Default Weird A/C Noise

Happy Independence Day (Especially to anyone from Great Britain! )

Recently, I noticed a strange noise whenever I turn on the A/C, it appears to be coming from under the hood.

It's a scraping/grinding noise, but it does not appear to be coming from the compressor, but more from the driver's side of the car. I'm stumped. The air conditioning still works fine, albeit a bit low on refrigerant, but that's a project for another day. I initially thought maybe the fan was hitting something, but it does not make that noise at any other time. Coolant gauge always stays exactly in the middle and I can hear the compressor cycling on and off at the appropriate times.

I have no idea what would cause that, though it doesn't appear to be "Life Threatening"

Sounds like the clutch on the compressor may be starting to go bad

Does it do the noise when you start the engine cold and turn on the A/C?
