Window AC / September 13, 2018 / Marphisa Babin
If you already have a window air conditioning unit and you have noticed recently that it seems to be louder there are few steps you should take. Check to see if the unit is vibrating on the windowsill. It may need to be re-tightened on its shelf. The side panels might also be loose. Inspect those to see if they need tightening. If the unit seems to be vibrating more than normal consider sliding a piece of wood under the unit to secure it.

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.
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.
