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 typically runs $550 – $1,500 for a whole-home system, depending on the home’s age and duct layout. Most Norwalk jobs take about 4 to 6 hours, and we schedule them in a single visit. Coastal humidity, older housing stock, and the mix of forced-air systems across the city mean Norwalk ductwork rarely looks like the textbook examples other companies quote from. Call (737) 727-2314 for a written, line-item price before any work starts.
Why Norwalk Homes Are Different
Norwalk’s housing stock is a patchwork. You’ll find 1950s capes in Broad River with original metal duct runs, 1970s raised ranes in Wolfpit, and newer construction up off Route 7 near the Wilton line. Each one ages differently. The salt air off Long Island Sound works its way into crawlspaces and basements, which means fine corrosion dust in older registers. Homes near the Silvermine River or the Norwalk River carry higher indoor humidity through summer, and that moisture binds dust to duct walls in a way simple vacuum passes can’t remove. It takes brush agitation and negative-pressure extraction – that means the loosened debris goes straight into a HEPA-filtered vacuum, not back into your living room.
What really sets Norwalk apart is terrain. Steep lots off Bayne Street and along Fillow Street mean long, angled duct runs that collect debris unevenly. Split-level homes dominate in some neighborhoods, so we routinely find a branch line or two that has been ignored for years simply because it’s awkward to reach. Our technicians run Rotobrush brush systems and Nikro HEPA vacuums to handle exactly those runs, and they document every register with before-and-after photos.
Our Main Norwalk Services
Norwalk homeowners call us most often for dryer vent work and full duct cleaning. HVAC cleaning runs a close third, especially in fall before heating season. Here is how each job works in Norwalk.
Dryer Vent Cleaning in Norwalk
A clogged dryer vent is a fire hazard, and Norwalk’s older laundry rooms often vent through long horizontal runs or up through a second floor. That is a harder push for a dryer’s own blower and a fast way to accumulate lint. We clean the full run from the dryer to the exterior cap, clear the termination point outside, and verify airflow with a manometer. Dryer Vent Cleaning in Norwalk gets its own page with pricing and what the job includes.
Air Duct Cleaning in Norwalk
Whole-home air duct cleaning in Norwalk means cleaning the supply and return plenums, every accessible register, and the branch runs feeding each room. Coastal humidity and older framing make this a job where brush agitation matters. We use a Rotobrush rotary brush system for the runs, a Nikro HEPA vacuum for negative-pressure extraction, and Abatement Technologies containment around the register we are working so dust does not migrate. Air Duct Cleaning in Norwalk covers the full process, pricing, and what Norwalk-specific conditions we address.
HVAC Cleaning in Norwalk
HVAC cleaning goes a step beyond ducts. We clean the air handler, the evaporator coil, and the blower assembly. In Norwalk, condensate pans in humid basements collect a film that feeds microbial growth, and coils coated with dust drive efficiency down. We inspect the full cabinet, clean the coil with a commercial coil cleaner, and clear the condensate line. HVAC Cleaning in Norwalk goes into depth on the scope and cost of this service.

What pushes a Norwalk job toward the top of that range is usually access and duct age. Long runs through finished basement ceilings, buried branch lines in cathedral ceilings off West Norwalk, or ducts that have never been cleaned and carry a heavy accumulation all add labor time. What does not change is our price: we hand you a written total before a single register is opened, and that is the price you pay, whether the job finishes in three hours or six.
