When John and Patti Dieffenbach enter a business, workers immediately feel a chill - but that's a good thing.
The Dieffenbachs run Refrigeration Service Co., selling and installing equipment to keep things cool, such as refrigerators, coolers, ice machines and air conditioning systems.
The business was established in 1972 by John's father, and John was promptly introduced to the business.
"He started going with his dad when he was 8 years old on service calls," Patti commented.
Patti said many people in the area have never heard of the business because it focuses on commercial rather than residential services. Refrigeration Service Co. works with restaurants and bars, supermarkets, school districts and other businesses.
Patti said that Refrigeration Services Co. sets itself apart from the competition by offering unbeatable service.
"We have 24/7 emergency service," she said.
When a restaurant's freezer stops working, a delay in service can result it spoiled food.
The workers at Refrigeration Service Co. understand the time-sensitive nature of their work.
"We try to get someone there as soon as possible," Patti said.
The Dieffenbachs' five employees all have been with the business for several years and are experienced in handling problems, she added.
The business's attention to customer satisfaction has helped propel it to success, prompting a move two-and-a-half years ago from the small office on Louisa Street in Williamsport to its current location on Valley Street in DuBoistown.
"We now have a warehouse out back," Patti said, adding, "We have off-street parking now."
The couple also recently added a Wholesale Chef store to their business, allowing customers to browse commercial kitchen offerings such as fryers, ranges and ice machines.
"We can do the installation and service on the equipment," said Patti, who mans the store and works with walk-in customers, while her husband handles the service end of the business. Kitchen ware also is available for those who like to cook at home: The store offers a variety of pots and pans, glass ware, knives and strainers.
"Anyone can come in the store and buy the small stuff," Patti said.
The store is open from 9 a.m. to 3 p.m. Monday through Friday, with additional hours by appointment. More information about The Wholesale Chef is available at the store's website, www.thewholesalechef.com.
Above all, the Dieffenbachs hope to offer the best possible service to area businesses in need of refrigeration or air conditioning services, Patti said: "We just really cater to the commercial customers and help them out with any issues they might have."
