A young contractor friend of mine in Las Vegas called me today about a problem...
Seems water is dripping out of an a/c duct in an 18,000 sq,ft. house he is doing repairs on.the house has humidifiers on each zone(13 a/c units).He is repairing damaged drywall from a water softner line that leaked up in the ceiling(supplying the humidifiers).He checked for a roof/plumbing leak.Found none.I thought it was probably condensation but hvac is not my area.
Any ideas...Thanks (can't finish repairs with water issue unresolved)

Is he working in Wayne Newton's house? LOL

Put insulation for duct work around the ducts. It will prevent the cool air from coming in contact with the ambient air which is what is causing the condensation.

He is going to have to look a little further. You stated inside the duct, no comment about sweating on the outside. The cooler air in the duct should below the dew point.

Going to have to look at where in the system it is leaking, could be a humidifier with a problem, condensate from a coil, or some other off the wall problem not associated with the AC.

Thanks for your input...
There was a problem with one of the humidifiers.They have been an ongoing problem for the owner since the beginning.This house is huge(3 story).The concensus is things are not being maintained in a timely manner...

If the dripping water is a constant drip there may be a copper water line that has contacted the duct work and electrolysis has caused a small constant leak.
