On February 1, 1949, William L. Hochschild, Jr. founded Northern Refrigeration and Engineering Company. A mechanical engineering graduate of the University of Illinois, Hochschild had previously worked for Ilg Electric Ventilation Company, now a division of Carrier/United Technologies. Our first client was the Carlson Building in Evanston. Today, more than 66 years later, the Carlson Building is still a customer. While we are proud of this fact, we are not surprised. At Northern Weathermakers HVAC, customer service is the cornerstone of our business. Our customers know that they can purchase the finest quality heating and air conditioning equipment and have it installed and serviced by the best in the industry.Today, Northern Weathermakers HVAC offers first-class sales and service on commercial and Industrial heating, air conditioning and building automation systems.
