The two corporations that I manage entered into new contracts with CES approximately two years ago. Their cost for service was in line with others and they offered an energy audit of the building systems. After the contracts began, we quickly determined that CES was attentive and very professional in their dealings with staff and Management. The Energy audits produced areas that the corporations could save on utility costs. Variable speed drives were installed on air handling units and cooling towers. Not only did we see savings but CES assisted in obtaining incentives for work completed. I am pleased to offer recommendations for CES as they have not only performed their work but did so with the best interest of the corporation in mind at all times.
