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.

AfterFull System Cleaning in Ashburn, VA
Full system cleaning means every component that moves air through your home gets cleaned in a single visit: supply ducts, return ducts, the air handler, blower assembly, evaporator coil housing, and every register from the plenum – the central distribution box connected to your furnace or air handler – all the way out to the last supply vent in the farthest bedroom. In Ashburn, where newer construction in developments like Brambleton, Moorefield Station, and One Loudoun often means long duct runs with tight turns, a partial cleaning that stops at the main trunk lines leaves a significant percentage of the system untouched. CleanRun Air Duct Cleaning services in Ashburn has cleaned full systems in Ashburn homes since 2013, and the before-and-after photo record we deliver with every job shows exactly what was found and what left with us.
If you want to understand how full system cleaning fits into the broader scope of what we do, the Air Duct Cleaning in Ashburn page walks through the service category in full. For a written price on your specific home – square footage, number of duct runs, system configuration – call (240) 771-1508. A live person answers, the quote is written before any work starts, and there is no version of this where you get a number only after the crew is already in your crawl space.
When You Need Full System Cleaning
Not every home needs a full system cleaning every year. But certain conditions in Ashburn homes make a thorough, whole-system approach the only option that actually addresses the problem.
- You moved into a resale home and the duct cleaning history is unknown. Ashburn’s resale market moves quickly, and disclosure forms rarely include HVAC maintenance records. Camera inspection in homes that changed hands in 2019-2023 routinely shows debris accumulation at the first elbow off the plenum that dates back several HVAC filter cycles.
- Your home was built between 2010 and 2020 and has never had its ducts cleaned. Loudoun County saw heavy residential construction through this period, and construction dust – drywall particulate, insulation fragments, wood shavings – settles into duct runs during the build and stays there unless it’s mechanically extracted. A filter does not remove what is already inside the system.
- You’re noticing uneven temperatures between rooms. In Ashburn homes with two-story layouts common in Moorefield Station, restricted airflow from debris buildup at branch takeoffs – the points where the main trunk splits toward individual rooms – can create a 4 to 6 degree difference between the first floor and upper bedrooms. That is often a duct issue, not a thermostat issue.
- A family member with asthma, allergies, or a respiratory condition is reacting more indoors than outdoors. The EPA has documented that indoor air can carry significantly higher concentrations of certain particulates than outdoor air in comparable suburban areas. A full system cleaning addresses the supply side, the return side, and the blower – all three pathways where particulates recirculate.
- You had recent renovation work inside the home. Tile cutting, drywall removal, and hardwood sanding in Ashburn’s older Broadlands or Ryan Park homes push fine dust directly into return air registers. That material moves through the blower and deposits throughout the system. A partial cleaning after renovation leaves the contamination source intact.
- Your last “duct cleaning” was a $79 coupon job. In Loudoun County, the low-price duct cleaning model is well established. It typically involves a shop vac attached to two or three registers and takes under an hour for a 2,500 square foot home. A full system cleaning using negative-pressure extraction – where the entire system is placed under negative pressure before agitation begins so debris is pulled out rather than redistributed – takes three to five hours in the same home. The photo record tells you which one happened.
Our Full System Cleaning Process
Every full system cleaning CleanRun performs in Ashburn follows the same documented sequence. Nothing is skipped to save time, and the photo record captures each phase before we move to the next.
- Pre-job camera inspection and written scope. Before a panel comes off or a register is pulled, we run a camera through the accessible duct runs and photograph what we find. If there’s a 2-inch debris layer at the return plenum or visible mold growth at a supply elbow near the air handler, you see that photo before we quote the work. The written price you receive under Haven Standard Clause 1 is based on what the camera actually showed, not on a square footage estimate made from the curb.
- System isolation and negative-pressure setup. We connect our collection unit – we use Nikro negative-pressure equipment on Ashburn jobs – to the main trunk or plenum access point and bring the entire duct system to negative pressure before any agitation starts. Negative pressure means the interior of the system is at lower air pressure than the surrounding room, so when debris is dislodged it moves toward the collection unit rather than back into your living space. Every register is sealed with temporary covers during this phase.
- Mechanical agitation of every duct run. With the system under negative pressure, we work through each supply and return run using rotary brush equipment. Rotobrush tools are specifically designed for flexible and rigid duct systems, and the brush diameter is selected to match the duct size rather than using one size across the whole job. In Ashburn homes with a mix of hard metal trunk lines and flexible branch ducts – a common configuration in post-2005 construction – this step requires changing tools between the trunk and the branch runs. We do that. A tech who uses one brush size throughout is not cleaning the branch runs effectively.
- Air handler, blower, and evaporator coil housing. The air handler is where every cubic foot of air in your home passes through the system. The blower wheel – the fan that moves air – accumulates debris on its blades over time, which reduces airflow efficiency and recirculates particulate on every heating and cooling cycle. We clean the blower wheel, the housing, and the accessible surfaces of the evaporator coil cabinet as part of the full system scope. This step is frequently skipped in discount cleaning jobs; it is not optional in ours.
- Register and grille cleaning. Every supply and return register is removed, cleaned of dust and debris accumulation, and reinstalled. In Ashburn homes with painted metal registers – common in older Broadlands construction from the early 2000s – paint buildup on the fins can restrict airflow by 10 to 15 percent. Cleaning them is part of the job.
- Post-job camera verification and photo record delivery. We run the same camera inspection after the cleaning that we ran before it. The before and after photos are documented together and delivered to you as part of the standard job record – not as an optional add-on. You can see the first elbow, the main trunk, the return plenum, and the branch takeoffs in both states. If the after photos don’t show a clean system, the 365-Day Done Right Promise is the mechanism: we come back and make it right, in writing, not subject to manager approval.
BeforeAfterFull System Cleaning Pricing in Ashburn
Full system cleaning in Ashburn runs between $350 and $750 for most single-family homes, with the range driven by system size, number of duct runs, and access conditions. Here is how the pricing breaks down in practice:
| Home Configuration | Typical Range |
|---|---|
| Single-story home, 1,200-1,800 sq ft, one system, 8-12 runs | $350-$450 |
| Two-story home, 2,000-2,800 sq ft, one system, 14-20 runs | $450-$600 |
| Two-story home with basement, 3,000+ sq ft, dual system, 22-30+ runs | $600-$750 |
| Sanitizing treatment (Abatement Technologies EPA-registered product, applied to interior duct surfaces after cleaning) | $80-$150 added to base |
What moves a job toward the higher end of a range: dual-zone HVAC systems (common in larger Ashburn homes in Willowsford or The Grove at Lakeview), heavily contaminated systems where the post-agitation pass requires a second equipment setup, or systems with inaccessible branch runs in finished ceilings that require additional access work.
What does not move the price: adding the blower cleaning, the register cleaning, or the post-job photo record. Those are included. They are not line items we add after the crew is on site.
Haven Standard Clause 1 means the written price is delivered before any work starts – every time, without exception. There is no version of a CleanRun job where the number changes when the invoice appears. If you have a written estimate from another company, bring it. We’ll put our number next to it in writing at no cost – that is the free second opinion, and it is available to any Ashburn homeowner who requests it.
Call (240) 771-1508 to get your written estimate. We’ll ask about your home’s square footage, number of stories, system type, and the last time the ducts were serviced – and you’ll have a written number before we schedule anything.
FAQs – Full System Cleaning
How is full system cleaning different from a standard duct cleaning?
Full system cleaning covers every air-carrying component in the system: supply ducts, return ducts, the air handler, blower assembly, evaporator coil housing, and all registers. A standard duct cleaning – particularly the discount-coupon variety common in Ashburn – typically addresses only the accessible Supply Duct Cleaning runs using a portable vacuum, leaving the return side, the blower, and the air handler untouched. The difference is not a matter of degree; it’s a different scope of work. In practical terms: if the blower wheel is coated in particulate buildup and the return plenum hasn’t been touched, every cubic foot of air that moves through your system after a “standard” cleaning still passes through contaminated components. Call (240) 771-1508 to get a written quote that specifies exactly what is included in scope.
How long does a full system cleaning take in an Ashburn home?
A full system cleaning in a typical Ashburn single-family home – two stories, one HVAC system, 14 to 18 duct runs – takes three to four hours. Larger homes with dual systems, such as those in Willowsford or Brambleton’s larger floor plans, run four to five hours. Homes with heavily contaminated systems or difficult access conditions can run longer. We build time estimates into the written quote so you know what to expect before the crew arrives – not as a rough guess, but as a documented part of the job scope.
Do I need to do anything to prepare my home before the cleaning?
Clear a few feet of space around each supply and Return Duct Cleaning register so the tech can pull them without moving furniture mid-job. If you have pets, keep them in a room away from the main work area – the negative-pressure setup is loud, and pets near open register openings can be startled by the airflow shift. Beyond that, you don’t need to do anything. The pre-job camera inspection happens before any equipment is set up, so there’s no prep work the homeowner needs to complete for us to get an accurate read on what’s inside the system. If you’re in Ashburn’s Moorefield Station area where some homes have second-floor air handlers in closet spaces, just make sure that closet is accessible – that’s the one access point we’ll need clear.
How often should a full system cleaning be done in an Ashburn home?
Most Ashburn homes benefit from a full system cleaning every three to five years under normal occupancy conditions. That interval shortens with pets (pet dander and hair accumulate at blower intakes faster than most homeowners expect), recent renovation work, or if a family member has a respiratory condition that makes air quality a medical consideration. New construction or recently purchased resale homes in Ashburn are a different case: we frequently find construction-phase debris in systems that have never been cleaned regardless of the home’s age, and those should be addressed before the three-to-five-year clock starts. Call (240) 771-1508 for a written assessment – the pre-job camera inspection tells us more about your system’s actual condition than any general guideline can.
Does the 365-Day Done Right Promise cover full system cleaning?
Yes. Every full system cleaning job CleanRun performs in Ashburn is covered by the 365-Day Done Right Promise: if the work is not done right, we come back and make it right. That promise is in writing on every job – it is not a policy subject to review or a warranty that requires a manager to approve. The post-job photo record is the documentation that anchors it: if there’s a question about what was cleaned and what wasn’t, the before and after images of each duct run are part of the job record we deliver to you the same day the crew leaves.
What the Photo Record Actually Shows
A lot of companies describe the work. CleanRun documents it. The photo record included with every full system cleaning in Ashburn captures the interior of each duct run before the crew starts and again after the job is complete. That means the first elbow off the plenum, the main trunk in both directions, the return plenum, and the branch takeoffs to individual rooms – photographed, labeled, and delivered as part of the standard job package.
In Ashburn homes that have gone through a discount cleaning previously, the before photos occasionally show something instructive: the main trunk near the air handler is clean where a shop vac was held against the register, and the debris line starts clearly at the point the hose could no longer reach. The branch runs – the flexible ducts that carry air to the last bedroom or the bonus room above the garage – are untouched. Those photos don’t require explanation. They document exactly what was done on the previous visit and what wasn’t.
This practice – photographing the inside of every run, not just the access points – is something CleanRun has done since its first job in 2013, covering more than 52,000 homes. It is not a marketing feature. It is the mechanism that makes the 365-Day Done Right Promise something you can actually hold us to.
The equipment behind that record includes Rotobrush rotary systems for mechanical agitation and Abatement Technologies collection and negative-pressure units – professional-grade tools you can look up independently before agreeing to a price. We name the brands because the equipment matters, and because a company that won’t tell you what it’s using before you sign anything is telling you something about how it operates.
