HVAC sheet metal contractors contract with clients to install prefabricated sheet metal ducts used for heating, air conditioning or other purposes.
Typically, only contractors require licenses, not sheet metal workers who work for them. In some states, licensing requirements differ based on the setting. Those with a residential license may work only on residential properties, while those with a commercial license may work on commercial properties. Other states require the same license regardless of the setting, and this report records that license in both settings. Many states have contract minimums before the contractor’s license applies. See Appendix B for details.
