About Us


We grew up in the northeast before the “miracle” of air conditioning reached New York.  At night we opened the windows, put in the fans and in the morning we reversed the process. Some nights it was warm when we went to bed but by morning it was always comfortable.   It was just what everyone did in the summer.

Now we live in the age of air conditioning, where almost 90% of our homes have adopted A/C as the preferred way to keep us cool; although some people still use window fans, most people just seal up the house,  turn on the air conditioner and wait for fall. It’s so convenient that most of us could not imagine living without it, but most people have no idea how expensive air conditioning really is or how bad it is for the environment.  In the United States it’s the #1 category of residential electricity consumption. And it’s also the #1 source of residential green house gases generating over 100 million tons of carbon dioxide that are released into the atmosphere every year.    

In 2010 we started on a journey to find more affordable and more environmentally friendly way to keep our homes cool, while maintaining the convenience we are all so used to.   We quickly found that we could not totally eliminate air conditioning; it’s still needed for the hot, humid weather in many parts of the country. We decided to investigate the potential of going back in time and use nature’s cool air.  What we found is that in every part of North America we could take advantage of the seasonal and daily temperature variations to dramatically reduce the need for air conditioning.

Our solution is a unit that is easily installed in windows, seals up so it can be left there year round, and is smart enough to let cool, filtered outdoor air in when it makes sense and automatically switches to air conditioning during hot, humid weather.  

Using nature’s free cool air is the ultimate sustainable solution that can reduce the need for air conditioning from 30% in the southeast to 90% in the mild climates.  Plus it’s good for you. Fresh air not only feels good but is also good for your health! We hope you will adopt nature’s cooling to reduce your utility bill and help reduce global warming.
