We are deeply honored by your deletion. It makes our day to know that
our Security team has done such an excellent job of repelling riffraff.

Do a CAT scan to check for piss on the unit.

It is a case of disimilar metals and on the coast with electrolyte
like salt the fins rot away. There are other electrolytes besides salt
so maybe take a look at what kind of industry is up wind.

Now other causes I have seen, and this happened on a copper tube -
copper fin coil was from electromagetism, roof top units and their
close proximity to mutilple overhead power services.

If the units are on the ground then it is also the case of good old
fashioned dog piss
