California to Kentucky: journeyman HVAC technician license reciprocity
California does not issue a statewide journeyman 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.
Reference only, not legal advice. Rules change; confirm with the licensing board before you apply. Full disclaimer.
Out-of-state journeyman HVAC mechanic without a reciprocity agreement (examination with experience credit)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
An HVAC journeyman or technician licensed in a state without a Kentucky reciprocity agreement applies on Form HVAC 2 as a new applicant. KRS 198B.658(2)(c)2 expressly accepts two years of HVAC work performed 'in a jurisdiction other than Kentucky' when shown by verifiable documentation, and 815 KAR 8:010 Section 5 lists a copy of a current out-of-state journeyman HVAC license (or, for states that do not license, documentation of the work performed) among the acceptable proofs, alongside W-2s, a supervising master's affidavit or a DD 214; one year of experience means at least 1,500 hours in a continuous twelve-month period. The applicant must pass the Journeyman HVAC examination with at least 70%, either the Prov computer-based open-book exam ($80) or the department-administered exam registered on Form HVAC-4 ($50); 815 KAR 8:010 Section 4(8) requires DHBC to recognize another examination as equivalent when the applicant or a testing agency demonstrates it covers the same material at the same level, and a passing score is valid for three years. The $50 twelve-month application fee is prorated by birth month to between seven and eighteen months ($29.17 to $75), a passport-sized color photo is required, and the application stays open for one year while requirements are completed. There is no separate law or business exam for the journeyman license.
Whether a previously passed out-of-state or national journeyman HVAC exam will be accepted under 815 KAR 8:010 Section 4(8) is decided by the department case by case; no list of recognized exams is published. Prov charges $80 per exam attempt, while the department's own journeyman exam, registered on Form HVAC-4, costs $50 under 815 KAR 8:010.

How Kentucky licenses journeyman HVAC technicians
Kentucky journeyman HVAC technician · “Journeyman HVAC Mechanic”
Statewide license
Kentucky issues a statewide Journeyman HVAC Mechanic license through the Department of Housing, Buildings and Construction (DHBC) under KRS 198B.650 to 198B.689; a journeyman performs HVAC work under the supervision, direction and responsibility of a licensed Master HVAC Contractor and supervises registered apprentices on site. A new applicant must be 18, a citizen or authorized resident alien, have two years of HVAC experience (at least 1,500 hours per year) either under a master HVAC contractor or as verifiable HVAC work in Kentucky or any other jurisdiction, pass the open-book Journeyman HVAC exam with at least 70% (offered through Prov for $80, or by the department for $50 on Form HVAC-4), and file Form HVAC 2 with a $50 twelve-month fee prorated by birth month ($29.17 to $75) and a passport photo. Licenses renew annually at $50 with continuing education. KRS 198B.666 and 815 KAR 8:010 Section 3 provide for licensure by reciprocity where an agreement exists with the licensing state, and the application form has a reciprocity checkbox, but DHBC's HVAC pages publish no list of partner states; every other out-of-state journeyman documents their hours and takes the Kentucky exam. Federal EPA Section 608 certification is required for refrigerant work but is not part of the DHBC application.
Why California has nothing to transfer

No individual license at this level
Issued by Contractors State License Board (contractor licensing only)
California does not issue a journeyman, technician or mechanic license for heating, ventilation, air-conditioning or refrigeration work. The only state HVAC credentials are contractor classifications issued by the Contractors State License Board (CSLB) to a business: C-20 Warm-Air Heating, Ventilating and Air-Conditioning Contractor and C-38 Refrigeration Contractor (systems below 50°F). Under Business and Professions Code §7053 the Contractors State License Law does not apply to a person who does the regulated work as an employee for wages, so HVAC technicians employed by a C-20 or C-38 contractor work without any personal state license; California's personal certification program for electricians (Labor Code §108) has no HVAC counterpart, and no city or county HVAC mechanic license was found in the largest jurisdictions (Los Angeles issues mechanical permits to licensed contractors and lists no HVAC technician license). An out-of-state journeyman or HVAC technician license therefore has nothing to transfer to in California and is neither required nor recognized for employment. The federal EPA Section 608 technician certification still applies to anyone who services equipment containing refrigerants. A technician who wants to contract independently must obtain a C-20 or C-38 license, described at the master level.
