okay i want to turn the heat on at my house but i have a few questions.
during our home inspection that was found by the inspector after he got the attic hatch open.
this is what i see when i look towards where the rope goes, and yes the one that pulls to the right is not attached anymore.
this is the view of the roof

the duct work on the far right is the return and the one in the middle is the one that sends the air into the bedroom side of the house the one going at a right angle to the others goes to the living rooms and kitchen.
the question i have is is this dampaner even in use any more?.... could it have been to close off an older swamp cooler?
