1.3 Contractor Responsibilities, Supervision & Professional Ethics

Contractor Responsibilities, Supervision & Professional Ethics

Holding a Master HVAC Contractor license in Kentucky is both a professional credential and a legal public trust. Under KRS Chapter 198B and Title 815 of the Kentucky Administrative Regulations, the licensed Master HVAC Contractor assumes primary responsibility for every technical, financial, and safety aspect of mechanical contracting operations.

From maintaining mandatory insurance and compliant vehicle identification to providing bona fide field supervision and adhering to advertising standards, Kentucky law establishes strict professional benchmarks designed to eliminate dishonest practices and ensure contractor accountability.

1. Master Supervision Mandates: 815 KAR 8:010 & KRS 198B.658

The Master HVAC Contractor is the designated legal authority of the contracting business. Under 815 KAR 8:010 Section 1(1)(a), the Master shall supervise and be primarily responsible for all HVAC work performed by the employees and subcontractors of the licensee or of the company the licensee represents.

|     the Master's general direction.   (815 KAR 8:030).                      |
+-----------------------------------------------------------------------------+

Key Principles of Supervision

1. Technical and Code Compliance: The Master must ensure all installations conform to the Kentucky Building Code, Kentucky Residential Code, International Mechanical Code, NFPA standards, and local ordinances.
2. Journeyman Duties (815 KAR 8:010 Section 1(2)): A Journeyman must be physically on site, must personally observe and be responsible for each apprentice assigned to them, and must otherwise operate under the general direction and supervision of the Master.
3. Apprentice Oversight (815 KAR 8:030): Apprentices may work only under the direct supervision of at least one licensed Journeyman plus the general supervision of a licensed Master.

Company Representation & Death of a Master (815 KAR 8:010 Section 1)

• If a licensee whose license represents a company ceases to represent the company or the company name changes, the licensee must notify the department in writing and request a change of information.
• If the Master representing a company dies, the company must notify the department within ten (10) days. Under KRS 198B.667, the company may continue operating under the deceased's license for a 180-day interim period while it secures a replacement Master; it must notify the department when a replacement Master is in place before the interim period expires.

Prohibition of License "Lending" (KRS 198B.672)

One of the most heavily sanctioned violations in Kentucky construction law is license lending (allowing an unlicensed person to operate under your license):

• The Violation: A licensed Master allows an unlicensed contractor, builder, or handyman to use their Master license number to pull permits, submit bids, or advertise services without the Master actually supervising and employing the workers.
• Statutory Grounds: KRS 198B.672(2) sanctions any transfer of the authority granted by a license to another person; KRS 198B.672(6) sanctions conspiring to allow a license to be used by an unlicensed person — and allowing a license to be used by more than one person is prima facie evidence of intent to evade the law.
• Consequences: Revocation, suspension, probation, restriction, refusal to renew, reprimand, censure, or fines after a KRS Chapter 13B hearing. The unlicensed operator faces a Class A misdemeanor charge under KRS 198B.686.

2. Vehicle Identification: KRS 198B.670 & 815 KAR 2:030

To ensure consumer transparency and facilitate jobsite enforcement, Kentucky requires HVAC company vehicles to display the Master license number.

|   +---------------------------------------------------------------------+   |
+-----------------------------------------------------------------------------+

Mandatory Identification Rules (815 KAR 2:030)

1. What Must Appear: Each vehicle used in operating an HVAC business must bear the Master HVAC Contractor's Kentucky license number. (The same regulation imposes parallel requirements for electrical and plumbing businesses.)
2. Size and Visibility: All identification must be in letters and numbers not smaller than three (3) inches high and must be legible and visible on the outside of the vehicle.
3. Field Best Practice: Contractors typically apply the number in a contrasting color on both sides of service vehicles so it remains readable to inspectors and consumers; the legal floor is the 3-inch, legible, exterior-visibility standard.
4. Statutory Basis: KRS 198B.670 requires a Master HVAC Contractor's license number to appear on all vehicles used by the licensee for HVAC work.

3. Mandatory Insurance & Financial Responsibility

Under KRS 198B.668, no person, firm, or corporation may practice HVAC contracting in Kentucky without maintaining the statutorily required insurance — and no license is valid without it.

|   |                   COMMERCIAL GENERAL LIABILITY                      |   |
|   |   - Minimum Coverage: $500,000                                      |   |
|   |   - Protects against bodily injury and third-party claims.          |   |

|   |                     PROPERTY DAMAGE INSURANCE                       |   |
|   |   - Minimum Coverage: $300,000                                      |   |
|   |   - Protects customer structures and property during installation.  |   |

|   |   - Underwritten by a carrier LICENSED AND APPROVED by the          |   |
|   |     Kentucky Department of Insurance.                               |   |
|   |   - Proof submitted to the department PRIOR to issuance or renewal. |   |
|   |   - EXEMPTS licensee from separate LOCAL insurance requirements.    |   |
|   |   - NO license is valid without the required insurance.             |   |
|   |   - Carrier MUST NOTIFY the department upon cancellation.           |   |
|   +---------------------------------------------------------------------+   |
|                                     +                                       |

|   |                     WORKERS' COMPENSATION (KRS 342)                 |   |
|   |   - Mandatory for all employers with one or more employees.         |   |
|   +---------------------------------------------------------------------+   |
+-----------------------------------------------------------------------------+

Key Compliance Points

• Certificate of Insurance: Contractors submit proof of insurance (a Certificate of Insurance, customarily naming the DHBC Division of HVAC as certificate holder) with initial applications and every renewal; renewal is denied without it (815 KAR 8:010 Sections 2 and 7).
• Statewide Preemption: Proof of the state insurance satisfies — and exempts the licensee from — separate insurance requirements under local licensing laws.
• Cancellation Monitoring: Insurance carriers must notify the department upon cancellation of a licensee's policy, allowing the department to act on lapsed coverage; an inactive-status Master is exempt from maintaining insurance while inactive but may not perform HVAC work.

Workers' Compensation Insurance (KRS Chapter 342)

Under KRS Chapter 342, any contractor employing one or more individuals (including apprentices, helpers, and journeymen) must carry Kentucky-compliant Workers' Compensation insurance. Independent contractor misclassification (treating employees as 1099 independent contractors to evade workers' comp premiums) is strictly prohibited and subject to audits and penalties (see Section 2.3 of this guide).

4. Advertising Compliance & Public Representation

Kentucky law establishes strict rules regarding how mechanical contracting services are marketed to the public.

+-----------------------------------------------------------------------------+
|                     ADVERTISING COMPLIANCE CHECKLIST                        |
|                                                                             |
|   [X] Vehicles bear the Master license number (3-inch minimum, exterior,   |
|       legible) per KRS 198B.670 and 815 KAR 2:030                          |
|   [X] Only licensed Masters advertise HVAC contracting services to the     |
|       public                                                                |
|   [X] No false, deceptive, or misleading claims about efficiency, pricing, |
|       rebates, or warranties (KRS 198B.672(3))                             |
|   [X] No unlicensed person advertises or holds themselves out as a         |
|       licensed Master or Journeyman (Class A misdemeanor, KRS 198B.686(2)) |
+-----------------------------------------------------------------------------+

Advertising Rules & Prohibitions

1. Unlicensed Advertising Is Criminal: Under KRS 198B.686(2), any person who advertises or otherwise holds themselves out as a licensed Master or Journeyman without being so licensed is guilty of a Class A misdemeanor; each violation is a separate offense.
2. Title Protection (KRS 198B.656): No person may practice as, or assume and use the title of, Master contractor, Journeyman, or Apprentice without a license.
3. Deceptive Trade Practices (KRS 198B.672(3)): False or misleading statements regarding equipment efficiency, pricing, rebate eligibility, or warranties are grounds for license sanctions.

---

5. Record Retention & Trade Ethics

Professional ethics require contractors to maintain rigorous documentation and execute projects with technical integrity.

Record Retention Standards

Contractors should maintain complete project and compliance records consistent with the following statutory and regulatory minimums:

• EPA Section 608 Records (Federal): Refrigerant recovery, evacuation, leak-repair, and service records must be retained for a minimum of three (3) years under 40 CFR Part 82.
• Payroll Records (KRS 337.320): Kentucky wage-and-hour records (hours worked, gross pay, deductions) must be kept for at least three (3) years.
• Permits, Inspections & Contracts: Keep approved permits, Certificates of Approval, Manual J/S/D sizing documentation, contracts, change orders, and lien-related notices at least through the mechanics' lien enforcement window (12 months after lien filing) and equipment warranty periods — prudent contractors retain them for the life of the installation.
