Great AC and great Customer Service

We purchased two Windmill AC - 8K BTU WhispeTech air conditioners and love them! As a senior, the customer service team was helpful and kind in answering my questions about installation and care. The units not only look great but also are designed to be able to stay in my windows over my Vermont winter seasons eliminating the need to find others to help me remove and then reinstall the units each season.When my other older units need replacing, I intend to purchase more Windmill units!

Great and stylish little A/C

Needs to replace the window A/C in a small bedroom and I chose Windmill for the easy installation. Happy I did. We have an old house and sometimes it tricky to fit window units so I liked the thought that this one was all one piece. No accordeon sides to lose or break since they are permanently attached. The app to manage the A/C (and fan) from away was simple and effective. I will probably add another unit for a larger room at the beginning of the next summer

Super quiet and does the job!

We got an 8k BTU model which we already know is too powerful for the small 9 x 13 foot room it was put in. However, by leaving the door open the A'c does a marvelous job at cooling the room, the adjacent hallway and beyond. With simplicity of operation and it's quiet delivery of cool this A'C has my highest recommended. Now... if only they made a through the wall model!

Amazing

I did a lot of research before buying a window AC. Originally, I wanted one of the U-shaped window ACs that have been popular in recent years. When they all started being recalled over mold issues last spring, I decided to go with Windmill instead because of the inverter technology. I'm so glad I did. I have the Whispertech 8k BTU and it keeps our queen size bedroom freezing cold in the summer. It's so quiet, and it was very easy to install. I like how sleek it looks. I got a second one for our guest bedroom and in the summer when both are on and the doors are open, our entire 1200sqft apartment stays really comfortable. Electric bills were entirely reasonable and I can't say I noticed any difference from having them. 10/10.

Great machine - even better customer service

Doesn't look - or perform - like any other window unit. Stay sleek and cool with this low profile, remote-controlled unit. And the best part is the customer service team ready to help you out if any issues arise. When I had difficulty the team went above and beyond to find a creative solution. You don't get that level of attention when you're dealing with a huge company. They take pride in their products and in their service.

Fantastic quality, great look!

First AC I bought in awhile and it's a perfect buy. We moved into our first home and wanted to upgrade from our decades old ugly, loud, AC units.We bought a windmill AC which looks great, is quiet, has a great application.We loved it so much we bought an air purifier as well!

Whisper quiet, cool as the other side of the pillow

I love my Windmill AC so much, I've purchased two more (one for the home office, one for the general downstairs) to keep my house cool during the summer and quiet enough to hear one another. Easy to install (and remove in the winter) with Bluetooth capability, I can cool the house down on my ride home from the gym or the beach. 100% satisfied customer!

Looks Great, Works Well

The Windmill AC actually looks good in your space, it's easy to install, and the app control is genuinely convenient. I definitely found it useful to control from bed. Cooling-wise, it does a solid job for small to medium rooms and stays pretty quiet! I've experienced other window ACs and they were super loud in comparison. Overall, I am glad I went with this one for my small NYC apartment

Worth Every Penny

I love my Windmill AC. It was easy to install (though did take two people--its heavy) and continues to look gorgeous six months in. It has made my 100-year-old top-floor apartment livable in the summer, without sacrificing aesthetics. I love that I can turn it on from my phone when the heat picks up unexpectedly in the daytime, and know my cat won't be uncomfortable. I recommend one to everyone I know!

Bought Two Units--Love Them Both

I bought the original 6BTU unit for my bedroom and the super quiet 10BTU unit for the living room. Love the remote option. It's great that you can turn them on before you get home. They are quiet and efficient! I highly recommend them. Oh, and customer service is great.
