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.

AfterAir Duct Cleaning in Lowell, MA
Dryer vent cleaning in Lowell costs between $89 and $279 for most homes, while full duct cleaning runs $349 to $685 for a typical triple-decker unit. The dense mill-worker housing stock and canal-corridor moisture mean Lowell ductwork clogs faster than in newer suburbs, and the work often requires reaching duct runs that were never designed for forced air. Call (806) 606-6902 and you’ll get a written price before a single panel comes off.
Why Lowell Homes Are Different
Lowell’s ductwork is shaped by the city’s textile-mill architecture. Most of the housing stock in the Acre, Back Central, and Lower Belvidere is late-1800s triple-deckers built for radiator heat. When those buildings were converted to forced air, contractors ran ducting through closets, wall cavities, and uninsulated basement ceilings, creating sharp bends and dead zones where lint and debris settle. The result is a system that fights against its own geometry.
Then there’s the canal effect. The Pawtucket Canal corridor and the Merrimack River keep ambient humidity higher than in upland towns like Westford or Pepperell. Combine that with five-plus months of furnace use and you get condensation cycling inside basement duct runs. We regularly find sagging flex duct in shared basement utility spaces holding standing water year-round, which feeds mold and explains a lot of the musty-odor calls we get from those blocks.
Converted mill lofts along the canal district add another layer: unusually long duct runs through thick brick walls with access points that were never meant to be opened. Cleaning those systems takes different tools and more patience than a standard suburban ranch. That’s not a complaint, it’s just the job in Lowell.
Our Main Lowell Services
Two services account for most of the calls we take from Lowell homeowners. Here’s what each involves in this city’s housing stock.
Air Duct Cleaning in Lowell
Whole-system negative-pressure extraction on the supply and return side, with a camera record of every run before and after. In Lowell, that means navigating the retrofit reality: ducts threaded through closets in a Belvidere triple-decker need a different approach than an open basement in Pawtucketville. We photograph the interior of each run so you can see what was actually there. Full details are on Air Duct Cleaning in Lowell.
HVAC Cleaning in Lowell
Cleaning the blower assembly, evaporator coil, plenum, and drain pan as part of a full system service. Lowell’s older furnaces often sit in dirt-floor basements where dust and moisture load the coil faster than in newer construction. We remove what’s there, document it, and leave the coil pulling air the way it should. See HVAC Cleaning in Lowell for the full scope and pricing.

BeforeAfterDryer Vent Cleaning in Lowell
Dryer vent cleaning in Lowell runs $89 to $279 depending on run length, access, and how long it’s been since the last cleaning. The city’s triple-deckers and mill lofts make this job matter more than in most places: long multi-story vent runs, shared basement utility corridors, and five-plus months of dryer use each year mean lint builds to levels we rarely see in newer single-family homes. We’ve pulled 3-inch-thick matting out of a single elbow in an Acre basement more times than we can count. That’s what the camera shows before we touch anything, and it’s why we document every run with before-and-after photos. Our full Dryer Vent Cleaning service applies the same written-price rule to every Lowell job.
Dryer Vent Inspection
Signs you need it
Clothes take more than one full cycle to dry, the dryer feels hot to the touch, or you smell a musty odor near the laundry area in your Lowell apartment.
What it costs in Lowell
A standalone camera inspection runs $49 to $99, and that fee is waived when you book a full vent cleaning with us.
How we do it
We run a camera through the full vent path from dryer to exterior termination, photograph every bend and blockage, and show you the images before recommending any work.
Vent Cleaning
Signs you need it
The exterior vent hood has visible lint hanging from it, or you haven’t had the vent cleaned in more than one year in a Lowell triple-decker.
What it costs in Lowell
Standard vent cleaning runs $89 to $189 for a single run, with longer or multi-story runs in mill conversions landing closer to $279.
How we do it
We use a Rotobrush rotating whip paired with negative-pressure extraction to break loose and pull out lint without leaving debris behind in the run.
Lint Removal
Signs you need it
You can see lint packed behind the dryer, the vent flap doesn’t open fully when the dryer runs, or a previous cleaning clearly missed a section of the run.
What it costs in Lowell
Heavy lint removal from a severely clogged run runs $129 to $229, reflecting the extra passes needed to clear years of buildup.
How we do it
We work the whip through the full run in stages, photograph each cleared section, and finish by verifying airflow at the exterior termination with a meter reading.
Bird Guard Installation
Signs you need it
You’ve had birds, squirrels, or insects nesting in the exterior vent termination, or you hear scratching near the vent outlet on an upper floor of your Lowell home.
What it costs in Lowell
Barrier-style guards with installation run $89 to $149 per termination, with custom-fit guards for odd-sized mill-building terminations priced on site.
How we do it
We install a corrosion-resistant metal guard over the exterior termination, seal the perimeter, and verify that the dryer’s airflow still meets manufacturer spec.
What Dryer Vent Cleaning Costs in Lowell
| Item | Typical range in Lowell |
|---|---|
| Camera inspection only | $49 - $99 |
| Standard single-run vent cleaning | $89 - $189 |
| Heavy lint removal / long multi-story runs | $129 - $279 |
How often should a dryer vent be cleaned in a Lowell triple-decker?
Every 12 months, and sooner if you notice slow drying or lint at the exterior hood. Basement runs through shared utility spaces in the Acre and Back Central often need attention at shorter intervals because humidity accelerates lint compaction.
Call (806) 606-6902 and we’ll put a camera in the run first. The written quote comes after you see what’s there.
Does living near the canals in Lowell make dryer vent clogs worse?
Yes, indirectly. Higher ambient humidity along the Pawtucket Canal corridor causes lint to stick to the vent walls rather than blowing through. We see more frequent partial clogs in canal-adjacent blocks than in drier upland sections of the city.
If your vent terminates into a shared basement corridor or a brick wall, a camera inspection is the fastest way to know what you’re dealing with.
Duct Repair & Sealing in Lowell
Duct repair and sealing in Lowell typically runs $180 to $740 per project, depending on how much of the system was damaged by age, moisture, or a poor retrofit installation. The city’s older triple-deckers often have duct joints that pull apart in uninsulated basements or runs crushed flat in wall cavities, and those leaks quietly drive up heating bills through the Merrimack Valley’s long winters. When we open a duct run in Lowell, the photo record shows exactly what’s failing before we price the fix. Duct Repair & Sealing follows the same written-price rule as every other job we do.
Duct Sealing
Signs you need it
Rooms that never reach the temperature on the thermostat, or dust accumulation that returns within days of cleaning in your Lowell home.
What it costs in Lowell
Sealing accessible duct joints and seams with mastic runs $180 to $420, with full-system sealing in larger retrofits landing between $420 and $640.
How we do it
We locate leaks with a pressure test or visual inspection, seal each joint with fiberglass-mesh-reinforced mastic, and photograph the finished work before reassembly.
Flex Duct Repair
Signs you need it
Flex duct runs that sag in your basement, have been crushed by stored items, or show condensation staining on the exterior jacket.
What it costs in Lowell
Replacing a damaged flex run costs $120 to $240 per run, though sagging runs in shared basement corridors that need re-supporting land around $200 to $320.
How we do it
We replace the damaged section, support the run so water can’t pool at low points again, and verify airflow at the register before finishing.
What Duct Repair & Sealing Costs in Lowell
| Item | Typical range in Lowell |
|---|---|
| Duct joint and seam sealing (mastic) | $180 - $420 |
| Full-system sealing in larger homes | $420 - $640 |
| Flex duct replacement per run | $120 - $320 |
Why do Lowell triple-deckers have so many duct leaks?
Most were converted from radiator heat decades ago, and the ductwork was routed through cavities that were never meant to hold it. Joints flex with seasonal temperature swings and separate over time. We find the same leaking-pattern in building after building.
If you notice uneven heating between floors, a pressure test will identify the exact leak locations. The written quote covers the fixes, not a guess.
Can you repair ducts in a converted mill loft without opening the walls?
Yes, when the damaged section is accessible from the basement or utility corridor. When the run disappears into a brick chase, we use camera inspection to find the failure point, then quote access work honestly. Some mill-building repairs require opening a small section of wall, and we’ll tell you before any cutting happens.
Air Quality & Sanitizing in Lowell
Air quality and sanitizing work in Lowell runs $149 to $529 for most residential treatments, and the city’s moisture profile makes this service especially relevant. Canal-corridor humidity, basement duct runs that collect condensation, and retrofitted systems with dead zones where mold takes hold mean a meaningful share of Lowell homes carry invisible biological load in their air stream. We show the camera footage first, then write a price. Our Air Quality & Sanitizing service includes the same documented photo record as every CleanRun job.
Mold Treatment
Signs you need it
Musty odor that persists after cleaning, visible dark staining inside a duct run or on a register, or a family member with unexplained respiratory irritation in your Lowell home.
What it costs in Lowell
Surface mold treatment inside accessible duct runs and on registers runs $200 to $400, with deeper contamination in long mill-building runs reaching $529.
How we do it
We apply an EPA-registered antimicrobial treatment to affected surfaces, document the coverage with photos, and recommend moisture-source corrections so the problem stays gone.
Odor Removal
Signs you need it
Cooking, pet, or tobacco odor that returns after normal cleaning, or a stale smell that activates when the furnace blower kicks on in your Lowell unit.
What it costs in Lowell
Whole-system odor treatment typically runs $149 to $249, with stronger biological or smoke odors requiring additional passes up to $349.
How we do it
We treat the duct surfaces and plenum with a non-toxic deodorizer, then run the system to distribute it evenly before photographing the treated areas.
What Air Quality & Sanitizing Costs in Lowell
| Item | Typical range in Lowell |
|---|---|
| Whole-system odor treatment | $149 - $249 |
| Surface mold treatment, accessible runs | $200 - $400 |
| Deep contamination / long mill-building runs | $400 - $529 |
Does sanitizing the ducts fix the musty smell in my Lowell basement?
It treats what’s on the duct surfaces, but the smell will return if the moisture source isn’t addressed. Sagging flex runs and uninsulated basement ducting are the usual culprits in the Acre and canal-adjacent blocks. We’ll document both the treatment and the moisture finding.
Call (806) 606-6902 and we’ll put a camera in the run before recommending a treatment. You’ll see exactly what’s growing there.
Is the antimicrobial treatment safe for pets and kids?
We use EPA-registered products labeled for occupied residential spaces, and we ask you to vacate only for the short application window specified on the label. The written quote lists the product name so you can verify it before we start. No surprises, no mystery chemicals.
Brands We Service in Lowell
Our Lowell crews work with Abatement Technologies and Rotobrush negative-pressure systems, and we keep Guardsman antimicrobial products on the truck for same-visit sanitizing. If your system needs a replacement part, most common items are stocked locally or arrive within two business days. See our brands for the full roster.

What pushes the price up in Lowell is access and run length. Mill-loft conversions with duct runs buried in brick walls cost more than a standard basement job in Pawtucketville because they take longer to reach, not because the work is different. Whatever the number, you get it in writing before any work starts, under Haven Standard Clause 1.

FAQs About Air Duct Cleaning in Lowell
We schedule most Lowell jobs within a few business days, and we group calls by neighborhood when possible. Since crews are assigned from the Boston office but work locally, same-week scheduling is common. We never promise a same-day slot we can’t reliably hit, and we’ll tell you the actual window when you call (806) 606-6902.
If you own a unit in a converted mill building, check your condo documents: some associations require advance notice for work in shared utility corridors. For a standard triple-decker you own, no permit is needed for cleaning or sealing. When a repair requires touching shared building systems, we’ll flag it before we start.
Yes, and this is one of the most common jobs in Lowell’s older multi-unit buildings. We coordinate with the owner or property manager when the duct run passes through a shared space, and we document the condition of the run before and after so there’s a record of exactly what was in there.
