Window AC / August 26, 2018 / Denise Brisette
If you spend over $300 on an air conditioner the quality and value increases dramatically. The air conditioners have a high EER and BTU capacity and are capable of cooling large spaces very quickly. Spend $600 or more and youll be purchases a super deluxe model that will probably cool your entire first floor living area. Odds are that if you own an air conditioner you own a window unit. These are the most popular types - both in the US and globally - available today. Window air conditioner units are so popular because they are inexpensive (running anywhere from $150-$600) and take up no floor space in your home because they sit on your windowsill.
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.
