Found Paul in the auxiliary/emergency pan. Caused by electricians when home was built. Technician lifted this corner of the pan so that it will be above the rest of the emergency panel. Dried and siliconed hole. As for why there is any water in the pan. I the technician believe that when the outdoor unit was washed the refrigerant pressures reacted, and at night when the customer lowered the thermostat from 80 to 74° some ice is developing and this ice is then melting and dripping down getting into the auxiliary pan.
