Rhode Island HVAC License Requirements (2026)

The Rhode Island Department of Labor and Training Division of Professional Regulation (RI DLT) licenses HVAC trades under R.I. Gen. Laws § 28-27 as three separate disciplines: Pipefitter (Class I unlimited, Class II limited), Refrigeration Technician, and Sheet Metal Worker. Rhode Island does not issue a single combined "HVAC license"; instead, a full-service HVAC contractor typically holds both a Pipefitter license (for hydronic heating and boilers) or Refrigeration license (for cooling and heat pumps) and a Sheet Metal license (for ductwork). Each discipline has Journeyperson and Master levels and any refrigerant work additionally requires federal EPA Section 608 certification.

Regulatory Oversight

Rhode Island Contractors Registration and Licensing Board / Department of Labor and Training Professional Regulation (CRLB / DLT) administers and enforces this credential under the authority of R.I. General Laws Title 5 Chapter 65 (Contractors Registration); Title 5 Chapter 6 (Electricians); Title 5 Chapter 20 (Plumbers); Title 28 Chapter 27 (Pipefitters and Refrigeration). The Contractors Registration and Licensing Board (CRLB) registers residential contractors and licenses commercial roofers. The Department of Labor and Training (DLT) Division of Professional Regulation licenses electricians, plumbers, pipefitters, refrigeration technicians, and sheet metal workers — the trade licenses required for HVAC work in Rhode Island.

Who May Apply

At a minimum the applicant has to be 18 years old and supply a valid Social Security Number. No Rhode Island residency requirement.

Good moral character

The RI DLT Mechanical Trades Board reviews every applicant for good moral character and prior trade discipline.

Background investigation

Mandatory disclosure of criminal history and prior disciplinary actions.

Required Experience and Education

Eligibility requires 4 years of Journeyperson Refrigeration or Pipefitter II: four years (8,000 hours) of supervised experience through a RI DLT-registered apprenticeship plus 576 hours of related classroom instruction. Pipefitter I (unlimited) requires five years. Master level requires two additional years of licensed journeyperson experience., documented and independently verifiable. Payroll, tax, project, and supervisor records are the usual proof the board will accept.

Accepted proof of experience or eligibility

RI DLT Apprenticeship Completion Certificate
Employer experience verification forms signed by a licensed master in the discipline
W-2 payroll records covering the qualifying period
EPA Section 608 certification card

Education substitution

Graduates of RI DLT-approved HVAC/R technology programs may receive partial credit toward the experience requirement at the Mechanical Trades Board's discretion.

Examination Requirements

The licensing examination is delivered by PSI Services LLC (under contract to RI DLT). All of the following parts must be cleared prior to issuance:

Rhode Island Journeyperson Refrigeration/Pipefitter Examination — IMC, IFGC, ASHRAE 15, RI mechanical code amendments — 80 questions, 240 minutes, passing score 75%
Rhode Island Master Refrigeration/Pipefitter Examination — mechanical code, business and law, calculations, plan reading — 100 questions, 300 minutes, passing score 75%

Examination fee: $75 examination fee per attempt paid to PSI.

Retake policy: Failed examinations may be re-taken by paying a new $75 PSI fee.

Insurance and Financial Requirements

This credential carries no state-level surety bond requirement under the cited sources. Individual jobs may still trigger a permit or public-works bond, which should be verified before bidding.

General liability

Individual HVAC trade licenses do not require liability insurance. Master-level contractors operating an HVAC business must register the business with RI DLT and carry liability insurance.

Workers' compensation

Workers' compensation is mandatory for any HVAC business with one or more employees.

Additional financial requirements

No financial statement requirement for individual trade licenses.

Licensing Fees

Fee	Amount
Application (non-refundable)	$75
Examination	$75
Initial license	$96
Renewal (every 2 years)	$96

Keeping the License Current

Renewal of the Rhode Island HVAC License (Pipefitter I/II, Refrigeration, Sheet Metal) comes due every 2 years. As cited, the renewal fee stands at $96. Lapsed licenses may be reinstated within one year by paying a late fee; longer lapses require re-examination.

Continuing education: Continuing education in the current Rhode Island-adopted mechanical code is required each two-year renewal cycle.

Reciprocity and License Transfer

The NASCLA Accredited Examination is not accepted by Rhode Island for this classification.

Reciprocal State	Accepted Exam	Conditions
No formal bilateral reciprocity agreements identified.

Rhode Island has no formal HVAC reciprocity. Out-of-state licensees must apply, document experience, and sit for the Rhode Island examination in the applicable discipline.

Application Process, Step by Step

Choose the discipline. Decide between Pipefitter (boilers, hydronic heating), Refrigeration (cooling, heat pumps), or Sheet Metal (ductwork). Full-service HVAC typically requires two of the three.
Enroll in a registered apprenticeship. Register with RI DLT Apprenticeship and join a four- or five-year program in the chosen discipline.
Complete 8,000+ hours and 576 classroom hours. Log supervised experience under a licensed master and finish classroom instruction.
Obtain EPA Section 608 certification. Federal refrigerant handling certification is required for any refrigeration or air conditioning work.
Apply for the Journeyperson exam. File the RI DLT application with apprenticeship documentation, EPA 608 card, and $75 exam fee.
Pass the PSI Journeyperson exam at 75%. Score 75% or better on the 80-question trade examination.
Advance to Master and register the business. After two additional years of licensed journeyperson experience, pass the Master exam and register the HVAC contractor business with RI DLT.

Document Checklist

The items below are the ones worth confirming before the application is filed with CRLB / DLT:

Frequent Application Errors

Drawn from the board instructions and sources cited on this page, the pitfalls below are the ones most likely to slow down or sink a Rhode Island HVAC application.

Assuming one license covers all HVAC

Rhode Island splits HVAC into Pipefitter, Refrigeration, and Sheet Metal. Holding only one may leave you unable to legally install a full system.

Skipping EPA 608

Federal Section 608 is required before any refrigerant work. RI DLT will not issue a Refrigeration license without it.

Informal helper hours

Only hours accrued in a RI DLT-registered apprenticeship under a licensed master count toward the experience requirement.

Wrong Pipefitter class

Applying for Pipefitter II when the intended work requires Pipefitter I leaves you unable to touch industrial or high-pressure systems.

Not registering the business

A Master-level trade license authorizes the individual. Operating as an HVAC contractor requires a separate business registration with RI DLT.

Questions Applicants Ask

Does Rhode Island issue a single HVAC license?

No. Rhode Island licenses HVAC trades as three separate disciplines: Pipefitter (Class I or II), Refrigeration Technician, and Sheet Metal Worker. Full-service HVAC contractors typically hold more than one.

Is EPA Section 608 required?

Yes. EPA Section 608 certification is federally required for any work involving refrigerants and must be obtained before RI DLT issues a Refrigeration license.

What is the difference between Pipefitter I and Pipefitter II?

Pipefitter I is unlimited and covers high-pressure systems, industrial process piping, and large commercial boilers. Pipefitter II is limited to smaller systems and typical residential/light commercial hydronic heating.

How many hours of experience does Rhode Island require?

8,000 hours (four years) for Refrigeration and Pipefitter II Journeyperson, 10,000 hours (five years) for Pipefitter I, plus 576 classroom hours in all cases.

How often does the license renew?

Every two years. Renewal requires continuing education in the current mechanical code as set by the Mechanical Trades Board.
