Thanks..

Well.. the tech is working for a company that is certified. and so on..
But as to his reliability, I guess only time will tell.. unfortunately..

I didn't know that freeon had an odor.. I thought it was one of those
odorless gases..

Regarding whether the detector was working properly, the tech did
complain about the batteries, and so I replaced them with 2 new ones of
my one, that I just bought the day before, and it still have the same
results..

Thanks

That's a pretty well written description. IFF the tech was
reliable, then you have a leak in the walls, it seems funny he
wasn't able to detect it anywhere. If it's leaking into the
walls, there has to be an exit point for it and it'll be
detectable there.

If it's actually "freon" as you said, that has a pretty good odor
and at the loss rate you indicate, you should be able to smell it
yoruself, even.

How does he/you know, if the detector was functioning and being
used, correctly?

Also, if this is in the attic, I don't know why a hole would have
to be made in a wall. It should be pretty easy to pull out the
old and fish in a new pipe. IMO at least; no expert here, just
an avid diy'er.

Just my two cents; I know it isn't my money, but if I were you I
think I'd try another service and if they came up with the same
results, consider replacing what needs to be done. It's still
cheaper than paying housecalls for freon every two weeks in your
climate.
