Poor cooling effect: may be caused by refrigerant leakage, poor refrigerant circulation, evaporator blockage, and other reasons. Need to check the refrigerant circulation system to ensure there are no leaks, clean the evaporator together, and remove internal debris and dust.

Poor heating effect: may be caused by heating element defects, blocked heating water tank, control circuit problems, and other reasons. Need to check the heating elements and heating water tank to ensure normal operation, clean the internal and external filters together, and ensure smooth water circulation.

Excessive noise: It may be caused by loose internal parts, compressor problems, unbalanced fan blades, and other reasons. We need to check the internal parts and compressor, and if necessary, we can replace the fan blades or adjust the balance.

Excessive energy consumption: It may be caused by equipment aging, inaccurate temperature setting, circuit defects, and other reasons. We need to check if the equipment is aging, and if necessary, we can replace the corresponding components or adjust the temperature setting.

Abnormal display panel: may be caused by control circuit issues, sensor issues, and other reasons. Need to check the control circuit and sensors, and if necessary, repair or replace the corresponding components.

Water leakage problem: It may be caused by evaporator leakage, condenser leakage, pipeline leakage, and other reasons. We need to check if the evaporator and condenser are damaged, and together, check if there is any leakage at the pipeline connection, and promptly correct the leakage problem.
