Harry chickpea-those are very good suggestion. I also think is going on, maybe ice is accumulating somewhere and when the a/c stop the ice start to melting...i dont think this water is coming from the pan. Are we suppose to have a p-trap somewhere on this a/c?
I've never been aware of any requirement for one. A condensate line going into a sewer would need one, but an open system pan to ground wouldn't. I suppose there is a possibility of bugs crawling up the inside, but that is pretty remote.
If the condensate drain is a long run you may need to vent the pipe perhaps drilling a 1/4 inch hole ahead of the trap, assuming this is pvc pipe. Also, in cooling, running the fan continuously should produce less condensate.

We are still trying to find this leak. I poured a little water on the Evaporator Coil and the water dripped all the way to the carpet. I thought it was suppose to go to the drain pan. We opened all the vents and its been raining everyday down here. This leak is driving crazy ;-(.

It's hard to tell from the photo but it looks like the coil is compleyely frosted over! The fan IS running, right? Is the cooling cycling on the thermostat setpoint or is the cooling running continuously? Is the filter clean?

The coils are very clean and no frost. I attached the bottom of the coils. We are trying to catch the leak but it happens at night. Can the outside unit cause the leak if so how?
It sounds to me like you have an air problem; not enough air flow over the coil. It also sounds like the cooling runs all day and finally satisfies the thermostat at night and then cycles off and the frost/ice buildup on the coil melts. One sees this a lot with window units where people run the fan in low speed and crank the thermostat to the coldest setting and the coil eventually frosts over. The outside unit has nothing to do with it.
If your filter is under the coils, get a cheap pleated filter, put an even dusting of baking soda on it, and stick it in the filter housing for one night. If the baking soda is wet or caked in the middle of the filter, you have a freeze-up issue. If it is wet around the outside, you may have a leaky drain pan.

UPDATE****The a/c does not run all day. During the day we have thermostat set to 79 and in the evening at 77-75. Okay so few minutes ago we just heard a leak ran upstairs took out the filter and under the coils we have ice build up. So ice is behind the coils. So now that we found ice how do we solve this problem?
We had changed the filter beginning of April and we use the expensive type $5 at Lowes...Maybe be the air is not flowing through http://www.lowes.com/pd_153049-87308...ductId=3014141

Is the inside unit located in the attic? If so, is it perchance insulated? Does the outside unit seem to run a lot? What type of thermostat do you have? Is the house insulated? If there is a bit of a refrigerant undercharge in the system ice can form around the coil inlet. You should bite the bullet and have a service tech look at it.
