My home office used to be too hot for comfort, but now it's refreshingly breezy thanks to a well-placed portable air conditioner. With Prime Day deals rolling in 2026, I found some excellent options that can make any awkwardly placed window or room cooler and more bearable.

WIRED's top picks include the Dreo 740S portable AC, which dropped my office temperature by 20 degrees in just minutes. It’s a powerful 16,000 BTU unit that can be controlled via remote or app, making it easy to manage from anywhere.

The Midea U-Shaped air conditioner is another standout choice for window installation. Not only does it remain nearly 20 percent off during Prime Day, but its unique shape allows you to open the window on cool nights without worrying about de-installing the unit first. The difference in soundproofing between this and my old Frigidaire is like night and day.

For those looking for a more traditional setup, the Windmill 8,000 BTU model is both easy to install and surprisingly unobtrusive. Former WIRED reviewer Adrienne So praised it highly, calling it her first air conditioner that she didn’t want to bash out of the window.

Whether you’re dealing with a cranny or a corner, these deals offer practical solutions for keeping your space cool. With options like these, there’s no reason to sweat this summer.
