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 Leesburg, VA
A full system cleaning addresses every component in your home’s air distribution network in a single visit: the supply and return duct runs, the main trunk lines, the air handler cabinet, the blower assembly, the evaporator coil housing, and every register and grille in the house. In Leesburg, most homes built between 1995 and 2015 are overdue for Air Duct Cleaning services at this level – a partial cleaning that skips the air handler or the return plenum just recirculates what was left behind. If you’d like a written price before committing to anything, call (571) 487-7204 and a live person will pick up.
CleanRun Duct Repair & Cleaning has been doing this work since 2013, and the standard we hold ourselves to hasn’t changed: every duct run photographed before we touch it, every run photographed again when we’re done, written price agreed before any panel comes off. That’s the Haven Standard, and it applies to every full system cleaning we do in Leesburg and the surrounding area. For a broader look at what we offer, our Air Duct Cleaning in Leesburg page covers the full scope of services.
Tomas Reyes leads every job under that standard. When the truck pulls up, you’ll know who’s coming in because we send a name and a photo before arrival – Haven Standard Clause 3: Verified Crews.
When You Need Full System Cleaning
Not every home needs a full system cleaning at the same interval. Here are the situations where a partial cleaning won’t be enough – and where doing the whole system in one visit is the only approach that produces a documented result.
- You’ve never had the ducts cleaned since purchasing the home. Leesburg’s housing stock includes a lot of large colonials and Craftsman-style builds from the late 1990s through the mid-2000s, many sold with the original ductwork still in place. If you bought the house between 2015 and 2025 and the inspection report didn’t include a duct camera, there’s no record of what’s in there. Our camera shows you before we say a word about what’s next.
- You’ve had renovation or construction work done inside the house. Drywall dust and construction debris travel through return ducts faster than most homeowners expect. After a kitchen gut or a finished basement project, that material is in the trunk lines and sometimes packed into the first elbow behind the register.
- Allergy or asthma symptoms are worse inside than outside. Leesburg sits in Loudoun County, which carries one of the higher seasonal pollen loads in Northern Virginia – oak and grass pollen through spring, ragweed through late summer. When duct debris is already present, that seasonal load compounds. A full system cleaning removes the accumulated base layer, which is the part you can actually control.
- The HVAC system is running longer cycles to reach temperature. A debris-restricted return or a fouled blower wheel forces the air handler to work harder and move less air. If your energy bills have crept up and the system is relatively new, the ductwork is worth inspecting before calling an HVAC tech.
- You’ve noticed uneven airflow or odors from specific vents. Musty or dusty smells localized to certain registers often point to debris or moisture accumulation in a specific duct run – sometimes near a crawl space or an unconditioned attic section, both of which are common in older Leesburg neighborhoods like Exeter and Tuscarora Creek.
- A previous cleaning was done with a shop vac or a low-power portable unit. The $79 coupon model generates noise, not airflow. Negative-pressure extraction requires a truck-mounted or high-draw unit pulling several thousand CFM across the system while agitation tools work inside the duct. If you weren’t shown equipment specs and before-and-after photos last time, there’s no evidence anything was removed.
Our Full System Cleaning Process
Here is exactly what happens on a full system cleaning in Leesburg, in the order it happens. Nothing starts until you’ve seen the written price and agreed to it – that’s Haven Standard Clause 1, and it applies without exception.
- Pre-job walkthrough and camera inspection. Before any equipment enters the ductwork, we walk the system with you – locating every supply and return register, identifying the air handler position, and noting any visible damage to grilles or flex duct connections. We then run a camera through the accessible duct runs and photograph what’s inside. You see the debris, the buildup at elbows, any visible microbial growth or pest intrusion, before we describe what the job involves. This is the documented baseline that makes the after-photos meaningful.
- Written price, agreed before work starts. Based on the camera inspection and the system layout, we produce a written scope and a flat price. In Leesburg, full system cleaning for a single-family home is typically quoted as a single line item with any add-ons listed separately – sanitizing, coil cleaning, dryer vent work. Haven Standard Clause 1: the number doesn’t change after the work starts unless the scope changes, and if it does, you approve the change in writing before we proceed.
- Negative-pressure extraction setup. We connect a high-draw extraction unit – Nikro or Abatement Technologies equipment, depending on the job – to the main trunk line or a central access point, pulling the system into negative pressure. This means the entire duct network is under suction before we introduce any agitation tools. Negative pressure keeps loosened debris moving toward the collection point rather than scattering back into the living space.
- Mechanical agitation through every duct run. With the system under negative pressure, a Rotobrush rotary brush system works through each supply and return duct run individually. The brush loosens debris from duct walls while the extraction unit draws it out. We cover every run – not a sample set, every run. In a 2,500-square-foot Leesburg colonial with 18 supply registers and 4 returns, that means every run gets individual attention before we move to the next section.
- Air handler cabinet, blower, and coil housing cleaning. The air handler cabinet is where a lot of partial cleanings stop short. We open the cabinet, clean the blower wheel (a fouled blower wheel can reduce airflow by 20-30% without triggering any error code), clean the accessible surfaces of the evaporator coil housing, and clear any debris from the drain pan area. If sanitizing is in the scope, it’s applied here as well as to the duct surfaces.
- Post-job camera documentation and photo record delivery. After every run is cleaned and the air handler is reassembled, we run the camera again through the same positions we photographed at the start. You receive a before-and-after photo record of every duct run as a standard deliverable – not an upgrade, not an emailed PDF you have to request. It’s part of the job. This record is also what backs the 365-Day Done Right Promise: if something wasn’t done right, the photos show it, and we make it right in writing.

AfterFull System Cleaning Pricing in Leesburg
Full system cleaning in Leesburg costs between $350 and $750 for most single-family homes, with the range driven by system size, number of duct runs, air handler configuration, and whether the job includes any add-on services. Here is how the numbers break down in practice.
| Home Size / Scope | Typical Price Range | Notes |
|---|---|---|
| Townhouse or condo, up to 1,500 sq ft | $350 – $450 | Single air handler, 10-14 supply/return runs |
| Single-family home, 1,500 – 2,500 sq ft | $450 – $575 | Single system, 15-22 runs; most common Leesburg scope |
| Single-family home, 2,500 – 4,000 sq ft | $550 – $700 | Often two-zone or dual-system; each air handler cleaned separately |
| Large home, 4,000+ sq ft or dual system | $650 – $750+ | Full dual-system cleaning with documentation on both units |
| Add-on: antimicrobial sanitizing (per system) | $75 – $120 | Applied to duct surfaces and air handler cabinet |
| Add-on: dryer vent cleaning (same visit) | $89 – $139 | Priced separately; often combined to avoid a second truck visit |
A few things that affect where your job lands in these ranges: homes with long horizontal duct runs in unconditioned attic space – a common configuration in Leesburg subdivisions like River Creek and Lansdowne Woods – take longer to agitate and extract than compact vertical systems. Older flex duct in poor condition sometimes needs to be worked around rather than brushed aggressively, which affects time. And if a previous partial cleaning left compacted debris at specific access points, that adds time at those locations.
What doesn’t vary: your price is written before we start. If you have a competitor’s written estimate, bring it. We put our number next to it in writing – that’s our Free Second Opinion, and it doesn’t cost anything.

What CleanRun’s Documentation Actually Looks Like
The phrase “before and after photos” gets used loosely in this industry, so it’s worth being specific about what CleanRun delivers. After a full system cleaning in Leesburg, you receive a photo record that shows each duct run by register location – labeled by room, by floor, and by whether it’s a supply or return. The camera captures the first elbow, the mid-run section, and the far end of each run where accessible. The after photos are taken from the same positions as the before photos, so the comparison is direct.
You also receive the written scope that was agreed before work started, the written price, and documentation of the 365-Day Done Right Promise. This is the record that travels with the house – useful when you sell, useful if you have an insurance question about indoor air quality, and useful if anything ever comes up with the system in the twelve months after the job.
Tomas Reyes has held this documentation standard since CleanRun’s first job in 2013. In that time, the team has worked on more than 52,000 homes. The photo record isn’t a marketing feature – it’s how we show that the work was done, not just performed.
If you’re comparing this to a competitor’s approach, ask them one question: what does the customer receive as evidence that the duct runs were cleaned, not just accessed? If the answer is a verbal assurance or a generic before-and-after of a single register, that’s a meaningful difference worth weighing before you decide. Our home page outlines the full Haven Standard if you want the complete picture of how every job is structured.
FAQs – Full System Cleaning in Leesburg
How long does a full system cleaning take for a typical Leesburg home?
A full system cleaning for a 2,000-2,500 square foot single-family home in Leesburg typically takes 3 to 4 hours from setup to final documentation. Larger homes with dual systems or extensive duct runs – common in some of the larger homes in Lansdowne and Potomac Station – can run 5 to 6 hours. We don’t quote time ranges to pressure a sale; we quote them because the photo documentation has to cover every run, and that can’t be rushed without skipping something that shows up in the after-photos. Call (571) 487-7204 for a time estimate tied to your specific layout.
How much does full system cleaning cost in Leesburg?
Full system cleaning in Leesburg runs $350 to $750 for most single-family homes, depending on square footage, number of duct runs, and whether the job includes add-on services like sanitizing or dryer vent cleaning. Your exact price is written and agreed before any work starts – Haven Standard Clause 1, no exceptions. If you have a written estimate from a competitor, we’ll put our number next to it in writing at no charge. Call (571) 487-7204 for a free written estimate on your home’s system.
Is full system cleaning different from a standard duct cleaning?
Full system cleaning includes the air handler cabinet, blower wheel, and evaporator coil housing in addition to the duct runs and registers – components that a standard or partial cleaning often skips. A cleaning that doesn’t address the blower or the air handler leaves the contamination source in place and puts debris back into the duct network every time the system runs. CleanRun’s full system cleaning covers all of it in a single visit, with before-and-after documentation on every component accessed. For context on what a standard duct cleaning includes, see our Air Duct Cleaning in Leesburg service page.
How often should a Leesburg home have a full system cleaning?
For most Leesburg homes, a full system cleaning every 4 to 6 years is reasonable – but that interval shortens in specific situations. If you have pets that shed, children with documented respiratory conditions, a home near a high-pollen corridor (which describes much of the Rt. 15 and Rt. 7 areas in Loudoun County), or a recent renovation, 3 years is a more appropriate target. The before-photos from your last cleaning are the best guide: if the duct walls showed significant buildup at the 4-year mark last time, they’ll accumulate at roughly the same rate next cycle. We keep your documentation on file so there’s an actual baseline to compare against.
What equipment does CleanRun use for full system cleaning?
On a full system cleaning in Leesburg, we use a Rotobrush rotary agitation system inside the duct runs and a high-draw negative-pressure extraction unit – typically Nikro or Abatement Technologies, depending on the system configuration. These are trade-recognized brands you can look up independently before agreeing to a price. We name the equipment because Haven Standard Clause 1 applies to the scope as well as the price: you should know what’s going into your home before we start.
If your Leesburg home is due for a full system cleaning – or if you’re not sure whether a partial cleaning actually addressed the whole system – call (571) 487-7204. A live person answers every call, we’ll give you a written price based on your home’s layout, and the job doesn’t start until you’ve seen it in writing. The 365-Day Done Right Promise backs every full system cleaning we do.
