Good point. That may be why the OP's vent temperatures are a little different than mine when I had a similar problem.
I was surprised when it turned out I needed refrigerant, especially since we had checked the pressures a few months earlier, in the spring. I used to have to add most of a 7 oz R-134a can every two or three years. Now, I add some every year. I just finished off my original 20 oz can of AC Pro, so I've probably only been using it for three years. I'm going to switch to the high mileage version going forward. It has more leak sealant. They don't seem to sell the high mileage version with the charging hose, at least at Walmart.
