Hi, About 2 years ago, I had a Central Air unit and new Furnace installed in my 1926 home. Never had Central Air before. Well... Now whenever I run the air cond. or furnace (AC WORSE by quite a bit) The air coming from the vent stinks like the mildewy basement. I was told that the unit will suck air from wherever it can get it including seams in duct work, therefore from basement area that stinks. I cleaned the basement as well as I could on a budget. Scrubbed walls, sprayed bleach on them and painted with drylock. Also got dehumidifier. The basement is almost always dry now and stinks less than before. However my whole house reeks of mildew completely now. City inspector said he'd never seen this before even in old homes. Help?? Guess theres likely nothing to be done, but any advice is welcome...
