Osterwisch

Osterwisch Company continued to increase its work force and client base. Then in 1982 we began the Heating and Cooling Division which further enhanced the capability to service the client's requirements. By 1992 Osterwisch Company decided to provide Plumbing service as well. Once the Plumbing Division was added the Osterwisch Company was positioned to supply clients with Electrical, HVAC and Plumbing service and installation by placing only one call.
