There is a lot of information on the internet about the efficiency of an air conditioning system. Most portable air conditioners operate with an Energy Efficiency Ratio (EER) in the 5 to 7 range.
Window air conditioners are slightly higher (usually between 8 and 9). However, it is important to note that a device's EER rating may or may not determine its true energy savings. How you use your device can determine the greatest energy-saving benefits.
For example, if you are trying to cool only one room, a window air conditioner is perfect and you can take advantage of the higher EER. Conversely, if you rely on this air conditioner to channel cool air into a neighboring room (eg a conservatory, bar, or dining room), you can lose a lot of energy trying to cool the area.
It is important to note that the portable air conditioner is equipped with a single drain hose that leads to a flat window adapter bracket on the back of the module which can be easily installed in a double-hung window.
