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.
License required by 37 states
5th most burdensome licensing requirements
16th most widely and onerously licensed occupation
Thirty-seven states license HVAC sheet metal contractors working on commercial properties. Twenty-eight states require between two and six years of experience working under a licensed contractor. Mississippi requires completion of three contracted jobs. Seven states require no education or experience. On average, states require over three years (1,215 days) of education and experience, $394 in fees ($1,078 in Nevada), and about two exams. These high barriers give commercial HVAC sheet metal contractors the fifth most burdensome requirements of the 102 occupations studied.
