Vermont to Rhode Island: master HVAC technician license reciprocity

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.

Vermont has no master HVAC, HVAC contractor, mechanical contractor or refrigeration contractor license and no statewide general contractor license, so a person or firm may install and service heating, cooling, ventilation and refrigeration systems without any state HVAC credential; no Vermont city was found to license the trade either. The credentials that do apply have no master tier: the Division of Fire Safety's gas certification (LP, natural gas or both, $60 for three years, NPGA or AGA training plus the Vermont Energy Goals module) and oil burner installer certification ($60 for three years, NORA Silver or Gold for full installation, Bronze for limited service) are required of every individual who installs, inspects or services fuel-burning equipment under 20 V.S.A. s. 2731, and the Type-S Specialist electrician license in field C3 (refrigeration or air conditioning, air-to-air heat pumps) or A1 (automatic gas or oil heating, ground-source heat pumps) lets a licensee wire that equipment 'as an employee or an independent contractor' for $115 per field, which is the closest thing Vermont has to an HVAC contractor credential. None of these recognizes an out-of-state HVAC or mechanical contractor license: the gas and oil certifications are issued on the national training certificates alone, and the Type-S reciprocity on the electrical application is limited to Maine and New Hampshire electrical licensees. A master HVAC licensee arriving from another state therefore has nothing to transfer; they need federal EPA Section 608 certification for refrigerant work, the gas or oil certification for fuel-burning equipment, a Type-S (or journeyman/master electrician) license for the wiring, and local permits.
