AC compressor is making noises at low speeds?

Hello

I have a 2008 Pontiac G8. I replaced the ac compressor (3111PRO code reader) and ac condenser (Made in china) about 9 months ago.

The AC blows cold air, but the compressor is making noises when the vehicle at idle or low speeds and I'm sure it will fail very soon.

I don't want to repair the ac compressor because I already purchased a new one yesterday.

I will replace it by myself, make sure there is no leak, and charge it with Freon gas with 580 grams as recommended by the owner's manual book, but the question is

Do I have to change the AC Condenser again? The original Condenser costs about $290 and a cheap one is $80.

please advice!

Why change the condenser? All it does is sit with the radiator and allow heat to be exhausted off; if it's not damaged mechanically then why worry about it?

Do you mean the Air Drier? If you crack the system and get it back together like same day within a few hours and pull a good vacuum you shouldn't need to replace a BRAND new air drier.

If the COMPRESSOR is making noise why are you worried about the CONDENSER?
