Very pretty but loud

Much louder than expected. Looks great. I thought this one had whisper tech but it does not. Aesthetically this AC is very neat and clean and nice looking particularly for a window unit.

Bought Two A/C Units

Would Recommend

I purchased two of these as the first AC units in my new apartment. This is the first time I haven't had central AC, but these window units make it feel like I do again. They're modern, easy to operate, and keep the room cool and quiet. I have one in my bedroom and one in my living room, and I don’t see myself replacing my AC units anytime soon.

Beautiful

Would Recommend

The Windmill A/C unit is extremely attractive. The back is protected by a very beautiful grate covering the radiator fins, this is an amazing feature, especially for children, as well as for installing and winter removal. They have these sides you cut to fit perfectly over the side slides to hide, it’s just beautifully designed! An A/C unit I’ve been dreaming of.

Windmill AC

Would Recommend

It has not been hot enough to use the AC consistently.It is a little louder than I presumed it would be. This may very well be because we have old windows in our home.I do like the look of the unit. It has cooled the room down very fast on the two occasions that I have turned it on. We live in the South with high humidity, so very soon I will be using this unit consistently and will have a more thorough review.

Easy installation, beautiful product

Would Recommend

Thoroughly impressed by how easy to install the unit was. All is so well thought through that they even include the scissors for cutting the insulation pad (which is the chicest of the sort I’ve seen). The unit itself is minimalist and beautiful to look at. Very pleased overall.

I love this thing

Would Recommend

I live in the Chihuahua desert I stand by this product when it reaches 112 outside. I have one in every room of my house because I live in a historic building with no AC. And moreover I stand by this company with their amazing customer service who helped me out when I was in a pickle. They gave me stress-free troubleshooting and fast responses. The best support I’ve honestly had in years. And with no subscription go figure, other companies wish they had customer service like this.

⭐️⭐️⭐️⭐️⭐️

Would Recommend

This window AC is a total game changer. It cools the room quickly, runs quietly, and keeps a consistent, comfortable temperature even on really hot days. Installation was easy, and it feels sturdy and reliable. Definitely worth it, highly recommend!

Amazing Service

Would Recommend

The claim team is amazing and helped me greatly. The replacement unit is in place and created a quiet and cool space in our room over the garage! I could not be happier.

Amazing!

Would Recommend

I purchased two of these units last year, and I am so happy with them. I'm happy for 3 reasons. 1. They cool the room down very nicely. 2. They are quiet, very quiet. 3. They look nice in the window - sleek.I have two more rooms that use window AC's; however, the current ones still work, so I can't justify purchasing new ones. But when I do, I will head on over to the retailer that sells these amazing units. Very satisfied customer who will be returning for another purchase or two.

Awesome little window AC

Would Recommend

I got the 6000 BTU version for a teenager’s small bedroom. The unit was great. Very easy to install. Looks sleek. Having it available through the app is a nice bonus. Plan to replace older, less efficient units with other Windmill ACs this coming summer

Amazing!

Would Recommend

Excellent product and outstanding customer service! The AC does a fantastic job keeping the room cool. What truly impressed me, though, was how responsive, and helpful the support team was after I contacted them about an issue I had. They were kind, attentive, professional, and truly committed to helping/making things right. It’s refreshing to see a company that truly cares about its customers, and stands behind its products. I’m beyond satisfied, and would highly recommend them to anyone lookin...
