Window ACs generally use a double shaft fan motor with two separate blades attached. In those two, one blade is used for drawing air over the cold evaporator coil and circulate into the room. Another one is used to dissipate the heat from the condenser coil.
When your unit is on, the fan motor runs continually. After some time, the motor bearings/ bushes may damage and cause unusual squeaking, screeching, or roaring noises. If the filter is not cleaned regularly, the fan blades can build up dirt and slowly become unbalanced that will cause to damage the motor. For non-serviceable motors, you have to be replaced when they become noisy.

Usually, the fan blades are attached to a double shaft fan motor and are often connected to the shaft with a spring type of lamp. When this clamp is damaged or weak, it can't hold the fan blade hub securely to the shaft. Also, create an unusual noise when it vibrates so that check the clamps for a tight fit. You should replace it if need.
When your air conditioning unit working, it vibrates. Due to this vibration, screws of the unit to come loose. With the result of screws in panels throughout the AC, many of the problems that make noise will occur. Sometimes, mounting screws are also loosened when the air conditioner operates. Both situations will make a rattling noise. Hence, you may fix these with a little tightening of screws with a screwdriver.
