Fast, Reliable Air Duct Cleaning Across Novato
Air duct cleaning in Novato typically runs $350-$650 for a full residential system, and most jobs are completed in a single visit with camera-verified results. We’re Bellows Air Duct & Vent Co. of California, and we’ve been driving up to Novato from the Los Angeles area to serve Marin County homeowners for over 42 years. You can reach us at (855) 401-6006 - a live person answers, 24 hours a day.
Novato’s not like the rest of Marin. While coastal towns like Mill Valley catch the breeze off the Pacific, Novato sits in a semi-enclosed valley at the northern end of the county, surrounded by dry grass hills that funnel wildfire smoke and seasonal pollen straight into residential HVAC systems. That geography changes what we find when we open your ducts. We’ve cleaned systems in the Ignacio subdivisions, along Novato Boulevard, and throughout the Hamilton neighborhood - and the problems we encounter here are distinct from what we see in coastal cities. Our Air Duct Cleaning team knows the difference.
Why Bellows Air Duct & Vent Co. of California Is Novato’s Preferred Air Duct Cleaning Company
We’ve built our reputation on showing up when we say we will and leaving the job done right. In Novato, that means understanding how your home’s position in the valley affects what collects in your ducts. Our technicians are background-checked, uniformed, and trained to recognize the specific failure patterns we see in Novato’s housing stock - from delaminated duct tape in 1970s ranch homes to salt-air corrosion of sheet-metal joints in properties closer to San Pablo Bay.
Every job starts and ends with a camera inspection. You see what we see: the before condition of your ductwork, and the after. No claim without proof. Our 90-Day Done Right Promise is stamped on every invoice - if something’s not right, we return at no charge with no paperwork required. That’s been our policy since Roger Castañeda founded Bellows in 1984, and it hasn’t changed.
Calls to (855) 401-6006 are answered by a live person, not a voicemail tree. We schedule most Novato appointments within a few business days, and we’ll confirm your arrival window the morning of service. If you’re in ZIP codes 94948, 94949, or 94945, you’re in our service area.
Our Air Duct Cleaning Services in Novato
Residential Duct Cleaning
Novato’s residential stock is dominated by 1960s-1970s ranch-style tract homes, especially in the Ignacio area and along the Novato Boulevard and Rowland Boulevard corridors. Many of these systems have never been properly cleaned. We use Rotobrush and Nikro professional-grade equipment to agitate and extract debris from the full length of your duct runs, including the hard turns and junctions where particulates settle. A typical residential cleaning in Novato runs $350-$550 for a single-system home, with larger homes or dual-zone systems ranging up to $650.

Commercial Duct Cleaning
Businesses along Redwood Boulevard and in the commercial corridors near Highway 101 face the same valley-trapped smoke and pollen as residential customers, often with more intensive HVAC cycling. We clean commercial systems in offices, retail spaces, and light industrial facilities throughout Novato, working around your operating hours to minimize disruption. Commercial pricing starts around $800 and scales with system complexity - call for a specific quote.

Supply Duct Cleaning
Supply ducts deliver conditioned air to your living spaces, but in Novato they also deliver whatever your system has pulled from the valley air. After wildfire events in nearby Marin or Sonoma counties, we’ve found supply ducts loaded with fine particulates that standard 1-inch filters never caught. We clean supply runs individually when a full system service isn’t required, typically $180-$280 depending on accessibility and run length.

Return Duct Cleaning
Return ducts pull air back to your HVAC unit, and they’re often the dirtiest part of the system because they collect debris from every room. In Novato’s older homes with original sheet-metal returns, we frequently find corrosion at the joints from decades of coastal humidity exposure. Return duct cleaning runs $200-$320, with repairs to corroded joints quoted separately if needed.

Full System Cleaning
This is our most thorough service and the one we recommend for most Novato homes, especially after fire season. We clean supply ducts, return ducts, registers, grilles, and the air handler cabinet, then seal any accessible leaks with mastic. A full system cleaning in Novato typically costs $450-$650 and includes before-and-after video documentation. For homes in the Ignacio area with original 1970s flex duct, we pay particular attention to connection integrity - the cloth-backed duct tape used in that era has usually failed completely.

Video Inspection
Every Bellows job includes camera inspection, but we also offer standalone video inspection for homeowners who want to assess their system condition before committing to cleaning. This is especially valuable in Novato’s older housing stock. We’ll show you exactly what’s inside your ducts: debris buildup, mold growth, failed seals, or corrosion. A standalone video inspection is $150-$200 and is credited toward any subsequent cleaning service.

Trusted Brands We Service in Novato
We clean and service ductwork connected to all major HVAC brands, and we specify professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies for our own work - the same names serious contractors trust. For Novato customers, this means we’re not improvising with rental equipment or consumer-grade tools. The Rotobrush system we deploy for residential cleaning uses a powered brush and simultaneous vacuum extraction that dislodges debris without pushing it deeper into your system. Our Abatement Technologies HEPA filtration captures particulates down to 0.3 microns, which matters in Novato when we’re removing wildfire smoke residue. We stock common replacement parts and sealing materials locally, so most repairs are completed same-day without waiting for shipments.
Common Air Duct Cleaning Problems We See in Novato Homes
- Wildfire smoke particulate loading. Novato’s valley position traps smoke from Marin and Sonoma fire events, and standard HVAC filters miss the finest particles. These deposit deep in ductwork and recirculate for months after visible smoke clears. We remove them with agitation cleaning and HEPA extraction, not just surface vacuuming.
- Failed duct tape seals in 1970s ranch homes. In the Ignacio-area subdivisions and along Rowland Boulevard, original cloth-backed duct tape has delaminated after 50+ years. Conditioned air blows into crawlspaces, wasting energy and drawing in crawlspace debris. We replace failed tape with mastic seals that last.
- Salt-air corrosion of sheet-metal joints. Homes closer to San Pablo Bay or with outdoor air intakes exposed to coastal humidity show accelerated corrosion of duct fasteners and joints. Leaks develop within 10-15 years, reducing system efficiency and allowing unfiltered air into your ducts.
- Thermal swing degradation of flex duct. Novato’s daily pattern - cool, humid marine air overnight, then afternoon heat baking to 85°F or higher - stresses flex duct materials. The liner separates from the wire coil, and connections loosen. This is especially common in Hamilton neighborhood homes with retrofitted or mixed ductwork systems.

FAQs - Air Duct Cleaning in Novato
Novato’s inland valley position traps wildfire smoke from nearby Marin and Sonoma fires, loading ducts with fine particulates that standard 1-inch HVAC filters cannot capture. We recommend a full system cleaning after each significant fire season, with HEPA-filtered agitation to remove particles that have settled deep in your duct runs. Call (855) 401-6006 to schedule a post-fire-season inspection - estimates are free.
Hamilton homes were built on the redeveloped Hamilton Air Force Base with a mix of mid-century original structures and early post-conversion retrofits, often using incompatible ductwork materials and connection methods. The daily thermal swing between cool marine air and afternoon heat accelerates seal degradation, especially where flex duct meets rigid trunk lines. We inspect these transition points with our camera system and reseal with mastic, not tape. Call for an inspection if you’re noticing uneven airflow or higher energy bills.
Yes - video inspection is especially valuable for Ignacio-area homes with original 1970s ductwork, because we regularly find delaminated cloth-backed duct tape and disconnected flex duct that homeowners cannot see from the registers. The $150-$200 inspection cost is credited toward any cleaning or repair work we perform, and it gives you a documented record of your system’s actual condition. Call (855) 401-6006 to book a standalone inspection.
Most Novato homes benefit from professional duct cleaning every 3-5 years, but homes in heavy wildfire smoke exposure zones or with original 1960s-1970s ductwork should consider every 2-3 years. The combination of valley-trapped particulates, thermal swing stress on materials, and aging housing stock means Novato systems accumulate debris faster than coastal Marin homes. We offer a free assessment to recommend an interval based on your specific home and system age.
Yes - our camera inspection includes visual assessment of sheet-metal joints, fasteners, and accessible trunk lines for salt-air corrosion, which we see more frequently in Novato homes closer to San Pablo Bay. If we find corrosion-related leaks, we’ll show you the footage and quote repair options before proceeding. Our 90-Day Done Right Promise covers all repair work. Call (855) 401-6006 to schedule.
