-- Louis J. Mueller, Sr. began the manufacture of furnaces in 1857 in a small hardware and tin smith shop. By the 1880?s he had developed the first patterns for warm air units, and in 1890, L.J. Mueller Furnace Company was producing steam and hot water boilers. In 1954 the L.J. Mueller Furnace Company merged with Worthington Corporation to become Mueller Climatrol Division of Worthington Corporation and eventually was sold to Fedders.
