Is There Any Other Way to Exhaust the Air From an Evaporative Cooler Instead of Leaving Doors or Windows Open?
You have the option to install a ceiling vent to exhaust the air out of your space or home. This will also aid in reducing the heat in your attic, but it is important to provide adequate exhaust in the attic as well. Every 1,000 cfm of air delivery requires 2 square feet of relief. Note that ceiling vents do not provide adequate relief air in peak hot season.
