How do AirScape whole house fans work?

The ins and outs of ventilation cooling—in under a minute

As soon as the evening cools off, your AirScape can come on. It's designed to quietly run all night, steadily drawing cool fresh air in through open windows while exhausting hot stale air out through attic roof vents. This creates a cool, fresh, natural living and sleeping environment while drawing heat out of the structure to reduce A/C load for the next day.
