    A whole batch of comments here on why the thing is wet. Who cares if it's wet? Sure blow back, bad drains and all types of thing can cause that. It's a coil! It gets wet. Plain almost distilled water is not going to cause galvanized metal to rot out that fast! Look at the way that copper piping is discolored as well. This is just not the normal patina copper takes on in time.

    There is something in the airstream (probably from the home itself) that is reacting with that water and turning it corrosive. I think of a few beauty shops I worked on years back when hair sprays had propellants that would rot the hell out of steel heat exchangers using inside air for combustion.

    Even the worst pos galvanizing job on that coil would not account for the way that copper looks.

    Home owner may have sprayed it with a home made remedy and didn't rinse it

    Funny man!

    But, no, it's a Carrier coil; I can tell by the way it's designed.
    WHY?

    That is a Lennox coil. Not cheap. Carrier has a colder inlet & flare outlet on their txv. Goodman uses the same txv, but it is adjustable, that one has fixed superheat.

    He should just cut his losses, sell it as a "NEW" goodman and buy another coil! I'm so funny!

    Should have said Carrier has a SOLDER inlet, not colder. OOPS.

    first...
    why does the house have high humidity?

    there is a lot of rust and copper oxide, is the system oversized? what are the system pressures? temps? what is feeding the airstream? gas furnace? how's the flue?
    The TRUE highest cost system is the system not installed properly...
