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 Norwalk, CT
Air duct cleaning in Norwalk runs between $380 and $650 for a full single-system home, and the condition of your ductwork here has a lot to do with where this city sits on the map. Norwalk is boxed in by the I-5, I-605, and SR-91 freeways, which means fine diesel soot from thousands of daily truck trips ends up inside residential duct systems faster than in almost any other part of Los Angeles County. We’re the air duct company that gives you a written price before any work begins, and you can call (980) 447-2498 for a free estimate today.
Why Norwalk Homes Are Different
Most homes in Norwalk were built between 1950 and 1975, and the typical house is a ranch-style tract home with its original sheet-metal ductwork still in place. That matters because ducts installed six or seven decades ago were sized and sealed for different equipment, and time has not been kind to the joints, tape, or insulation wrap. Homes built before 1978 often have degraded duct insulation, and in some cases asbestos-containing wrap around the ducts that has to be assessed before anyone runs a cleaning head through the system.
Then there’s the freeway factor. Streets east of Norwalk Boulevard, especially the tracts close to the I-605 corridor, get a steady diet of diesel particulate that works its way past window screens, through attic vents, and into the duct runs. Our technicians routinely find black, oily soot coating the inside of supply boots in homes where the homeowners run clean filters and keep the house tidy. The filter catches what reaches it, but the outdoor air that gets pulled into the attic through leaky duct joints never touches that filter at all. Santa Ana wind events make it worse by pushing fine particulates and wildfire smoke directly into the area from the east, and the low humidity that comes with those winds dries out older flex-duct connections, opening small leaks that pull attic dust and freeway-adjacent outdoor air straight into the supply stream.
Our Main Norwalk Services
Each has its own dedicated Norwalk page with full pricing and scheduling details.
Air Duct Cleaning in Norwalk
Full-system air duct cleaning in Norwalk uses negative-pressure extraction, which means the cleaning equipment pulls air backward through the ducts while we agitate the interior walls to loosen what has stuck there. In Norwalk homes, that buildup is heavier on the supply side than the return side because freeway-sourced soot gets drawn in through attic leaks before it ever reaches the filter. The job takes between three and five hours for a typical single-system ranch home, depending on how many registers it has. Full details, including what to expect from start to finish, are on the Air Duct Cleaning in Norwalk page.
Dryer Vent Cleaning in Norwalk
Dryer vents in Norwalk’s older homes are often the original rigid metal pipe, and in many cases they run much farther than modern building codes allow. A longer run means more surface area for lint to catch, and once lint builds past a certain depth, the dryer starts working harder and running hotter. Norwalk’s dry climate means the lint inside the vent bakes into a hard, brittle layer that does not fall away on its own. We clean the full length of the run with rotating brushes and confirm airflow before we leave. Details on the Dryer Vent Cleaning in Norwalk page.
Air Duct Repair in Norwalk
Duct repair in Norwalk usually means one of three things: reconnecting joints that have separated under settling, re-wrapping insulation that has deteriorated or been torn by rodents, or replacing sections of flex duct that Santa Ana dryness has degraded. Homes along the I-605 corridor tend to show faster joint failure because the constant traffic vibration, faint but continuous, works on the sheet-metal seams over time. Every repair we perform in Norwalk comes with a written guarantee, and if a covered repair fails within 365 days, we return and fix it at no charge. More on the Air Duct Repair in Norwalk page.

What Norwalk 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.
