Maryland HVAC License: How to Become an HVACR Contractor in Maryland
Table of Contents
We all need skilled professionals to help us keep our homes and businesses comfortable using heating and air conditioning systems. HVACR professionals need comprehensive training to know how to install and repair the advanced technology used in today’s HVAC systems. Most choose to complete some kind of formal education program at either a trade-vocational school or attend college or complete an approved apprenticeship before jumping into the field.
There are over 340,000 Heating, Air Conditioning, and Refrigeration Mechanics and Installers in the United States, according to the Board of Labor and Statistics, and 7,320 work in Maryland.
Climate control and refrigeration systems wear out and break down and need to be repaired. Also, with more of an emphasis being placed on energy efficiency and reducing pollution, systems need to be retrofitted, upgraded or replaced entirely to remain compliant.
Trained HVACR professionals are in high demand to keep up with this thriving industry. In fact, according to the U.S. Bureau of Labor Statistics, employment of heating, air conditioning, and refrigeration mechanics and installers is projected to grow 4 percent from 2019 to 2029 — adding more than 15,000 of these skilled workers to the ranks.
And if you’re looking to join them, there’s more good news! According to the Associated General Contractors of America, contractors are hiring. In the 2020 AGC-Autodesk Workforce Survey, 60% of firms in the U.S. had unfilled hourly craft positions on June 30, 2020.
The licensing requirements for HVAC workers and contractors vary from state to state and in some cases from locality to locality. In Maryland, you’ll need a statewide license.

The facts the Commission shall consider in the denial, reprimand, renewal, suspension, or revocation of a license when an applicant or licensee is convicted of a felony or misdemeanor are: the nature of the crime; the relationship of the crime to the activities authorized by the license; with respect to a felony, the relevance of the conviction to the fitness and qualification of the applicant or licensee to provide home improvement services; the length of time since the conviction; and the behavior and activities of the applicant or licensee before and after the conviction.
Each applicant for a home improvement contractor's license must meet the Commission's financial solvency guidelines based upon the applicant's personal assets, not business assets. Any applicant who does not meet the financial solvency guidelines may purchase a surety bond or obtain an indemnitor.

How to Get an HVAC License in Maryland
The first step in your HVACR career path in Maryland is to get your HVACR Apprentice License. You don’t need to be enrolled in an apprentice program to get your license, but you will need your license before you are allowed to start your training.
WORK EXPERIENCE: Before you can apply for your Journeyman license, you must gain the necessary three years of experience. There are three ways to do that.
You can find and complete an apprenticeship program.
Earn a degree of certificate from an approved trade school.
Work under the supervision of a licensed HVACR Contractor; or some combination of #2 and #3.
The Maryland Apprentice and Training Program website lists approved programs. If you go this route, you can apply for an Original Journey or Journey Restricted License WITHOUT examination. This is for applicants who have successfully completed a program approved by the Maryland Apprenticeship and Training Council and have a Department of Labor Certificate of completion. You have two years from the date on your certificate to obtain your license.
The other two options require you to take a licensing exam before applying for your license. You can successfully complete an approved HVACR degree or certificate program in combination with job experience supervised by a licensed HVAC Contractor or accumulate three years of experience in the field in or out of state that the board deems acceptable. The board will accept up to three years of formal HVAC education, so you could technically meet the three-year requirement without any hands-on training, but this is very unusual.
APPLY TO TAKE EXAMINATION: Once you’ve fulfilled the work experience requirements, you may apply to take the license exam. The MD Journeyworker exam is for the Unrestricted Journey License. It costs $150 and entitles the licensee to provide installation and maintenance services in all of the areas of HVACR work under the supervision of a Master. Each of the Journeyman Restricted licenses (Air Conditioning, Forced Air, Hydronic, Refrigeration, and Ventilation) cost $50 and entitles an individual to perform one or more specialized HVACR services while under the direction and control of a licensed contractor.
TAKE LICENSING EXAM: The state of Maryland has contracted with PSI Testing Services to administer the exams. To be eligible to register for an examination, you have to satisfactorily complete the required work experience. PSI will review the application to determine that an applicant is eligible by meeting all license requirements. The Candidate Information Bulletin provides all the information about the tests, the requirements, and the process. Every test requires a minimum passing grade of 70%.
APPLY FOR LICENSE: You can apply for your license online through Maryland’s Department of Labor Electronic Licensing online platform. This is a link to the Original Journey/Journey Restricted License Application after you have successfully passed the exam or after you have successfully completed an HVACR related apprenticeship in a program approved by The Maryland Apprenticeship and Training Council.
ADDITIONAL WORK EXPERIENCE: If you choose to pursue any of the Master licenses, you will need to accrue additional work experience. The state says to apply for the Unrestricted Master License you must have been licensed as a journeyman and regularly and principally employed to provide all areas of HVACR services for at least three years of active experience under the direction and control of an HVACR master, and worked a minimum of 1,875 hours in the year prior to applying for the master license. For any of the restricted licenses, you will need the same years and hours of active experience in the specialty area for which you are applying.
An applicant not meeting any of the above qualifications may also apply to take a Master Restricted examination. To be eligible, the applicant must document at least six (6) years of qualifying HVACR experience.
APPLY TO TAKE EXAMINATION: Once you’ve fulfilled the work experience requirements, you may apply to take the license exam. The Master HVACR Contractor exam is for the Unrestricted Master License. It costs $150 and entitles the licensee to provide installation and maintenance services in all of the areas of HVACR work. Each of the Master Restricted licenses (Air Conditioning, Forced Air, Hydronic, Refrigeration, and Ventilation) cost $50 and entitles an individual to perform installation and maintenance work in one or more areas of HVACR work.
TAKE LICENSING EXAM: The state of Maryland has contracted with PSI Testing Services to administer all of the exams including the Master level. Again, the Candidate Information Bulletin provides all the information about the tests, the requirements, and the process. Every test requires a minimum passing grade of 70%.

The following must appear on the insurance certificate:
Your name must appear on the certificate of insurance.
Your general liability insurance coverage must be at least $300,000.
Your property damage liability insurance coverage must be at least $100,000.
The combined amount of the general liability and property damage insurance must be at least $400,000.
The policy number and expiration date of the policy must appear on the certificate of insurance.

APPLY FOR LICENSE: You can apply for your Master, Master Restricted, or Limited Contractor license online as well. This is a link to the HVACR – Original License Application that you would use after you have successfully passed the exam and met the other requirements.
How Long Does it Take to Get an HVAC Contractors License in Maryland?
It will take a minimum of three years to qualify to take the Journey Level licensing exam in Maryland and then an additional three years working as a Journeyman to qualify for the Master level. However, even if part of that time is dedicated to classes, you will likely be working and earning money the whole time.

Maryland HVAC Training Programs and Schools
Because HVAC technology is becoming more and more complex, getting some kind of formal training can be very helpful and is generally preferred by employers.
In fact, most HVAC technicians nationwide hold some kind of post-secondary degree or certificate. There are currently two main organizations that approve HVAC programs and schools nationwide: HVAC Excellence and the Partnership for Air-Conditioning, Heating, Refrigeration Accreditation (PAHRA). However, currently, there are no programs accredited by either organization in Maryland, possibly because the state encourages the apprentice route instead.
If you decide that you want formal education before joining the workforce, there are several schools that offer HVAC degrees. The Community College of Baltimore County offers an associate of applied science degree in HVAC as well as several certificate HVAC programs. You can also find HVAC programs at Montgomery College, Brightwood College, and other community colleges. If you want a bachelor’s degree in the HVAC field, the top universities in the state include the University of Maryland in Baltimore and John’s Hopkins Whiting School of Engineering. There are also many more options for online training like Fortis or Penn Foster.
Here are three great lists of the best HVAC schools in Maryland:
Niche: 2021 Best Colleges with HVAC and Refrigeration Engineering Technician Degrees in Maryland
A certificate program can take a matter of months or you can get a two-year degree at a technical or community college or a four-year degree.
Tuition: The cost of tuition depends on the program you choose. According to Education Cost Helper an HVAC certificate can cost as little as $1,200. Tuition for an associate’s degree can cost $15,000. A bachelor’s degree from a state university can cost about $40,000 and private universities, like John’s Hopkins, can be as much as $50,000 per year.
If you choose to forego a more traditional college degree, a formal apprenticeship can give you the hands-on and classroom instruction you need. This is the route the Maryland Board encourages most. You can use the Maryland Apprenticeship Locator to find the one that’s right for you and is Board approved.
Program Prerequisites: You must be at least 18 years old and have a high school diploma or a GED.
On-the-Job Experience: While on the job, you will need to have good customer service skills, be detail-oriented, have some mechanical capability, and be physically fit because the job can include some heavy lifting and hours of walking, standing, and working in tight spaces.

Does My Maryland HVAC License Work in Any Other State?
Yes, Maryland has reciprocity agreements with both Virginia and Delaware. You may apply for a reciprocal license if you are currently licensed in either of these neighboring states. Reciprocal licensing is permissible if the individual:
Meets the qualifications of Maryland's HVACR law;
Holds an active license in good standing in the other state;
Holds a license that is equivalent to the Maryland HVACR license; and
Became licensed in the other state after meeting, in that state, requirements for licensure that are at least equivalent to the licensing requirements of this state, including the number of years of work experience required by the Maryland law.
Environmental Protection Agency (EPA) Certification: Everywhere throughout the country, including Maryland, federal-level EPA regulations under Section 608 of the Clean Air Act require that technicians who maintain, service, repair, or dispose of equipment that could release refrigerants into the atmosphere must be certified. EPA Section 608 HVAC Certification is required for any professional who conducts refrigerant line-pressure tests or handles or adds refrigerant to existing air conditioning systems.
Most training programs can direct you to how and where to get that certification and many even make it part of the curriculum, or your employer/apprenticeship will require you to get it before handling refrigerant. You can also go to EPA.gov and key in 608 Certification in the search bar to find out which institutions in your state offer certification programs.
Certification Exam: You must acquire your EPA Certification from an approved organization. A list of these organizations can be found on the EPA’s website. There are four types of EPA Certifications for Refrigerant. They allow for different levels of certification for different scopes of work.
Type I: For servicing small appliances containing five pounds of refrigerant or less.
Type II: For servicing high-pressure units that contain five pounds or more of refrigerant (including most small commercial and residential systems).
Type III: For servicing or disposing of low-pressure appliances.
Universal: For servicing all systems and appliances covered under Types I, II, and III. Generally more useful than targeting any one specific certification.
For all certifications, you must pass the “Core Section” of the EPA certification exam. It covers the following topics:
Clean Air Act and the Montreal Protocol
Section 608 regulations
Substitute refrigerants and oils
The Three R’s (Recover, Recycle, Reclaim)
National HVAC Certifications
Other certifications can help you demonstrate your proficiency to potential employers and clients. North American Technical Excellence (NATE) certification, ASHRAE (American Society of Heating, Refrigeration and Air-Conditioning Engineers) certification, and other professional certifications are not required but can add to your marketability as a service provider and therefore increase your opportunity to make more money.
Other Requirements Unique to Maryland
To keep your state-issued license current, Maryland requires you to renew it every two years. The renewal fee is $20.
There is no continuing education requirement for licensed HVAC Contractors in Maryland at this time.
