I am so pleasantly surprised with the quality and functionality of this portable air conditioner unit. We have central air, but the place we live has the sensor in a downstairs hallway where it's always cooler than the upstairs, where the afternoon and evening sun shines so brightly in the back bedroom window. Thus, when it's 72 downstairs in the dark hall, it's as high as 82 in that room. We got this unit to cool down the bedroom at night and it's so perfect! We borrowed a big name brand unit last summer when our HVAC system went down and needed a replacement, and that was loud, the hose was short, and the window needed to be 1/3 open to accommodate the hose. This unit, for a much better value, is quieter, cools so much better, and is much easier to move, and only takes up a sliver of window area. We sleep so much more comfortably with this running, and it only takes maybe 15 minutes for a room that's about 14x16 to cool from 82 to 72. This unit is so impressive for its size! The hose was a challenge to get the ends in place because it's a thin cheap plastic with no metal fastening rings at the ends, but it's holding ok. I might consider replacing it eventually, but it's working fine. The remote makes it easy to adjust the temperature without getting up, but also, there's several functions that might help others that we don't need like dehumidifying and it can just work as a fan. We have only used this on low, even when it was 95 out, but it also has a high setting. It also has a timer function, which we also don't use, since our preference is set to a temperature threshold. Definitely an excellent value for this workhorse!
