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.

AfterHow Much Does Air Duct Cleaning Cost in Seattle?
Air duct cleaning in Seattle typically costs between $450 and $1,100 for a standard single-family home, with most households landing near $650. That range covers a full supply-and-return cleaning for a house with one heating and cooling system and 10 to 20 vents. Larger homes, multi-system setups, and heavy buildup from Seattle’s damp climate push the number higher.
Kestrel Air Duct Cleaning offers a written price before any work begins, so the figure you’re quoted is the figure you pay. No door-step revisions, no surprise add-ons. Call (469) 972-3151 for a free estimate, and we’ll give you a real number based on your home, not a phone-book average.
Key Takeaways
- Most Seattle homes pay $450-$1,100 for full air duct cleaning.
- The average job runs about $650.
- Seattle’s wet, mild climate (and the pollen that follows it) makes duct buildup different from drier cities.
- Every Kestrel job includes a written price up front and the 365-Day Done Right Promise in writing.
Air Duct Cleaning Cost Breakdown (2026)
Here’s how the Seattle market breaks down line by line. These are real ranges based on what homeowners in the area actually pay, not national averages pulled from a database.
| Service Component | Typical Price Range | Notes |
|---|---|---|
| Base duct cleaning (1 system, up to 10 vents) | $450 - $650 | Supply and return lines, register-to-trunk |
| Additional vents (per vent) | $25 - $45 | Common in larger Seattle-area homes |
| Second HVAC system | $200 - $350 | Ductless mini-splits priced separately |
| Heavy debris or pest cleanup | $150 - $400 | Rodent nesting, construction dust, water damage |
| Dryer vent cleaning (add-on) | $125 - $225 | Roof or long-run vents cost more |
| Filtration / IAQ product install | $180 - $600 | Honeywell, Aprilaire, or Guardsman options |
A few things move the price up or down. The number of vents is the biggest lever. A 1,200-square-foot bungalow in Ballard with eight vents will price lower than a 3,200-square-foot house in Sammamish with two systems and 28 vents. Access matters too. Ducts buried behind finished walls or in a tight crawlspace take longer to reach and clean properly. If we find rodent debris, standing moisture, or a decade of dust, that’s a different job than routine cleaning, and we’ll tell you before we start, not after.
And here’s where the “cheap” quote falls apart. If someone offers $199 for a whole-house cleaning, the odds are good they’re using a shop vac and a leaf blower, or they’ll invent problems once they’re inside your home. Real equipment costs money to buy and maintain. We use Rotobrush rotary brush systems to dislodge debris at the duct wall, Nikro negative-pressure units to pull that debris out of the system, and Abatement Technologies HEPA filtration to keep loosened particles out of your living space while we work. That’s the difference between cleaning ducts and stirring dust around.
What Affects Air Duct Cleaning Pricing in Seattle
- Home size and vent count. More square footage means more duct runs and more vents. A 20-vent home can run $200 to $300 more than a 10-vent home.
- Number of HVAC systems. If you’ve got a furnace and a heat pump, or two separate zones, that’s two systems to clean. Each one adds $200 to $350.
- Seattle’s climate and what it leaves behind. Western Washington’s damp, mild winters mean ducts sit in humid air for months. That encourages mold and mildew growth in ways drier climates don’t see. The trade-off is dust, which Seattle’s long pollen season (roughly February through June) pushes into the system every spring.
- Age of the home and duct material. Older Seattle-area homes, especially those built before 1980, often have unsealed metal or flex duct with more buildup and more leaks. Newer construction dust and drywall debris also need a thorough first cleaning.
- Access and layout. Ducts in a finished basement, behind drywall, or in a low crawlspace take longer. Roof-run dryer vents are a separate increase.
- Condition of the system. Rodent activity, water intrusion, or years since the last cleaning all raise the price because the work is heavier.

How to Save on Air Duct Cleaning
There’s no magic discount, but a few smart moves keep the number down.
- Bundle duct cleaning with dryer vent cleaning. Since we’re already on site, the dryer vent add-on often runs lower than booking it as a standalone visit.
- Book before pollen season, not after. Late winter and early spring are slower for us. You’ll get your pick of arrival windows, and you won’t be cleaning out a season’s worth of pollen from scratch.
- Know your vent count. Count the supply and return registers in every room before you call. That single number tells us more about your price than anything else, and it keeps the quote accurate from the start.
- Ask about repeat service. If you’ve had us out before and nothing has changed, we don’t need to re-quote from zero. Just tell us it’s the same house.
- Skip the $99 special. It’s not a discount, it’s a hook. A written price from a company that shows up with real equipment will beat a cheap quote that turns into a $900 “you’ve got mold” conversation every time.
Free estimates are always free. Call (469) 972-3151 and get a written price in your hands before anyone touches a vent. That’s the Kestrel standard: say the price, show up in the window we gave, leave the place cleaner, put the guarantee in writing, come back if it fails. That’s The Kingswell Way, and it’s been our code since 2004.
FAQs - Air Duct Cleaning Cost
How much does air duct cleaning cost in Seattle?
Most Seattle homeowners pay between $450 and $1,100, with a typical job around $650. That’s for a single-system home with 10 to 20 vents. Homes with two HVAC systems or heavy buildup run $900 and up. Call (469) 972-3151 for an exact quote based on your house – estimates are free.
Is air duct cleaning worth it in Seattle’s climate?
Yes, and Seattle has a specific reason. The damp, mild air from October through April keeps ducts sitting in higher humidity than most U.S. cities, which encourages mildew growth and microbial buildup. Combined with the region’s heavy tree and grass pollen in spring, that’s a real load. For homes with allergy sufferers, pets, recent remodeling, or no cleaning in 5+ years, the difference is noticeable. Call (469) 972-3151 and we’ll tell you honestly whether your home needs it now or can wait.
Is it cheaper to clean ducts or replace them?
Cleaning is almost always cheaper. A full duct replacement in Seattle typically runs $3,500 to $8,000, versus $450 to $1,100 for cleaning. Replacing only makes sense when the ducts are crushed, badly damaged, or contaminated beyond cleaning, like after a major water event. We inspect and tell you which situation you’re in before quoting. Call (469) 972-3151 for a free inspection.
Can you come out the same day I call?
Often, yes, depending on the day and season. We answer the phone with a live person 24/7, not a voicemail queue, so you can get a real arrival window even if you’re calling tonight. Same-day and next-day slots open up more in the off-season. Call (469) 972-3151 and we’ll tell you what’s available today.
What’s included in the price?
Every Kestrel quote covers a full supply-and-return cleaning of all accessible ductwork, register-by-register agitation with a Rotobrush rotary brush system, negative-air extraction using Nikro equipment, and HEPA filtration with Abatement Technologies gear to keep dust out of your rooms while we work. You get a written price before we begin, a defined arrival window, and the 365-Day Done Right Promise in writing. If the work falls short within a year, we return and make it right at no charge. Call (469) 972-3151 to book or to ask what your specific home would cost.
Why Kestrel’s Pricing Works Differently
Plenty of homeowners in Seattle have a duct-cleaning story. The technician who said $299 on the phone and $899 at the door. The one who never showed up during the four-hour window. The dryer vent that clogged again six weeks later because someone ran a shop vac through it for five minutes.
We built Kestrel to be the accountable alternative, and the pricing reflects that. The written price is in your hands before a single vent is touched. No exceptions, no promotional loopholes. That commitment has been part of the Kingswell Guarantee since our founding in 2004, and it applies to every job, every time.
The crews are background-checked and uniformed. They show up in the arrival window we gave you, they lay down protection, and they leave the place cleaner than they found it. The 365-Day Done Right Promise is documented in writing on every job: if the work falls short within the year, we come back and make it right at no charge. Not a courtesy. Not a maybe. A written commitment.
If you want to maintain clean air between service visits, we install and stock Honeywell, Aprilaire, and Guardsman filtration and indoor-air-quality products. That way you’re not relying on duct cleaning alone to carry the load.
