Professional Chiller & HVAC Maintenance and Servicing Procedures

Chiller & HVAC System Inspection and Assessment

The maintenance process begins with a comprehensive system inspection, covering everything from cooling coils and ductwork to equipment such as compressors and AHU/FCU fans. Based on the assessment results, the technical team develops a detailed maintenance plan, ensuring no critical aspects are overlooked.

Key Maintenance Tasks for Chiller Systems

1. System Cleaning and Inspection: Each Chiller and HVAC system will be cleaned, inspected, and have operating parameters measured periodically (twice a year), based on manufacturer recommendations and actual operating conditions.
2. Scheduled Maintenance: Maintenance services will be performed regularly and clients will be notified at least 5 days prior to execution. Maintenance schedules will comply with Vietnamese labor safety regulations.
3. Component Replacement: Component replacement will only be carried out with written or email consent from the client if components or equipment are damaged, aged, or no longer functional.
4. Response Time: Khoi Minh commits to on-site presence within 48 hours to inspect and repair Chiller and HVAC system malfunctions.
5. Warranty:
   • Free labor for troubleshooting during the maintenance contract period.
   • 12-month warranty on replaced parts, applicable to product defects or issues caused by Khoi Minh's personnel.
   • The above information is designed to ensure prompt, efficient service and compliance with safety regulations.
