The Sheet Metal and Air Conditioning Contractors' National Association (SMACNA; pronounced 'Smack'-'Nah') is an international trade association with more than 4,500 contributing contractor members [1] in 103 chapters [2] throughout the United States, Canada, Australia and Brazil. Its headquarters is in Chantilly, Virginia.


Member profileEdit

SMACNA members perform work in industrial, commercial, institutional and residential markets.

Technical manuals and standardsEdit

The voluntary technical standards and manuals developed by SMACNA Contractors have found worldwide acceptance by the construction and design community, as well as local, national, and 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 indoor air quality and 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.

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