Looking for a window fan that can blow in cool air at night and seal up reasonably well during the day when it's hot and I use the AC. Any advice? Yes I've searched the internet but I've gotten ambiguous results. PS: this needs to be installable on a slider window.
@Huesmann is correct in that I am looking for a fan that seals up reasonably tight when not in use. It's typically 90-110F in the summer, but we get cool nights (<55F). So I'd love to pump cold air in at night, but have it sealed tight during the heat of the day. I am not finding anything commercially, especially that works for horizontally sliding windows. I did find an "Air King" window fan that allows the window to close behind it (ideal!!), but it is unclear whether the install would work for slider windows.
