Why Bellows Air Duct & Vent Co. Is Rockville’s Preferred Air Duct Cleaning Company
We’ve been serving Connecticut homeowners since 2012, and Rockville’s mill-era housing stock is some of the most challenging ductwork we encounter anywhere in the state. Our Air Duct Cleaning team knows the difference between a purpose-built system and the field-fabricated transitions common in worker cottages off Ward Street or the converted tenements near the old Hockanum woolen mills.
Our customers in Rockville call us back because we show them the problem before we fix it. Every job starts and ends with a camera inspection. There’s no claim without proof. Our 90-Day Done Right Promise is stamped on every invoice - if it’s not right, we return at no charge, no paperwork, no arguing. That’s been our way for over 14 years.
Calls are answered by a live person, 24 hours a day. Not a voicemail, not an app. When your basement’s humid and you smell something coming from the vents, you want to talk to someone who can send a technician, not press buttons.
Our technicians are background-checked and uniformed, every time. They know Rockville’s streets, they know the parking situation around the older mill blocks, and they know how to get equipment into basements that were dug in 1890 and never intended for modern HVAC service.
Our Air Duct Cleaning Services in Rockville
Residential Duct Cleaning
Rockville’s dominant housing - triple-deckers, worker cottages, and converted tenements built between 1880 and 1930 - was never designed for forced air. Ducts got added decades later, snaked through closets, doubled back through wall cavities, and sometimes dead-ended where a later renovation blocked the original path. We clean these systems differently. Our technicians scope first, map the actual airflow, and then select brush heads and vacuum attachments that fit irregular trunk lines without damaging aging transitions. A typical residential duct cleaning in Rockville runs $350-$550 for a single-family worker cottage or first-floor unit, and $450-$650 for a full triple-decker.
Commercial Duct Cleaning
Former mill buildings along the Hockanum have been converted to offices, light industrial, and residential lofts. These spaces often retain oversized industrial-era duct remnants or entirely ad hoc HVAC installations. We clean commercial systems in Rockville with the same upfront pricing and camera verification, but with equipment scaled to larger trunk lines and the flexibility to work around business hours. Commercial duct cleaning in Rockville typically starts at $800 and ranges to $2,500 depending on system size and accessibility.
Supply Duct Cleaning
Supply ducts push conditioned air into your rooms. In Rockville’s retrofitted systems, supply runs are where we most often find blockages - wool fibers from the old mills, decades of dust accumulation in dead-end sections, or collapsed flex duct where someone squeezed a line through a too-small wall cavity. We scope every supply branch before cleaning to identify these problems. Supply duct cleaning as a standalone service in Rockville runs $200-$400.
Return Duct Cleaning
Return ducts pull air back to the furnace. In Rockville’s older homes, returns are often panned joist cavities or sheet-metal chases shared with plumbing lines - configurations that collect debris and moisture differently than standard ductboard. Our return duct cleaning includes inspection for mold in uninsulated basement runs, a particular concern given Rockville’s valley humidity. Standalone return duct cleaning in Rockville is typically $180-$350.
Video Inspection
This is where our Rockville work starts. We feed a camera through your system before any cleaning begins, and again when we’re done. You see what we see: the dead-end behind the closet wall, the shared chase with the kitchen drain, the section where a previous owner crushed the duct with a renovation. Video inspection is included with every full system cleaning, or available separately for $150-$250.
Full System Cleaning
For Rockville homeowners who want the complete job: supply ducts, return ducts, trunk lines, registers, grilles, and the air handler cabinet. We scope, clean, verify, and treat with antimicrobial where valley moisture has promoted mold growth. Full system cleaning in Rockville ranges from $550-$950 for typical mill-era homes, with larger converted commercial spaces quoted individually.

Trusted Brands We Service in Rockville
We clean ductwork connected to every major HVAC brand, and we carry professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies - the same names serious contractors specify when they’re building systems from scratch. For Rockville customers, this means we can source replacement parts and specialized attachments quickly, without waiting on cross-country shipping. Our Rotobrush systems handle the tight radius bends common in retrofit ductwork, while our Nikro HEPA vacuums contain debris rather than redistributing it through your house. When we encounter a system with Honeywell or Aprilaire air cleaners integrated into the ductwork, we know how to remove, clean, and reinstall those components without disturbing their calibration.
Common Air Duct Cleaning Problems We See in Rockville Homes
- Dead-end duct runs hidden behind closet walls. Standard vacuum-and-brush rigs push past these branches without cleaning them, leaving decades of debris untouched. We scope first, then use flexible whips and compressed-air tools to reach where brushes can’t.
- Field-fabricated duct transitions crumbling from age and humidity. Rockville’s valley moisture accelerates corrosion in uninsulated basement runs. We identify weak transitions during our video inspection and flag them for repair before cleaning begins, avoiding damage that would create new air leaks.
- Mold and mildew in dirt crawl spaces and uninsulated basements. The Hockanum River valley traps humidity higher than surrounding upland areas. We apply antimicrobial treatment in affected sections, not as an upsell, but as standard practice where our inspection shows colonization.
- Shared chases with plumbing lines collecting condensation. In triple-deckers, ducts and drains sometimes occupy the same wall cavity. This creates unique contamination patterns that require targeted cleaning and, occasionally, coordination with a plumber to access the full run.

FAQs - Air Duct Cleaning in Rockville
Your triple-decker was built between 1880 and 1930 for mill workers, before forced-air heating existed. Ducts were added decades later by different owners, often piecemeal, with runs snaked through existing wall cavities and closets. A later renovation - a bathroom added, a wall moved - sometimes blocked the original path, leaving a dead-end section that still connects to your trunk line. We find these with our video scope before cleaning, then clear them with specialized tools standard brush rigs can’t reach. Call (844) 685-6342 for a free inspection.
Rockville sits in the Hockanum River valley, where humidity runs higher than in surrounding upland towns like Tolland or South Windsor. This moisture accumulates in uninsulated basement ducts and dirt crawl spaces, accelerating mold and mildew colonization. We account for this by inspecting for biological growth during our pre-cleaning video scope and applying antimicrobial treatment where indicated, not as an add-on but as necessary work. Without this step, mold recolonizes within weeks. Call (844) 685-6342 to schedule.
Yes. We selected our Rotobrush and Nikro equipment specifically for tight-access jobs like Rockville’s mill-era basements. Our HEPA vacuums roll through standard doorways, and our brush cables navigate radius bends tighter than most residential systems require. On Maple Street, we cleaned a 1920s triple-decker where the second-floor supply run dead-ended behind a closet wall, filled with decades of wool fibers from the Hockanum mills. Using our Rotobrush system with a Nikro HEPA vac, we scoped the line, cleared the blockage, and restored airflow - something a standard brush rig would have missed. Call (844) 685-6342 to arrange a free estimate.
Yes. We’ve cleaned ductwork in converted mill buildings along the Hockanum with oversized industrial-era remnants and entirely ad hoc HVAC installations. These jobs require scaled equipment, flexible scheduling around business hours, and technicians who understand how to work with systems that have no standard documentation. Commercial duct cleaning in Rockville starts at $800. Call (844) 685-6342 for a site-specific quote.
Supply ducts push heated or cooled air to your rooms; return ducts pull air back to the furnace. In Rockville’s retrofitted systems, supply runs are more prone to blockages from debris accumulation in dead-end sections, while returns are more likely to show mold from valley moisture in uninsulated basement runs. The cleaning approach differs: supplies need targeted debris removal in irregular branches, while returns often require antimicrobial treatment in moisture-affected sections. We scope both separately and clean according to what we find. Full system cleaning covers both. Call (844) 685-6342 for pricing.
