How It Works

NightBreeze is a smart cooling system that automatically brings in filtered outdoor air through easily installed window units.

Improve Indoor Comfort and Air Quality

In summer, NightBreeze precools your house overnight to get a “head start” on the heat. NightBreeze turns itself on and off at just the right times.

Bringing in fresh, filtered outdoor air to cool your home also improves indoor air quality for you and your family.

Stay Smart & Connected

With the NightBreeze app, you can easily input comfort preferences. Each night, NightBreeze automatically downloads the temperature forecast and uses it with your comfort preferences to determine just when to ventilate and cool your home.

Set it and forget it!

Do Good for Your Wallet and the Planet.

After your home is precooled with NightBreeze, it doesn’t need as much air conditioning the next day, saving energy and money. Depending on comfort preferences, NightBreeze can easily cut the cost of cooling your home in half!

Each NightBreeze saves up to 1 ton of carbon emissions every year!

Winter Ventilation

In winter, NightBreeze supplies fresh air for ventilation up to 10 minutes per hour. If it’s cold outside, NightBreeze won’t ventilate to prevent cold drafts.

Furnace Version

NightBreeze can also be installed in line with your furnace. This version
supplies fresh filtered air through the heating ducts to each room.
