Most Willamette Valley homes benefit from air duct cleaning every 3 to 5 years. That’s the interval published in ACR, the NADCA Standard for residential systems under normal conditions, and it shortens for homes with shedding pets, recent remodeling, or occupants managing allergies.

It’s worth knowing what the science does and doesn’t say. The EPA’s guidance on residential duct cleaning is condition-based rather than calendar-based: it recommends cleaning when there’s substantial visible mold inside hard-surface ducts, evidence of vermin, or debris heavy enough to restrict airflow or blow into the living space. The EPA is also clear that duct cleaning has not been demonstrated to prevent health problems. We’d rather tell you that up front than sell you something on a claim that doesn’t hold.

What we do see in this valley: grass seed farming makes the Willamette Valley one of the highest grass-pollen regions in the country from late spring through midsummer, and homes from Junction City to Keizer run recirculating forced-air systems through it. Combined with the October-through-May wet season, that’s a real load on a duct system. We inspect first, show you what’s actually in there, and give you a straight recommendation – including “you don’t need this yet.”
