Why Seattle Homeowners Choose Bellows Air Duct & Vent Co.
We’ve been driving to Seattle jobs from our offices for over twelve years now, serving Kirkland, WA, long enough to know which Ballard crawl spaces flood in January and which Capitol Hill basements run narrow enough that we bring the compact Nikro unit instead of the full Rotobrush truck. That familiarity matters when you’re scheduling around a workday and need the crew to arrive when they say they will.
Our technicians are background-checked and uniformed, and every job starts and ends with a camera inspection you can see for yourself. The 90-Day Done Right Promise is stamped on every invoice in writing. If something isn’t right, we return at no charge, no paperwork, no arguing. That’s been our way since 1984.
We don’t use bait coupons or surprise fees at the door. The price we quote on the phone is the price on the final bill. For homeowners who have lived in the same house for twenty years or more, that predictability tends to matter more than a flashy discount.
Air Duct Cleaning Services We Offer in Seattle
Air Duct Cleaning
Our full-system mechanical cleaning removes accumulated dust, debris, and biological growth from supply and return ductwork using professional-grade Rotobrush and Nikro equipment. Every job includes before-and-after camera documentation so you see what came out of your system.

Dryer Vent Cleaning
Lint buildup in dryer vents is a leading cause of residential fires nationwide, and Seattle’s humid climate can cause lint to clump and stick more stubbornly than in drier regions. We clean the full vent run from appliance to exterior termination and verify airflow restoration with a digital anemometer.

HVAC Cleaning
We clean evaporator coils, blower assemblies, and plenum boxes where moisture and organic matter collect in Seattle’s high-humidity environment. This service is often paired with duct cleaning after the Pacific Northwest heat dome drove so many homeowners to install ducted heat pump systems in 2021 and after.

Duct Repair & Sealing
Retrofit ductwork in Seattle’s pre-WWII housing stock frequently suffers from disconnected flex-duct joints, corroded metal seams, and gaps where ducts pass through unsealed crawl space walls. We repair and seal these leaks with mastic and mechanical fasteners, then verify with pressure testing as part of our Duct Repair & Sealing in Seattle.

Air Quality & Sanitizing
Given Seattle’s persistent indoor humidity, we frequently apply EPA-registered biocide treatments after mechanical cleaning to address mold and mildew colonization in fiberglass-lined ducts as part of our Air Quality & Sanitizing in Seattle. This step is standard in our market but rarely needed in drier climates.

- Queen Anne (98109) - steep grades creating chronic moisture issues in under-floor systems

We also cover the full span of ZIP codes 98114, 98115, 98116, and 98117, plus surrounding areas.
Why Seattle’s Climate & Housing Affect Air Duct Cleaning
Seattle’s marine west coast climate keeps indoor relative humidity at 75-85% year-round even when it isn’t raining. That moisture allows mold spores already present in Pacific Northwest air to colonize duct interiors within months, particularly in fiberglass-lined supply ducts that sit unused through mild summers. Unlike desert or Midwest markets where duct cleaning addresses primarily dust accumulation, Seattle jobs routinely require EPA-registered biocide application after mechanical cleaning to address biological contamination.
The housing stock compounds the problem. Central Seattle is dominated by pre-WWII Craftsman bungalows, Tudor Revivals, and American Foursquares, most built with boiler or radiator heat and retrofitted with forced-air ductwork during mid-century renovations. In hilly neighborhoods like Queen Anne and Beacon Hill, those retrofit runs frequently travel 20-30 feet through fully vented crawl spaces that sit inches above damp soil on a steep grade. These sections are invisible from the registers, but our duct cameras almost always find them colonized with mold, a failure mode essentially unknown in flat-terrain cities where basement duct runs stay conditioned and dry.
Since the 2021 Pacific Northwest heat dome triggered a citywide rush of ducted heat pump installations in homes that had never previously had central air, there is now a newer layer of hastily installed flex-duct systems warranting early inspection for poor sealing and moisture infiltration. We see these regularly in 98115 and 98116.

FAQs About Air Duct Cleaning in Seattle
Most full residential cleanings in Seattle fall between $350 and $650 for a single system with up to twelve vents. Homes with additional HVAC zones, extensive mold remediation needs, or hard-to-access crawl space runs may run higher. Call (844) 685-6342 for a free estimate tailored to your house.
Given Seattle’s sustained high humidity and mold-friendly climate, we recommend inspection every two to three years and cleaning every three to five years for typical households. Homes with retrofit ductwork through vented crawl spaces, like many in Ballard and Fremont, often need more frequent attention. Call us to schedule a camera inspection and we’ll show you exactly what your system looks like inside.
Yes, this is our specialty. We’ve cleaned ductwork in hundreds of pre-WWII Seattle homes where forced air was added decades after construction. The compact equipment from Rotobrush and Nikro handles tight crawl spaces, and our technicians know how to protect fragile original finishes. Learn more about our Air Duct Cleaning in Seattle.
Unfortunately, yes. Seattle’s 75-85% indoor relative humidity and mild summers allow mold to colonize duct interiors far faster than in drier climates. Fiberglass-lined ducts are particularly vulnerable. We address this with mechanical cleaning followed by EPA-registered biocide application, then verify results with post-cleaning camera documentation. Call (844) 685-6342 if you smell mustiness when your system runs.
We answer calls with a live person 24 hours a day, and we can usually schedule within three to five business days for standard appointments. True emergency response is available for dryer vent blockages posing fire risk or complete HVAC system failures. For fastest scheduling, call (844) 685-6342 rather than using email.
