Window AC / August 31, 2018 / Aubrette Dumoulin.
I have seen many units that are not even screwed fast. If the window air conditioner is just there balancing in the window frame it becomes very inviting for a unexpected guest. The window air conditioner is also very inefficient. These units use more power per BTU of cooling than any other type of air conditioner. If you are a light sleeper than chances are you will not want one of these window shakers. Window air conditioners are one of the loudest forms of air conditioning. The blower for these units is very loud when running. Then add the noise of the compressor and you have enough decibels to keep many people wide awake all night long.
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.
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.
If the room is shaded then you can decrease the BTU rating you calculated with the climate control unit calculator by 10 percent however if you wish to cool a kitchen youll need to raise the rating by 4000 BTUs. When the room you are cooling is used by two or more people add six hundred BTUs per person to the rating necessary to cool the room. Before you buy the first air conditioner that fits the BTU rating necessary to cool your room make sure you have a window that will be suitable for the unit. Measure windows in the room (make sure not to block fire escapes) and make sure to buy a window air conditioner that will fit into the opening.
