Purchased a 6000 btu unit for a small home office. Easy setup and nicely designed. Was having trouble with unit cooling properly and emailed customer service. We went through some troubleshooting steps and determined the unit was defective. They sent a replacement that I received 2 days later. No jumping through hoops . Amazing. Thank you Windmill. You have made a lifelong customer.

Not entirely impressed. My room is roughly 300sq feet and I feel as if my 8300bcu unit has to run for entirely too long for it to cool the room down. Eco mode is not the move either, takes twice as long and doesn't keep the room cooled like when it's on "cool" mode.

This AC unit is SO pretty and it completely cools the room within minutes. The set up was extremely easy and stream lined. I love the way it looks, and I love that they thought to make simple covers for the accordion parts on the unit. I love that it's controlled by an app too. 10/10 I've recommended this unit to everyone who will listen!

The Windmill a/c is great- it's quite elegant looking and cools very well. It is overall much more quiet than a regular a/c but does still have a bit of a vibration sound even with the whisper tech; I had returned the initial unit because I didn't think it was supposed to make that sound, but the second one also makes that sound, so it's just the way it is but it's still really great.

You often find products these days that are upgrades of common things we know and love but are brilliant with their beautiful design and marketing and as a designer I'm a sucker for all of it so the Windmill ads caught my eye. Ultimately, I was intrigued by the selling points so we finally decided to get one and I was really hoping it would be the real deal. And it is, that's why we got another one! We love how sleek our Windmills look, how quiet they are, and how cooling they are. In fact the one in our living room also cools the hallway and kitchen that are connected via separate open doorways which is extremely impressive. Windmill helped us get professional installers, for our first unit in the living room, because we live on a busy street and needed to have a safety bracket installed. The professional installation was far from cheap but an A+ experience. We thought about doing a pro installation for the second AC unit in the bedroom but we decided not to because we didn't love that it would take away our choice to remove it in the off months. 99% chance we'll leave it in but we liked the idea of having the removal option since that room only has one window so doesn't otherwise have great ventilation and I love a good natural breeze. I was nervous about installing it ourselves but it was as easy as any other AC I've had if not easier given the well designed simple instructions. I don't normally write reviews but have been so impressed with the Windmill ACs we got this season and thought this info might be helpful for you if you're considering it. I highly recommend. Thanks Windmill!

We are pleased with the performance of the Windmill so far. It arrived at the perfect time- the first week of August 2022 as the heat wave was building back up in the North East. It is a much quieter air conditioner than any we have ever owned. Much needed!

I love our windmill! The design is so great. It shoots air stright up instead of out so it cools the room efficiently from the top down. I love being able to control it from the app and set automations for it to turn on and off. Our old unit used to leak on my neighbor's patio like crazy, and that hasn't been a problem so far, therefore saving us the annual strife of jerry-rigging some kind of drainage to a bulky AC.

I can’t say enough about my new Windmill Whispertech AC unit. First, for a window unit, it’s incredibly quiet! But also, ordering and shipping were easy and efficient. I really appreciate good customer service, and Windmill’s has been top notch. Additionally, I’m very happy with the ease of installation and the app is quite useful. I never thought I’d say this because it’s an AC, but it actually looks great! It’s very aesthetic and looks good in my living room. If you are looking for an efficient, quiet, good looking air conditioner, Windmill is the way to go. Worth every bit of the price.

An excellent design and so, so quiet. I got the 8000 btu WhisperTech model. It looks so nice in my studio and I was surprised at how powerful it was. I love automating it to turn on an hour before I get home from work to walk in to a perfectly cool home.

The Windmill team was amazing to work with. I received my AC and noticed it was making a buzzing noise. After some troubleshooting with the Windmill team, they offered to send me a new one to ensure I was fully satisfied. All interactions were extremely attentive and helpful. The window unit now works nicely as well!
