Some places if you paid rent for a place with AC she has to provide a working one. You can report landlords here for that BS. I would inform her I'm taking the $ per day off next months rent as I cannot live in that oven without AC. I do AC work for a living and I know a trailer is an oven without AC.

BTW I spent several hours working in an attic yesterday as part of my fun filled 14 hour day. Heat and I are close friends.
