how much does it cost for ac fix, DIY possible? and massive shoutouts

Couple things,

My ac system may have a not so slow leak in it. Steve keith came over after my first battery issues last year to fix that as well as my ac. we topped it off but it only lasted a few days. My non professional diagnosis says there is a leak somewhere.

any advice on how to fix? What tools do i need?

Credit where it is due, during my latest battery hassles, Steve Keith did an awesome job of keeping me sane and helping me avoid a Darwin award for bridging battery terminals.

Also massive props to TMR-JWAP for incredibly fast shipping, reliable service and knowing a crap ton about the modules he sells.

Summer is coming and driving a hot prius is no fun.
