Armstrong was one of the first companies in the heating and air conditioning industry to attain ISO 9001 certification. ISO (International Standards Organization) 9001 is a world quality system standard developed to consolidate many existing standards. It goes well beyond any means previously used to assure quality processes and procedures are in place. The certification process involves meticulous examination of Armstrong's product design and development, production, installation and service. ISO 9001 offers a world of assurance to Armstrong customers, dealers and distributors.
