Without being there, of course, I would also say there is a problem with the consensate line or pan. If you can’t find a reason for it, then I would defer to a heating/cooling specialist, which I’m sure you did.

There must be significant air leakage around the coil cabinet and the furnace itself. This is appears to be condensation guys not a leaky condensation line. Coil cabinets will do this when there is enough air leakage around the take offs from the plenum. On a warm humid day, the cold air will blow on the cabinet and viola, condensation, puddles, mold, and all kinds of other good stuff.Obviously a moisture problem to have a dew point that forms that kind of condensation on a cabinet. Insulating the cabinet with ductwrap will certainly help but this would need to be done during the heating season as not to trap in moisture that is already present. And if that is the bottom of the furnace, which you couldn’t wrap with duct wrap, then there is definitely an air leakage problem since cold air should never be on that side of the coil. I would also check the humidity levels of that crawl, I would guess around 70% or better with that going on.

That looks simply like condensation from the cold cabinet being installed in a damp warm environment. I find that consistently here in humid area installations (garages, crawl spaces and attics). Definitely causes the cabinets to rust out prior to the average useful life!
