When you think about cooling a home, it’s not intuitive to consider opening windows, but in the case of an evaporative cooler it’s actually recommended.

Here’s Why: An evaporative cooler works by blowing cooled air into a home. Since air is being blown in at such a high rate, usually 3000+ cubic feet of air per minute, all of that air needs somewhere to go. By opening windows or doors, the air will have a place to travel and continue to circulate throughout the home. Opening certain windows is also a way to control the flow of the cooled air to maximize comfort in certain desired areas of the house.
