I'd like to check into getting my ducts sealed but I have mostly unexposed ductwork due to the flat roof. What do you think of the aerosol duct sealing? Are there any other ways to seal unexposed ductwork?
Maybe look into getting some exterior insulation installed on that flat roof. That would help protect the ductwork from extreme temps & make the leakage less of an issue.
Yeah I was thinking about that too. I mean, if the air leaks out of the duct it can only go into the roof truss space which is about 2 ft high. I know that space gets real hot as I've had to make openings in it.
I may need the roof done soon so that would fit in nicely.
