Window AC / September 16, 2018 / Denise Brisette.
If you live in a college dorm studio apartment or a one-to-two bedroom apartment a window air conditioner is probably your best bet for keeping cool during the summer months. Unlike a central air conditioner a window unit can cost under $200 and will do an excellent job keeping your place cool during the dog days of summer. A window air conditioner - as the name suggests - sits on your window in a semi-permanent installation. This type of unit is designed to work straight out of the box and requires minimal hassle when installing to the window. Basically you attach the unit to your windowsill and then close the window down on top of it.
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.
If you spend over $300 on an air conditioner the quality and value increases dramatically. The air conditioners have a high EER and BTU capacity and are capable of cooling large spaces very quickly. Spend $600 or more and youll be purchases a super deluxe model that will probably cool your entire first floor living area. Odds are that if you own an air conditioner you own a window unit. These are the most popular types - both in the US and globally - available today. Window air conditioner units are so popular because they are inexpensive (running anywhere from $150-$600) and take up no floor space in your home because they sit on your windowsill.
An additional benefit of a properly sized air conditioner is humidity control. While these units are operating moisture condenses on the evaporator coil just like a dehumidifier. Probably the most common problem with window air conditioners is that they sometimes develop rattling noises due to vibration. This is not a serious problem and can be rectified very easily by checking to make sure all screws are tight and check that the unit is mounted correctly in the window and not twisted or stressed. Air Conditioning is something that many people look at installing every year. There are many options when it comes time to make that decision.
