Strong ROI for Kitchen Hood Demand-Control Ventilation

Edgewood College had an energy conservation fund with strict technical and payback criteria.The old kitchen HVAC systems in Predolin Humanities Center and Regina Hall were selected for upgrades.The goals were to save energy, reduce noise levels, decrease grease entrapment, and reduce HVAC equipment wear.

“Remarkable! Very, very happy with the outcome. Your guys were awesome. Documentation was also more than expected. Follow-up service has been exceptional and timely. Thank you!”
