The Ferris School of Built Environment houses the architecture, construction technology and management, facilities management, and HVACR programs in the College of Engineering Technology.
While HVACR contractors might not be charging a typical visit fee, many of them charge fees when a certain amount of work is done by the tech. Whether or not the customer is okay with that, all depends on the person.
