Re: ac vent drips water

If your attic is well insulated you may want to put a piece of cardboard at the grill or put a piece of insulation in the ductwork at the opening to keep the warm air out of it, it may be condensing and freezing then thawing. That's all I can think of, I'm sure someone will be along to give you more or better info.
Good Luck!!! :)

Re: ac vent drips water

It sounds like some of the tubing may not have been sealed properly. Do you have a warranty or anything for the unit? If you an, call the installer and ask what they think or suggest for you to do. Perhaps it's under warranty and they will be willing to come out and fix it.

If the vent is not used for your heater then use 2" foam board cut to fit to seal it off.

My first thought that the duct is run through the attic space and for some reason is not insulated,thereby showing frost in the outlet box. Sounds like an exploratory trip into the attic to see what's there is in order.
