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.
Another Energy Star rated air conditioner from GE is the AEM08FM window unit. With a BTU 8000 this GE Air Conditioner has an energy saver feature making it much easier to save on your electric bill. It also comes with an electronic thermostat. This GE air conditioning unit also has strong reviews to back it up. Owners note how this product is also very quiet. If you have a big room to keep frosty go with the GE ASQ12AK Window Air Conditioning system. this Energy Star rated appliance does not skimp on quality. Figuring it effectively can keep a big room cool and at the same time be energy efficient this really is a bargain.
Have everything ready and laid out before you have unpacked. Have the screen removed from the window. Remember that these only work for windows that can be pulled up. Ones that crank out will not open wide enough nor will they have anything to hold the air conditioner steady. Open up the window as wide as it can go to give yourself a little extra room to work. It is helpful if you have someone there to push down the top sash when the time comes. Make sure the air conditioner is facing the right way. The front which should be inside the room should have the dials and the cord to plug into the wall.
