Did a quick search. Actually, the
annual leakage rate, according to this EPA study, is
10.7% That's worse than I originally thought.
The rubber hose is one primary villain here. It's a good read.
Mobile (automotive)
Average annual leakage
10.5% (A.D. Little)
9.2% (Baker)
6.9% (Schwartz)
18.5% (Petitjean)
8.6% (Petitjean)
Average = 10.7%

When someone asks where the valve is to add refrigerant, I worry that perhaps he hasn't received his certificate yet.
