Fast, Reliable Air Duct Cleaning Across Randolph
Air duct cleaning in Randolph typically runs $350-$650 for a standard single-family home, with most jobs completed in one visit and camera-verified results before we leave. We serve Randolph from our route along Route 28 and North Main Street, usually arriving same-day or next-day for calls placed before noon.
We’ve been driving these roads since 2012 - past the old industrial parcels near Crawford Square, through the neighborhoods off North Street and Pleasant Street, up toward the Braintree line. Randolph homeowners know their houses: the raised-ranches with the original furnaces still ticking, the split-levels on quiet streets where the basement smells faintly of mildew every October. We know them too. That’s why our Air Duct Cleaning team doesn’t quote blind over the phone. We look first, with a camera, then we tell you what you’ve actually got.

Why Bellows Air Duct & Vent Co. Is Randolph’s Preferred Air Duct Cleaning Company
Forty-two years in this trade means we’ve cleaned ducts in houses that were new construction and watched them turn into vintage homes needing a second look. Randolph’s 1960s and early 1970s housing stock - ranch, raised-ranch, split-level - represents some of the most challenging ductwork we encounter on the South Shore. Original galvanized sheet metal, uninsulated, running through damp crawl spaces or beneath slabs. We’ve developed specific protocols for these layouts because we’ve seen what happens when they’re treated like standard modern flex-duct systems.
Our reputation here is built on not needing to be called back. The 90-Day Done Right Promise is stamped on every job: if it’s not right, we return at no charge, no paperwork, no arguing. That’s backed by our K.E.Y.S. values code, the same standard Ray Castillo established when he founded this company in 1984.
Calls are answered by a live person, not voicemail, not an app. Our technicians are background-checked, uniformed, and equipped with Rotobrush and Nikro systems - the same professional-grade equipment serious HVAC contractors specify. Most Randolph jobs finish in a single visit. And every one starts and ends with a camera inspection, so you see what we see.
We don’t bait with a low coupon and upsell at the door. One honest price, shown before we lift a single tool. The number on the phone is the number on the invoice.
Our Air Duct Cleaning Services in Randolph
Residential Duct Cleaning
Randolph’s single-family homes - particularly the ranches and split-levels built during the suburban boom - present a specific challenge. Original ductwork in these houses was designed for heating-only systems, often with bare metal trunks running through unconditioned basement plenums or crawl spaces. Our residential cleaning protocol begins with a video inspection to map the system, identify access points, and locate any structural degradation before we start agitation and extraction. We cleaned a 1964 raised-ranch on North Street where the original galvanized supply trunk had rusted through at a joint above the crawl space. Our techs used a Rotobrush system with an antimicrobial fogger, cutting two access panels to reach a 50-year accumulation of construction debris and rodent nesting - a job out-of-town flat-rate crews had previously skipped.
Commercial Duct Cleaning
Randolph’s commercial base includes small professional offices along Route 28, retail spaces in the Crawford Square area, and light industrial facilities near the Canton line. These buildings often share the same era of construction as the residential stock, with rooftop units and original metal ductwork that has never been properly maintained. Our commercial protocol accommodates business hours, minimizes disruption, and delivers camera-documented results for property managers and facility directors who need records for insurance or lease compliance.
Supply Duct Cleaning
Supply lines in Randolph’s older homes deserve particular attention. Original duct joints in slab-on-grade homes separate from freeze-thaw movement, creating hidden gaps that leak conditioned air into crawl spaces and pull mold into living areas. We inspect supply trunks with remote cameras before cleaning, then seal accessible joints with mastic where appropriate. The supply system is what delivers air to your bedrooms and living spaces - if it’s compromised, every room downstream suffers.
Return Duct Cleaning
Return ducts are the lungs of the system, and in Randolph’s woodland-edge location near Blue Hills Reservation, they work overtime. Elevated seasonal pollen and mold-spore loads infiltrate HVAC intakes at rates measurably higher than in more urbanized neighbors like Braintree or Quincy. Return duct cleaning removes the accumulated debris that restricts airflow and forces your furnace to run longer and harder through Randolph’s extended heating season, October through April.
Full System Cleaning
For homes with original ductwork that’s never been serviced - a common scenario in Randolph’s 02368 zip code - we recommend full system cleaning that encompasses supply trunks, return plenums, branch lines, and the air handler cabinet. This is not a quick vacuum job. It requires multiple access cuts, mechanical agitation with Rotobrush or Nikro equipment, HEPA extraction, and antimicrobial treatment where microbial growth is present. Most full system jobs in Randolph run $550-$850 and are completed in one day.
Video Inspection
Every job we perform in Randolph starts and ends with video inspection. For homes with crawl space ductwork or slab-embedded supplies, this is non-negotiable. We need to see rust, separation, debris loading, and microbial growth before we quote, and we need to document clean surfaces after we finish. The camera doesn’t lie, and we don’t ask you to trust us without proof.

Trusted Brands We Service in Randolph
We clean and service ductwork connected to all major HVAC brands, and we stock components from Honeywell and Aprilaire for common repairs and upgrades encountered in Randolph’s older systems. Honeywell media air cleaners and Aprilaire humidifier pads are frequent add-ons in homes where the original furnace has been upgraded but the ductwork remains vintage. Having these parts on our trucks means we don’t delay your job ordering components. Our Nikro and Rotobrush cleaning equipment is specified for the tight-radius bends and rectangular metal trunks common in mid-century construction. When we find a failing duct section that needs repair or sealing, we carry the materials to do it same-day rather than rescheduling.
Common Air Duct Cleaning Problems We See in Randolph Homes
- Original duct joints separating in slab-on-grade homes. Randolph’s freeze-thaw cycles move soil and concrete, stressing rigid metal connections. Gaps pull crawl space air - damp, mold-laden - directly into living spaces. Video inspection finds these separations; mechanical agitation and sealing fix them.
- Shared trunk lines in two-family buildings accumulating decades of tenant debris. Randolph’s substantial stock of 1960s-era duplexes and small multifamily buildings often has single trunk lines serving multiple units. Landlords rarely schedule cleaning between tenants, so debris layers accumulate for twenty or thirty years. These systems require coordinated access to all units and specialized HEPA containment.
- Uninsulated ducts sweating in damp crawl spaces. Randolph’s humidity band, combined with cold New England winters, produces condensation on bare metal ductwork in unvented crawl spaces. This moisture fosters microbial growth that vacuuming alone won’t address. Our protocol includes antimicrobial fogging where cameras confirm biological contamination.
- Construction debris and rodent nesting in never-cleaned systems. Fifty years of accumulation is not uncommon in Randolph’s original ranch homes. Sheet metal trunks make excellent rodent highways when access panels are missing or poorly sealed. We remove the debris, sanitize the surfaces, and seal the entry points we can reach.

FAQs - Air Duct Cleaning in Randolph
Every 3-5 years for original systems, or sooner if you notice musty odors, reduced airflow, or visible dust discharge from vents. Randolph’s extended heating season and woodland-edge pollen loads mean these systems work harder and accumulate debris faster than comparable homes in drier climates. Call (844) 685-6342 to schedule a video inspection and we’ll tell you exactly where your system stands.
Yes - video inspection is specifically designed to locate rust, joint separation, debris loading, and microbial growth in inaccessible duct runs. Split-level homes in Randolph frequently have supply trunks routed through unconditioned crawl spaces where condensation and freeze-thaw damage concentrate. Our cameras reach bends and junctions that visual inspection cannot. The video record becomes your documentation of pre-existing conditions and post-cleaning results.
Flat-rate crews optimized for modern flex-duct systems don’t carry the equipment or time allocation for mid-century metal ductwork in crawl spaces. They vacuum accessible registers and leave the buried trunk lines untouched. Randolph’s 50-year-old systems need access panel cuts, mechanical agitation in rectangular metal trunks, and antimicrobial treatment for moisture damage - procedures that don’t fit a 90-minute appointment window. We’ve been called in after discount cleanings to finish jobs that were barely started.
We use Rotobrush mechanical agitation systems and Nikro HEPA extraction equipment, supplemented with Honeywell and Aprilaire components for repairs and upgrades. Rotobrush’s flexible cable and brush assemblies navigate the tight-radius bends common in Randolph’s ranch and split-level ductwork. Nikro’s negative-air machines maintain containment during aggressive cleaning of heavily loaded systems. These are the brands HVAC contractors specify, not the consumer-grade units sold online.
Yes - shared trunk lines serving multiple units need access to all connected spaces, and we coordinate with landlords or property managers to minimize tenant disruption. These buildings, common in Randolph’s 1960s-era multifamily stock, often have single return plenums that cannot be properly cleaned from one unit alone. We schedule a single visit when possible and provide documentation for all parties. Call (844) 685-6342 to discuss your building’s layout - estimates are free.
