Inquiry (采购产品): Vibration from a RTU I have a customer that has a RTU emitting a vibration into the structure of the office building causing a very frustrating noise within the office space. I am looking for a local company that can locate the source of the vibration. Please give me a call to discuss the details. **** Hidden Message ***** Lee Schuster 53051 Company: J. F. Ahern Co.
