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 Lawrence
Air duct cleaning in Lawrence typically runs $350 – $650 for a full residential system, and most jobs are scheduled within a few business days. Our crews serve Lawrence from our Boston office, dispatching to neighborhoods from the North Common to Tower Hill and the streets off Andover. If you’re seeing dust streaks from your registers or catching that sharp, chalky smell of drywall residue, that’s not normal wear, it’s construction debris your builder should have cleared before handover. Call (361) 326-5060 for a free estimate.
We’ve worked in enough Lawrence homes to know the local housing story: the dense triple-deckers and converted mill buildings carry a century of legacy dust in galvanized steel trunks, while the newer construction off the Merrimack and in infill lots has a different problem entirely, ducts packed with fresh construction debris that the HVAC system starts circulating the day you move in. Both need cleaning, but for different reasons and with different methods. Our Air Duct Cleaning team treats each Lawrence job by what the ducts actually contain, not by a standard template.
Why Hollis Air Duct Cleaning Is Lawrence’s Preferred Air Duct Cleaning Company
Hollis has been part of the Garrison Partners family since 2004, and our reputation in Lawrence is built on showing up when we said we would, pricing in writing before we touch anything, and standing behind the work for a full year. The 365-Day Done Right Promise means if the cleaning fails or debris returns because we missed something, we come back and make it right at no charge, including a free second visit. No negotiation, no runaround.
Our technicians are background-checked and uniformed, and you’ll know who’s arriving before they knock. Phones are answered by a live person 24 hours a day, seven days a week, no voicemail loops, no callback queues until Monday morning. In Lawrence specifically, we coordinate dispatch from our Boston office and typically schedule within a few business days, with written confirmation of your arrival window.
We know the local conditions: the mill-era triple-deckers around the North Common and Tower Hill with original ductwork running through unheated exterior walls, the new construction with tight lot lines forcing ducts through unconditioned chases, and the seasonal pattern where the first cold snap triggers calls about musty odors and visible dust puffs at registers. That local knowledge changes how we approach each job.
Air Duct Inspection in Lawrence
Air Duct Inspection in Lawrence is where every job should start, especially in new construction where the problem is invisible until it’s been circulating for months. Our technician runs a camera through your supply and return lines, looking for construction debris, disconnected joints, rust from condensation, and any signs that your builder’s crew used the ductwork as a trash chute during finish work. In Lawrence’s newly built homes, we find drywall dust and joint compound grit in roughly half the inspections we perform, the builder never called for a post-construction cleaning.
An inspection costs $150 – $250 in the Lawrence market and takes about 45 minutes. You’ll see the footage yourself, and we explain what we’re looking at in plain terms, no jargon without translation. If the ducts are clean, you pay for the inspection and know you’re set. If they’re loaded with debris, we apply the inspection fee toward your cleaning.
Video Documentation
We record the full inspection and give you the footage, timestamped and labeled by register. In Lawrence, this matters for new-construction buyers who need to document builder defects before warranty periods expire, and for owners of mill-era buildings who want to track deterioration in original galvanized steel over time.
Post-Construction Focus
New Lawrence homes need a different inspection protocol than century-old housing. We check for drywall dust compaction in branch runs, filter bypass where construction debris has damaged seals, and blower motor loading that can shorten equipment life before your first service call.
Residential Air Duct Cleaning in Lawrence
Residential Air Duct Cleaning in Lawrence covers single-family homes, condos, and the two-family and three-family buildings that dominate much of the city’s housing stock. For new construction, this is source removal, not routine maintenance: we use negative-air machines and rotary brush agitation to extract construction debris that was left in the ducts at handover, then seal and test the system before we leave. A typical residential cleaning in Lawrence runs $350 – $650 depending on system size, access difficulty, and contamination level.
We were called to a new-construction two-family off Andover Street where the homeowner noticed dust streaking from the supply registers in every room. Our tech ran a camera inspection and found the branch runs loaded with drywall dust and joint compound grit; we set up negative pressure with HEPA filtration and used agitation tools to pull the construction debris out of the ducts before the homeowner’s first full winter. The system had never been cleaned after handover, and the builder’s punch list never included it.
Negative-Air Method
We connect a Nikro negative-air machine to your trunk line, creating suction that pulls loosened debris through the system and into a sealed HEPA-filtered collector. In Lawrence’s tight new-construction lots, where ducts often run through unconditioned chases, this method also helps us identify disconnected joints that winter condensation has already started to rust.
Rotary Brush Agitation
Our Rotobrush system sends a spinning brush through each branch run, dislodging compacted drywall dust and construction grit that vacuum suction alone won’t move. For Lawrence’s older galvanized steel with decades of layered debris, we adjust brush stiffness to avoid damaging thin metal walls while still achieving full source removal.
Trusted Brands We Service in Lawrence
Hollis carries professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, the same tools commercial crews use in hospitals and schools, not hardware-store attachments. For filtration upgrades after cleaning, we stock Aprilaire and Guardsman products sized to Lawrence’s typical residential systems. We don’t guess at compatibility; we measure your trunk and branch dimensions on site and match components to your actual airflow requirements. Most replacement parts and filtration upgrades are available without a second trip, so your system is protected before we leave.
Common Air Duct Cleaning Problems We See in Lawrence Homes
- Builder-grade debris in new construction: Lawrence’s newly built homes often arrive with drywall dust, joint compound grit, and wood shavings packed into branch runs. The HVAC system distributes this debris through every room until source removal extracts it.
- Winter condensation in unconditioned chases: New-construction ductwork in Lawrence’s tight lots runs through exterior walls and unheated basements. Cold snaps cause condensation that rusts galvanized steel and loosens construction dust into the airstream.
- Misdiagnosed filter problems: Homeowners in Lawrence’s new developments replace MERV filters repeatedly, thinking the dust puffs at registers mean a filtration issue. The real problem is debris in the ductwork upstream of the filter.
- Legacy buildup in mill-era housing: In the triple-deckers and converted mill buildings around Tower Hill and the North Common, original galvanized steel trunks contain a century of textile dust, coal soot, and renovation debris that routine maintenance never addresses.
Pricing for Air Duct Cleaning in Lawrence, MA
Most full residential cleanings in Lawrence fall between $350 and $650. Air duct inspection runs $150 – $250, applied to your cleaning if you proceed. Dryer vent cleaning, often bundled with duct cleaning in Lawrence’s multi-family buildings, adds $120 – $200. What moves you within these ranges: system size (a three-decker with multiple units costs more than a single-family), access difficulty (crawl spaces versus full basements), and contamination severity (light dust versus compacted construction debris requiring extended agitation time).
We give you one flat price per system, agreed in writing before any work starts. No per-vent pricing, no add-ons at the door, no bait-and-switch. You’ll see before-and-after photos of your own ducts, not stock images. Call (361) 326-5060 for an exact quote, estimates are free.

FAQs About Air Duct Cleaning in Lawrence
Because builders in Lawrence rarely include post-construction duct cleaning in their punch lists, and your HVAC system has been pulling drywall dust, joint compound grit, and wood shavings through the blower motor since the day you turned it on. That debris doesn’t stay in the ducts, it circulates through your living space and loads your equipment. Call (361) 326-5060 for a camera inspection to see what’s actually in there.
Before your first heating season, ideally within the first 60 days. In Lawrence, the first cold snap triggers condensation in unconditioned chases that loosens construction debris and rusts fresh galvanized steel. Cleaning first, then sealing, protects your system before that damage starts. We can usually schedule within a few business days of your call.
Source removal means dislodging debris from duct walls and extracting it completely, not just sucking out loose surface dust. A quick vacuum leaves compacted drywall grit that continues to break loose and circulate. We use rotary brush agitation plus negative-air HEPA extraction to pull debris out of the system entirely, then verify with post-cleaning camera footage.
No. A high-MERV filter protects your equipment from debris that reaches the return, but it doesn’t clean debris already packed in your supply branches, and excessive filter loading can actually reduce airflow and strain your blower motor. The debris needs to come out of the ducts, not just be caught after it’s already circulating. Source removal is the fix; filtration is the follow-up protection.
Your builder should have sealed ducts during construction to prevent debris entry, cleaned all branch runs and trunks after drywall and finish work, and verified cleanliness with a post-construction inspection. Most Lawrence builders don’t, and it’s not typically covered under standard warranty language. We document what we find with video, which you can use in warranty discussions if needed.
