Fast, Reliable Air Duct Cleaning Across North Portland
Air duct cleaning in North Portland typically runs $350-$650 for a full residential system, with most jobs completed in a single visit. We’re usually on-site within the same day you call, and every job starts with a camera inspection so you see exactly what we’re dealing with before a single tool is lifted.
We’ve been driving our vans up to North Portland since 1984, long before the Mississippi Avenue corridor became what it is now. We know the tight parking on Albina’s side streets, the narrow crawl-space hatches in St. Johns foursquares, and the particular headache of alley-load access in Kenton’s older blocks. Our technicians carry compact Rotobrush and Nikro rigs built for exactly these constraints - not the trailer-mounted systems that need a driveway and three hours to set up. When you live in a 1920s bungalow with a crawl space you can barely stand in, that matters. Call us at (844) 685-6342 and we’ll give you a straight answer about what your system needs and what it’ll cost.
Why Bellows Air Duct & Vent Co. Is North Portland’s Preferred Air Duct Cleaning Company
North Portland’s 97203 occupies a low-lying peninsula flanked by the Willamette River to the east and the Columbia Slough to the north, creating a persistently humid microclimate that accelerates mold and mildew colonization inside ductwork far more aggressively than higher-elevation Portland neighborhoods. The neighborhood’s dense stock of pre-WWII craftsman bungalows and foursquares - many originally heated by gravity ‘octopus’ furnaces - had forced-air ductwork retrofitted piecemeal over subsequent decades, leaving duct systems that are often irregular, poorly sealed, and drawing crawl-space air saturated by the Slough’s elevated water table. This isn’t theoretical for us. In a St. Johns craftsman bungalow off Lombard, we opened a retrofitted trunk line and found corroded galvanized seams spliced into flex duct, pulling damp crawl-space air saturated by the Slough. We sealed every joint with mastic, cleaned the Rotobrush head twice mid-run, and installed an Aprilaire filter to break the moisture cycle.
We’ve built our reputation in North Portland on showing up when we say we will and leaving systems that stay clean. Our Air Duct Cleaning team answers calls live, 24 hours a day - not a voicemail, not an app. Background-checked, uniformed technicians arrive with camera equipment already rolling, and our 90-Day Done Right Promise means if something’s not right, we return at no charge with no paperwork required. Ray Castillo has run this company since its founding, and the K.E.Y.S. values code still governs every dispatch.
Homeowners in Kenton and St. Johns call us back because the price on the phone matches the price on the invoice. No bait coupons. No scare tactics. No price changes at the door. That’s been our practice for over 42 years.
Our Air Duct Cleaning Services in North Portland
Residential Duct Cleaning
North Portland’s 97203 is dominated by 1910s-1940s craftsman bungalows and foursquares that were never designed for forced-air systems. Retrofit duct runs are common, frequently mixing original galvanized sheet metal with later-added flex duct in tight crawl spaces, creating seam gaps and debris traps that standard cleaning equipment must navigate carefully. Our technicians assess each run individually - what’s metal, what’s flex, where the splice points are - before selecting brush diameter and vacuum pull. A typical residential duct cleaning in North Portland runs $350-$550 for a single-system home, with multi-zone or heavily contaminated systems reaching $650.
Commercial Duct Cleaning
The commercial corridors along Lombard Street and Interstate Avenue serve a mix of vintage storefronts, light industrial spaces, and newer infill. Older buildings often share the same retrofit problems as residential stock: piecemeal duct additions, inadequate access panels, and accumulation from decades of operation. We scope the system first, identify where cleaning ports need to be cut, and restore them afterward. Commercial jobs in North Portland typically start at $800 and scale with system complexity.
Supply Duct Cleaning
Supply ducts in North Portland homes face a specific challenge: crawl-space humidity wicks into supply ducts through unsealed retrofits, causing biological regrowth within weeks unless cleaning is combined with moisture-proofing and sealing. We don’t just brush and vacuum. We camera-verify that supply trunks are intact, seal accessible joints with mastic, and note where structural repairs may be needed. Supply-only cleaning runs $250-$400 in this market.
Return Duct Cleaning
Return pathways in older North Portland homes often pull through wall cavities and under-floor channels that were never intended as ductwork. These accumulate the most debris because they’re the intake point, and they’re hardest to access. Our Nikro portable systems fit where truck-mounted rigs cannot, and we disassemble register boots when necessary to reach the full return path. Return duct cleaning in North Portland typically costs $200-$350.
Full System Cleaning
This is what most North Portland homes actually need. Full system cleaning covers supply and return trunks, branch lines, register boots, and the air handler cabinet, with camera documentation before and after. Given the retrofit complexity common to 97203, we almost always recommend this level of service. Expect $450-$650 for a complete residential system.
Video Inspection
Every Bellows job includes video inspection - it’s non-negotiable. In North Portland, this is particularly valuable because the camera reveals corroded seam gaps, flex duct collapses, and moisture staining that visual inspection from a register cannot. We record the full length of accessible ductwork and review findings with you before proceeding. Standalone video inspection for diagnostic purposes runs $150-$250.

Trusted Brands We Service in North Portland
We run professional-grade equipment from Rotobrush, Nikro, and Aprilaire - the same brands serious HVAC contractors specify when they’re installing systems meant to last. Our vans stock Honeywell media filters and Aprilaire humidistat controls so we can address moisture problems at the source, not just treat symptoms. For North Portland homeowners, this means faster turnaround: when we find a failed component during cleaning, we don’t need to order parts and return next week. We fix it then, or we tell you exactly what it needs and when we can have it done.
Common Air Duct Cleaning Problems We See in North Portland Homes
- Corroded seam gaps in 1950s-60s galvanized trunk lines pull damp crawl-space air into living areas. Standard cleaning brushes right past these gaps. We locate them with the camera, seal with mastic, and verify the seal holds before we leave. Without this step, you’re paying to clean ducts that recontaminate within weeks.
- Flex duct additions spliced into original metal runs create debris traps that standard vacuum agitation cannot reach. The transition points between rigid metal and flexible duct are where particulate matter packs tightest. We disassemble these junctions where accessible, clean each segment independently, and reinstall with proper support to prevent future sagging.
- Crawl-space humidity wicks into supply ducts through unsealed retrofits, causing biological regrowth within weeks. Portland’s rainy season runs roughly October through May, and North Portland’s low elevation adjacent to the Columbia Slough compounds ambient ground moisture. Cleaning alone won’t solve this. We identify the moisture pathway and recommend sealing or dehumidification strategies alongside the mechanical clean.
- Tight crawl spaces under craftsman foursquares limit equipment access and technician maneuverability. Our compact Rotobrush and Nikro portables are built for this. We’ve cleaned ducts in crawl spaces under three feet high where standard equipment simply wouldn’t fit. If we can’t access it, we’ll tell you upfront and discuss alternatives - never pretend we can do work we can’t complete properly.
Pricing for Air Duct Cleaning in North Portland, OR

FAQs - Air Duct Cleaning in North Portland
Yes, the persistent humidity from the Columbia Slough and Willamette River accelerates mold and mildew growth in ductwork compared to higher-elevation Portland neighborhoods. Most North Portland homeowners benefit from cleaning every 3-4 years rather than the standard 5-year interval, especially if their home has unsealed retrofit ductwork. Call (844) 685-6342 and we’ll assess your specific moisture exposure.
Yes, we regularly work in St. Johns homes with this exact history. The original gravity furnace is long gone, but the retrofit ductwork it left behind requires careful navigation - irregular trunk sizing, mixed materials, and tight clearances. Our compact equipment and camera-guided approach handle these constraints. We’ll tell you before we start if any section is inaccessible.
Yes, duct sealing is available and often necessary in North Portland. We seal accessible joints with mastic and metal-backed tape, and we camera-verify the work. For comprehensive crawl-space moisture control, we coordinate with specialized contractors or can refer you to trusted partners we’ve worked with in 97203 for decades. Sealing typically adds $400-$900 to a cleaning job.
We use portable Nikro and Rotobrush equipment designed for confined access, and our technicians are trained to work efficiently in spaces under three feet high. If a section is genuinely unreachable, we document it with the camera and discuss alternatives - extended reach tools, register-boot disassembly, or in rare cases, access panel installation. We don’t charge for work we can’t complete properly.
Yes, if the smell originates from accumulated biological growth in the ductwork itself. However, if the root cause is ongoing moisture intrusion from unsealed crawl-space connections, cleaning alone will provide temporary relief at best. We camera-inspect to distinguish between contamination and moisture pathway problems, and we recommend sealing when needed so the smell doesn’t return next winter. Call (844) 685-6342 for a free estimate - we’ll tell you which situation you’re facing.
