I had this problem living in Dallas: it'll hit 108°F just about every day this week.

I also couldn't spend thousands on an energy recovery ventilator (ERV) installation because I've been living in rental properties.

My solution was to buy an ERV for ~$500 and rig it up to an open window: https://gen.co/air

I've since moved into a condo with a bedroom with no windows and french glass doors so I installed a cat door and mounted the ERV vents to that.

I think there's a lot of money here for someone to build an ERV designed to be window mounted.
