Before an individual can take an examination for licensure as master, master restricted, limited contractor or a journeyman, an application must be filed the Board. The Board will review the application to determine which examination the applicant qualifies. Once an individual is approved, the individual's name is forwarded to the Board examination vendor, PSI, Inc. PSI will then send the applicant information to register to take the examination.
Examinations for individuals applying for licenses are conducted by PSI, Inc. on a daily basis in Baltimore, College Park, Hagerstown, and Salisbury. Individuals who have already been approved to take an HVACR examination should contact PSI at 1-800-733-9267 for an examination information packet containing exam dates, times and locations of PSI's testing centers.
