Why does the 10th-generation Civic make a water flow sound when the air conditioner is turned on?

[EleanorMarie]

Here is a detailed explanation of the reasons and solutions for the water flow sound when the air conditioner is turned on in the 10th-generation Civic: 1. The gurgling sound from the indoor unit of the air conditioner is the normal vaporization and refrigeration process of the refrigerant in the pipeline: It is normal to hear a slight flow sound of the refrigerant when the air conditioner is cooling, especially when it is just started. As long as the water flow-like sound is not too loud, it should not be heard after stable operation. 2. The sound caused by the vibration of the indoor unit fan: Secure the air outlet louvers properly and clean the filter screen. 3. The sound of the semi-fluid refrigerant flowing in the pipeline: This is not a problem, but you can also adjust the liquid outlet valve to resolve it. 4. A flattened copper pipe can also produce a gurgling or water flow-like sound: Replace the copper pipe.
