This Frigidaire air conditioner has been used for a little over one year now. It is mounted in the window for the hot summer months. It was very easy to install by two people. It plugs into an ac plug. There is a digital display for the temperature it is set at. There is a check filter light that comes on when the unit determines it is in need of a new filter. It just went on after over one year. You can set a timer and a sleep button for on/off. There is a cool mode, energy saver mode and a fan only mode. Also can set the fan for lo, med, hi or auto. Then an on/off button. This unit came with a remote control which has been incredibly handy. The remote is quite small and uses two AA batteries. The remote has all the features that are directly on the unit as far as functions to control. The vents can be adjusted up and down somewhat, but not necessarily side to side. The noise is very good for a window unit. I turn my tv up only one or two points when it is on compared to when it is off. Very pleased with this unit.
