Window AC / September 8, 2018 / Babette Arsenault
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.
A window air conditioner is supposed to stay in place. This is different from a portable unit which rests on casters so that you can roll it from room to room. In most cases however a window unit will provide better cooling at a lower price that what a portable air conditioner can offer. Moreover you can install a window unit in each room if necessary. By many estimates having two or three window units is still cheaper than investing in a central system. When you are choosing a window air conditioner it is a smart idea to take measurements of the room you plan to cool.
