New York HVAC Technician License: County & City Rules (No State Board)

New York does not issue a statewide HVAC technician license — licensing happens at the county and city level. Who actually licenses HVAC technicians and where to check, verified from official sources.

Requirements at a glance

No New York State license exists (nothing to apply for at the state level): There is no statewide HVAC, air conditioning, refrigeration, heating or mechanical-contractor license in New York, so there are no state requirements to satisfy. New York's two occupational-licensing agencies are the Department of State's Division of Licensing Services (DLS), which states it "oversees the licensure, registration, and regulation of 35 occupations throughout the state" and names each of them (beauty enhancement; real estate; security and secured services; and a miscellaneous group of notary, athlete agent, pet cemetery, telemarketer, central dispatch, ticket reseller, hearing aid dispenser, bedding manufacturer, durable juvenile product manufacturer, automobile broker and health clubs), and the State Education Department's Office of the Professions, whose "New York State Licensed Professions" index lists 36 professions (acupuncture through veterinary medicine). Neither list contains HVAC, air conditioning, refrigeration, heating, mechanical contracting, plumbing or electrical work. Every HVAC credential in New York is issued below the state level.
NYC - who needs the DCWP Home Improvement Contractor (HIC) license, and who does not: In New York City, residential HVAC work is licensed as home improvement, not as a trade. NYC Administrative Code sec. 20-386(2) provides that "[w]ithout regard to the extent of affixation, 'home improvement' shall also include the installation of central heating or air conditioning systems" - so an HVAC install lands squarely inside the home-improvement licensing regime. Section 20-387(a): "No person shall solicit, canvass, sell, perform or obtain a home improvement contract as a contractor from an owner without a license therefor." The license is held by the business, not by each technician: sec. 20-390(3) requires the application to "be filed only by the actual owner of a business," and sec. 20-397(1) exempts "[a]n individual who performs labor or services for a contractor for wages or salary." An employed HVAC technician in NYC therefore needs no DCWP license of their own. Scope note: sec. 20-386(3) defines "building" as "any structure containing no more than four residences or dwelling units."
NYC - licensed-trade and small-job exceptions to the HIC license (NYC Admin Code sec. 20-397): A licensed-trade exception does exist, and it is scope-bound. Section 20-397 ("Exceptions") states that "[n]o contractor's license shall be required" of, among others, "[a] plumber, electrician, architect, professional engineer, or any other such person who is required by state or city law to attain standards of competency or experience as a prerequisite to engaging in such craft or profession ... and who is acting exclusively within the scope of the craft, profession or business for which he or she is currently licensed pursuant to such other law." The exception is written as a category, not as a list of named licenses, and it runs only while the holder acts EXCLUSIVELY within that other license's scope. It does not convert a trade license into home-improvement authority: sec. 20-387(b) provides that "[a] license issued pursuant to this subchapter may not be construed to authorize the licensee to perform any particular type of work or engage in any kind of business which is reserved to qualified licensees under separate provisions of state or local law, nor shall any license or authority other than that which is issued or permitted pursuant to this subchapter authorize engaging in the home improvement business." Section 20-397 also exempts any home improvement "where the aggregate contract price for all labor materials and other items is less than two hundred dollars," and expressly kills that exemption "where the work is only part of a larger or major operation" or where the job is split into sub-$200 contracts to evade the rule.
NYC - workers' compensation insurance (application is DENIED without it): DCWP states that it "will deny your application if you fail to provide the required documents and information," and workers' compensation proof is one of them. You must submit EITHER "[a]n Insurance Certificate for workers' compensation insurance from a private insurance carrier or the New York State Insurance Fund Office," which "must name the Department of Consumer and Worker Protection as the certificate holder and include the Department's address: 42 Broadway, New York, NY 10004," OR "[a] Certificate of Attestation of Exemption from the New York State Workers' Compensation Board" (form CE-200), listing DCWP under "Business Applying For." DCWP warns that "ACORD Forms are not acceptable proof of New York State workers' compensation coverage," and that you must provide proof of coverage if the business stops qualifying for the exemption. The Workers' Compensation Board states the CE-200 "is completed by entities with no employees and/or out-of-state entities obtaining a contract or license in which all the work is being performed outside of New York State."
NYC - fingerprints and processing fee (IdentoGO, service code 1585BH): DCWP requires that "[a]ll sole proprietors, general partners, corporate officers, principals, directors, members, and all shareholders owning more than 10% of company stock must schedule an appointment with IdentoGO to be fingerprinted." Book at uenroll.identogo.com using Service Code 1585BH, with the digits of your DCWP Application Number as the Agency ID, then "[f]ollow the instructions and pay the required fee(s)." Note this is a per-person requirement covering every principal, whereas only ONE principal need sit the Home Improvement Exam. The statutory basis is NYC Admin Code sec. 20-390(7), which requires fingerprinting for criminal-history records from the state Division of Criminal Justice Services and states that "[t]he applicant shall pay a processing fee as required by the state division of criminal justice services"; that section also requires three current passport-size photographs of each person fingerprinted. DCWP does not publish the fingerprint processing fee amount on the checklist - it is set and collected by IdentoGO/DCJS at booking - so treat it as a real, unpriced cost on top of the license fee, exam fee and bond.
NYC - EPA certification is LEAD (RRP + Lead Abatement), not EPA 608: The EPA certification DCWP asks for is the LEAD-PAINT one, and holding EPA Section 608 (refrigerant) certification does not satisfy it. DCWP requires "[c]opies of EPA Renovation, Repair, and Painting (RRP) certification AND EPA Lead-Based Paint Activities certification (also known as Lead Abatement certification)," including name, EPA certificate number and expiration date; alternatively, submit one of the two plus "a signed Home Improvement Contractor Affirmation indicating that the other EPA certification is not required," or a signed Affirmation that neither is required for the work you perform. NYC Admin Code sec. 20-390(6) codifies this, requiring documentation of certification "as required by subparts E and L of part 745 of title 40 of the code of federal regulations" (Subpart E = Renovation, Repair and Painting; Subpart L = lead-based paint activities/abatement) or a signed affirmation that it is not required. EPA's own rule: "anyone paid to perform work that disturbs paint in housing and child-occupied facilities built before 1978 must be certified in lead-safe work practices. This includes all firms, even sole proprietorships" - which is easily triggered by cutting into walls, ceilings and chases to run ductwork, linesets or flues in New York's pre-1978 housing stock. EPA Section 608 is a separate, federal refrigerant credential (see below) and is not part of the DCWP checklist.
NYC - Home Improvement Exam and $50 exam fee: "A sole proprietor, general partner, corporate officer, principal, director, member, or shareholder owning 10% or more of company stock must schedule an appointment with ExamBuilder to take the Home Improvement Exam," but "[o]nly ONE of the following persons needs to pass" it - confirm with DCWP who will sit it. The exam can be scheduled 24 hours after DCWP processes the completed application, and must be passed within 60 days of appearing in ExamBuilder's system. "The exam consists of 30 questions. You must answer a minimum of 21 questions correctly to pass. The fee is $50. The exam fee is separate from the license fee and is nonrefundable. If you fail the exam twice, you must pay the exam fee again in order to retake the exam."
NYC - $20,000 surety bond OR $200 DCWP Trust Fund enrollment: Either enroll the business in the DCWP Trust Fund - "[t]he fee for joining the Trust Fund is $200" - or submit "a copy of a $20,000 Surety Bond (or Third Party Bond), properly signed," which "must name the Department of Consumer and Worker Protection as the Certificate Holder," together with a bond receipt showing it is paid in full and does not expire before the end of the licensing period. Corporate name, DBA and premises address must match exactly across all documents.
NYC - Sales Tax ID / Certificate of Authority: The DCWP application requires a "Sales Tax Identification Number OR Application Confirmation Number"; DCWP directs applicants to businessexpress.ny.gov "[t]o apply for a Certificate of Authority to collect sales tax." New York's Tax Department states that "[e]very person who sells taxable tangible personal property or taxable services ... must register with the Tax Department through New York Business Express before beginning business," which is what produces the Certificate of Authority and the sales tax ID number.
NYC - Contractual Compliance Agreement, and the other application documents: DCWP requires a signed Contractual Compliance Agreement (downloadable from the checklist), and directs applicants to the Contractual Compliance Checklist and the model Home Improvement Estimate and Final Contract "to make sure your contracts meet the legal requirements." The rest of the application package: the Basic License Application; proof of business address and proof of home address for each individual listed (utility bill, lease/deed, government correspondence, bank statement etc., dated within 90 days where applicable); a Granting Authority to Act Affirmation if someone other than the applicant prepares and submits the application; and the applicable Business Certificate for the entity type (DCWP does not require it up front but "may request this document under section 20-104 of the New York City Administrative Code").
NYC - license fee and term (tiered $25-$125; expires February 28 of an odd year): The HIC license runs 2 years and always expires February 28 in an odd year, so the fee depends on when in the cycle you file: $100 (filed March 1 - August 31 of an odd year, license runs to the next odd-year February 28); $75 (September 1 of an odd year - end of February of an even year); $50 (March 1 - August 31 of an even year); and, filing September 1 of an even year through February 28 of an odd year, either $25 for a license to the soonest odd-year February 28 or $125 for a 30-month license to the next one. Card payments carry "a nonrefundable 2% Convenience Fee." These are DCWP license fees only - the $50 exam fee, the bond or $200 Trust Fund fee, and the IdentoGO fingerprint processing fee are all separate and additional.
NYC - hauling out the old furnace or condenser: BIC trade-waste registration: DCWP's checklist warns: "If you plan to haul or transport waste resulting from your business operations, you must obtain a Class One Self Hauler Registration from the New York City Business Integrity Commission." Read BIC's own scope before assuming which registration applies to a furnace or condenser removal. BIC: "You need a Class 1 Self Hauler Registration if you or your business removes its own waste. This does not include construction and demolition debris" - the Class 1 application fee is $1,000, plus a $400-per-vehicle Trade Waste Hauling Vehicle Registration. Separately, BIC states "You need a Class 2 Registration to remove only waste from building demolition, construction, alteration or excavation." Which registration a given HVAC changeout falls under is a scope question BIC does not answer by trade on these pages; confirm with BIC (212-437-0555) rather than guessing. Alternatively, hire a BIC-licensed private carter - BIC: "If your business does not want to haul its own waste, it must hire a Business Integrity Commission (BIC) licensed private carter."
NYC - DOB has no HVAC license; the fuel/mechanical trades are licensed separately: The NYC Department of Buildings publishes 22 license and registration types - Concrete Safety Manager, Concrete Testing Laboratory, Construction Superintendent, Contractor, Electrician, Elevator, Filing Representative, Gas Work Qualification, General Contractor Registration, High Pressure Boiler Operating Engineer, Hoisting Machine Operator, Limited Hoisting Machine Operator, Lift Director, Oil Burner Equipment Installer, Plumbing and Fire Suppression (Master and Journeyman), Professional/Inter-Agency Identification Card, Rigger, Safety Registration, Sign Hanger, Site Safety Professional, Special Inspection Agency and Welder. There is no HVAC, air conditioning, refrigeration or mechanical-contractor license among them. Depending on the equipment and fuel involved, the mechanical side of a job may still require a DOB Oil Burner Equipment Installer license, a Gas Work Qualification, a High Pressure Boiler Operating Engineer license, or a licensed Master Plumber - and these are additional to, not substitutes for, the DCWP home-improvement license (NYC Admin Code sec. 20-387(b)).
Nassau County - Home Improvement Business License (Dept. of Consumer Affairs): Nassau County's Department of Consumer Affairs (DCA) names HVAC directly. Its definition of "Home Improvement" covers work on "a private residence or dwelling place for not more than three families" and "shall include, but not be limited to, the installation, construction, replacement, or improvement of ... central heating or air conditioning systems," and its "Who Must Be Licensed?" list of covered trades opens with "air conditioning & heating systems." Fees (Nassau DCA fee schedule, "EFFECTIVE JANUARY 1, 2020 AS PER LOCAL LAW"): new Home Improvement Business License $650, plus a one-time $50 restitution fund fee; renewal of all business licenses $650; late renewal fee $110; duplicate home improvement license $60.
Westchester County - Home Improvement Contractor license (Dept. of Consumer PROTECTION): Westchester's agency is the Department of Consumer PROTECTION, not consumer affairs: "Westchester law requires that home improvement contractors have a county license. A list of licensed contractors is maintained by the Department of Consumer Protection." The county's licensing law (Westchester County Code ch. 863, art. XVI) defines "home improvement" as work "made to, in or upon a private residence, townhouse, condominium, apartment, or dwelling place of not more than three units," and its enumerated list of covered work includes "HVAC" by name (sec. 863.312, item r). The article's exclusions (sec. 863.324(4)) cover plumbing work, electrical work, architectural services, and "[w]ork or services performed by a person within the scope of an occupation, craft or profession in which such person has met standards of competency or experience established by state law" - HVAC is not among the exclusions. Questions: Consumer Protection, (914) 995-2155.
Suffolk County - Home Improvement license (Dept. of Consumer Affairs): Suffolk County Consumer Affairs issues a Home Improvement license - "[o]ver 50% of the licenses issued or renewed each year are home improvement licenses" - and separately licenses Master Electricians, Master Plumbers, Restricted Plumbers and Restricted Electrical, but publishes no HVAC or refrigeration trade license. Note the limit of what Suffolk itself publishes: its list of home-improvement work ("a very broad term that includes, but is not limited to" arborists, awnings, basements, cabinet makers, carpentry, dormers, driveways, excavating, extensions, exterminating, flooring, garages, insulation, kitchens, landscapers, masonry, painting, railings, roofing, siding, swimming pools, tile installers, tree services, waterproofing, weatherproofing) does NOT name HVAC, heating or air conditioning, and the list is expressly non-exhaustive. Suffolk's published pages do not settle whether an HVAC changeout requires the home improvement license - call Consumer Affairs at (631) 853-4600 and confirm before bidding.
FEDERAL (everywhere in NY) - EPA Section 608 refrigerant certification: Separate from every New York license: under the Clean Air Act and 40 CFR part 82, subpart F, technicians who maintain, service, repair or dispose of equipment that could release refrigerant must hold EPA Section 608 certification. This is a FEDERAL credential, held by the individual technician, and it is neither issued by nor accepted in place of any New York State or local license. It is not the EPA certification DCWP asks for on the HIC checklist (that one is lead: RRP + Lead Abatement).

Legal basis

New York does not license HVAC technicians at the state level.

New York State does not license HVAC. There is no statewide HVAC, air conditioning, refrigeration, heating or mechanical-contractor license, no state board, no state exam and no state fee schedule - and the state has two occupational-licensing agencies, not one, so the negative has to be proved against both. The Department of State’s Division of Licensing Services (DLS) says it “oversees the licensure, registration, and regulation of 35 occupations throughout the state” and names them all: beauty enhancement (cosmetology, nail specialty, waxing, natural hair styling, esthetics, barbering, appearance enhancement); real estate (salespersons and brokers, appraisers, apartment information vendors, home inspectors, manufactured housing); security and secured services (security guards, armored car, private investigators, bail enforcement, watch/guard/patrol agencies, security or fire alarm installers, document destruction, coin processors); and a miscellaneous group (notary, athlete agent, pet cemetery and crematorium, telemarketer, central dispatch, ticket reseller, hearing aid dispenser, bedding manufacturer, durable juvenile product manufacturer, automobile broker, health clubs). The State Education Department’s Office of the Professions - the agency that licenses New York’s professions under Title VIII of the Education Law - publishes a “New York State Licensed Professions” index of 36 professions running from acupuncture to veterinary medicine. HVAC, air conditioning, refrigeration, heating and mechanical contracting appear on NEITHER list. (A caution about the evidence: the DOS page at dos.ny.gov/licensing-services is a landing page carrying a “Miscellaneous - Access all other DOS licensing services” catch-all, so it cannot by itself prove a negative; the Division of Licensing Services page, which enumerates the 35 occupations, can.)

Because there is no state credential, HVAC is licensed below the state - and the positive proof of that runs the other way, from the local codes that expressly claim the work. New York City has no single “HVAC license”: the Department of Buildings publishes 22 license and registration types (Electrician, Oil Burner Equipment Installer, Gas Work Qualification, High Pressure Boiler Operating Engineer, Plumbing and Fire Suppression, General Contractor Registration, Welder and others) and NOT ONE of them is an HVAC, air conditioning, refrigeration or mechanical-contractor license. What NYC does instead is license the work as home improvement: NYC Administrative Code sec. 20-386(2) states that “[w]ithout regard to the extent of affixation, ‘home improvement’ shall also include the installation of central heating or air conditioning systems,” and sec. 20-387(a) makes it unlawful to “solicit, canvass, sell, perform or obtain a home improvement contract as a contractor from an owner without a license therefor.” That license is the Department of Consumer and Worker Protection (DCWP) Home Improvement Contractor license, and it is held by the contracting business, not by the technician - sec. 20-390(3) requires the application to be “filed only by the actual owner of a business,” and sec. 20-397(1) exempts “[a]n individual who performs labor or services for a contractor for wages or salary.” An employed HVAC technician in NYC needs no DCWP license of their own.

There IS a licensed-trade exception, and it is narrow. NYC Admin Code sec. 20-397 (“Exceptions”) says “[n]o contractor’s license shall be required” of “[a] plumber, electrician, architect, professional engineer, or any other such person who is required by state or city law to attain standards of competency or experience as a prerequisite to engaging in such craft or profession … and who is acting exclusively within the scope of the craft, profession or business for which he or she is currently licensed pursuant to such other law.” It is a category, not a named list of DOB licenses, and it survives only while the holder acts EXCLUSIVELY within that other license’s scope. It does not turn a trade license into home-improvement authority - sec. 20-387(b) is explicit that a HIC license does not authorize work “reserved to qualified licensees under separate provisions of state or local law, nor shall any license or authority other than that which is issued or permitted pursuant to this subchapter authorize engaging in the home improvement business.” The two regimes stack. Section 20-397 also exempts any home improvement “where the aggregate contract price for all labor materials and other items is less than two hundred dollars,” but not where the work “is only part of a larger or major operation” or is split into sub-$200 contracts to evade the rule.

The DCWP application is where the real cost and the real traps sit, and two of them are routinely missed. DCWP “will deny your application if you fail to provide the required documents and information,” and that list includes WORKERS’ COMPENSATION INSURANCE - an Insurance Certificate from a private carrier or the New York State Insurance Fund that “must name the Department of Consumer and Worker Protection as the certificate holder” at 42 Broadway, New York, NY 10004, or a Certificate of Attestation of Exemption (CE-200) from the NYS Workers’ Compensation Board (ACORD forms are expressly not accepted). It also includes FINGERPRINTS AND A PROCESSING FEE: “[a]ll sole proprietors, general partners, corporate officers, principals, directors, members, and all shareholders owning more than 10% of company stock must schedule an appointment with IdentoGO to be fingerprinted” - at uenroll.identogo.com, Service Code 1585BH, paying the fee IdentoGO/DCJS charges (NYC Admin Code sec. 20-390(7)). Note the asymmetry: every principal gets printed, but only ONE principal has to pass the exam. And the EPA certification DCWP wants is the LEAD one, not the refrigerant one: “EPA Renovation, Repair, and Painting (RRP) certification AND EPA Lead-Based Paint Activities certification (also known as Lead Abatement certification)” - or a signed Affirmation that one or both are not required for your work (codified at sec. 20-390(6), which cites 40 CFR part 745 subparts E and L). Holding EPA Section 608 does not tick that box. Beyond those: a $20,000 surety bond or $200 DCWP Trust Fund enrollment; the Home Improvement Exam ($50, 30 questions, 21 to pass); a Sales Tax Identification Number / Certificate of Authority; a signed Contractual Compliance Agreement; proof of business and home address; and a tiered license fee of $25, $50, $75, $100 or $125 depending on where in the two-year cycle you file (all HIC licenses expire February 28 of an odd year). If you plan to haul away the equipment you rip out, DCWP points you to a Business Integrity Commission trade-waste registration - BIC’s Class 1 Self Hauler Registration ($1,000, plus $400 per vehicle) covers a business hauling “its own waste” but expressly “does not include construction and demolition debris,” for which BIC has a separate Class 2 Registration; confirm with BIC which one your changeout falls under rather than guessing.

Outside New York City, the credential is a COUNTY home-improvement license - but the counties differ, including in what their agency is called and in whether they name HVAC at all, so check the county you will actually work in rather than assuming. Three are verified here. NASSAU: the Department of Consumer Affairs licenses home improvement, and its definition expressly covers “central heating or air conditioning systems” while its list of covered trades opens with “air conditioning & heating systems”; a new Home Improvement Business License is $650 plus a one-time $50 restitution fund fee, renewals $650. WESTCHESTER: the agency is the Department of Consumer PROTECTION (not consumer affairs), a county license is required, and the county code’s list of covered work names “HVAC” outright while exempting plumbing work, electrical work and architectural services. SUFFOLK: the Department of Consumer Affairs issues a home improvement license and separately licenses master plumbers and master electricians, but publishes no HVAC trade license, and its published list of home-improvement work does not name HVAC or heating/air conditioning (the list is explicitly non-exhaustive) - call (631) 853-4600 and confirm before bidding. Erie (Buffalo), Onondaga (Syracuse) and Monroe (Rochester) were NOT checked for this record; do not assume they follow the downstate pattern.

Finally, and separately from every New York license: EPA Section 608 certification is FEDERAL. Under the Clean Air Act and 40 CFR part 82, subpart F, anyone who maintains, services, repairs or disposes of equipment that could release refrigerant must be Section 608 certified. It applies everywhere in New York, it is held by the individual technician, and it is not a substitute for - or a component of - any city or county home-improvement license.

What it’s called

New York does not license HVAC technicians or contractors at the state level; licensing is handled locally (New York City and other municipalities). A search for a “New York HVAC license” maps to a local license. Separately, the federal EPA Section 608 certification (to handle refrigerants) is a nationwide requirement, not a state or local HVAC license. “HVAC license,” “AC license” and “HVAC certification” are common informal names for the local credential.

Who does NOT need a license — exemptions

New York State licenses no HVAC occupation, so the operative carve-outs are New York City’s - where residential HVAC work is licensed as home improvement under the DCWP Home Improvement Contractor regime. NYC Administrative Code 20-386(2) pulls HVAC in expressly ("[w]ithout regard to the extent of affixation, ‘home improvement’ shall also include the installation of central heating or air conditioning systems"), and 20-397 then lists who needs no HIC license: (1) “[a]n individual who performs labor or services for a contractor for wages or salary” - employed HVAC technicians need no license of their own, only the business does; (2) a plumber, electrician, architect, professional engineer “or any other such person” holding a state- or city-mandated competency credential - including persons licensed under General Business Law article 6-D for security or fire alarm work - while “acting exclusively within the scope” of that other license; (3) retail clerks and clerical employees of a licensed contractor for on-premises transactions; and (5) any home improvement “where the aggregate contract price for all labor materials and other items is less than two hundred dollars,” an exemption that evaporates when the job is part of a larger operation or is split into sub-$200 contracts to evade the rule. The definition of “home improvement” itself also excludes new-building construction, sellers of goods who perform no installation, residences owned or controlled by the state or a municipal subdivision, and standalone painting or decorating (20-386(2)(i)-(iv)). All of this is New York City law only; other New York localities regulate HVAC work, if at all, under their own codes.

Where to get licensed

There is no statewide New York board to call. Identify the city and county where the work will be performed, then go to that locality’s licensing authority.

IN NEW YORK CITY: apply to the Department of Consumer and Worker Protection (DCWP) for a Home Improvement Contractor license (nyc.gov DCWP license checklist - apply online). Budget for ALL of it, not just the license fee: the tiered license fee ($25/$50/$75/$100/$125 depending on where in the two-year, Feb-28-odd-year cycle you file, plus a 2% card convenience fee); the $50 Home Improvement Exam fee (ExamBuilder; 30 questions, 21 to pass; only one principal must pass it); a $20,000 surety bond OR $200 DCWP Trust Fund enrollment; and the IdentoGO fingerprint processing fee - EVERY sole proprietor, general partner, corporate officer, principal, director, member and >10% shareholder must be fingerprinted (uenroll.identogo.com, Service Code 1585BH). Have ready: proof of workers’ compensation insurance naming DCWP as certificate holder at 42 Broadway, New York, NY 10004, or a CE-200 Certificate of Attestation of Exemption from the NYS Workers’ Compensation Board (ACORD forms are NOT accepted); EPA RRP + Lead Abatement certification, or a signed Affirmation that one or both are not required - this is the LEAD certification, and EPA 608 will not satisfy it; a Sales Tax Identification Number / Certificate of Authority (register via New York Business Express); a signed Contractual Compliance Agreement; and proof of business and home address. If you will haul away the furnaces and condensers you remove, ask the Business Integrity Commission (212-437-0555) which trade-waste registration applies - Class 1 Self Hauler ($1,000 + $400/vehicle) covers a business’s own waste but not construction and demolition debris, which falls under BIC’s Class 2 registration. For the fuel and mechanical side of the job, check whether a NYC Department of Buildings credential is also needed (Oil Burner Equipment Installer, Gas Work Qualification, High Pressure Boiler Operating Engineer, or a licensed Master Plumber) - these stack with the DCWP license and do not replace it (NYC Admin Code sec. 20-387(b)). One narrow exception exists (sec. 20-397): a person licensed under another state or city competency-based trade law needs no HIC license WHILE ACTING EXCLUSIVELY WITHIN THAT LICENSE’S SCOPE - and separately, jobs under $200 in aggregate contract price are exempt unless they are part of a larger operation.

IN THE SUBURBS: apply to the county. Nassau County - Department of Consumer Affairs, Home Improvement Business License ($650 new, $650 renewal, one-time $50 restitution fund fee); its rules name central heating and air conditioning explicitly. Westchester County - Department of Consumer PROTECTION, (914) 995-2155; a county home improvement contractor license is required and the county code lists HVAC by name. Suffolk County - Department of Consumer Affairs, (631) 853-4600; it issues a home improvement license but its published list of covered work does not name HVAC, so call and confirm whether your scope requires it. For Erie (Buffalo), Onondaga (Syracuse), Monroe (Rochester) and every other county and city not listed here, contact that locality directly - this record does not cover them and the downstate pattern should not be assumed.

EVERYWHERE IN NEW YORK: if your work involves refrigerants, get EPA Section 608 certification. That is a FEDERAL credential (40 CFR part 82, subpart F), held by the individual technician, and it is separate from every New York license above.

Frequently asked questions

Does New York State require an HVAC license?

No. New York issues no statewide HVAC, air conditioning, refrigeration or mechanical-contractor license, and the state has two licensing agencies, neither of which lists the trade. The Department of State’s Division of Licensing Services regulates 35 named occupations (beauty enhancement, real estate, security services, and a miscellaneous group), and the State Education Department’s Office of the Professions licenses 36 professions under Title VIII of the Education Law. HVAC is on neither list. The credential you need is issued by the city or county where you work.

Do you need a license to do HVAC work in New York City?

Yes, but not an ‘HVAC license’ - NYC has none. Residential HVAC is licensed as HOME IMPROVEMENT: NYC Administrative Code sec. 20-386(2) folds “the installation of central heating or air conditioning systems” into the definition of home improvement, so the contractor needs a Home Improvement Contractor license from the Department of Consumer and Worker Protection (DCWP). The license belongs to the business, not the technician - an employee working for wages or salary needs no license of their own (sec. 20-397(1)). Depending on the fuel and equipment, a NYC Department of Buildings credential (Oil Burner Equipment Installer, Gas Work Qualification, High Pressure Boiler Operating Engineer, or a licensed Master Plumber) may also be required on top.

Is there a DOB licensed-trade exemption from the NYC Home Improvement Contractor license?

Yes - and it is narrower than it sounds. NYC Admin Code sec. 20-397 says “[n]o contractor’s license shall be required” of “[a] plumber, electrician, architect, professional engineer, or any other such person who is required by state or city law to attain standards of competency or experience as a prerequisite to engaging in such craft or profession … and who is acting exclusively within the scope of the craft, profession or business for which he or she is currently licensed pursuant to such other law.” It is written as a category, not as a list of named DOB licenses, and it applies only while the holder works EXCLUSIVELY inside that other license’s scope. It does not make a trade license a substitute for the HIC license: sec. 20-387(b) provides that no “license or authority other than that which is issued or permitted pursuant to this subchapter” authorizes “engaging in the home improvement business.” There is also a small-job exception - any home improvement under $200 in aggregate contract price, unless the work is part of a larger operation or is split into sub-$200 contracts to evade the rule.

What does the NYC Home Improvement Contractor license actually cost, and what gets an application denied?

DCWP says it “will deny your application if you fail to provide the required documents and information.” Two costs are routinely forgotten. First, WORKERS’ COMPENSATION INSURANCE: you must submit an Insurance Certificate that names DCWP as the certificate holder (42 Broadway, New York, NY 10004), or a Certificate of Attestation of Exemption (CE-200) from the NYS Workers’ Compensation Board - ACORD forms are expressly not accepted. Second, FINGERPRINTS AND A PROCESSING FEE: every sole proprietor, general partner, corporate officer, principal, director, member and shareholder owning more than 10% of the stock must book with IdentoGO (uenroll.identogo.com) using Service Code 1585BH and pay the fee at booking. On top of those: the $50 Home Improvement Exam fee (30 questions, 21 to pass; only one principal must sit it), a $20,000 surety bond or $200 DCWP Trust Fund enrollment, and a license fee of $25, $50, $75, $100 or $125 depending on where in the two-year cycle you file (all licenses expire February 28 of an odd year).

Does EPA 608 certification satisfy the EPA requirement on the NYC home improvement application?

No - and this is the single easiest way to get a DCWP application rejected. The EPA certification DCWP asks for is the LEAD one: “EPA Renovation, Repair, and Painting (RRP) certification AND EPA Lead-Based Paint Activities certification (also known as Lead Abatement certification),” or a signed Home Improvement Contractor Affirmation that one or both are not required for your work. This is codified at NYC Admin Code sec. 20-390(6), which cites 40 CFR part 745 subparts E and L. EPA Section 608 is a completely different, FEDERAL credential (40 CFR part 82, subpart F) for handling refrigerants - required everywhere in New York if you could release refrigerant, held by the individual technician, and irrelevant to the DCWP lead requirement. You may well need both.

How do HVAC contractors get licensed in the New York suburbs?

Through the county - but check the specific county, because they differ and even the agency’s name differs. In NASSAU County the Department of Consumer Affairs issues a Home Improvement Business License ($650 new, $650 renewal, plus a one-time $50 restitution fund fee), and its rules name “central heating or air conditioning systems” explicitly. In WESTCHESTER the agency is the Department of Consumer PROTECTION (not consumer affairs); a county home improvement license is required, and the county code lists “HVAC” by name among covered work. In SUFFOLK the Department of Consumer Affairs issues a home improvement license and separately licenses master plumbers and master electricians, but its published list of home-improvement work does not name HVAC - call (631) 853-4600 and confirm your scope before bidding. Erie (Buffalo), Onondaga (Syracuse) and Monroe (Rochester) are not covered by this record; contact those localities directly.

Do I need a permit to haul away the old furnace or condenser in NYC?

DCWP’s checklist says that “[i]f you plan to haul or transport waste resulting from your business operations, you must obtain a Class One Self Hauler Registration from the New York City Business Integrity Commission.” Check BIC’s scope before you assume which registration applies: BIC’s Class 1 Self Hauler Registration ($1,000 application fee, plus $400 per vehicle) covers a business that “removes its own waste” but expressly “does not include construction and demolition debris,” and BIC has a separate Class 2 Registration for “waste from building demolition, construction, alteration or excavation.” BIC’s pages do not resolve by trade which one a furnace changeout falls under - call BIC at 212-437-0555. The alternative is to hire a BIC-licensed private carter.

Is there one place to get a New York HVAC license?

No. There is no statewide board, exam or fee schedule, so there is nothing to apply for at the state level. Identify the city and county where the work will be performed and apply to that locality (NYC DCWP for home improvement, plus NYC DOB for the fuel/mechanical trades; or the relevant county’s consumer affairs / consumer protection office). Separately, obtain federal EPA Section 608 certification if you handle refrigerants.
