you should reverse the door hinges so it swings outward

Can fun pulling air into attic, hook up heppa filter to window for cool air intake. Negative pressure will be replaced with cool air, while your exhaust sucks hot air out. U can also spend $70 on a thermostat control that will turn on when temos reach a set temperature. This will allow your fan to automatically ventthe room when temps exceed the set temp.
