Does New York Require an HVAC License? Who Licenses HVAC Work Instead

No. Our research found no statewide New York HVAC license for technicians or contractors, and no state HVAC exam or continuing-education requirement: HVAC-related licensing is done by cities and counties.

In New York City, for example, the Department of Buildings' skilled-trade license list names Electrician, High Pressure Boiler Operating Engineer, Master Plumber and Master Fire Suppression Piping Contractor, Oil Burner Equipment Installer, Rigger, Sign Hanger, Welder and the other trades it licenses, and there is no general HVAC license on it.

What does apply statewide is the federal layer: under 40 CFR 82.161, anyone who could reasonably be expected to violate the integrity of a refrigerant circuit while maintaining, servicing, repairing or disposing of appliances containing regulated refrigerants must pass an exam from an EPA-approved technician certification program.

Our research found no state ladder to climb: the credentials run in parallel, each scoped to one system type.

The FDNY Q-01 Refrigerating System Operating Engineer certificate is the refrigeration credential — in New York City, any refrigerating system that needs an FDNY permit must be supervised while operating by a Q-01 holder.

The DOB Oil Burner Equipment Installer license covers oil-fired heating equipment in two classes: Class A covers any oil-burning equipment, and Class B covers equipment using domestic-grade fuel oils No. 1–4.

Gas piping for HVAC equipment is plumbing work in New York City: it falls under the Licensed Master Plumber, and a worker doing that gas piping needs a DOB Gas Work Qualification.

EPA 608 is a federal certification, not a New York license — separate from city and county licensing.

FDNY Q-01 applicants need a high school diploma or GED, EPA Universal Technician Certification, and one of three routes: a NYC High Pressure Boiler Operating Engineer, USCG marine engineer or Professional Engineer license; a 200-hour Refrigeration Operating Engineer course from an FDNY-certified school with at least 25 hours of field or shop work; or 1 year of qualifying practical experience within the preceding 3 years.

The DOB Gas Work Qualification splits into full — a passed gas work exam plus registered journeyman plumber status, or a NYS registered training program plus 1 year of NYC experience, or 5 years under a Master Plumber (1 in NYC) — and limited, which needs 6 months under a Licensed Master Plumber plus a 16-hour DOB-approved gas course or enrolment in a NYS DOL-approved plumbing apprenticeship.

DOB fees: the written exam application (LIC41) costs $585 and the practical (LIC42) $530, and the Oil Burner Equipment Installer license is $100 with a $75 renewal on a 3-year term.

DOB practical exams for the High Pressure Boiler Operating Engineer and Oil Burner Equipment Installer are not held in July and August, and candidates have 24 months from passing the written test to pass the practical.

Our research found no state HVAC exam: the exams belong to the local credential.

FDNY runs the Q-01 exams in two parts: the Z-51 computer exam, with a $60 application fee, and — after passing it — the Z-52 practical exam at $225, with up to three practical attempts at $225 each.

The Department of Buildings runs its own written and practical license exams: the LIC41 written application costs $585 and covers Master Plumber, Master Fire Suppression Piping Contractor, Oil Burner Equipment Installer, High Pressure Boiler Operating Engineer and the Gas Work Qualification written exam, while the LIC42 practical costs $530.

Our research does not describe the content outline of either exam, so check the exam materials FDNY and DOB publish before you study.

Renewal follows the issuer.

The DOB Oil Burner Equipment Installer license renews every 3 years at $75.

The FDNY Q-01 renewal requires a 7-hour live A2L refrigerant training course from an FDNY-approved refrigeration school — live means in person or virtual — except holders who took the FDNY computer test after January 1, 2025.

Above the local credentials, our research found nothing to renew: no state HVAC license and no state HVAC continuing-education requirement.

If a city or county where you work has its own HVAC credential, ask that office what renewal takes.

Our research did not find any New York HVAC reciprocity agreement, and our research found no statewide license for one to attach to.

Recognition of an out-of-state license is therefore a local question: ask the building or licensing department where you will work what it accepts, in experience, exams and fees, before you assume an out-of-state license carries over.

License records sit with the office that issued them, and our research found no statewide search.

DOB-issued New York City licenses such as Master Plumber and Oil Burner Equipment Installer are checked through DOB's Check License Status tool at nyc.gov/buildings, and Westchester County runs a Trade Licenses Search for its county plumbing and electrical licenses.

Our research captured no FDNY certificate lookup, so confirm a Q-01 holder directly with FDNY.

Two New York City agencies issue the HVAC-adjacent credentials our research confirmed: the Department of Buildings (Oil Burner Equipment Installer, Gas Work Qualification, Master Plumber, High Pressure Boiler Operating Engineer) and the Fire Department (the Q-01 certificate).

Westchester County's Department of Consumer Protection licenses plumbers and electricians county-wide, but its trade-license page lists no HVAC license — an absence we read from that page's scope, not a county statement.

County licensing does exist: Westchester law requires home improvement contractors to hold a county license, though our research did not establish whether HVAC work falls under that license.

On the business side, our research found no state HVAC contractor license; the research cited above points to New York City HVAC companies working under those local credentials, and we did not confirm whether the city requires a separate home improvement contractor license for HVAC work.

Outside New York City and Westchester, our research did not survey other cities and counties: ask the building or licensing department where the work will be done.
