Key Provisions:

Sales Restricted to Licensed Professionals: HVACR equipment may only be sold to an individual or a business who:

holds or employs a holder of a Master, Master Restricted, or Limited License issued by the State Board of Heating, Ventilation, Air–Conditioning, and Refrigeration Contractors, or employ an individual who holds one of these licenses;
operates a business that resells equipment to licensed HVACR professionals; or
falls under a statutory exemption set forth in Maryland Annotated Code, Business Regulation Article § 9A–103.

Penalties for Violations:

First violation: Civil penalty up to $1,000. Maryland Annotated Code, Business Regulation Article §§ 9A–501.1 and 9A-505.
Second or subsequent violations: Civil penalty up to $5,000. Id.

What This Means for Licensees:

Ensure your license is current and valid so that you can continue to purchase HVACR equipment without interruption.
