New York HVAC license requirements, reciprocity and contract rules.

This page lists what New York publishes about licensing an HVAC or mechanical contractor and contracting with homeowners: who issues the license, whether one is required statewide, the classes and qualifications, insurance or bond minimums, reciprocity with other states, renewal and continuing education, and the state's home-improvement contract statute if it has one.

It is built for owners of residential HVAC companies, especially those hiring across a state line or opening a second territory. Every entry is a snapshot of what the cited source published on the verification date; it is a research starting point, not legal advice.

New York, field by field.

Contractor licensing authority

No state agency licenses HVAC or home-improvement contractors. The New York Attorney General's Home Improvement fact sheet states "Home improvement contractors must be licensed in New York City, Suffolk, Nassau, Westchester, Putnam, and Rockland counties." and "A contractor must also continue to comply with any local licensing laws." The Department of State Division of Licensing Services page, which says the Division "oversees the licensure, registration, and regulation of 35 occupations throughout the state.", lists no HVAC, heating, mechanical, refrigeration or home improvement contractor occupation.

HVAC license required

Local only — no statewide HVAC or mechanical license; licensing applies where a city or county requires it, including the jurisdictions named by the Attorney General (New York City and Suffolk, Nassau, Westchester, Putnam and Rockland counties). Statewide, General Business Law § 771(1)(a) requires a home-improvement contract to state "The name, address, telephone number and license number, if applicable, of the contractor."

License classes & qualifications

None at state level; classes and qualifications are set by each licensing city or county.

Insurance / bond minimum

No state license bond or liability-insurance minimum. Payment protection under GBL Article 36-A and the Lien Law: a home improvement contractor must deposit payments received before substantial completion into an escrow account at a New York bank or similar institution "within five business days" of receipt and, unless the contract names the depositary, notify the owner in writing of where the funds were deposited "no later than ten business days after the deposit has been made" (Lien Law § 71-a(4)(a)); in lieu of the deposit the contractor may deliver to the owner a surety bond, contract of indemnity or irrevocable letter of credit guaranteeing the return or proper application of the payments "within ten business days after receipt of the payment" (Lien Law § 71-a(4)(b); GBL § 771(1)(e)); withdrawals from escrow may not exceed what the payment schedule allows (Lien Law § 71-a(4)(e)); payments for work billed on an hourly or time basis are outside subdivision 4 (Lien Law § 71-a(4)(f)).

Reciprocity

None published — no state license exists.

Renewal & continuing education

No continuing-education requirement published — no state license exists.

Home-improvement contract rule

General Business Law Article 36-A (§§ 770–776; § 771-b covers roofing contractors). A "home improvement contract" is an agreement between a home improvement contractor and an owner where the aggregate price in one or more contracts "exceeds five hundred dollars." (§ 770(6)); a "home improvement contractor" is one for whom the total cash price of all home improvement contracts with all customers "exceeds one thousand five hundred dollars during any period of twelve consecutive months." (§ 770(5)); "owner" includes a homeowner, co-operative shareholder owner, residential tenant or purchaser of a custom home (§ 770(2)); excluded from "home improvement" is "the sale or installation of appliances, such as stoves, refrigerators, freezers, room air conditioners," dishwashers, clothes washers or dryers designed to be removable without material alteration (§ 770(3)(c)). Every covered contract "shall be evidenced by a writing and shall be signed by all the parties to the contract." (§ 771(1)), "legible, in plain English", with a copy signed by the contractor furnished to the owner before any work is done (§ 771(2)), and must contain: "The name, address, telephone number and license number, if applicable, of the contractor." (a); approximate or estimated start and substantial-completion dates and whether a definite completion date is of the essence (b); a description of the work, the materials and the agreed consideration (c); the mechanic's-lien notice (d); the notice that the contractor "is legally required to deposit all payments received prior to completion" under Lien Law § 71-a(4) and may instead post "a bond, contract of indemnity or irrevocable letter of credit with the owner" (e); any progress-payment schedule — "The amount of any such progress payments shall bear a reasonable relationship to the amount of work to be performed," (f), with hourly or time-basis payments for work already provided excluded (g); the notice that "the owner may cancel the home improvement contract until midnight of the third business day" after signing, except for an owner-initiated bona fide emergency with a separate dated handwritten waiver (h); and, effective April 23, 2022, disclosure of "the existence of a property and/or casualty insurance policy" covering the work with the insurer's telephone number and address (i). § 771-a ("Responsibilities of home improvement contractors") bars a contractor from certain financing-related activities and payments connected with a home improvement contract unless the activity and any compensation are disclosed and every party agrees in writing. Penalties: a contractor who violates the article "shall be subject to a civil penalty not to exceed one hundred dollars." (§ 773(1)); failing to escrow or post the alternative security, or to provide a substantially compliant written contract, carries "the greater of two hundred fifty dollars for each violation" or "five percent of the aggregate contract price", and "in no event shall the total penalty exceed twenty-five hundred dollars for each contract." (§ 773(2)), with a bona fide error defense (§ 773(3)); an owner induced by false or fraudulent written representations may sue for a $500 penalty plus reasonable attorney's fees in addition to damages (§ 772(1)).
