Starting as an apprentice
Kentucky has no apprentice credential — you can start with no card of your own
No apprentice license or registration exists - the unlicensed apprentice works under a journeyman who is PHYSICALLY ON SITE and personally responsible.
Bringing your license from another state
Kentucky licenses the individual — the JOURNEYMAN HVAC MECHANIC ($50 initial, $50 a year) under a MASTER HVAC CONTRACTOR ($250) — and its reciprocity is agreement-based, per partner: applicants comply with the terms of the specific agreement between Kentucky and their state, which vary per agreement. The partner list itself is the open item — Kentucky's own list was not obtainable — but one corridor is verified from the other side:
Ohio's contractor-level reciprocity fleet includes Kentucky. Ask the HVAC division for the current agreement list before planning a transfer.
Can you work while it is pending?
Not established for the journeyman license — no pending-application provision in the regulation. The immediate-placement option is structural: the unlicensed apprentice lane under an on-site journeyman (see apprentice).
The exam and the hours
Read from the regulation: an experience YEAR is defined as at least 1,500 hours of HVAC work in a continuous twelve months. The journeyman exam passes at 70% ($50, PROV); the master exam adds law-and-regulation scope ($150). Your personal floor is EPA 608.
How apprenticing works here
No apprentice license or registration exists — confirmed in the regulation. The unlicensed apprentice works under a journeyman who is PHYSICALLY ON SITE and personally responsible — which means crew apprentice headcount is bounded by on-site journeyman headcount. Plan crews accordingly.
The local picture
The state program governs statewide.
If you want to contract for yourself
The master HVAC contractor supervises and is primarily responsible for all HVAC work performed by employees and subcontractors — the journeyman works under that umbrella. A traveler needs the journeyman card; the master credential is the business anchor.
