Window AC / September 11, 2018 / Jacqueline Bizier.
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.
Depending on the size and level of insulation of your home one window air conditioner is typically enough to cool one or two rooms but larger units may even be able to cool an entire 2-3 bedroom apartment. Using multiple cooling units in a home will allow each person in the family to keep their room at the temperature they desire. Installing a cooling unit will take anywhere from ten to forty minutes. Choosing the Right Air Conditioner
They are also easy to install unlike split air systems and central ac. Installing a window unit is an easy DIY job that can be tackled in an hour or so. Also because they are installed in a semi-permanent fashion you just set it and forget it. Unlike portable ac units which are often wheeled around from room to room a window unit is designed to stay put. In spite of all of these benefits however window units have one major drawback: the noise. These units are loud and different models can range from being moderately annoying to downright deafening.
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.
