About Window Air Conditioners
On days where the weather is uncomfortably hot, placing an air conditioner in a suitable window can provide a cool relief. These window units are readily available for sale in most appliance stores, and are moderately priced, making them more affordable than alternative cooling systems such as central air cooling systems, wall units and portables.

Size
-
When it comes to keeping a home cool, it is important to purchase the right size of air conditioner for the job. Your decision should be based on room size as well as the size of the available window in which the unit will be placed. The larger the room, the stronger the cooling capacity needs to be to cool it. This capacity is measured in BTUs (British Thermal Units), which is the standard for measuring heat energy.
Function
-
Wall air conditioners work to decrease the humidity and force the warm air outside. The air conditioning unit works independently (aside from the need to have electricity in order to run it). An evaporator coil works in combination with Freon and a condenser to cool the air that enters the unit. A blower then pushes the cold air around, eventually cooling down the room.
Considerations
-
When choosing a window air conditioner for purchase, consider the energy costs involved in operating the unit. Noting the EER number listed on the unit's packaging will give you a good idea of just how energy efficient the unit is. This is the Energy Start rating, and the higher the EER, the more you will save on your energy bill.
Misconceptions
-
Some may be impelled to purchase a larger window air conditioner than is necessary, in hopes of keeping the temperature of the room extra cool. Not only is this a bad decision, but it just won't work. A window air conditioner unit that is too big will not work efficiently, and as a result will cost you a bundle on your electric bill. It will also cool a room too quickly, fail to remove the humidity and leave the overall moisture level in the room too high.
Prevention/Solution
-
Window air conditioners that are not maintained properly can cause poor air quality conditions in the home. Allergens, dust and pet dander can clog the unit's filter, forcing these damaging air particles throughout the rooms in your home. As a result, health concerns such as severe allergies and bronchial problems can occur. It is best to clean the window air conditioner's filter regularly by rinsing it under warm water and allowing it to dry thoroughly.
