I live in Maine - I recently have developed water stains around several HVAC vents in my ceiling. When I reach up into the duct there are small pools of water which are getting trapped in the flexible ductwork which in turn drips down onto my vent cover and causes the stains around my ceiling vent.
I do not know how to stop this condensation from occuring - I have NOT run my unit (central air / heat pump) for nearly one month because it is freezing here.
My home is warm - the attic (where all the duct work is located) is cold
There must be some way to prevent this condensation issue - anyone more educated on this topic?
