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 Worcester
Air duct cleaning in Worcester typically runs $350 – $650 for a full residential system and $800 – $2,400 for commercial jobs, with most appointments scheduled within a week and completed in a single day. We’re Hollis Air Duct Cleaning, and our Air Duct Cleaning in Worcester crews know this city’s housing stock inside and out, from the triple-deckers stacked up Vernon Hill to the split-levels off Tatnuck Square. Dispatch and scheduling run through our Boston office, but the technicians who arrive at your door live and work in Central Massachusetts.

You know who’s walking into your home before they arrive.

We bring professional-grade equipment to Worcester jobs: Rotobrush rotary brush systems, Nikro negative-air machines, and filtration products from Honeywell and Aprilaire. These are the same tools commercial crews use, not hardware-store gear, and we explain what each one does for your system in plain terms before we start.
Vent Cleaning in Worcester
Vent Cleaning in Worcester means more than brushing out the registers you can see. In this city, it means pulling the supply and return covers in every room, agitating the full run with rotary brushes, and extracting debris under negative pressure so nothing migrates into your living space. Most Worcester vent cleaning jobs run $150 – $300 per system when done as standalone maintenance, or they’re bundled into a full duct cleaning.
Supply Vent Cleaning
Supply vents push heated or conditioned air into your rooms. In Worcester’s older homes, we often find these runs partially blocked by collapsed flexible duct or decades of compacted dust behind the register. We remove each cover, inspect with a camera when needed, and clear the full run to restore airflow.
Return Vent Cleaning
Return vents pull air back to your furnace. They’re the dirtiest points in most Worcester systems because they act as the collection grate for everything airborne in your home. We clean the grille, the boot, and the trunk connection, checking for the oily soot that basement oil furnaces deposit in these low-pressure zones.
Air Duct Repair in Worcester
Air Duct Repair in Worcester addresses the crushed, disconnected, or corroded runs we find inside walls and chases that no homeowner can see without a camera. Repair costs typically run $200 – $600 for localized fixes like reattaching a fallen flexible duct or sealing a separated seam, and $800 – $1,800 when we’re rebuilding sections of original sheet-metal trunk in a triple-decker’s vertical chase. Every repair gets a written price before work begins and is covered by our 365-Day Done Right Promise.
Crushed Run Restoration
Flexible foil ducts common in 1980s – 2000s Worcester homes tear or crush where they’re pinched against framing or sag under their own weight. We replace these with properly supported, code-compliant duct or restore rigid runs where access allows. The fix prevents the airflow restriction that forces your furnace to work harder through every January cold snap.
Triple-Decker Chase Sealing
In Worcester’s 1890 – 1920 triple-deckers, the real problem is rarely one unit’s ducts, it’s the shared vertical chase that feeds all three floors. We seal the trunk with mastic and mechanical fasteners, then test for leakage so each unit gets the air it paid to heat instead of losing it into exterior wall cavities.
Trusted Brands We Service in Worcester
We clean and repair ductwork connected to all major HVAC brands, and we stock Honeywell and Aprilaire filtration components for Worcester customers who want to upgrade while we’re already in the system. Our Nikro negative-air equipment and Rotobrush rotary systems handle the extraction side. If your furnace is a newer high-efficiency unit or an older oil-burning workhorse still common around Main South, we have the fittings and the knowledge to work with what’s there without damaging original equipment. Parts orders for less common items route through our Boston office for fast turnaround, so we’re not leaving your system open while waiting on a shipment.
Common Air Duct Cleaning Problems We See in Worcester Homes
- Shared vertical chases in triple-deckers. Cleaning one unit’s ducts without sealing and cleaning the full trunk that serves all three floors is largely wasted effort. Dust and oily soot from the other two units migrate back through the common chase within days.
- Oily soot from basement oil furnaces. Standard agitation brushes alone won’t remove the microbial film that decades of oil combustion leave inside original sheet-metal ductwork. We use negative-air source removal with HEPA filtration to extract it.
- Freeze-thaw condensation in cold attic ducts. Worcester’s harsh winters and humid summers create moisture inside uninsulated attic runs. When that moisture mixes with residual dust, it forms a sticky black paste that recontaminates the system within weeks unless ducts are dried and sanitized after cleaning.
- Crushed or disconnected flexible ducts in suburban-era homes. The 1980s – 2000s housing stock in Worcester’s west and north neighborhoods often has foil flex duct that tears during aggressive cleaning or has already collapsed from poor support, cutting airflow to entire rooms.
Pricing for Air Duct Cleaning in Worcester, MA
A typical residential air duct cleaning in Worcester runs $350 – $650 for a full system, including supply and return ducts, main trunk lines, and register cleaning. Commercial jobs start around $800 and range up to $2,400 depending on square footage and system complexity. Triple-decker buildings with shared vertical chases fall in the $550 – $950 range because of the additional sealing and chase-access work. Air duct repair runs $200 – $600 for localized fixes and $800 – $1,800 for trunk rebuilds. Vent cleaning alone is $150 – $300.
What moves the price: the number of HVAC zones, accessibility of ductwork (crawl spaces and sealed chases take longer), whether video inspection reveals damage requiring repair, and the level of contamination, oil soot being harder to remove than dry dust. We give one flat price per system, agreed in writing before any work starts. No per-vent pricing, no add-ons at the door. Call (361) 326-5060 for a free estimate.

FAQs About Air Duct Cleaning in Worcester
Because the three units share a single vertical chase ducted through uninsulated exterior walls, dust and oily soot from the other two floors migrate back into your cleaned ducts within days. We seal and clean the full trunk that serves all three floors, or we’re not doing the job right. Call (361) 326-5060 and we’ll explain what your building’s chase looks like before we quote.
It’s dust mixed with condensation from Worcester’s freeze-thaw cycles, forming a residue that standard brushing can’t fully remove and that recontaminates the system within weeks. We dry and sanitize these runs after cleaning to prevent regrowth. This problem is rare in drier New England cities but common here due to our harsh winters and humid summers.
Yes. Oil combustion leaves an oily soot and microbial film inside ductwork that rotary brush agitation alone won’t strip. We use negative-air source removal with HEPA filtration, the same method commercial crews use, to extract it without pushing contamination into your living space. Call (361) 326-5060 for an exact quote on your system.
Uneven heating between rooms, weak airflow at distant registers, or a furnace that runs constantly without reaching temperature are the common signs. We run video inspection down the full duct run to show you exactly what’s inside before we quote any repair. In Worcester’s 1980s – 2000s suburban stock, we find crushed flex duct behind walls about once in every three jobs.
Usually because the root cause wasn’t fixed: a shared triple-decker chase recontaminating the system, oily soot left behind by inadequate extraction methods, or moisture in cold attic ducts creating new paste. We identify the source during our initial inspection and address it so the cleaning lasts. Our 365-Day Done Right Promise covers the work for a full year if something fails.
