Since 1928, we’ve been doing one thing—helping our customers do what’s right for theirs. Allied Air is a Lennox International company. We bring together the collective strengths of six comfort brands—Armstrong Air™, AirEase ® , Concord ® , Ducane™, Allied Commercial™ and MagicPak ® to give distributors and dealers the ultimate source for heating and cooling solutions. From compact residential applications to large commercial projects, Allied Air Enterprises redefines ease-of-business through breadth of product, resources and competencies unparalleled in the market. Our headquarters in Columbia, South Carolina purposely brings together marketing, finance, and sales along with our R&D team, all under one roof. Inside our on-site testing and design labs, our engineers use cutting-edge technology to develop and test new ideas quickly and effectively. With engineering, product management, and our development technicians in close proximity, products can move from concept to reality faster. That centralized product development is complemented by a diverse manufacturing footprint. Our five factories across North America supply broad lines of residential and commercial products. Each builds to the same leading quality standards and provides redundancy and specialization to keep products flowing to you.
