation of the HVAC business, offered by Prov ($80) or by the department on Form HVAC-4 ($150); 815 KAR 8:010 Section 4(8) requires DHBC to recognize an equivalent examination on a showing that it covers the same material at the same level, and passing scores are valid for three years. The license issues only with a certificate of general liability insurance of at least $500,000 and property damage insurance of at least $300,000 from a Kentucky-licensed carrier naming DHBC as certificate holder (which a represented company may provide), the $250 twelve-month fee prorated by birth month ($145.83 to $375), and a passport photo; the application stays open one year.
Acceptance of a previously passed out-of-state or national master mechanical exam under Section 4(8) is at the department's discretion and no list of recognized exams is published. Exam fee: $80 per attempt with Prov; $150 for the department-administered exam registered on Form HVAC-4 (815 KAR 8:010).

Statewide license
Kentucky's highest person-held HVAC credential is the statewide Master HVAC Contractor license issued by the Department of Housing, Buildings and Construction (DHBC) to an individual who qualified by examination; the master supervises and is primarily responsible for all HVAC work of the company he or she represents (a company may carry the required insurance in its name), and only a master or journeyman may purchase the statewide HVAC permits required since 2011. A new applicant must be 18, a citizen or authorized resident alien, and have two years as a licensed journeyman under a master HVAC contractor, two years as a master HVAC contractor 'or equivalent' in Kentucky or any other jurisdiction, or two years as a licensed mechanical engineer; pass the open-book Master HVAC exam, which covers codes and practices plus the law and regulation of the HVAC business, with at least 70% (Prov $80, or the department's exam for $150 on Form HVAC-4); carry general liability insurance of $500,000 and property damage insurance of $300,000 (KRS 198B.668) naming DHBC as certificate holder; and file Form HVAC 1 with a $250 twelve-month fee prorated by birth month ($145.83 to $375). Licenses renew annually at $250 with continuing education and current insurance. KRS 198B.666 authorizes licensure by reciprocity for states with substantially equal requirements that reciprocate, and Form HVAC 1 has a reciprocity checkbox requiring a letter of good standing; DHBC publishes no HVAC partner list, but Ohio's OCILB documents an active Kentucky-Ohio HVAC and refrigeration agreement. Federal EPA Section 608 certification is required for refrigerant work but is not verified by DHBC.

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.
