What Is NADCA ACR-2021 Air Duct Cleaning?
Air duct cleaning is the NADCA ACR-2021 documented process of returning an HVAC system to a verified level of cleanliness through source removal, holding the system under continuous negative pressure while rotary brushes, air whips, and contact vacuuming dislodge debris into HEPA-filtered collection equipment instead of pushing it through the building. The standard treats the entire system as the unit of work: supply and return ducts, registers, plenum, evaporator coil, drain pan, blower, and air handler housing, because a component left dirty recontaminates everything already cleaned.
In Old Lyme, CT, the visit runs in sequence: camera inspection of the supply and return runs, service access cut where the trunk has none, HEPA-filtered negative air connected at the main trunk, then branch-by-branch agitation worked back toward the collection unit. The air handler is opened last, and the evaporator coil, drain pan, and blower wheel are cleaned by hand. The dryer exhaust is a separate duct with its own lint load and its own fire risk, so it is cleaned and quoted separately.

Why Old Lyme Systems Are Cleaned Differently
Duct cleaning carries no state license in Connecticut, New York, or Massachusetts, so the building and the method decide the job. Connecticut suburban stock built between the 1950s and the 1970s has the opposite problem: generous galvanized trunks in the basement, long branch runs out to bedroom registers, and a coil that has been in service far longer than the duct around it. Panned joist-bay returns are common in that era and cannot be cleaned without cutting proper access.
Green Restoration works to the ACR-2021 source-removal standard on every system, cleans the coil, drain pan, and blower as part of the job rather than as an add-on, and inspects each run on camera. ASHRAE 62.2 sets ventilation rates for dwellings and 62.1 for commercial buildings; neither is a cleaning standard, which is why ACR-2021 governs the work itself.

Before And After Verification
Inspection camera footage inside every duct branch and the air handler, delivered as a digital file for your records.
EPA Antimicrobial Coil Treatment
Every cleaning closes with EPA-registered antimicrobial on the evaporator coil, critical in Old Lyme's coastal humidity.
What Dirty Ductwork Costs Your Old Lyme Home
Most Old Lyme 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 shoreline and Connecticut River valley homes make buildup compound fast.
Dust, Dander And Pollen Buildup
Recirculating Through Every Room
The average Old Lyme 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
Old Lyme's 1800s Lyme Art Colony homes on Lyme Street and shore cottages at Sound View and Old Lyme Shores see seasonal rodent intrusion into attic ductwork. Droppings dry, pulverize in the airflow, and reach every bedroom through supply registers.
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 Old Lyme Homes Need Professional Air Duct Cleaning
Old Lyme'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 Old Lyme 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 Old Lyme 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 Old Lyme homes where Long Island Sound humidity condenses on coils and mold returns within weeks without treatment.
Before-And-After Verification Photos
Every Old Lyme 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 Old Lyme
You've seen the ads. “Whole-house air duct cleaning, $69!” Those offers are bait-and-switch operations, and the number on the ad is not the number on the invoice. 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.0668405
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 Old Lyme homeowner is quoted $69 to $199 for whole-house cleaning, call (833) 833-3637 for an honest, itemized estimate instead.
What We Find In Old Lyme Air Ducts
Old Lyme runs from Lyme Art Colony homes on Lyme Street to shore cottages at Sound View and Old Lyme Shores, 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 Old Lyme, older Lyme Street homes 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 Old Lyme, CT.
Air duct cleaning in Old Lyme 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 Old Lyme HVAC cleaning takes 3 to 4 hours. Multi-zone systems or long-run ductwork in larger Sound View or Lyme Street homes 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 Old Lyme 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.
For most Old Lyme homeowners, routine air duct cleaning counts as upkeep that insurance does not pay for, yet HVAC mold remediation after a covered water loss like a burst pipe or flood is usually covered. When duct contamination traces back to a covered event, Green Restoration bills the carrier directly with IICRC S520 documentation; for scheduled maintenance cleanings instead, we provide financing options.
Our Old Lyme crews rely on NADCA ACR-standard source-removal equipment, running rotary brushes through every duct branch alongside HEPA-filtered negative-air collection at the main trunk. The cheaper compressed-air-only approach, sometimes called air-whip or air-sweep, leaves debris in place, which is why NADCA source-removal remains the one method that reliably passes post-cleaning verification.
Yes, professional duct cleaning reduces airborne particulates, dust mites, pet dander, pollen, and mold spores that recirculate through HVAC systems in Old Lyme homes. The EPA and ASHRAE both recognize HVAC cleaning as part of overall indoor air quality improvement, especially when paired with quality filtration (MERV 13+) and source control for the underlying contamination.
Full dryer vent cleaning includes lint removal from the dryer drum housing, the flex duct between dryer and wall, the full rigid duct run through the home or crawlspace, and the exterior vent cap. Rooftop and long-run vents common in Old Lyme Colonials require specialized rotary rod systems we carry on every truck. Standalone dryer vent cleaning starts at $249 and takes under an hour. Bundle it with HVAC duct cleaning to get the dryer vent service free.
Green Restoration follows NADCA ACR-2021 source-removal standard, locally operated, and equipped for the HVAC challenges Old Lyme properties face, from 1800s Lyme Art Colony homes on Lyme Street and shore cottages on Sound View to multi-zone systems in larger homes near Sound View and the Old Lyme Shores shoreline. We use HEPA-filtered collection, rotary brush agitation, and EPA-registered coil treatment on every job. Our before-and-after verification photos, direct billing, and 24/7 scheduling at (833) 833-3637 mean your air is cleaner and documented with one call.
