Washington to Rhode Island: master HVAC technician license reciprocity
Washington does not issue a statewide master HVAC technician license, so there is nothing to transfer. Here is Rhode Island's standard path for out-of-state applicants.
Your origin state does not issue a statewide license at this level, so there is no license to transfer. The destination's standard out-of-state path is shown; expect to meet it in full.
Reference only, not legal advice. Rules change; confirm with the licensing board before you apply. Full disclaimer.
Out-of-state master or contractor admitted to the Rhode Island Refrigeration Master exam (all states)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
A master HVAC technician or HVAC/refrigeration contractor licensed in any other state applies to DLT for the Refrigeration Master 1 (code 002) or Master 2 (code 003) examination on the Mechanical Trade application, with a copy of the out-of-state license and an official license verification, a notarized employer statement on company letterhead detailing all work experience, a copy of government ID and the $75 non-refundable fee, filed at least 15 days before the exam date. R.I. Gen. Laws § 28-27-10(3) accepts, in place of one year as a Rhode Island-licensed journeyperson, 'an affidavit or other reasonably satisfactory evidence showing the laws of another state specifying that person as a ... refrigeration/air conditioning ... master', and 260-RICR-30-15-2 § 2.12.C states that 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'; if the origin state has no Master Class I license, a notarized resume showing six years' experience, one as a contractor, accompanies the application (Master Class II: six years, three as a contractor). The master exam is not waived and must be passed with a score of 70 or better; the applicant is then invoiced for the $240 two-year Master I license fee ($96 for Master II). Unlike the electrical trade, an out-of-state master does not have to hold the Rhode Island journeyperson license first.
DLT publishes no separate business or law exam for the master license; the master exam is a single DLT-administered examination. Whether DLT accepts an out-of-state 'HVAC contractor' or 'master HVAC' title as the equivalent of a refrigeration/air-conditioning master under § 28-27-10(3) is decided on the license verification; no list of accepted titles is published. The DLT fee table lists both 'Refrigeration Master 1' and 'Contractor Master Refrigeration' (CMR) at the same fees. The CMR is a separate limited license under R.I. Gen. Laws § 28-27-6.2 and DLT regulation § 2.7: it lets an officer or principal of one business bid, advertise and pull permits for that business, but not personally install or repair. A Master I who wants to contract as a firm also files the Mechanical Corporation application. Processing time is not published.

How Rhode Island licenses master HVAC technicians
Rhode Island master HVAC technician · “Refrigeration Master Class I (RM1, unlimited)”
Statewide license
Rhode Island's master-level HVAC credential is the Refrigeration Master Class I (RM1), the unlimited refrigeration/air-conditioning master license issued by DLT to an individual after passing the master examination; a Master Class I may be self-employed and, under R.I. Gen. Laws § 28-27-4, a master refrigeration contractor performs refrigeration/air conditioning work through a regular place of business personally or through employed journeypersons. The Refrigeration Master Class II (RM2) is the limited version (comfort cooling to 20 tons, product cooling to 3 tons, 1 hp freezing). A Rhode Island applicant must have held a Rhode Island Refrigeration Journeyperson I license for one year (or a Master II for one year; Master II requires three years as a Journeyperson II). Rhode Island has no reciprocity agreements and no exam waiver, but R.I. Gen. Laws § 28-27-10(3) and DLT regulation § 2.12.C allow an applicant whose out-of-state law designates them a refrigeration/air-conditioning contractor or master to sit the Rhode Island master exam directly on the strength of that license, or, where the origin state has no Master Class I license, on a notarized resume showing six years' experience including one as a contractor. Fees are a $75 application fee and a $240 two-year license fee for Master I ($96 for Master II); the DLT fee table also lists a 'Contractor Master Refrigeration' at $240 and a no-test Master Mechanical Contractor ($480) reserved for those with ten years each as Pipefitter Master I and Refrigeration Master I. Licenses renew every two years on the licensee's birthday.
Why Washington has nothing to transfer
Washington master HVAC technician
No individual license at this level
Issued by Washington State Department of Labor & Industries (contractor registration)
Washington has no master HVAC or mechanical contractor license and no HVAC trade or business exam. A business that installs or services heating, ventilation, air conditioning or refrigeration systems must register with the Department of Labor & Industries as a general contractor or as an HVAC specialty contractor, which requires a Department of Revenue business registration, a continuous surety bond of $30,000 (general) or $15,000 (specialty) or an equivalent assignment of savings, a general liability insurance policy and a $150.20 application fee; unlike plumbing, electrical, elevator, boiler and asbestos work, HVAC carries no additional education, examination or licensing requirement. Electrical work on the equipment must be done by 06A or 06B HVAC/Refrigeration specialty electricians, or by a licensed electrical contractor, and refrigerant handling requires federal EPA Section 608 certification. Registration does not evaluate or credit an out-of-state master HVAC license, and L&I publishes no HVAC reciprocity; a master HVAC licensee who only wants to work for an employer needs no Washington license, while one who wants to contract independently simply registers.
