Portable air conditioners generally consume less electricity than regular air conditioners, since they do not cool an entire building. By restricting air conditioning use to a single room, consumers can save a substantial amount of money on their energy bills.
To increase savings even further, consumers can use their portable air conditioners in conjunction with an electric fan, which can lower the room temperature by 4 degrees Fahrenheit.
Most portable air conditioners include built-in timers that allow owners to determine how long the machines should run. This feature is useful when the owners are preparing to go to bed or leave the area.
