    Blower to run intermittently causing cold air...
    How do I delete or turn this function off? The AC and Heating works perfectly. Beutler installed the whole system and said KB Home wanted it to help with mildew, however, this causes cold air to blow because it blows between cycles.

    It would probably be better to just adjust your vent position if mold and mildew is a real issue. What part part of the country are you in?

    But read this first,

    And

    Many areas now require builders to have intermittent running fans to be installed and this appears to be your situation.
