Hole in the duct? Is this right?
I'm really not sure what the names of the parts of my furnace are but I will do my best to describe what's happening:
Our furnace unit is located in an outside closet. Standing in front of the unit, I see the furnace, above that I see the indoor coiling unit, and above that is a steel chute that leads up (to the roof/ceiling I guess). I've noticed in the steel piece is a perfectly round hole about 1" in diameter. Is that supposed to be there? Wouldn't air come out of that instead of going into the duct system?
Thanks for any suggestions.
