The Long History Northern Weathermakers, HVAC

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 74 years later, the Carlson Building is still a customer. While we are proud of this fact, we are not surprised. At Northern Weathermakers HVAC, Inc., customer service is the cornerstone of our business.

Today, Northern Weathermakers HVAC, Inc. offers the highest quality sales and service on commercial and Industrial heating, air conditioning and building automation systems in IL. and energy management areas associated with HVAC.
