It must run in the family. Back in the 60s, Grandpa Tony started a small AC business in NYC with his son, George. That business is now in its third generation and services some of the largest buildings in the country.
We started Windmill to help you feel more comfortable at home
A lot’s changed since the Grandpa Tony days, but as a whole, window AC units haven’t gotten much of an upgrade. They’re still clunky, and finding the right one is still a pain. Staying comfortable shouldn’t be so... uncomfortable.
Combining a fresh, young perspective with 60 years of AC expertise, we started a new company and built a quality unit with today’s needs in mind.
We think Grandpa Tony would be proud.

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.
