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 Leominster
Air duct cleaning in Leominster for a typical single-family home runs between $450 and $800 for a full system, depending on home size and the condition of the ductwork. We serve all of Leominster, from the Victorian-era neighborhoods near Monument Square to the split-levels off Central Street. Our crews arrive with professional-grade equipment from Rotobrush and Nikro and a camera for video inspection of every trunk line before and after. Call (806) 606-6902 for a written price, delivered before any work starts.
Leominster’s housing stock tells two different stories. The dense early-1900s mill-worker neighborhoods near downtown were built for steam heat. The ranch homes and split-levels that spread outward in the 1950s through 1970s were the first generation of true forced-air construction here. Both now carry ductwork that’s 40 to 70-plus years old, and both behave differently under Worcester County’s long, sealed-tight winters. Knowing which one you live in changes how we approach the cleaning.
Why CleanRun Air Duct Cleaning Is Leominster’s Preferred Air Duct Cleaning Company
CleanRun Air Duct Cleaning is independently owned and operated under the Haven Standard, established in 2013. We’ve built our reputation in Leominster on one practice: every job gets a written price before the first panel comes off, and every duct run gets a documented photo record before the crew leaves. No verbal estimates. No vague reassurances. Customers see the inside of their return and supply ducts on camera, before and after, on every visit.
Tomas Reyes leads our crews that serve Leominster, and every technician is background-checked, uniformed, and identified by name before arrival. Our Free Second Opinion on Any Written Estimate means a Leominster homeowner with a competitor’s quote in hand can put it next to our number, in writing, with no obligation. That practice has earned us strong word-of-mouth through neighborhoods like the French Hill area and the streets off Mechanic Street, where older converted homes require a more careful hand than a generic house call provides.
Dispatch and scheduling are coordinated from the brand’s Boston office; crews serve Leominster locally. All calls are answered by a live person, 24/7. When you call, you’ll speak to someone who knows that a worker cottage off Mechanic Street has a different duct profile than a 1970s ranch near Doyle Field. That local knowledge is not decoration. It changes where we look first.
Our Air Duct Cleaning Services in Leominster
Residential Duct Cleaning
Residential duct cleaning in Leominster typically runs $450 to $800 for a complete system, including supply ducts, return ducts, the plenum, and the trunk lines. Homes in the dense early-1900s neighborhoods near downtown often fall at the upper end of that range because retrofitted ductwork includes sharp, improvised bends that take longer to clean properly. Houses that sit back from unpaved roads in the more rural stretches of Leominster also accumulate fine dust faster. We provide a written price before work begins, every time, under Haven Standard Clause 1.
Commercial Duct Cleaning
Commercial duct cleaning for Leominster storefronts, office spaces, and repurposed mill buildings runs $800 to $2,200 depending on square footage and duct complexity. Several former plastics-factory buildings in Leominster have been converted to commercial use, and their ductwork often carries decades of manufacturing residue layered with ordinary dust. Our crews work around business hours and deliver the same documented photo record we provide on residential jobs. You’ll see every trunk line before and after.
Supply Duct Cleaning
Supply duct cleaning in Leominster addresses the lines that carry conditioned air from your furnace or air handler to each register. In older Leominster homes converted from steam heat, supply ducts were frequently routed through uninsulated crawl spaces or cold basement ceilings. Those sections sweat condensation in winter, and that moisture binds dust into a crust that a standard vacuum pass will not remove. We use negative-pressure extraction with rotary agitation tools to break that crust, then camera inspection to confirm the source removal.
Return Duct Cleaning
Return duct cleaning clears the lines that pull room air back to the blower. Leominster’s long, sealed winters mean return ducts recirculate the same indoor air for months at a time, concentrating dust, pet dander, and airborne debris. In homes near unpaved roads on the city’s outskirts, fine road dust gets drawn into the return side quickly. A thorough return-side cleaning takes 45 to 90 minutes depending on accessibility and the degree of buildup, and it is included in every full-system cleaning we quote.
Video Inspection
Before we clean, we look. Every CleanRun visit to a Leominster home includes video inspection of the interior of each duct run. You see what we see. If a return line in your second-floor duct has a tear or a disconnected joint, that matters more than any amount of agitation. Our written price reflects what the camera shows, not what a phone estimate guesses. After the work, we photograph the same runs again so you can compare. That documented photo record is a standard deliverable, not an upsell.

BeforeAfterTrusted Brands We Service in Leominster
Our crews work on systems from every major manufacturer, and we routinely service Aprilaire filtration components and Honeywell media cabinets installed across Leominster. For commercial jobs and heavy soil conditions, we run Abatement Technologies HEPA-filtered negative air machines to contain debris during cleaning. We use Guardsman and Rotobrush agitation equipment sized for both tight residential runs in older mill-worker homes and longer commercial trunk lines in converted factory buildings. Because we serve Leominster regularly, our trucks carry replacement filters and common access-panel hardware rather than ordering from a warehouse after the fact.
Common Air Duct Cleaning Problems We See in Leominster Homes
- Condensation-fed mold in uninsulated basement runs. Homes in the neighborhoods near the former factory corridors south and west of downtown frequently have supply ducts routed through cold, uninsulated crawl spaces. Winter condensation soaks the interior, and mold grows deep in joints where a register wipe never reaches.
- Debris traps at sharp improvised bends. Steam-heat conversions in early-1900s worker cottages and two-families forced ductwork into spaces never designed for it. Those sharp bends catch dust, pet hair, and construction debris, restricting airflow and forcing blower motors to overwork.
- Accelerated dust loading from unpaved roads. Homes on Leominster’s unpaved rural roads and long gravel driveways pull in fine dust that deposits quickly into the return side. With windows sealed for four to five months each year, that dust recirculates continuously instead of airing out.
- Early blower motor failure from restricted airflow. Restricted ducts make the blower work harder. We see PSC blower motors in older Leominster homes overheat and fail early when they’ve been pushing against clogged or crushed duct runs for years.

FAQs - Air Duct Cleaning in Leominster
Plan for a full cleaning every 2 to 3 years if your Leominster home sits on a dirt or gravel road. The fine dust from unpaved surfaces gets drawn into the return side quickly, and with windows sealed for most of the winter, it recirculates constantly. You’ll notice the difference on your return registers before you see it in the air. If you’ve never had the system cleaned, start with a video inspection to establish a baseline. Call (806) 606-6902 for a written price and an honest look at what’s actually in your ductwork.
Duct cleaning alone will not correct uneven heating, but it often removes one layer of the problem. Steam-heat conversions in Leominster’s mill-worker neighborhoods frequently have sharp, improvised bends and poorly sealed joints that restrict airflow. Cleaning those restrictions helps, but if the underlying ductwork is undersized or leaking, the imbalance will persist. We’ll show you exactly what the camera finds and give a written price for any sealing or repair work with no obligation to proceed.
Yes. Most of the crawl-space ductwork we clean under early-1900s homes in Leominster is accessible through existing access panels or return grilles. We run fuel-powered agitation equipment and inspection cameras through the existing openings, which keeps us from cutting into finished surfaces. In the rare case where a section is inaccessible, we’ll tell you before starting and include the limitation in writing. The photo record covers every run we could physically see and reach.
If the temperature near your ducts stays below the room’s dew point, condensation will return within weeks and mold will follow. Older Leominster homes with supply ducts running through uninsulated crawl spaces or cold basement ceilings are especially prone to this. The fix is thermal: insulate or relocate the duct run, or isolate it from the cold surface. Our crews identify exactly where condensation is forming and provide a written quote for the repair, not just another cleaning. Call (806) 606-6902 to schedule an inspection.
Yes. Wood heat introduces fine ash and particulate into the indoor air, and your HVAC return ducts pull a portion of that into the system. Homes in Leominster that burn wood as a primary or supplementary heat source should expect a full cleaning every 2 years. We also recommend checking the air filter monthly during burn season and switching to a pleated filter rated MERV 8 or higher. A video inspection will tell you exactly how much wood particulate has settled in the trunk line.
