Mechanical Supply Company Inc. started business in 1955 in St. Louis, MO. The company operated two different mid-town locations until 1990.

Our first branch store was opened in 1961 in Springfield, IL. We are currently operating from our third Springfield location at 2785 South 11th Street in a large modern building designed for our type of business.

Our third location was opened in 1972 at 96 Weldon Parkway, Maryland Heights, MO. This was the first HVAC/R West County location in the St. Louis Metro Area. The store size was doubled in 1987 to stock a broader product offering to an expanding customer base.

Our fourth store opened in Fairview Heights, IL in 1989 and was moved to a larger building at our present location 319 Centreville Avenue in Belleville, IL. This store serves a growing Metro East population and features commercial packaged heating and cooling equipment storage.

Our fifth location was opened in 1996 to serve the fast growing Jefferson County and surrounding areas. The store was located at 1304 Commercial Blvd. in Herculaneum, MO. After 10 years of serving Jefferson County, the store was relocated to a larger, better designed building in order to accomomdate the growth of this area. The store is now located at 720 S. Mill St. in Festus, MO.

Our sixth location was opened in 2007. The O'Fallon branch was added to serve an expanding population in the St. Charles county area. This branch is located at 827 W. Terra Lane in O'Fallon, MO.

Mechanical Supply Company headquarters was relocated from St. Louis City to St. Louis County in 1986 to address additional warehouse requirements and better serve the population shift. This also serves as our distribution center replenishing all our branch stores weekly. The address is 919 Horan Drive, Fenton, MO.
