HVAC License in Massachusetts: Fees, Requirements & Startup Costs
Quick answer: Massachusetts has no single statewide HVAC business license. Covered refrigeration work on refrigerant-containing systems of ten tons or greater is regulated by the Office of Public Safety and Inspections, Bureau of Pipefitters, Refrigeration Technicians, and Sprinkler Fitters, under 528 CMR. A business doing that work needs a Refrigeration Contractor license, which has a non-refundable $150 application fee according to the Refrigeration Contractor application page. The individual qualifier needs a Refrigeration Technician license, with a $75 application fee. Smaller residential systems fall outside that refrigeration scope, and gas fitting, electrical, and plumbing scopes need their own licenses.
Who licenses what
Start by sorting the work the business will actually sell. The state refrigeration credential covers refrigerant-containing systems of ten tons or greater, as defined in 528 CMR 2.02. Typical smaller residential systems sit outside that definition, which means the refrigeration license is not the whole answer for a residential service company. The official sources reviewed for this page do not list a single statewide residential HVAC business license or a fee tied to one.
The remaining scopes are licensed individually. Gas fitting, electrical, and plumbing work each require their respective licenses in Massachusetts. A business that installs furnaces, runs gas lines, or makes electrical connections needs the matching credentials for those tasks, held by the right individuals, in addition to or instead of the refrigeration credential.
The two refrigeration licenses
The Refrigeration Contractor license is the business-side credential. It allows a regular place of business and the employment of licensed workers, but only for covered refrigeration work on systems of ten tons or greater. The applicant must already hold a Refrigeration Technician license, and 100 hours of additional refrigeration training from an approved school is required.
The Refrigeration Technician license is the individual qualifier’s credential. It authorizes covered refrigeration work and allows the holder to supervise apprentices employed by a Refrigeration Contractor. The in-state path requires 6,000 hours as a licensed Refrigeration Apprentice under a Massachusetts Refrigeration Contractor. Education requirements include a high-school diploma or equivalent, EPA Section 608 Universal certification, and 450 hours of approved refrigeration study listed on the application page.
Both routes run through an exam administered by OPSI. The official sources reviewed for this page do not list the exam fee, so budget it as an unknown rather than assuming a figure.

Experience timing and the 2026 transition
The 6,000-hour apprenticeship requirement is the long pole for a new business. Hours accumulate only under a Massachusetts Refrigeration Contractor, so the owner path and the hiring path both depend on an existing licensed contractor. 528 CMR 11.00 carries an education and experience transition effective November 9, 2026. Applicants who will test near that date should confirm which prerequisite set applies to them before submitting an application.
Bond, insurance, and renewal
The official sources reviewed for this page do not list a surety bond requirement for either refrigeration license. They also do not list an insurance requirement, so confirm both directly with the Bureau before quoting work. Renewal terms, renewal fees, and continuing education hours were likewise not established from the reviewed pages; renewal fees are not part of the year-one startup figure in any case.
Local permits and inspections
Municipal building and mechanical permit rules apply to residential installations. No official page reviewed for this page establishes a universal local HVAC contractor license, but cities and towns still control permits and inspections for the job address. Ask each municipality which work needs a permit, who may apply, and how inspections are scheduled. A state refrigeration license does not set city permit policy.

Fees at a glance
The Refrigeration Contractor application fee is $150, and the Refrigeration Technician application fee is $75. Both are non-refundable and both apply only to covered refrigeration work on systems of ten tons or greater. Exam, issuance, and renewal charges are not listed in the reviewed sources, so a startup budget should treat those as open items. Edit the preset below for the actual vehicle, tooling, and insurance quote. The startup costs page explains why those choices move the opening number.
