Window AC / September 20, 2018 / Marphisa Babin
When purchasing a window air conditioner it is very important to purchase one with the proper cooling capacity. An air conditioner that is not properly sized will not work as efficiently as one that is sized properly. This is one of the most common mistakes made when selecting air conditioners. Use an air conditioner size calculator to select the proper sized unit for the room you want to cool. Undersized air conditioners will run continuously and not cool the space adequately and an oversized unit will cycle on and off too often. This increases equipment wear and can actually cause fuses to fail.
There are other bells and whistles that are available on units these days. These can include features like dehumidifiers to remove moisture from the air and antibacterial filters which can remove odors and bacteria. A final issue to consider if you are looking to buy window air conditioner is what sorts of energy saving features the unit might have. You may consider looking for a unit that has an Energy-Star rating. The EPA assigns an Energy-Star rating to air conditioners that meet certain standards for being cost-effective and guaranteeing energy savings. This can help keep your electricity bills and check even during the hottest days of summer.
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.
