Wife's car is a 2002 Toyota Corolla that is mechanically sound. The AC system works but it takes a little time to start cooling off and it does not get 'cold' per se, but it does get cool. The system has never been touched, never opened, never recharged. It's as it was from the factory.
So assuming that there are no leaks, what makes an older AC system start to lose effectiveness over time? Does the refrigerant wear out? Does the compressor not, uh... compress as well? Dirty condenser? As much as I'd love to fix this with a miracle in a can, I'm pretty sure that's not really the best way of doing so.
We have a much newer car (a 2015 Accord) that gets real cold pretty much instantly so maybe our expectations are out of whack now.
