  22. Continuing Education

Learning a trade requires hard work and determination. You can’t rush the process, but the time you put into learning how to become an HVACR technician or contractor can lead to a career that is long-lasting, lucrative, and fulfilling. There are 425,200 heating, air conditioning, and refrigeration mechanics and installers nationwide, according to the U.S. Bureau of Labor Statistics, and Maine employs 2,110 of them. 

Employment is projected to grow 8% from 2024 to 2034 throughout the country, adding more than 40,000 of these skilled workers to the ranks. In Maine, that growth rate is expected to be lower — projected at -1% — according to CareerOneStop, the U.S. Department of Labor’s job search website.

Contractors struggle to find skilled tradesmen like plumbers, electricians, and HVACR or mechanical professionals. According to the Associated General Contractors of America, “Construction employment in Maine in July 2025 totaled 34,700, a decrease of 500 (-1.4%) from July 2024 and an increase of 4,000 (13%) from February 2020.” So, if you get the training you need, you should have a variety of jobs to choose from when you’re ready.

A large part of what HVAC contractors and technicians do is replace and repair existing HVAC systems. As more emphasis is placed on energy efficiency and reducing pollution, systems need to be retrofitted, upgraded or replaced entirely to comply with these new standards. Licensing requirements for HVAC contractors vary from state to state and, in some cases, from locality to locality. Maine licensure is a bit more complicated than other states.

Licensing Requirements for HVAC Contractors in Maine

Is a license required for HVAC technicians and contractors in Maine? Yes, but licensing for HVAC work in Maine is not a typical statewide license for HVAC technicians or HVAC contractors. 

Instead the Office of Professional and Occupational Regulation in Maine oversees the Maine Fuel Board and issues licenses for various types of HVAC work.

To get started in the HVAC field in Maine, you often only need to meet employer expectations and eventually get licensed in the specialty in which you’d like to practice. There are federal certification requirements to consider as well. If you want to become an HVAC technician, you’ll need to have a certification from the U.S. Environmental Protection Agency to legally handle refrigerants. You may also need to pass a certification exam, depending on the license classification.

  • A trade license is proof of your experience and skill.

  • Having a license protects your company and customers.

  • A license gives you a competitive advantage in the job market.

  • It also increases your earning potential.

What Is the Mean Wage for an HVAC Technician in Maine?

The annual mean wage for HVAC mechanics and installers in Maine is $63,580, according to the U.S. Bureau of Labor Statistics. However, that salary can increase as you acquire more experience. An HVAC technician salary database, shared with ServiceTitan by Payscale.com, projects the median HVAC technician salary will increase nationally in 2025 by 3.44% for entry-level workers, 3.46% for intermediate level, 3.62% for senior level HVAC professionals, and 3.53% for supervisors. In Maine, those salary projections are:

Entry (<2 years): $52,500

Intermediate (2-4 years): $63,800

Senior (4-7 years): $74,900

Supervisor (>7 years): $88,200

The meaning of a “mean” and “median” can be confusing. Here is the difference:

  • Mean tells you the mathematical average.

  • Median tells you the point at which 50% of workers make less and 50% make more, and is usually a better indicator of what most people actually earn.

Salaries can vary widely depending on the city where you work and other factors like education, certifications, additional skills, and the number of years you have spent in your profession. If you choose to start an HVAC business, this blog can give you an idea of what you can expect to make and what factors will influence that number.

How Long Does it Take to Get an HVAC Contractors License in Maine?

Many of the Maine license classifications require minimal training, and you may only need to complete an application to get started. For a Journeyman Oil Burner and/or Solid Fuel Technician license, you need to work as an apprentice for at least one year. For a Master Oil Burner and/or Solid Fuel Technician license, you need four years of experience, with at least two as a licensed journeyman. 

Completing an apprenticeship usually takes four to five years, but the great news is that as an apprentice, you begin earning a wage from the very beginning, and that compensation goes up each year as you acquire more training and knowledge until you are fully licensed at the journeyperson level.

Maine HVAC Training Programs and Schools

Since the state of Maine doesn’t require you to obtain education experience, you most likely will not choose to get a postsecondary degree. However, many people choose to complete education programs to gain additional experience. 

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). There are no programs in Maine accredited by either organization, but there are some well-respected options for enrollment statewide. 

Here's a list of the best HVAC schools in Maine:

  • Niche: 2026 Best Colleges with HVAC and Refrigeration Engineering Technician Degrees in Maine

Maine’s Community College System offers several HVAC programs. Southern Maine Community College offers an Associate Degree in Heating, Air Conditioning, Refrigeration & Plumbing that takes 4.5 full-time semesters and is 62 credit hours. SMCC also offers a Certificate in Heating program that takes half that time. Eastern Maine Community College in Bangor has an Associate of Applied Science degree program in Refrigeration, Air Conditioning & Heating.

Tuition: You can expect to spend about $2,880 per semester for in-state tuition. You can find the breakdown of tuition and fees for SMCC at this link.

Apprenticeship: There are different kinds of apprenticeship options in Maine. You can apply for a union training program like the ones offered through Maine Plumbers and Pipefitters Local 716 in Augusta. The apprenticeship program is five years long, meets all requirements of the state and is completely free to students. The cost is covered by the union contractors who pay into the trust, and students are placed with one of those contractors to work. As part of these apprenticeships, you will also complete the EPA certification and the Certified Employee Training Program for propane certification.

Or you could choose a non-union training program through a trade organization like Plumbing, Heating, Cooling Contractors Association of Maine. Or you could simply apply for one of the apprentice positions listed on ZipRecruiter or Indeed to see if an employer will sponsor you.

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 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 Maine HVAC License Work in Any Other State?

No, the state of Maine does not have reciprocal agreements with any other states for any of the licenses related to heating, ventilation, air conditioning and refrigeration.

What Are the Reciprocity Requirements for an HVAC License in Maine?

To recap, Maine doesn’t have reciprocal agreements with any states. Therefore, out-of-state credentials will not qualify you for a Maine HVAC license by reciprocity. If you are coming from any other state, you will need to meet all licensing requirements for your specific classification.

HVAC Specific Requirements: EPA Certification

Throughout the country, including in Maine, 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, or your employer 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. All apprenticeships will include this preparation and testing.

Take 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 Refrigerants. 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.

Core Exam

For all certifications, you must pass the “Core Section” of the EPA certification exam. It covers the following topics:

  • Ozone depletion

  • Clean Air Act and the Montreal Protocol

  • Section 608 regulations

  • Substitute refrigerants and oils

  • Refrigeration

  • The Three R’s (Recover, Recycle, Reclaim)

  • Recovery techniques

  • Dehydration evacuation

  • Safety

  • Shipping

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 Maine

All HVAC licenses in Maine must be renewed exactly two years from your initial licensure date. The renewal fee is the same as the initial license fee. If your license lapses more than 90 days, you will face a $50 penalty upon renewal. 

Are There HVAC Scholarships in Maine?

Yes, there are HVACR scholarships in Maine. Options include:

Additionally, the Maine Technical Education Center offers financial assistance for students who enroll in the organization’s HVAC Professional Certification program.

How Can Someone Verify My HVAC License in Maine?

Your HVAC license can be verified by potential clients or employees in Maine via the state’s Administrative, Licensing & Management System. You can search by name, license number, or licensing agency. 

When Can an HVAC License Be Suspended in Maine?

A suspended HVAC license means that the license holder is temporarily prohibited from practicing their trade legally. Some of the common reasons that Maine HVAC licenses can be suspended are:

  • Fraud

  • Professional incompetence

  • Misleading or deceptive practices

  • Criminal convictions

  • Aiding unlicensed individuals

  • Failure to comply with regulations

  • Practicing on a lapsed license

  • Willful or repeated violations of regulations governing HVACR professionals

Licensees can also face disciplinary action if they fail to report changes in business or personal information to the board or fail to respond to an investigation or complaint.

What Are the Penalties for Unlicensed HVAC Work in Maine?
