1.1 Kentucky HVAC Licensing & DHBC Regulatory Framework
Key Takeaways
- The Kentucky Department of Housing, Buildings and Construction (DHBC) Division of HVAC administers and enforces KRS 198B.650–198B.689 and 815 KAR Chapter 8 statewide; the 2017 reorganization placed all licensing, examination, inspection, and disciplinary authority directly in the department.
- Under KRS 198B.658, Master HVAC Contractor candidates qualify through one of three 2-year pathways: 2 years as a licensed KY Journeyman under a Master, 2 years of Master (or equivalent) HVAC contracting experience in Kentucky or any other jurisdiction, or 2 years as a licensed mechanical engineer.
- Initial license application fees are $250 (Master) and $50 (Journeyman) payable to the DHBC and prorated to the applicant's birth month; the Prov examination costs $80; annual renewal is $250 (Master) or $50 (Journeyman).
- All licenses expire annually on the last day of the licensee's birth month; a 60-day grace period allows restoration with a fee, licenses then terminate, and reinstatement without re-examination is available for three (3) years; 6 hours of approved continuing education is required annually under 815 KAR 2:010.
- Registered Apprentices pay no registration fee, work under the direct supervision of at least one licensed Journeyman and the general supervision of a Master HVAC Contractor, and must keep personal records of their employment hours.
Kentucky HVAC Licensing & DHBC Regulatory Framework
For mechanical contractors preparing for the Kentucky Master HVAC Contractor Examination (Prov Exam 595), mastering the legal and regulatory framework governing the trade is essential. In the Commonwealth of Kentucky, the heating, ventilation, and air conditioning industry is strictly regulated to protect public health, safety, and property. The statutory foundation is established by the Kentucky General Assembly under Kentucky Revised Statutes (KRS) Chapter 198B, Sections 198B.650 through 198B.689, and the detailed operational mandates are promulgated under Title 815 of the Kentucky Administrative Regulations (KAR), Chapter 8.
Understanding the jurisdiction of the Department of Housing, Buildings and Construction (DHBC), the tiered hierarchy of licensure, financial requirements, and annual compliance milestones is vital both for passing the licensing examination and for legally operating a mechanical contracting enterprise.
1. Statutory Authority: KRS Chapter 198B & The DHBC
The regulation of HVAC contracting in Kentucky operates under the executive authority of the Public Protection Cabinet, specifically through the Department of Housing, Buildings and Construction (DHBC). Within the DHBC, all licensing, examination, inspection, and enforcement duties are administered by the Division of Heating, Ventilation, and Air Conditioning (HVAC).
Under the 2017 reorganization of KRS Chapter 198B (2017 Ky. Acts ch. 169), the powers formerly exercised by advisory boards were consolidated directly into the department itself. Per KRS 198B.654, the department promulgates administrative regulations, conducts examinations, maintains licensee and apprentice registers, conducts disciplinary proceedings and investigations, issues licenses and certificates, and may seek injunctive relief without posting bond.

4. Fee Schedules, Renewal Cycles & Continuing Education
Official Fee Schedule (815 KAR 8:010)
Kentucky administrative regulations establish the following fee schedule payable to the Kentucky State Treasurer:
- Initial Master License Application Fee: $250 for a 12-month license, prorated between 7 and 18 months so the license expires on the final day of the applicant's birth month.
- Initial Journeyman License Application Fee: $50, prorated the same way.
- Examination Fee: $80 per exam, paid to the testing vendor (Prov) per the current Candidate Information Bulletin. (The $150 / $50 examination fees in 815 KAR 8:010 Section 4(5) apply to department-provided examinations.)
- Annual Renewal Fees: $250 for Master Contractors and $50 for Journeyman Mechanics.
- Restoration Fee (late renewal within the 60-day grace period): $125 (Master) or $25 (Journeyman).
- Reinstatement Fees (terminated licenses, within 3 years): $250 per 12-month period, capped at $750 (Master); $50 per 12-month period, capped at $150 (Journeyman).
- Inactive Status Fee / Reactivation Fee: $20 each.
- Score Validity: A passing examination score is valid for three (3) years.
Birth-Month Renewal System (KRS 198B.664)
Kentucky operates an individualized birth-month renewal cycle for all HVAC licenses:
- Expiration Date: Every Master HVAC Contractor and Journeyman HVAC Mechanic license expires on the last day of the licensee's birth month each year.
- Renewal Filing: The department sends a renewal application notice to each licensee annually. The licensee must submit the renewal application (Form DHBC L-1), the appropriate fee ($250 Master / $50 Journeyman), proof of compliant insurance (for Masters), and proof of the required 6 hours of continuing education.
- 60-Day Grace Period: A license that is not timely renewed expires, but the licensee may continue to practice during a 60-day grace period and may restore the license by paying the renewal fee plus the restoration fee ($125 Master / $25 Journeyman) and providing proof of insurance.
- Termination & Reinstatement: A license not restored within the 60-day grace period is terminated. A former licensee may reinstate within three (3) years of termination by satisfying the renewal requirements and paying the reinstatement fee — without retaking the examination. After three years, the individual must satisfy all requirements for initial licensure, including re-examination.
- Inactive Status: A licensee not practicing in Kentucky may place the license on inactive status ($20 fee); inactive licensees are exempt from renewal, CE, and (for Masters) insurance, but may not perform HVAC work. Reactivation costs $20 plus proof of CE compliance.

+-----------------------------------------------------------------------------+
Continuing Education (CE) Mandates: 815 KAR 2:010
Under 815 KAR 2:010, ongoing professional development is mandatory for license renewal:
- Hours Required: All Master HVAC Contractors and Journeyman HVAC Mechanics must complete six (6) hours of approved continuing education during the twelve (12) months prior to each renewal.
- Approved Subject Matter: HVAC CE courses must relate to one or more of: (a) business; (b) job safety; (c) codes relating to HVAC; or (d) subject matter directly relating to the HVAC trade.
- Safety Cap: No more than two (2) hours of safety practices and procedures per 12-month period counts toward the annual requirement.
- Carry-Forward: Excess CE hours may be carried forward into the two (2) successive educational years, capped at a total of twelve (12) hours.
- First Renewal Exemption: The CE requirement is waived for a licensee's first renewal if the initial license was issued within twelve (12) months of that renewal.
- Proof: CE proof must be submitted to the department before renewal; providers and licensees may also request approval of relevant out-of-state courses.
5. Reciprocity & Out-of-State Licensure (KRS 198B.666)
Kentucky law provides two distinct routes for out-of-state contractors:
- Direct Qualification (KRS 198B.658(1)(c)): An applicant with at least two (2) years of verifiable Master (or equivalent) HVAC contracting experience — or two years as a licensed mechanical engineer — in Kentucky or any other jurisdiction may apply directly for the Kentucky Master examination without first holding a Kentucky Journeyman license.
- Reciprocity (KRS 198B.666): A person licensed in another state whose licensing, educational, and experience requirements are substantially equal to or greater than Kentucky's — and which grants equal licensing privileges to Kentucky licensees — may be issued an equivalent Kentucky license on terms set by the department. Per 815 KAR 8:010 Section 3, reciprocity applicants must comply with the applicable reciprocity agreement and file the standard application and fees.
[!NOTE] Exam Preparation Strategy: Questions on the Kentucky Master exam regarding licensing test specific numbers: the $250 Master application fee, the $50 Journeyman application fee, the $80 Prov examination fee, $250 / $50 annual renewals, the $125 / $25 restoration fees, birth-month expiration, the 60-day grace period, the 3-year reinstatement window, 6 hours of annual CE, the 1,500-hour experience year, and the three 2-year Master qualification pathways (KY Journeyman, out-of-state Master/equivalent, or mechanical engineer). Memorize these figures precisely.
