Service ports (schrader valves) are a somewhat common leak.
You will not "see coolant" as the cooling media (Freon) is a gas that disappears into the atmosphere. One needs a UV light to see the fluorescent dye.

Typically the most common leak (by far) is the evaporator (A/C Radiator buried inside the dashboard) itself. Most are just annoying, requiring a refill every year. Sounds like your leak is much larger than that.

I'd be curious as to what they find.

We've added R-134A stop leak into some cars with success. However those had slow leaks. (A/C would start to underperform in a month) I do not think that will fix a leak of his (presumed) size?
He has nothing to loose....

Give it a go. The hardest part is evacuating the system and then filling with the correct amount out of those stupid little cans.
Adding a charge on top of static air, will leave the system with less of an ability to cool properly in Florida summers.
