When I turn the unit on, there is a very loud guttural sound coming from the motor which never goes away. 9/10 on a 1/10 scala.Also, a faint tinny sound is detected from inside the motor. At low speed, the motor occasionally changes speed with no apparent reason.

I don't know if I ever installed a sound system to any concert fan who didn't ask me this question. So how loud can I safely play my sound system?
If you have a receiver or amplifier that has an analog dial that goes from 7 o'clock to 5 o'clock the majority of units will output maximum volume at around 1 o'clock assuming a line level signal is sent to it (again it varies a lot from piece to piece). Anything higher then that and the unit will send out a distorted signal colloquially referred to as "clipping". Most modern units now use digital volume controls and everyone is different. The only way to detect this distortion is listen to when the music sounds tinny and harsh instead of clean and musical.
If you do not find it is loud enough for your liking you must invest in a more powerful amplifier or higher efficiency speakers; or you will continue to destroy your innocent speakers and blame them for your over driven amplifier.
Hey there, sounds like the bearings seized in your fan motor. You need to replace the fan motor. If the compressor runs without the fan, th pressures build up and if they reach an extreme point, the compressor will bypass internally, creating a loud sound as the high pressure is released to the low pressure side. I would turn the thermostat on and stand by the outdoor unit as it start. Leave the disconnect on the wall readily available so you can quickly turn it off. If the compressor sounds ok when it starts up and runs for a couple seconds, turn it off right away and replace the fan motor and you should be good to go. If the compressor sounds bad or real noisy immediately at start up, the fan motor not working killed your compreesor. You would need a motor and compressor, might as well replace the unit at this point if you are paying to have it done. Let me know if you need anything else seth
