About Us

In 1958, Schreiber Enterprises first opened its doors in Los Angeles with owners JJ Johnson and Bing Schreiber. JJ and Bing ran a ColdSpot refrigerator repair shop and later branched out into building water chillers and distributing kitchen appliances. In 1987, JJ sold the appliance distribution portion and kept the small chiller business, Schreiber Engineering, as a retirement hobby. By 2001, it had grown into a company with $8 million in sales and he sold Schreiber to the Dover Corporation.

Jeff Johnson is the grandson of JJ Johnson; Schreiber Engineering and chillers have been a part of his life. Jeff was a third generation Johnson in the chiller business, working in sales and as engineering manager at Schreiber for 4 years. The majority of his focus was designing systems for the welding, plastics, and medical industries and overseeing all facets of the manufacturing and installation. Jeff, along with his wife Sheri, started Johnson Thermal Systems Inc. in 2004 to offer more custom design and service options to specialty HVAC/R customers.

In addition to chiller design and manufacturing for high profile clients such as GE Healthcare, the technical capabilities and customer-oriented approach practiced by JTS has earned the business of customers like The Trane Company, Vilter Manufacturing, Boumatic, as well as numerous hospitals, imaging centers, power plants and municipalities across the United States.
