Leak under Air Conditioning Vent

[Rangerpr]

During the Summer, there is a leak that develops from under the vent that is sitting right above one of the kitchen cabinets. During the winter there is no problem I guess because there is no warm air to hit the cold coming out of the vent. This summer it was pretty bad because it was so hot in Virginia. I had an AC guy coming in but didnt say anything about the condensation. Has anyone had this problem before?

make sure the condensate line is not clogged and check the smitty pan the unit sits in for any signs of water. also is there a condensate pump in attic

I do know some high humidity areas have to install another doo-hickey (similar to a dehumidifier heating coil) which stops the moisture from dripping out of the vents. I'm sorry for not knowing more on this topic, buy did watch a segment on a home repair TV show. Please give a local heating/air conditioning company and see if they could guide you better.

Also, if successful, please let us know the actual name of this part so I can eliminate the "doo-hickey" from this thread.

If your a/c ducts are sheet metal you should have them insulated ,you are probably getting condensation from the cold metal and the hot attic. If your ducts are flex ducts , then make sure the take off & the register boot are insulated
