New Rheem Contour/AC unit, matched coil. Arzel-zoning with bypass. Works great, but with several humid 95 degree days in a row it started to get small amounts of water leaking out as shown - I checked and nothing is leaking from above, and the condensate drain doesn't appear clogged. There are no leaks on our more usual 80-85 degree days. Should I be concerned? Doesn't seem right it should leak, ever, but the conditions under which it does are so unusual for here that I can tolerate it if need be. I'm guessing it's related to icing of the coil which is worsened by the bypass damper recirculating already-cooled air (zones are relatively small). Note: I did check the line piping and entry to the unit and it was not sweating or dripping.
I know I should contact the dealer, but I'd expect "it looks fine to us now, can't figure it out unless it does it again" - of course it will only do it again during an unusual heat wave and they'll then be so busy they can't get out while the problem is there!
