Analysis and Repair: This is a newly installed air conditioner. During inspection, it was found that when the machine was turned on to cool, there was an abnormal sound. However, within the first 3 minutes of starting up or in the fan mode, no abnormal sound was detected. After the compressor started, there was an unusual airflow sound from the indoor evaporator, and it was quite loud. Upon inspection, it was discovered that both the high-pressure and low-pressure connection pipes at the indoor unit pipe joint were flattened. After replacing the connecting pipe, the cooling function returned to normal.
Tip: In cases where there is an airflow sound, the main cause is usually poor circulation of refrigerant, so the focus should be on checking the flattened parts of the connecting pipes.
