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.

AfterAir Duct Cleaning Company in Derby, CT
Air duct cleaning in Derby costs $425-$825 for a whole-home system in a typical two- or three-decker, with most jobs falling around $500-$650. The work usually takes 2-4 hours, and we give you a written price before a single vent is touched. Derby’s valley-floor location and 80-130-year-old housing stock mean the ductwork here runs dirtier and wetter than what you’d find in newer hilltop towns like Shelton. If you’ve never had your ducts cleaned and your home predates forced-air heating, there’s a good chance the system is carrying decades of moisture-laden debris. Call (469) 972-3151 for an estimate.
Why Derby Homes Are Different
Derby sits at the bottom of the Naugatuck River Valley, right where the Naugatuck meets the Housatonic. That geography creates a natural cold-air and moisture trap. Humidity runs higher here than in Shelton or Seymour, and that moisture finds its way into ductwork through old seams and poorly sealed joints. On top of that, most of Derby’s housing stock was built for mill workers between 1890 and 1940. The original heat was steam radiators. Forced-air systems were retrofitted later, often with ductwork shoehorned into wall cavities and floor chases that were never designed for it. The result is undersized, poorly insulated duct runs that pull humid air continuously. In Derby’s dense rental corridors, a single neglected duct system in a two- or three-family home can push particulates and mold spores into multiple tenant units at once. That shared-duct contamination pattern is a Derby-specific problem. It rarely shows up in the single-family suburban stock of nearby towns.
Our Main Derby Services
Most Derby homeowners call us for one of two things: cleaning the ducts that move heated and cooled air through the house, or clearing the dryer vent that pushes hot, lint-filled air outside. Each service has its own Derby page with pricing, details, and local notes.
Air Duct Cleaning in Derby
Derby’s retrofitted ductwork tends to be tight, oddly routed, and sealed with materials that have degraded over decades. That means more dust, more moisture, and more mold spores moving through the living space. Our Air Duct Cleaning in Derby service uses negative-air extraction to pull contaminants out of the system rather than push them around, which matters in older homes where duct leaks can release loosened debris into walls and floor cavities. Brush agitation dislodges the compacted layer stuck to duct walls, then the negative-pressure unit carries it out. We walk you through what we found and what we did before we leave.
Dryer Vent Cleaning in Derby
In Derby’s older multi-family homes, dryer vent runs are often long, convoluted, and shared through wall cavities. That buildup is more than a fire risk; it forces the dryer to work harder and dry slower, which drives up energy bills and shortens the life of the machine. Our Dryer Vent Cleaning in Derby service clears the full run from the dryer connection to the exterior exhaust point, including the lint trap bypass and the exterior hood. We use professional-grade brushes and high-pressure air to remove the packed lint, and we check the vent termination for damage while we’re there.

Brands We Service in Derby

Pricing for Air Duct Cleaning Company in Derby, CT
| Service | Typical range in Derby |
|---|---|
| Whole-home air duct cleaning (single-family) | $425-$825 |
| Whole-home air duct cleaning (two- or three-decker unit) | $425-$650 |

What pushes a Derby quote toward the top of that range is access. In older two- and three-deckers, duct runs are often buried in finished floor cavities or tight chases, which means more time on the job and more care to avoid disturbing original plaster and trim. The written price we give you before we start is the price you pay. No per-vent add-ons, no door-step revisions. We put that in writing on every single job.

What Derby Customers Say
"Bought an older home and the previous owners had pets everywhere. After Kestrel did the ducts the stale smell was just gone. On time, quick, and they showed me the filter they pulled."
- Preston Ngata"Our dryer was taking two cycles to dry a load. They cleaned the vent and pulled out a frightening amount of lint. Dries in one cycle now and honestly I feel better about the fire risk."
- Marcus Lee"Set up an appointment for the whole house plus the dryer line. They called the morning of to confirm, showed up in the window, and showed me pictures of the gunk they pulled out. Worth it."
