What license tiers does Maryland offer?
Six credentials plus an inspector license. Apprentice is the entry registration. From there the ladder splits: journeyman restricted needs three years and 1,875 hours, full journeyman needs four years and 6,000 hours. Above journeyman sit three options, limited contractor after two years and 1,000 hours in the prior year, master restricted after three years and 1,875 hours in the prior year, and master on the same three-year clock. Master is the only tier with unrestricted statewide scope as a qualifying individual. The restricted tiers are scoped by area, which is also how they are priced.
What is the Maryland HVAC exam like?
PSI administers every Maryland HVACR exam, with 70% to pass at each level. The journeyman exam runs 100 questions in four hours. Journeyman restricted, master restricted, and limited each run 50 questions in two hours. Those question counts and time limits come from exam prep vendors rather than the board's own exam page, so confirm them before scheduling. Licensed Virginia and Delaware journeymen and masters can apply by reciprocity rather than sitting the exam at all.
How much does an HVAC license cost in Maryland?
State license fees run $12 apprentice, $25 journeyman or journeyman restricted per area, $94.50 master or limited, and $31.50 per area for master restricted, all on the schedule effective July 1, 2025. Inactive status is $31.50 and a letter of good standing is $25. The whole ladder totals about $131.50 in state fees. PSI exam fees are separate at each level. Every classification except journeyman must carry general liability of at least $300,000 and property damage liability of at least $100,000, which is the largest ongoing cost. Maryland requires no surety bond.
How long does it take to become an HVAC tech in Maryland?
The clock is the 6,000 supervised hours, roughly 4 years of full-time paid work. Maryland runs the deepest credential ladder in the region, six HVACR tiers plus an inspector license, all through one state board covering residential and commercial work. The full climb is about seven years, four as an apprentice to reach journeyman and three more as a journeyman to reach master.
Is HVAC a good career in Maryland?
Maryland figure is the BLS state median for HVAC mechanics and installers (May 2024). National median from the U.S. Bureau of Labor Statistics (May 2024). Verify current figures with BLS.
What does it take to start your own HVAC business in Maryland?
An HVACR business in Maryland operates under a licensed master or limited contractor acting as its qualifying individual. Every classification except journeyman must carry general liability of at least $300,000 and property damage liability of at least $100,000. The board requires no surety bond, which sets Maryland apart from most of its neighbors. Licenses renew on a two-year cycle, and remember that the master restricted fee is charged per area licensed rather than once.
What most guides get wrong about Maryland
The board reset its entire fee schedule on July 1, 2025, and most of the internet is still quoting the old one. Master is $94.50 now, not the $75 that the large software directories still publish, and journeyman moved to $25. The detail nobody itemizes at all: master restricted is $31.50 per area licensed rather than a flat fee, so a contractor qualified in three areas pays three times. The second trap is that Maryland has two different journeyman credentials. Journeyman restricted takes three years and 1,875 hours, full journeyman takes four years and 6,000 hours, and applicants who assume they are the same thing discover the gap when they try to sit the master exam.
Maryland HVAC license: frequently asked questions
Do you need an HVAC license in Maryland?
Yes, for residential and commercial work alike, under Business Regulation Article 9A and COMAR 09.15. Maryland licenses the individual through a six-tier ladder from apprentice to master, and any business performing HVACR work needs a licensed master or limited contractor acting as its qualifying individual. There is no small-job dollar threshold that exempts you.
How long does it take to become a master HVACR contractor in Maryland?
About seven years on the standard route: four years and 6,000 hours as an apprentice to qualify for the journeyman exam, then three years as a journeyman with 1,875 hours in the final year to sit for master. The narrower tiers arrive sooner, journeyman restricted at three years and 1,875 hours, and limited contractor after two years as a journeyman with 1,000 hours in the prior year.
How much does a Maryland HVAC license cost?
The state fees are unusually small: $12 apprentice, $25 journeyman, $94.50 master, so climbing the entire ladder costs about $131.50 in license fees spread across seven years. The real costs sit elsewhere, in PSI exam fees at each level and the $300,000 general liability plus $100,000 property damage insurance that every classification except journeyman must carry.
Does Maryland accept out-of-state HVAC licenses?
Yes, Maryland has reciprocity with Virginia and Delaware, so a licensed journeyman or master from either state can apply for the Maryland equivalent instead of re-testing. Reciprocity covers the examination, not the insurance and business requirements, which still apply in full once you contract in Maryland.
