Air Conditioning System Crucial to guests' comfort, hotel air conditioning systems involve multiple pieces of equipment such as centrifugal chillers, compressors, pumps, condensers, cooling towers and a variety of air handling fans, blowers and other equipment. In most cases breakdowns are the result of electrical breakdown of motors or mechanical breakdown of compressors. The compressor alone can be worth $20,000 or more. Lack of air conditioning can force hotel owners to rent temporary equipment or face loss of guests and income. © 2004 The Hartford Steam Boiler Insurance and Inspection Company.     All rights reserved.
