If there is no central hot air heating then the installation of central air conditioning can be much more difficult. Many homes that do not have hot air heat also do not have the room to install ductwork. This would eliminate this possibility. If you are in this category you should get a professional to look at your situation to see if central air conditioning can be done. If it is the room available is to enough to do a good job and get large enough ductwork installed then do not force the issue and go another option. Ductless split type air conditioning may be your best option.
If you choose to use a window air conditioner than you should also look for a place that it can be secured and placed in a room that you will not be sleeping in. As you can tell by now I am not a big fan of window air conditioners. They do have a place for some people. However you do need to be aware of the problems that you may encounter with them. The low initial cost can be offset by the fact that they typically do not last as long as a central air conditioner. Central air conditioning will last much longer be quieter during operation be more efficient be more secure but the initial cost will be higher.
If you already have a window air conditioning unit and you have noticed recently that it seems to be louder there are few steps you should take. Check to see if the unit is vibrating on the windowsill. It may need to be re-tightened on its shelf. The side panels might also be loose. Inspect those to see if they need tightening. If the unit seems to be vibrating more than normal consider sliding a piece of wood under the unit to secure it.

The answer is It depends on the wall thickness. Sleeve specifications for some window air conditioner manufacturers include the maximum wall thickness before it will cover part of the louvers. For example Amanas 18000 BTU models have a max of 8.5 inches. If the wall thickness is at or below that these models can be used in as a wall air conditioner without adversely affecting function. So whats the problem if the wall covers a little of the louvers? Two things: 1) restriction of air movement and therefore reduced efficiency and 2) these units pull air in very powerfully. Cut wall edges could become loose allowing material to be sucked into the unit and potentially causing damage.
