Just finished recharging my A/C and now it's putting out the cold air again.
It lost it's cold so slowly over the last 8 years (it's a 2006) it seemed normal.
I did A/C 30 years ago (even certified), so I should have known better than to let it go this far.
I'll have a lot more control now, I won't have to leave it on MAX all the time.

I bought a 20 oz. can with a gauge on it. It took the whole can and still was just barely into the green for awhile. After letting it run a few minutes it dropped to just below the green area when the compressor was on. So, I added another 12 ounces and now it runs right in the middle of the green range when it cycles on. You can really tell the difference...NICE!
