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.

Why Kestrel Air Duct Cleaning Is Hudson’s Preferred Air Duct Cleaning Company
We’ve been working under the Kingswell Guarantee since 2004, and that standard travels with us into every Hudson home we enter. Our technicians are background-checked, uniformed, and trained on the specific failure patterns of Hudson’s housing stock - the 1950s-1970s ranch and cape homes with galvanized-steel ductwork that dominates neighborhoods from Brigham Street to the Feltonville area.
Hudson homeowners call us back because we answer the phone with a live person, 24/7, and because our written price arrives before a single vent is touched. The Kingswell Way governs every visit: say the price, show up in the window we gave, leave the place cleaner, put the guarantee in writing, come back if it fails. Our 365-Day Done Right Promise means if the work falls short within that year, we return and make it right at no charge - documented in writing on every job, not extended as a discretionary courtesy.
We coordinate dispatch from our Boston office, but the crew that arrives at your Hudson door knows the difference between a slab-adjacent ranch crawlspace and a mill-building loft conversion. That local knowledge matters when the problem is invisible moisture in your ducts, not surface dust on your vents.
Ductwork Cleaning in Hudson
Ductwork Cleaning in Hudson addresses a specific regional problem: the Assabet River valley’s persistent ground-level humidity accelerates mold and mildew accumulation inside residential ductwork far faster than in neighboring upland communities like Berlin or Stow. The job involves source removal of accumulated debris, biological growth, and construction-era contaminants from both supply and return pathways using negative-air extraction and rotary brush agitation. A typical full-system ductwork cleaning in Hudson runs $380-$620 for a single-system ranch or cape, while homes with multiple systems or converted mill-condo layouts range $520-$720.
Supply Duct Cleaning
Supply ducts push conditioned air into your living spaces, and in Hudson’s mid-century homes they’re often the cleaner side of the system - but not always. We use Rotobrush rotary brush systems to dislodge debris at the duct wall, then pull it out with Nikro negative-pressure units so nothing resettles in your bedrooms or kitchen.
Return Duct Cleaning
Return ducts are where Hudson’s river-valley moisture does its real damage. These lines draw air back to the handler, and in ranch homes with crawlspace routing, they’re the first place we find active mold. We establish HEPA filtration before agitation begins, capturing loosened particles instead of releasing them into your living space.
Air Duct Inspection in Hudson
Air Duct Inspection in Hudson should happen before any cleaning work is priced or performed, especially in homes built between 1950 and 1978 with original galvanized-steel systems. The inspection uses video camera equipment to document the interior condition of supply trunks, return plenums, and branch lines - revealing mold colonization, debris volume, and duct integrity issues that aren’t visible from the vent cover. A standalone video inspection in Hudson costs $180-$260; it’s included at no charge when you proceed with a full cleaning. We were called to a 1968 ranch off Cox Street where the family had been running their forced-air heat continuously since November and complaints of musty air wouldn’t quit. A camera inspection of the return side revealed active mold growth inside the original galvanized-steel trunk line routed through a damp crawlspace under the slab-adjacent foundation. We set up negative pressure with HEPA filtration, used agitation tools to break the colony loose, performed full source removal on both supply and return ducts, and cleaned the air handler and blower motor - the homeowner said the difference in air smell was immediate.
Video Documentation Standards
We record the full inspection and provide timestamped footage of before and after conditions. For Hudson homeowners with multiple systems or non-standard mill-building layouts, this documentation proves which lines were cleaned and which were found intact.
Multi-System Assessment
Many Hudson ranches have a original system plus a later addition with its own handler and ductwork. We inspect and price each system separately, so you’re not paying for one flat “whole house” rate that gets cut in half when the crew realizes there’s twice the equipment.
Trusted Brands We Service in Hudson
Our crews arrive with Rotobrush rotary brush systems for dislodging debris at the duct wall, Nikro negative-pressure units for pulling contaminants out of the system, and Abatement Technologies HEPA filtration to keep loosened particles out of your living space during cleaning. For homeowners who want to maintain clean air between service visits, we carry Honeywell, Aprilaire, and Guardsman filtration and indoor-air-quality products. We stock common filtration components locally so Hudson customers aren’t waiting on shipped parts when a replacement is needed.
Common Air Duct Cleaning Problems We See in Hudson Homes
- Assabet valley mold in return plenums. The river’s humidity seeps into low crawlspaces under slab-adjacent ranch foundations, creating active mold colonies in return-air trunk lines even when the living space shows zero moisture damage. This pattern is far more common in Hudson than in higher-ground neighboring towns.
- Per-system pricing surprises. A company quotes a flat whole-house price, then discovers the home has two or three separate systems with long duct runs - the original ranch system plus an addition - and either cuts corners on the second system or tacks on surprise charges mid-job instead of pricing per-system from the start.
- Skipped return-side inspection. A technician checks the supply vents but never cameras the return plenum and main trunk lines routed through the crawlspace, missing the Assabet-valley mold colonization that is the actual reason the homeowner called in the first place.
- Inadequate containment during agitation. A crew runs brush tools and vacuum without establishing proper negative pressure or HEPA filtration, stirring mold spores and decades of galvanized-steel debris into the living space instead of capturing it at the source.
Pricing for Air Duct Cleaning in Hudson, MA
Most single-system residential ductwork cleaning jobs in Hudson fall between $380 and $620. Homes with two or more separate HVAC systems - common in ranches with additions - run $520-$720 because each system requires its own full setup, agitation cycle, and negative-pressure extraction. Video inspection alone is $180-$260, waived if you proceed with cleaning. Commercial work in converted mill buildings along the Assabet starts around $680 depending on system complexity and access.
What moves the price: the number of separate systems (we price per system, not per vent), the extent of biological remediation needed, accessibility of crawlspace trunk lines, and whether the job requires HEPA containment for active mold. We put the written price in your hands before a single vent is touched. No per-vent add-ons. No doorstep revisions. Call (469) 972-3151 for an exact quote - estimates are free.

FAQs About Air Duct Cleaning in Hudson
The Assabet River valley’s persistent humidity seeps into low crawlspaces under mid-century ranch foundations, accelerating mold growth inside return-air plenums and trunk lines that routine maintenance alone cannot address. Hudson’s housing stock - dominated by 1950s-1970s homes with original galvanized-steel ductwork rarely serviced - means our technicians routinely find active mold colonies requiring HEPA containment and source removal rather than simple debris extraction. Call (469) 972-3151 for an inspection and written quote.
We price per system, not per vent or with a single flat “whole house” rate that gets cut in half or doubled at the door. Each system requires its own Rotobrush agitation, Nikro negative-pressure extraction, and HEPA filtration setup, so a two-system Hudson home typically runs $520-$720. The written price covers every system before work begins - no surprise charges when the crew finds the addition’s handler in the attic. Call (469) 972-3151 for an exact quote.
Timestamped video inspection footage of before and after conditions inside your ducts, plus a written completion checklist documenting which lines were cleaned, which were found intact, and what equipment was used. We provide this documentation on every Hudson job because the work is invisible by design, and a homeowner should never have to trust a verbal report alone. Call (469) 972-3151 to schedule a documented cleaning.
Yes, when performed with proper agitation control and negative-pressure extraction. The risk isn’t the steel itself but decades of accumulated debris and biological growth inside it, which professional brush agitation and HEPA containment remove safely. We inspect duct integrity first and document any structural concerns before cleaning begins. Call (469) 972-3151 for a video inspection of your system.
Yes. Mill conversions often retain legacy industrial ventilation remnants and non-standard duct layouts that require custom cleaning approaches rather than residential rotary brush systems alone. We assess these buildings individually and price according to system complexity, access constraints, and whether the original ventilation infrastructure can be cleaned or needs separate handling. Call (469) 972-3151 for a specialized estimate.
