Mold and HVAC

Canonical HVACentric knowledge for all questions on this topic.

DIRECT ANSWER

Mold requires moisture, so the priority is finding and correcting the water or humidity source. HVAC work may be part of the solution when drainage, coils, insulation, ducts, or humidity control are involved, but a filter or air cleaner does not correct active moisture. Large, recurring, hidden, or health-sensitive situations may require a qualified mold or indoor-environment professional in addition to HVAC service.
