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.
Fast, Reliable Air Duct Cleaning Across Lowell
Air duct cleaning in Lowell costs $425-$780 for a typical triple-decker apartment or single-family home, and $950-$1,400 for converted mill lofts with long, hard-to-access duct runs. We schedule Lowell jobs within 3 to 5 business days and complete most residential systems in a single morning. If you’re dealing with musty air, dust that returns days after you clean, or ducts that haven’t been touched since your building was converted from radiators to forced air, call (806) 606-6902 for a written quote before any work begins.
Lowell’s housing stock is unlike anything in surrounding towns. Triple-deckers built between 1880 and 1920, mill lofts converted in the 1980s and 1990s, and dense blocks in the Acre and Back Central where buildings share walls and basement utility spaces all present unique ductwork challenges. We know these buildings because we’ve cleaned hundreds of them. When a duct run disappears into a masonry chase behind a closet wall in a Pawtucketville three-family, we don’t guess. We run a camera, show you what’s inside, and clean what we can actually reach.
Why CleanRun Air Duct Cleaning Is Lowell’s Preferred Air Duct Cleaning Company
We don’t ask Lowell homeowners to take our word for anything. Every job includes a documented photo record of the inside of every duct run, before and after. You see the debris we removed, the mold we addressed, and the clean metal or flex duct we leave behind. That record is yours to keep, and it’s backed by our 365-Day Done Right Promise, written into every work order under the Haven Standard our company has operated under since Tomas Reyes founded it in 2013.
Lowell customers call us because word spreads in triple-decker neighborhoods when a crew actually shows up, actually photographs the work, and actually stands behind it. We’ve served more than 52,000 homes since 2013, and every one of them got a written price before a single panel came off. In a city where half the housing stock was never designed for forced air, that kind of accountability matters. We answer the phone with a live person, we background-check every technician, and we name our people before they arrive.
Our Air Duct Cleaning Services in Lowell

We don’t treat Lowell like a generic suburb. The buildings here are different, and our Air Duct Cleaning team approaches them differently. Here’s what we do for Lowell homes and apartments.
Residential Duct Cleaning
Triple-deckers and single-family homes in Lowell typically have 8 to 14 duct runs, depending on how many radiators were ripped out during conversion. We clean every supply and return run with negative-pressure extraction using Rotobrush and Nikro equipment, not a shop vac. In the Acre, Back Central, and the Highlands, we regularly find flex duct routed through shared basement spaces with low spots that hold standing water. We identify those sags with camera inspection and clean what’s actually there.

Commercial Duct Cleaning
Converted mill buildings along the Pawtucket Canal and the Hamilton Canal corridor house offices, studios, and mixed-use commercial space on floors 2 through 6. Those buildings have duct runs that stretch 40 to 80 feet through brick chase walls with no access panels. We use Abatement Technologies negative-air machines sized for commercial volumes and video inspection to map every run before we clean. If we can’t reach a section, we tell you before we start, not after.

Supply Duct Cleaning
Supply ducts in Lowell homes carry the air you breathe, and they’re often the dirtiest part of the system. In triple-deckers retrofitted with flex duct, supplies frequently slope incorrectly and collect condensation. In canal-district lofts, uninsulated metal supplies sweat against brick in summer. We clean from the plenum to the register, and we photograph every segment. You see what was there and what it looks like when we’re done.

Return Duct Cleaning
Return ducts in older Lowell buildings pull air from hallways and living spaces through wall cavities that were never sealed. That means dust, pet hair, and sometimes rodent droppings from basement chases end up in your return side. We clean returns separately from supplies, because they fail separately. If your building shares a return stack with other units, we coordinate with the owner or condo association before we start.

AfterTrusted Brands We Service in Lowell
We clean and service systems built around whatever equipment is already in your building, whether it’s a modern forced-air furnace in a Belvidere single-family or a retrofit handler in a Boott Mills loft. Our crews work daily with Honeywell thermostats and filtration, Aprilaire media cabinets, and ductwork that was often installed decades after the building went up. If your system uses equipment from any major manufacturer, we’re familiar with it. If a component needs replacement, we’ll show you the manufacturer part number in writing before we order it.
Common Air Duct Cleaning Problems We See in Lowell Homes

- Flex duct sagging in shared basements. In triple-deckers across the Acre and Back Central, landlords ran flex duct through basement utility spaces without proper support. We find low points holding standing water and mold in nearly every building of this type we service.
- Uninsulated metal duct sweating inside masonry chases. Canal-district lofts and converted mill buildings have ducts routed through thick brick walls. During humid Merrimack Valley summers, that metal sweats, rusts, and grows mold that spreads to registers and the air handler.
- Debris buildup behind blocked access points. Long duct runs inside brick walls often have no access panels. We use video inspection to locate blockages and negative-pressure equipment to pull debris back to a reachable point, rather than cutting holes blindly.
- Shared dryer vent stacks in multi-unit buildings. Dense Lowell housing often routes dryer vents from multiple floors into a single stack. Lint accumulates at joints and elbows, and when one unit’s dryer backs up, everyone smells it. We clean shared stacks with written coordination from the property owner.

We Also Serve Cities Near Lowell

Our crews work throughout the Merrimack Valley, including Dracut, Chelmsford, Tewksbury, and Billerica. If you’re in a suburban single-family in Chelmsford or Tewksbury, your ductwork was probably purpose-built and doesn’t have the retrofit issues we see in Air Duct Cleaning in Lowell proper. But the same written-pricing standard and photo documentation apply to every job we do, regardless of town.

FAQs - Air Duct Cleaning in Lowell

The filter isn’t the problem. Lowell triple-deckers built for radiators were retrofitted with flex duct routed through uninsulated basement spaces and wall cavities. When Merrimack Valley humidity rises in spring, condensation forms inside those ducts, especially at low points where flex sags. That moisture grows mold that your furnace filter can’t catch because the mold is downstream of the filter. We find this in nearly every pre-1920 triple-decker we service. Call (806) 606-6902 and we’ll show you exactly where the moisture is with camera inspection.
Yes, with written authorization from the property owner or condo association. Shared stacks in mill conversions are long, often 30 to 60 feet, with multiple bends inside brick walls. We clean them with powered rotary brushes and negative-pressure collection, and we photograph every section we reach. If a section is inaccessible, we’ll document that and tell you before work begins. Call (806) 606-6902 and we’ll coordinate with your association directly.
We use video inspection first. A small camera goes into the duct through an existing register or a small access point, and we map the entire run before cleaning. If we need to create an access opening, we cut a clean, sealed panel in a discrete location, usually a closet or basement bulkhead. We show you exactly where we’ll make the opening and get your approval in writing first. After cleaning, we seal the joints to NADCA standards and leave the access panel accessible for future service.
We schedule by floor and unit, working from a written scope that lists every unit, the number of runs in each, and the price for the entire building. One contact at the association approves the scope, and we coordinate access with individual owners or tenants. For buildings where duct runs are shared between units, we clean those shared sections once, document it, and include the photo record for every unit affected. Call (806) 606-6902 for a written building-wide quote.
Because the previous cleaning probably never reached the actual return runs. In converted mill lofts, return air often travels through wall cavities and chases that were never sealed or cleaned. The registers look clean because they’re just the endpoints. If the dust is coming back days later, the debris is still in the cavity between the register and the return plenum. Our video inspection shows you what’s actually in that cavity, and our negative-pressure equipment removes it. Call (806) 606-6902 and we’ll show you the difference on camera.
What Lowell Residents Should Know About Retrofit Ductwork
Lowell’s 19th-century triple-deckers and converted mill buildings often route forced-air ductwork through uninsulated masonry chases and shared basement utility corridors. These retrofit paths trap moisture and debris at rates unseen in purpose-built suburban homes of Chelmsford or Tewksbury. A 1990s colonial in Chelmsford has ductwork designed for the building. A triple-decker off Merrimack Street has ductwork that was crammed into whatever space existed when someone decided radiators weren’t enough. The difference matters, and it changes how we clean.
In a triple-decker off Merrimack Street in the Acre, our crew found a flex duct run that a previous retrofit had sagged into a low spot in the shared basement, holding standing water and coating the supply and return ducts with mold. We cut out the offending section, sealed the joints to NADCA standards, and ran camera inspection to confirm full source removal before restoring airflow to all three floors. That’s what real duct cleaning in Lowell looks like. It’s not a $79 coupon and a shop vac. It’s knowing where the ductwork fails in this city and fixing it.
The Merrimack River and the historic canal network keep ambient humidity elevated in Lowell from April through September. Combined with five-plus months of furnace use every winter, that humidity creates condensation cycling inside uninsulated duct segments, especially basement runs in canal-adjacent blocks. This is why musty smells return every spring in the Acre, Back Central, and the canal district, and why a generic cleaning that doesn’t address the moisture source won’t solve the problem.
If you live in a Lowell triple-decker, a converted mill loft, or any home where the ductwork was retrofitted rather than designed, call (806) 606-6902. We’ll give you a written price, a documented photo record of your actual ducts, and a cleaning that addresses the way ductwork actually fails in this city.
