I'm having a huge heat problem. Room gets up to 96 today. I open the door every hour to air out so it can drop to atleast 85 deg. I added an air vent which was 3inch with a small fan pulling air out of crawl space and a vent to let air out to crawl space with a bath room fan.

Do i make bigger holes and try to push and pull more air?

Or should i try to get a A/c which is $ but need on for the bedroom any ways?

Crawl space is always cool never gets hot down there.
