HVAC Contractor License in Kentucky: Requirements, Qualifier, Bond and Exams

Yes.

Kentucky licenses HVAC contracting at the state level, and the Department of Housing, Buildings and Construction (DHBC) is the agency behind all of it: DHBC issues the master HVAC contractor license, the journeyman HVAC mechanic license and the apprentice HVAC mechanic certificate.

For a business, the load-bearing rule is responsible charge: a company must have a master HVAC contractor — an employee or a subcontractor — in responsible charge of its heating, ventilation and air conditioning work.

Kentucky does not require a license for every worker on the crew: employees of a master HVAC contractor who are subordinates of the licensee, who are not journeymen or apprentices and do not contract on their own, are exempt from the HVAC licensing law.

Our Kentucky HVAC license guide for individuals covers the worker side.

The agency is the Kentucky Department of Housing, Buildings and Construction (DHBC).

Its HVAC credential list is short: the master HVAC contractor license for contracting businesses, the journeyman HVAC mechanic license for workers, and the apprentice HVAC mechanic certificate, which apprentices and pre-apprentices can register for free of charge.

In what we read, the master HVAC contractor license is the single credential on the contractor side: the person in responsible charge of a contracting business's HVAC work must hold it, as an employee or a subcontractor.

Kentucky's qualifier is the master HVAC contractor.

A company must keep one — an employee or a subcontractor — in responsible charge of its HVAC work, and the master must notify DHBC when the employment starts and when it ends.

To become a master HVAC contractor, the statute requires 2 years as a journeyman HVAC mechanic under the direction and supervision of a master, or 2 years as a master-equivalent contractor elsewhere, or 2 years as a licensed mechanical engineer; the applicant must be at least 18 and pass the exam.

The journeyman step beneath has its own requirements: 2 years of HVAC work under a master HVAC contractor (or 2 years of verifiable HVAC work in Kentucky or elsewhere) and the department exam, and one academic year of a department-approved HVAC curriculum can count as one year of that journeyman experience, to a maximum of one year.

One representation rule caps a qualifier's reach: a master may represent only one company unless they are domiciled in Kentucky and own at least 25% of each company represented.

The exams run up the ladder.

The master HVAC contractor applicant must pass the exam, and the journeyman HVAC mechanic beneath the qualifier passes the department exam too; the fee schedule sets the non-refundable exam fees at $150 for a master HVAC contractor and $50 for a journeyman HVAC mechanic.

What the statutes and regulations we read do not name is a separate business-and-law exam for the master license — the exam requirement our research confirms is the department exam — and they do not name the exam vendor either.

Ask DHBC which testing company administers the current exams and how to schedule before you book anything.

Kentucky writes its insurance minimums into the statute: an HVAC contractor must maintain general liability insurance of at least $500,000 and property damage insurance of at least $300,000; the license application needs proof of insurance.

The state proof does double duty — an HVAC contractor who proves the state insurance is exempt from separate local insurance requirements.

A bond is the open part: what we read sets no bond amount for HVAC contractors, but the statute that keeps a company running after its master dies refers to keeping bonding and insurance in force during the interim period, so ask DHBC what bonding, if any, your situation requires.

The master HVAC contractor license costs $250 to start: the initial license application fee is $250 for a 12-month license, and the application needs proof of insurance.

After that it renews every year — the renewal application is due no later than the last day of the licensee's birth month, at $250 for a master HVAC contractor.

Continuing education rides along: at least 6 hours of approved continuing education in the 12 months before each annual renewal, on topics that include business, job safety, codes and trade subjects, and up to 12 excess hours may be carried forward.

The exam fee, $150 for a master HVAC contractor, is a separate, non-refundable line.

Kentucky's statute offers a conditional door rather than a list of named agreements: the department may issue an equivalent HVAC license to someone licensed in a state with substantially equal or greater requirements, where that state grants Kentucky licensees the same privilege, and the terms and conditions are determined by the department.

No partner states are named in what we read, so do not assume your state qualifies on reputation.

Ask DHBC whether your state's license meets the equal-or-greater test and what documentation it wants before you assume what Kentucky will require of you.

The rule on the books covers death.

If a Kentucky HVAC company's master dies, the department grants an interim period of up to 180 continuous calendar days during which the company may operate on the deceased master's license while keeping bonding and insurance in force; after that, the company must have a new licensed master to pull permits.

What our research did not find is a replacement deadline for a master who leaves for any other reason — resignation, retirement, a move to another company.

The master's duty to notify DHBC when employment ends still applies.

Treat the 180-day window as the death-only rule it is, and ask DHBC promptly what applies when your qualifier departs another way.
