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.
Air Duct Cleaning Company in Thompsonville, CT
Air duct cleaning in Thompsonville runs $320 – $650 for a whole-home system on average, and most jobs finish in a half to a full day depending on how many returns the house has. What changes the work here is the housing stock itself: much of Thompsonville was built for mill workers a century ago, and the forced-air systems in those homes were often added decades after the walls went up. That means duct runs through tight chases, sheet-metal seams that have shifted, and years of accumulated debris no factory-fresh system would have. If you’re in a Bigelow-era cottage or a triple-decker on the east side of town, call (980) 447-2498 and we’ll tell you what we expect to find before anyone shows up.
Why Thompsonville Homes Are Different
Thompsonville grew up around the Bigelow-Sanford carpet mill, and the housing stock tells that story. Most of the homes in the village core are late-1800s to early-1900s worker cottages and triple-deckers, built with steam or hot-water radiator heat, not forced air. The duct systems we see today were retrofit later, often in the 1950s through the 1970s, and they were run through whatever space was available: narrow basement joist bays, old chimney chases, walls never designed to carry sheet metal. The result is irregular geometry, poorly sealed seams, and dead zones that standard equipment has to be worked through slowly. In the blocks nearest the old mill site, our technicians sometimes pull out matted fiber debris that looks nothing like normal household dust. That’s mill fiber from decades ago, settled into returns before the factory closed, and it’s a residue you won’t see in newer subdivisions.
The Connecticut River Valley climate adds to it. Humid summers push condensation inside ducts running through unconditioned basements, which creates a known mold and biofilm risk in Thompsonville more than in drier parts of the state. Then the heating season hits for five months straight, and the system bakes in every particle that settled during the summer. One season of neglect compounds the next, and in a house that has been heated this way for decades, the buildup is real.
Our Main Thompsonville Services
Homeowners in Thompsonville call us most often for air duct cleaning and dryer vent cleaning, with repair work close behind. Each service has its own page where you’ll find pricing, what the job covers, and the local conditions that shape the work. The short version is below, with a link to the full page for each.
Air Duct Cleaning in Thompsonville
Whole-home air duct cleaning uses negative-pressure extraction to pull accumulated dust, pet dander, mill fiber, and debris out of the return and supply runs without scattering it through the living space. In Thompsonville’s older homes, the job usually takes longer than in newer construction because the retrofit duct geometry is irregular and access points are limited. We check for separated seams and disconnected boots while we’re in there, since a leaky joint undoes half the cleaning before the system runs again. Full details, including what to expect from start to finish, are on the Air Duct Cleaning in Thompsonville page.

Dryer Vent Cleaning in Thompsonville
Dryer vents in Thompsonville’s pre-war homes are often long, narrow runs with several elbows, routed from a first-floor laundry up through a wall or out a basement rim joist. Lint catches at every bend, and in a vent shared through an old chase, the buildup is a real fire hazard. We clear the full run with a rotary brush and vacuum capture, and we check the exterior termination to make sure the flap opens freely and nothing is nesting behind it. See the Dryer Vent Cleaning in Thompsonville page for schedules and what the job covers in detail.

Air Duct Repair in Thompsonville
Older sheet metal shifts. Seams separate, boots pull away from floor registers, and return drops sag in damp basements. When that happens, conditioned air leaks into wall cavities and crawlspaces, and the system pulls in whatever is in the basement, including whatever condensation has been growing down there. Our repair work in Thompsonville focuses on those old metal systems: resealing seams, reattaching disconnected branches, and replacing sections that have rusted through or collapsed. Every repair is backed by a written guarantee. The full scope is on the Air Duct Repair in Thompsonville page.

Condensation-related mold treatment in unconditioned basements also pushes a job higher. Whatever the number, it is put in writing before any work begins, and it doesn’t change at the end.

What Thompsonville Customers Say
"Tech arrived with a badge and a printed sheet of what he'd be doing. Ran a camera through the main trunk before and after so I could see the dust difference. Vents smell cleaner already."
- Gina R."Priced by the system, not by the vent, and he told me up front. No pressure to add the sanitizer and I said no without any fuss."
- Faith N."We had construction dust packed into every register after a remodel. They sealed off the returns, used negative pressure, and left the floors cleaner than they found them."
- Paul E.
