Air Conditioning System Who wants to shop in a store that is hot and sticky? Most air conditioning and refrigeration breakdowns are the result of either electrical breakdown of the driving motors, or mechanical parts breaking in the compressor. The compressor alone can be worth thousands of dollars. If refrigerant and/or chill water piping breaks, leaks can damage furnishings and contaminate foodstuffs. © 2004 The Hartford Steam Boiler Insurance and Inspection Company.     All rights reserved.
