You are... your co-worker and his *so-called* tech are complete dumbasses.

Thank you. Guess I'll let him feel superior for a while.

Real simple to figure out.... Have the tech do an electronic leak search.
When the electronic sniffer finds a leak that big, it will go crazy even
being in the same room as the leak. Its a "sealed" system and unless there
is a leak, then it should *NEVER* lose any of its refrigerant charge. The
system should be checked at least yearly to make sure that it has not
developed any leaks. At this point in time, assuming that it is an R-22
system, your co-worker would be money ahead to replace the entire system
with a new super energy efficient R-410a system. If your co-worker suspects
someone stealing the refrigerant or "huffing" the refrigerant, put a dot of
fingernail polish on the caps to create a seal that will be a tattletail to
see if somebody is opening up the system that isn't authorized. If you think
its a neighborhood kid, then also coat the caps with Prussian Blue....and
when the seal is found to be broken, look for the kid with the blue fingers.

Hell with that. Get an ammonia based system :-)
