Air duct cleaning in Salem typically costs between $300-$800 for residential homes, depending on system size, ductwork accessibility, number of vents, and contamination severity. According to the National Air Duct Cleaners Association, professional NADCA-certified cleaning includes comprehensive video inspection, source removal methodology using truck-mounted vacuum systems generating 10,000+ cubic feet per minute, and HEPA filtration preventing recontamination. Salem homes in Marion County with multiple HVAC zones, extensive ductwork in older construction, or heavy wildfire smoke contamination from Oregon fire seasons may require more comprehensive service.
