Window AC / September 16, 2018 / Denise Brisette
The back the part that hangs outside should have the vents where water will drip out. Carefully place it on the window sill facing the right way. There should be ridges around the perimeter of the air conditioner to show you where it should line up with the window. Once you have this lined up slide open the side panels. These are designed to fill up the rest of the window that the device does not fill. Slide them as tightly over as you can. Have the top sash of the window lowered carefully and slowly down until it comes into firm contact with the top of the conditioner. The frame should be very tight against it to brace it and keep it from falling.
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.
The main aspect in the choice of window air conditioner is its cool air performance. You can approximate the required power at the rate of 1 kW per 10 sq.m. with a ceiling height of 2.8 - 3 meters; for household models the characteristic is: from 1.5 - 2 to 6.5 - 8.5 kW. If there is a large glass area in the room windows face south or there are other additional heat inputs one should better buy a model with a power reserve of 15-20%. Another important factor in choosing window air conditioner is room functionality. For example air conditioner installed in the kitchen must be of high performance to provide optimal heat control. Air conditioning unit for bedrooms should have low noise characteristics.
