Q: WHAT ARE THE DIMENSIONS WITHOUT THE OUTSIDE PANEL WINGS AS I HAVE A VERY TIGHT SPOT SO COULD PUT IT IN IF I KNEW DIMENSIONS OF THE MACHINE ITSELF THX

Q: What is inverted and how does it work ?

submitted by Dave - 1 year ago

  • A: An inverter AC uses a variable-speed compressor instead of a simple on/off compressor. In a regular AC, the compressor turns fully on, cools the room, then shuts off, then turns back on again. That stop-start cycle uses more energy and can create bigger temperature swings. In an inverter AC, the compressor can speed up or slow down depending on how much cooling is needed. It runs harder at first to cool the room, then slows down to maintain the temperature efficiently.

    Not as quiet as I had hoped

    It’s still a window unit. It still makes noise. And because the air goes up, it doesn’t seem to cool as quickly. It sure was easy to install and it is good looking.

    Temperatures and Mode keep changing on its own with the loud beep.

    Temperature and mode changes on its own, no matter what I try, I cannot put my desired temperature, and it beeps really loud when it changes its temps or mode and disturbs my sleep.

    broke after using it 20 times

    I bought this 2 years ago. We only use it on the very hottest days, maybe 10 days in July and August. It stopped cooling. The fan works fine, but the air is hot. I following the instructions for re-setting and it did "reset" but the air is still hot. Would not recommend.

    Best A/C Unit Ever Made

    We sent back a cheaper China-made model to a box store that sold it. It simply didn't work and seemed quite flimsy. We read about Windmill being stationed in the Big Apple, was impressed by what we read, paid more, and are so thoroughly satisfied, we would recommend this unit to everyone!

    Excellent Window AC Unit

    I own two Windmill AC units and love them both! They were easy to install which is important to me. They are easy to operate and they are surprisingly quiet! Additionally, I needed to contact support for an issue and they resolved it quickly and to my satisfaction. I very much recommend their products. - JT

    Looks Great + Thoughtful Features

    Just installed my unit in my home office and it’s an immediate upgrade on my old, basic unit. Looks great, has plenty of insulation, easy setup and control, and quickly cooled down my space and held it as a consistent temp.

    Great product and customer service!

    The product works great! I ordered the extendable side panels because our windows are 38 inches, but I didn’t need them. The original panels cover the distance just fine. Their customer service was amazing!!

    A+ Service and Integrity

    Windmill was the third brand of window AC units we purchased in 18 months (portable, u-shaped), and the only one who stood by their product. Customer service was knowledgeable and diligent, and shipping quick and on-time. The window unit is sleek, installation as easy as it can get, the app easy is to use, and it cools a room within minutes. Deciding on indoor, u-shape or traditional units? Go with Windmill - their design is thoughtful, the unit efficient, and service is top-notch.

    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 window. To anyone who is in the market for a new window a/c, I would highly recommend the Windmill. We now have 2 and I will not buy anything else.

    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.

    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 life changing design for a New Yorker.

    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 replaced my unit with a new unit at no cost to me. Special thanks to Van who helped me with troubleshooting and the case review process on their end. Nice to know there are companies willing to stand by their product.

    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.
