Attic Air Handler Drain Pan Empty - Emergency Drain Pan Not Empty

About two years ago I had central heating and air installed into my 1,200 square foot home. The air handler is installed in the attic. It is hanging from the rafters with an emergency drain pan underneath it. I go into the attic on a periodic basis to check the unit and often find the emergency pan full of water. I had the installer come check the unit on two occasions. The first time I was told the unit was sweating and that it was normal. The second time I was told the primary drain maybe slightly clogged so he blew it out with a portable air tank but the emergency pan continued to fill. Today I open up the air handler to find the drain pan inside the unit empty and the insulation in the bottom of the unit to be completely soaked. It appears the bottom of the unit is filling up with water and then dripping out into the emergency pan. The installer was suppose to come out last week to check it but has yet to show up. Can someone please point me in the right direction?

When you say airflow issue do you mean the drainage piping / P Trap may not be setup correctly?

Another possibility is a cracked primary pan. Is the primary drain trapped & have a vent downstream of the trap?
