Air Duct Cleaning Services We Offer in Seattle
Air Duct Cleaning
We clean supply and return ductwork throughout your home using professional-grade brushes, HEPA-negative-air containment, and camera verification before and after. Seattle’s damp climate and retrofitted duct systems demand more thorough contact cleaning than drier markets require. Learn more about our Air Duct Cleaning in Seattle.

Dryer Vent Cleaning
Lint accumulation in dryer vents is a leading cause of house fires nationwide, and Seattle’s humid air causes lint to clump and stick more aggressively than in arid climates. We clear the full run from appliance to exterior termination and verify airflow with a meter. Learn more about our Dryer Vent Cleaning in Seattle.

HVAC Cleaning
Blower motors, evaporator coils, and plenums collect the same debris as ductwork but rarely get addressed during standard maintenance. Our HVAC cleaning service restores system efficiency and reduces the particulate load your filter was never designed to catch alone. Learn more about our HVAC Cleaning in Seattle.

Duct Repair & Sealing
Seattle’s retrofitted ductwork - especially flex-duct splices in unencapsulated crawl spaces - separates, crushes, and leaks over time. We repair damaged sections and seal joints with mastic and mechanical fasteners, not tape that will fail in six months - learn more about our Duct Repair & Sealing in Seattle.

Air Quality & Sanitizing
For homes with documented mold, rodent activity, or post-wildfire smoke contamination, we apply EPA-registered biocides and deploy HEPA air scrubbers during service as part of our Air Quality & Sanitizing in Seattle. This is not a routine upsell - we recommend it only when camera inspection shows biological contamination that mechanical cleaning alone won’t address.

Neighborhoods We Serve in Seattle
We run calls across the city, from the historic districts to the hillside developments. Most Seattle neighborhoods see us within 24-48 hours of scheduling.
- Capitol Hill - pre-WWII homes with retrofitted ductwork in basements and crawl spaces
- Ballard - Craftsman bungalows with original oil-to-gas heating conversions
- Rainier Valley and Beacon Hill - mid-century ramblers with flex-duct runs through wet crawl spaces
- Seward Park - older homes where rodent and mold issues often coincide in the same duct runs
- West Seattle - hillside drainage issues compound crawl-space moisture problems
Why Seattle’s Climate & Housing Affect Air Duct Cleaning
Seattle’s persistently damp marine climate - combined with the historical rarity of central air conditioning in pre-2000 homes - means ductwork almost never runs the dehumidifying cooling cycle, allowing moisture, mold spores, and bio-debris to accumulate inside supply and return runs in ways that simply don’t occur in drier markets. Layered on top of this, the Puget Sound basin’s topography traps Cascade and Eastern Washington wildfire smoke for days at a time during increasingly severe smoke seasons, driving residents to find fine particulate matter (PM2.5) embedded deep in their duct systems months after an event.
Seattle’s dominant housing stock - pre-WWII Craftsman bungalows and foursquares across Capitol Hill, Ballard, and Columbia City, plus 1950s-1970s ramblers on the Eastside slopes - was largely built without central forced-air; ductwork was retrofitted later, often running through unencapsulated crawl spaces that sit directly on Seattle’s notoriously wet glacial soils. These retrofitted systems tend to have more joints, flex-duct splices, and irregularly sized runs than purpose-built systems, compounding contamination and making cleaning more labor-intensive. Seattle averages relative humidity above 75% for most of the year, and crawl-space ductwork under older homes is regularly exposed to ground moisture and vapor intrusion, creating conditions where rust, mold colonies, and rodent debris accumulate faster than in any comparable West Coast city with drier soils.
Techs working Rainier Valley, Beacon Hill, and Seward Park frequently pull ductwork from original oil-to-gas-converted systems where the flex-duct connections into crawl spaces have collected both mold and rodent nesting material in the same run - a combination rare in drier markets but predictable enough in Seattle’s wet-crawl-space neighborhoods that experienced crews pre-stage biocide treatment and HEPA containment before they even pull the register covers.

FAQs About Air Duct Cleaning in Seattle
Most Seattle homeowners pay between $350 and $650 for a complete residential air duct cleaning, depending on vent count, system accessibility, and contamination level. Older homes in Capitol Hill or Ballard with retrofitted crawl-space ductwork often require additional time and HEPA containment, which can push larger systems toward the higher end. Call (833) 700-5198 for a free, exact quote - estimates are free and come with no obligation.
Every three to five years for most Seattle homes, though homes with pets, recent wildfire smoke exposure, or visible mold should be inspected sooner. Seattle’s 75%+ annual humidity and lack of cooling-season drying cycles mean bio-debris accumulates faster than in drier climates - many of our Capitol Hill and Rainier Valley customers benefit from closer to a three-year interval. Call (833) 700-5198 and we’ll assess your specific situation.
Mechanical cleaning removes the particulate matter (PM2.5) that carries wildfire smoke odor, but embedded smoke residue sometimes requires combined mechanical cleaning plus sanitizing treatment. Seattle’s basin topography traps smoke for days, and we’ve found particulate deposits in ductwork months after major smoke events - particularly in homes that ran continuous fan mode during poor air quality days. Camera inspection will tell us whether mechanical cleaning alone will solve it or if air quality sanitizing is warranted.
Repair and sealing is almost always more economical than full replacement - or Lennox repair in Seattle - for the localized damage we typically see in Seattle’s retrofitted systems - separated flex-duct joints, crushed runs, and leaky connections in crawl spaces. Full replacement only makes sense when ductwork is extensively corroded from long-term moisture exposure or when the original retrofit was so poorly designed that cleaning cannot restore function. We’ll show you the camera footage and give you both options with upfront pricing before you decide.
Same-day and next-day appointments are often available, especially for urgent situations like post-rodent contamination or visible mold concerns. Our office answers live 24 hours a day, and most Seattle neighborhoods see us within 24-48 hours of calling. For fastest scheduling, call (833) 700-5198 - we do not book through apps or online portals because we’ve found Seattle homeowners prefer speaking with a person who can answer questions and confirm exact pricing.
