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 McLean
McLean homeowners call CleanRun at (240) 771-1508 when they need Air Duct Cleaning that comes with a written price before work starts and a documented photo record when the crew leaves. We’re familiar with the oversized multi-zone systems in estates off Old Dominion Drive, the layered renovations near Chain Bridge Road, and the original 1970s ductwork still hiding in attics above gleaming new kitchens. Dispatch and scheduling are coordinated from our Washington, DC office, but our crews serve McLean locally every day of the week.
Why CleanRun Air Duct Cleaning Ashburn Is McLean’s Preferred Air Duct Cleaning Company
CleanRun has been independently owned and operated under the Haven Standard since 2013. In that time we’ve served more than 52,000 homes, every one with a written price agreed before a single panel came off and a photo record delivered at the end of the job. McLean customers specifically choose us because we understand what their homes actually contain: not standard suburban ductwork, but complex networks of aging flexible liner, original fiberglass duct board, and three or more air handlers spread across 5,000-10,000 square feet.
Our technicians are background-checked, uniformed, and identified by name before arrival - Haven Standard Clause 3: Verified Crews. We don’t send a different subcontractor to every job. The crew that quotes your McLean home is the crew that performs the work, documents it, and stands behind it.
Every job is backed by our 365-Day Done Right Promise, written on the invoice, not buried in a policy manual. If the work isn’t right, we make it right. No manager approval required. And we publish our license number on every page because credentials should be verifiable, not implied.
Our Air Duct Cleaning Services in McLean
Residential Duct Cleaning
McLean’s housing stock demands more than a shop-vac at the register. A typical estate home in the 22101 or 22102 zip codes has hundreds of linear feet of ductwork running through unconditioned attic and crawl-space zones, often original to a 1960s-70s core that was later wrapped in additions. Our residential service starts with a video inspection of the full system, then source removal under negative pressure - that means we seal the duct network and use suction to pull debris out rather than blowing it deeper in. We document every run before and after, and the homeowner receives the photo record as a standard deliverable.
Commercial Duct Cleaning
McLean’s commercial base includes lobbying firms, consulting offices, and medical practices along Dolley Madison Boulevard and near the Tysons corridor. These spaces typically share a building with residential tenants or operate in converted single-family structures, which means commercial-grade HVAC expectations loaded onto residential-scale ductwork. We clean and document these hybrid systems with the same Rotobrush and Nikro equipment we use on large homes, and we schedule around business hours to avoid disrupting client-facing operations.
Supply Duct Cleaning
Supply ducts push conditioned air into your rooms. In McLean, we frequently find these runs compromised by kinked flexible liner, especially in homes where subsequent renovations rerouted walls but left the original duct path intact. A kinked supply run doesn’t just reduce airflow - it creates a pressure drop that pulls unconditioned attic air into the system through leaks elsewhere. Our supply duct service includes reconnection of disconnected runs and sealing with Guardsman mastic where the original attachment has failed. This is the difference between cleaning the ducts and fixing the system.
Return Duct Cleaning
Return ducts pull air back to the air handler for reconditioning. In McLean’s larger homes, these runs are often oversized galvanized trunk lines from the original construction, now coated with decades of accumulation and in some cases partially collapsed where renovation crews walked across them in attics. Return duct cleaning requires higher suction capacity because the debris layer is typically thicker and more compacted. We use Abatement Technologies negative-pressure equipment sized for the job, and we photograph the trunk interior at multiple access points so you can see what was actually removed.
Full System Cleaning
This is our most called-for service in McLean, and for good reason. A full system cleaning addresses every component: supply runs, return runs, trunk lines, plenums, registers, and the air handler cabinet itself. Most McLean homes need this level of work because surface cleaning of accessible registers leaves the majority of the debris - and the majority of the problems - untouched in attic and crawl-space runs. The full system service includes our video inspection, source removal with HEPA filtration, and the documented photo record of every duct run. If we find disconnected or damaged runs during the inspection, we’ll note them in writing and quote reconnection or sealing before any additional work proceeds.
Video Inspection
Every McLean job starts here. We run a camera through the duct network and show you what we find before quoting a dollar figure. In a recent job near Swinks Mill Road, the camera revealed a 3-inch debris build-up at the first elbow of a return trunk, plus a disconnected flexible run that had been blowing conditioned air into the attic for an estimated decade. The homeowner had no idea. Video inspection removes guesswork from pricing and gives you a baseline for measuring results.

BeforeAfterTrusted Brands We Service in McLean
CleanRun crews arrive with professional-grade equipment from trade-recognized manufacturers: Rotobrush agitation tools, Nikro and Abatement Technologies negative-pressure systems, and Honeywell and Aprilaire media filters for replacement where the existing filter rack has degraded. We stock Guardsman mastic and sealing products specifically for the fiberglass duct board and flexible liner repairs common in McLean’s older homes. These aren’t proprietary tools with made-up performance claims - they’re brands any homeowner can look up independently, and we name them because accountability starts with transparency about what touches your system.
Common Air Duct Cleaning Problems We See in McLean Homes
- Original fiberglass duct board shedding fibers into supply air. McLean homes that received full kitchen and bath renovations in the 2000s-2010s frequently still have their original 1970s fiberglass duct board intact in attic runs. Homeowners assume “renovation” meant everything was updated, but the ductwork was never touched, and the deteriorating liner is now shedding glass fibers directly into supply air. The camera shows this clearly; the photo record proves it was addressed.
- Disconnected or kinked flexible runs in multi-zone systems. Large estate homes routinely have three or more air handlers and dozens of flexible duct runs. Our tech was running camera inspection on a multi-zone system in a 7,200 sq ft home off Old Dominion Drive when we found three disconnected flexible runs and a kinked liner feeding the primary suite; the 1980s duct board plenum was shedding glass fibers into supply air. After source removal under negative pressure with HEPA filtration and Rotobrush agitation tools, we reconnected the runs, sealed the plenum with Guardsman mastic, and the homeowner finally stopped seeing fiberglass dust at the registers.
- Mold colonization accelerated by Potomac valley humidity. McLean sits in the Potomac River valley, giving it consistently higher ambient relative humidity than inland Northern Virginia suburbs even a few miles west. This sustained moisture load accelerates mold colonization on duct liner surfaces and insulation, making biannual cleaning a more defensible recommendation here than in drier DC-area markets. Routine cleaning without addressing the moisture source lets mold return within a single cooling season.
- Original galvanized or fiberglass plenums layered beneath new construction. McLean’s teardown-and-rebuild cycle means many properties layer new construction additions onto older 1960s-70s cores, leaving behind original galvanized or fiberglass duct-board plenums that were never replaced during otherwise extensive cosmetic renovations. These plenums corrode, delaminate, and leak, creating pressure imbalances that reduce system efficiency and pull unfiltered attic air into the living space.
Pricing for Air Duct Cleaning in McLean, VA
A typical residential duct cleaning in McLean runs $480-$780 for a standard 2,500-4,000 sq ft home with a single air handler and accessible ductwork. Full system cleaning for the 5,000-10,000 sq ft estates common in the 22101 zip code, with three or more air handlers and hundreds of linear feet of duct runs, typically ranges $1,200-$2,400. Video inspection alone is $180-$280, credited toward the cleaning price if you proceed. Duct repair and sealing, including reconnection of disconnected runs and plenum sealing with Guardsman mastic, adds $340-$680 depending on accessibility and extent.
What moves the price: number of air handlers, linear feet of ductwork, accessibility of attic and crawl-space runs, and whether we find damage requiring repair beyond standard cleaning. We deliver a written price before any work starts - Haven Standard Clause 1 - and that price does not change unless you authorize additional scope in writing. No per-vent pricing. No coupon that doubles once the truck is in your driveway. Call (240) 771-1508 for a free estimate; we’ll inspect, document, and quote in the same visit.

FAQs - Air Duct Cleaning in McLean
Yes, very likely. In McLean, full kitchen and bath remodels from the 2000s-2010s frequently left the original 1970s fiberglass duct board untouched in attic runs, so even “fully renovated” homes still blow shedding glass fibers from the same liner that served the original build. The renovation contract probably didn’t mention ductwork because it wasn’t visible. Our video inspection will show you exactly what remains in your system. Call (240) 771-1508 for a free estimate - estimates include the camera walkthrough.
McLean’s combination of oversized duct networks, 25-40 year old liner, and consistently higher humidity from the Potomac River valley creates accumulation and mold colonization at rates that simply don’t apply to smaller, newer subdivisions in neighboring cities like Vienna or Reston. The same climate that makes McLean’s oak canopy lush also keeps duct liner surfaces damp enough to support microbial growth through extended cooling seasons. Biannual inspection, with cleaning as indicated by the photo record, is a defensible maintenance interval here. Your Reston friends’ system is probably half the size and half the age.
We treat each zone as a separate subsystem with its own inspection, documentation, and cleaning protocol. A 7,000 sq ft home with three air handlers typically requires a full day of work, two technicians, and separate photo records for each zone’s supply and return runs. We quote these jobs as single-scope projects with one flat price, not per-zone add-ons. The written scope specifies which air handlers, which trunk lines, and which access points are included. Haven Standard Clause 1: no work starts until the full price is in writing.
Cleaning removes loose debris, but fiberglass dust at registers usually indicates deteriorating duct board or damaged flexible liner that is actively shedding material. In that case, cleaning alone won’t stop the dust - the source needs sealing or replacement. During our video inspection, we identify whether you’re seeing accumulated debris or active liner degradation. If it’s the latter, we’ll quote sealing with Guardsman mastic or targeted liner replacement before cleaning, so you’re not paying to clean ducts that will recontaminate immediately. The photo record shows you which scenario applies to your home.
A standard cleaning typically addresses accessible supply registers and the immediate duct runs behind them. Our full system cleaning - the service we recommend for most McLean homes - includes every supply run, every return run, all trunk lines, both plenums, the air handler cabinet, and the registers themselves, with video inspection before and photo documentation after. Given McLean’s complex multi-zone systems and the frequency of disconnected or damaged runs found during inspection, the full system approach is the only way to ensure the problem you called about is the problem we actually fixed. Written scope, written price, written guarantee.
