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
Air duct cleaning in McLean typically runs $450-$1,200 per HVAC system depending on system count, duct accessibility, and whether video inspection is included. Most McLean homes need two to three systems cleaned, and we quote every job with a written price before work starts under Haven Standard Clause 1. Call (240) 255-4519 for a free estimate.
We serve McLean from our Washington, DC scheduling office, with crews running daily routes through the 22101 and 22102 corridors. Our technicians know the difference between a 1962 split-level off Dolley Madison Boulevard and a 1987 colonial on Swinks Mill Road, and they carry the right equipment for both. That matters because McLean’s housing stock isn’t uniform, and duct systems that have been modified through multiple renovations don’t respond to one-size-fits-all cleaning.
Why CleanRun Air Duct Cleaning Rockville Is McLean’s Preferred Air Duct Cleaning Company
We’ve worked in McLean since 2013, and the pattern is consistent: homes here are larger, older, and more complex than their square footage suggests. A 5,000 sq ft colonial off Old Dominion Drive might have started as a 2,800 sq ft ranch in 1968, gained a second story in 1985, a finished basement in 1999, and a third-floor bump-out in 2012. Each addition brought new duct runs, new zones, and new opportunities for debris to accumulate where no prior crew looked. Our Air Duct Cleaning in McLean customers come back because we document what we find, photograph what we clean, and price by the system so nothing gets skipped for the sake of a low headline number.
Our local reputation is built on evidence, not claims. Every job includes a Documented Photo Record of every duct run, delivered to the customer before we leave. The 365-Day Done Right Promise is written on every invoice, not buried in a website footer. Technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews, and they’re identified by name before arrival. We don’t do urgency theatre or limited-time offers. We do written prices, photographed results, and accountability.
Our Air Duct Cleaning Services in McLean
Residential Duct Cleaning
McLean’s residential market is dominated by 4,000-7,000+ sq ft homes on wooded lots, many with two or three independently zoned systems. A single-system quote doesn’t fit here. We price by the HVAC system, not by the vent count, because a three-zone colonial with dead-leg runs from a 1990s basement finish requires fundamentally different work than a one-system rancher. Our residential jobs include negative-pressure extraction - pulling debris out under controlled vacuum so it doesn’t re-enter your living space - and every run is photographed before and after.
Commercial Duct Cleaning
McLean’s commercial base includes professional offices along Chain Bridge Road, medical suites near Tysons, and retail spaces in mixed-use developments. These systems see higher occupancy cycling and different contaminant profiles than residential work. We quote commercial jobs with the same written-price protocol, and we coordinate around business hours to minimize disruption. Equipment includes Abatement Technologies HEPA-filtered negative air machines and Rotobrush agitation tools sized for larger trunk diameters.
Supply Duct Cleaning
Supply ducts push conditioned air into your rooms, and in McLean homes they’re often the original galvanized trunk lines from the 1960s or 70s, extended with flex duct into later additions. The transition points trap debris. We use mechanical agitation to loosen buildup at elbows and reducers, then extract under negative pressure. Camera verification confirms the trunk is clear before we move to the next zone.
Return Duct Cleaning
Return ducts pull air back to the air handler, and in pre-1990 McLean homes they’re frequently the weak point. Older return-air grilles are loosely fitted, and without proper containment, dislodged dust simply recirculates. Our return duct cleaning includes sealed negative-pressure containment at the grille and camera inspection at the air handler plenum - the central distribution box - to verify debris was actually removed, not just moved around. This is where most coupon-cleaning jobs fail, and it’s why we document every return path.
Full System Cleaning
For McLean homes with multiple zones and renovation history, we recommend full system cleaning: supply and return paths for every HVAC system, plus the air handler cabinet, blower assembly, and plenum connections. This is the only way to address cross-contamination between zones. We quote full system work as a per-system price, with a written scope that names every duct run to be cleaned and photographed.
Video Inspection
Our video inspection service uses a borescope camera to show you the inside of your ductwork before you commit to cleaning. In McLean, this is particularly valuable for homes with dead-leg runs from basement or third-floor additions - the camera reveals whether there’s 40 years of compacted debris or just light dust, so your decision is based on what we can see, not what we claim. Video inspection is included as standard on every full system cleaning, and available as a standalone service for $180-$240.

AfterTrusted Brands We Service in McLean
CleanRun technicians service and clean ductwork connected to all major HVAC brands, and we stock components from Honeywell, Aprilaire, and Guardsman for common McLean system configurations - particularly the multi-zone setups with Honeywell zone panels and Aprilaire media air cleaners found in many local homes. We don’t sell equipment we can’t support, and we don’t make performance claims beyond manufacturer specifications. If your system uses Abatement Technologies filtration or Guardsman UV sanitizing accessories, we carry those components too. Parts availability means faster turnaround when a cleaning reveals a repair need, and it means we can quote that repair in writing while we’re still on site.
Common Air Duct Cleaning Problems We See in McLean Homes
- Dead-leg runs from successive additions. In the neighborhoods along Old Dominion Drive and Chain Bridge Road, 1960s-70s homes commonly have duct systems where the original stamped-metal trunk was extended with flex duct into a subsequently finished basement or added third floor. These near-inaccessible runs reliably contain 40-plus years of compacted debris, and crews that quote one flat fee often skip them entirely.
- Loose return-air grilles allowing pollen infiltration. McLean’s exceptional tree cover of oak, tulip poplar, and maple produces some of the highest airborne pollen loads in the mid-Atlantic. Older, loosely fitted return-air grilles typical of pre-1990 construction pull that pollen directly into the duct system, where it accumulates on trunk walls and blower components.
- Moisture-trapping flex duct in unconditioned spaces. Crawl spaces and large unconditioned attics are common in McLean homes, providing long stretches of insulated flex duct. Summer dew points regularly exceeding 70°F, combined with long HVAC runtimes, create conditions for microbial growth inside these runs - growth that agitation alone won’t address without camera verification.
- Cross-contamination between renovated zones. When a basement finish or third-floor addition ties into an existing trunk without proper isolation, debris from the new construction zone migrates into the original ductwork. We’ve found construction particulate - drywall dust, insulation fragments, sawdust - in supply runs 15 years after the renovation was completed.
Pricing for Air Duct Cleaning in McLean, VA
Because most McLean homes are 4,000-7,000+ sq ft with two or more independently zoned systems and duct runs that have been extended through multiple additions, per-system pricing is the only honest way to quote duct cleaning here. A single lump-sum price either overcharges a one-system rancher or underfunds a three-system colonial with 40-year-old dead-leg runs.
| Service | Typical Range in McLean |
|---|---|
| Single-system residential cleaning | $450-$680 |
| Each additional HVAC system | $320-$520 |
| Full system cleaning (supply + return + air handler) | $680-$1,200 per system |
| Standalone video inspection | $180-$240 |
| Air handler / blower cabinet cleaning | $140-$220 (when added to duct cleaning) |
What moves a McLean job toward the higher end: three or more systems, dead-leg runs requiring access through finished ceilings or crawl spaces, visible microbial growth in flex duct, or construction debris from recent renovation. What keeps it toward the lower end: single-zone systems with accessible registers and straight trunk lines. Every quote is written and agreed before work starts - no per-vent add-ons, no equipment charges that appear after the crew arrives. Call (240) 255-4519 for an exact quote; estimates are free.

FAQs - Air Duct Cleaning in McLean
We price by the system, not by the house. A three-system colonial in McLean typically runs $1,090-$1,720 for full cleaning of all supply and return paths, with each additional system adding $320-$520 to the base single-system price. This ensures the crew has time to reach every duct run, including the dead-leg extensions from basement and third-floor additions that single-price competitors routinely skip. Call (240) 255-4519 for a written quote that names every system and every run to be cleaned.
The most common cause is a dead-leg duct run from an addition that was tied into the original trunk without proper sizing or balancing. In McLean’s 1960s-80s stock, basement finishes and bump-out additions frequently use undersized flex duct with excessive elbows, creating restriction points that also trap debris. Our video inspection identifies these runs, and our cleaning protocol includes mechanical agitation and negative-pressure extraction to restore design airflow. If the duct is physically undersized, we’ll document that in the photo record so you have evidence for a future modification decision.
Yes. Our work conforms to NADCA ACR, the Assessment, Cleaning, and Restoration standard for HVAC systems. For McLean homes, this means source removal - physically dislodging and extracting debris rather than applying chemical treatments that mask the problem - and containment of the work area to prevent cross-contamination. The Haven Standard adds requirements NADCA doesn’t mandate: written pricing before work starts, photo documentation of every run, and the 365-Day Done Right Promise backed in writing on every job.
McLean’s dense deciduous canopy produces pollen loads that infiltrate through older return grilles and accumulate in duct systems, particularly in pre-1990 homes with loose-fitting register seals. Most McLean homes benefit from cleaning every 4-6 years, sooner if you’ve completed renovation work or notice increased allergy symptoms during peak pollen season. Homes with Aprilaire or Honeywell media air cleaners may extend that interval if filters are changed on schedule. We can assess your specific load during a video inspection and recommend an interval based on what the camera shows, not a calendar.
You receive three deliverables: a written invoice with the agreed scope and final price, a Documented Photo Record showing the inside of every duct run before and after cleaning, and the 365-Day Done Right Promise in writing. For McLean’s multi-system homes, the photo record is organized by zone - first floor, second floor, basement, third floor - so you can verify that dead-leg runs from additions were actually reached. If a run couldn’t be accessed, it’s noted in writing with the reason, not omitted. This documentation is your evidence that the work happened; without it, you’re trusting a van invoice.
We were called to a 1970s colonial off Old Dominion Drive where a finished basement and a third-floor bump-out had each been tied into the original stamped-metal trunk with flex duct, leaving two dead-leg runs no one had ever touched. Using a Rotobrush agitation tool and a HEPA-filtered vacuum under negative pressure, our tech pulled compacted debris out of both legs, then ran a camera inspection at the return near the air handler so the homeowner could see the supply and return ducts were actually clear before we buttoned everything back up.
