Rhode Island · HVAC licensing · official-source guide
Yes. Rhode Island licenses HVAC work statewide through the Department of Labor and Training, Division of Professional Regulation, under the Mechanical Board. Contracting requires a master license such as Refrigeration Master I or II, or Pipefitter Master 1 or 2. Journeypersons cannot be self employed. Fees, exams and birthday renewal are set by R.I. Gen. Laws Chapter 28-27.

The Rhode Island Department of Labor and Training issues every HVAC license used in this state. Inside DLT, the Division of Professional Regulation takes the applications, schedules the exams and holds the discipline file. The Mechanical Board, created by R.I. Gen. Laws 28-27-1.0, is responsible for licensing and regulating masters, journeypersons and apprentices in the pipefitting, air conditioning and refrigeration, sprinkler fitting and sheet metal trades. The same statute tells the board to advise DLT on the correct license for heating, cooling, air distribution, process piping, fire protection and venting systems. Self-contained home appliances and piping covered by the plumbing law sit outside that authority. DLT describes Professional Regulation as handling licensing, testing, registration and discipline for over 30,000 people in 67 trade jobs, across seven licensing boards with 56 members total. The mechanical trades get their own chief investigator inside the unit. No Rhode Island city or town issues a competing HVAC contractor license. Providence, Warwick, Cranston and Pawtucket all inspect mechanical work and sell permits, but the credential itself comes from DLT, whose Professional Regulation office is at 1511 Pontiac Avenue in Cranston. For a contractor that is good news. One DLT master license lets you bid and sign work in every Rhode Island municipality without a second local card. What varies between towns is the permit counter, not the license you carry.

Rhode Island puts the right to contract in the master tier. Under R.I. Gen. Laws 28-27-5, nobody may run a mechanical trades business, sign installation or service contracts, or advertise that they will install pipefitting, refrigeration, air conditioning or air distribution systems without a valid DLT license. For cooling and refrigeration the relevant classes are Refrigeration Master Class I, which is unlimited, and Refrigeration Master Class II, which the state rules cap at comfort cooling systems up to 20 tons, product cooling up to 3 tons, or freezing up to one horsepower. For heating the classes are Pipefitter Master Class 1, which is unlimited, and Pipefitter Master Class 2, which is limited to heating only, caps commercial and residential heating installations at 500,000 BTU, and bars process piping. Above Refrigeration Master I and Pipefitter Master I sits Master Mechanical Contractor, an unlimited heating, cooling and process license the board awards only to someone who has held both Rhode Island Pipefitter Master I and Rhode Island Refrigeration Master I for ten years each. All four master classes can be self employed and must keep a regular place of business. A separate Contractor Master limited license exists for a degreed principal who runs one company but does not perform the work personally, and that applicant has to file a current workers compensation policy and a current general liability policy for the entity.
Rhode Island draws a hard line between who may hold the contract and who may do the work. Refrigeration Journeyperson Class I and Class II, and Pipefitter Journeyperson Class I and Class II, all carry the same clause in the state rules: cannot be self employed. A journeyperson technician in Rhode Island works for a licensed master. That single rule shapes hiring here. If you want an HVAC company of your own in this state you are not looking for a journeyperson card, you are looking at the master ladder. Refrigeration Master Class I requires that you first hold a Rhode Island Refrigeration Journeyperson I license for one year, or a Refrigeration Master II license for one year. Refrigeration Master Class II requires three years holding a Rhode Island Refrigeration Journeyperson Class II. Pipefitter Master Class 1 and Class 2 mirror those waits on the pipefitting side. Class II journeypersons are also boxed in by scope, not just by employment. A Pipefitter Journeyperson II is limited to heating installations and cannot touch process piping. That person can climb to Class I only by reentering the apprenticeship program for an additional 6,000 hours of on the job training plus 432 hours of related instruction, working under a Pipefitter Master I or a Journeyperson I. The refrigeration side uses the same 6,000 and 432 hour upgrade path.

Every mechanical license in Rhode Island is built on registered apprenticeship, not on loose field time. The state rules define an apprentice as someone under a written agreement, working under direct supervision of a licensed master or journeyperson, inside a program registered with the Rhode Island Department of Labor and Training. The range is a minimum of 4,000 hours over a two year program up to 10,000 hours over a five year program, with at least 144 hours of trade related schooling each year. Two years of study at an institution the department recognizes may be deducted from the apprenticeship. The unlimited classes sit at the top of that range. Refrigeration Journeyperson Class I and Pipefitter Journeyperson Class I each require a minimum of 10,000 hours of on the job training with at least 144 hours of trade related schooling per year. The Class II limited licenses require a minimum of 4,000 hours plus 288 hours of trade related schooling. Sheet Metal Journeyperson Class I sits at 8,000 hours. Ratios are written into the rules and they differ by trade. Pipefitting and refrigeration Class II programs allow one apprentice per three licensed people. Sheet metal Class II allows one apprentice per one licensed person, while Sheet Metal Journeyperson Class I work allows one per five. Those ratios decide how fast a Rhode Island shop can grow its own bench.

R.I. Gen. Laws 28-27-14 requires the department to provide and conduct examinations three times each year for applicants whose pipefitter, refrigeration, air conditioning, fire protection sprinkler or sheet metal application is already on file. The Division of Professional Regulation runs the exams with the aid of the board of examiners, at places inside Rhode Island chosen for the reasonable convenience of the applicant. Test materials are preserved for three months after the test date. Because the sittings are fixed at three per year rather than on demand, an application filed at the wrong point in the calendar can push a Rhode Island start date out by months. Plan the filing date backward from when you need to be signing contracts. If you fail, section 28-27-16 lets you take any of the three examinations scheduled during the year, and every retest requires payment of a separate test fee. The test fee itself is 75.00 for every class in the statutory table except Master Mechanical Contractor, which carries no test fee because the board awards it on an evaluated resume rather than a further exam. Subject matter is set by the state rules. Master applicants are expected to know the Rhode Island classes below their own, blueprint reading and layout, controls and wiring, and the current International Code Council State Building Code mechanical volume, SBC-4. DLT publishes the mechanical application forms on its Professional Regulation forms page.

The fee schedule is statutory, in R.I. Gen. Laws 28-27-17, and it lists a test fee, a license fee and a renewal fee for each class. Master Mechanical Contractor is 480.00 for the license and 480.00 to renew, with no test fee listed. Contractor Master, Pipefitter Master I, Refrigeration Master I, Fire Protection Sprinkler Fitters Master I and Sheet Metal Contractor each run 75.00 to test, 240.00 for the license and 240.00 to renew. The limited master classes are cheaper: Pipefitter Master II and Refrigeration Master II are 75.00 to test, 96.00 for the license and 96.00 to renew. On the journeyperson side, Pipefitter Journeyperson I, Refrigeration Journeyperson I, Fire Protection Sprinkler Fitters Journeyperson I and Sheet Metal Worker Journeyperson are 75.00 to test, 72.00 for the license and 72.00 to renew, while Pipefitter Journeyperson II and Refrigeration Journeyperson II are 75.00 to test, 60.00 and 60.00. Watch one wrinkle before you budget. R.I. Gen. Laws 28-27-4.4 still states a master mechanical contractor license fee of two hundred forty dollars, while the 28-27-17 fee table adopted in 2024 shows 480.00 in both the license and renewal columns. Confirm the current charge with the Division of Professional Regulation before you send payment. A company license under 28-27-6 costs the same as the corresponding master license.

Rhode Island does not renew mechanical licenses on a calendar quarter or a common statewide date. Under R.I. Gen. Laws 28-27-17, a license issued to a holder born in an odd year expires on that person's birthday in odd years, and a license issued to a holder born in an even year expires on that person's birthday in even years. In practice that is a two year cycle keyed to your own date of birth, so two masters in the same Rhode Island shop can have renewal dates two years apart. Renewal is made on or before the expiration date on payment of the appropriate fee. The state rules add that all fines and penalties must be paid in full before any license is issued. Missing the date gets expensive quickly. R.I. Gen. Laws 28-27-17.1 imposes a twelve dollar per month administrative assessment for the first two years of delinquency, on top of the outstanding license fees. If the license is not renewed within two years of expiration it is forfeited, and the only way back is to sit the test again for a new license. The state rules repeat the point: a license lapsed under two years can be reinstated on payment of all fees due, but past two years the applicant is subject to reexamination. Diary the birthday. Rhode Island offers no grace beyond the assessment.

Rhode Island treats the mechanical trades differently from plumbing on this point. The Bureau of Pipefitters, Refrigeration Technicians, Sprinklerfitters, Sheet Metal Workers and Oil Heat Contractors rules, 260-RICR-30-15-2, set no continuing education hour requirement as a condition of renewing a pipefitter or refrigeration license, and R.I. Gen. Laws 28-27-17 conditions renewal only on payment of the fee by the expiration date. By contrast DLT publishes a plumber continuing education agreement and a Rhode Island plumbing CE provider application on its forms page, and nothing equivalent appears in the Mechanicals list, which carries only the apprentice completion and examination form, the mechanical application form and the mechanical corporation form. That is not an invitation to stop learning. The rules require Master Mechanical Contractor applicants to show the chief administrator that up to date knowledge of the trades is maintained through periodic schooling of a general nature and trade seminars. Every master and journeyperson class carries an express knowledge requirement covering Rhode Island workers compensation and temporary disability law under Title 28, state tax withholding under Chapter 44-30, apprenticeship law under Chapter 28-27, prevailing wage under Title 37, the federal Davis Bacon Act, state occupational safety law under Chapter 28-20, federal OSHA, and the International Code Council State Building Code mechanical volume SBC-4 at 510-RICR-00-00-4. An inspector can test that knowledge on a job site.

Rhode Island does not hand out mechanical licenses on paper reciprocity. What an out of state license buys you is the right to sit the Rhode Island exam without first grinding through a Rhode Island apprenticeship. The state rules say it the same way for each class. An out of state Master Class I Refrigeration license will allow the applicant to be tested for the Refrigeration Master Class I Rhode Island license, and a copy of the license must be attached to the application. The same clause appears for Pipefitter Master Class 1, Pipefitter Master Class 2, Refrigeration Master Class II, and both journeyperson tiers on each side. If your home state does not issue the matching class, the rules give an experience route instead. For Refrigeration Master Class I and Pipefitter Master Class 1 that is a notarized resume showing six years of experience, one of which is as a contractor. For the Class II master licenses it is a notarized resume showing six years of experience, three of which are as a contractor. Massachusetts and Connecticut refrigeration technicians crossing the line to work Providence or Woonsocket jobs should budget for the exam calendar, since testing happens three times a year. The DLT online system also carries a search for apprentices, sponsors and reciprocals, which is the practical place to check how your record was entered.

Rhode Island's mechanical statute and rules do not set a dollar figure for general liability coverage or a surety bond amount for a pipefitter or refrigeration master license. What the rules do require is proof of coverage in one place and working knowledge of the rules everywhere else. An applicant for the Contractor Master limited license must supply a copy of the current workers compensation insurance policy of the entity to be licensed and a copy of its current general liability insurance policy, along with the employer identification number, two affidavits from authorized officers and two character references. Every other master and journeyperson class carries the standing requirement that contractors understand Rhode Island workers compensation law and temporary disability insurance law under Title 28. Workers compensation is the coverage that actually bites in Rhode Island. R.I. Gen. Laws 28-36-1 requires every employer subject to the workers compensation chapters to secure that liability, either by insuring with an authorized carrier, by satisfying the director of labor and training of financial ability and posting security or a bond, by a combination of the two, or by joining an authorized group self insurance fund. Temporary disability insurance is a separate Rhode Island payroll obligation that out of state owners routinely miss. Confirm your exact limits with the Division of Professional Regulation and your carrier rather than assuming a neighboring state's numbers carry over.
Rhode Island runs a second construction regulator, the Contractors' Registration and Licensing Board inside the State Building Office, and most trades doing residential or commercial construction here must register with it. HVAC is carved out. The board's own general contractor registration page lists the work that commonly needs registration, including roofers, siding installers, drywall installers, masons, painters and insulation installers, then gives separate guidance telling anyone in the electrical, HVAC, mechanical or plumbing trades to contact the Rhode Island Department of Labor and Training instead. The statute backs that up. R.I. Gen. Laws 5-65-3 provides that no subcontractor licensed by another in state agency under section 5-65-2 is required to register, provided the work is performed under the purview of that license. The practical test is scope. A DLT mechanical master doing heating, cooling, refrigeration and air distribution work is covered by the DLT license. The same company adding general remodeling, framing, roofing or siding to the same job is doing work outside the purview of that license and should confirm its registration status with the board before bidding. The board can be reached at 401-921-1590. Getting this wrong is not academic: 5-65-3 also requires the permit issuer to record a contractor registration number on the permit or the basis for the exemption, so the question surfaces at the municipal counter.
Rhode Island writes its display rules into the statute, which makes this an enforcement issue rather than a style choice. R.I. Gen. Laws 28-27-19 requires a certificate of license at all times in every place in the state from which a pipefitter, refrigeration, air conditioning, fire protection sprinkler or air distribution business is conducted, showing the name, address, state license number, classification and any limitations. The same section requires that all vehicles used in those businesses be identified as regulated by the bureau and display, in lettering no smaller than three inches, the contractor category, the license number and the company name. The state rules repeat the three inch minimum for vehicles and places of business. R.I. Gen. Laws 28-27-5 goes further and reaches your marketing. A master must carry the license on their person at all times while working, and must affix the master's license number to any advertisement, to any contract they execute, to any bid they file with a consumer, and to any permit required for the work. Read literally that covers a Rhode Island HVAC company's website, its truck wrap, its yard signs, its printed estimates and its Google listing copy. On the registration side of the house, 5-65-3 fines a registered contractor one hundred dollars per offense for using the word license in advertising when only registered. A DLT master is genuinely licensed and may say so.

Enforcement in Rhode Island is unusually local. R.I. Gen. Laws 28-27-26.1 makes it the duty of the director of labor and training and of state and local inspection authorities to enforce the mechanical trades chapter, and gives local building and related inspectors who do day to day inspection the primary responsibility for it. Those inspectors can demand production of licenses and certificates on any site where covered work is happening, and can investigate and file complaints. The state board of examiners holds concurrent enforcement authority and the same right to demand licenses on site. So the person most likely to catch unlicensed mechanical work in Providence or Cranston is the municipal inspector standing in the basement, not a state auditor months later. Consequences run on two tracks. R.I. Gen. Laws 28-27-21 lets the director revoke or suspend a license or impose a fine after a board hearing for grounds that include knowingly hiring or aiding an unlicensed person, loaning your license so someone else can work, and willfully violating city or town ordinances governing this work. R.I. Gen. Laws 28-22-2 requires fines to be paid within thirty days of notice or the license is revoked, and gives the director injunction power in superior court against an unlicensed violator. Under 28-27-30 violations may be enjoined in superior court and violators may be ordered to pay the complainant's reasonable attorney fees.

A Rhode Island license does not replace a permit. R.I. Gen. Laws 28-27-20 preserves the right of any city, town or the state to require inspection and permits for installation, maintenance, repair and servicing of pipefitting, refrigeration, air conditioning, fire protection sprinkler and air distribution systems, and to collect fees. Where a permit is required, the statute makes it a condition of issuance that the contractor's license number and a copy of the contractor's license be affixed to the permit, which the contractor must sign, and the permit must be obtained before the installation starts. For emergency equipment or appliance replacement and repair, the permit application must be submitted by the next business day to the office of mechanical inspection. Providence takes building, mechanical, electrical, plumbing, moving and demolition applications through its e-permitting portal, and the city notes that an account already created for the state level e-permitting system works on the Providence site. Boilers add a state layer on top. The mechanical rules require permits from the Rhode Island Department of Labor boiler division on commercial heating installations of 200,000 BTU and above and residential installations of 400,000 BTU and above, and a Pipefitter Master Class II may pull those permits only up to 500,000 BTU. Above 500,000 BTU the job needs a Pipefitter Master Class I. R.I. Gen. Laws 28-27-29 also confirms that a state boiler permit is required for commercial boiler installations over 200,000 BTU.

Rhode Island gives consumers a free public search, and smart contractors point customers straight at it. The Division of Professional Regulation runs an online system where anyone can look up a trade license by trade, license number, name, city and state, or telephone number. The result page also flags violations. The same system carries a separate violations search that returns violation history by license number, name, city and state, company name or telephone number, plus an application status search and a search covering apprentices, sponsors and reciprocals. That violations search is the part worth knowing about. In many states a consumer can confirm a license exists but cannot see a discipline history without filing a records request. In Rhode Island the history is two clicks away, so a clean record is a marketing asset and an old unresolved complaint is a liability that shows up during the buying decision. Use it deliberately. Put your DLT license class and number on the estimate, on the truck and on your website, and tell the customer where to check it. Statute already requires the number on advertisements, contracts, bids and permits under R.I. Gen. Laws 28-27-5, so the number is public anyway. Inviting verification converts a compliance obligation into proof. If your record shows something stale, clear it with the division before your competitors point a customer at the same screen.
A Rhode Island DLT license is not the whole picture for anyone who opens a refrigerant circuit. EPA regulations at 40 CFR Part 82, Subpart F, under Section 608 of the Clean Air Act, require that technicians who maintain, service, repair or dispose of equipment that could release ozone depleting refrigerants into the atmosphere be certified. That obligation is federal and applies in Rhode Island regardless of which DLT class you hold. EPA publishes four test areas: Core, Type 1 for small appliances, Type 2 for high pressure equipment, and Type 3 for low pressure equipment. A residential Rhode Island service technician working split systems and heat pumps is typically in Type 2 territory, while a Providence chiller job pulls in Type 3. EPA does not issue the certification cards itself. Certification comes from approved certifying organizations, and EPA maintains the list of technician certification programs along with the steps and the organizations that can replace a lost card. Keep both credentials current and keep them separate in your records. The DLT license controls whether you may contract, advertise and pull a mechanical permit in Rhode Island. Section 608 certification controls whether the individual technician may legally touch the refrigerant. A Rhode Island master who lets an uncertified helper recover refrigerant has a federal problem that a state license will not cure.

A master class license from the Rhode Island Department of Labor and Training. Refrigeration Master Class I or II and Pipefitter Master Class 1 or 2 can all be self employed under the state mechanical rules. The journeyperson classes cannot be self employed, so a journeyperson card alone will not let you contract in Rhode Island.
Class I is unlimited as to restriction on work. Class II is limited by the state rules to comfort cooling installations up to 20 tons, product cooling up to 3 tons, or freezing up to one horsepower. Class II also requires three years holding a Rhode Island Refrigeration Journeyperson Class II before you can test.
On your own birthday. R.I. Gen. Laws 28-27-17 expires licenses held by people born in odd years on their birthday in odd years, and licenses held by people born in even years on their birthday in even years. That is a two year cycle keyed to your date of birth, not a common statewide renewal date.
R.I. Gen. Laws 28-27-17.1 adds a twelve dollar per month administrative assessment for the first two years of delinquency plus the outstanding license fees. If you go more than two years past expiration the license is forfeited and can only be regained by taking the test again for a new license.
Yes. R.I. Gen. Laws 28-27-19 requires all vehicles used in the business to display the contractor category, license number and company name in lettering no smaller than three inches. The state mechanical rules repeat the three inch minimum and apply it to your place of business as well.
Yes. R.I. Gen. Laws 28-27-5 requires a master to affix the master's license number to any advertisement, to any contract executed, to any bid filed with a consumer, and to any permit needed for the work. The master must also carry the license on their person while working.
Generally no for the mechanical work itself. The board's registration page directs HVAC, mechanical, electrical and plumbing trades to the Department of Labor and Training, and R.I. Gen. Laws 5-65-3 exempts a subcontractor licensed by another in state agency when the work falls under that license. Work outside that scope is a different question.
Three times a year. R.I. Gen. Laws 28-27-14 requires the department to provide and conduct examinations three times each year for applicants already on file, at locations within Rhode Island. If you fail, section 28-27-16 lets you sit any of the three scheduled examinations, and each retest requires a separate test fee.
The statutory table in R.I. Gen. Laws 28-27-17 lists 75.00 to test, 240.00 for the license and 240.00 to renew. Pipefitter Master I carries the same figures. The limited Class II master licenses are 75.00 to test, 96.00 for the license and 96.00 to renew.
Not directly. Under the state mechanical rules an out of state license of the matching class lets you apply to be tested for the Rhode Island license, with a copy of that license attached. If your state has no matching class, a notarized resume showing six years of experience substitutes, with one or three of those years as a contractor depending on class.
Local building and related inspectors have primary responsibility under R.I. Gen. Laws 28-27-26.1 and can demand production of licenses and certificates on any site where covered work is happening. The state board of examiners holds concurrent authority to do the same. Fines go unpaid at the risk of revocation under R.I. Gen. Laws 28-22-2.
The state mechanical rules require boiler division permits for commercial heating installations of 200,000 BTU and above and residential installations of 400,000 BTU and above. A Pipefitter Master Class II can pull those permits up to 500,000 BTU. Above that the work needs a Pipefitter Master Class I.
