How to Get an HVAC Contractor License in Maryland

Meet Basic Requirements: Ensure you meet the age and education/experience criteria for the license type you are pursuing.

Gain Work Experience/Education: Complete an approved apprenticeship program, an HVACR certificate/degree, or accumulate the required supervised work experience.

Obtain Apprentice License: (If starting out) Apply for and obtain an Apprentice HVACR License.

Obtain Journeyman License: After gaining sufficient experience as an apprentice, apply for and pass the Journeyman HVACR exam (or may be waived if graduated from an approved apprenticeship program within two years).
Obtain EPA Section 608 Certification: Pass the EPA exam.

Apply for Master/Limited Contractor License: After fulfilling the experience requirements for the Master or Limited Contractor license (working as a Journeyman under a Master), submit the application form to the Maryland Board of HVACR Contractors. Include all necessary fees and supporting documentation (proof of education/experience, insurance certificates, etc.).

Schedule and Pass Examinations: Once your application is processed and approved, schedule and pass the relevant contractor-level exams through PSI Services.

Specialized Licenses: Maryland also offers "Restricted" licenses (Journeyman Restricted, Master Restricted) for working on specific types of HVACR systems (e.g., only air conditioning, only refrigeration, etc.).

Local Requirements: While the state license is comprehensive, always check with local county or municipal governments for any additional permits or registrations that may be required to operate in their specific jurisdiction.
