We’re not strangers to St. Johns. We’ve pulled decades of compacted debris from galvanized trunk lines that predate the Voodoo Doughnut era, and we’ve traced mold blooms back to crawl spaces breathing damp air off the Columbia Slough. North Portland’s geography makes this work different from the drier east side or the west hills. We show up with equipment sized for the job and a camera that lets you see what we see, before and after.

Why North Portland Homeowners Choose Bellows Air Duct & Vent Co.
Our trucks have been crossing the St. Johns Bridge since 2012, and we’ve built a reputation in neighborhoods like Kenton and St. Johns by doing what we said we’d do and standing behind it. North Portland homeowners tend to stay put - they know their houses, they know when something’s off, and they don’t have patience for a hard sell or a bait-and-switch.
We answer our own phone. Twenty-four hours a day, a live person at our office picks up - not an app, not a voicemail tree. Our technicians are background-checked, uniformed, and equipped with Rotobrush and Nikro gear that matches what serious HVAC contractors specify. Every job gets a camera inspection before we start and after we finish, so you’re not taking our word for anything.
The 90-Day Done Right Promise applies to every North Portland home we enter. If something isn’t right, we return at no charge. No paperwork to file, no argument to win. That’s been our practice since 1984, and it’s not changing.
We also keep a permanent 5% Senior and Veteran discount, and we honor our $89 Seasonal Tune-Up for homeowners who want to stay ahead of problems before the rainy season hits.
Air Duct Cleaning Services We Offer in North Portland
Air Duct Cleaning
Complete cleaning of supply and return ductwork, registers, and grilles using professional-grade Rotobrush and Nikro equipment. We handle the irregular retrofit systems common to North Portland’s 1910s-1940s housing stock, navigating tight crawl spaces and mixed galvanized-to-flex transitions that standard equipment can’t manage. Learn more about our Air Duct Cleaning in North Portland.
Dryer Vent Cleaning
Lint accumulation in dryer vents is a leading cause of house fires, and older North Portland homes often have vent runs that are longer or more convoluted than modern code allows. We clear the full run from appliance to termination, test airflow, and flag any installation issues that could create a hazard. Learn more about our Dryer Vent Cleaning in North Portland.
HVAC Cleaning
Beyond ducts, we clean blower assemblies, evaporator coils, and plenums where biological growth from North Portland’s humid crawl spaces often takes hold. This service is particularly valuable for homes with heat pumps working overtime through Portland’s extended rainy season. Learn more about our HVAC Cleaning in North Portland.
Duct Repair & Sealing
Corroded seams in original galvanized trunk lines and gaps where flex duct was spliced into older systems are common in St. Johns and surrounding neighborhoods. We seal these pathways to stop unfiltered crawl-space air from entering your living areas, improving efficiency and air quality together.
Air Quality & Sanitizing
For homes with documented mold or mildew concerns - especially relevant given 97203’s damp microclimate - we apply EPA-registered sanitizers after mechanical cleaning. We don’t fog and hope; we target treated areas based on camera findings and homeowner reports.
Neighborhoods We Serve in North Portland
We keep our service radius tight so we can respond quickly and know the housing stock we’re walking into. Most North Portland calls reach us within 30-45 minutes during business hours.

- Kenton - early 20th-century foursquares with mixed-era duct additions
- University Park - dense pre-WWII housing with irregular access
- Piedmont - hillside transitions with moisture migration patterns distinct from the peninsula
- Arbor Lodge - compact lots with tight mechanical spaces
Why North Portland’s Climate & Housing Affect Air Duct Cleaning
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.
Technicians working St. Johns regularly encounter original galvanized trunk lines from 1950s-60s furnace retrofits where corroded seams splice into flex duct additions, creating unfiltered pathways that pull damp air directly from Slough-adjacent crawl spaces into living areas. This isn’t a theoretical concern. We’ve opened ducts in North Portland homes and found active mold colonies thriving on condensation that simply doesn’t form at the same rates in Bethany’s newer construction or Cedar Mill’s higher ground. Portland’s rainy season runs roughly October through May, and North Portland’s low elevation compounds ambient ground moisture throughout those months. Crawl-space humidity regularly wicks into supply ducts here, making biological growth a more urgent concern than in the drier east-side or west-hills portions of the metro.
Cleaning these systems requires more than a standard brush-and-vacuum approach. Our technicians use camera-guided inspection to map irregular runs, identify seam failures, and select attachments that can navigate the tight transitions between old galvanized and newer flex without damaging either. The goal isn’t just debris removal - it’s understanding how this specific neighborhood’s geography and building history create failure modes that don’t show up in suburban tract homes.

FAQs About Air Duct Cleaning in North Portland
Most North Portland homes fall between $350 and $550 for a complete single-system cleaning, with larger or split systems reaching $650. The irregular retrofit ductwork common in 97203’s pre-WWII housing can add time but doesn’t trigger hidden fees - we price before we start. Call (844) 685-6342 for a free estimate on your specific layout.
Yes. We’ve specialized in North Portland’s craftsman bungalows and foursquares since 2012. Our equipment includes compact Rotobrush attachments designed for restricted access, and our technicians are trained to navigate mixed galvanized-and-flex systems without damaging original materials. Camera inspection lets us plan the approach before we enter the crawl space.
It can be. The 97203 peninsula’s low elevation next to the Columbia Slough creates sustained humidity in crawl spaces that wicks directly into supply ducts, especially during October through May. We’ve documented more active biological growth in North Portland retrofits than in comparable east-side or west-hills homes. If you smell mustiness or see staining around registers, a camera inspection will tell us whether cleaning, sealing, or sanitizing is the right response.
Most North Portland jobs are completed in a single visit of 3-5 hours, including setup, camera inspection, cleaning, and final verification. Complex layouts with multiple access points or significant repair needs may run longer, but we don’t leave until the camera shows clean ductwork and you’ve seen the before-and-after.
For North Portland’s older housing stock, targeted repair and sealing is usually the more practical choice. Full replacement of irregular retrofit systems runs into structural constraints and historic-preservation considerations that repair avoids. We’ll show you camera footage of the specific damage and give you both options with real numbers. Our Free Second Opinion on Any Written Estimate applies if you’ve already been quoted replacement and want another view. Call (844) 685-6342 to schedule.
