Commercial Building Controls Supply specializes in providing new and refurbished components for building automation and tempe ... rature controls systems. The company has been a leader in the industry for over 15 years. We strive to provide you with the parts you need, when you need them at a reasonable cost. Some of the vendor’s items that we carry are Alerton, Siemens, Johnson, Honeywell, Distech, Belimo and many more. Because of the changing technology in the industry, some of the older components have reached the end of their life cycle with certain manufacturers, and that is why we carry a variety of older components that are refurbished for systems that are in need of service with their aging building automation system. We have a local store front in the Chicago area, and also a company website where current stock of parts can be viewed and orders placed easily online with credit card processing available.
