Pasadena isn’t like the rest of the LA Basin. The mountain bowl traps wildfire smoke and particulates against the range, and your ductwork pays the price. We’ve spent four decades learning what that means for the Craftsman bungalows and Spanish Colonial Revival homes that make up this city’s housing stock. Our Air Duct Cleaning crews know the difference between a 2010 tract home and a 1920s attic retrofit, and we clean accordingly.

Why Bellows Air Duct & Vent Co. Is Pasadena’s Preferred Air Duct Cleaning Company

We’ve worked in Pasadena long enough to remember when Colorado Boulevard still had the old streetcar tracks buried under asphalt. That history matters because it means we’ve cleaned ducts in the same neighborhoods - Bungalow Heaven, Madison Heights, the Linda Vista hillside - dozens of times over the years. We know which blocks have the 1910s balloon framing, which ones got their HVAC retrofits in the 1970s, and where the flex duct was run through insulation that’s been shedding fibers since the Reagan administration.

Our reputation here is built on not needing to be called back. The 90-Day Done Right Promise is stamped on every job: if the work isn’t right, we return at no charge with no paperwork required. Calls are answered by a live person 24 hours a day, not a voicemail tree. Our technicians are background-checked and uniformed, and they arrive with Rotobrush and Abatement Technologies equipment - the same brands serious HVAC contractors specify when they’re working on million-dollar installs.

Ray Castillo, who leads Bellows, set the standard in 1984 and hasn’t changed it: one honest price shown before we start, camera inspection before and after every clean, and a square deal you can count on. Pasadena homeowners who’ve been burned by bait-and-switch operators know the difference.

Our Air Duct Cleaning Services in Pasadena

Residential Duct Cleaning

Most of our Pasadena calls come from homeowners in historic districts who’ve lived in the same house for twenty or thirty years and never once thought about their ducts. That’s normal. But in a 1915 Craftsman on Mentor Avenue or a 1928 Spanish Colonial on Los Robles, the HVAC retrofit is often decades old, run through unconditioned attic space with flex connections that have been expanding and contracting through a hundred Pasadena summers. We clean the full supply and return system with HEPA-contained equipment, document everything on camera, and show you what came out. Most residential jobs in Pasadena run $350-$650 and finish in one visit.

Commercial Duct Cleaning

Pasadena’s commercial buildings span everything from Old Town retail spaces to medical offices near Huntington Hospital. Commercial systems have higher airflow volumes and different code requirements, but the same principle applies: camera inspection, contained cleaning, verified results. We work around business hours where needed, and we price upfront so there’s no disruption to your operation or your budget. Typical commercial duct cleaning in Pasadena starts at $800 and scales with system size and access difficulty.

Supply Duct Cleaning

Supply ducts push conditioned air into your living spaces. In Pasadena’s retrofitted homes, these are often the most compromised runs - flex duct routed through original 1910s attic cavities where collar connections have loosened over decades of thermal cycling. We isolate each supply branch, agitate debris with mechanical brushes, and extract it through HEPA filtration. Supply-only cleaning runs $250-$450 in most Pasadena homes, though we typically recommend full system evaluation since return-side contamination usually mirrors what we find on the supply side.

Return Duct Cleaning

Return ducts pull air back to the handler. They’re the intake side, so they collect what circulates - and in Pasadena, that includes wildfire ash particulates, ozone byproducts, and insulation fibers from compromised attic connections. The return grille filter catches some of this, but infiltration after the filter point is exactly the problem we find in post-fire inspections. Return duct cleaning in Pasadena homes typically costs $200-$400 as a standalone service, or it’s bundled into full system pricing.

Full System Cleaning

This is what we recommend for most Pasadena homeowners, especially those in historic districts with retrofit ductwork. Full system cleaning covers supply trunks, return trunks, all branch lines, and the air handler cabinet. We camera-inspect before and after, provide video documentation, and back the work with our 90-Day Done Right Promise. In Pasadena’s older housing stock, this is often the first time anyone has seen inside the ductwork since the original HVAC installation. Full system cleaning runs $500-$850 depending on system size and contamination level.

Video Inspection

Every Bellows job includes camera inspection - it’s non-negotiable. But we also offer standalone video inspection for Pasadena homeowners who want to assess their system before committing to cleaning, or who need documentation for insurance or real estate transactions. The video goes on a USB drive you keep. Standalone video inspection is $150-$250, applied toward cleaning if you proceed.

Trusted Brands We Service in Pasadena

We clean with professional-grade equipment from Rotobrush, Abatement Technologies, and Nikro - brands that HVAC contractors specify when they’re installing systems in Pasadena’s custom homes and historic renovations. We don’t show up with shop vacs and guesswork. Our HEPA-filtered negative air machines are sized for the particulate load we know exists in San Gabriel Valley ductwork, and our brush systems are selected for the delicate flex duct common in Pasadena’s retrofits. Parts and consumables are stocked locally, so if we find a damaged section that needs repair or sealing during cleaning, we can often handle it same-day without a return trip.

Common Air Duct Cleaning Problems We See in Pasadena Homes

• Flex duct joints opening in summer heat. Pasadena’s 100°F+ days cause thermal expansion and contraction in attic-run flex duct. The gaps pull ash, insulation fibers, and smog particulates directly into supply air - contamination that happens after the filter, so standard filter changes give false confidence.
• Original attic insulation shedding into collar connections. In Bungalow Heaven and similar districts, 1960s-1980s HVAC retrofits routed flex through 1910s-1920s attic cavities where old blown-in insulation still sheds fibers through poorly taped connections. The duct interior tests heavily contaminated even when the return filter looks clean.
• Post-wildfire ash infiltration. The January 2025 Eaton Fire demonstrated what Pasadena’s mountain-trapped geography means for air quality. Fine ash particles find their way into duct systems through any gap, and they don’t stay in the attic - they circulate through living spaces until physically removed.
• False security from clean-looking filters. We hear this constantly: “But I just changed my filter.” The filter is at the return grille. Infiltration through compromised attic connections happens downstream, in the supply side. The filter can’t catch what enters after it.

Pasadena’s Historic Housing Stock: What It Means for Your Ducts

Pasadena’s historic Bungalow Heaven district has nearly 1,000 Craftsman homes from 1900-1930, where original attic cavities and retrofit flex duct systems trap generations of particulate debris - a pollution load unseen in newer suburbs. These homes were built for gravity furnaces or coal stoves, not forced air. When central HVAC arrived in the 1960s through 1980s, contractors ran flex duct through balloon-framed attics never designed for it. The connections were taped, not sealed. The insulation was loose-fill, not encapsulated. And four decades of Pasadena summers - thermal cycling from 50°F winter nights to 105°F August afternoons - have opened gaps that newer construction simply doesn’t develop.

Last spring we cleaned a 1912 Craftsman on Marengo Avenue near the Bungalow Heaven boundary. The homeowner reported worsening allergies after the Eaton Fire. Our Rotobrush video inspection revealed ash and crumbled attic insulation fibers deep inside the flex duct collars - the HVAC retrofit had never been sealed to the original balloon-framed attic. We performed a full system cleaning with Abatement Technologies HEPA filtration, then documented the pre- and post-duct interior with our video inspection to show the homeowner the source of their symptoms.

This is why Pasadena homeowners need more than a standard duct cleaning checklist. They need someone who knows what a 1920s attic retrofit looks like, who expects to find insulation fibers in collar connections, and who understands that the San Gabriel Mountains don’t just make for beautiful views - they trap every ounce of wildfire smoke and ozone against the city’s northern edge, where your attic intake gaps are waiting.
