I bought this unit to have for a backup if we loose power for an extended period of time. The power consumption is low enough to power with my generator. I have been using it nightly since installing (which was easy), I raised the temp of my central unit and only cool my bedroom. To my surprise in the ECO mode the unit actually shuts the fan off when the compressor is not running! Keeps my bedroom plenty cool enough on low and is really quite. Really liking the unit!
