Secondarily, should the fan be outside or inside the window?
Asking for a friend. (Me, help. I can’t remember physics, it’s too goddamn hot)
Edit: I’ve opened all the windows and set up a fan a short distance from the window pointing out and it’s reduced the temperature to near-tolerable levels. Unfortunately, venting through the attic was a no-go but moving things aside might make it an option next time. Thank you all, I appreciate the help!
I wouldn’t point all my fans in or out unless they’re all on one side of the building. You want to create a ‘wind tunnel’ effect to pull the air through the house and this is best achieved by keeping all the air flowing in one direction (north to south, east to west, etc).
Using the HVAC fan definitely helps a ton. Our vents are all below windows and this really causes the air to get moving.
