Why SeaTac Homeowners Choose Bellows Air Duct & Vent Co. of Seattle
We’ve been pulling decades-old debris out of SeaTac ductwork for twelve years now. The homeowners who call us tend to be the ones who’ve already learned the hard way - a coupon special that showed up late, upsold half the house, and left the registers still coughing dust. They want the job done right, documented, and finished.
Our technicians know the difference between a 1962 ranch near Angle Lake and a noise-insulated split-level off Military Road South. Both get the same treatment: camera inspection before we touch a thing, camera inspection after we’re done, and a 90-Day Done Right Promise in writing. If something’s not right, we come back. No paperwork, no arguing.
Calls to our office reach a live person 24 hours a day. Background-checked, uniformed technicians arrive when we say they will. And the price we quote on the phone is the price on the invoice - no bait coupons, no surprises at the door.
Air Duct Cleaning Services We Offer in SeaTac
Air Duct Cleaning
We clean the full supply and return network with Rotobrush and Nikro professional-grade equipment, removing built-up dust, debris, and contaminants from every accessible run. Camera verification before and after documents what came out and what condition your system is in now. Learn more about our Air Duct Cleaning in SeaTac.
Dryer Vent Cleaning
Lint accumulation in dryer vents is a leading cause of residential fires, and SeaTac’s older housing stock often has vent runs that are too long, too bent, or partially blocked by decades of buildup. We clear the full line from appliance to termination and test airflow before we leave. Learn more about our Dryer Vent Cleaning in SeaTac.
HVAC Cleaning
Coils, blower assemblies, and plenums collect what ducts push through them. We clean the full air handler so your system isn’t re-contaminating itself the week after the ductwork gets cleared. Learn more about our HVAC Cleaning in SeaTac.
Duct Repair & Sealing
Original galvanized or early flex ductwork in SeaTac’s post-war homes cracks, separates at joints, and leaks conditioned air into crawl spaces. We repair or replace damaged sections and seal the system to restore proper pressure and efficiency - learn more about our Duct Repair & Sealing in SeaTac.
Air Quality & Sanitizing
For homes with documented mold, persistent odors, or post-remediation needs, we apply EPA-registered treatments using equipment from Abatement Technologies and Guardsman - see Air Quality & Sanitizing in SeaTac for details. This is not a substitute for proper duct cleaning, but a targeted add-on when conditions warrant it.

Why SeaTac’s Climate & Housing Affect Air Duct Cleaning
SeaTac sits in a pocket of the Puget Sound lowland that gets about 145 wet days a year, and that marine humidity doesn’t stay outside. It seeps into unconditioned crawl spaces, condenses on cool metal ductwork, and creates the exact conditions mold needs to colonize. In a typical 1950s ranch off Military Road South, we’ve found galvanized supply runs with rust pitting so severe the interior surface is flaking into the airstream. The homeowner smelled something musty every time the furnace cycled; what the camera showed was a decade of moisture damage no filter could catch.
Then there’s the factor no nearby city shares. Thousands of SeaTac homes fall inside the Port of Seattle’s Noise Insulation Program footprint, retrofitted with tight envelopes and new windows to blunt jet noise from Sea-Tac Airport. The shell got sealed. The ductwork usually didn’t. Now those houses recirculate air with far less dilution from outside, and the particulate load - including ultrafine jet-exhaust particles that migrate into residential zones - concentrates in ducts that haven’t been cleaned in twenty or thirty years. We’ve opened systems in noise-insulated homes near Angle Lake where the interior buildup was visibly darker and more carbon-heavy than comparable homes in uninsulated Burien, our Normandy Park service area, or Des Moines. The envelope was doing its job. The ducts were not.
High rental density in pockets like McMicken Heights adds another layer. Tenant turnover means HVAC systems run hard with minimal maintenance between occupants. By the time an owner or property manager calls us, the return plenum is often packed with a composite of pet hair, cooking grease, and construction dust from quick-turn renovations. It’s a specific wear pattern we see regularly in SeaTac’s airport-service housing stock, and it takes more than a shop vacuum to correct.

FAQs About Air Duct Cleaning in SeaTac
Most SeaTac homes fall between $350 and $650 for a complete residential air duct cleaning, depending on system size, register count, and accessibility. We quote your exact price before we start - no bait coupons, no changes at the door. Call (833) 700-5198 for a free estimate.
Every three to five years for typical households, though SeaTac’s noise-insulated homes and high-humidity crawl spaces often warrant closer to three years. If you’ve never had ducts cleaned since buying a 1950s-1970s ranch or split-level in the 98158 ZIP, you’re likely overdue. Call (833) 700-5198 and we’ll camera-inspect to tell you where things stand.
Yes - in fact, we specialize in the tight-envelope homes the Port of Seattle retrofitted around Sea-Tac Airport. Those sealed shells recirculate air with minimal outside dilution, so duct contamination concentrates. We adjust our process to protect the envelope while thoroughly cleaning the original ductwork those programs typically left untouched. Call (833) 700-5198 to schedule.
Repair and sealing is usually the more economical path for SeaTac’s post-war housing stock, provided the metal or flex runs are structurally intact. We camera-inspect first and show you what we find. If replacement makes more sense, we’ll say so - no upsell, no scare tactics. Call (833) 700-5198 for an honest assessment and free estimate.
