AC for you, AC for nature

Trees are sometimes called 'nature's air conditioner' - they take in carbon dioxide from the air and help prevent our planet from overheating. But unfortunately, trees haven't been able to keep up with the world's increasing carbon emissions. To help, we're investing in tree protection projects to offset the emissions produced by every AC purchased.

From the ones living breezy

It’s so chic looking! I never wanted to show off my AC before, but my Windmill is so beautiful. My super helped me install it as I thought it was going to be hard, but it was effortless as all the parts were already assembled. My roomie and I could have just done it ourselves!”

I’m an artist, so quality design is super important to me, and this AC is absolutely gorgeous! I had one before but couldn’t stand how it looked, so I got rid of it. Now I can finally stay cool while painting, and I actually enjoy looking at it!”

Larsen M

I literally felt like I was unboxing an iPhone when I unboxed the Windmill AC. Such thoughtful packaging, design, and instruction. Installation was a breeze, my apartment feels so cool and comfortable. Anyone in the market for an AC needs this!”

Step 1 - Window type

We need to make sure your window can hold an AC unit safely. It must be a single- or double-hung window (it should slide up and down) and be in good condition. Does this describe your window?

Step 2 - Window Size

Great! Let’s figure out window size. The Windmill AC is designed to fit windows with a width of 23-37 inches and a vertical opening of at least 14 inches. Sounds accurate?
