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 Washington homes.
HVAC Mold Remediation
Mold living inside ductwork, coils, and air handlers is remediated under IICRC S520-2024 with negative-air containment, EPA-registered antimicrobial treatment, and independent third-party clearance verification.
HEPA Filtration And Negative-Air
Captured at the source, hospital-grade HEPA H13 filtration with negative-air containment removes 99.97% of particles at 0.3 microns, the prerequisite for cleaning that satisfies the NADCA ACR-2021 standard.
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 Washington attics and crawl spaces.
Commercial HVAC Cleaning
Commercial-grade duct cleaning for office buildings, restaurants, medical facilities, and retail spaces in Washington, with after-hours scheduling and full ASHRAE 62.1 compliance documentation.
Indoor Air Quality Testing
Testing of indoor air quality before and after cleaning applies lab-analyzed particle counts, VOC screening, and ASTM D7338 mold spore sampling to verify the HVAC cleaning improved breathing air.
UV Light And Sanitization Install
Professional installation of in-duct UV-C light systems and electrostatic filtration upgrades prevents microbial regrowth on coils and inside handlers across the Washington ridgeline between cleaning cycles.
Aeroseal Duct Sealing And Leak Reduction
From inside the existing duct system, Aeroseal aerosolized polymer sealant seals the joints, seams, and the pinholes, reducing conditioned air loss up to 40% per ANSI/UL 181 sealant listings.

Why Choose Us In Washington
NADCA ACR source-removal cleaning, HEPA-filtered collection, EPA-registered coil treatment, and on-camera before-and-after verification on every Washington air duct job.
NADCA ACR Source-Removal
Every supply and return duct scrubbed under negative pressure with rotary brushes, never compressed-air-only shortcuts.
HEPA-Filtered Negative Air
Truck-mounted HEPA collection captures 99.97% of loosened debris at the main trunk instead of blowing it into your home.
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 Washington's Lake Waramaug summer humidity.
What Dirty Ductwork Costs Your Washington Home
Most Washington homeowners don't think about their ductwork until allergies flare, heating oil bills climb, or a musty smell starts blowing out of the vents. Lake Waramaug humidity, original galvanized trunks in estate stock, and long supply runs in Litchfield Hills homes make buildup compound fast.
Lake Waramaug Humidity Loading Coils
Pulling Moisture Through HVAC All Summer
Estate homes on Lake Waramaug, New Preston, and Wykeham Road sit on a lake the size of 656 acres. Summer lake humidity gets pulled through fresh-air intakes, condenses on cold evaporator coils, and seeds mold colonies on coil fins and inside supply plenums.
Old Estate Stock Has Original Duct Runs
Decades Of Settled Debris In Galvanized Trunks
Estate homes on the Washington Green and along Nettleton Hollow and Calhoun Corners often run on original galvanized duct retrofitted in the 1950s and 1960s. Decades of construction dust, pet hair, and renovation debris coat the bottom of every trunk and never get reached by surface-blow cleaning.
Reduced HVAC Efficiency
Higher Heating Oil And Propane Bills
Most Washington homes still burn oil or propane through the long Litchfield Hills winter. A clogged duct system forces the air handler to work harder, driving fuel and electric bills up 15 to 25% and cutting equipment life in half. Clean ducts pay back inside two billing cycles.
Rodent And Insect Contamination
Field Mice In Attic And Outbuilding Ductwork
Estates around Marbledale, Romford, and Bee Brook back up to working farms, woodland, and conservation land. Field mice push into attic flex duct and barn-conversion supply boots every fall. Droppings dry, pulverize in the airflow, and reach every bedroom through the supply trunk.
Post-Construction Debris
Drywall Dust, Sawdust, Joint Compound
Renovations on historic Washington Depot homes and Lake Waramaug estate restorations push joint compound, plaster dust, and sawdust into the supply trunk. Without a NADCA ACR-2021 post-construction reset that debris blows back out of every register for months after the contractor leaves.
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. Long flex-duct runs through estate basements and detached carriage houses are common in Washington. A full vent cleaning to the exterior cap takes under an hour and eliminates the risk.

Why Washington Homes Need Professional Air Duct Cleaning
Washington's Lake Waramaug summer humidity, older HVAC retrofits in estate stock around the Washington Green and New Preston, and long supply runs in Litchfield Hills properties 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 Litchfield County crews follow the National Air Duct Cleaners Association ACR standard for source-removal, not surface-blow. Every duct branch in a Lake Waramaug or Washington Green estate is scrubbed under negative pressure with rotary brushes and HEPA vacuum collection, not blown out with a leaf blower.
Full HVAC System Coverage, Not Just Registers
Most Washington 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 estate HVAC system is decontaminated, not just the first six inches of register grille.
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 Washington estates near Lake Waramaug where summer lake humidity condenses water on cold coils and mold returns within weeks without treatment.
Before-And-After Verification Photos
Every Washington 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 on a New Preston or Lake Waramaug property.
Why We Don't Offer $69 Air Duct Cleaning In Washington
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 AMRT + WRT certified, 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 Washington homeowner is quoted $69 to $199 for whole-house cleaning, call (860) 222-9498 for an honest, itemized estimate instead.
What We Find In Washington Air Ducts
Washington runs from historic Litchfield Hills Colonials to country homes near Lake Waramaug, and that lake-country humidity drives real duct buildup, so every job here is done to the NADCA ACR-2021 source-removal standard with before and after photos.

Dryer Vent, Lint Cleared
In Washington, older Colonials here often run long dryer lines that pack with lint out of sight.
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 Washington, CT.
Air duct cleaning in Washington 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 Washington HVAC cleaning takes 3 to 4 hours. Multi-zone systems or long-run ductwork in estates on Lake Waramaug, multi-zone properties on the Washington Green, or large homes along Nettleton Hollow can take 6 to 8 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 Washington homes, with more frequent cleaning for households with pets, allergy sufferers, wood-stove use, or recent construction. Estates near Lake Waramaug often benefit from 3-year cycles because lake-effect summer humidity accelerates coil and duct contamination. Dryer vents should be cleaned annually to prevent fire risk.
For Washington homeowners, routine air duct cleaning usually counts as upkeep that insurance will not cover, yet HVAC mold remediation that follows a covered water loss like a burst pipe or flood is normally covered. Whenever ductwork contamination traces back to a covered event, Green Restoration bills the carrier directly and supplies IICRC S520 documentation. When the work is a scheduled maintenance cleaning instead, we make financing available.
In Washington we rely on NADCA ACR-standard source-removal equipment, running rotary brushes through every duct branch and pairing that with HEPA-filtered negative-air collection at the main trunk. The cheaper compressed-air-only approach, sometimes called air-whip or air-sweep, tends to leave debris in place. Source removal under NADCA is the one method that reliably passes post-cleaning verification.
