I have Central Air put in 2 years ago, first Winter, no problem...
However, this year, Water is leaking through the air vent.

Air handler is on the Attic (above 2nd floor), and the Condenser unit
is outside of the 1st floor.

When I went up to the Attic, I can tell there are good amount of water
in the duct and under the duct connected to the air handler and the
tubes that are connected to the air handler... How could this happen,
and how do I get rid of this problem...

Thank in advance for your input.
