Hvac Licensing in Maryland

Maryland HVAC License Verification

In Maryland, all individuals performing heating, ventilation, air conditioning, and refrigeration (HVACR) work must be licensed through the state, starting from the apprentice level. The governing body for HVACR licensing in Maryland is the Maryland Board of Heating, Ventilation, Air Conditioning and Refrigeration Contractors (HVACR), which operates under the Maryland Department of Labor’s Division of Occupational and Professional Licensing. To obtain a license, applicants must be at least 18 years old and possess a high school diploma or GED equivalent. The licensing process typically begins with an apprenticeship, followed by several years of supervised work experience, culminating in journeyman and then master-level licenses. Each license classification requires passing a specific examination administered by PSI Examination Services, with a minimum score of 70%. Licenses must be renewed every two years.

Insurance and Bonding Mandates

For Master, Master Restricted, and Limited HVACR Contractors in Maryland, specific insurance coverage is mandatory. These contractors are required to maintain general liability insurance with coverage of at least $300,000 and property damage liability insurance of at least $100,000. The combined total of general liability and property damage insurance must be a minimum of $400,000. It is critical that the contractor's name, policy number, and expiration date appear on the insurance certificate, and the Maryland Board of HVACR Contractors must be named as the certificate holder. Furthermore, businesses with employees are legally required to carry Workers' Compensation insurance. Operating without the mandated insurance can lead to significant penalties, including fines or imprisonment.

Permitting and Local Regulations

Most HVACR work undertaken in Maryland, particularly new installations and significant system alterations, necessitates obtaining a permit. These permits are crucial for ensuring that installations and upgrades adhere to established safety standards and codes, including the International Mechanical Code (IMC) and the National Electrical Code (NEC). While state licenses are issued by the Maryland Board of HVACR Contractors, local jurisdictions, such as counties and cities, often impose additional permitting requirements and may have their own specific building and mechanical codes. For example, Anne Arundel and Prince George's Counties require individuals to hold a county HVACR license in addition to the state license. Contractors should always consult with local permit agencies to understand and comply with all applicable local regulations before commencing any HVACR work.
