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 typically costs $450 – $850 for a full residential system, and the honest answer to “how often” is every 5 – 7 years for most homes here. That range assumes a one-family house with a single air handler, all supply and return runs included, and a camera inspection before and after. We’re Cardinal Air Duct Cleaning, part of the Relay Home Co. family founded in 2005, and our crews work throughout Norwalk from Rowayton to Broad River. If you want a written price before anyone touches a duct, call (737) 727-2314.
Why Cardinal Air Duct Cleaning Is Norwalk’s Preferred Air Duct Cleaning Company
Norwalk homeowners call us for one reason more than any other: we hand you a written price before the first duct is opened, and that number doesn’t move. No per-vent surprise, no “we found extra flex runs” upcharge at the door. Every booking runs through The Relay Standard, which means a live trackable arrival window on your phone, before-and-after photos of your own ducts, and a digital invoice you can pay by link. That is the whole transaction, start to finish.
Our technicians are background-checked and uniformed. You’ll know the tech’s name before they pull into your driveway off Route 7 or Westport Avenue. They run professional-grade equipment: Rotobrush rotary brush systems for agitation, Nikro HEPA vacuums for negative-pressure extraction, and Abatement Technologies containment units where needed. This is not a shop-vac hooked to a truck. The work is backed by the 365-Day Done Right Promise. If the work isn’t right within 365 days, we return and correct it at no charge. Omar Haddad leads our Norwalk operations, and he holds every job to that standard without exception.
Residential Air Duct Cleaning in Norwalk
Residential Air Duct Cleaning for a Norwalk home starts with a camera inspection of the full system, not just the registers you can see. That inspection tells us whether you’re dealing with original sheet-metal runs from a 1960s cape or flexible insulated duct added during a 2000s renovation, and it determines the cleaning method. Most Norwalk houses in the Silvermine and Cranbury areas have a mix of both, which is exactly why per-vent pricing collapses here. One flat price per system, agreed before work starts, based on what the camera actually shows. A standard single-system home in Norwalk runs $450 – $650; larger homes with long trunk runs or finished basement access panels run $700 – $850.
The Camera Inspection First
Before any brush touches a duct, we scope the trunk line, branch runs, return drops, and air handler. In Norwalk’s older homes, this step catches crushed flex in crawlspaces and disconnected joints that would otherwise get “cleaned” as if intact. You get a look at the before images.
Rotary Agitation and HEPA Extraction
For original sheet-metal ductwork, we run a Rotobrush system under negative pressure, meaning loosened debris flows straight into a Nikro HEPA-filtered vacuum, not back into your living room. The blower motor and wheel get cleaned too, because skipping them is how dust returns within three weeks.
Commercial Air Duct Cleaning in Norwalk
Commercial Air Duct Cleaning in Norwalk covers office buildings, medical suites, retail spaces, and restaurants from Route 1 to Main Street. These systems run longer hours than any home, pulling in parking-lot dust off I-95 and humidity off Long Island Sound, which accelerates buildup on coils and inside return plenums. Most commercial jobs in Norwalk run $1,200 – $3,500 depending on square footage, number of rooftop units, and whether the building has kitchen exhaust or high-MERV filtration in play. We provide a written price per system after a walkthrough and camera scope, and the 365-Day Done Right Promise covers commercial work exactly as it covers residential.
After-Hours and Weekend Scheduling
We schedule commercial work around your operating hours, including nights and weekends, so a restaurant or clinic isn’t disrupted during business. Norwalk’s commercial corridors off West Avenue and East Avenue are familiar routes for our crews.
Containment for Occupied Spaces
When a medical office or retail space needs cleaning while adjacent tenants stay open, we use Abatement Technologies containment units to keep disturbances localized. The written guarantee on every repair and a free second visit if a repair fails applies whether it’s one rooftop unit or twelve.
Trusted Brands We Service in Norwalk
Norwalk homeowners run everything from 40-year-old oil-fired furnaces in Split-level ranches to new high-velocity systems in SoNo townhomes. Our technicians service and clean around Aprilaire media filters, Guardsman filter racks, and Honeywell electronic air cleaners. We stock common filters and access panels locally so a routine cleaning doesn’t stall waiting on a part. If your system has a Rotobrush-cleaned Aprilaire cabinet or an Abatement-ready return plenum, we know the tolerances and the correct cleaning sequence. No guessing, no forced parts sales.
Common Air Duct Cleaning Problems We See in Norwalk Homes
- Mixed duct materials on one air handler. A 1958 ranch in Wolfpit gets a second-floor addition with flex duct, and suddenly one system has two cleaning profiles. Per-vent pricing collapses here; flat pricing per system is the only honest approach.
- Coastal humidity and surface moisture. Homes within a mile of Long Island Sound in Rowayton or East Norwalk pull damp air into return ducts, where dust turns to a pasty film. We dry and verify after cleaning, because wet debris left behind re-adheres fast.
- Skipped air handlers from prior cleanings. A blower wheel caked in debris re-contaminates every branch run within weeks. We see this constantly after low-bid cleans that only touched visible registers.
- Crushed flex in crawlspaces. Norwalk’s hilly lots in Silvermine and Cranbury mean crawlspaces get wet, flex duct sags, and nobody notices until a camera goes in. We inspect before we clean, not after.

FAQs About Air Duct Cleaning in Norwalk
Every five to seven years for most Norwalk homes. Homes within a mile of the Sound, where return ducts pull damp air, skew closer to five. If you run a MERV 11 or higher filter and change it monthly, you may stretch to seven. If you have pets, recent renovations, or a smoker in the house, shorten the interval. Call (737) 727-2314 and Omar Haddad can help you decide if you’re due or if another year is fine.
One flat price per system includes the camera inspection, all supply and return runs, the trunk line, air handler, blower wheel, and before-and-after photos. Per-vent pricing breaks down in Norwalk because most homes here have mixed duct materials, original sheet metal and added flex, on the same handler. A per-vent quote treats every run as identical, and the moment the tech finds a second material, the price jumps. We quote the whole system once, in writing, before work starts. Call (737) 727-2314 for a flat-price estimate.
Yes. A 1960s cape in Cranbury with original galvanized steel ducts needs rotary agitation with a Rotobrush, while the added flex runs from a 2000s renovation need contact vacuuming at lower agitation. A single method across both materials either under-cleans one or risks damage to the other. That’s why we camera-inspect before choosing, and why we never quote per vent. Call (737) 727-2314 and we’ll walk you through what your house has.
We schedule by appointment with a live trackable arrival window, not a same-day guarantee. Norwalk dispatch runs through our Hartford coordination office, so we can usually offer a window within a few days depending on season. A live person answers 24/7, so call (737) 727-2314 and we’ll give you an honest timeline. No voicemail loops.
MERV 11 pleated filters are the sweet spot for most Norwalk homes. MERV 13 catches more fine particulate, but in Norwalk’s coastal humidity it can restrict airflow on older furnaces and increase static pressure. If your system handles MERV 13 without strain, go ahead. If not, MERV 11 plus regular duct cleaning every five years keeps dust down without choking airflow. We stock Guardsman and Aprilaire media filters in common sizes. Call (737) 727-2314 if you want a filter check during your cleaning.
