The quick answer
Duct cleaning should not be sold as an allergy treatment. If indoor conditions concern you, separate the health question from the maintenance question: discuss symptoms with a clinician and ask a service provider to document the system condition.
Look at the whole indoor environment
Indoor air involves more than ductwork. Cooking, products used indoors, outdoor air and moisture can all matter. EPA guidance describes these multiple sources; symptoms alone do not identify which part of a home is responsible. EPA: indoor air quality fundamentals.
Make filtration a specific conversation
Bring the filter size and equipment model to the discussion. Ask whether the current filter fits correctly, what replacement schedule the manufacturer gives and which filter types the system can support. A portable air cleaner has its own room-size and maintenance requirements. EPA explains the roles and limitations of these devices. EPA: home air cleaners and filters.
What to ask a duct-cleaning company
Ask for a documented reason to clean and a written scope. Request an explanation of how the surrounding rooms will be protected and whether any products are proposed. Share practical household requirements before scheduling. Keep your medical decisions separate from a sales estimate.
- Which parts of the system were inspected?
- What condition makes cleaning appropriate?
- What is included and excluded?
- Is treatment proposed, and why?
- What maintenance or repair remains afterward?
