I have a 3 year old Trane XL14i. The evaporater coil / air handler is
in the attic here in south Florida (fairly common). Now that it is
cooler, I opened it up to clean the blower and just inspect
everything. I removed the side panel to the air handler and the
galvanized triangular panel on the A-coil. The bottom half of the A-
coil sides are full of rust.
Anyway, the parts have a 10 year warranty, but labor was only 2
years. I fear the entire A-coil is going o rust away within a few
years. Should I get it replaced now or wait until there is a cooling
problem? Is there anyway I can stop the rust? I know enough about
corrosion to know my "fix" could make things worse (ie., the copper
coils could start to corrode instead of the steel).
Thanks in advance.

Actually, your best bet would to be to call your Trane dealer, or
another if you like and purchase a 10 yr Parts AND Labor warranty
through Trane. Then when it goes bad (and something WILL go bad) you
get it fixed totally free.
Unfortunately it's normal for them to rust. If it's any consolation I've
seen them rusting for years without much consequence. I suspect they are
engineered with enough material so that they remain structurally sound.
You might check to be sure the water is not standing during the "off cycle."
If water is allowed to stand to long, it will [over time] rust through.
Although the drain pan(s) may be of 16 / 14 gauge, and have a long life with
water standing in them, you will benefit greatly by insuring ALL of the
condensate drains off during the off cycle.
YES, water is standing in the pan when the unit is off. I was there
for the install and asked about the fact that the drain hole was a bit
above the bottom of the drain pan and I was told that was to keep
debris (rust flakes, dust, etc.) from clogging the line as it would
drop to the bottom. The only easy way I can see to get more water to
drain is to tilt the unit a few degrees. It is hanging from 4 chains,
so I can raise 2 a bit without breaking any seals around the ducts (I
think). However, I don't think I'd be able to get all the water out.

Don't fear that is what it supose to do, how do you expect them
to sale you new one.
