I live in Oregon, where sometimes it gets 100F+ degrees in the summer. My condo does not have central air and I am not allowed to have a window unit, so I worried about a portable unit that could keep my place cool enough for my dog. This unit has done an EXCELLENT job…. The fact that I can see the temp of my home from my phone while at work is reassuring, and I know my dog is comfortable. I can control the temp, vent swing, and mode all from my phone when outside my home. This is great product, I highly recommend!
