New York State does not issue a general HVAC contractor license. In New York City, the Department of Consumer and Worker Protection lists central air or heating installation among the residential jobs that need a Home Improvement Contractor license, which is required for work totaling more than $200.
Statewide, residential HVAC installations fall under General Business Law §771, which requires a written, signed contract with the contractor’s contact details, estimated dates, the equipment by make or model and the agreed price.
Any technician who services or disposes of refrigerant equipment must hold EPA Section 608 certification. That certification belongs to the individual, so a homeowner can ask which certified technician did the work.
Our view: a review that says an NYC company installed central air without a license is checkable against the city record. When the record contradicts the claim, that is a factual dispute we document for the platform.
