What Causes Unusual Noises in Car Air Conditioning?

[HazelFitz]

Unusual noises in car air conditioning can be caused by the following reasons: 1. Damage to the car air conditioning compressor: This may be due to lack of lubrication, worn shafts, inability to compress air normally, or air leakage. When the air conditioning compressor has problems, the car's air conditioning system may produce unusual noises or fail to cool. 2. Blocked air conditioning vents: The air conditioning vents need to be cleaned promptly. It is important to note that the car's air conditioning filter should also be cleaned and replaced regularly. Generally, it should be cleaned every 5,000 kilometers driven. 3. Worn fan blades: If the fan blades are worn, the fan bearings lose lubrication, or the fan blades are stuck by foreign objects, the car air conditioning may produce unusual noises. In this case, the fan blades need to be removed for detailed inspection. 4. Engine noise: If the engine belt is loose or produces noise due to other reasons.
