An older Norfolk home does not automatically need duct cleaning, and no cleaning method guarantees healthier air or protects every historic finish. The system's materials, condition, and access should guide the assessment.
Document the concern and protect the system
EPA says cleaning may be considered when substantial visible mold is documented inside hard-surface ducts or HVAC components, vermin are inside the ductwork, or excessive debris is released from registers. Ask the provider to show the condition and explain how the proposed method fits the duct material and scope.
Correct moisture, pest entry, or damage separately. EPA says wet or moldy insulated duct material cannot be effectively cleaned and may need replacement. Routine cleaning has not been shown to prevent health problems.
