Rattling or your car air conditioner making loud humming noises which get worse as you accelerate can both be signs you need to replace your ac compressor. If the serpentine belt is worn it can slip when the compressor engages causing noises. In this situation the buzzing sound is caused by liquid refrigerant entering the compressor intake port. If loose tighten them but check the inside panels before the outside panels.

The loud noise when the ac switches on is another potential symptoms of bad ac compressor. Then check all exterior and internal panels. In this scenario people might try adding refrigerant on their own. Again start by turning the ac unit off with the cb disconnect and with the thermostat.

If your ac compressor is beginning to fail it can make a rattling noise. This high wear part often needs replacing especially if you live somewhere where you re constantly running your car s ac. Normally you should hear or feel nothing when the air conditioner is working except the cold air coming from your car s heating cooling ducts. A buzzing noise from the compressor when the air conditioning clutch is engaged is a sign of an overcharged system.

If that refrigerant floods into the compressor crankcase then you are going to have some additional noises possibly.

Bad car ac compressor symptoms ac compressors endure a lot of stress. Your air conditioning compressor has a refrigerant which is responsible for keeping the temperatures within at a manageable level. Itâ s possible that the noise is actually from the idler pulley if its bearings are failing. If you have isolated the noisy air conditioner to your condensing unit the outdoor one or packaged unit itself.

Over a certain number of years this stress will wear down the compressor and cause it to eventually malfunction. If the compressor pulley bearings are failing they can make noises generally a grinding roaring or squealing noise.
