Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterFast, Reliable Air Duct Cleaning Across Seattle
Air duct cleaning in Seattle runs $450 – $750 for most single-family homes with one furnace and up to 18 supply vents, and the job usually takes half a day. We work across the city from Rainier Valley to Ballard, and we arrive with a written price before any work starts. No per-vent pricing, no discovered problems that suddenly change the bill. If you live in Seattle and your home’s air feels stale, dusty, or inconsistent from room to room, call (737) 727-2314 and a live person will answer.
Why Cardinal Air Duct Cleaning Is Seattle’s Preferred Air Duct Cleaning Company
Seattle homeowners keep calling us back because we run honest equipment and honest pricing. Our technicians carry professional-grade gear – Rotobrush agitation systems and Nikro HEPA vacuums – instead of shop vacs bolted to a truck. That matters in a city where older homes in neighborhoods like Crown Hill, Wedgwood, and Beacon Hill have duct runs hidden in crawlspaces that a weak vacuum cannot pull clean.
Every booking goes through the Relay Standard. That means you get a live trackable arrival window before the van shows up, before-and-after photos of your actual ducts once the job is done, and a digital invoice you can pay from your phone. No four-hour waiting windows, no wondering who is at the door. Our technicians are background-checked, in uniform, and named on your booking confirmation.
Omar Haddad leads our Seattle team, and the standard he holds is simple: if the work isn’t right within 365 days, we come back and make it right at no charge. That promise covers every job, not a select few. That is the kind of guarantee you can actually enforce, and it is why Seattle homeowners refer us to neighbors on Capitol Hill, in West Seattle, and out toward Lake City.
Air Duct Repair in Seattle
Air duct repair in Seattle typically runs $250 – $600 depending on whether we’re resealing a single leaking joint, replacing a crushed section of flex duct, or correcting return airflow in a crawlspace. Most repairs in this city involve ducts that have worked loose in unconditioned crawlspaces or attics, where seasonal moisture and rodent activity take a toll on tape, mastic, and insulation. We find the problem with live camera inspection, show you the footage, and quote the fix before the repair starts. If the repair fails within 365 days, we return and fix it again at no charge.
Leak Sealing and Insulation
A disconnected return duct in a Seattle crawlspace pulls dirty air straight into your blower and through every room. We locate these gaps with the Rotobrush camera, seal them with mastic and metal tape, and re-insulate where moisture has caused deterioration.
Condensation and Moisture Damage
Seattle’s marine air means ducts in unconditioned spaces sweat. When insulation gets saturated it sags, grows mold, and robs the system of heating and cooling efficiency. We replace damaged insulation wraps and adjust the duct runs so condensation drains away rather than pooling.
Ductwork Cleaning in Seattle
Ductwork cleaning in Seattle costs $450 – $750 for a full-system cleaning that includes supply and return ducts, the air handler, and the blower motor. We clean under negative pressure, which means the Rotobrush loosens debris while a Nikro HEPA vacuum draws it directly out of the duct and into a sealed containment unit. That is standard source removal, not an air wand waving through a register. The process removes dust, pet hair, construction debris, and the fine particulate that Seattle’s damp winters trap and recirculate.
Full Supply and Return Cleaning
We don’t skip the return side. In Seattle’s older homes, return ducts often pull from the coldest, dustiest part of the house, and they’re frequently more clogged than supply lines. We clean every run, show the camera footage, and leave the system visibly cleaner.
Air Handler and Blower Cleaning
A dirty blower motor works harder than it should and shortens the life of your furnace. We clean the blower, the heat exchanger, and the coil, then fire the system back up and verify static pressure before leaving.
Trusted Brands We Service in Seattle
Seattle homes carry every brand imaginable, from 1980s-era Tempstars to modern Trane and Carrier setups, and our team services them all. We stock common replacement parts locally for the makes we see most often between Ballard and South Seattle, which means faster turnaround on duct repair work. Our equipment list includes Abatement Technologies containment units and Guardsman filtration products alongside our Rotobrush brushes and Nikro vacuums. If you’re not sure what’s inside your ductwork, that’s fine. We’ll identify it, photograph it, and tell you exactly what it needs to run clean.
Common Air Duct Cleaning Problems We See in Seattle Homes
- Crawlspace ducts that collect rodent debris and moisture. Seattle’s rainy season pushes rats and mice into warm crawlspaces, and their droppings, nesting material, and dander end up inside duct runs. Source removal with HEPA filtration is the only way to actually get it out.
- Returns pulling from unfinished basements and crawlspaces. A return duct that draws air through a dusty, damp crawlspace will keep delivering that air to every room in the house. We inspect those runs with a camera before we quote the job.
- Condensation inside insulated ducts in attics with poor ventilation. Seattle’s wet winters saturate attic air, and that moisture condenses inside duct insulation. We find these sections with moisture meters and replace them so mold doesn’t get a foothold.
- Flex duct crushed by homeowners, rodents, or old age. The flexible ductwork used in many Seattle remodel projects collapses over time, especially in tight spaces. A crushed run starves a room of airflow and leaves dust sitting in the collapsed section.

FAQs About Air Duct Cleaning in Seattle
Most Seattle homes need it every 3 to 5 years. That window tightens to 2 to 3 years for homes with pets, recent renovation work, or residents with severe allergies. It stretches to 5 to 7 years for a single person in a newer home with good filtration. If you’re not sure, we’ll put a camera in your ducts and show you exactly what’s in there before recommending anything. Call (737) 727-2314 for a free estimate.
Flat price for the whole system. We quote a single dollar figure that covers every supply and return vent, the air handler, and the blower motor, and we put it in writing before any work starts. Per-vent pricing is how homeowners in Seattle end up paying far more than the number on the flyer, and we refuse to operate that way.
Yes, every job includes before-and-after photos of your actual duct runs, taken with our inspection camera. You’ll see the supply and return ducts, the air handler area, and any spots we repaired or replaced. The Relay Standard makes this standard practice. If a company will not show you photos, the work probably wasn’t done properly.
NADCA (the National Air Duct Cleaners Association) sets the standard for source removal: agitate the debris, extract it under negative pressure, and clean the entire system. That is the method we run, and Seattle’s older crawlspace and attic ductwork makes it essential. A vacuum at the register does not meet the standard and leaves the debris inside.
Yes, dryer vent cleaning is one of our core services, and in Seattle’s damp climate a clogged dryer vent is both a fire risk and a moisture source inside the home. We clean the dryer transition, the vent run, and the termination point, and we verify airflow at the exterior vent before leaving. Call (737) 727-2314 and we’ll schedule both at once.
