AC condenser unit howling
My AC is making a howling noise and it has been since I moved here about three months ago. It hasn't gotten any worse and it seems to work just fine, but I suspect it's going to crash soon.

Any ideas? (Lennox model 13ACC-042-230-01)

Hard to tell from the video but it sounds like it's the fan.
Is the fan coming up to full speed and moving a lot of air ?

Yes, it's blowing fine. I guess I could briefly disconnect the fan and see if that does it.
