Ac compressor making noise

There is a noise near the a/c compressor when the engine is running and the mechanic suggested that I replace it. Even though the AC is off it still makes a noise. I posted a video for more info on the sound.

If you hear this noise all the time, then it is probably the a/c clutch bearing, which will have to be replaced. More than likely, by the time you pay for the parts and labor to install the bearing it may be cheaper to replace the whole compressor.

Testimonial: "So even though the ac compressor isn't broken it's just the bearing that comes with the kit? Awesome. Did you listen to the sound though because it's actually quite unique in comparison to other sounds that other people notice."

SOURCE: Ac compressor. is making a ticking noice

This is normal, the compressor is spun by the fan belt, and when everything equalizes the pulley stops moving. This repeats over and over again.

SOURCE: 2002 Dodge Durango makes a noise when the ac is

It's the clutch or compressor or the idle pulley for the belt for the AC to check it have someone start it with the hood open and use a broom handle pressed to your ear and put the end of the broom near the ac compressor and turn it on and see if you here it there then shut it off and check near the idler pulley to see if it's there. The stick acts like a doctors stethoscope and amplifies the noise and will allow you to pinpoint the noise more accurately. If it is the clutch it can be replaced without replacingthe whole compressor but you will have to buy it at JC Whitney on line. Many who sell them charge as much as the compressor assembly costs.

I had the same issue with my 2006. I thought the compressor clutch bearings were faulty. After further research, the rattling noise was actually coming from the serpentine belt tensioner. Easy repair!
Hope this helps.

Good morning everyone! My marine AC unit is making noise- I'm not sure if is the compressor - suggestion anyone pls? Thanks!

You will have to open it up to see if it is the compressor or the fan motor. You will see the fan wobble when running. Replace the motor Could be the fan also.. If it runs true. replace the compressor. May be cheaper to replace the whole unit.

Chevy Aveo grinding noise from accelerator when A/C is on

It will be the ac compressor clutch that slipping when after it has been activated/engaged. This happens when the engine is winding up the compressor clutch is not engaging strong enough and start slipping. However as the engine rpm stabilize on the ac compressor has caught up (same rpm) no slipping occur and no noise. Was the clutch mechanism replaced with the compressor replacement? (however it need to be checked/repaired).

Yes in most of these instenses you can replace just the clutch assy. advance auto parts does offer it sepperatly. and they wont have to even open any lines. it just requires a special puller kit.

I have wining noise in engine that apears to be coming from ac compressor how do i repair same?

Are you sure. These noises travel very well and can trick you. Get a long metal extension, touch one end to suspected cause, with engine running, and the other to the small flap of your ear. If it is the bearing in the compressor special tools are required to replace it. Find a good mechanic for this.

Ac stopped working , smelled smoke, shut car off and on then ac worked fine but hearing odd roaring noise every now and then

Sounds like the AC compressor is going bad. Have the compressor tested and I'm sure the belt is what you were smelling. make sure nothing is touching the AC belt. If the compressor stops working properly the belt will burn. Solution= replace compressor and belt.

There is a squeal sound (high pitch) coming out of

The seal on the AC compressor has probably failed and allowed all the refrigerant and lubricant to be lost. This allows the bearing to run dry and now it is failing and making noise.

1. You could have the AC repaired, the compressor repaired or replaced and the system refilled.

2. You could have a mechanic disconnect the system and possibly remove the compressor (only if this model does not use a belt that relies on the compressor being in place).

3. It is probably way too late to try to refill the AC system with R134a refrigerant as it would just run out past the failed seals.

If anyone has an AC unit that just recently stopped making cold air they should attempt to recharge the unit (if it uses R134a - check your manual or underhood stickers). I just did and saved my compressor and AC unit from further damage.

Grinding sound when running a mechanic said its timing chain..

First question. IS IT NOISY ONLY WHEN THE A/C IS ON ? If yes , its the compressor, if not could ne the A/C compressor clutch bearing. Best found using a " mechanics " stethoscope such as a doctor uses to pinpoint the noise. Hope this helps
