Thanks Stormin for the effort! Really appreciate it!


I learned about the damper from the thread. Didn't know I had one and
don't shut it off. Have to do that next summer.

I don't measure humidity but Aprilaire seems to work OK but things do
dry out in the winter. I put in a new pad every year as old has a lot
of salts precipitated around it although I think it could work for a
couple of years without change.

Leaving the damper open with central AC makes
it much more likely to freeze the evaporator
coil.

I'm wondering if the OP need to replace that pad,
might be the water is on the outside of the pad,
not soaking into the fibers.

Thanks Stormin for the thinking, I actually bought a new pad on Friday and put it in already, I had the side with the black mark facing up. Although it seemed to me that the side facing into the return duct also matters, I had the pad oriented so that the little holes in it go upwards, not sure if it's correct though.
