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.

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?
