Windmill WhisperTech 8,000 BTU Smart Window Air Conditioner with Inverter Technology - White

I was very exicted when I received my unit. Installation was straight forward and the app work well. My complaint, when I run just the fan its very quiet, once i turn the “cool” setting on I hear a loud buzzing sound from the unit. Not what I was expecting, if it doesn’t level out after a week or two I’ll return it.

I’m really happy with this AC—it cools my room efficiently and quietly. The only thing it lacks is wifi connectivity for remote control. Overall, it’s a great buy!

Windmill Customer Service: ***** (5 star++) Product: * (1 star) Average the two, and we get 3 star. Ultimately I could not use this machine, and I was very hopeful since they are on Wirecutter's recommendation page. I bought a Windmill Whispertech 8000 from Best Buy to replace a 3 year old unit that was still working but on the way out. I installed it and when the pump kicks in it was very loud and vibrated. Windmill responded VERY quickly thru the chat on Saturday, and continued troubleshooting on Sunday. On Monday they confirmed they were sending out a replacement. Received the replacement, and it had basically the same problem. The offered a very generous gift card for the hassle, and sent out another replacement. Same problem! They then refunded me my ENTIRE purchase price from Best Buy on another gift card. I was still open to this machine as it was reviewed highly and it looks good and they sent out the 3rd replacement - in other words - the FOURTH machine. Same problem! Windmill customer service outdid themselves, but it still was not enough because of the problem with the machines. I can only imagine they are going thru a temporary Quality Control issue, or maybe during transit something shifts which causes the units to make lots of noise and vibrate when pump starts, how else would they get to Wirecutter's review page? But at the end of the day after all these replacements I did not receive a 'quiet' air conditioner from them - since they covered my costs it was not 'painful.' I bought another brand with similar 'quiet rating' in terms of decibels, and it worked great right out of the box.

Very good AC! Super quiet as well. Didnt give us any issues for install

I came across this AC while in search for a replacement for a wall mounted unit. This is not compatible but, and since there wasn't much options for that category I just settled for this one and decided to just install it through the window. As with most small appliances these days, unboxing was pretty easy and uneventful. And out of the box, they provide you with the usual accompaniments, but om addition, they also include a pair of scissors, just in case your household doesn't keep one, for the cardboard/plastic cutouts that serves as the cover for the side extenders. This makes for a seamless and clean look, a definite plus. After the install, which, depending on the size you purchase, may require a couple of extra hands, plug-in, and download of the app, the AC is ready for use. For our use, it is quiet but does get a bit louder as you increase the fan speed. Again, for us, it is not as loud as our other AC's and stands out as likely the quietest in our household. Our 8,000 BTU unit provides ample cooling for a small to medium sized bedroom. Depending on the time of the year, of course, and the temperature outside, you may need something larger. I like it as it functions as designed, mostly emits low noise, and can be controlled through the app. I can recommend this product to those looking for something similar.

LOVE IT….. Even in a quiet room you can barely hear it running.. The only other thing it comes with a one-year warranty. I hope it survives many years! I cosign for this brand and will purchase this brand from here on out

I love this air conditioner, very silent and great! I highly recommend it even to my arch enemies!

This dual compressor is louder than my previous ac unit, sounds like a helicopter. Looks fancy though. Little overpriced. Be aware of Buy 15 day return policy. What a waist og money. Tried Midea, much quieter, cheaper and the noice come in and out

The quietest air conditioner I have ever owned. It is amazing how quiet this is even when on full cool and full fan. We have it in our dining room just a few feet away from our dining room table and you can barely hear it. It is very easy to install because the side veins are preinstalled on the unit. If it matters to you, the Wi-Fi set up is very easy. It does feel heavier than similar capacity, air conditioners, however.
