Post-Construction Duct Cleaning
Full ductwork reset after renovation, addition, or new construction, removing drywall dust, joint compound, and sawdust that accumulates during framing and finish work in Norwalk homes.

To IICRC S520-2024, mold inside ductwork, coils, and air handlers is remediated with negative-air containment, EPA-registered antimicrobial treatment, and independent third-party clearance.
HEPA Filtration And Negative-Air
The prerequisite for any cleaning that meets the NADCA ACR-2021 standard is hospital-grade HEPA H13 filtration with negative-air containment, capturing 99.97% of particles at 0.3 microns at the source.
Rodent And Pest Decontamination
Ductwork decontamination after rodent intrusion, including droppings removal, carcass extraction, structural sanitization, and sealing of entry points to prevent recurrence in Norwalk attics and crawl spaces.

Every cleaning closes with EPA-registered antimicrobial on the evaporator coil, critical in Norwalk's coastal humidity.
What Dirty Ductwork Costs Your Norwalk Home
Most Norwalk homeowners don't think about their ductwork until allergies flare, energy bills climb, or a musty smell starts blowing out of the vents. Coastal humidity, older galvanized duct systems, and long supply runs in Fairfield County homes make buildup compound fast.
Dust, Dander And Pollen Buildup
Recirculating Through Every Room
The average Norwalk home cycles 40 pounds of dust through its ductwork every year. Without cleaning, it recirculates pet dander, pollen, and construction debris back into living spaces daily.
Mold Growth In Ducts And Coils
Long Island Sound Humidity Accelerates It
Coastal humidity condenses inside metal ductwork and on evaporator coils. Mold colonies grow on the inside of register boots and supply trunks, then aerosolize spores into every conditioned room.
Reduced HVAC Efficiency
Higher Bills, Shorter Equipment Life
A clogged duct system forces the blower motor to work harder, driving utility bills up 15 to 25% and cutting equipment lifespan in half. Clean ducts pay themselves back in the first two billing cycles.
Rodent And Insect Contamination
Droppings Aerosolize Through Supply Air
Norwalk's older Colonials and carriage houses on Wilson Point and Saugatuck Shores see seasonal rodent intrusion into attic ductwork. Droppings dry, pulverize in the airflow, and reach every bedroom.
Post-Construction Debris
Drywall Dust, Sawdust, Joint Compound
After renovation or new construction, ductwork accumulates drywall dust and joint compound that blows into living spaces for months. NADCA ACR-2021 source-removal post-construction cleaning is the only full reset.
Dryer Vent Fire Hazard
Leading Cause Of Laundry Room Fires
Clogged dryer vents cause roughly 2,900 home fires in the US every year per the US Fire Administration. A full vent cleaning to the exterior cap takes under an hour and eliminates the risk.

Why Norwalk Homes Need Professional Air Duct Cleaning
Norwalk's Long Island Sound humidity, older HVAC systems in pre-war homes, and long supply runs in waterfront estates create duct conditions that surface cleaning cannot solve. NADCA source-removal with coil treatment is the only full reset.

NADCA ACR Standard Source-Removal Cleaning
Our Norwalk crews follow the National Air Duct Cleaners Association ACR standard for source-removal, not surface-blow. Every duct branch is scrubbed under negative pressure with rotary brushes and HEPA vacuum collection, not just blown out with a leaf blower.
Full HVAC System Coverage, Not Just Registers
Most Norwalk air duct calls start because a competitor only cleaned the visible register boots. We clean the supply trunk, return trunk, air handler, evaporator coil, blower compartment, and dryer vent so the entire system is decontaminated, not just the first six inches.
Coil Treatment And Antimicrobial Fogging
Every cleaning closes with EPA-registered antimicrobial treatment on the evaporator coil and inside the air handler. This is critical in Norwalk homes where Long Island Sound humidity condenses on coils and mold returns within weeks without treatment.
Before-And-After Verification Photos
Every Norwalk air duct job closes with before-and-after photos inside every accessed duct branch and the air handler. You see exactly what we removed, the file becomes part of your home records, and it documents the condition for any future home sale.
Why We Don't Offer $69 Air Duct Cleaning In Norwalk
You've seen the ads. “Whole-house air duct cleaning, $69!” Those offers are bait-and-switch operations flagged by the BBB and the Connecticut Attorney General. The $69 gets a technician in your door with a shop-vac and a compressor hose. Once inside, “required” add-ons push the bill to $900 or more, for work that isn't actually to NADCA ACR-2021 standard.
What Happens On A $69 Job
- Shop-vac and compressor, no negative-air containment
- Mold "treatment" pressure-sell, $300+
- Coil cleaning suddenly $250 extra
- Sanitizer fogging pitched as "required," $200
- Final bill: $900 to $1,400, no photo verification
What You Pay For With Us
- Nikro HEPA negative-air equipment, not a shop-vac
- NADCA ACR-2021 source-removal on every register
- Before and after photos you keep
- Flat pricing from $1,299, no mid-job add-ons
- IICRC-certified technicians, insured, HIC.0702252
NADCA's own consumer advisory states that any quote under $500 for a full residential system is almost certainly a bait-and-switch. If a Norwalk homeowner is quoted $69 to $199 for whole-house cleaning, call (203) 674-9573 for an honest, itemized estimate instead.
What We Find In Norwalk Air Ducts
Norwalk runs from SoNo and Norwalk Center stock to waterfront estates on Saugatuck Shores and Wilson Point, where Sound humidity packs ducts with dust, so every job is done to the NADCA ACR-2021 source-removal standard with before and after photos.

Dryer Vent, Lint Cleared
In Norwalk, older Norwalk Colonials carry long dryer runs that load up with lint.
A flexible dryer duct slowly fills with lint until airflow is choked off. That restriction makes the dryer run hot and long, and a lint-packed run is a recognized fire hazard. Most homeowners never see it because the buildup sits inside the wall and roof run, out of sight behind the lint trap.
We clear the full run from the lint trap all the way to the exterior cap, working the line with a rotating brush and compressed air so the lint is pulled out rather than packed tighter. We check the transition hose, the wall and roof run, and the exterior flap, then confirm the cap opens freely under real airflow.
With the run cleared end to end, the dryer vents the way it is meant to, drying loads faster and reducing the fire risk a clogged line carries. We confirm airflow at the exterior cap before we leave and walk you through what we found and cleared.

Air Duct Cleaning FAQs
Clear, honest answers about NADCA cleaning, HVAC system service, dryer vent safety, and indoor air quality in Norwalk, CT.
Air duct cleaning in Norwalk starts at $1,299 to $2,000 per HVAC unit for a single-zone system following NADCA ACR-2021 source-removal standard. Multi-zone homes with 2+ HVAC systems run $2,500 to $4,000, and commercial spaces with kitchen exhaust included run $2,500 to $6,000. Dryer vent cleaning is free when bundled with air duct cleaning. Standalone dryer vent service starts at $249. Pricing depends on system size, duct length, accessibility, and whether mold remediation or antimicrobial treatment is needed. We provide a written estimate before any work begins.
Most single-zone Norwalk HVAC cleaning takes 3 to 4 hours. Multi-zone systems or long-run ductwork in waterfront estates on Saugatuck Shores or SoNo can take 5 to 7 hours. Dryer vent cleaning is typically under an hour when done as an add-on. The full cleaning is always finished in one visit.
The NADCA recommendation is every 3 to 5 years for most Norwalk homes, with more frequent cleaning for households with pets, allergy sufferers, smokers, or recent construction. Homes near Long Island Sound often benefit from 3-year cycles because coastal humidity accelerates coil and duct contamination. Dryer vents should be cleaned annually to prevent fire risk.
In most Norwalk homes, routine air duct cleaning counts as upkeep that insurance will not reimburse, yet HVAC mold remediation that follows a covered water loss like a burst pipe or flood is usually covered. When the contamination in your ductwork stems from a covered event, Green Restoration documents the work under IICRC S520 and bills your carrier directly. For standard maintenance cleanings outside that scenario, financing is available.
For Norwalk ductwork, we rely on NADCA ACR-standard source-removal gear, running rotary brushes through each duct branch while a HEPA-filtered negative-air collector pulls debris at the main trunk. The budget alternative, compressed-air-only cleaning known as air-whip or air-sweep, tends to leave debris behind. Source removal under NADCA is the only approach that reliably clears post-cleaning verification.
