We provided nationwide technical support services for Bank Asia branches across Bangladesh, focusing on electrical wiring inspection, troubleshooting, and maintenance activities. Our work included comprehensive electrical wiring checkups to identify faults, ensure system safety, and maintain uninterrupted branch operations. In addition, we carried out AC system troubleshooting and servicing to improve cooling performance, operational reliability, and energy efficiency. The maintenance activities were conducted through systematic inspections, fault diagnosis, and corrective actions tailored to branch-specific requirements. Our team ensured timely service delivery with minimal operational disruption while maintaining compliance with standard electrical and HVAC safety practices. Through this project, we contributed to enhancing the overall reliability, safety, and functionality of critical banking facilities nationwide.
