Repair Rusted Attic AC Condensate Pan??
I've got a central AC unit in my attic, and the main coil condensate pan is rusted through, to the point where the condensate is leaking into the "backup" pan. Last year, I attempted to fix the pan with an epoxy material, which worked for a short while, but now the pan is leaking again, and the drain is still clear.
My guess is the way to properly fix the pan is to have a tech come out and perhaps replace the coil. My problem with this is that the AC is already 14 years old, so I'm thinking that it doesn't have too much life left, and it's working fine, except for the condensate leak. So, I hate to spend that much money on an older unit.
I've been thinking that as an alternative, I can fashion a pan to install between the coil cabinet (horizontal unit installation about a foot off the floor of the attic) and the backup pan, and pipe this "new" pan into the primary condensate drain. So, I'd effectively catch the leaking condensate before it comes in contact with the backup pan/drain.
Does this approach make sense, or am I better off spending quite a bit of money to have this properly fixed? Again, my main concern is that this is an older unit, and I'm thinking I'm better off saving my money for eventual replacement. Am I missing something with this thinking?
Thanks, in advance, for your advice!
