Window AC / September 12, 2018 / Lundy Brochu.
They are also easy to install unlike split air systems and central ac. Installing a window unit is an easy DIY job that can be tackled in an hour or so. Also because they are installed in a semi-permanent fashion you just set it and forget it. Unlike portable ac units which are often wheeled around from room to room a window unit is designed to stay put. In spite of all of these benefits however window units have one major drawback: the noise. These units are loud and different models can range from being moderately annoying to downright deafening.
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.
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.
The most popular brands of window air conditioners in the US are General Electric LG and Friedrich. You can find these units at various big-box retail stores like Best Buy or Sears as well as at online at merchants like Amazon. The cost of window units varies widely depending primarily on how many BTUs you need. The smallest units can be as well as $180 with the larger units running up to $500. In some climates Summer months can be downright unbearable without an air conditioner. Window A/Cs are less expensive than central air cooling systems and they typically use less energy than whole house systems as well.
