18 Year Old Trane Furnace Smells Musty
I just bought a condo that has an 18-year-old Trane Furnace. When the furnace runs, it causes the whole condo to smell musty and tends to make me cough. Also the tiny drain hoses are plugged somewhere and backing up causing water to leak out of a small blower housing. I have disconnected it from the housing and routed the hose into a bucket for now. What should I do for each separate problem, or could they be connected?
