Windmill Air

The windmill whispertech AC unit has been better than expected. Crazy simple installation. Looks aesthetically pleasing as advertised. The biggest and best thing about this window AC is that it blows the cold air upwards at a slight angle. Hot air raises and cold air sinks which means this unit does a wonderful job cooling my bedroom. My previous unit was a different brand that I kept running continuously at 62 degrees on high as it blew the cold air straight out and past my bed. Set at 62 degrees the previous AC unit would only cool the area of my bed in the upper 60’s to low 70’s. The Windmill unit I set at 65 degrees on low, sometimes medium an my entire bedroom is constantly nice and cool. Everything great so far. All I need next is time to see if this unit is built to last.

EDIT: hitting the RESET button on the unit (by the power outlet) seems to have fixed at least the app reading the inaccurate room temperature!! Posting this at the top so hopefully others see it first. But now it’s completely different. (I mostly use the app to turn things off and on, or change temps, I don’t do any automations.) The app always says the room temp is 73, and I can tell you it’s definitely not. It’s said that for a couple weeks and doesn’t change. The unit itself takes awhile to cool down the room, and sometimes runs for a long time (over an hour). Sometimes I eventually set the temperature higher just so it’ll turn off. Moving the temperature sensor definitely helped, but that shouldn’t need to be done. I’ve found that I run the unit even when I’m not home, so it doesn’t have to work as hard when I come home from work. Again, everything was fine last year. I genuinely don’t know what happened, but in reading other’s reviews, it sounds like I’m not the only one experiencing stuff like this. It sounds like deleting/reinstalling the app won’t fix anything, which is disappointing. The only reason I’m giving this app two stars is because of the excellent customer service. They’ve helped me fix the temperature sensor and sent me photos of how to move it, as well as other issues. They’re responsive and kind.

Sure, it's better looking than most window units, but I bought this for the app and scheduling capabilities. It's completely useless in that regard. Automations almost never work and turn the unit on, and on the rare occasion they do turn it on the settings have never once worked. It turns on at the lowest fan speed and eco mode. It's the same when I turn it on from the app. It shows fan on high and cool mode in the app but the unit is in low and eco. I have to switch each to a different setting and back to my desired setting for it to work. Absolute failure as a product unless they update their tech quickly. I've missed my opportunity to return this as it only recently got warm enough to actually use the automations and discover these fatal flaws. Edit: The app no longer controls the unit at all so it's gotten worse, but I've also discovered another serious flaw. If you lose power, when it is restored the unit does not power back on. Our older "dumb" one did, and I thought the long beep it made waking me up was annoying. It's far worse to wake up some time later because your bedroom has gotten hot. We don't lose power often, but get the occasional very quick outage during a thunderstorm and it's annoying. Will definitely not be using this AC unit again next year.
