Our Air Duct Cleaning Services in Five Corners
Residential Duct Cleaning in Five Corners
Five Corners’s 1970s–1990s ranch and split-level homes were built during Clark County’s explosive growth as a Portland bedroom community, and most still run on original flex-duct systems that have never been professionally cleaned. Our residential service targets the exact failure modes we see here: sagged low points holding wet debris, mold colonies seeded during the October–April sealed season, and fine ash particulate from late-summer wildfire events. A typical full residential cleaning in Five Corners runs $450–$650 for a 1,500–2,500 square foot home with 12–20 vents.
Commercial Duct Cleaning in Five Corners
The small commercial strip along NE Highway 99 and the professional offices near the Five Corners intersection itself rely on HVAC systems that pull from the same damp Clark County air as residential properties. We clean commercial ductwork in Five Corners retail and office spaces with the same Rotobrush and Nikro systems scaled to larger trunk lines, scheduling around your business hours to avoid disrupting operations. Commercial pricing in Five Corners typically starts at $800 for systems under 5,000 square feet.
Supply Duct Cleaning in Five Corners
Supply runs in Five Corners homes face a unique stress: the Pacific Northwest’s wet season drives moisture into crawl-space flex-duct, and when that damp debris sits in sagged low points, it restricts airflow to the rooms farthest from the furnace. We isolate and clean each supply branch individually, using compressed air whips and vacuum extraction to clear the pooled material that standard brush systems miss. Supply-only cleaning in Five Corners runs $250–$400 depending on branch count and access difficulty.
Return Duct Cleaning in Five Corners
Return-air systems in Five Corners are the entry point for both winter mold spores and late-summer wildfire smoke — they’re the lungs of your house, and they’re often the dirtiest component we find. In a 1983 ranch on NE 99th Street, we opened a crawl-space access panel to find original sagged flex-duct runs that had collected a dark slurry of dust, moisture, and ash from last summer’s wildfire season. Using our Rotobrush system, we vacuumed out the pooled debris and sanitized the duct interior, then installed new support straps to prevent re-sagging. Return-duct cleaning in Five Corners typically adds $150–$250 to a full system service.
Full System Cleaning in Five Corners
This is our most requested service in the 98662 ZIP, and for good reason. A full system cleaning addresses supply branches, return trunks, the main plenum, and register boots — the complete airflow path. In Five Corners’s older homes, this often reveals cross-contamination between damp crawl-space sections and living areas that homeowners never suspected. Full system cleaning runs $550–$750 in Five Corners, with video inspection included.
Video Inspection in Five Corners
Our video inspection service uses push-camera technology to document the internal condition of duct runs that are otherwise inaccessible — critical in Five Corners homes with limited original access panels. We record sag locations, debris accumulation points, and mold growth, then review the footage with you before recommending cleaning versus repair. Video inspection alone is $150–$200, waived with any full system cleaning.

Trusted Brands We Service in Five Corners
We don’t just clean ducts — we maintain and upgrade the air quality ecosystem they connect to. In Five Corners homes, we regularly install and service Aprilaire whole-home air purifiers and Abatement Technologies HEPA filtration systems that address the specific two-season contamination cycle here: winter mold from sealed-in moisture and late-summer fine ash from Columbia Gorge wind events. Our Rotobrush and Nikro cleaning equipment is the same professional-grade systems used by restoration contractors, not rental-store alternatives, and we stock Guardsman sanitizing treatments formulated for the organic debris we find in Pacific Northwest crawl spaces. That means no waiting on parts when your Five Corners home needs immediate attention after a wildfire smoke event.
Common Air Duct Cleaning Problems We See in Five Corners Homes
- Sagged flex-duct low points pooling wet debris. Five Corners sits at the heart of Clark County’s 1980s suburban boom corridor, where dense tracts of ranch and split-level homes were built with flex-duct HVAC systems that are now 35–45 years old and largely unserviced. The combination of Western Washington’s long damp-and-sealed heating season with increasingly severe late-summer wildfire smoke events from the Cascades and eastern Oregon creates a two-season contamination cycle — mold moisture in winter, fine ash particulate in August–September — that makes duct cleaning a genuine health need here, not an upsell.
- Limited access panels preventing thorough cleaning. The 98662 ZIP covering Five Corners is dominated by 1970s–1990s tract homes built during Clark County’s rapid expansion; a large share retain original flex-duct runs in unconditioned crawl spaces, with limited access panels that complicate thorough cleaning. We often need to cut additional access points to reach sagged low points — something generalist HVAC companies rarely bother with.
- Wildfire smoke infiltration in return-air systems. Late-summer Columbia Gorge wind events carry wildfire smoke and fine ash from eastern Oregon and Washington directly into return-air systems before homeowners think to close windows. We’ve cleaned Five Corners ducts in September that contained measurable ash layers from fires 200 miles away — contamination that standard furnace filters never catch.
- Mold colonies from October–April sealed-season moisture. The Pacific Northwest’s wet season means homes are sealed tight for months, allowing moisture to infiltrate sagging flex-duct low points in damp crawl spaces and seed mold colonies. Technicians working Five Corners crawl spaces routinely find flex-duct runs that have sagged between floor joists over decades, pooling wet debris and mold near the low points — a failure mode driven by the combination of 40-year-old unsupported flex duct and the persistently damp Clark County crawl space environment that would not be nearly as common in the drier Portland suburbs just across the Columbia.

What moves your Five Corners job within these ranges? Vent count is the biggest factor — a 1980s split-level with 14 vents runs very differently than a sprawling ranch with 28. Crawl-space accessibility matters too; homes near Five Corners Park with tight 18-inch clearances take longer than properties with full-height basements. Additional access panel cutting adds $75–$150 per location. Mold remediation beyond standard cleaning runs $200–$400 depending on colony extent. We provide exact quotes before starting any work — call (877) 335-1974 for your free estimate.

FAQs — Air Duct Cleaning in Five Corners
The persistently damp Clark County crawl space environment means debris in Five Corners ducts is often wet and adhered, not loose dust that vacuums out easily. Our Rotobrush system uses aggressive bristle contact and simultaneous vacuum extraction to dislodge this material, and we frequently need to address mold remediation alongside standard cleaning. Call (877) 335-1974 and we’ll assess whether your crawl space needs pre-drying or dehumidification before duct work begins — estimates are free.
Yes — our push-camera video inspection is specifically designed to locate sag points, debris pools, and structural deterioration in flex-duct runs that are otherwise invisible. In Five Corners’s 1980s housing stock, we find sagging in roughly 60% of homes we inspect, and the footage lets us show you exactly where support straps or duct replacement are needed. Video inspection is included with every full system cleaning, or available standalone for $150–$200.
Yes — late-summer Columbia Gorge wind patterns drive fine ash particulate directly into Five Corners return-air systems, and standard 1-inch furnace filters capture less than 20% of particles under 2.5 microns. We recommend full system cleaning within 2–4 weeks of major smoke events, with HEPA-level filtration upgrade if your home has sensitive occupants. Call (877) 335-1974 for priority scheduling during wildfire season — we maintain extended hours in August and September.
That odor is almost always active mold growth in sagged flex-duct low points where October–April moisture has pooled undisturbed. Five Corners’s combination of 40-year-old unsupported duct and damp crawl spaces creates perfect mold conditions that don’t dry out until May. Standard cleaning removes the colonies; adding Aprilaire or Abatement Technologies filtration prevents re-seeding. Call (877) 335-1974 — musty odors mean active biological growth, not just old dust.
Most 1980s flex-duct in Five Corners can be cleaned effectively if the inner liner is intact and sags are less than 6 inches deep — we restore airflow and install support straps to prevent re-sagging. Replacement becomes necessary when the liner is torn (common at joint tape failures), sag depth exceeds 12 inches creating permanent water traps, or mold has penetrated the insulation layer. We give honest repair-vs-retrofit guidance with video evidence; call (877) 335-1974 for inspection and exact options.
