At least in the US, air conditioning / heating tends to be on the loud side, since the AC unit is mounted directly inside the room. Often times I resort to turning it off for the night to make sure I can get some quiet sleep. This is an issue in both cheap and middle class hotels - not sure if 5-star places have the same noise problems.
What's the reason behind this frequent problem? Is there a general expectation that such noise would not be an issue for most guests?

The "mini-split" units which are more common in Europe, where the compressor is outside the unit, are much more expensive up front than the cheap window units or floor units found in typical midrange or budget American properties. They also cost more to install.
- Window unit: $150
- Wall unit: $450
- Mini-split: $600 for the dead cheapest, plus likely drywall work.

Can AC outdoor unit be installed on closed room?
There should be ample space to place the outdoor unit. It should be placed in a clean, dry and open space. It cannot be placed in an enclosed space like a garage. It must be placed in an open environment for proper working.Why are you always told to close the door when inside an air conditioned room?
It is highly recommended that you close all windows and doors when the air conditioner is turned on. This will keep the cool air inside the room and keep the temperature moderate. In addition to cooling efficiency, leaving the windows open will also put stress on the air conditioner.Why do AC units have to be outside?
It removes heat from the air in your home\u2014and that heat needs somewhere to go. If it went back inside of your home, the process would be pointless. The outside unit gives the heat a place to dissipate.More answers regarding why don't hotels mount air conditioning units outside the rooms? [closed]
Answer 2
Well this is an air conditioning issue: cheap hotels use mono block air conditioning units, as it's cheap!
You can use also the double block air conditioning (or mini split), which is more expensive compared to the mono block and in this case you need to drill a big hole in the wall.
The five star resorts use central air conditioning: a big unit outside the building that provides cooling for the whole building (more expensive and requires high budget and maintenance).
Bottom line: mono block is cheap. (ref: Sylvane.com: Types of Room Air Conditioners)
Answer 3
One more reason that wasn't yet mentioned:
if you mount a monoblock A/C outside, it will disappear quickly - they are relatively cheap, but still worth stealing.
Answer 4
It depends on the position of the unit. High class hotels give special attention the the house while middle class hotels might not have sound proofing it take the sound into account.
