Supplier typeThe supplier operates in HVAC-related trading, design, installation, maintenance, and after-sales services, with products including ground-source heat pumps and large-scale central air-conditioning equipment.

After-Sales capabilityThe supplier reports 10 professional after-sales personnel, 10 after-sales service vehicles, a sound maintenance and after-sales system, complaint-handling procedures with records, and documented corrective and preventive action procedures.

R&D capabilityThe supplier states that it promotes a transition toward high-tech, energy-saving, and environmentally friendly industries and offers design-related customization.

Its stated design team and ability to provide personalized design solutions further support a strong customization offering.

Client casesThe supplier states that projects have spread throughout Dongying since 2000, demonstrating a long local project history.
