So, I finally got my A/C recharged in my car...cold air never felt so good! They did a leak test too and there were no leaks all this time.
This goes to show that those DIY A/C rechargers at auto stores DO NOT WORK. I probably spent close to $50 trying to fill it myself...do yourself a favor if your A/C runs out - go get it done by the shop. It cost me $80 and a couple of hours.
...just in time for Laramie's cold weather, eh?
