Water dripping from duct vent

I discovered lastnight droplets of water dripping from one of the ducts and coming through a vent. The attic is particularly cool/cold compared to the rest of the house. Could this be a reason for the droplets of water ? Also, we received a good amount of rain the last couple days and weren't sure if this is a contributing factor. If anyone has any suggestions of fixing this, would be glad to hear them.

You dont say just what you have there. Is this just for AC this register and duct up in the attic or is it heat and cool?? Have you checked all the registers boxs in the attic??? For the insulation around them??

dripping from duct vent

The leak is actually dripping from return vent through the filter. A guy I work with suggested closing the vents to close off the heat and hopefully that will work. He thinks that its the warm air mixing with the cooling air in the attic, causing droplets of water to drip down.

Thats what it is. But just the cool air in the duct. The cold air return by the filter grill and duct there. Have you checked the insulation around it?

Yes it is the ac/heat ducts. I've closed the vents this morning, hopefully it will help. I noticed this morning moisture around all the vents, before closing them. As far as the insulation you were talking about, do I just check for a seal around it? And if need be, do I use any specific kind of sealant to put around it?
Thanks for the help.

All of that cold air return duct in the attic has to have good insulation on it There is Duct sealants
a mastic for teh duct . But I think its more in the way the ducts insulation is. You cant close off the register there you have to let the heat out
