Proco Refrigeration in Chula Vista's Rolling Hills district has specialized in commercial refrigeration and ice-machine service across San Diego County since 2010, operating from its base near MacKenzie Creek Road in the 91914 zip code. Walk-in cooler compressor replacements and reach-in freezer thermostat recalibrations are standard calls, and food-service clients that also contract commercial janitorial teams such as Wepa Commercial Cleaning LLC can keep health-department compliance on parallel tracks. The company services all major commercial brands including True, Turbo Air, Hoshizaki, and Manitowoc ice machines. Restaurant and grocery operators in the Otay Ranch Town Center area who schedule quarterly refrigeration maintenance often pair those visits with pest-management inspections from Nixtermite Inc. to satisfy San Diego County Department of Environmental Health requirements. Highest-tier service calls involve walk-in freezer evaporator coil replacements and R-404A refrigerant recovery performed under EPA Section 608 certification standards.
