There's no specific source of the odor, but it only occurs when it's very warm outside. It's done this for several years and a completely new H/AC system. AC drains outside. It doesn't appear to be caused by open traps and we really can't find a general smell in the crawlspace ( although I must admit, I can't get down there when it occurs because the entrance to the crawl is too small for me). The house is 50 years old but is very tight. There's no smell in the attic. Plumbers report no smell in the crawl, but haven't been down when the smell occured. The mystery is worse than the odor. It smells bad, but not horrible. It's not a moldy smell, although the crawl is typically cool and musty. The only consistencies are the outside hot temperature and the use of the AC being the triggers-no problem in the cooler morning or evening AC or using the heat in the winter. If someone can figure this out, a small army of baffled plumbers and sewer experts (and us) will be greatful!
