We’ve been pulling debris from Kent ductwork for 11 years, and the valley floor here tells a different story than the hillside cities around it. Our Air Duct Cleaning team knows the difference between a standard dust load and the soot-heavy buildup we find near the SR-167 corridor. Richard Anderson, our owner and lead technician, personally oversees every Kent job—from the 1970s ranches near Kent Kangley Road to the newer construction up toward Covington. Call (877) 335-1974 for a free estimate and we’ll give you an honest read on what your system actually needs.
Why Landmark Air Duct Cleaning Service Washington Is Kent’s Preferred Air Duct Cleaning Company
Kent homeowners have left us 732 verified reviews averaging 4.9 stars, and a significant share of those come from repeat customers across the 98032, 98035, and 98042 ZIP codes. They mention specifics: Richard showed up on time, explained what he found in the video inspection, and didn’t push services the ductwork didn’t need.
That direct owner accountability is structural, not marketing. Richard Anderson doesn’t delegate to rotating crews—he runs the Rotobrush and Nikro equipment himself, interprets the video feed himself, and signs off on every job. For property managers overseeing multiple units near the Kent Station development or along Central Avenue, that means one consistent point of contact who remembers your buildings from the last visit.
Our response time to Kent averages under 36 hours for standard bookings, with emergency slots available when indoor air quality issues can’t wait. We know which Kent neighborhoods sit in the valley’s persistent fog layer, where moisture problems in ductwork accelerate fastest, and we schedule accordingly.
Our Air Duct Cleaning Services in Kent
Residential Duct Cleaning
Kent’s housing stock skews heavily toward 1970s–1990s construction, especially in east Kent (98042) and the older central areas. These homes often run original flex ductwork or uninsulated sheet-metal runs that predate modern sealing standards—meaning gaps pull in attic insulation fibers and crawl-space debris that bypass your filter entirely. Our residential cleaning addresses the full supply and return network, not just what’s visible at the registers. A typical Kent home runs $350–$650 depending on system size and accessibility.
Commercial Duct Cleaning
Kent’s warehouse and distribution density creates unique commercial demands. Facilities near the SR-167 corridor process enormous air volumes in buildings that operate 18–20 hours daily, loading ductwork with particulate at rates that outpace standard maintenance schedules. We scale our Nikro vacuum systems and Rotobrush agitation tools for commercial square footage, working around operational hours to minimize disruption. Commercial quotes start at $800 and scale with system complexity.
Supply Duct Cleaning
Supply ducts deliver conditioned air to your rooms—and in Kent, they often deliver more than intended. The valley’s trapped diesel particulate infiltrates through envelope leaks, then concentrates in supply runs where pressure dynamics are highest. We isolate and clean each supply branch individually, checking for insulation fiber accumulation at the boot connections common in pre-1990s Kent construction. Supply-only cleaning runs $200–$400 when paired with a full system assessment.
Return Duct Cleaning
Return ducts pull air back to your HVAC unit, making them the primary collection point for airborne debris. In Kent’s low-lying neighborhoods, returns in 98032 and 98031 regularly show heavier soot loading than comparable homes in elevated Auburn or Renton. We clean the full return path including the plenum and filter rack, checking for moisture staining that signals the mold-friendly conditions this valley’s fog layer creates.
Full System Cleaning
This is our most requested service in Kent for good reason. A full system cleaning covers supply ducts, return ducts, the main trunk line, plenums, and accessible coil surfaces—addressing the complete airflow path where valley-floor particulate and moisture interact. For homes with 30–50-year-old ductwork that has never been professionally cleaned, this is often the only approach that restores design airflow. Full system cleaning in Kent ranges from $450–$750 for typical residential layouts.

Video Inspection
Our video inspection service gives Kent homeowners and property managers documentary evidence of what sits inside their ductwork. The flexible borescope feeds through access points, revealing insulation gaps, moisture staining, soot accumulation, and structural deterioration in real time. In 98032 homes near the logistics corridor, we’ve captured footage of duct interiors coated with fine black particulate that homeowners initially mistake for mold—it’s diesel soot, and it requires different remediation. Video inspection is included with full system cleaning or available standalone at $150–$250.

Trusted Brands We Service in Kent
We run professional-grade Rotobrush agitation systems and Nikro HEPA-filtered vacuums—the same equipment specification used by commercial restoration contractors, not rental-grade alternatives. For air quality upgrades following cleaning, we work with Honeywell, Aprilaire, Abatement Technologies, and Guardsman product lines, stocking common filter sizes and UV-C lamp configurations for faster turnaround on Kent jobs. When a 98042 homeowner needs an Aprilaire media upgrade or a Guardsman sanitizing treatment following mold remediation, we don’t special-order and make you wait—we carry the hardware.
Common Air Duct Cleaning Problems We See in Kent Homes
- Attic insulation fibers in supply registers. Gaps in pre-1990s flex ductwork draw in loose-fill insulation every time the blower cycles. Kent’s older tract homes are full of this—homeowners notice white or gray fuzz collecting on vent louvers that no amount of surface cleaning fixes.
- Mold and biofilm in intermittently used systems. Kent’s 40+ inches of annual rainfall and persistent valley fog keep baseline humidity high. HVAC systems that don’t run consistently—weekend homes, guest wings, basement apartments—allow moisture to linger between cycles. The result is biofilm growth on duct interiors that standard dust removal won’t touch.
- Heavy soot accumulation from SR-167 truck traffic. Homes in 98032 and 98031 near the logistics corridor show visibly darker filter and duct debris than hillside neighborhoods. This isn’t ordinary household dust—it’s fine particulate from diesel combustion that embeds in duct surfaces and re-enters living spaces.
- Collapsed or deteriorated flex duct in crawl spaces. Kent’s older homes often run original flex duct through damp crawl spaces where sagging, rodent damage, and compression reduce airflow to distant rooms. We document this during video inspection and can coordinate repair and sealing through our full service range.

FAQs — Air Duct Cleaning in Kent
Most Kent homeowners should clean every 2–3 years rather than the regional 3–5 year standard, because the Green River Valley traps diesel particulate and moisture that accelerate buildup. The valley’s persistent fog and pooling marine air keep indoor humidity elevated, promoting mold and biofilm growth in intermittently used systems. Call (877) 335-1974 and we’ll assess whether your home’s location and usage pattern warrants the shorter interval.
Yes—our video inspection clearly shows the dark, uniform coating characteristic of diesel particulate accumulation, distinct from the patchier, lighter pattern of ordinary household dust. In 98032 homes near the SR-167 corridor, this soot layer is often visible within the first ten feet of ductwork from the return plenum. The footage gives you documentary evidence and helps us specify the right cleaning intensity. Call for a free video assessment.
Yes, we regularly clean original 1980s flex duct and uninsulated sheet-metal systems in 98042 and surrounding east Kent neighborhoods. We cleaned the ductwork of a 1980s tract home near East Hill Park in 98042, finding original uninsulated sheet-metal runs with biofilm from persistent valley fog. Using Rotobrush agitation and a HEPA-filtered Abatement Technologies vacuum, we removed fine black soot and mold spores, restoring airflow to design specs. Older ductwork requires gentler agitation settings and careful access point selection, which is why owner-led technician oversight matters. Call (877) 335-1974 to discuss your specific system.
We use Rotobrush agitation systems on nearly all residential Kent jobs, paired with Nikro HEPA-filtered vacuums for debris extraction. For heavily contaminated commercial systems or fragile vintage ductwork, we may adjust brush stiffness or supplement with compressed-air whipping tools. Richard Anderson selects the specific configuration based on what video inspection reveals—never a one-size-fits-all approach. Call to ask about the right method for your ductwork type.
Yes—homes closest to the Green River and its tributary lowlands experience the highest humidity exposure in Kent, accelerating mold and biofilm growth inside ductwork. These properties often need more thorough coil and plenum attention, and we pay particular attention to moisture staining patterns that indicate envelope leakage drawing in river-valley air. The particulate load is also distinct: less diesel soot than the 98032 corridor, more organic debris from riparian vegetation and seasonal pollen. Our assessment adjusts for these local factors. Call (877) 335-1974 for a free estimate tailored to your location.
