Comprehensive chiller maintenance can extend the life of equipment, improve its reliability, save scarce refrigerant, and reduce energy and other operating costs while buying you time to work out a long-range plan. You’ll need design specifications, equipment manuals and repair history for each component, and a cost history for purchase, repairs and operation. Are some components getting more repairs and costing more than others? Are annual energy costs increasing faster than rate increases? Have recent costs exceeded past costs? Are your costs higher than costs at other similar facilities? Are they higher than averages from your professional association?
