Window AC / August 24, 2018 / Aubrette Dumoulin
To ensure efficiency use weatherstripping or calk to seal any gaps between the unit and the window frame. Once youve finished installing your cooling appliance youre ready to sit back relax and enjoy your home again. Air conditioning can help you sleep better and enjoy your house more fully in the Summer months. If you would like to cool your entire house contact an HVAC technician about installing a central cooling unit but until then the window unit will help your family stay cool. What one sees of a window air conditioner from the outside is the sleeve a metal box with ventilation louvers that houses the actual air conditioner.
One sees a similar box for a wall air conditioner. Naturally people assume they are the same. But they arent and this article will explain why. The two types share some characteristics. Both span the dividing line from inside to outside allowing all components to be housed in a single box. Therefore both utilize both inside and outside air to perform. Both are designed to condition a single room. But there are differences. Windows are thin and the sleeve for a window unit is designed to take advantage of this. It sits on the window sill with the window closed onto the case to seal the top.
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.
