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 Repair Across New Canaan
Air duct repair in New Canaan typically costs between $450 and $2,800 depending on whether we’re sealing a single leaking joint or rebuilding a return-air path on a mid-century modern with three air handlers. Most repair jobs in town are completed in one visit, though homes with multiple systems and long attic runs sometimes need a second morning to finish camera inspection and sealing. We know New Canaan’s housing stock because we work in it every week: the 1950s estate homes off South Avenue, the Harvard Five experiments off Ponus Ridge, the big center-hall colonials off Carter Street. Call (980) 447-2498 and you’ll get a real person who knows this town’s ductwork, not a call center reading from a script.
Why Linden Air Duct Cleaning Is New Canaan’s Preferred Air Duct Repair Company
New Canaan homeowners call us because we document what we find. Every repair job includes camera inspection footage from inside your ducts, which matters when the problem is a thirty-year-old flex duct collapse you can’t see from the basement. Marcus Veale leads our crew, and he’s built our reputation on showing homeowners exactly what’s behind the drywall before we touch it.
We’ve worked on enough New Canaan homes to know what’s normal here and what isn’t. When we open a supply register in a 1970s estate near the Waveny Park side of town and find a collapsed flex run, we know it’s probably original to the house. When we find a radiant-era retrofit off Ponus Ridge with no return-air strategy, we know how to rebuild it. That’s not generic HVAC knowledge. That’s New Canaan knowledge.
The Threshold Standard applies to every technician who comes to your door. You get the tech’s name and photo before the visit. The tech shows a photo ID badge at the door. Background-checked, identity-verified, and driving a marked vehicle. No surprises about who’s walking into your house.
Every repair comes with a written price before we start and a written guarantee covering the work for 365 days. If a covered repair fails, we come back at no charge. That’s the Done Right Promise, and it’s on paper every single time.
Air Duct Replacement in New Canaan
Air Duct Replacement in New Canaan usually means pulling out collapsed or torn flex duct in homes built between the 1950s and 1980s, when builders ran long lengths of flex through unconditioned attic spaces above rooms like the family room or primary suite. A single-run replacement in a New Canaan colonial typically runs $350 to $900, while a full-system replacement across a three-zone estate home with multiple air handlers can reach $5,000 to $10,000 depending on linear footage and access.
When Replacement Beats Repair
If camera inspection shows a flex run has collapsed flat or torn along its entire length, patching it would be throwing money away. We tell you when a repair will hold and when it won’t. Nobody wants to pay twice for the same run.
Replacing Runs in Hard-to-Reach Attics
New Canaan attics are tight. Low-pitch roofs, foam insulation retrofits, and decades of stored belongings make access genuinely difficult. We quote replacement work based on what we can see during the estimate, and we document everything with before-and-after photos of your own ducts.
Ductwork Repair in New Canaan
Ductwork Repair in New Canaan is most often about sealing the gaps that freeze-thaw cycles create in unconditioned attic and crawl space runs. New Canaan’s winters swing from single digits to the 40s, and that movement shifts hangers and separates joints. A single leaking joint sealed with mastic and mesh typically runs $180 to $400, while reconnecting multiple separated trunk lines and rebuilding a return-air path runs $700 to $2,800, especially on larger homes with long runs.
Sealing Leaks That Pull Attic Air
When a supply duct separates in an unconditioned attic, it doesn’t just leak heated or cooled air. It pulls attic dust, insulation fibers, and whatever else is up there into your living space. We seal with mastic and mesh, not duct tape, and we pressure-test after the job.
Rebuilding Return-Air Paths
The mid-century modern homes off Ponus Ridge and South Avenue frequently have supply trunks but no functional return-air design. That means unfiltered envelope air gets drawn through gaps in the building shell directly into the system. Rebuilding a return path is real engineering work, and we document it with camera footage before and after.
Trusted Brands We Service in New Canaan
We work on all major duct system components, including equipment from Rotobrush for cleaning and Abatement Technologies for air-quality products. Our trucks carry common fittings, mastic, collars, and flex duct in the sizes used locally, so most New Canaan repair jobs finish the same day. If your system has a specific brand of zoning damper or air handler, tell us when you call. We stock what this town’s older homes actually use.
Common Air Duct Repair Problems We See in New Canaan Homes
- Collapsed original flex duct in 1950s – 1980s estate homes. Long runs installed during the commuter-boom building era are now brittle and collapsed. Camera inspection shows it in minutes.
- Freeze-thaw movement in unconditioned attic runs. New Canaan’s winter temperature swings separate duct hangers and joints every season. Gaps pull insulation fibers and attic dust into the airstream.
- Radiant-era retrofits with no return-air strategy. Especially off Ponus Ridge and South Avenue. These homes draw unfiltered air through envelope gaps for decades, a contamination pattern we rarely see in Darien or Wilton colonials.
- Oversized systems running at low duty cycles. Big homes with summer owners away mean humid air sits in ductwork longer, promoting mold growth inside runs that were never designed for those conditions.

FAQs About Air Duct Repair in New Canaan
Because New Canaan has a much higher share of large, custom-built estate homes with multiple air handlers, long attic runs, and difficult access. A Norwalk cape or a Darien colonial might have one air handler and short, accessible duct runs. A New Canaan home on a wooded lot off Carter Street might have three systems and original flex that runs the length of an attic you can’t stand up in. That’s more labor hours, more material, and more care in access. The price reflects the actual work, and we put it in writing before anything starts. Call (980) 447-2498 for a quote specific to your house.
You should receive camera inspection footage from inside your ducts, before and after photos of the specific runs we worked on, a written description of what we found and what we did, and the written guarantee covering the repair for 365 days. Anything less means you’re taking a contractor’s word for work you can’t inspect. We won’t ask you to do that.
Yes. This is a known pattern in the Harvard Five homes and their contemporaries. The original radiant-to-forced-air conversions added supply trunks without adding return runs, so the system pulls unfiltered air through gaps in the building envelope. We camera-inspect the entire system, map what’s actually there, and rebuild a functional return-air path. On a Ponus Ridge mid-century modern with three air handlers and original flex duct, our tech found exactly this, and we reconnected shifting joints above the flat roof, rebuilt the return path, and handed the homeowner documentation showing what was happening behind their walls for the first time since the retrofit.
New Canaan sits in a dense hardwood forest corridor, so spring pollen from oak, birch, and maple loads heavily into outdoor air intakes. Humid summers mean moisture sits in ductwork, especially in large homes that run at low duty cycles when owners are away. That combination means ducts here need sealing and repair more urgently than in drier, less wooded areas. When we seal a leak, we’re not just fixing airflow, we’re stopping pollen and moisture from being pulled into the system.
We service all standard sheet-metal and flex duct systems, including zoning dampers, air handlers, and return-air paths.

If your New Canaan home has a specific brand of air handler or zoning system, mention it when you call (980) 447-2498 and we’ll confirm coverage before we schedule.
