McCotter Energy Systems began as McCotter & Sons, Inc. founded by Howard S. McCotter and his two sons Thomas & Lawrence. The company began selling coal stoking equipment and has evolved with the industry now providing the most comprehensive line of premium HVAC and commercial boiler room systems in the region.


In 2006, the company moved to its current location near downtown Milwaukee and the name was changed to McCotter Energy Systems, Inc. The facility is home to a complete training facility with operating boilers. The Smart Energy Learning lab is a one of a kind training facility where service technicians can be trained and work hands on with the units in operation.

Delivering Smart Energy and Reliable Efficiency is our mission for each project. The high efficiency red boiler package is the key to delivering savings and the longest product life. McCotter Energy Systems is committed to providing the most efficient systems and comprehensive information in order to find the optimal heating solution.

We provide commercial boiler room equipment and service throughout Wisconsin and the Upper Peninsula of Michigan from three locations; our main office in Metro Milwaukee and two satellite offices in Norway, Michigan and De Pere, Wisconsin. Our service technicians are centrally located to provide quick service throughout Wisconsin and the U.P.

Our approach to the application of HVAC and boiler room equipment is straightforward. We believe in selecting equipment that is safe, efficient and will provide the longest operational life for the end user.
