Window AC / September 20, 2018 / Marphisa Babin
Another huge improvement in window air conditioners is in their appearance. Older models did not blend in very well with their surroundings. They were usually some shade of brown and looked like there was a box in your window. Window air conditioners today are much less obtrusive and look less like boxes. Corners are rounded and colors are much lighter. This gives them a much sleeker look. As with most things once they have been around for awhile cost become more reasonable and less of an obstacle. A window air conditioner can be purchase for less than two hundred dollars and often not much more than one hundred dollars. Of course this is for smaller units. Costs go up as the cooling capacity of the unit increases.
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 you choose to use a window air conditioner than you should also look for a place that it can be secured and placed in a room that you will not be sleeping in. As you can tell by now I am not a big fan of window air conditioners. They do have a place for some people. However you do need to be aware of the problems that you may encounter with them. The low initial cost can be offset by the fact that they typically do not last as long as a central air conditioner. Central air conditioning will last much longer be quieter during operation be more efficient be more secure but the initial cost will be higher.
