No coolers or very little cooling even when the actual temperature is low enough
Check whether the windows open in the room. This can cause delays in the process of cooling the hot air will continue to raise the temperature. Close them if it is open. Oiling may lead to slip. So tighten or replace as needed. If the filter is clogged condenser, cooling will not be efficient. You also need to check whether any refrigerant leaks out.
The smell can mean many things. It can even mean a dead mouse in the air duct. So the air duct cleaning is as important as cleaning and wiping the cooling unit itself due to health reasons. If the condensed water does not have the proper outlet, then dripping in the cooling unit and become stagnant, provide odor.
Loose nuts and bolts are the main causes for the noise. Tighten bolts and nuts and see if any part in the AC were touching each other to make the noise.
