Air Conditioner making knocking and wobbly, unstable noise.

Hello. I have a Haier window air conditioner unit, an energy star series. Model number ESA306. When itís running on high it is pretty loud and makes a wobbly fan or weird fan bearing type noise that makes it sound like something it just out of place. Almost sounds like a ďchuggingĒ noise with occasional vibration of something inside. On medium it sounds about the same but a tad quieter, and on low it makes a loud knocking noise like the fan is about to fall off. I just picked up this air conditioner to see if it worked, I found it in the lobby of my apartment- someone was going to throw it out. It blows cold air and the thermostat is accurate, but that loud fan noise is just too much. Any ideas?

Now you know why it was about to be thrown out.

Based on your description it sounds like the fan bearings are worn out.
Unfortunately the availability and cost of parts do not make this a worthwhile repair.
Also, many of these units are extremely difficult to take apart and are made to be disposable.
But, you have the unit and it's free......try taking it apart and see if it's worth the trouble.
