In 1984, control was passed to Edward Van Hook, the current CEO and owner. Starting out as a centrifugal and absorption chiller service company, we have since expanded. We now service all types and brands of mechanical equipment including most DDC controls. Van Hook Service Co., Inc. now has more than sixty service technicians, each with their company-owned, fully equipped service vehicle. We respond to our customers' needs 24 hours a day, 365 days a year.
