The EPA and NADCA suggest cleaning air ducts every 2–3 years for most homes. However, homes with pets, smokers, allergies, recent renovations, high dust levels, or water damage should consider annual cleaning. If you see visible dust puffs from supply vents, experience lingering odors, or notice uneven airflow, it’s time to schedule service.
Regular duct cleaning helps protect indoor air quality, keeps your HVAC running efficiently, and extends the life of your system by removing debris, dander, and microbial growth from supply and return runs, registers, and the blower compartment.
Recommended: every 24–36 months (or annually for high-traffic homes)
