Display cases have to hold temperature while being open to the room, which makes them the least forgiving refrigeration in any store. JRC repairs display cases across Needles, CA for groceries, delis, bakeries, butchers and florists.
Open air merchandisers depend on an air curtain, and anything that disturbs it costs you temperature: stock loaded above the load line, a blocked return air grille, a failed evaporator fan, or a store door creating a draught across the case. We check the air curtain before we touch the refrigeration, because a case that has been called faulty for weeks is often just being overloaded. Anti sweat heaters, night curtains and controls all get checked too.
