What license tiers does Massachusetts offer?
The refrigeration ladder has three rungs: apprentice (registered, no exam), technician (6,000 hours plus 250 coursework hours plus exam) and contractor (2,000 technician hours plus 100 coursework hours plus exam, allows running a business and employing licensed staff). Parallel ladders exist for sheet metal workers under their own board, and gas fitting credentials run through the plumbers and gas fitters board.
What is the Massachusetts HVAC exam like?
Both the technician and contractor exams are written exams administered through OPSI after your application is approved, passing at 70 percent. Exam details arrive with your approval rather than through a public candidate bulletin, so build your study plan around the approved coursework and the mechanical code. Licenses arrive by mail a few weeks after a pass.
How much does an HVAC license cost in Massachusetts?
State application fees are modest: reported at $40 for apprentice, $75 for technician and $150 for contractor, verify current amounts with OPSI. The real cost is the required education, 250 approved hours for technician and 100 more for contractor, at OPSI approved schools whose tuition varies widely. Union apprenticeships typically cover the classroom side.

What does it take to start your own HVAC business in Massachusetts?

Note that apprentices you employ only accrue valid hours while you hold the contractor license and they stay registered with DAS, so lapses hurt your crew, not just you.
What most guides get wrong about Massachusetts
The phrase Massachusetts HVAC license is a trap: the state has never issued one. What it issues is a refrigeration license with a 10 ton threshold, which means most residential work needs no state credential while commercial work needs the full apprentice to technician to contractor ladder. The mistake that costs people years is logging hours without being registered: apprentice hours only count while you are licensed with OPSI, registered with the Division of Apprentice Standards and employed by a licensed refrigeration contractor, all three at once.
Massachusetts HVAC license: frequently asked questions
Do you need a license to do HVAC work in Massachusetts?
Not a general one, because Massachusetts does not issue an HVAC license. The state licenses refrigeration work on systems of 10 tons or more of capacity, plus separate credentials for sheet metal work and gas fitting. Most small residential AC work falls under no state license at all, while commercial refrigeration is tightly regulated.
What is the 10 ton rule in Massachusetts?
State law requires a refrigeration license for installing, repairing, replacing or maintaining any refrigerant containing part of a refrigeration or air conditioning system of 10 tons or more. Below that threshold the state license does not apply, which is why many residential techs in Massachusetts hold only EPA 608. Anyone building a commercial career needs the state ladder.
How do you become a licensed refrigeration technician in Massachusetts?
Register as an apprentice with OPSI and the Division of Apprentice Standards while working for a licensed refrigeration contractor, then document 6,000 apprentice hours plus 250 hours of approved coursework and pass the technician exam. An approved school certificate and your DAS registration are required with the application.
What other licenses matter for HVAC careers in Massachusetts?
Sheet metal workers have their own board and license ladder covering ductwork and air distribution, and gas fitting on heating equipment runs through the plumbers and gas fitters board. Many Massachusetts HVAC careers stack two credentials, commonly refrigeration plus a gas fitter card, depending on the work mix.
