This morning I get a call from my wife that there is water dripping through the Central Air vent in the kitchen. I had been in that area about three hours earlier and there was nothing. Naturally the concern is that there's a roof leak, but the last time it rained was a couple of days ago and there's no staining or bulging in the ceiling. This is strictly a central air vent; we have baseboard heat.
My father-in-law went by and said that the drip was coming from inside the mouth of HVAC pipe/ductwork itself. The vent is located in the area where my wife cooks, washes dishes with hot water, etc. Could the steam from that been trapped in the HVAC, froze in the cold temperatures, and then melted when the sun started hitting the roof in the morning? Any another explanation?
One possibility.
when I moved into my house the stove exhaust just went into the attic, it wasn't vented.
We had an electrician install a vent.
I don't know if it would cause the condensation like you're seeing, but thought I'd share that.
One possibility.
No snow, but thanks.
