History
Lennox traces its roots back to 1895, when Dave Lennox designed the first riveted-steel furnace in his machine shop in Marshalltown, Iowa. By the early 1900s, the manufacture of these furnaces—a vast improvement over the cast-iron furnaces of the time—had grown into a significant business and was diverting Dave from his passion for inventing. At this time, a group of investors led by D. W. Norris bought the furnace business and, over the years, ownership of the company was passed on to succeeding generations of the Norris family. In 1999, the company completed the initial public offering of its common stock.
Though the company is now based in Texas, it retains a strong presence in Iowa, with 996,000-sq. -ft. factory in Marshalltown and a 250,000-sq. -ft. distribution center in Des Moines.
