A/C noise?

jhale2004 · May 24, 2012

Anyone have an idea what this noise is? A/C clutch or bearing or something?

Assuming you mean the rattling sound, it is classic aged/worn compressor sound. If you mean the short screech when the clutch kicks in, it is normal.

Yeah the rattle. So it's the actual compressor and not the clutch? It still cools fine after I charged it a couple months ago. Will it kick the bucket soon or still last awhile?

It is a little hard to tell not being there but it sounds like the compressor itself. When the clutch is engaged, there really isn't anything in the clutch to make noise that I know of. As for how long it will last, can't say. I've had them run for years like that - or not.

Well today it's hardly cooling. Added 12oz of 134a and no different. Should I plan on having someone do a new compressor, drier and orifice tube for me or is it something the average guy can do?

This kit looked priced well? The parts at local oreillys were 200 for compressor and 26 for drier

It's not extremely difficult if you don't mind turning wrenches. You may want to bring it to a shop after install to have a vacuum pulled on the system and let them recharge. That is the proper way to charge a system and they can more precisely fill it for better performance. Pulling a vacuum help rid the system of potential contaminants.

Im sure I can install the compressor and drier no problem. I like your idea of letting them vacuum and charge the system. What about the refrigerant that is already in the system do I just let it run out?

You are supposed to remove the refrigerant and capture it, not something you can likely do. Installing the receiver/dryer, then driving over to the shop to get the system recharged is not the wise thing to do. The receiver/dryer has desicant inside it to capture and retain moisture. Leaving the system in a non charged state will contaminate the desicant. You may want to remove the old receiver/drier, install the new one, and leave the plastic caps on the new one, not connecting the lines. Once you get the shop, either have them connect the lines or you do, then vacuum and charge. You will also want to use refrigerant oil on all the o-rings as well.

That kit also comes with a new fixed orifice tube, you may want to have the shop change that for you, they can be a real bitch to get out unless you have the puller for it.

I've heard that these reman compressors hardly last. Local shop said they would install new drier and a new Delphi compressor for 475 and guaranteed for a year. I'm leaning towards letting them handle it.

Me personally I would go that route. I can handle the mechanics, it's the refrigerant end that I don't have the proper tools/set up to handle. Hopefully my AC won't need major repairs any time in the near future...I hate Georgia heat/humidity...
