This window unit from TOSOT's "tranquility series" can easily cool a 350-square-foot space without making the entire room noisy. This AC features a modern front panel design, a sound level of just 42 decibels, is Energy Star rated, comes with a remote, and has adjustable wind louvers if you find the cold air is blowing in your face too much.

Promising review: "Lots of reviews here refer to the Chalet model. I purchased the Tranquility: it is really much more silent than any other window unit I have ever seen/owned. Of course, it is not silent, it is much quieter. I'm not sure that it is as quiet as a library as they say in the description, but definitely you can work and talk or listen to TV while this unit is cooling your space. The design is nice too." – Dada

Promising review: “I live in an old house that gets hot and humid very quickly in summer. I've tried so many other window units, and this is by far the best! It looks great (both from the inside and outside view) and was super easy to install. It cools down my place quickly and quietly - I have it in the window in my living room, and it easily cools the entire common space: living room, side room, dining room, and hall. The best part is how quiet it is! I can sit on the couch essentially directly next to it and still be able to hear the tv or have a chat with friends. Honestly, the first time I plugged it in and turned it on, I thought it was broken because I could barely hear it, but it turned out it's just *that* quiet, especially compared to other units I've used. I love the bluetooth functionality as well. I can go on the app when I get out of work, turn on the AC remotely, and by the time I get home, it's nice and cool. Other reviews have mentioned the internal thermometer is off by a few degrees, and while this is true, it hasn't had any impact on the unit working for me. If you're on the fence, I absolutely recommend this product!” — Rachael M

"After buying and returning several air conditioning units, reading thousands of reviews, and roasting at night I finally found my perfect match. This unit is SO QUIET," one Amazon reviewer wrote. "I have a very low tolerance for humming noises and this one I barely notice. It blows wonderfully cold air, was easy to install and I love that you can program it to turn on and off at a certain time each day. My bedroom is finally cool enough and quiet enough I can sleep peacefully."
