My A coil has two drains.
The primary is about 1/2 below the safety.
The primary is trapped and plumbed to a safe drain (in my case the
condensate pump for my furnace).
The secondary is left wide open, if you ever see water there the main
drain is plugged.

Check to make sure you don't have a leak in the delivery side blowing on the
return duct, as a cold wall on the return will cause condensation on the inside.
Only thing I can think of other than a plumbing leak upstairs that is somehow
making it's way into the return.
Just had another thought,
Agreed, if it's condensation it has to be coming from the cold air side somhow.
I've never seen condensation on the return air side, no matter how humid it is,
and I don't think it's possible. That's room-temperature air coming back to be

When the AC is in operation, on my AC, the cold A coil in the air handler
will produce a lot of condensate dripping from it, as the warm air hits the
cold coils. There is a pan below the coil, which has a drain outside the
house.
Perhaps your drain is plugged, so the water has found another

My house has a basic HVAC system. We have a gas fired furnace in the
basement and central air installed with the furnace. The evaporator A
coil sits in the warm air plenum above the furnace. The Condenser sits
outside by the back door. The whole setup of furnace and air conditioner
is Lennox
