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 DuPont, WA
Air duct cleaning in DuPont typically runs $450 – $900 for a standard single-family home, depending on square footage and how long it’s been since the last cleaning. We’re Cardinal Air Duct Cleaning, part of the Relay Home Co. family, and we work on homes across DuPont where the mix of early-2000s construction, mature landscaping, and damp Pacific Northwest air creates a specific set of duct conditions. Call (737) 727-2314 and you’ll get a written price before any work starts, not an estimate that shifts once we’re inside.
Why DuPont Homes Are Different
DuPont’s housing stock is younger than most Pierce County cities, but that doesn’t mean the ducts are clean. Homes in the Historic Village and Bell Hill date to the early 1900s and often have duct runs that were retrofitted into older framing, which means more joints, more turns, and more places for debris to collect. The larger subdivisions off Center Drive and McNeil Street, built in the 1990s and 2000s, share a different issue: long flex-duct runs through attics that trap construction dust from the original build, plus whatever the previous owners’ pets left behind.
The real factor here is moisture. DuPont sits close enough to Puget Sound that humidity runs high from October through April, and that damp air moves through return ducts every time the furnace kicks on. When dust inside the ducts absorbs that moisture, it cakes onto the duct walls instead of blowing through. A blower-door test or pressure check that looks fine in a drier climate can miss this entirely. We see it on Sequalitchew Creek trails and the neighborhoods around Edmonds Marsh, where homes are surrounded by vegetation that sheds pollen and fine organic matter into exterior vent intakes. Add in the fir needles and cedar dust from the mature evergreens around Hoffman Hill, and you get a duct system that looks clean at the register but is carrying a lot more than air.
Our Main DuPont Services
Most DuPont homeowners call us for one of three things: dryer vent cleaning, full air duct cleaning, or HVAC unit cleaning. Each has its own DuPont page with pricing and detail.
Dryer Vent Cleaning in DuPont
Dryer vents in DuPont clog faster than homeowners expect, especially in two-story homes where the dryer sits on the main floor and the vent runs up through the wall and out the roof. Every extra foot of vertical run gives lint more time to accumulate, and the humid air from Puget Sound makes that lint stick instead of blowing clear. We run a Rotobrush system through the full vent length, then verify airflow with a digital manometer at the exterior termination point. If you’ve noticed clothes taking two cycles to dry, the vent is telling you something. Read the full breakdown at Dryer Vent Cleaning in DuPont.
Air Duct Cleaning in DuPont
A full air duct cleaning in DuPont covers supply and return runs, the trunk lines, and the plenum, using a rotating brush to agitate debris and a Nikro HEPA vacuum running negative-pressure extraction, meaning the loosened dust goes into the vacuum, not back into your living room. We also clean the register covers and inspect accessible sections of ductwork for gaps or disconnects. Homes near the golf course off Palisade Boulevard pick up sand and turf particles that settle in low points of the ductwork. Details and pricing are on the Air Duct Cleaning in DuPont page.
HVAC Cleaning in DuPont
HVAC cleaning focuses on the equipment itself: the evaporator coil, blower wheel, condensate pan, and the cabinet interior. DuPont’s damp air means the coil rarely runs dry, and a wet coil traps every particle that passes through it. Over two or three years that becomes a mat of dust and biological growth that restricts airflow and cuts efficiency. We clean the blower assembly with a soft-bristle brush and compressed air, then treat the coil with an EPA-registered cleaner. Read specifics at HVAC Cleaning in DuPont.

In DuPont, the biggest price variables are access: attic duct runs in mid-2000s homes off Bob’s Hollow Lane are usually straightforward, but older conversions in the Historic Village can involve tight crawlspace work and longer hose runs. Whatever the number, it’s the number. Written, before we touch a single duct, and it does not change at the door.
