Central Ac Not Cool Enough To Turn Off On Hot Days!

We moved in our newly built home in Feb 2003. The house is 4100 sq ft and we had a builder installed Goodman AC unit. The central ac unit worked fine until the summer of 2008. It started running continuously when the temperature reached 90+.
It worked fine at night when the temp dropped but during the day the thermostat remains on 80 degrees while the central air is running. After hundreds of $ and numerous "AC repair technicians" my problem is still not fixed even though I bought a bigger outdoor and indoor unit last summer.
The central ac unit is a Ducane and the Model # is 2AC13148P-2A and the Serial # is 4609E48972. I still have the same problem. There is no leak in the attic duct system, there is enough Freon in the ac unit, the indoor coils are clean, the dampers have been turned in every direction and there is no leak in the outdoor unit.
It is cool in the basement but the second level is bearable and the upstairs is hot. Have you ever heard of this and what can I do to fix it. I need a repair person to FIX THE PROBLEM and not charge me $100 to come out and not fix it!!!
