Windmill Window Air Conditioner - Quiet & Smart, Easy Install, Voice-Enabled, Remote & App Control AC Unit - 6,000 BTU

Great packaging, loved that it had heavy-duty strap, making it easy to get to window. Installation instructions perfect (great installation video). So easy to install, no bracket needed. It’s quiet, no rattling, just a gentle hum. My old a/c had a louver that vibrated. Windmill has none. The double-sided insulation snaps into place, looks good & keeps out street noise. Love the app. I’ll probably never use the remote. Not a fan of the “eco” mode (I wasn’t with my old a/c either). Low fan on cool keeps room at consistent, comfortable temperature. Highly recommend!

Love this AC. Easy to install. Much quieter than other ACs I've had. It keeps my room cool and energy efficient. (I've kept it in Eco mode and it still stays cool.) Next generation AC. If I find some extra money soon, I'd like to add one to my bedroom so I can sleep more easily. So glad I took the chance and tried this. You won't be disappointed

Best bang for the buck AC unit hands down! We have two 6k units (one in each bedroom). Lightweight & easy setup. Wifi & remote. Super clean look inside & out. Very efficient & easy maintenance.

All windows AC, regardless of brand, perform one function; cool down a space/room. For this review, I am putting installation and operations aside. I am only focusing on the most important aspect to me, the noise level. Based upon the many positive reviews, I purchased a Windmill Air Conditioner Smart Home AC Unit 6000 BTU for a small home office (12ft x10ft). The test setup: Sound measuring device = Samsung Galaxy S6 & Sound Meter app by Abc Apps. Table setup at 8ft directly in front and at the same height as AC. Thermometer = DIGI-SENSE Traceable Wall-Mount Digital Clock/Calendar x2 I began the test by making the room as quest as possible. Everything was shutdown, windows and doors closed and all outside noise within my control were also turned OFF. I measured the room noise level, then set the AC unit to Cool, Fan Low, Fan Medium and Fan High. Results are: OFF (room dB) = 21 Fan Low dB = 49 Fan Med dB = 51 Fan Hi dB = 53 I was surprised and somewhat disappointed to say the least. This was loud. From all the reviews, I thought the noise level should be lower. Windmill Air advertised this to be quiet. It’s louder than my 15 yr. old Whirlpool. Definitely very loud for sleeping. It’s in the office, but I will have to shut it down for virtual meetings or calls. Another note: The temperature gauge is consistently off by about 8-10 degrees. Its reading 63 degrees while the room thermometer is reading 73. This is occurring all the time. The unit shuts down while the room is still warm. My room thermometers are Digi Sense 08610-26 Traceable Wall-Mount Digital Clock/Calendar NIST which are calibrated and compliant for ISO, FDA, and cGMP manufacturing environments. I’m fairly confident that the Windmill Air AC’s temperature control is in-accurate. I have two different brand AC units in the bedrooms which I will put into the same test. More to come…. UPDATE: I have to give a shout out to Windmill Air's customer service. They were very supportive and we went over several debug methods. 5 stars to customer service. The rattling noise was still there after debugging and in the end, they sent me a replacement unit. I put it through the same test as described above. While the rattling noise was gone with the new AC, the noise level itself was not as quiet as expected. The decibels were still the same. I did a comparison with my other two ACs: Midea 8000 BTU U-Shaped and a 15 yr Whirlpool ~1800 BTU. The results are: OFF (room dB) Fan Low dB Fan Med dB Fan Hi dB Windmill Air 6000 BTU 21 49 51 53 Midea 8000 BTU U-Shaped 21 32 35 41 Whirlpool 21 42 49 49 The Midea was truly quiet coming in at 32dBs on low fan setting. Perfect for a bedroom. The Windmill Air is ideally a small office AC and the noise level is acceptable for that purpose. I have upgraded my review to 3 stars for the level of customer service.

I have a very limited space on a 3rd floor apartment in an ancient house - so summers get hot. Unfortunately, there's really only one space for my dog's bed to go, and for the past few summers she's had to compete with the AC hanging loudly over her bed. Not so with the Windmill. It sits much shallower in the window, though the extra screw points leave it more secure than my past unit. It's sleek (which I like) and quiet (which she likes) and voila - I don't have a hot dog in my bed, she doesn't have a loud AC in hers, and everyone in the house is much happier. Even before the app, it's a superior option to standard units (and for folks who are app averse, you honestly don't even need it). Once you factor in the technology and sleek design, it fits in really nicely to the space (and yes, it does the job too - nice and cool). Life saver for me!
