CSI has been in business for more than twenty years and our roots go back nearly a century. But management has never taken the future for granted. Generations of expertise give us a strong foundation from which to venture into new technologies, among them green building HVAC systems like variable refrigerant flow (VRF).

Total owner involvement and direct access for customers to our staff ensure sound technical advice and fast decisions.

We balance our business between the light commercial and residential markets. On any given day, we might be involved in an exotic application like radiant heat systems for helicopter pads or retrofitting a home with the right energy-efficient heating and cooling system.

Among the niches where we maintain a leadership position are heat recovery systems, including Energy Recovery Ventilators (ERV), ductless-split systems, radiant heating, variable refrigerant flow systems (VRF) and geothermal applications.

We have become a trusted resource for contractors and engineers in assisting with engineering, application, service and technical issues.  We offer CAD (computer-aided design) drawings, job-site project evaluations and on-site technical support in addition to selling major brands of heating and cooling systems. We also host regular training seminars on the latest HVAC technologies.

We're also the Western Pennsylvania representative for Florida Heat Pump, the manufacturer of Geothermal and Closed Loop heat Pumps as well as Renew Aire air-to-air Heat Exchange Ventilators.
