Hi all, I just stumbled upon the site. I am having the exact same issue and need a contractor here in Dallas. I had one come already and perform a blower test. The results were not much leakage but I am still smelling smoke. My new town home does have a positive pressure vent but I am afraid it might not be enough. Should I also open a windown and get a fan?

Please help! It's killing me slowly.

Thanks
