Do HVAC contractors need a license in New York City?
New York City has no general HVAC license. Heating, cooling and ventilation work that needs a permit is filed with the Department of Buildings as mechanical-systems work by a DOB-registered contractor. Oil burner installs need a DOB Oil Burner Equipment Installer license, gas piping needs a Licensed Master Plumber, and anyone handling refrigerant needs federal EPA Section 608 certification.
How can you check the license yourself?
Ask whether the job needs a DOB permit, who will file it, and for the technician's EPA 608 card. Every firm we list filed DOB mechanical-systems permits in the last two years.
