Car Air Conditioner Noise - 2005 Toyota Echo

I am just after some quick advice from someone who knows more about cars than me.
My 2005 Toyota Echo recently started making an almost grinding noise when the air conditioning is switched on. This didn't sound that bad from inside the car, but is quite loud externally. The sound appears to be coming from the left side of the engine bay but I was having a difficult time identifying exactly where.
I've recorded a short video of the sound when the air conditioning is on and off.
Due to the cooler temperature, I can't really tell if the aircon is working or not, but from what I can feel the air coming from the vents isn't noticeably colder with the ac switched on vs being just fan. Also, this sound doesn't occur when just the heater is on.
The sound doesn't appear to go away even when leaving on, and does seem to increase in loudness when the car is at higher revs.
From what I can gather, the likelihood is that the aircon compressor is going or is gone already. I haven't gotten any formal quotes but this seems like it would be expensive to replace, and given the age of the car I am not sure I would want to spend that much on it.
I might take the car to a service yard on the weekend to see if they can diagnose, but any advice is appreciated.
