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 new 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.
