Our Professional Duct Cleaning Process
Pre-Inspection
We inspect your ductwork with specialized cameras to assess contamination levels, identify mold growth, and locate any ductwork damage or pest issues.
Negative Air Pressure Setup
We create negative pressure in your duct system using powerful HEPA-filtered vacuum equipment to prevent contaminants from spreading throughout your home during cleaning.
Mechanical Agitation
Using specialized rotating brushes and compressed air whips, we dislodge debris, dust, and buildup from duct walls throughout the entire HVAC system including supply and return ducts.
HEPA Vacuum Extraction
A powerful truck-mounted or portable HEPA vacuum removes all loosened contaminants from your ductwork, capturing particles down to 0.3 microns - including mold spores, bacteria, and allergens.
Sanitization (Optional)
We can apply EPA-approved antimicrobial treatment to prevent future mold and bacteria growth, especially important in Seattle's damp climate.
Final Inspection
We verify cleaning quality with post-service camera inspection and provide before/after documentation showing the improvement in your duct cleanliness.

Frequently Asked Questions
How much does duct cleaning cost in Seattle?
Professional duct cleaning for an average-sized home (2,000-3,000 sq ft) typically costs $400-$800 depending on the number of vents, ductwork accessibility, and contamination level. Homes with excessive mold, pest infestations, or very dirty ducts may cost more. We provide upfront pricing after a free inspection with no hidden fees.
How often should air ducts be cleaned?
The National Air Duct Cleaners Association (NADCA) recommends professional duct cleaning every 3-5 years for most homes. However, homes with pets, allergies, smoking, recent renovations, visible mold, or pest problems should be cleaned more frequently - every 2-3 years or as needed.
How long does duct cleaning take?
Most residential duct cleaning services take 3-5 hours depending on home size, number of vents, and ductwork complexity. Very large homes or heavily contaminated systems may take longer. We'll provide an estimated timeframe during your free inspection.
Does duct cleaning really improve air quality?
Yes! Professional duct cleaning removes accumulated dust, allergens, pet dander, mold spores, and other contaminants that continuously circulate through your HVAC system. This significantly improves indoor air quality, reduces allergy symptoms, eliminates odors, and can improve HVAC efficiency. However, DIY cleaning or low-quality services may not provide these benefits - professional equipment and technique matter.
