  1. I'm told that taping the joints on exhaust vent pipes is no longer recommended, and that the joints won't leak because the furnace motor will push the exhaust through. Just trying to confirm.
  2. I have a 1925 home in Philadelphia. Just purchased in January this year. It's a duplex with one unit on the first floor and one unit on the second floor. I had a new dusct system installed on first floor unit and a separator to get a thermostat on each floor and send the air where needed.

I have attached some pics. I have a couple of concerns and wanted to get your input on these.
