If you are not loosing any fluid,s from radiator,could just be humidity,pulled out by ac.If it is blowing threw fan,then clean drain hose.

Condensation in high or mid high humidity areas will produce a lot of run off. Make sure the drain hoses are clear. Even in low humidity areas like the S.W. US there is condensation that leaves a puddle under the car.
