New York to Massachusetts: master HVAC technician license reciprocity
New York does not issue a statewide master HVAC technician license, so there is nothing to transfer. Here is Massachusetts'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.
Refrigeration Contractor by examination with out-of-state license credit (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 OPSI for the Refrigeration Contractor examination online through the My License portal or by mail. The Massachusetts prerequisites are 2,000 hours held and used under a Massachusetts Refrigeration Technician license plus 100 hours of post-apprenticeship refrigeration training at an approved school; the application form lets the applicant instead certify 'I held and used a refrigeration license in another jurisdiction for not less than 2000 hours' and that the 100 hours of additional training were taken at an institution in another jurisdiction, with employer and school documentation, and states that such an application may be forwarded to the Bureau, which may allow the candidate to sit for the examination. Under 528 CMR 11.07(1) the Bureau decides whether the out-of-state license and its underlying experience and education are substantially equivalent and may grant partial credit or deny the petition. The applicant also submits proof of age (18+) and a 2x2 photo with the $150 non-refundable fee, is notified about four to eight weeks after receipt, and must pass the contractor exam at 70% (a failing candidate reapplies). The exam is not waived for any state because the Bureau has no reciprocity agreement; the license renews for $75.
528 CMR 11.03 states the master prerequisite as 2,000 hours 'as a Massachusetts Journeyman Refrigeration Technician', while the Bureau's own contractor application accepts 2,000 hours under a refrigeration license from another jurisdiction if the Bureau agrees; the form governs in practice but the outcome is at the Bureau's discretion. The Bureau's published materials do not say whether it may instead require the applicant to obtain the Massachusetts Refrigeration Technician license first. No separate business or law examination is published for this license. The contractor how-to page and form list only the $150 application fee; no separate exam fee or initial license fee is published.

How Massachusetts licenses master HVAC technicians
Massachusetts master HVAC technician · “Refrigeration Contractor (Master Refrigeration Technician)”
Statewide license
Massachusetts' highest personal HVAC-type credential is the Refrigeration Contractor license, which M.G.L. c. 146, § 81 calls the 'master refrigeration technician' and 528 CMR 11.03 the 'Master Refrigeration Technician/Contractor'. It is issued by the Bureau of Pipefitters, Refrigeration Technicians and Sprinkler Fitters (OPSI) to an individual who has held and used a Massachusetts Refrigeration Technician license for at least 2,000 hours and completed 100 hours of additional Bureau-approved refrigeration training; it allows the holder to establish a refrigeration business and employ licensed technicians and apprentices, and the license number must appear on vehicles and invoices. The applicant pays a $150 non-refundable application fee and must pass the OPSI contractor exam at 70%; the license renews for $75. There is no general HVAC or mechanical contractor license in Massachusetts; hydronic heating contractors hold a Master Pipefitter license and oil-burner firms are certified by the Department of Fire Services. The contractor application lets an out-of-state applicant substitute 2,000 hours under a refrigeration license held in another jurisdiction and 100 hours of training taken elsewhere, subject to the Bureau agreeing to let the candidate sit the exam; the exam itself is never waived because the Bureau has no reciprocity agreements.
Why New York has nothing to transfer
New York master HVAC technician
Licensed by cities and counties
New York issues no statewide master HVAC, mechanical or HVAC contractor license; the Department of State licenses none of the construction trades, so the master-level credential exists only where a city or county has created one, and most have not. The only examined, person-holdable HVAC license in the state is Buffalo's Heating Contractor license from the Board of Heating Examiners (age 21, two years of heating installation experience, a quarterly written exam, a $10,000 bond, $1,000,000 liability insurance, $50 exam fee and $500 a year), which covers heating and process systems but not air-conditioning-only work. New York City has no HVAC or mechanical contractor license at all (the DOB licenses oil burner installers and the FDNY certifies refrigerating system operating engineers, but installation and service of HVAC systems needs no license), and the suburban counties regulate the trade through home improvement contractor licensing of the business: Westchester has required 'all HVAC professionals' to hold its home improvement license since July 1, 2025 ($750 application, no exam), Nassau's home improvement license ($650 for two years plus $50, five years of experience, no exam) covers central heating and air-conditioning work, and Suffolk's ($200 application and $200 a year, $500,000 insurance, no exam) covers HVAC ductwork. An out-of-state master HVAC license has no state-level recognition and none of these jurisdictions publishes reciprocity for it; a contractor from another state obtains the local business license (or, in Buffalo, sits the heating contractor exam) in each jurisdiction where they will work.
How local licensing works in New York
How local licensing works. With no state HVAC board, each jurisdiction that regulates the trade does so under its own code, usually as a business license with insurance and experience requirements rather than a trade exam. Buffalo is the exception with an examined heating contractor license.
New York City. The Department of Buildings issues no HVAC, mechanical or refrigeration contractor license; mechanical work is done under permits without a trade license, and the general contractor registration ($300 for three years) applies only to builders of one- to three-family homes. Oil-fired equipment must be installed by a DOB-licensed Oil Burner Equipment Installer (Class A or B; written exam $585, practical exam $530, $100 license for three years), and any refrigerating system that needs an FDNY permit must be supervised by a holder of the FDNY Q-01 Refrigerating System Operating Engineer Certificate of Qualification (EPA Universal certification, a 200-hour course or one year of qualifying experience or a boiler engineer, marine engineer or PE license; $60 plus $225 exam fees; three-year renewal $15). Neither recognizes out-of-state HVAC licenses.
Buffalo. City Code Chapter 238 makes it unlawful for any person to install, erect, alter, repair, service, reset or replace any heating or process system without a license from the Board of Heating Examiners; the separate City contractor license 'does not allow for plumbing, heating, cooling or electrical work'. Applicants must be at least 21 and have two years of practical experience installing heating equipment, a recognized school course plus one year, or be a graduate engineer; they submit photo ID, employer letters and a list of twenty completed installations to the Office of Fuel Devices, and if approved sit the Heating Contractor's Examination (offered roughly every three months, covering local ordinances and ASHRAE material). Classes: I (oil, gas or solid fuel), II (gas or solid fuel), III (wood-burning fireplaces and stoves). Fees: $50 non-refundable testing fee, $500 license, $500 annual renewal; a $10,000 bond to the City and certificates of $1,000,000 general liability and workers' compensation insurance are required. The license may be held by an individual, partnership or corporation. No reciprocity provision.
Rochester. Licenses stationary engineers and refrigeration operators (plant operation), electricians and plumbers; no HVAC contractor license.
Westchester County. The June 2025 amendment to the Consumer Protection Code requires 'all HVAC professionals' to be licensed through the Department of Consumer Protection as of July 1, 2025; the vehicle is the county Home Improvement Contractor license ($750 application fee effective January 1, 2026, $100 optional expedite, roughly 60 business days of document verification and background investigation, no exam). The county's examined trade licenses cover only plumbers and electricians.
Nassau County. Contractors installing or replacing 'central heating or air conditioning systems' in residential property need the county Home Improvement license: five years of recent verifiable experience, an establishment in New York State, liability, property damage and workers' compensation insurance, $650 for a two-year license plus a one-time $50 restitution fund contribution, $110 late renewal fee; no exam.
Suffolk County. Home improvement contracting expressly includes 'ductwork for heating, ventilation and air-conditioning systems'; the county Home Improvement license requires public liability and property damage insurance of at least $500,000 per occurrence and workers' compensation, a $200 application fee and $200 annual license fee ($50 temporary 90-day license); employees of licensed contractors are exempt; no exam.
Out-of-state holders. No New York jurisdiction publishes a reciprocity or endorsement path for out-of-state HVAC contractor or master licenses. Buffalo requires its own exam; the counties require their own business license regardless of any license held elsewhere; New York City requires no HVAC license at all.
