Apartment complex reduces to fix a/c. What can I do?

[Steve S.]

They’ve been out 6 times. A/c runs all night and at around midnight gets to 77 degrees. It’s an 800 sq ft apartment so shouldn’t take long at all to cool off

They are clearly trying to run out the clock on summer. 

I’ve had it. Can I get out of my lease?  I have 6 more months. 

What authority can I report them to?  I need some action and they refuse to address it. They just come out and clean off the coils allegedly. That does nothing.
