Fast, Reliable Air Duct Cleaning Across Stow
Air duct cleaning in Stow, MA typically costs between $350 and $650 for a full residential system, with most jobs completed in a single visit. We’re usually on-site in Stow within 24 hours of your call, and every job includes a camera inspection before and after so you see exactly what was in your ducts.
We’ve been driving the back roads of 01775 for decades - from the older ranches along Route 117 to the split-levels tucked behind the Stow Community Park and the farmhouses scattered near the Assabet River Reservation. Stow’s not a town you learn from a map. You learn it by crawling through damp crawlspaces beneath 1970s colonials and finding the same patterns again and again: mold in sheet-metal trunks, pollen packed into returns after oak season, and the telltale acorn shells that mean squirrels found a gap in the ductwork somewhere. Our Air Duct Cleaning team knows these houses because we’ve worked on hundreds of them. If your vents are pushing musty air or your family can’t shake spring allergies despite clean filters, call (844) 685-6342. We’ll answer live, day or night, and get you scheduled.
Why Bellows Air Duct & Vent Co. Is Stow’s Preferred Air Duct Cleaning Company
Ray Castillo built this company in 1984 on the idea that a homeowner should never have to argue about whether a job was done right. That principle runs through every house we enter in Stow. Our 90-Day Done Right Promise is stamped on every invoice - if something’s not right, we return at no charge, no paperwork, no runaround. We’ve honored it for 42 years.
Stow homeowners call us back because we show them their own ducts before we touch a tool. Our camera inspection reveals what standard cleaning companies hope you never see: the mold bloom behind the evaporator coil, the rodent debris in the return plenum, the pollen cake lining the supply trunk. After we clean, we show you again. That’s not a sales tactic. It’s the only honest way to do the work.
Our technicians are background-checked, uniformed, and equipped with Rotobrush agitation systems and Abatement Technologies HEPA containment. They report to a live person at our office 24 hours a day - not a voicemail tree, not an app. When you call (844) 685-6342, someone answers. We’ll be there when we say.
We also know Stow’s permitting environment and work within Middlesex County guidelines for any duct modification or repair. Most jobs need no permit, but when they do, we handle the paperwork so you don’t have to think about it.
Our Air Duct Cleaning Services in Stow
Residential Duct Cleaning
Stow’s housing stock demands a specific approach. The ranch-style and split-level homes built during the 1960s through 1990s dominate this market, and their original sheet-metal ductwork is now 30 to 50 years old - sized to heating loads from a different era and often running through unconditioned crawlspaces that stay damp year-round given Stow’s high water table. We clean these systems with rotary brush agitation and negative-air HEPA extraction, not just a shop vac pushed into a register. On conservation-adjacent lots near Lower Village or along the Assabet River corridor, we regularly find rodent nesting material in return-air plenums that requires sanitization beyond standard scope. Our residential cleaning includes full register and grille removal, trunk line cleaning, and a camera-verified report you keep.
Commercial Duct Cleaning
Stow’s commercial base is modest but specific - medical offices near Route 62, retail along Great Road, and light industrial near the town line. These buildings face the same woodland moisture challenges as residences, often compounded by rooftop HVAC units that draw in unfiltered pollen and spores. We clean commercial systems with minimal disruption to operations, scheduling around your hours and containing our work areas. Our equipment from Nikro and Abatement Technologies handles larger trunk diameters and longer duct runs without cutting corners on extraction power.
Supply Duct Cleaning
Supply ducts push conditioned air into your living spaces, which means any contamination there lands directly on your family. In Stow, we see supply lines clogged with fine pollen from oak, maple, and birch - far heavier loading than less-forested neighboring towns experience. We clean supply trunks, branch lines, and boots with rotary brushes and compressed-air whips, then verify flow improvement with before-and-after camera documentation. If your supply ducts run through a damp crawlspace beneath a 1970s ranch, we also inspect for mold growth on the exterior of the duct that can infiltrate through seams.
Return Duct Cleaning
Return ducts pull air back to the furnace, and in Stow they work hardest from November through March when heating systems run almost continuously. That five-month heating season recirculates dust, skin cells, and debris through returns that were never designed for modern filtration. Worse, on Stow’s larger wooded lots, returns are the entry point for wildlife. On a conservation-adjacent lot near Lower Village, we pulled a foot-long rat nest from a return-air plenum in a 1970s split-level. The lanolin and urine contamination required Abatement Technologies HEPA sanitization beyond standard cleaning. We check every return boot, plenum, and trunk for gaps that invite intrusion - and we seal what we find.
Full System Cleaning
For Stow homes with original ductwork from the 1970s or 1980s, piecemeal cleaning misses the interconnected contamination. Our full system cleaning addresses furnace cabinet, evaporator coil, blower assembly, supply and return trunks, branch lines, and registers in one coordinated visit. This is the service we recommend for first-time cleaning in older Stow homes, especially those with crawlspace duct runs or visible mold around registers. Most full system jobs in Stow run $550 to $850 and finish in four to six hours.
Video Inspection
Every Bellows job includes video inspection, but we also offer standalone inspection services for Stow homeowners who want to assess their ducts before deciding on cleaning. Our cameras navigate sheet-metal trunks and flexible duct alike, recording in HD so you see exactly what we see: rust, mold, gaps, debris, or structural damage. For homes near Stow’s wetland corridors, we pay particular attention to low points in duct runs where moisture collects and microbial growth begins. The inspection fee applies toward any subsequent cleaning.

Trusted Brands We Service in Stow
We clean and service ductwork connected to all major HVAC brands, and we carry sanitizing and sealing products from Aprilaire, Abatement Technologies, and Guardsman for Stow customers who need more than vacuuming. Our Rotobrush brush-and-vac systems agitate debris from duct walls without damaging aging sheet metal, while our Nikro and Abatement Technologies HEPA extractors maintain negative pressure to prevent contamination of your home during cleaning. For homes with Aprilaire media air cleaners or whole-house dehumidifiers - common upgrades in moisture-prone Stow basements - we inspect and service those components as part of our full system cleaning. We stock replacement filters and UV bulbs for faster turnaround, so you’re not waiting on shipped parts while your system runs dirty.
Common Air Duct Cleaning Problems We See in Stow Homes
- Mold blooms in crawlspace ductwork. Stow’s heavy tree canopy and wetland corridors along the Assabet River create persistent interior moisture in ducts, fostering mold growth more than in less-forested neighboring towns like Hudson or Marlborough. We find active mold in the supply trunks of 1960s ranches where crawlspace humidity stays above 60% year-round.
- Wildlife infiltration through aged duct joints. The original sheet-metal ductwork in Stow’s 30-to-50-year-old homes was assembled with snap-lock seams and minimal sealing. Mice, squirrels, and chipmunks from surrounding woodlands exploit these gaps, leaving nesting debris that standard vacuuming misses and contamination that requires HEPA sanitization.
- Spring pollen overwhelming filtration. Heavy oak, maple, and birch pollen from Stow’s surrounding forests spikes duct loading every April and May in ways that denser neighboring towns don’t experience. Homeowners who change filters monthly still find pollen packed into return plenums and coating supply registers.
- Retrofit ductwork with improvised connections. Some Stow farmhouses and Capes predate forced-air systems and have retrofit duct runs with connections that sag, separate, or leak conditioned air into attics and crawlspaces. We identify these problems during camera inspection and can recommend sealing or replacement options.

FAQs - Air Duct Cleaning in Stow
Homes near Stow’s wetland corridors or with crawlspace ductwork should schedule cleaning every 2 to 3 years, not the standard 3 to 5. The persistent moisture from surrounding wetlands accelerates mold growth and microbial loading in ways that drier locations don’t match. If you smell mustiness when the furnace first kicks on, or if family members have worsening allergies each spring, you’re likely due regardless of the calendar. Call (844) 685-6342 and we’ll inspect to confirm.
No - standard vacuuming removes loose debris but does not sanitize surfaces contaminated with rodent droppings, which can carry hantavirus and other pathogens. We encounter this regularly on Stow’s larger wooded lots, and we upgrade to Abatement Technologies HEPA sanitization with antimicrobial treatment when rodent evidence is present. This is a safety issue, not an upsell. We identify it during our pre-cleaning camera inspection and discuss options before proceeding.
Clean first, then decide. Many 1970s Stow systems have years of service left if properly sealed and insulated. Our camera inspection reveals whether your ducts are structurally sound or deteriorated beyond repair. Replacement typically runs $3,500 to $7,000 for a Stow ranch or split-level, while cleaning plus targeted sealing costs a fraction of that. We’ll show you what we see and recommend honestly - our 90-Day Done Right Promise applies either way, so we only suggest work that holds up.
That black dust is typically a mix of fine pollen, mold spores, and oxidized metal particles from aging ductwork, concentrated by months of continuous winter heating and then expelled when the system cycles on in spring. In Stow, the heavy oak and maple pollen load makes this pattern especially pronounced. It’s a sign your ducts are circulating contamination, not just air. A full cleaning with vent and grille removal eliminates the source, not just the symptom.
Yes, if the smell originates in your ductwork - which it often does in Stow homes with crawlspace or basement trunk lines running through damp, unconditioned space. Our camera inspection determines whether the odor source is inside your ducts or from general basement moisture. If it’s duct-related, cleaning plus sanitization removes the microbial growth causing the smell. If it’s a broader moisture problem, we can recommend dehumidification or duct sealing to prevent recurrence. Call (844) 685-6342 for a free estimate and we’ll sort out the source.
