Ratings & Reviews for Windmill Large Room Window Air Conditioner , Remote Included ( 115-Volt , 12000-BTU ) ENERGY STAR Certified

The future of window a/c’s

These Windmill air conditioners set a new standard for the window a/c market. From the non invasive, sleek design and quiet efficient operation, to the second to none customer service and care, they are what all window air conditioners should be from here on out. They don’t cost much more than the old noisy, uneven air, obnoxious ones do either, and with their deals and discounts they are pretty much the same, but you get a much better quality unit, that truly looks good hanging out of your wind...

Excellent product

I am very happy with my new unit. I purchased it mostly because I was impressed with the design, and i wasn't wrong. This is how ac units should be made.

Love!

Vaulted ceilings and I was skeptical...but it kept my house an amazing 69° during the last heatwave. 12k BTU version. Simple to install. It's pretty quiet, too, which is great for being on work video calls. Love it.

Good customer service

Easy to install, very user friendly. Easy to set up app. Unfortunately my unit was one that started making a loud motor noise, which you might see in some other reviews. However they have really good customer service. After sending a few videos they sent me a replacement! Francesca and Rachel and others were very responsive and nice. The new unit is nice and quiet. Make sure you register your unit!

Quiet gem

As promised, easy to install and quiet. However, the 8,000 BTU Whisper Tech model is large and heavier than I expected.

Very 😥 Disappointed

I am very disappointed in the product. If I would of known that there was no water plug to allow water to drip out I would not of bought it. I had to look up on Google what to do with the water that was backing up and was instructed to take it out of the window and tip it backwards, really??? After screwing the A/C to the window what a absolute inconvenience. I would of given 5 star review if it wasn't for this. Who makes a product like this knowing the water has to go somewhere 🤔 very disappo...

5 stars

I am so happy with this tiny sleek mighty window unit. After a day of running it felt like I had central air. It’s fabulous. Keeps the whole apartment/ room cool and the air rises so it really feels like central air. It’s sleek and really attractive and very minimalist. I replaced my old ac unit and it is quite the upgrade. Love all the panels too makes it sealed and attractive. Very pleasing to the eye. Keeps you cool. Love being able to control it with my phone. So awesome. Thank you. Truly li...

Like the design but too noisy

While I fell for the sleek design, I have to say that it keeps me up all night due to the noise level. Sadly there is no low . Cools the room well enough.

Stood by your product!

I purchased a Windmill AC in June of 2025. I used it during the summer of 2025 and put it away in the fall. When I pulled the unit out for this summer I noticed that not long after installing it the unit was not blowing cold air. I contacted Windmill and was worried that since it had been slightly over a year since I had purchased it (like many companies) I would hear that my year warranty had expired and there was nothing they could do. To the credit of Windmill, they stood by their product and...

Outstanding Customer Service

I am very pleased with this window AC unit. It is very quiet and looks great. The magnetic cover on the front is a great design making it so easy to takeoff and clean the air filter. The windmill app is simple and straightforward, making it easy to use as well. The only problem I had was with the included remote control not working. I contacted customer service and had a reply from Rachel within 10 minutes! She suggested a simple fix, which did not work and so she had a new remote sent out to me...

Confusing instructions

Some of the instructions were a bit confusing. When I went to use the QR code for a video explanation it was a dead link.

Windmill

We love our windmill AC’s. We have a small one in each bedroom and they are great and very quiet. Customer service is wonderful too. We had an issue and they were quick to respond help us out.

Great Customer Service

We had an issue with a new unit and got a replacement within a week of initiating contact - new unit was delivered in time for a big heat wave where we live in Southwest Colorado. We had an easy time setting up the unit and love the Wi-Fi interface. I highly recommend Windmill!

The only window AC unit you will ever want

I purchased 3 of these units to cool my home. They arrived well packed, installation was a breeze, and they run quietly and efficiently to keep my home cool.The ability to operate them using the app is a big plus !

Excellence!

This unit is attractive, quiet, easy to install and use. The phone app makes it easy to turn the air on before I get home! This is an outstanding company for product as well as customer service. They deliver what they promise and what they guarantee! I'll never buy another brand again!

Great AC, Even Better Customer Support

We've been using the Windmill AC in our kids' room and overall really like the design and quiet operation. After about a year of use, our unit started glitching and beeping intermittently. I reached out to Windmill's support team, and even though we were technically just past the standard warranty window, they went above and beyond to make it right and approved a replacement unit for us. The process was smooth, communication was clear, and the team was genuinely helpful and responsive every step...

Owner

Best company that really cares about their customers. They respond immediately when you email them. I had an issue with a new Windmill ac, and it was taken care of within 2 weeks. Thank you Windmill company how fast and professional you helped me. Best customers service ever,Lloyd Weatherford
