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.

AfterAir Duct Cleaning Company in SeaTac, WA
Cardinal Air Duct Cleaning is the air duct specialist serving SeaTac, WA, with three focused services: Air Duct Cleaning in SeaTac, HVAC Cleaning in SeaTac, and Dryer Vent Cleaning in SeaTac. What makes SeaTac jobs different comes down to what surrounds every home here: aircraft activity, road dust from Highway 99 and International Boulevard, and housing stock that ranges from 1960s ramblers to newer townhome developments near Angle Lake. That mix means no two duct systems in SeaTac carry the same load, and no two quotes should look the same either. Call (737) 727-2314 for a written price before any work begins.
Why SeaTac Homes Are Different
SeaTac sits directly under one of the busiest flight paths in the Pacific Northwest, and that single fact reshapes how we approach every duct cleaning job here. Homes in McMicken Heights, Bow Lake, and the residential pockets off Des Moines Memorial Drive accumulate a finer, more persistent particulate load than homes even a mile away. Aircraft exhaust residue, tire dust from the airport access roads, and the general churn of passenger and freight traffic settle into return registers and get pulled through the system every time the blower kicks on.
Older SeaTac homes, particularly the mid-century stock near Angle Lake and along 188th Street, often have duct runs that were never sealed to modern standards. That means the system pulls attic air, crawlspace air, and whatever is trapped in wall cavities along with the conditioned air. Newer construction in the city carries a different issue: tighter building envelopes that trap the same particulates indoors longer. We adjust our approach, not our price formula, based on what the home actually presents at the walkthrough.
Humidity is the quiet factor too. SeaTac’s wet winters mean ducts that hold condensation longer, which is exactly when dust stops being dust and starts being sludge. We run HEPA-filtered negative-pressure extraction, which pulls loosened debris into a sealed vacuum rather than pushing it around the home, on every SeaTac job.
Our Main SeaTac Services
SeaTac homeowners call us for three things most often, and each has its own dedicated page with local pricing and setup details.
Dryer Vent Cleaning in SeaTac
Lint buildup in dryer exhaust lines is a fire risk, not a nuisance, and SeaTac’s damp winters make lint cling to vent walls faster than it dries. Our Dryer Vent Cleaning in SeaTac page covers how we clear the full run from dryer to exterior vent using a Nikro HEPA vacuum, and why vent length and bends matter more in older SeaTac homes with long, angled runs. Every job includes a written price before we touch the line.
Air Duct Cleaning in SeaTac
SeaTac’s air quality demands a deeper clean than most cities. Our Air Duct Cleaning in SeaTac service uses Rotobrush rotary agitation combined with negative-pressure extraction, which means we loosen and remove, not just vacuum. That matters when the particulate is fine and sticky, as it is near the airport. The page includes honest whole-system pricing and the 365-Day Done Right Promise details.
HVAC Cleaning in SeaTac
Your HVAC system moves air through your ducts, and dirty components undo a clean duct run within weeks. Our HVAC Cleaning in SeaTac service covers blower motors, coils, and drain pans using Abatement Technologies containment where needed. For SeaTac homeowners with older furnaces, that condensate line flush and coil cleaning matters more than anywhere else in the county.

What pushes a SeaTac quote toward the upper end is usually the same thing that makes the job worth doing: long duct runs in split-level homes, excessive particulate from nearby airport traffic, or a system that hasn’t been opened in years. Every quote we hand over is a written price for the whole system, agreed before work starts. It does not change at the door.

Most SeaTac jobs are scheduled within 3 to 5 business days, depending on what the home needs and how many systems are involved. Call (737) 727-2314 and a live person will give you available windows right then.
Duct cleaning is interior work, so no city permit is required in SeaTac and HOAs typically have nothing to say about it. If your condo or townhome association needs proof of insurance or a scope of work before we arrive, we can provide both, and the written price we hand you covers exactly what we will do.
Yes. Homes closer to International Boulevard and the airport approaches carry a higher fine-particulate load in their returns and duct walls than homes further south or east. We see it on every job walkthrough near the flight path, and it is the main reason we run HEPA negative-pressure extraction as standard on SeaTac homes.
Calling is fastest. A live person answers around the clock, and you will get a booking link with a trackable arrival window, before-and-after photo documentation, and a digital invoice you can pay from your phone. That is The Relay Standard, and it applies to every SeaTac booking.
