HVAC Contractor License in Rhode Island: Requirements, Qualifier, Bond and Exams

Yes — statewide, and the requirement attaches to people before companies.

No one may contract, advertise or employ others in pipefitting, refrigeration/air conditioning or sprinkler work without a DLT master license, and the master license number must appear on ads, contracts, bids and permits.

A second, separate registration layer applies to contractors working on structures: a person may not undertake, offer to undertake, or submit a bid to do work as a contractor on a structure without a current, valid certificate of registration from the Contractors' Registration and Licensing Board.

Both requirements come from Rhode Island General Laws and run across the state.

Two bodies.

The Department of Labor and Training's mechanical board licenses masters, journeypersons and apprentices in the pipefitting, air conditioning/refrigeration, sprinkler fitting and sheet metal trades — for HVAC work, the relevant trade is air conditioning/refrigeration, where the fee schedule lists Journeyperson I/II and Master I/II classes.

On the business side, a company doing mechanical work without a licensed master as an officer or partner holds a DLT mechanical contractor license, whose fee equals the master fee.

The chapter also names a master mechanical contractor designation, requiring at least 10 years each as a Rhode Island Licensed Pipefitter Master I and a Rhode Island Licensed Refrigeration Master I.

Separately, the CRLB registers every contractor working on structures, and corporations must designate a responsible individual.

Rhode Island's qualifier is a licensed master in the applicable mechanical trade, and the statute gives a business two ways to attach one: a master as an officer or partner who continuously supervises the work, or a DLT mechanical contractor license backed by a master the company continuously employs.

The master credential itself has a fixed pipeline.

A journeyperson refrigeration technician has completed a 10,000-hour registered apprenticeship and passed the refrigeration technician exam, and a master exam applicant must document a Rhode Island journeyperson license held for a minimum of one year — or show an equivalent master license from another state.

The exams our research found are trade exams: the refrigeration technician exam for the journeyperson license, then the master exam, for which an applicant documents the Rhode Island journeyperson license held for at least one year — or an equivalent master license from another state.

Since June 25, 2024, apprentices applying for Rhode Island mechanical licensing exams must complete an applicable registered apprenticeship program in Rhode Island and document it with transcripts and work record books.

Our research did not establish a separate business-and-law exam requirement, and the exam vendor and content outline are not confirmed in our research — ask DLT what the current exams require before you schedule.

The insurance requirement we found comes from the CRLB, not the mechanical board: registrants must carry at least $500,000 combined single limit, bodily injury and property damage liability insurance, plus workers' compensation.

On bonds, our research did not establish a surety bond requirement for Rhode Island HVAC contractors — that is a gap in our research, not a statement that no bond applies — so confirm the current requirement with the CRLB before you bid.

The mechanical fee schedule prices each class as test / license / renewal: a $75 test fee, then $240 license and renewal for Refrigeration Master I, $96 for Master II, $72 for Journeyperson I and $60 for Journeyperson II — and a DLT mechanical contractor license costs the same as the master license.

Mechanical licenses expire on the holder's birthday every two years (odd-year births in odd years, even-year births in even years).

The CRLB registration or renewal fee is $150.

Two gaps: the master mechanical contractor designation's fee is $240 in one section of the statute and $480 in its fee table, and the CRLB's registration term is not stated in our research — confirm both, and any continuing-education requirement, with DLT and the CRLB before you budget.

Our research records no license-to-license reciprocity agreement for Rhode Island mechanical licenses.

The out-of-state route the statute gives sits at the master exam: an applicant can show an equivalent master license from another state instead of the one-year-as-a-journeyperson rule.

That is exam eligibility, not automatic licensure, and our research does not describe how DLT evaluates an out-of-state license beyond it — ask the Department of Labor and Training how yours will be treated.

One more constraint on out-of-state pipelines: since June 25, 2024, apprentices applying for the mechanical licensing exams must complete an applicable registered apprenticeship program in Rhode Island.

The statute's verb is continuous: the contractor-license route requires the company to continuously employ a master at all times while holding the license, and our research did not establish any grace period.

Our research also found no explicit rule on how quickly a departed master must be replaced, and none on whether one master may qualify more than one company — ask DLT both questions before you share a qualifier across related companies.

Plan the replacement pipeline early: a new qualifier needs a master license, which takes the journeyperson license (a 10,000-hour registered apprenticeship and the refrigeration technician exam) plus at least one year holding the Rhode Island journeyperson license — or an equivalent master license from another state in place of that year — and since June 25, 2024 an apprentice in that pipeline must complete a Rhode Island registered apprenticeship to sit the exams.

Two scope limits sit next to the contracting rule.

A master mechanical license lets its holder do sheet metal work only when the AC air-handling equipment is 10 tons or less or the heating equipment does not exceed 250,000 BTUs; larger sheet metal work must be subcontracted to a licensed sheet metal contractor, whose journeypersons complete an 8,000-hour registered apprenticeship.

The chapter also runs a separate P.J.F. (oil burnerperson) line, including a limited Class II journeyperson license that requires at least 160 hours of approved classroom and/or laboratory technical training.
