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 Cleaning Across Norwalk
Air duct cleaning in Norwalk, CT typically runs between $395 and $780 for a full system, depending on home size, the number of duct runs, and how much of that diesel-soot film has built up inside the plenum. Most jobs in Norwalk are completed in one visit, with a written price agreed before a single panel comes off. Our crews know this city’s housing stock well: the post-WWII tract homes, the 1960s ranches with unconditioned attics, and the condo conversions where ductwork threads through shared spaces. Call (806) 606-6902 and we’ll give you a number in writing before anything happens.
We’re CleanRun Air Duct Cleaning, and we’ve been documenting what’s actually inside ductwork since 2013. Serving Norwalk means understanding what the I-5 and I-605 do to the air inside your home. More on that below.

Our Air Duct Cleaning Services in Norwalk
Residential Duct Cleaning
Norwalk’s housing stock is dominated by single-family tract homes built between the mid-1950s and the early 1970s. Many still run their original forced-air duct systems through unconditioned attics, where temperatures routinely pass 140°F in July and August. That heat degrades flex duct liner and cracks the mastic seals at joints, pulling attic air into the living space. Our residential work starts with camera inspection, then negative-pressure source removal with agitation tools sized for older duct runs. We don’t just vacuum registers; we pull the debris and the soot film from inside the run itself.
Commercial Duct Cleaning
Norwalk’s commercial spaces sit close to Santa Fe Springs’ industrial zone, which means restaurant supply ducts, office HVAC systems, and retail plenums here carry a heavier particulate load than similar buildings in Stamford or Fairfield. We clean commercial systems on schedules that make sense for the exposure: quarterly for high-traffic food service near the I-605, semi-annual for offices along Main Avenue. Every job includes the same written price and photo record we give homeowners.
Supply Duct Cleaning
Supply ducts carry conditioned air from the furnace to your registers. In Norwalk tract homes, these are often original galvanized runs that have accumulated decades of dust, skin cells, and that signature diesel-soot film. Cleaning supply ducts properly requires sealing both ends and running negative-pressure extraction, not just poking a brush into the register boot. We do it the right way because half-cleaning a supply run is exactly how the film comes back in three weeks.
Return Duct Cleaning
Return ducts pull air back to the furnace. In a 1963 ranch near Excelsior High, our crew found the original flex duct in the return path had failed entirely in the attic. The system was pulling 140°F attic air loaded with freeway soot through cracked boot seals. We performed negative-pressure source removal with agitation tools, re-sealed the boots, and confirmed with camera inspection that the greasy black film was gone. That’s return duct cleaning in Norwalk: not just vacuuming, but sealing the infiltration points that re-contaminate the air within days.

Common Air Duct Cleaning Problems We See in Norwalk Homes
- Diesel-soot film at the I-5/I-605 convergence. Prevailing winds push freeway exhaust into this pocket of the LA Basin, and the result is a greasy black film coating duct interiors near the interchange. A vacuum-only cleaning leaves this film behind, and it re-contaminates within weeks. Source removal with HEPA filtration is the only fix.
- Failed flex duct in 140°F attics. Norwalk’s summer attic heat degrades flex duct liner until it splits. The system then pulls super-heated, particulate-laden attic air into the living space. Damaged sections need replacement, not just cleaning.
- Cracked duct boot seals. The seal where a duct boot meets a register is a common failure point in 60-year-old tract homes. Cracked boots actively draw attic air. We re-seal boots as part of a full cleaning, and document the before and after with the camera.
- Shared dryer-vent stacks in condo conversions. Many Norwalk condo conversions route dryer vents through a shared stack. A clog in one unit creates back-pressure in others, and the lint pathway becomes a fire hazard. We inspect the full run and clean the shared stack when access allows.
Pricing for Air Duct Cleaning in Norwalk, CT
Here are the numbers for Norwalk’s market, as of early 2026. A typical full residential system (10-15 duct runs) runs $395-$620.

Homes with documented diesel-soot contamination requiring extended HEPA source removal run $550-$780. The written price you get before work starts is the price you pay.

Our answer is Haven Standard Clause 1: one flat price per system, in writing, before a panel comes off. And you get before-and-after photos of your own ducts, not stock images.

FAQs - Air Duct Cleaning in Norwalk
Norwalk sits at the convergence of the I-5 and I-605, with Santa Fe Springs’ industrial zone directly to the north. That freight-traffic exposure leaves a diesel-soot film in ductwork that coastal cities like Long Beach simply don’t see at the same rate. It’s not just dust; it’s exhaust particulate and industrial VOCs that settle by the pound in aging tract-home duct systems. Removing it at the source takes HEPA filtration and agitation, not just a vacuum pass. Call (806) 606-6902 and we’ll show you what’s inside your ducts before we quote a number.
Yes. Negative-pressure source removal with agitation tools cleans from the register openings, without cutting into drywall. In most of Norwalk’s tract homes, access is through registers and the plenum at the furnace. If we find collapsed flex duct or a failed seal that needs replacement, we’ll show you the camera footage and give you a separate written price before any additional work. No walls get opened unless you approve it in writing first.
The quickest check is a visual one: if your dryer vent exits through a wall or ceiling without a dedicated exterior termination you can see from outside, it may be running through a shared stack. In many Norwalk condo conversions from the 1970s and 1980s, multiple units tie into a single vertical vent run. A camera inspection of your vent line will confirm the path and show where your air is actually going. Clogs in a shared stack affect every unit attached to it, so a professional cleaning protects more than just your laundry room. Call (806) 606-6902 to schedule a camera inspection.
Yes, directly. When attic temperatures pass 140°F, the differential pressure between an unconditioned attic and your air-conditioned living space increases, which means any crack, gap, or failed seal draws attic air in faster. If we clean your ducts but don’t address a cracked boot seal, the contamination returns within weeks. That’s why our Norwalk jobs include seal inspection and re-sealing as standard, documented with before and after photos.
It removes what’s already inside your ductwork, which is the portion of the pollution load you can control. The diesel soot, industrial dust, and fine particulate that has settled in your ducts gets extracted at the source with HEPA filtration. What continues to enter from outside is a separate issue; we recommend a high-efficiency media filter from Aprilaire or Honeywell if you’re concerned about ongoing infiltration. But the lead contamination in your air supply right now? That’s what cleaning addresses, and we’ll show you the before and after photos to prove it left. Call (806) 606-6902 for a written estimate on your system.
