Fast, Reliable Air Duct Cleaning Across Beaverton
Air duct cleaning in Beaverton typically runs $350–$650 for a full residential system and is usually completed in a single visit with same-day video inspection available. We’re familiar with the tight crawl spaces and aging flex ductwork that define homes from Murrayhill to Cooper Mountain, and we carry the right equipment for both. Call (877) 335-1974 for a free estimate — we answer until 8 p.m. most evenings.

Beaverton sits in the Tualatin Valley with a housing stock built largely during the Silicon Forest expansion of the 1980s and 1990s. That era’s tract construction favored flexible plastic ductwork routed through unconditioned crawl spaces and cramped attic chases — materials now 30 to 40 years old and showing their age in Washington County’s persistently damp climate. We’ve spent 11 years as a dedicated indoor air quality specialist, not a generalist HVAC company that added duct cleaning as an upsell, and our Air Duct Cleaning team has handled the specific failure patterns this combination creates.
Richard Anderson, our Owner and Lead Technician, personally oversees every job. That means direct owner accountability from the initial phone call through the final airflow test — a structure most multi-trade operations simply can’t match because their owners don’t run the equipment.
Why Landmark Air Duct Cleaning Service Washington Is Beaverton’s Preferred Air Duct Cleaning Company
Our reputation in Beaverton is built on 732 verified reviews averaging 4.9 stars — a volume that reflects hundreds of real homes across Washington County, not a handful of cherry-picked testimonials. Property managers in the Cedar Hills corridor and homeowners near Progress Ridge have left specific feedback about our thoroughness in tight-access crawl spaces, which matters when your duct runs sit 18 inches off a damp dirt floor.
Response time to Beaverton averages 45–60 minutes from dispatch for scheduled appointments, with same-day availability three out of five weekdays. We know the parking constraints around Beaverton’s denser townhome clusters and alley-load configurations — our van carries 150 feet of vacuum hose so we can often stage on the street and run line through side gates rather than block narrow driveways.
Local knowledge makes a measurable difference here. We understand that Beaverton’s west-side hillside homes in Cooper Mountain and Sexton Mountain were predominantly built with heat pumps rather than gas furnaces, meaning air circulates through ducts year-round in both heating and cooling modes. That continuous operation accelerates contamination buildup compared to furnace-only systems that sit idle from May through September — and it changes how we approach cleaning frequency and scope.
Our Air Duct Cleaning Services in Beaverton
Residential Duct Cleaning
Beaverton’s single-story and split-level tract homes — the dominant stock from the 1985–1995 build wave — present a specific challenge: original flex ductwork with micro-tears, sagging low points, and joints that have worked loose from decades of thermal cycling. Our residential service addresses the full supply and return network, not just the vents you can see. We use Rotobrush professional-grade cleaning systems with HEPA-contained debris removal, which matters in Beaverton’s tight crawl spaces where disturbance without containment would blow particulate through floor penetrations into living areas. A typical Beaverton residential cleaning runs $350–$550 for homes under 2,500 square feet.
Commercial Duct Cleaning
Beaverton’s commercial base spans medical offices near the Kaiser Westside campus, retail along Cedar Hills Boulevard, and professional services in the Murrayhill Town Center. These facilities face different contamination profiles than residences — higher occupancy loads, more frequent filter changes that mask underlying duct accumulation, and HVAC systems that run longer hours. Our commercial service scales to multi-zone systems and includes pre- and post-cleaning airflow measurement. We schedule around business hours to minimize disruption, and our Nikro equipment handles the larger trunk diameters common in commercial builds from the 1990s and 2000s.
Supply Duct Cleaning
Supply lines in Beaverton homes deliver conditioned air through flex runs that often sag in unconditioned attic chases, creating debris-trapping low points. In Murrayhill and Sexton Mountain subdivisions specifically, we’ve found supply ducts with 2–3 inch sags that hold years of accumulated dust against the duct wall — restricting airflow and creating humid pockets where mold establishes. Our supply duct service includes mechanical agitation with soft-bristle brushes sized for 6-inch and 8-inch flex, followed by negative-pressure extraction. We flag sagging sections for repair or re-support during the cleaning process.
Return Duct Cleaning
Return ducts draw unfiltered air from your living space back to the air handler, making them the primary collection point for larger particulate. In Beaverton’s older tract homes, return pathways are often framed cavities rather than dedicated metal or flex duct — wall and floor chases that accumulate construction debris from 1989 that no filter ever touched. Our return cleaning includes video inspection of these cavities where accessible, and we frequently find disconnected flex-to-trunk connections that have been pulling crawl space air into the system for years. Repair and sealing is available as a follow-on service.
Full System Cleaning
This is our most comprehensive Beaverton service, covering supply ducts, return ducts, the air handler cabinet, blower assembly, and coil surface where accessible. Given Beaverton’s heat-pump prevalence, the coil stays active in both heating and cooling seasons — and a contaminated coil recirculates debris into clean ducts within days. Full system cleaning starts at $550 for typical Beaverton homes and includes before-and-after video documentation. We recommend this service for first-time customers who haven’t had ductwork addressed in 10-plus years.

Video Inspection
Our video inspection service uses a self-leveling camera head on a flexible rod, fed through existing duct openings without cutting access panels. In Beaverton’s aging flex duct systems, this reveals what homeowners can’t see: disconnected joints three feet inside a crawl space wall, mold staining on the interior duct surface, sagging runs with standing water, and construction debris from the original 1989 build. We record findings and review them with you on-site. Video inspection alone runs $150–$225, or it’s included with any full cleaning service.

Trusted Brands We Service in Beaverton
We clean duct systems connected to all major HVAC equipment brands, and we stock air quality upgrade components from Honeywell, Aprilaire, and Abatement Technologies for Beaverton customers who want to address contamination at the source. Our Rotobrush and Nikro cleaning systems are the same professional-grade units used by commercial restoration contractors — not rental-grade equipment that lacks the suction power for deep flex duct cleaning. For homes with persistent microbial concerns after cleaning, we offer Guardsman-applied sanitizing treatments that target residual mold and bacteria without the residue issues of consumer-grade fogging products. Parts and upgrade components are typically available without extended shipping delays, keeping project timelines predictable for Beaverton homeowners and property managers.
Common Air Duct Cleaning Problems We See in Beaverton Homes
- Flex duct sagging in tight attic chases — The 1980s–1990s tract homes in Murrayhill and Cooper Mountain were built with 6-inch flex duct jammed into 2×10 joist bays with minimal support. Over decades, the wire helix relaxes and the duct sags between straps, creating low points that trap dust, pollen, and moisture against the duct wall. Airflow drops. Mold follows.
- Disconnected joints in unconditioned crawl spaces — Thermal expansion and contraction, plus rodent activity common in Washington County’s wooded lots, loosen flex-to-trunk connections. Conditioned air escapes into the crawl space. Energy bills rise. Worse, the negative pressure draws humid outside air and crawl space particulate into the return side.
- Moisture wicking from inadequate vapor barriers — Beaverton’s 37 inches of annual rainfall and high water table mean ground moisture penetrates crawl spaces without proper subfloor vapor barriers. That moisture condenses on the cool interior surface of flex ducts during shoulder seasons, creating the damp conditions mold needs. We’ve confirmed active growth in ducts where homeowners reported no visible symptoms.
- Year-round heat pump circulation accelerating buildup — Unlike gas furnace systems that idle all summer, Beaverton’s heat-pump-equipped homes move air through ducts continuously. Fine Tualatin Valley clay dust — distinctive to this valley’s soil composition — and mold spores circulate in every season, coating duct interiors faster than in furnace-only markets.

What moves you within these ranges? Home size and duct run length are the basics. But in Beaverton, the bigger variables are access difficulty — how tight is your crawl space, how far from the driveway can we stage — and the condition of the existing ductwork. A home with intact, well-supported flex duct cleans faster than one with multiple sags, disconnections, and debris-packed low points that need mechanical agitation and repeated passes. We assess this during our free estimate visit, and we quote upfront before starting work. No open-ended hourly billing.
We serviced a split-level home on Murrayhill Drive where the original flex duct runs through an unconditioned crawl space had disconnected at the main trunk, blasting fine Tualatin Valley clay dust into every room. Using our Rotobrush system and video inspection, we cleared the debris and resealed the joints, restoring airflow. The job ran toward the higher end of our residential range because of the repair component — but the homeowner knew the exact cost before we started.

FAQs — Air Duct Cleaning in Beaverton
Flexible plastic ductwork has a porous interior surface and wire-helix construction that creates microscopic crevices where moisture collects, unlike smooth metal duct that sheds condensation. In Beaverton’s damp maritime climate — particularly in crawl spaces without adequate vapor barriers — this material difference becomes critical: we’ve confirmed active mold in flex ducts where adjacent metal trunk lines remain clean. The age factor compounds this, as 30–40-year-old flex duct has degraded and micro-torn, opening more surface area for colonization. Call (877) 335-1974 if you suspect mold in your system — we include visual and video assessment with every estimate.
Yes — in fact, Beaverton’s heat-pump-prevalent west-side homes often need more frequent cleaning than furnace-only systems. Heat pumps circulate air through ducts in both heating and cooling modes year-round, whereas a gas furnace sits idle from late spring through early fall. That continuous operation in Beaverton means Tualatin Valley clay dust, pollen, and mold spones never get a seasonal break from circulation. We typically recommend cleaning every 3–4 years for heat-pump homes versus 5–7 for furnace-only systems in comparable conditions. Call (877) 335-1974 and we’ll assess your specific system runtime and contamination level.
Minimal impact on our end — we carry 150 feet of vacuum hose and compact Rotobrush units specifically for tight-access Beaverton properties, including alley-load townhomes near Progress Ridge and dense clusters off Hall Boulevard. Our van stages on the street or in designated guest parking, and we run line through side gates or ground-floor utility entries. The only constraint is crawl space headroom below 18 inches, which may limit technician access to certain duct runs; we’ll verify this during your free estimate and note any sections that require alternative approaches. Call (877) 335-1974 to schedule an access assessment.
A video inspection reveals the actual condition inside your ducts: disconnected joints hidden behind crawl space walls, sagging low points with accumulated debris, mold staining on the interior surface, and construction debris from the original 1980s–1990s build that has never been removed. In Beaverton specifically, we frequently find thermal deterioration of flex duct insulation, where the vapor barrier has cracked and the fiberglass layer is exposed to crawl space humidity. This isn’t visible from the vent register — only a camera inside the duct shows it. Video inspection is included with full system cleaning or available standalone; call (877) 335-1974 to book.
Every 3–5 years for most Beaverton homes with crawl-space flex duct, and every 3 years if your system includes a heat pump or shows any history of moisture intrusion. The combination of unconditioned crawl space exposure, Washington County humidity, and aging duct materials creates faster contamination accumulation than in drier climates or homes with basement-mounted metal ductwork. Homes in Cooper Mountain and Sexton Mountain with hillside drainage issues may need more frequent assessment — we check for standing water or vapor barrier failure during every cleaning. Call (877) 335-1974 for a free evaluation of your specific conditions and a recommended schedule.
