About

The Kroeschell Brothers Company began as boiler manufacturers and piping contractors, producing boilers, tanks, stacks and steam separators, as well as designing and installing new systems. While Kroeschell has its roots in boiler manufacturing, an innovation was about to enter the American scene, cooling, and the brothers were destined to be at its forefront.

The Kroeschell Brothers were among the first to embrace cooling technology and by the close of the 19th century, Kroeschell had formed the Kroeschell Brothers Ice Machine Company, and became the first American company to design, manufacture and install CO2 refrigeration equipment up to 250 tons in capacity.

In 1906, Kroeschell pushed the envelope, designing, building and installing an air-cooling system in the Congress Hotel in Chicago, widely recognized as the first air-conditioning system in America. The success of this project and many others led to interest from outside companies. In 1922, Kroeschell merged with the Brunswick Refrigerating Company to form the Brunswick-Kroeschell Company. The combined company was capable of manufacturing carbon dioxide and ammonia equipment for land-based and marine applications.

Eight years later, at the onset of the Wall Street Crash, a three-way merger followed, and Brunswick-Kroeschell joined with both the Carrier Engineering Company and the York Heating and Ventilating Company to form the world-famous Carrier Corporation. However, in 1932, four executives — including Robert and Paul Kroeschell — resigned from Carrier to form the Kroeschell Engineering Company, and a new era began.

Firmly rooted in the city where everything began, the company flourished. In 1934, Kroeschell landed the coveted contract to cool Chicago’s famous Tribune Tower—one of the crown jewels of Chicago architecture. Using a 600-ton chiller that supplied nearly 400 Westinghouse space air conditioners on 32-floors, Kroeschell quickly completed a job described by Westinghouse as “one of the largest unit air conditioning installations in the world.”

From that point forward, Kroeschell continued to expand its operations, providing new services to its swelling client base that comprised some of the best-known institutions and the world’s most respected brands including Abbott Laboratories, the Field Museum of Natural History, Pfizer, University of Chicago Hospitals, Northwestern University, Caterpillar, Ernst & Young, Zurich/Scudder Investments and the Wrigley Company.

In 1959, Kroeschell entered the HVAC service business, founding Kroeschell Engineering Service, Inc. and creating one of the largest service companies in the country. Nine years later, Kroeschell Operations, Inc. was added, providing industrial systems and plant operations support to major manufacturers and government entities.

As the economy went into overdrive in the 1980s, so did Kroeschell, adding even more capabilities. In 1982, Kroeschell acquired O’Callaghan Brothers, Inc., enabling Kroeschell to design, install and service plumbing systems. In 1985, Kroeschell responded to the increasing demand for power distribution and control systems, forming an electrical power and controls department within Kroeschell Engineering Service.

Kroeschell has grown far beyond its original roots, becoming more than a distinguished leader in heating, ventilation and air conditioning systems. Through its many services, Kroeschell has become a global business partner, enhancing the performance and productivity of our customers. After more than 135 years in business, we remain committed to doing it all one relationship at a time.
