Dripping HVAC Expansion Coil Case

The case around my "A" Coil drips like crazy when the outside temp is in the +90s and Heat Index is in the 100s. I have a 12 year old 4 ton outside 9.5 SEER condensing unit and an five year old air handler with a "A" coil upgrade to support 13+ SEER if I ever replace the outside unit. Is the dripping normal in high humidity conditions as I describer?

Dripping Case

I obviously did not phrase my question well. What I meant was the case is sweating like a can of soda or beer taken out of the refrigerator and opened so that beads of moisture form on the can.

the case should be insulated if it is not in a conditioned space. If it is in a conditioned space then you need a dehumidifier.
