Hvac mold on air handler: What to Check and What to Do Next

Do not run an air handler that you know or reasonably suspect is contaminated with mold, because airflow can distribute particles through the served space. From a safe location, document only what is already visible on the exterior, around accessible condensate or drain areas, at nearby supply or return grilles, and in the owner-facing thermostat or control display.
