Windmill 5,000 BTU Lite Window Air Conditioner, Cools up to 150 sq ft

Very small, which means it will be very noisy

An absolute dream. I use it in a 10x10 office area where it gets it cool decently fast . The unit is extremely easy to set up and use, same with the app for it. When im on my way home I can turn the unit on and by the time I get home (about 20 to 30 minutes) im in a nice cool room to relax and hangout in. The power draw was the major priority when purchasing this unit it barely pulls anything and still works phenomenally. Id highly recommend this to someone who needs a unit for a small room who doesn't want almost any noise but wants to stay cool.

This AC is not as quiet as advertised. I have a Midea 10,000btu in another room and it barely makes a sound. This Windmill is compact and easy to install. Its Eco setting cuts down on the noise and energy. For the price, it's OK. I have to purchase another 5000btu AC for another room. Not sure if I would buy this Windmill again.

Easy install, light weight. The app is easy to use and set up. Cools a bedroom quickly. Removing 2 stars for the sound. I don’t mind a loud air conditioner. The sound it makes is inconsistent and scratchy. It sounds like metal is rubbing on metal. It is a an irritating sound. The filter is hard to put back in because there are wires that get in the way. Works well enough to not go through the hassle to return but would not buy again.

Easy setup. Despite it being pretty heavy, I was still able to install it alone. It fits snugly in my window and has a nice seal. I was able to fit it in my 21" W window, too, which I was pleased about. This is one of the only in-window air conditioners that can fit such a small window. The cooling is fast and strong. Completely cooled down my 120 sq. ft. home office within 10-15 min. It will make working in the summertime far more pleasant.

Feel terrible leaving 1 star, and typically don’t review anything but wow. I wanted to love this AC unit and thought it would be better then the basic one that came with the apartment (window unit), but major buyers remorse. It’s not only louder, it don’t cool the room (120 square feet). The automated screen is nice, but the sound and noises it makes…I haven’t slept thru the night without waking up multiple times and turning it off. I don’t understand how anyone could say this is a quiet AC unit. The noise (eco is the worst), not cooling down a small space, major bummer.

The installation instructions are very poor and I discovered a large gap under the unit between the window sill and the unit that I had to cover with tape. There should have been a YouTube video for installation.

⭐⭐⭐⭐⭐ Perfect for my small space, and it looks modern too. I’ve been using the Windmill 5K BTU in my studio apartment for about a week now and it’s honestly been such a great addition. I was worried it might not be powerful enough since it’s a smaller unit, but it cools my room super quickly. The setup was really easy, everything you need comes in the box, and I had it up and running by myself in under an hour. I also love how it looks. Most window ACs are bulky and kind of ugly, but this one actually blends in with my space and doesn’t stick out like an eyesore. One of my favorite features is the app. I like being able to adjust the temperature while I’m out, so I can come home to a nice, cool room. The lights on the unit also auto-dim at night, which is a nice touch when I’m trying to sleep. If you’re looking for a small, quiet, and modern-looking AC that actually works really well, I’d totally recommend this one.
