American Combustion Service, Inc. & ACSI Mechanical was founded by Frank M. Lacny in December 1984. The Company has always been based in the southwest suburb of beautiful Mokena, Illinois. In 2009, the company moved to its current location at 19325 S. Schoolhouse Road, Mokena, Illinois. The spacious building is home to corporate offices, stock room and shop for any “in house” fabrication and repairs.
Located off Interstate 80 and Route 45 makes it convenient to travel to service clients up into Wisconsin, Iowa, Indiana and southern Illinois. We have provided services for customers as far east as New Jersey and as far away as Mexico and Alaska.
The consulting and specialized service capabilities for working on any type of fuel burner and/or fuel, has earned American Combustion Service, Inc. a reputation as “burner specialists” – second to none in the area!
Over the years, the Company has consulted and assisted many other contractors in the Chicago and Chicago metropolitan area with burner start-up work, unusual boiler room problem-solving situations, or just some basic back-up service support.
