The vast majority of self-contained condenser coils now in service are not cleaned under existing preventative maintenance protocols: they are allowed to run dirty. One refrigeration expert recently stated, “Eighty percent of operators do nothing, no maintenance, ever. Maybe 20 percent do some, but not enough”. Source: Refrigeration Magazine December, 2015. Coils need cleaning at least quarterly for: (a) reduced electrical usage; (b) reduced service calls; and (c) prolonged equipment life. Dirty coils are the main reason for service calls. With routine quarterly maintenance, operators have virtually no breakdowns. Sources: Food Service Technology Center (FSTC), San Ramon, CA and Refrigeration Magazine December, 2015. Exemplary yearly savings per unit if the coils are clean: Electric energy savings of from $220 to $625, depending on the type and size of unit (or from about 46 percent to 50 percent electric savings). Source: Cool Savings Project – FSTC and the City of San Francisco. Compressed air is needed to quickly and effectively remove deeply deposited dirt/debris inside the coil’s structure.
