Any A/C Guys on here?

It's the bottom of the Air Handler unit that is sweating... but only 1 of the 2 units is sweating... seems if it was humidity or air flow in the attic that both units would be affected. There is a float switch in the drip pans to kill the unit if the water doesn't drain... It's just draining out the overflow but it shouldn't be sweating that bad right?

if its electric heat then that is where the coil is located and its only got like 1/2" of thin insulation between the coil and the metal casing so it gets cool to the touch normally but if the coil is dirty or developing ice it gets very cold and the outside casing of the unit will get cold enough to sweat just like your beer can does. under normal conditions the attic heat warms it enough so it doesn't sweat
