What Causes Loud Noise in Car Air Conditioning?

[MollyAnn]

Reasons and solutions for loud noise in car air conditioning are as follows: 1. The amount of refrigerant added exceeds the standard: This increases the load on the compressor, leading to higher stress. Solution: Check the air conditioning inspection window. When the air conditioning is on, if liquid flows through the window with a few bubbles, the refrigerant level is normal. If there are no bubbles, it means too much refrigerant has been added, and the amount should be reduced appropriately. 2. The added refrigerant is inconsistent with the original refrigerant. Solution: Replace the refrigerant. 3. The compressor belt is too tight or too loose. Solution: If it's too tight, loosen it; if it's too loose, tighten it.
