Many people do not know how to set up a window air conditioner and therefore just allow their homes or offices to remain sweltering during the summer. Window air conditioners are great because they are the least invasive air conditioning systems to install and can very easily be turned off or removed as is needed. They are easy to put in and should come with descriptive directions and charts. However not all directions give little tips and tricks. The first thing you should do is make sure to install it during the day. Daylight will make it easier to see what you are doing so it does not fall out of the window and it will also keep bugs from entering while the window is open.
If you live in a college dorm studio apartment or a one-to-two bedroom apartment a window air conditioner is probably your best bet for keeping cool during the summer months. Unlike a central air conditioner a window unit can cost under $200 and will do an excellent job keeping your place cool during the dog days of summer. A window air conditioner - as the name suggests - sits on your window in a semi-permanent installation. This type of unit is designed to work straight out of the box and requires minimal hassle when installing to the window. Basically you attach the unit to your windowsill and then close the window down on top of 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.
