Fast, Reliable Air Duct Cleaning Across Cambridge
Air duct cleaning in Cambridge, MA typically runs $350-$650 for a standard residential system and $800-$1,400 for full-service cleaning of retrofitted triple-decker or row-house ductwork. Most Cambridge appointments are completed in a single visit, with our Cambridge team usually on-site within 24 to 48 hours of your call.
We’ve been sending trucks to Cambridge since 1984, and we know the difference between a purpose-built suburban ranch and the tight, retrofitted systems that heat most of this city’s housing stock. From the triple-deckers packed along Mass. Ave near Central Square to the brick row houses backing up to the Charles River in Riverside, Cambridge presents access challenges that standard duct cleaning outfits simply aren’t equipped to handle. Narrow alley-load entries, finished basements with original plaster ceilings, and ductwork snaked through century-old chimney chases - these are the conditions we plan for before we leave the shop. Call (844) 685-6342 to speak with a live person about your building, and we’ll tell you exactly what access we’ll need and what it will cost before we schedule.
Why Bellows Air Duct & Vent Co. Is Cambridge’s Preferred Air Duct Cleaning Company
Ray Castillo has led Bellows for decades, and our reputation in Cambridge is built on showing up when we say we will and leaving systems we can prove are clean. We’ve earned strong reviews from Cambridge homeowners and property managers who’ve watched our camera inspections reveal what standard cleanings missed - debris packed into hidden duct runs, mold colonies in uninsulated basement joists, access panels buried behind drywall that no prior technician had bothered to find.
Our response time to Cambridge averages same-day or next-day for standard appointments, with emergency calls answered by a live person 24 hours a day. We don’t use an app or voicemail tree. When you call (844) 685-6342, you reach someone who can dispatch a crew, check availability, and give you an upfront price based on your specific building type - whether that’s a single-family near Fresh Pond, a rental unit in Inman Square, or a commercial space in Kendall Square.
What separates us in Cambridge is that we arrive expecting retrofitted systems. We carry flexible-shaft Rotobrush equipment and high-reach access tools because we know that Cambridge’s pre-1940 housing stock - triple-deckers, Victorians, attached row houses - was never designed for forced-air ductwork. The contractors who added it decades later routed through whatever spaces were available. We find those spaces. We clean them. And we prove it with before-and-after video.
Our Air Duct Cleaning Services in Cambridge
Residential Duct Cleaning
Cambridge’s residential market is dominated by rental units in buildings constructed between 1890 and 1945, nearly all originally heated by steam radiators with no duct infrastructure whatsoever. When forced-air systems were retrofitted, contractors ran supply and return lines through attic kneewalls, repurposed chimney chases, and exposed basement joist bays. Our residential duct cleaning accounts for these irregular geometries. We use flexible-shaft equipment from Rotobrush and Nikro to navigate tight-radius bends that rigid vacuum hoses cannot follow, and we cut access openings where needed - always with homeowner approval and always sealed properly afterward. A typical Cambridge residential job runs $350-$650 for a standard system, $800-$1,200 for complex retrofitted runs in a triple-decker or row house.
Commercial Duct Cleaning
Cambridge’s commercial base spans biotech labs in Kendall Square, retail along Harvard Square’s pedestrian corridors, and office conversions in former industrial buildings near Lechmere. Each presents distinct scheduling and access constraints. We clean commercial duct systems during off-hours or in phased segments to avoid disrupting operations, and we coordinate with building management for loading dock access and parking permits - a real concern in Cambridge’s permit-restricted zones. Commercial pricing starts at $600 for small retail or office systems and ranges upward based on square footage and system complexity.
Supply Duct Cleaning
Supply ducts deliver heated or conditioned air to your rooms, and in Cambridge’s retrofitted systems they are often the most circuitous runs - pushed through old steam-pipe risers, snaked across basement ceilings, or routed through kneewall spaces with minimal insulation. These conditions trap debris and create condensation points where mold takes hold. Our supply duct cleaning includes full video inspection to map the actual run (not just the straight sections), mechanical agitation with flexible brushes, and negative-air vacuum extraction. We then verify flow improvement with post-cleaning video. Supply-only cleaning in Cambridge typically falls between $250-$450.
Return Duct Cleaning
Return ducts pull air back to your furnace or air handler, and in Cambridge’s older buildings they are frequently the dirtiest component - large, slow-moving air streams that collect dust over decades, often in unlined joist bays or primitive sheet-metal boxes that predate modern sealing standards. Returns are also where we most commonly find evidence of pest intrusion and moisture damage. Our return duct cleaning includes sealing recommendations where we find leakage, and we always inspect the return plenum and filter rack for proper sizing - mismatched returns are common in Cambridge retrofits and directly affect system efficiency. Return-only cleaning runs $200-$400; combined supply and return service starts at $450.
For a complete assessment of your system, our Air Duct Cleaning team offers full-system cleaning with video documentation from end to end.

Trusted Brands We Service in Cambridge
We specify professional-grade equipment from Nikro, Honeywell, and Abatement Technologies - the same brands that serious HVAC contractors and industrial hygienists rely on. Our Nikro portable HEPA vacuums and Honeywell media air cleaners are stocked for Cambridge customers who need replacement components or upgraded filtration after a cleaning. Because we carry common parts and maintain direct supplier relationships, turnaround on filter upgrades and UV air purifier add-ons is typically 24 to 48 hours, not the two-week special-order delays common with discount operators. When we recommend a product, it’s because we’ve installed it in Cambridge conditions and we know it holds up to the humidity cycles and particulate load this city’s buildings generate.
Common Air Duct Cleaning Problems We See in Cambridge Homes
- Contractors clean through inadequate access points. Standard 8-inch round access holes work fine in modern ductwork, but they miss the circuitous runs through chimney chases and kneewalls that characterize Cambridge retrofits. We cut proper access where needed and carry flexible equipment that can navigate bends rigid hoses cannot follow.
- Video inspection is skipped, leaving half the system untouched. Hidden access panels behind drywall or inside closets go undiscovered by technicians who don’t inspect before they start. We camera-inspect every system before cleaning begins, and we show you what we find. No guesswork, no missed runs.
- Biocide sprays applied without addressing moisture sources. Cambridge’s location in the humid Charles River basin means freeze-thaw cycles drive repeated condensation in poorly insulated basements and crawlspaces. Spraying mold without fixing the condensation problem guarantees recolonization within weeks. We identify moisture sources and recommend insulation or dehumidification solutions alongside cleaning.
- Academic-year rental churn leaves systems uncleaned for decades. In Cambridge’s extreme rental market, a triple-decker near Central Square or Inman Square might cycle through three tenant generations without a single duct cleaning. The debris load in these systems is often 5 to 10 times what we find in owner-occupied homes, and the health implications for tenants with allergies or asthma are significant.

FAQs - Air Duct Cleaning in Cambridge
We locate hidden access panels using pre-cleaning video inspection, then cut and patch drywall or closet linings as needed with homeowner or property manager approval. Our technicians carry patching materials and paint-matched repair supplies to restore surfaces to original condition - the opening is the only way to clean the full run, and we don’t leave a mess behind. Call (844) 685-6342 and we’ll walk through your building’s likely access points before we schedule.
Extreme rental churn driven by Harvard and MIT’s academic calendar means many Cambridge triple-deckers cycle through tenants every one to two years with no duct cleaning between occupants. Layered on top is the retrofitted nature of the ductwork itself - non-standard, circuitous runs through chimney chases and kneewalls that trap debris far more readily than purpose-built systems. The combination of neglected maintenance and inherently poor duct geometry produces contamination levels we rarely see in owner-occupied suburban homes. We recommend cleaning between every major tenant turnover, or every three years minimum.
Yes, we provide video camera inspection before every job, and we can perform a standalone assessment with written documentation for $125-$195 if you need documentation for a property sale, tenant dispute, or insurance claim. The inspection shows you the actual condition of your ductwork - debris load, moisture damage, mold colonization, and access challenges - and gives us the information to quote accurately without surprises. Call (844) 685-6342 to schedule.
