During a recent service call at a gift shop operating a ducted split system. The outdoor unit was found heavily iced, particularly around the suction line and compressor section. Based on inspection and operating conditions. The likely root cause was restricted airflow across the indoor ev***rator coil. This is commonly caused by clogged filters, dirty ev***rator coils or blower performance issues. When airflow is insufficient the ev***rator temperature drops below freezing. Leading to ice formation that eventually extends to the suction line and outdoor components.

After isolating the fault. Our team inspected the indoor unit through the ceiling access panel. Assessed coil condition, checked blower operation and evaluated refrigerant parameters. Corrective servicing was carried out to restore proper airflow and system balance. Eliminating icing and stabilizing performance.

Key Technical Points:

1) Ice formation observed on suction line and compressor area of outdoor unit.

2) Root cause: restricted indoor airflow (dirty ev***rator coil / clogged filters).

3) Low ev***rator temperature leading to coil freezing and suction line icing.

4) Complete indoor inspection performed through ceiling access.

5) System restored after airflow correction and operational parameter verification.

13/02/2026

During our recent site inspection at a hypermarket facility operating 14 ducted split units. We observed active water dripping from multiple indoor units. Upon technical assessment, it was evident that the systems had not undergone servicing for an extended period. The ev***rator coils and filters were heavily clogged with dust accumulation, restricting airflow. This resulted in low ev***rator temperature and subsequent ice formation on several outdoor condensing units. The primary root cause was airflow obstruction leading to coil freezing and condensate overflow.

Key Findings & Technical Points:

1) Severe dust accumulation on ev***rator coils and filters due to lack of periodic servicing.

2) Restricted airflow causing low suction temperature and coil icing.

3) Ice formation observed on multiple outdoor units.

4)Condensate drain overflow leading to indoor water dripping complaints.

5) Immediate recommendation for complete chemical cleaning, airflow restoration and preventive maintenance scheduling.

We attended a complaint for a supermarket chiller that was unable to maintain the required 5°C temperature, directly affecting product storage conditions. Upon inspection, we identified a completely blocked drainage line caused by plastic particles and heavy ice accumulation.

Our team safely melted the ice formation, cleared the drainage blockage and carried out a full inspection of both indoor and outdoor components. The control panel wiring was also reorganized and properly set, as it was previously untidy and improperly arranged. After restarting and monitoring the system, the chiller stabilized and successfully maintained the required 5°C operating temperature.
