Took my 2013 Corolla LE, 104,000 miles in for an AC check. It's coolish, but doesn't get cold like usual, ever. The shop that I have been using for several years informed me that other than the cabin filter needing replacement, which they changed out, the system checked out. I even cleaned the condenser with PineSol/water solution 1:1 (in front of the radiator, correct?) like I do with home condenser so air flows freely.
What else can I check?
