Talking about leaking indoor coils... who is installing these coils?
(you or an employee)

I ask, because it can be caused by not pulling an adequite vacuum.
Or, enviromental issues... new homes that are tight and ending up with
"formicary corrosion".
One thing that ICP has done to combat formicary corrosion is to tin coat
their hair pins. This has cut down on the enviromental effects on the coils
tremendously.

I usually do the start-ups, pull the vacuum etc., but as far as I'm
concerned "formicary corrosion" is a phrase made up to mask
the real meaning which is "coil made like crap". We've been using the
same installation techniques,refrigerant (R-22) & oil for a lot of years
without hearing about "formicary corrosion". Now in recent years coils are
leaking at a ridiculous rate because of formicary corrosion. I'm not
saying it doesn't exist, so does rust, but if a coil is made strong
or thick enough it will outlast a compressor. The copper tubing in todays
coils is probably half the thickness of those made thirty years ago. That
coupled with the fact that workmanship has become a joke in our society
gives rise to "formicary corrosion".

Most all of the premature coil failures that I run across are because there
was never a proper trap put in the drain line. 99.9% of all evap coil
failures were on air handlers the other on was with a gas furnace.

If that's so then it only proves my theory of how poor the coils are being
made. Just think of it, a coil failing because of an excess mixture
of air & moisture from improper drain trapping. I tell my customers all the
time not to expect the same life out of the new unit that they got out of
their old one. Hell you're lucky to get a capacitor to last five years
today & the manufacturers blame it on the heat. Like it just started
getting hot in the twenty first century.
