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.
Fast, Reliable Air Duct Cleaning Across Norwalk
Air duct cleaning in Norwalk typically costs between $425 and $850 for a full single-family system, with most jobs completed in one visit. We’re CleanRun Air Duct Cleaning, and we’ve been documenting every duct run we clean since 2013. Norwalk’s specific conditions, from the I-5/I-605 freight corridor to decades-old attic ductwork, make this a different job than what homeowners in coastal cities face. Call (806) 606-6902 and you’ll get a written price before any work starts.
We know Norwalk’s neighborhoods. We know the tract homes off Alondra Boulevard and the older builds near Norwalk Boulevard. We know what gets pulled out of ducts near the Santa Fe Springs industrial border versus what we find a few miles south. That local knowledge means we arrive knowing what to look for, not hoping to figure it out after we open a register.
Why CleanRun Air Duct Cleaning Is Norwalk’s Preferred Air Duct Cleaning Company
We are not a franchise operation. CleanRun is independently owned and operated under the Haven Standard, led by Tomas Reyes, who has built this company since 2013 around a simple principle: show the customer what’s actually inside their ducts, in writing, with photos. When we work in Norwalk, we bring the same documented record we’ve delivered on more than 52,000 homes.
One thing sets us apart in this market: we hand you a written scope and price before a single panel comes off. That’s Haven Standard Clause 1. No technician arrives and “discovers” a higher price once the van is parked on your street near Excelsior Drive or anywhere else in Norwalk. The price we quote is the price. Every time. And when the job is done, you get a Documented Photo Record of every duct run, before and after, as a standard deliverable. You don’t have to trust us. You can look.
Tomas Reyes has built CleanRun’s reputation on the 365-Day Done Right Promise. If the work isn’t right, we make it right, and that’s backed in writing on every job, not buried in a footer. Norwalk homeowners call us because they’ve researched their options and they want evidence, not a sales pitch. We give them the evidence.
Our Air Duct Cleaning Services in Norwalk

Residential Duct Cleaning
Most Norwalk homes were built between the mid-1950s and early 1970s. That means the forced-air duct systems you’re breathing through have been in place for five or six decades. We clean the full supply and return runs, removing decades of accumulated debris, including the fine particulate load that settles from the freight corridors. A full system cleaning in a typical three-bedroom Norwalk tract home runs $425 to $650.

Commercial Duct Cleaning
Norwalk has a significant commercial presence along Firestone Boulevard and near the civic center. We handle commercial duct systems for offices, retail spaces, and light industrial facilities. Pricing for commercial work depends on square footage and system complexity, but a small commercial system in Norwalk typically starts around $700 and runs upward based on the number of rooftop units and duct runs. Every commercial job gets the same written price before work and the same documented photo record after.

Supply Duct Cleaning
Supply ducts are the runs that push conditioned air into your Norwalk home. In our experience with houses near the I-5/I-605 interchange, these ducts carry the heaviest diesel-soot loading. The supply side is also where we most often find cracked boot seals in Norwalk because those connections sit in attics that hit 140°F in summer. We clean the supply runs with negative-pressure extraction and agitation, then photograph every segment so you can see the result. Supply duct cleaning alone in Norwalk runs $200 to $350 for most homes.

Return Duct Cleaning
Return ducts pull air back to the furnace. When returns leak in a Norwalk attic, they actively draw in hot, polluted attic air and send it through your system. We find this constantly in older tract homes where the return plenum has separated from the main trunk. Cleaning the returns and sealing those connections addresses both the debris and the infiltration. Return duct cleaning runs $180 to $300 for a typical Norwalk single-family system.

Full System Cleaning
This is the job we recommend for most Norwalk homes, and it’s the one that delivers the most dramatic difference. We clean the supply and return runs, the main trunk line, the plenum, and the registers. We include video inspection of the entire system before and after. In Norwalk, a full system cleaning for a typical 1,200 to 1,800 square foot home runs $500 to $850. That’s a written price, agreed before we start, with no per-vent add-ons and no upsell pressure at the door.

Video Inspection
We offer standalone video inspection for Norwalk homeowners who want to know what’s in their ducts before committing to cleaning. The camera shows us exactly what we’re dealing with: a 3-inch debris build-up at the first elbow, a separated return plenum, a cracked boot pulling attic air. You see the same footage we see. A video inspection in Norwalk runs $95 to $150, and if you proceed with cleaning, we credit that amount toward the job.

We work with the equipment that outlasts the job. Our crews run professional-grade tools from Rotobrush and Nikro, with Abatement Technologies HEPA filtration on negative-pressure extraction, plus Honeywell and Aprilaire components when systems need filtration or humidification upgrades. We don’t use shop-vacs with a brush taped to the end. The equipment matters because the greasy diesel-soot film we find in Norwalk ducts won’t release with a light brushing. It takes agitation and genuine negative-pressure extraction. When you see Rotobrush or Nikro on the truck, you know the job will be done to NADCA standards.
Common Air Duct Cleaning Problems We See in Norwalk Homes

- Diesel-soot film on duct interiors. The convergence of the I-5 and I-605 corridors, combined with the Santa Fe Springs industrial zone just north of Norwalk, pushes fine carbon particulates into local ductwork. This film is greasy and stubborn. It doesn’t vacuum out. It requires negative-pressure source removal with agitation tools to break the bond.
- Cracked duct boot seals in high-heat attics. Norwalk’s inland position means attic temperatures routinely exceed 140°F from June through September. That heat degrades the mastic seals at duct-to-register connections. When those seals crack, the system actively pulls super-heated, particulate-heavy attic air into your living space. A filter change won’t fix it.
- Deteriorated flex duct in original systems. Many Norwalk homes still run their original or minimally-upgraded flex duct from the 1960s and 1970s. The liner breaks down over decades, sending fiberglass particles into the air you breathe. We document this with before photos and explain what replacement or sealing options make sense.
- Shared dryer vent stacks in older apartment buildings. Norwalk has thousands of multi-family units, many with shared dryer vent runs. One clogged unit backs up into neighbors. These buildings require coordinated access and scheduling, and we handle that coordination with property managers across Norwalk, from Cerritos College-adjacent rentals to complexes near the 605.
The Norwalk Freight-Corridor Dust Problem
Here’s the thing that makes Norwalk different from Cerritos or Bellflower. Norwalk sits at the convergence of two of Southern California’s heaviest freight corridors, the I-5 and the I-605, with the dense industrial zone of Santa Fe Springs directly on its northern border. Prevailing winds push diesel exhaust and industrial VOCs toward this pocket of the LA Basin. What that means for your ductwork is simple: homes here accumulate diesel exhaust particulates, industrial VOCs, and fine carbon soot in their ductwork at rates distinctly higher than neighboring coastal or purely residential cities. Every air duct cleaning call in Norwalk is fundamentally a freight-pollution and industrial-adjacency problem, not just a dust problem.
We learned this pattern working in Norwalk homes near the interchange. On a 1963 tract home a few blocks from the I-5/I-605 merge, our technician removed a supply register to find a thin, greasy black film coating the duct interior, a diesel-soot signature from the prevailing winds. We ran a full negative-pressure cleaning with HEPA filtration, agitated the source removal from the supply and return ducts, then sealed cracked boot connections that had been pulling super-heated attic air into the living space. The homeowner reported the musty, exhaust-like odor was gone within a day.
That’s why generic air duct cleaning doesn’t fully solve the problem in Norwalk. A DIY duct cleaning or a cheap shop-vac job won’t remove the greasy diesel-soot film bonded to duct walls. Only negative-pressure source removal with agitation tools can break that bond. And cracked duct boot seals in 140°F attics actively pull polluted, super-heated attic air into the living space. A basic filter change won’t fix that infiltration. This is why we emphasize Full System Cleaning, Supply Duct Cleaning, and Video Inspection for Norwalk homes. The job here is different. The approach has to be, too.

FAQs - Air Duct Cleaning in Norwalk
The greasy black film is a diesel-soot signature from the I-5 and I-605 freight corridors plus the Santa Fe Springs industrial zone just north of Norwalk. Standard vacuuming won’t remove it because the soot bonds to the duct wall. It requires negative-pressure source removal with mechanical agitation to break the bond and extract the particulate load. Then the duct interior is photographed so you can see the difference. Call (806) 606-6902 for a written price on the full system cleaning that addresses this.
We plan our truck equipment loads for Norwalk street layouts. Older tract neighborhoods near Norwalk Boulevard and Alondra Boulevard often have narrow streets and limited curb parking. Our crews carry portable negative-pressure units that fit through standard gates and work from compact setups. We’ll confirm parking specifics when we schedule so the equipment access is sorted before the crew arrives.
Yes. Many older Norwalk apartment and condo buildings share dryer vent stacks through a common riser. When one unit’s lint load builds up, backpressure pushes lint and exhaust into adjacent units. You may smell dryer exhaust in your unit even if your vent looks clean. Resolving it requires coordinated access and scheduling with property management. We handle that coordination and document the stack’s interior before and after cleaning.
Norwalk’s inland location means summer attic temperatures regularly exceed 140°F. Coastal cities like Long Beach and Seal Beach run cooler attics, so their duct mastic and flex liners degrade slower. In Norwalk, the heat weakens mastic seals at duct boots, cracks liners, and accelerates the wear on flex duct installed decades ago. The air quality is also different: Norwalk’s position in the southeastern LA Basin carries a heavier particulate load per South Coast AQMD data. The combination of heat stress and particulate load means Norwalk ductwork fails faster.
NADCA sets the standard for source-removal cleaning, which means removing debris from the duct system, not just loosening it. We work to NADCA standards on every job: negative-pressure extraction, agitation of all interior surfaces, and visual verification via video inspection. You receive a Documented Photo Record of every duct run before and after, so you can see the work was actually done, not just told it was. If you want a second opinion on any written estimate, bring it to us. We’ll put our number next to it in writing.
