Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterFast, Reliable Air Duct Cleaning Across Woburn
Air duct cleaning in Woburn typically runs $350 – $650 for a single residential system, with most jobs scheduled within a week and completed in one day. We’re the Woburn crew homeowners call when they want the price written down before the truck rolls, not after the technician is inside.
Our dispatch team answers live out of the Boston office, and our technicians know Woburn’s roads well enough to hit the window: the I-93 corridor up from the south, Route 128 cutting east-west, the tight streets around downtown’s mill blocks, and the winding hills above Horn Pond. We’ve cleaned ducts in 19th-century triple-deckers near Montvale Avenue, in sprawling 1960s ranches off Lexington Street, and in the office parks clustered along the I-95 belt. That range matters because a downtown tenement with original sheet-metal ductwork needs a different machine and a different approach than a newer build with flex runs. We bring both.
Every job starts with a written price that does not move. Every job ends with before-and-after photos you can actually see. And every job carries our 365-Day Done Right Promise in writing: if the work fails within a year, we come back and make it right at no charge, including a free second visit. Call (361) 326-5060 for a free estimate.
Why Hollis Air Duct Cleaning Is Woburn’s Preferred Air Duct Cleaning Company
We’ve been in business since 2004 as part of the Garrison Partners family, and that track record predates most of the duct cleaning outfits currently advertising in Middlesex County. Our Air Duct Cleaning team doesn’t compete on the lowest teaser price; we compete on discipline. Show up inside the window. Price it in writing before touching anything. Do it by the book. Leave the site clean. That’s The Garrison Standard, and it’s how we operate in Woburn.
Our technicians are background-checked and uniformed. You know who’s walking into your home before they arrive. Phones are answered by a live person 24 hours a day, seven days a week. No voicemail loops, no callback queues, no waiting until Monday for a scheduling question.
The 365-Day Done Right Promise covers every repair in writing for a full year. If it fails, Hollis returns at no charge. That’s not a satisfaction guarantee; that’s a specific commitment with a specific remedy. Woburn homeowners who’ve been burned by crews that vanished after the invoice was paid understand the difference.
HVAC Duct Cleaning in Woburn
HVAC Duct Cleaning in Woburn means pulling debris from the entire forced-air system: supply ducts that push conditioned air to your rooms, return ducts that pull it back, and the trunk lines that connect them to your air handler. For Duct Sealing - Woburn homes with aging connections, this cleaning often reveals where joints have loosened over time. In Woburn’s housing stock, this job varies enormously. A downtown triple-decker on Main Street may have 1920s sheet-metal ducts with hand-crimped joints that leak at every seam. A 1960s ranch in Four Corners might have three separate systems with long flex runs that sag and trap debris in low spots. A newer apartment near the I-95 corridor could have tight, well-sealed ductwork that cleans quickly but sits in the path of constant highway particulate. We price each system separately, in writing, before we start.
A typical single-system HVAC duct cleaning in Woburn runs $350 – $550. Two-system homes, common in the larger ranches and splits near Horn Pond, range $550 – $850. Three-system properties, which we see regularly in the Four Corners area’s expanded 1960s builds, run $750 – $1,100. Commercial systems in Woburn’s office parks along Route 128 start around $800 and scale with square footage and access difficulty.
Negative-Air Method with HEPA Filtration
We connect a Nikro negative-air machine to your duct system, creating suction that pulls loosened debris toward a sealed collection point while a HEPA filter traps particles as small as 0.3 microns. This matters in Woburn because stirring up highway particulate or old heating-oil residue without proper containment just redistributes it through your house. The negative-air method achieves source removal, not surface disturbance.
Rotary Brush Agitation for Sheet-Metal Ducts
Older Woburn homes with original sheet-metal ductwork need mechanical agitation to dislodge baked-on debris. Our Rotobrush rotary brush system spins a flexible cable through the duct, scrubbing the interior walls while the negative-air machine pulls the loosened material away. Without agitation, a vacuum-only pass on old metal ducts just cleans the easy spots and leaves the rest.
Vent Cleaning in Woburn
Vent Cleaning in Woburn targets the supply and return registers you can see, plus the short branch lines behind them that feed into your main trunk. This isn’t a full system cleaning, but it’s the right scope when your primary problem is visible dust at the registers, reduced airflow from a clogged branch, or a specific room that never heats or cools evenly. In Woburn, we see this call most often from homeowners in newer apartments near the highway corridors, where register filters clog fast with particulate, and from owners of 1950s-60s ranches where flex duct sags have created debris traps just behind the wall.
A typical vent cleaning job in Woburn, covering 10 – 15 registers and the accessible branch lines, runs $200 – $350. If inspection reveals that the debris extends deeper into the trunk lines, we’ll show you the camera footage and quote the full system scope in writing before proceeding. No surprises.
Register and Grille Deep Cleaning
We remove each register and grille, clean them outside your home with compressed air and agitation tools, then reinstall them. In Woburn’s older homes, we often find registers painted shut by previous owners; we free them without damage and note any that need replacement. The difference in airflow is immediate and measurable.
Branch Line Camera Inspection
Before we call a vent cleaning complete, we run a camera through the branch lines to confirm the debris didn’t extend past the accessible section. In Woburn’s 1960s ranches with sagging flex duct, this step catches debris traps that a surface cleaning would miss entirely. You see the footage. We explain what it means. Then you decide.
Trusted Brands We Service in Woburn
Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation, Nikro negative-air machines for controlled debris extraction, and filtration products from Honeywell, Aprilaire, and Guardsman. We don’t use hardware-store vacuums with a long hose attached. The tools we bring are the same ones commercial crews use in hospitals and schools, maintained on schedule and sized correctly for residential ductwork. For Woburn homeowners, this means we can handle both the delicate flex duct in newer builds and the stubborn, baked-on residue in century-old sheet metal without damaging either. Parts and replacement filters for Honeywell and Aprilaire systems are stocked for fast turnaround when a cleaning reveals a component that needs swapping.
Common Air Duct Cleaning Problems We See in Woburn Homes
- Black, sooty return ducts near the I-93/I-95 interchange. In the Four Corners area and other neighborhoods bordering the highway triangle, we routinely find returns coated with a dark film that homeowners mistake for mold. It’s actually a mix of tire and brake dust from constant traffic and old heating-oil residue from decades of combustion heating. Camera inspection confirms the difference before anyone spends money on mold remediation they don’t need.
- Leaking original sheet-metal ductwork in downtown tenements and triple-deckers. The hand-crimped joints in pre-war Woburn housing leak at every seam. A crew without proper negative-air containment and agitation tools just stirs dust into the living space instead of removing it. We seal accessible joints with duct mastic after cleaning, improving both air quality and system efficiency.
- Sagging flex duct with debris traps in 1950s-60s ranches. The flexible ductwork common in Woburn’s mid-century housing sags between supports over time, creating low spots where debris accumulates out of sight. A surface vacuum pass never reaches these pockets. Our camera inspection finds them; our rotary brush and negative-air combination cleans them.
- Multiple systems quoted as one, then rushed or skipped. A two- or three-system home in the Four Corners or Horn Pond areas gets quoted a single flat price by some competitors, who then clean one system thoroughly and barely touch the others. We price each system separately in writing, so you know exactly what you’re paying for and can verify each was completed.
Pricing for Air Duct Cleaning in Woburn, MA
Here’s what air duct cleaning costs in Woburn’s market, based on the system count and scope we see most often:
| Service Scope | Typical Range in Woburn |
|---|---|
| Vent cleaning (10 – 15 registers, branch lines) | $200 – $350 |

| Commercial system cleaning (per system) | $800 – $1,500 |
| Video inspection add-on | $75 – $125 |
What moves the price: system count (each air handler is a separate job), duct material and condition (sheet metal with heavy buildup takes longer than clean flex duct), accessibility (crawlspace runs or attic trunks add time), and whether we find conditions that need addressing before cleaning, like disconnected ducts or failed seals. We put the full scope and price in writing before any work starts. One flat price per system. No per-vent add-ons, no equipment fees that appear at the door. Call (361) 326-5060 for a free estimate.

FAQs About Air Duct Cleaning in Woburn
Yes, each system is priced separately because each is a complete, independent job with its own air handler, duct network, and debris load. In Woburn’s larger 1960s ranches and splits, especially in the Four Corners and Horn Pond areas, three-system homes are common. We quote each system in writing so you can verify each was cleaned, not just the easiest one. Call (361) 326-5060 for an exact quote – estimates are free.
Probably not. In neighborhoods near the I-93/I-95 interchange, we regularly find black, sooty buildup in return ducts that’s a mix of highway particulate and old heating-oil residue, not microbial growth. We run camera inspection to confirm before you spend money on mold remediation. A homeowner near Four Corners called about a “moldy” smell and dark coating on the returns in a three-system 1960s ranch; our tech found the black film was soot from the highway corridor plus oil residue, cleaned each system separately under negative pressure with HEPA filtration, and saved the homeowner from unnecessary mold work.
Downtown Woburn’s mill-era housing has original sheet-metal ducts with hand-crimped joints that leak and hold baked-on debris; these need rotary brush agitation and careful negative-air containment. Newer apartments near the I-95 corridor typically have flex duct that’s easier to clean but sits in the path of constant highway particulate. The equipment and time required differ significantly, which is why we inspect before quoting and put the specific approach in writing.
You get before-and-after photos from the camera inspection, a written invoice that lists each system cleaned and the scope completed, and our 365-Day Done Right Promise in writing. If we cleaned three systems, the invoice says so explicitly. If we found and addressed a disconnected duct or sealed a leaking joint, that’s noted too. The documentation is your proof of what was done, since the work itself is hidden. Demand this from any crew you hire.
Spring and fall are busiest because Woburn’s cold, snowy winters mean heating systems run nonstop for months, pulling dust and debris through ducts, while spring pollen and humid summers can foster mold in poorly maintained systems. That said, highway particulate accumulates year-round near the I-93/I-95 corridors, and we’ve done effective cleanings in every season. The right time is when you notice reduced airflow, uneven heating, or visible debris at registers. Call (361) 326-5060 to schedule.
