Summer means a whole lot of fun, but it also means a whole lot of heat. Luckily, we have time to prepare before the dog days of summer really hit. If your window ac unit barely got your through last summer, now’s the time to replace it. Ahead of Prime Day, there are plenty of sales on solid window units, but the one you should take advantage of is on the GE Profile ClearView AC.

We test portable, ductless, and window ac units and nitpick features, installation, and ease of use. Keeping all that in mind, the GE Profile Clear View performs the best overall when it comes to window units. It’s easy to install, cools a room fast, and operates easily and quietly.

The GE Profile ClearView works as other do, by pulling in warm and humid air, cooling and drying it, and sending it back into the room while pushing heat outside. However, it differs by sitting on your windowsill and taking up just a few inches of space, instead of blocking your entire view. That also means you can still open your window for a cool summer breeze at night, or to air out your apt.

The digital display is simple and easy to control, though you can also opt for the app which is quite intuitive. It’s also a plus that you can set you AC to run before you arrive home in order to cool down your room. The U-Shape not only give you a clear view, but also some peace of mind: there’s no outdoor bracket to fuss with and you don;t have to worry about it falling out of your window—a big bonus if you’re installing by yourself and don’t trust your handyman skills (it’s ok, I question mine too).
