Mechanical and control systems are becoming increasingly more sophisticated. As a matter of fact, the rate of change technologically is increasing. Mechanical systems changes include refrigerants, motor designs, variable speed drives, magnetic bearings, etc. Control systems changes include advanced PC/server applications, impact of web and web enabled devices. Combined with lack of training the result is………… Products introduced with no one able to install or service them? i.e. 750 page server software installation instructions? Service both NEW and OLD challenges

So, how does this impact our classrooms and what can we do about it? Programs, technology, equipment quickly go out of date. Instructors easily caught behind an increasingly steep technological curve. Introduction of basic Information Technology (IT) training into HVAC programs, especially Controls training classes. Equipment and computer updates, 3 year cycles at most. Materials, books, training aids, etc. up to date Big Task!
