SMACNA's mission is to provide products, services, and representation to enhance members' businesses, markets, and profitability. Located in headquarters outside Washington, D.C., the Sheet Metal and Air Conditioning Contractors' National Association (SMACNA), an international association of union contractors, has 1,834 members in 103 chapters throughout the United States, Canada, Australia and Brazil.

SMACNA members perform work in industrial, commercial, institutional and residential markets. They specialize in heating, ventilating and air conditioning; architectural sheet metal; industrial sheet metal; kitchen equipment; specialty stainless steel work; manufacturing; siding and decking; testing and balancing; service; and energy management and maintenance.

The voluntary technical standards and manuals developed by SMACNA Contractors have found worldwide acceptance by the construction community, as well as foreign government agencies. ANSI, the American National Standards Institute, has accredited SMACNA as a standards-setting organization. SMACNA does not seek to enforce its standards or provide accreditation for compliance. SMACNA standards and manuals address all facets of the sheet metal industry, from duct construction and installation to air pollution control, from energy recovery to roofing. SMACNA's Technical Resources Department fields several thousand technical questions annually from architects, engineers, manufacturers and government personnel. More than 17,000 orders for SMACNA technical manuals are processed and shipped each year from SMACNA national headquarters. This translates into sales of more than 50,000 technical manuals, generating approximately $1 million in income for the association.

The association offers contractors professional assistance in labor relations, legislative assistance, research and technical standards development, safety, marketing, business management and industry issues.
