Why CleanRun Air Duct Cleaning Leesburg Is Chantilly’s Preferred Air Duct Cleaning Company
We’ve been working Chantilly homes since 2013, and the pattern is unmistakable: the Dulles Tech Corridor subdivisions built between 1982 and 2005 are hitting a simultaneous end-of-useful-life moment for their fiberglass duct board and flex-duct systems. Our customers here don’t need a sales pitch. They need someone who recognizes delaminating duct board when the camera shows it, and who documents the finding in writing before proposing a fix.
Our Air Duct Cleaning team arrives in marked vehicles, uniformed and background-checked under Haven Standard Clause 3: Verified Crews. Tomas Reyes built CleanRun on a single rule - every job gets a written price before work starts, and every duct run gets photographed before and after. No exceptions. That rule has carried through 52,000+ homes, including thousands in Fairfax and Loudoun counties.
The 365-Day Done Right Promise backs every Chantilly job in writing. If the work isn’t right, we make it right. Not a policy buried in fine print. A written guarantee.
Our Air Duct Cleaning Services in Chantilly

Residential Duct Cleaning
Chantilly’s housing stock is almost entirely two-story colonials and townhomes from the 1982-2005 build-out, with fiberglass duct board trunks and flex-duct branches run through attic chases. At 20-40 years old, that duct board is prone to surface delamination - the liner sheds particles into your air stream even when the surface looks merely dusty. Our residential cleans begin with a video inspection of every trunk and branch, so we know whether we’re looking at intact ductwork that needs source removal, or deteriorating liner that needs encapsulation or section replacement. We use Rotobrush and Nikro equipment for negative-pressure extraction, HEPA-filtered to capture rather than redistribute.

Commercial Duct Cleaning
The Route 28 corridor and Dulles Airport surroundings remain among Northern Virginia’s most active commercial development zones, and that construction activity loads HVAC systems in nearby offices, retail, and mixed-use buildings with particulate that standard filter changes don’t catch. We clean commercial systems in Chantilly’s office parks and retail strips with the same documentation standard as our residential work: written scope, written price, photographed before-and-after on every duct run. Equipment includes Abatement Technologies negative-air machines sized to the system CFM.

Supply Duct Cleaning
Supply runs deliver conditioned air to your registers, but in Chantilly’s older subdivisions they’re often flex-duct branches that have been crushed by storage items in attic chases, or disconnected entirely at the collar. We don’t just vacuum the accessible end. Our video inspection traces each branch from the plenum to the boot, identifying airflow restrictions that cleaning alone won’t fix. When we find a crushed run above the master bath - a common failure in Chantilly Highlands homes with low-clearance attic access - we document it, quote the repair in writing, and seal the connection properly so air reaches the room, not the attic.

Return Duct Cleaning
Return ducts pull air back to the air handler, and in Chantilly homes near active construction along Route 28 or the Dulles Toll Road, that return air carries more than household dust. We’ve opened return plenums packed with drywall gypsum and concrete fines from years of nearby commercial development - material that bypasses standard filters and embeds in the ductwork. Our return-side cleaning includes plenum access, filter housing inspection, and sealing of any leaks that draw unfiltered attic or wall-cavity air. HEPA-filtered negative pressure captures the debris rather than pushing it through the system.

Full System Cleaning
A full system clean addresses supply trunk, return trunk, all branch runs, plenums, and the air handler cabinet. In Chantilly’s 1982-2005 homes, this is almost always the right scope because contamination isn’t isolated to one section. The long HVAC season here - cooling May through October, heating November through March - means near-continuous operation that distributes debris throughout. We quote full system cleans as a flat price per system, not per vent, with the written scope itemized before we start.

Video Inspection
Every Chantilly job starts here. We run a camera through the trunk and key branches to show you what’s inside before we propose any work. The video reveals delaminating duct board, crushed flex runs, disconnected collars, and microbial growth that a flashlight and mirror miss. You see what we see. The footage becomes part of your documented job record, delivered with the before-and-after photos.

Our equipment roster includes Rotobrush brush-and-vac systems, Nikro HEPA-filtered negative air machines, and Honeywell and Aprilaire media filters and electronic air cleaners that we install when existing filtration is inadequate for Chantilly’s construction-dust load. We don’t claim performance beyond manufacturer specifications. We do name the brands so you can verify what we’re using before you agree to a price. Parts for common Chantilly systems are stocked locally, so when a video inspection finds a repair need, turnaround doesn’t depend on a warehouse in another state.
Common Air Duct Cleaning Problems We See in Chantilly Homes

- Fiberglass duct board delamination in 1982-2005 builds. The surface looks dirty but intact until the agitation brush lifts the liner. Delaminated duct board sheds particles continuously; vacuuming the surface without addressing the substrate means the problem returns within months. We flag it on camera and quote encapsulation or section replacement in writing.
- Crushed or disconnected flex branch runs in attic chases. Chantilly’s low-clearance attics make it hard to see the full branch length. The master bath register blows weakly while the attic gets conditioned air. Our video inspection finds these without cutting drywall.
- Return plenums loaded with construction particulate near Route 28 and Dulles development zones. Drywall gypsum and concrete fines bypass standard filters and embed in the return trunk. Cleaning the supply side only leaves the contamination source intact. We clean and seal the return plenum so the system draws from the house, not the attic or wall cavities.
- Moisture cycling and microbial growth in uninsulated attic flex duct. Northern Virginia’s humid summers push attic temperatures to 130°F while interiors stay at 72°F. Condensation forms on poorly sealed flex duct, promoting mold inside the section. We find it with the camera and recommend sealing or replacement depending on severity.

FAQs - Air Duct Cleaning in Chantilly

Because the 1982-2005 subdivisions that define Chantilly used fiberglass duct board trunks that are now delaminating in place. The camera shows intact surface until the agitation brush lifts the liner, and once that happens, vacuuming alone isn’t enough. We quote encapsulation or section replacement in writing before proceeding, so you decide with full information. Call (571) 487-7204 for an exact scope and price.
Yes. The active commercial development along Route 28 and the Dulles Toll Road corridor generates drywall dust, concrete fines, and other construction particulate that your return system pulls in, especially if the plenum or filter housing has leaks. We’ve opened returns in Chantilly Highlands homes packed with gypsum that standard filters never designed to catch. We clean the return trunk and seal the plenum so the system draws conditioned house air, not construction zone air.
Significantly. Attic temperatures in Chantilly hit 130°F in July while your interior stays at 72°F. That temperature differential causes condensation on uninsulated or poorly sealed flex duct runs, and the humidity - Northern Virginia’s subtropical summer pushes indoor relative humidity into the 60-70% range - creates moisture cycling that promotes mold growth inside duct sections. We find it with video inspection and address it through sealing or replacement, not just surface cleaning.
Source removal of contaminants from the entire HVAC system, including supply and return trunks, branch runs, registers, grilles, diffusers, plenums, and the air handler cabinet. On a typical Chantilly two-story colonial with 12-16 runs, that means negative-pressure extraction with HEPA filtration, mechanical agitation to dislodge debris, and protected access so no contamination escapes into the living space. We add our own standard: video inspection before, photographed documentation after, and a written scope that itemizes what was done. The NADCA standard is the floor. Our documented photo record is the verification.
In most cases, yes. We run a video camera through the trunk and accessible branch lines to locate crushed flex duct, disconnected collars, and collapsed sections. Chantilly’s attic chases are tight but usually accessible enough to trace branches from the plenum to the boot. When we find a problem, we show you the footage, quote the repair in writing, and access through the attic or crawlspace rather than cutting interior drywall. Call (571) 487-7204 to schedule the inspection.
