Moving to Kentucky as a journeyman HVAC technician: every state's rule

The Prov exam has 60 questions with a 3-hour limit, covering general knowledge, systems and sizing, equipment, piping, refrigeration, electrical, maintenance and plan reading; it is also offered in Spanish, and Prov allows retakes with no waiting period. The ICC version at Pearson VUE (exam 598) has 60 questions with a 3-hour limit and requires 10 days between attempts. 815 KAR 8:010 also provides a department-administered exam registered on Form HVAC-4 for $50. A passed Master HVAC exam also satisfies the journeyman exam, a passing score stays valid for three years, and an application stays open for one year while you complete the requirements. Experience can be proved with W-2s, an affidavit from the supervising master, a copy of an out-of-state license, or a DD 214 for military experience. Up to one year of HVAC work done while exempt from licensure (for example as a utility or manufacturer employee under KRS 198B.674) may count toward the two years if DHBC finds it equivalent. The application asks whether you have been convicted of a felony or misdemeanor in any jurisdiction, and DHBC warns that a conviction may prevent licensure, so contact the Licensing Branch (502-573-2002) first. Federal EPA Section 608 certification is needed to handle refrigerants but is not part of the DHBC application.
