How Do You Get an HVAC License in Maine?
Maine has no general HVAC or refrigeration technician license in our research — the license path runs through heating fuel instead.
The Maine Fuel Board licenses oil burner and solid fuel technicians at apprentice ($40), journeyman ($100) and master ($200) levels, each renewed every two years, plus propane and natural gas technicians ($100, two-year term) and helpers ($20, no exam).
For air-conditioning and refrigeration work we found no state license; the federal requirement that covers that work is EPA 608 certification.

No general HVAC/refrigeration license in our research.
What Maine licenses statewide is heating-fuel work, through the Maine Fuel Board.
The Maine Fuel Board, which replaced the state's separate oil and solid fuel and propane and natural gas boards.
Apprentice, Journeyman and Master Oil Burner / Solid Fuel Technician, plus Propane and Natural Gas Technician and Helper.
Our research found no A/C-refrigeration license.
Journeyman oil burner: 1 year as a licensed apprentice, or a board-approved 160-hour course (75 hours lab) plus 6 months as an apprentice, or a 320-hour community-college heating course (150 hours lab).
Master: at least 4 years licensed, at least 2 as a journeyman.
Computer-based, at Maine test centers or remotely, after board approval; the board links a ProV candidate information bulletin.
The journeyman and master oil burner / solid fuel exams require 70% to pass and are split by authority.
Gas technicians complete board-approved training first.
Oil burner / solid fuel licenses renew every two years ($40 apprentice, $100 journeyman, $200 master).
CE was not covered by our research — ask the board.

Does Maine require a state HVAC license?
Not with a general HVAC license.
Our research found no Maine HVAC or refrigeration technician license: the state's licensing portal lists no HVAC or refrigeration board, so the absence is our inference from that list rather than a statement in the rules.
What Maine does license statewide is the heating-fuel side.
The Maine Fuel Board licenses oil burner and solid fuel technicians at apprentice, journeyman and master levels, and propane and natural gas technicians and helpers; it replaced the state's separate oil and solid fuel and propane and natural gas boards.
Confirm your situation with the department before working without a state card.
What license levels does the Maine Fuel Board issue, and what can each legally do?
The Fuel Board's oil burner and solid fuel ladder has three rungs.
A licensed apprentice may assist in making oil burner installations, repairs and servicing of oil burning equipment, but only under the direct supervision of a licensed master oil burner technician.
A journeyman works under the indirect supervision of a master.
A master is licensed to engage in the business of installing or servicing oil-burning equipment.
Beyond that, our research found no separate HVAC contractor license: businesses doing oil, solid-fuel or gas heating work rely on individually licensed Fuel Board technicians.
The propane and natural gas technician license carries one or more authorities: delivery, plant operator, tank setter and outside piping, appliance connection and service up to 500,000 BTU, and large equipment over 500,000 BTU; helpers need no exam but must be directly supervised on site.
One crossover is written into Maine's plumbing law: licensed oil burner technicians and propane and natural gas installers may make hot and cold water connections to existing piping in the same room as their installation without a plumbing license.
“this exception only applies to hot and cold water connections to existing piping in the same room where the installation is taking place”
What are the requirements for each level: hours, training, exam and fees?
Fees first: the apprentice oil burner / solid fuel license is $40, the journeyman license is $100 and the master license is $200, each renewed every two years, and a $21 criminal background check fee applies.
To sit the journeyman exam you need 1 year as a licensed apprentice, or a board-approved 160-hour course with 75 hours of lab plus 6 months as an apprentice, or a one-year 320-hour community-college heating course with 150 hours of lab.
The master license takes at least 4 years of licensed experience, at least 2 of them as a licensed journeyman.
On the gas side, the propane and natural gas technician license is $100 on a two-year term and requires a board-approved training program before the exam; a helper license is $20 with no exam.
“Complete at least 4 years of licensed experience. At least 2 of the 4 years of licensed experience must be as a licensed Journeyman.”
Who gives the Maine Fuel Board exams, and what is on them?
The Fuel Board's exams are computer-based, given at several secure test centers in Maine or remotely, and applicants need board approval before scheduling; the board links a ProV candidate information bulletin.
Journeyman and master oil burner / solid fuel exams require a 70% passing score and are split by authority: #1 & #2 oils up to 15 gph, #1 & #2 oils over 15 gph, #4-6 oils, and solid fuel.
Gas applicants must complete a board-approved training program to be deemed qualified to sit for the license examination.
Our research did not capture the content outline itself, so read the ProV bulletin the board links before you schedule.
“Examinations are computer-based examinations. There are several secure test centers in Maine.”
How do you renew, and how many CE hours does Maine require?
The oil burner / solid fuel licenses renew every two years, with the same fees the board lists for the initial license: $40 apprentice, $100 journeyman, $200 master.
The propane and natural gas technician license runs on a two-year term.
On continuing education we can state nothing either way: our research did not capture any CE requirement for Fuel Board licenses, so ask the board what applies before you plan a renewal cycle.
Does Maine accept licenses from other states?
Reciprocity for Maine Fuel Board licenses is not established in our research: we have no record of any out-of-state agreement and no list of partner states for the oil burner, solid fuel, or propane and natural gas credentials.
If you hold one of those licenses from another state, contact the Fuel Board before you apply and ask how it treats out-of-state training, experience and exams.
How do you look up a Maine Fuel Board license?
Through the state's licensee search.
The Fuel Board pages link to it from maine.gov/pfr/professionallicensing, under the 'search for a licensee' link; the exact search-page URL was not confirmed in our research, so start at that address and follow the link.
Search before you take a job with, or hire, anyone claiming a Fuel Board license, and check that the license level and authorities match the work.
What about HVAC certification and EPA 608 in Maine?
The credential that follows refrigerant work is federal.
Under Section 608 of the Clean Air Act (40 CFR 82.161), any person who could reasonably be expected to violate the integrity of the refrigerant circuit while maintaining, servicing, repairing or disposing of appliances containing CFC/HCFC or non-exempt substitute refrigerants must pass an exam from an EPA-approved technician certification program.
The two credentials cover different work: EPA 608 certification attaches to that refrigerant work, while the Fuel Board licenses cover fuel-burning heating.
Our research found no Maine-issued HVAC certification.

Frequently Asked Questions
Do you need a license to do HVAC work in Maine?
It depends on the work.
Our research found no general Maine HVAC or refrigeration technician license; what the state licenses is fuel-burning heating.
The Fuel Board licenses oil burner and solid fuel work through its apprentice, journeyman and master levels, and propane and natural gas work through technician and helper licenses.
Federal EPA 608 certification is required of anyone who could reasonably be expected to violate the integrity of a refrigerant circuit while maintaining, servicing, repairing or disposing of appliances containing regulated refrigerants.
Because the absence of an A/C-refrigeration license is our inference, confirm with the department before working without a state card.
Is there a journeyman HVAC license in Maine?
In our research, the one journeyman license of this kind is for oil burner and solid fuel work: the Journeyman Oil Burner / Solid Fuel Technician license.
It costs $100, renews every two years, and takes 1 year as a licensed apprentice, or a board-approved 160-hour course (75 hours lab) plus 6 months as an apprentice, or a one-year 320-hour community-college heating course (150 hours lab), followed by a 70% exam.
Our research found no journeyman license for air-conditioning and refrigeration work.
How much does an HVAC license cost in Maine?
For the Fuel Board licenses: $40 for an apprentice oil burner / solid fuel license, $100 for journeyman and $200 for master, plus a $21 criminal background check fee, each renewed every two years.
The propane and natural gas technician license is $100 on a two-year term, and a helper license is $20 with no exam.
Exam fees were not captured in our research — check the ProV candidate bulletin the board links.
Do you need EPA 608 certification in Maine?
For refrigerant work, yes — federally.
Under 40 CFR 82.161, anyone who could reasonably be expected to violate the integrity of a refrigerant circuit while maintaining, servicing, repairing or disposing of appliances containing CFC/HCFC or non-exempt substitute refrigerants must pass an exam from an EPA-approved certification program.
It is a certification rather than a Maine license, and it is separate from the Fuel Board licenses that cover fuel-burning heating work.
How do you become a propane and natural gas technician in Maine?
Complete a board-approved training program — the board's FAQ names a national propane association certified employee training program or a board-approved propane/natural gas course — then pass the license exam and apply for the $100 license, which runs on a two-year term.
The license carries one or more authorities: delivery, plant operator, tank setter and outside piping, appliance connection and service up to 500,000 BTU, and large equipment over 500,000 BTU.
Helpers need no exam but must be directly supervised on site.
