I believe the water you are seeing is the moisture that is condensing on the coils. It is perfectly normal, however, there should be a discharge pipe (in my case it is white tubing) that the water flows through to a drain.

There should be a drain line from the pan under the AC coil in your furnace. It is normal for water to be discharged from this drain line when the AC is operating. If you are getting water out on the floor the drain line is probably plugged and water is overflowing the drain pan. Some installations have a cleanout on the trap on the drain line. If yours does then open the clean out and probe/flush to remove the blockage. If that doesn't work or there is no cleanout the solution is to turn all power to the furnace off and remove the access panel to the AC coil and then use a probe or wire to insert in the drain line to dislodge the blockage. Use clean water to flush the line until it runs freely.

If you google: ac drain line furnace
and then select "images" you'll see pages of furnaces with drain lines. One of them should help you find yours.

Did you install the air conditioning yourself as a retrofit to the furnace? Did it ever run without leaking water all over the place? Did you ever install a drain hose or other means of getting rid of condensed water?
