Our History

PCSOC was established in 2002 as a privately-owned, independent company from the sale of the local Invensys Building Systems branch office. The buyout established PCSOC as the sole manufacturer’s representative of the Invensys product line in the Chicagoland area. This product line included legacy Network 8000 and DMS Systems manufactured by Barber-Colman, Robertshaw, and Siebe Environmental Controls. As of 2009, Invensys became an integral part of the Schneider Electric family of building automation and temperature control solutions.

Throughout these product mergers and acquisitions, PCSOC has been steadfast in maintaining exceptional client service, safety, and quality while experiencing sustainable growth in our business units.
