Heating Products

Armstrong Air™ is one of the most recognized and respected names in the heating and cooling industry. It is a name synonymous with product integrity, dedicated service and industry leadership. Armstrong Furnace was founded in 1928 in Columbus, Ohio, by a premier manufacturer of home heating equipment, Lennox Furnace Company. Lennox sold Armstrong Furnace to another outstanding firm in 1957. But in 1988, Lennox International Inc. again acquired ownership of its offspring, now called Allied Air Enterprises Inc.
