I took the back off and vacuumed out the "fins" that were clogged with dust. It seems to be cooling, the exhaust tube in the back is getting warm and definitely blowing warm air through it. Cold air is coming out through the top/front. When just on fan, it's nice and quiet. A/C kicks in and its a loud rumble-ish sound (not a squeal) And not what I know window A/C unit compressors to sound like. I'm guessing it's the A/C blower? Or the compressor itself?
Check vibration eliminators on the feet of the compressors, over time of running in tough conditions they wear out and cause rattling. If this does not fix the problem see below
-check amp draw, if amp draw is high windings are wearing out and compressor is running harder, may need replaced
- check to make sure your refrigerant charge is correct you could be slugging the compressor
-find other ways to isolate compressor operations

It is probably either the high pressure switch or the frost control. The high temp switch usually trips because the condenser coil is dirty which does not allow it to exhaust heat very well. The frost control will trip if the system gets below 39 degrees on the pipes. This is usually do to low refrigerant or dirty filters. Good Luck!

buy a new effecient A/C
I had the same problem but it was my bedroom one so I swapped out my living room A/C into my bedroom and put the new one in the living room.

I JUST BOUGHT A 9000BTU PROTABLE AC MY QUESTION IS IF I REDUCE THE EXAUSTE FROM THE ORIGINAL 3" TO 2" WILL IT BECOME A PROBLEM WITH THE AC OR MALFUNCTION
SOURCE: Unit not blowing exhaust!!!
http://safemanuals.com/brand-user-guide-instructions-owner-manual/MAYTAG, this may help you locate the issue. there may have been some degris that is keeping the blower cage from turning, or the cage may be damaged.

It sounds like the compresor is trying to start but it can't ( it could be burned out or stuck) But before replacing the compresor put a booster in parallel with the capacitor ( is no more than $30) it will help the compresor to start ,if doesn't , it has to be replace.
