Refrigeration Service Company

Family-owned commercial refrigeration specialist in South Williamsport, in business since 1972 and owned and operated by the Dieffenbach family since 1982, currently under John H. Dieffenbach III. Handles design, layout, installation, service, and maintenance of commercial, supermarket, and industrial refrigeration plus HVAC sales and service across North Central Pennsylvania. Equipment covered includes ice machines, walk-in and reach-in coolers and freezers, beer dispensing equipment, food display cases, and sub-tables. Clients include supermarkets, restaurants, taverns and bars, colleges and schools, convenience stores, manufacturing facilities, refrigerated warehouses, and meat packing plants. Their Wholesale Chef division is the area dealer for Manitowoc Foodservice, Champion dishwashing machines, Star Manufacturing, Arctic Air, and Viking. On call 24 hours a day, seven days a week, with preventive maintenance contracts available. Two things worth knowing: they state plainly that they do not service residential customers, and their email is for office-hours inquiries only, so after-hours emergencies must go by phone. We called after hours: the line works and routes to a voicemail for the on-call emergency technician to return, rather than a live answer. Note this is a refrigeration and HVAC specialist rather than a cooking equipment company.
