I am having odor issues in my house that I think are coming from the basement which has a mix of must and cat odor.
The second floor doesn't seem to smell, which is why i think it's coming from the basement. It's worst in the morning. And when I turn on my heat or a/c, that odor comes through my vents! 1) I have a very good Santa Fe dehumidifier running, 2) I've had the ductwork checked and it's fine. 3) I've been told by multiple hvac guys that i just need to seal the air leaks along the galvanized ducts, which I've done with foil tape to the best of my ability. Could there be a problem with the hvac system beyond the air leaks? Do I need to take measures to seal the floor and walls to remove the odor in the basement?
