Ongoing preventative maintenance is an important aspect of this retailer's commitment to maintaining healthy refrigeration equipment. On a quarterly or biannual basis, our technicians visit all 9 locations across the Portland metro area. Inspecting and cleaning condenser and evaporator coils, checking all glycol systems and levels to assure proper operations; on sites with cooling towers: cleaning towers, baffles, sump pump heaters, and fan motors, verifying case operations and temperatures, inspecting all electrical, and calibrating temperatures as needed. These are all important tasks to ensure the grocer's equipment is always working properly, and reduces the risk of a sudden system failure.
