Fast, Reliable Air Duct Cleaning Across Montclair
Air duct cleaning in Montclair typically runs $350-$650 for a full residential system, with most jobs completed in a single visit and camera-verified before we leave. If your home was built during the 1960s through 1980s tract expansion, your attic-run ducts are likely 40-60 years old and cycling far more particulate than you realize.

Our Air Duct Cleaning Services in Montclair
Residential Duct Cleaning
Montclair’s single-story California ranch homes dominate neighborhoods from north of the 10 Freeway down toward the Ontario border. These houses were built with attic-run duct systems that have now seen four to six decades of use. Original fiberglass duct board delaminates. Early flex duct sags and tears. We clean what can be cleaned and tell you straight when replacement is the honest recommendation. A typical residential duct cleaning in Montclair runs $350-$550 for a single-system home, with whole-house packages up to $650 for larger properties near Scripps Avenue or south toward Mission Boulevard.
Commercial Duct Cleaning
Montclair’s commercial corridor along Holt Boulevard and the Montclair Place retail zone sees heavy HVAC load from May through October. We clean ductwork for retail spaces, medical offices, and small industrial tenants. Commercial pricing starts around $800 for compact systems and scales with square footage and access complexity. We work after hours to avoid disrupting your business.
Supply Duct Cleaning
Supply ducts push conditioned air into your living spaces. In Montclair, these lines often run through attics that hit 140°F in summer, degrading connections and pulling in unfiltered air through gaps. We seal accessible joints during cleaning and note where retrofits would improve efficiency. Supply-only cleaning runs $200-$350 when bundled with return service.
Return Duct Cleaning
Return ducts are where we find the heaviest contamination in Montclair homes. The return-air plenum acts like a vacuum inlet, and in neighborhoods closest to the 60/10 freeway interchange, we routinely pull out a distinctly gray-black layer of diesel ultra-fine particles. This isn’t ordinary household dust. It’s bonded to duct surfaces and often requires anti-microbial treatment after mechanical cleaning. Return duct service adds $150-$250 to a full system clean.
Full System Cleaning
Our most thorough service for Montclair homeowners. We clean supply and return trunks, branch lines, registers, and the air handler cabinet. We recently cleaned a 1970s single-story ranch on Central Avenue with original fiberglass duct board that had sagged and accumulated black diesel particulate. Our Rotobrush system extracted over 18 pounds of debris, and we recommended a full duct retrofitting to modern flex duct. Full system cleaning in Montclair runs $450-$650, with video inspection included.
Video Inspection
Every Bellows job includes camera inspection before and after. You see what we see. No claims without proof. In Montclair, video inspection often reveals delaminating fiberglass, rodent intrusion in attic systems, or the characteristic gray-black diesel soot that tells you exactly why your filters clog faster than your cousin’s in Pasadena. We document everything. The video is yours to keep.

Trusted Brands We Service in Montclair
We run professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies - the same brands serious HVAC contractors specify when they’re doing their own work. For Montclair homes with older systems, we stock adapters and fittings that fit legacy duct dimensions no longer standard in the trade. This matters when your 1978 ranch has odd-sized collars or discontinued register boots. We don’t order parts and make you wait. We carry what Montclair’s housing stock typically needs.
Common Air Duct Cleaning Problems We See in Montclair Homes
- Fiberglass duct board from the 1960s-80s delaminates indoors. The resin binder breaks down after 40+ years of heat cycling. Once the fiberglass surface is exposed, cleaning dislodges fibers into your air stream. We camera-inspect every Montclair job and recommend full replacement when delamination is present - no exceptions.
- Santa Ana winds drive desert dust into attic ducts through unsealed joints. Montclair’s location at the eastern end of the LA Basin puts it directly in the path of these dry, high-velocity wind events. Dust infiltrates through gaps in attic plenums and register boots, overwhelming standard cleaning if the source isn’t sealed.
- Diesel particulates from nearby freeways bond to duct surfaces. Montclair borders the Ontario-Chino logistics corridor, one of the densest concentrations of diesel truck freight activity in the US. Ultra-fine particles penetrate home envelopes and settle preferentially in return-air systems. Standard brushing won’t remove bonded soot; we apply anti-microbial treatment after mechanical cleaning when testing indicates diesel contamination.
- Original flex duct has sagged, torn, or collapsed in attic runs. The early flex duct used in Montclair tract homes lacked the structural wire helix of modern product. Gravity and heat distortion create low spots where debris accumulates and airflow chokes. Video inspection finds these failures without tearing open your ceiling.

FAQs - Air Duct Cleaning in Montclair
It’s likely diesel ultra-fine particulate from the Ontario-Chino logistics corridor, which borders Montclair to the south and west. The gray-black layer we find in return plenums along the 60/10 freeway corridor is chemically distinct from ordinary household dust. Anti-microbial treatment after mechanical cleaning addresses bonded soot that brushing alone won’t remove. Call (844) 685-6342 and we’ll camera-inspect to confirm what you’re dealing with - estimates are free.
Replacement is necessary once fiberglass duct board delaminates. The resin binder in 1960s-80s product breaks down after decades of attic heat cycling, exposing raw fiberglass fibers. Cleaning delaminated board releases those fibers into your air stream. We camera-inspect every job and will show you exactly what your duct board looks like before recommending either path. Call (844) 685-6342 for a video inspection - estimates are free.
Every 2-3 years for most Montclair homes, versus the 3-5 year standard for coastal Southern California. The combination of Santa Ana wind dust, heavy summer AC use, and diesel particulate infiltration accelerates contamination. Homes within a mile of the 60/10 interchange or with original 40+ year ductwork should consider annual inspection. Call (844) 685-6342 to schedule - our $89 Seasonal Tune-Up includes a basic duct assessment.
Yes. Diesel ultra-fine particles create a characteristic gray-black film on duct surfaces that is immediately visible on camera, especially in return-air plenums. We document this for every Montclair customer and can distinguish diesel soot from mold, ordinary dust, or fiberglass degradation. The before-and-after video is yours to keep. Call (844) 685-6342 to book a camera inspection - estimates are free.
Significantly. These dry, high-velocity winds push desert dust and allergens from the high desert directly into the Pomona Valley, and infiltration through unsealed attic joints adds measurable debris to duct systems. Montclair’s position at the eastern end of the LA Basin catches this accumulation more severely than cities further west. Sealing accessible duct joints during cleaning reduces but doesn’t eliminate this effect. Call (844) 685-6342 to assess your system’s sealing - estimates are free.
