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)
