Window AC / September 5, 2018 / Lundy Brochu
Window units of today are very quiet and their efficiency has improved a lot also. In fact these units are so quiet that you can hardly even hear them operating. Window air conditioners have the same components as a central air conditioner but they are all installed in small cabinet. The biggest and most important difference is that they dont have to cooling capacity of central units. But they also dont cost as much to operate either. If you only want to cool one or two rooms then window air conditioners are a perfect choice. However if you want to cool your entire home a central air conditioner is the best alternative.
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.
You can not block the air conditioner with curtains for example; otherwise the comfort will be created between the window and curtains but not in the room. Less effective in a larger room. Sometimes price is much the same as of the split-system. One must admit window air conditioners design more compact and reliable compared to split-system. Window air conditioning system consists of a single case. This so-called monoblock is mounted into the window opening or wall. The conditioner case is a big box assembled from metal plastic panels of white gray light brown or other pastel colors. All the filling of indoor and outdoor units of split-system (evaporator condenser compressor fan etc.) is inside the case. There are no any external connecting tubes.
