The Advantages of window air conditioning units: They are cheap. Compact. Sometimes provide partial ventilation. No installation required. Easy transportation from place to place. Suitable for apartments summer cottages and offices. Window air conditioner can be easily installed in a shop on wheels. Another important advantage is long lifetime: window air conditioners seldom get to a service center mostly after many years of usage (the simpler the system - the more reliable it is). The disadvantages: High noise level. They block a part of the window stealing the daylight. The window frame must be altered.
Today window air conditioners are becoming less popular then wall split-systems. And it happens for several reasons. These air conditioning systems are indeed much noisier than split-systems and they significantly reduce the daylight area. But besides some disadvantages window air conditioners have decided advantages. The main advantage is reasonable price. Another important factor is easiness in installation and relatively small amount of Freon in the system. Modern device models provide intensive ventilation and air conditioning and are characterized by economical operation.
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.
