Who licenses HVAC contractors in Southampton

• Suffolk's restricted license application lists Oil Burner and HVAC categories under Restricted Plumbing, and an Oil and Gas Burner category under Restricted Electrical.
• Anyone who intends to do electrical, plumbing or duct work in Suffolk homes must also apply for the required licenses among Restricted Electrical (HVAC), Restricted Plumbing (HVAC) and Home Improvement, the county's application says.
• Suffolk's home improvement law covers heating and ventilation ductwork but leaves out work in the electrical and plumbing fields.
• Suffolk charges a non-refundable $200.00 application fee for a restricted license.
• Southampton requires its own Home Improvement Contractor's License for home improvement work, and its licensing covers every village except the Village of Westhampton Dunes. A builder of a new home needs no town license for now, but the builder's subcontractors must be licensed.
