FAQs

How often should air ducts be cleaned?

The EPA recommends every 3–5 years, or sooner if you notice visible mold, pest infestation, excessive dust, or after major renovations.

Is duct sanitization worth the extra cost?

Sanitization ($118–$168) is worth it if you have pets, allergies, or visible mold — it kills bacteria and mold spores that a standard vacuum-only cleaning won't remove.
