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.

AfterCommercial Duct Cleaning in Ashburn, VA
Commercial duct cleaning in Ashburn, VA typically runs between $800 and $4,500 depending on building size, duct configuration, and how long the system has gone without service. Most light-commercial jobs – office suites, retail bays, and small medical offices in the 2,000-to-8,000-square-foot range – are completed in a single day. CleanRun documents every duct run with before-and-after photos so you have a written record of what was removed, not just a bill saying the work was done.
If you operate a business in Ashburn and your HVAC system is pushing air through ducts that haven’t been inspected in three or more years, this page covers what the cleaning process actually looks like, what it costs in this market, and what you’ll have in hand when the crew leaves. For context on how our residential and commercial work connects, the Air Duct Cleaning in Ashburn page explains our full-service approach and the standards that apply to every job we run.

When You Need Commercial Duct Cleaning
Commercial systems accumulate debris faster than residential ones for straightforward reasons: more people, more traffic, more air changes per hour, and in Ashburn’s case, a lot of new construction that left drywall dust in ductwork that was never cleaned after build-out. Air duct cleaning removes this buildup before it affects air quality. Here are the situations we see most often:
- Post-construction or post-renovation debris: Construction dust, joint compound particles, and insulation fibers migrate into duct runs during any build-out. In Ashburn’s One Loudoun corridor and along Loudoun County Parkway, we regularly find a visible grey cake of drywall particulate at the first plenum elbow – the central chamber where supply air splits into individual runs – on spaces that have been occupied for two or three years without a post-construction clean.
- Visible dust discharge at supply registers: When you can see a halo of grey or brown residue on the ceiling tile around a supply register, the duct liner or internal surfaces upstream are shedding into the airstream. That’s not a filter problem – it’s a duct problem.
- Persistent odor despite clean filters: Mold growth, pest infiltration, or accumulated biological material inside the ductwork will push a stale or musty smell into the space regardless of how often filters are changed. We’ve opened return plenums in Ashburn office parks and found debris loads that no filter upstream would ever catch.
- HVAC system running harder than it should: Debris build-up inside ducts increases static pressure – the resistance the fan works against. When static pressure climbs, the system runs longer cycles, energy costs go up, and equipment life comes down. A 3-inch debris build-up at a trunk line elbow can measurably reduce airflow to the rooms beyond it.
- Lease turnover or change of business type: A restaurant or salon moving out of a space leaves cooking grease, chemical aerosols, or hair and product residue in the ductwork. If you’re leasing a space with an HVAC history you don’t know, cleaning before you move people in is the right call.
- Three or more years since the last documented cleaning: NADCA guidelines recommend commercial duct inspection every two to four years depending on occupancy type. If there’s no photo record of the last cleaning, there’s no evidence a real cleaning happened – and a shop-vac-and-blower visit from a $79-coupon operation doesn’t count.
Our Commercial Duct Cleaning Process
The process below is the same on every commercial job we run in Ashburn. Steps don’t get skipped because a space is small or a schedule is tight. This is what a documented cleaning looks like under the H.A.V.E.N. Standard.
- Pre-job walkthrough and written scope: Before any panel comes off, Tomas Reyes or the lead technician walks the mechanical space, counts supply and return runs, identifies the air handler make and configuration, and notes any known issues – flex duct sections, damaged dampers, prior pest activity. That walkthrough produces a written scope and a written price, delivered before work starts. Haven Standard Clause 1: no work begins without a written price in the customer’s hand.
- Pre-cleaning photography of every duct run: We open each supply and return register and photograph the interior with a duct camera before touching anything. The before-photo record is the baseline. It shows the debris load, the condition of the liner, and whether there’s visible mold, pest evidence, or mechanical damage. These photos are part of your job record and are delivered to you at the end of the visit – not stored somewhere on our server where you’d have to request them.
- Negative-pressure extraction setup: We connect professional-grade negative-pressure equipment – which uses a powerful vacuum to pull air and debris toward a collection point rather than pushing it around – at the main trunk or plenum. Our equipment roster includes units from Abatement Technologies and Nikro, both of which are rated for commercial duct volumes. The negative-pressure configuration means that when we agitate debris in a branch run, it travels toward the collection unit, not into the occupied space.
- Mechanical agitation of every branch run: We use a Rotobrush rotary brush system to break debris loose from duct walls. Rotobrush equipment is specifically built for this: a rotating brush on a flexible cable that reaches branch runs at length, combined with continuous vacuum extraction. We work every accessible run – not just the ones close to the air handler. Inaccessible sections are documented and flagged in the job record.
- Air handler and plenum cleaning: The air handler cabinet – the metal box that houses the blower, coil, and filter rack – is cleaned separately. Debris that bypasses filters accumulates on the coil fins and blower wheel. We clean both and photograph the result. The plenum (the main distribution chamber the air handler feeds into) is inspected and cleaned as part of this step.
- Post-cleaning photography and written job record: After every run is cleaned, we re-photograph each one with the same duct camera used in step two. You get a side-by-side before-and-after record for every run. The written job record includes the scope of work completed, any deficiencies noted (damaged flex duct, failed dampers, open seams), and the 365-Day Done Right Promise in writing – if anything about the work isn’t right, we make it right. That commitment is on paper, not stated verbally in a driveway.
BeforeAfterCommercial Duct Cleaning Pricing in Ashburn
Commercial duct cleaning in Ashburn costs more than residential duct cleaning because commercial systems are larger, more complex, and typically require more access time. Prices below reflect the Ashburn market. Every number on this page reflects what we actually charge – written upfront, before work starts, every time.
| Space Type / Size | Typical Price Range | Notes |
|---|---|---|
| Small office suite (under 2,000 sq ft) | $800 – $1,400 | Single air handler, standard duct layout |
| Mid-size office or retail (2,000 – 5,000 sq ft) | $1,400 – $2,500 | Multiple units or rooftop packaged systems common |
| Larger commercial (5,000 – 10,000 sq ft) | $2,500 – $4,500 | Multi-zone, multi-handler; price depends on duct run count |
| Post-construction clean (any size) | Add $200 – $600 to base | Higher debris loads require additional extraction time |
| Antimicrobial treatment (optional) | $150 – $400 | EPA-registered products, applied after cleaning is confirmed |
What moves a price higher: rooftop packaged units that require ladder access, ductwork installed above a drop ceiling that requires tile removal, older galvanized duct with heavy oxide scale build-up, or systems that haven’t been serviced in more than five years. What keeps a price lower: newer duct systems with good access panels, spaces that received a full system cleaning within the last three years with documented records.

FAQs – Commercial Duct Cleaning in Ashburn
How long does commercial duct cleaning take for an average Ashburn office?
A standard office or retail suite under 3,000 square feet takes between three and six hours from setup to final photo documentation. Larger spaces with multiple air handlers – common in Ashburn’s Route 7 and Broadlands-area office parks – typically run a full day, sometimes two, especially if return duct cleaning is needed alongside supply runs. We give you a time estimate in the written scope before work begins so you can plan around the crew’s presence. Call (240) 771-1508 for a site-specific estimate.
Do you work around business hours so we don’t have to close?
Yes. Early-morning start times and weekend scheduling are available for Ashburn businesses that can’t afford downtime during operating hours. Negative-pressure extraction is significantly quieter than the leaf-blower-and-shop-vac approach some contractors use, so partial operation during cleaning is possible depending on your layout – something we discuss during the pre-job walkthrough. The written scope will note any operational constraints.
What’s actually included in the written job record you deliver?
The job record includes: before-and-after photographs of every duct run cleaned, a written description of any deficiencies found during the job (open seams, collapsed flex runs, failed dampers), confirmation of the equipment used, and the 365-Day Done Right Promise in writing. You receive this as a standard deliverable at the end of the visit – it’s not an add-on and there’s no request process. This is what differentiates documented work from a handshake and an invoice.
Is commercial duct cleaning required by code in Ashburn or Loudoun County?
Loudoun County does not mandate commercial duct cleaning on a fixed schedule, but NADCA (National Air Duct Cleaners Association) guidelines recommend inspection every two to four years for occupied commercial spaces, and more frequently for food-service, medical, or high-particulate environments. Some commercial leases and property management agreements require documented cleaning at tenant turnover. If your lease has such a clause, the job record we deliver satisfies that documentation requirement. For questions about specific permit or inspection requirements in your building, the Loudoun County Department of Building and Development is the right contact.
What You’ll Have When the Truck Leaves
Most commercial cleaning companies hand you an invoice and a phone number to call if something seems off. That’s the standard. CleanRun operates differently, and the difference is concrete: you’ll have a before-and-after photo record for every duct run in your system, a written scope of work with every finding documented, and the 365-Day Done Right Promise backed in writing – not verbally, not subject to manager discretion, in writing.
Tomas Reyes has run CleanRun since 2013, and the documented-record approach has been part of every job since the first one. Over 52,000 homes and commercial spaces served means the process is established – not a trial run on your building. Every technician who shows up at your Ashburn property is background-checked, uniformed, and identified by name before arrival, in accordance with Haven Standard Clause 3: Verified Crews.
If you’ve been quoted a suspiciously low number by a competitor, consider what’s in that price. A $79 commercial duct cleaning in a 4,000-square-foot space is arithmetically incompatible with the equipment time and labor required to clean the system properly. We’ll put our number next to theirs in writing and show you exactly where the difference comes from.
