Customer Service and Technical Support

"We focus on how the way we do business translates into added values for our customers. Thus, we customize systems in a turnaround time of 48-72 hours, taking extra precautions to 'burn-in' and test all component parts properly."

Our technical support staff includes networking and Internet experts who hold weekly training meetings with the sales staff to share information about troubleshooting questions and service solutions. Our technical staff continuously works to obtain advanced certifications from major industry manufacturers and to stay abreast of the latest product upgrades and developments.

When you buy a system from Chang & Associates, every component is backed by our no-hassle RMA guarantee.

Customers praise our unique barcoding system because it saves them time in case a return is needed. CSI replaces equipment on the same day if equipment is in stock. Toll-free technical support and service are promptly handled by highly qualified in-house systems engineers and all products carry a one-year replacement warranty through CSI, in addition to the manufacturer's warranty. Optional on-site warranties are also available.
