I am having a difference of opinion with a co-worker and I am
wondering if I am right or he is right. His home AC stopped cooling
(over time) and he had it cleaned and re-charged. He said the
mechanic who charged it said it had lost nearly half its charge. I
said if it lost any of its charge, then there had to have been a
leak. To me this was common sense and agrees with what I know about
car air conditioners. He said that he would choose to agree with his
mechanic who said that all it needed was cleaning, charging and
regular (once a year) servicing.
Who's right? How else might a home air conditioner lose its charge?
If it can lose its charge without any defective parts, how does that
happen and what needs to be done to avoid that happening?
The annual cleaning is an excellent idea. Freon doesn't just disappear. if
there is less in the system, there is a leak.
Problem is, some leaks are hard to find, expensive to repair, and just
asking to be ignored. We don't know, in this case, if it's a simple leak
that's easy to fix.

You freakin moron/m,
Refrigerant DOES just disappear. Its call a leak.
Leaks are NOT hard to find if you use the right tools. You dont ignore
leaks. They are profit just like any other repair.
The only simple leak is when an idiot like you forgets to tighten the
cap or loses the O-ring seal in the end of the cap.
Now go pick up that boulder and bash your stupid head in.
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.
