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.

AfterTrusted Air Duct Cleaning for Leesburg Homeowners
Air duct cleaning in Leesburg, VA typically costs $380-$720 for a complete residential system and takes 3-5 hours. CleanRun Duct Repair & Cleaning has served Leesburg homeowners since 2013 with a written price delivered before any work starts and a documented photo record of every duct run included as standard. Call (571) 487-7204 for a free estimate with no obligation.
We’ve cleaned ducts in more than 52,000 homes, and the pattern in Leesburg is consistent: newer construction in neighborhoods like Lansdowne, Woodlands, and Beacon Hill often shows heavy construction debris left in ductwork from the build, while older homes near downtown and along Route 15 collect decades of settled dust that standard HVAC filters never catch. The Potomac River humidity and seasonal pollen loads here mean ducts that look clean at the register can harbor substantial buildup at the plenum - the central distribution box where all duct runs connect - and at the first elbow of each run where airflow changes direction. Our crews document this with before-and-after photography on every visit, so homeowners see exactly what was inside their system.
Tomas Reyes leads CleanRun as an independently owned and operated company under the Haven Standard. Every technician is background-checked, uniformed, and identified by name before arrival - Haven Standard Clause 3: Verified Crews. The 365-Day Done Right Promise applies to every job in writing, not as a verbal assurance.
What Our Air Duct Cleaning Service Includes
Residential Duct Cleaning
Residential Duct Cleaning covers the complete network of supply and return ducts, registers, and the main plenum in single-family homes, townhouses, and condominiums. Most Leesburg homes built between 2015 and 2025 have flexible ductwork with multiple bends where debris accumulates, particularly in multi-story designs common in South Riding and Lansdowne. We use negative-pressure extraction - a vacuum system that pulls contaminants out while agitation tools loosen them - with Rotobrush and Nikro equipment, photographing the interior of every duct run before and after.
Commercial Duct Cleaning
Commercial Duct Cleaning addresses the larger-scale HVAC systems found in office buildings, retail spaces, medical offices, and multi-tenant properties along Route 7 and near Leesburg Executive Airport. These systems typically feature sheet metal trunk lines with multiple branches, requiring higher-capacity Abatement Technologies vacuums and extended reach tools. We schedule commercial work to minimize disruption, often during evening or weekend hours, and provide the same documented photo record with a written scope of work delivered before any panels are removed.
Supply Duct Cleaning
Supply ducts carry heated or cooled air from your HVAC unit to each room, and they often show the heaviest debris accumulation because they operate under positive pressure - pushing air out rather than pulling it in. In Leesburg’s newer subdivisions, we’ve found construction debris including drywall dust, wood chips, and insulation fragments blocking supply runs years after move-in. Our crews remove each register, inspect with a borescope camera, and clean the full length to the plenum connection, with photos showing the condition at each stage.
Return Duct Cleaning
Return ducts pull air back to the HVAC unit for reconditioning, making them the primary collection point for household dust, pet dander, and airborne particles. Because return ducts are typically larger and often include filter grilles that homeowners can see, they’re frequently assumed to be cleaner than supply lines - in practice, the opposite is often true. We clean the full return path including the return plenum and filter rack area, where gaps in the filter seal allow bypass debris to accumulate on the blower and coil.
Full System Cleaning
Full System Cleaning encompasses supply ducts, return ducts, the plenum, registers, grilles, and accessible components of the air handler including the blower assembly and coil housing. This is the service most Leesburg homeowners need when they haven’t had professional duct cleaning in 5+ years or when moving into a previously occupied home. The full system scope includes more duct runs and takes longer, but it eliminates the risk of recontaminating cleaned sections through dirty upstream components. We quote this as a flat price per system, not per vent, with the written scope detailing every component included.
Video Inspection
Video inspection uses a flexible borescope camera to document the interior condition of ductwork without disassembly, providing visual evidence of debris levels, construction debris, mold growth, or duct damage. We recommend this for homeowners who are uncertain whether cleaning is needed, for real estate transactions common in Leesburg’s active market, or when a previous cleaning by another company left doubts about thoroughness. The video file becomes part of your job record and can be referenced for future comparison.

Brands We Service for Air Duct Cleaning
CleanRun technicians work with duct systems connected to all major HVAC brands, and we maintain specific expertise with several manufacturers whose equipment is common in Leesburg homes. We’ve serviced hundreds of Aprilaire whole-home air cleaner and ventilation systems, including their media air cleaners and dehumidifiers integrated into ductwork - we stock Aprilaire replacement media and understand how their bypass and direct-drive configurations affect cleaning access. Our crews also regularly work with Abatement Technologies HEPA filtration and containment equipment, particularly in commercial settings where their portable air scrubbers supplement duct cleaning during renovation or remediation projects.
Guardsman UV air treatment systems installed in Leesburg ductwork require careful handling during cleaning to avoid damaging lamps or quartz sleeves, and our technicians are trained to remove, protect, and reinstall these components without compromising their seal. Rotobrush brush-and-vac systems are among our primary cleaning tools, not a brand we service as HVAC equipment, but worth naming because customers can verify their specifications independently. Whether your home has Aprilaire, Abatement Technologies, Guardsman, or any other make of air handling or air quality equipment, we can clean the connected ductwork without voiding warranties or damaging components.

AfterSigns You Need Air Duct Cleaning Right Now
- Visible dust blowing from registers when the system starts. This indicates debris buildup in the supply ducts that has exceeded the system’s capacity to contain it. In Leesburg’s newer construction, this often appears within the first 2-3 years as leftover construction material works loose.
- Uneven heating or cooling between rooms on the same floor. When some duct runs are partially blocked by debris, airflow becomes unbalanced and rooms at the end of restricted lines stay too hot or too cold. We’ve found 40-60% airflow reductions in individual runs where debris had accumulated at the first elbow.
- Musty or stale odors when the HVAC system cycles on. Organic material in ductwork, including dust mite debris, pet dander, and pollen, produces noticeable odors when heated or humidified. The Potomac River valley humidity in Leesburg accelerates this process compared to drier inland climates.
- Recent home renovation or construction, even in a neighboring unit. Fine particulate from drywall sanding, flooring installation, or exterior work enters ductwork through return grilles and settles in the plenum. We regularly clean post-renovation systems where the contractor’s protection was inadequate.
- You’ve never had professional duct cleaning, or it’s been more than 5 years. The NADCA, the trade association for duct cleaning professionals, recommends cleaning every 3-5 years under normal conditions. Homes with pets, allergies, or recent construction need more frequent service.
Our Air Duct Cleaning Process - Step by Step
- 1
Written price delivered before work begins. Haven Standard Clause 1 requires a flat price per system, agreed in writing, with every component listed. You’ll know the full cost before a single panel comes off. No per-vent add-ons, no equipment surcharges, no “while we’re here” upsells.
- 2
Pre-cleaning photo documentation of every duct run. Our technician photographs the interior of each supply and return run through the register opening, using a borescope camera with a timestamp. These images go into your job record and are available for your review before we proceed.
- 3
System isolation and negative-pressure setup. We seal registers and connect a high-capacity vacuum to the main trunk line, creating negative pressure throughout the duct network. This containment method prevents debris from escaping into your home during cleaning.
- 4
Agitation and extraction with professional-grade equipment. Rotobrush and Nikro tools dislodge debris from duct walls while the vacuum pulls it into a sealed collection container. We adjust brush stiffness and vacuum power based on duct material - flexible ductwork in newer Leesburg homes requires gentler handling than metal systems.
- 5
Post-cleaning verification photography and written record. Every duct run is photographed again after cleaning, with timestamps matching the pre-cleaning sequence. The complete photo record, written scope, and 365-Day Done Right Promise documentation are delivered before the crew leaves.
How Much Does Air Duct Cleaning Cost in Leesburg?
A typical residential full system cleaning in Leesburg runs $380-$720 depending on system size, duct configuration, and accessibility. Smaller single-level homes with 8-12 duct runs and basement access for the air handler fall at the lower end. Larger homes in Lansdowne or Beacon Hill with 20+ runs, multiple zones, and attic-mounted equipment require more time and reach the upper range. Commercial systems are quoted individually based on square footage and system complexity.
Several factors affect where your home falls in this range. The number of duct runs is the primary variable - we count supply and return lines, not just rooms. Attic or crawlspace access for the air handler adds time compared to basement or closet locations. Heavy construction debris or pest intrusion requires additional agitation passes. Multiple HVAC zones with separate plenums are priced as separate systems because each requires its own negative-pressure setup.
The most reliable way to avoid overpaying is to reject any quote that won’t put the full scope and price in writing before work starts. The $79-$149 coupon offers common in mailers and online ads typically cover only a superficial register cleaning, with substantial upsells once the technician is in your home. CleanRun’s Haven Standard Clause 1 prohibits this practice - the price we write is the price you pay, with no exceptions.
Every estimate includes the full cleaning scope, the documented photo record, and the 365-Day Done Right Promise at no additional charge. We also offer a Free Second Opinion on any written estimate from another company - bring their quote and we’ll put our number next to it in writing.

Frequently Asked Questions - Air Duct Cleaning in Leesburg
Air duct cleaning is the mechanical removal of accumulated dust, debris, and contaminants from the interior surfaces of your HVAC duct network, including supply ducts, return ducts, the plenum (the central distribution box), and registers. The process uses negative-pressure vacuums and agitation tools to dislodge and extract material that has settled over years of system operation. In Leesburg homes, we commonly remove construction debris from newer builds, settled dust and pollen from seasonal cycles, pet dander, and in some cases mold or mildew growth associated with humidity.
A typical residential full-system cleaning takes 3-5 hours depending on system size, duct configuration, and debris levels. Smaller single-level homes in Leesburg may be completed in under 3 hours, while larger properties in Lansdowne or Woodlands with 20+ duct runs and multiple zones can extend to 6 hours. Commercial systems require individual scheduling estimates. We do not rush - incomplete cleaning leaves debris that recontaminates the system within months. Call (571) 487-7204 to schedule a specific time estimate for your home.
Residential air duct cleaning in Leesburg typically costs $380-$720 for a complete system, with the final price determined by duct run count, system accessibility, and whether multiple zones require separate treatment. Video inspection alone runs $180-$240. CleanRun delivers a written flat price before any work begins - Haven Standard Clause 1 - with no per-vent add-ons or equipment surcharges.

Yes. We clean ductwork connected to all major HVAC and air quality brands, with specific experience on Aprilaire media air cleaners, dehumidifiers, and ventilation systems; Abatement Technologies HEPA and containment equipment; and Guardsman UV treatment systems installed in ductwork. Our technicians understand how each manufacturer’s components affect cleaning access and take precautions to protect integrated equipment. Whether you have these brands or any other make, we can clean your ducts without voiding warranties.
We do not advertise same-day or emergency dispatch for duct cleaning because it is a scheduled maintenance service, not an urgent repair. However, we maintain flexibility for time-sensitive situations including real estate transactions, post-renovation move-ins, and health-related concerns - call (571) 487-7204 and we’ll accommodate your timeline if at all possible. All calls are answered by a live person, 24/7, who can schedule your appointment or connect you with our team.
Every job is backed by the 365-Day Done Right Promise in writing - if the work is not right, we make it right, with no manager approval required to honor the commitment. This is Haven Standard Clause 5, applied to every customer, not a discretionary policy. The promise covers workmanship and completeness; it does not cover new debris accumulation from ongoing use, construction, or filter neglect, which is why we include the photo record as baseline documentation.
Clear a path to your HVAC equipment and ensure we can access all registers and return grilles - move furniture or objects blocking these openings. We’ll need to run vacuum hoses from our truck to your system, so driveway or street access is helpful. Pets should be secured in a separate area during the 3-5 hour service. You do not need to clean or vacuum beforehand - our containment system handles debris release. We’ll confirm these details when scheduling and remind you by text the day before.
