To better serve customers across various regions and gain a deeper understanding of product usage, Hope Deepblue’s After-Sales Service Department has actively responded to maintenance needs while also conducting proactive follow-up visits for both in-warranty and out-of-warranty users. These efforts aim to identify user challenges, provide timely solutions, and lay a solid foundation for future value-added maintenance services.

Recently, a service engineer visited a client site as scheduled to perform a pre-startup inspection for three Hope Deepblue direct-fired hot and cold water chillers, which are used to meet the client’s heating and cooling needs in the factory and office areas. Upon arrival, the engineer briefed the client’s equipment manager on the visit’s purpose and scope, carefully listened to the issues reported, and began a thorough inspection.

The root cause was identified as a blockage in the filter between the external cooling water tank and the make-up pump, leading to insufficient water supply and resulting in intermittent protective shutdowns. After resolving the issue, the engineer also provided comprehensive training on routine maintenance procedures, including mode switching and vacuum pumping.

This follow-up visit allowed the client to experience the professionalism and responsiveness of Hope Deepblue’s after-sales service firsthand. The client expressed high satisfaction and gave a favorable score in the customer satisfaction survey, recognizing the team’s efficient and comprehensive support.

Hope Deepblue remains committed to delivering customer-centered service and strengthening brand trust through every detail of its support efforts, ensuring reliable performance for clients and promoting high-quality HVAC solutions.
