  • Excess moisture in the crawlspace can absolutely cause condensation on the HVAC ducts when the AC is running. Especially if the ducts are uninsulated or poorly insulated, as is often the case in older homes.

    Get a dehumidifier and dry it out. If needed, you could run the dehumidifier in the basement and put a fan in the crawlspace opening to circulate air.

    The dehumidifier may be necessary even after the crawl space is dried out. We always have to run one in our basement in the summer.

    That said, there are zero reasons why the condensate line should have been terminated in the crawl space. Dealing with incompetent contractors sucks.
