How Do You Get an HVAC License in Kentucky?
Yes.
Kentucky licenses HVAC work statewide through the Department of Housing, Buildings and Construction (DHBC): an apprentice HVAC mechanic certificate, a journeyman HVAC mechanic license and a master HVAC contractor license.
The journeyman step takes 2 years of HVAC experience — under a master HVAC contractor, or verifiable HVAC work in Kentucky or elsewhere — plus the department exam.
Not everyone needs a license: unlicensed employees of a master HVAC contractor who are not journeymen or apprentices, and do not contract on their own, are exempt.
Licenses renew yearly, with 6 hours of continuing education.

The Kentucky HVAC license ladder
- Apprentice HVAC Mechanic CertificateEntry level
A free certificate of registration with DHBC for HVAC apprentices and pre-apprentices; experience earned while registered as a state apprentice under a licensed master HVAC contractor counts toward the journeyman requirement.
- Journeyman HVAC MechanicJourneyman
The license that lets you claim or advertise the journeyman HVAC mechanic title, after 2 years of experience and the department exam.
- Master HVAC ContractorContractor
The top rung: a company must have a master HVAC contractor in responsible charge of its HVAC work, qualified by 2 years as a journeyman under a master (or equivalents) plus the exam.
Does Kentucky require a state HVAC license?
Yes.
Kentucky licenses HVAC work statewide through the Department of Housing, Buildings and Construction (DHBC), which issues three HVAC credentials: the master HVAC contractor license, the journeyman HVAC mechanic license and the apprentice HVAC mechanic certificate.
The licenses do not reach every worker: unlicensed employees who work under a master HVAC contractor, and who are not journeymen or apprentices and do not contract on their own, are exempt from Kentucky's HVAC licensing law.
Confirm the current rules with DHBC before you rely on any title or exemption.
“A person shall not claim to be or advertise as being a journeyman heating, ventilation, and air conditioning mechanic”
What are the Kentucky HVAC license levels, and what can each legally do?
DHBC's three levels are the apprentice certificate, the journeyman HVAC mechanic license and the master HVAC contractor license.
Unlicensed employees of a master HVAC contractor who are not journeymen or apprentices, and who do not contract on their own, are exempt from the licensing law.
The journeyman license is what lets you claim or advertise the journeyman title.
The master HVAC contractor license is the top rung: a company must have a master HVAC contractor, either an employee or a subcontractor, in responsible charge of its HVAC work, and that master must notify DHBC when the employment starts and ends.
Our HVAC contractor license by state guide covers the employer side of that license.
What are the requirements for each level: hours, training, exam and fees?
Journeyman HVAC mechanic applicants must be at least 18 and have 2 years of HVAC work under the direction and supervision of a master HVAC contractor, or 2 years of verifiable HVAC work in Kentucky or elsewhere, then pass the department exam.
One academic year of a department-approved HVAC curriculum, or one year of professional training, can count as one of those two years — maximum one year.
Experience earned while registered as a state apprentice under a Kentucky licensed master HVAC contractor also counts toward the 2 years.
The journeyman exam fee is $50, non-refundable.
Master HVAC contractor applicants need 2 years as a journeyman HVAC mechanic under a master, or 2 years as a master-equivalent contractor elsewhere, or 2 years as a licensed mechanical engineer, must be 18 or older, and pass the exam; the master exam fee is $150 and the initial license is $250 for 12 months, with proof of insurance required with the application.
Apprentices and pre-apprentices register with DHBC free of charge.
“Have been regularly and principally employed or engaged in heating, ventilation, and air conditioning trades for not less than two (2) years under the direction and supervision of a master heating, ventilation, and air conditioning contractor”
Who gives the Kentucky HVAC exam, and what is on it?
The journeyman requirement is to pass the department exam, and the master HVAC contractor requirement is to pass the exam as well.
The fees are set in administrative regulation: $50 for the journeyman HVAC mechanic exam and $150 for the master HVAC contractor exam, both non-refundable.
What we cannot tell you is who administers the tests or what is on them — our research read Kentucky's HVAC statutes and regulations and did not identify the testing vendor or a content outline for the state's HVAC exams.
Ask DHBC for the current candidate information before you schedule.
How do you renew, and how many CE hours does Kentucky require?
Kentucky HVAC licenses renew every year.
The renewal application is due no later than the last day of the licensee's birth month, and the renewal fee is $50 for a journeyman HVAC mechanic and $250 for a master HVAC contractor.
Every licensee also completes at least 6 hours of approved continuing education in the 12 months before each annual renewal, in subjects that include business, job safety, codes and trade topics, and up to 12 excess hours may be carried forward.
Confirm the current renewal details with DHBC before you file.
“application for license renewal shall be filed no later than the last day of the licensee's birth month”
Does Kentucky accept HVAC licenses from other states?
Kentucky can.
The statute says an equivalent HVAC license may be issued to someone licensed in another state whose requirements are substantially equal to or greater than Kentucky's, where that state grants Kentucky licensees the same privilege, on terms and conditions determined by the department.
That is a conditional, department-decided path rather than an automatic transfer, and our research did not name any specific states that Kentucky has HVAC reciprocity agreements with.
If you hold an out-of-state HVAC license, ask DHBC how it will be treated before you count on it.
“may be issued an equivalent license in this state upon terms and conditions determined by the department”
How do you look up a Kentucky HVAC license?
The lookup is DHBC's License Search and Verification page on dhbc.ky.gov — a link our research recorded from the department's site navigation rather than by opening the search page itself, so start from dhbc.ky.gov and follow the License Search and Verification link rather than trusting a third-party copy of the address.
Search it before you hire a contractor, and before you accept a job with a company that claims licensed status.

Frequently Asked Questions
Do you need a license to do HVAC work in Kentucky?
It depends on the work.
Kentucky requires a license to claim or advertise the journeyman HVAC mechanic title, to work as a master HVAC contractor, and to be the master in responsible charge of an HVAC company's work.
But not every worker needs one: unlicensed employees of a master HVAC contractor who are not journeymen or apprentices and do not contract on their own are exempt from the licensing law.
If you want the title and the contracting path, the journeyman license is the step to plan for.
How much does an HVAC license cost in Kentucky?
The exam fees are $50 for the journeyman HVAC mechanic exam and $150 for the master HVAC contractor exam, both non-refundable.
The initial master HVAC contractor license is $250 for 12 months, and the application needs proof of insurance.
Renewals are annual: $50 for a journeyman and $250 for a master HVAC contractor.
The apprentice certificate is free.
Fees are set in administrative regulation and can change, so confirm the current fees with DHBC before you apply.
How long does it take to become a journeyman HVAC mechanic in Kentucky?
Plan on 2 years of experience: the requirement is 2 years of HVAC work under the direction and supervision of a master HVAC contractor, or 2 years of verifiable HVAC work in Kentucky or elsewhere.
One academic year of a department-approved HVAC curriculum — or one year of professional training — can count as one of those years, and no more.
Experience from a registered state apprenticeship under a Kentucky licensed master HVAC contractor counts too.
You then pass the department exam.
What is the difference between a journeyman HVAC mechanic and a master HVAC contractor in Kentucky?
The journeyman HVAC mechanic license is the worker license: 2 years of HVAC experience and the department exam qualify you to claim or advertise the journeyman title.
The master HVAC contractor license is the supervising license: a company must have a master in responsible charge of its HVAC work, and qualifying takes 2 years as a journeyman under a master — or 2 years as a master-equivalent contractor elsewhere, or 2 years as a licensed mechanical engineer — plus the exam.
Do Kentucky HVAC techs need EPA 608 certification?
If you work on refrigerant, yes — that is federal law, not a Kentucky rule.
Under 40 CFR 82.161, any person who could reasonably be expected to violate the integrity of the refrigerant circuit while maintaining, servicing, repairing or disposing of appliances containing CFC/HCFC or non-exempt substitute refrigerants (such as HFCs) must pass an exam from an EPA-approved technician certification program.
EPA 608 is a federal certification, separate from any state HVAC license.
