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, MA typically runs $350 – $650 for a full residential system and is scheduled within a few days, not weeks. Call (361) 326-5060 for a written estimate before any work starts.
We know Lowell’s housing. Our crews work the triple-deckers in the Acre, the converted mill lofts downtown, and the Greek Revival cottages scattered through Belvidere. Dispatch and scheduling run through our Boston office, but the trucks that roll to Lowell carry Rotobrush agitation tools and Nikro negative-air machines sized for the tight access, shared flues, and century-old debris this city’s buildings throw at us. Parking’s restricted on most of these narrow streets. We plan for it. We don’t cut corners on hose length or HEPA filtration because the curb’s tight.
Lowell isn’t a generic market to us. The ductwork here carries lint from textile-mill days, coal dust from pre-conversion heating, and mouse-nested debris in galvanized returns that newer cities simply don’t have. That history changes how we scope the job, what we find, and what we document before we leave.
Why Hollis Air Duct Cleaning Is Lowell’s Preferred Air Duct Cleaning Company
We’ve been in business since 2004 as part of the Garrison Partners family. The Garrison Standard means written prices, written guarantees, and a 365-Day Done Right Promise on every job. In Lowell, that standard matters because the work is more complex than a suburban ranch with straight runs and modern flex duct.
Our technicians are background-checked and uniformed. You know who’s walking into your building before they arrive. Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops. No callback queues on a Monday morning.
The price is written down before any work starts, and it does not move at the door. We’ve heard from Lowell homeowners who got a $99 coupon quote that ballooned to $800 once the van was in the driveway. That doesn’t happen here. One flat price per system, agreed in writing, with before-and-after photos of your own ducts so you see what came out.
We coordinate with Lowell’s inspectional services when our camera inspections find cross-connected flues or illegal taps between units. That’s not a delay. That’s doing the job by the book, protecting the owner from liability, and making sure the cleaning actually reaches the ductwork that serves your unit alone.
Air Duct Repair in Lowell
Air Duct Repair in Lowell often starts with a camera inspection that reveals something worse than dust: separated seams in original sheet-metal ductwork, rust-through from decades of condensation, or illegal cross-taps between triple-decker units that have to be uncoupled before any cleaning can happen safely.
We repair what we can scope. That means sealing separated joints with duct mastic rated for the pressure your system runs, replacing rusted sections with galvanized metal that matches the original gauge, and documenting code violations for the property owner when we find them. In mill conversions and triple-deckers, we regularly encounter ducts that were retrofitted in the 1970s or 1980s with materials that have degraded past the point of cleaning.
When Repair Beats Replacement
A single separated seam in a straight supply run can be sealed and tested for less than the cost of full replacement. We mark the repair location, photograph the before condition, and guarantee the seal for 365 days. If it fails, we come back at no charge.
Code Violation Documentation
When our camera finds a furnace flue illegally tapped into a neighbor’s supply, we stop work, record the footage, and provide a written summary for Lowell’s inspectional services. We don’t proceed until the cross-connection is resolved. Cleaning a shared flue without addressing the tap would leave debris in place and create a liability the owner doesn’t need.
Ductwork Cleaning in Lowell
Ductwork Cleaning in Lowell means source removal from systems that have been accumulating debris since the Grover Cleveland administration. The rotary brush systems and negative-air machines we use are standard commercial-grade equipment, but the application here is specific to this city’s housing stock: agitating century-old lint and coal dust without damaging fragile galvanized returns, and maintaining negative pressure so nothing escapes into occupied spaces during the job.
We clean supply ducts, return ducts, and the trunk lines that connect them. In a typical Lowell triple-decker, that can mean accessing ductwork through multiple points because the original design didn’t include the service ports modern systems have. We cut access panels where needed, seal them properly after, and document every opening.
Full System vs. Partial Cleaning
A full system cleaning covers every supply and return run from the air handler to the register. Partial cleaning, sometimes requested by landlords for turnover units, focuses on the runs serving a single apartment. We price both in writing before we start. The full system runs $350 – $650 in Lowell. Partial runs for a single unit in a triple-decker typically fall between $200 – $400 depending on access.
Dryer Vent Stack Cleaning
Triple-deckers share dryer vent stacks through the entire height of the building. Cleaning only the visible portion from the laundry room leaves lint packed in the upper runs. That’s the leading fire factor in these buildings. We run the full stack from roof cap to appliance connection, or from the basement cleanout if the roof access is restricted.
Trusted Brands We Service in Lowell
Our equipment roster includes Rotobrush rotary brush systems for agitation, Nikro negative-air machines for source containment, and filtration products from Honeywell and Aprilaire that we install when a cleaning reveals the existing filter media is inadequate for the debris load. We stock common replacement parts for these brands so Lowell customers aren’t waiting on a warehouse shipment when a repair is needed. For commercial jobs in the converted mill buildings, we bring Abatement Technologies HEPA filtration scaled to the larger air handlers those spaces run. Every tool is explained in plain terms before we start, so you know what the machine does and why we’re using it on your particular system.
Common Air Duct Cleaning Problems We See in Lowell Homes
- Cross-connected flues in triple-deckers. In the Acre and Lower Highlands, we regularly find furnace flues illegally tapped between units during our pre-cleaning camera inspection. Cleaning one apartment’s ducts while ignoring a shared flue leaves debris in place and can redistribute contaminants between units.
- Restricted equipment access in mill conversions. Original sheet-metal ducts in these buildings often have no loading zone and street parking limited to two-hour zones. Crews who don’t plan for this arrive without adequate hose length or negative-air capacity and skip sections of the system.
- Shared dryer vent stacks with packed lint. Triple-decker laundry rooms connect to a single vertical stack. Lint accumulates through the full run, not just at the trap. Cleaning the visible four feet and calling it done leaves the fire hazard intact two floors up.
- Seasonal moisture damage. Cold, snowy New England winters and humid summers mean Lowell ductwork runs hard year-round. Condensation in uninsulated attic and basement ducts breeds mold, while ice dams and spring melt push water into the system, accelerating rust and debris adhesion.
Pricing for Air Duct Cleaning in Lowell, MA
A typical full residential duct cleaning in Lowell runs $350 – $650 for a complete system with 8 – 15 supply and return registers. Partial cleaning for a single unit in a multi-family building falls between $200 – $400. Dryer vent stack cleaning for a triple-decker runs $150 – $300 depending on height and access. Commercial duct cleaning in converted mill buildings starts around $800 and scales with square footage and HVAC complexity.
What moves the price: number of registers, access difficulty (crawl spaces, sealed basements, no parking), contamination level (heavy lint and debris take more time), and whether we find code violations that require inspectional services coordination before work can proceed. We don’t quote per-vent. One flat price per system, written down before we touch anything. Call (361) 326-5060 for an exact quote. Estimates are free.

FAQs About Air Duct Cleaning in Lowell
Yes, but we camera-inspect first to map which runs serve which unit legally. If we find an illegal cross-tap, we document it and coordinate with Lowell’s inspectional services before proceeding. We don’t clean shared flues that violate code. Call (361) 326-5060 to schedule an inspection.
We plan for restricted parking, no loading zones, and original sheet-metal ducts without modern access ports. Our crews carry extra hose length and portable negative-air units that don’t require curb access for large trailer-mounted equipment. We cut and seal access panels where needed, and we scope the full system before agitation begins. For a written estimate on your mill building, call (361) 326-5060.
The shared vent stack is likely packed with lint above your unit. Cleaning the trap and the first few feet of duct doesn’t reach the accumulation two floors up. We run the full stack from roof cap to appliance connection, or from basement cleanout when roof access is restricted. A properly cleared stack dries a load in one cycle and removes the leading fire factor in these buildings. Call (361) 326-5060 to schedule.
We remove lint from textile-mill occupancy, coal dust from pre-conversion heating systems, mouse-nested debris in galvanized returns, and modern contaminants like pollen and dander that have adhered to the old debris layer. The rotary brush agitates material that has been compacted for decades; the negative-air machine captures it before it enters your living space. We show you before-and-after photos of your own ducts. Call (361) 326-5060 for an estimate.
Yes. Year-round hard running means more air volume passing through the same debris. Seasonal condensation in uninsulated attic and basement ducts creates mold-friendly conditions, while ice dams and spring melt introduce water that rusts metal and cements debris to duct walls. We inspect for moisture damage during every cleaning and document findings for the owner. Call (361) 326-5060 to schedule before the next heating season.
