Regulatory Body

Under KRS 198B.650–198B.689; 815 KAR 8:010, Kentucky Department of Housing, Buildings and Construction — Division of Heating, Ventilation and Air Conditioning (KY HVAC) is the body that issues this license and enforces compliance with it. Licenses Master HVAC Contractors and Journeyman HVAC Mechanics and administers Kentucky’s HVAC permitting and inspection program.

Eligibility Requirements

Applicants must be at least 18 years old. Check the current application for identification and tax-number requirements. Kentucky residence is not a statutory qualification. Applicants must be U.S. citizens or resident aliens authorized to work in the United States.

Good moral character

The current qualification statute focuses on age, authorized work status, experience, examination, and payment of the regulatory fee.

Background investigation

The statute and current licensing regulation reviewed do not prescribe a separate criminal-background-check requirement.

Experience and Education

Eligibility requires 2 years of A Journeyman applicant needs two years of regular and principal HVAC employment under a master contractor, or two years of documented HVAC work in Kentucky or another jurisdiction. A Master applicant may qualify through two years as a journeyman under a master contractor, two years of documented master/equivalent contracting, or two years as a licensed mechanical engineer. One year of experience means at least 1,500 HVAC-work hours in a continuous 12-month period., documented and independently verifiable. Payroll, tax, project, and supervisor records are the usual proof the board will accept.

Accepted proof of experience or eligibility

  • W-2 form
  • Affidavit from the supervising Master HVAC Contractor
  • Current out-of-state HVAC license or equivalent, where applicable
  • Other verifiable documentation of out-of-state work, or DD Form 214

Education substitution

The statute and current regulation do not provide a general schooling substitution for the two-year experience requirement.

Exam Requirements

Testing provider or authority: Kentucky Department of Housing, Buildings and Construction or its designee. The following examination requirements cover the pathways described in this guide; follow each part's classification, waiver, and local-scope conditions.

Workers' compensation

Additional financial requirements

No state financial-statement or surety-bond amount is specified in the HVAC licensing provisions reviewed.

Reciprocity

The NASCLA Accredited Examination is not accepted by Kentucky for this classification.

Reciprocal StateAccepted ExamConditions
No formal bilateral reciprocity agreements identified.

Reciprocity is available only under the agreement between Kentucky and the applicant’s licensing state. The regulation requires the applicable Kentucky application, fee, and—at the Master level—insurance documentation; it does not identify current partner states.

HVAC Licensing in Neighboring States

Contractors working near a state line, or weighing where to qualify first, should compare Kentucky's requirements against the bordering jurisdictions before committing to an application:

Step-by-Step Application Roadmap

  1. Choose the license level. Journeyman HVAC Mechanic is the work credential; the Master HVAC Contractor supervises and is primarily responsible for company HVAC work.
  2. Document two qualifying years of experience. Use W-2s, a supervising-master affidavit, a qualifying out-of-state credential/documentation, or DD Form 214 as applicable.
  3. Register for the examination. Submit the HVAC examination registration form, the applicable nonrefundable fee, and the required recent color photo.
  4. Pass the examination. The Master examination covers HVAC codes, standards, recommended practices, and HVAC business law/regulation. The Journeyman examination covers technical HVAC knowledge.
  5. Submit the initial license application. Master applicants submit Form HVAC 1 with the $250 initial fee, experience proof, examination result, and insurance proof. Journeyman applicants submit Form HVAC 2 with the $50 initial fee, experience proof, and examination result.
  6. Maintain master-level insurance. The represented company may provide the insurance certificate for a Master applicant, but the coverage must meet KRS 198B.668.
  7. Renew each year. Renew by the last day of the licensee’s birth month with the annual fee, required continuing education, and Master insurance proof.

Application Checklist

The items below are the ones worth confirming before the application is filed with KY HVAC:

Common Filing Mistakes

Based on the board's own instructions and the sources cited here, the problems below are what most often stall a Kentucky HVAC application.

Using the old four-year experience claim

The current statute requires two years of qualifying experience for the Journeyman and Master paths, subject to the Master-specific qualifying alternatives.

Treating a Master license as only an individual credential

A Master Contractor supervises and is primarily responsible for the work of the employees and subcontractors of the represented company.

Assuming any out-of-state credential is reciprocal

Kentucky requires compliance with the particular reciprocity agreement. Confirm it is active and review the Kentucky application and insurance requirements first.

Letting Master insurance lapse

The required $500,000 general liability and $300,000 property-damage coverage is a condition of a valid HVAC contracting license.
