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.
Rotobrush Air Quality & Sanitizing in Leesburg: What to Know First
CleanRun Duct Repair & Cleaning provides independent Rotobrush air quality and sanitizing service in Leesburg, typically scheduled within a week and completed in a single visit. A written price is delivered before any work starts, every time, under Haven Standard Clause 1. Most Leesburg homeowners with Rotobrush systems call us for mold treatment, bacteria sanitizing, odor removal, or UV light installation after noticing persistent mustiness near registers or elevated allergy symptoms that standard filter changes don’t resolve. If you own a Rotobrush air handler, duct-mounted purifier, or whole-house ventilator and need sanitizing work done right, call (571) 487-7204 for a free estimate. The camera goes in before the quote comes out.
How Rotobrush Products Fail - and How We Fix Them
- Rotobrush Beast series brush motor seal degradation. The Beast’s aggressive brush action generates fine particulate that settles in the plenum, the main distribution box where all duct runs connect. When the motor seal wears, that debris recirculates instead of being captured. We replace the seal with OEM-spec fluorocarbon gaskets and follow with negative-pressure extraction, a suction process that pulls loosened debris out of the system rather than pushing it deeper.
- Rotobrush BrushBeast and BrushBeast Lite UV lamp socket corrosion. These units mount UV-C lamps in high-humidity return paths, and Loudoun County’s freeze-thaw cycles drive moisture into sockets through thermal expansion gaps. Corroded sockets read as “lamp failure” on the control board when the lamp itself is fine. We test with a multimeter at the socket, replace only what’s actually failed, and install a dielectric grease barrier rated for the temperature swing Leesburg sees from January to July.
- Rotobrush aiR+ XP and aiR+ XP Plus HEPA media frame warping. The plastic frame on these compact units distorts when subjected to attic temperatures above 140°F, common in Leesburg’s unvented Cape Cod and colonial attic builds. Warped frames bypass unfiltered air. We measure frame squareness with a digital caliper, replace with OEM or Guardsman-certified aftermarket frames that carry the same temperature rating, and photograph the seal integrity before and after.
- Rotobrush DuctMaster and DuctMaster Pro odor retention in polymer brush cores. The flexible polymer brushes absorb organic odors from previous jobs, particularly in homes with rodent activity or previous water intrusion. On sanitizing calls, we replace the brush core entirely rather than attempting chemical deodorization, then treat the duct run with Abatement Technologies’ EPA-registered sanitizer applied through a fogging manifold at the plenum.
- Rotobrush HEPA filtration retrofit mounting bracket fatigue. Aftermarket HEPA upgrades on older Rotobrush portable units rely on stamped steel brackets that crack at the bend radius after repeated transport in and out of Leesburg’s tighter crawl spaces and basement mechanical rooms. We fabricate replacement brackets from 14-gauge galvanized stock on-site, or source Nikro-compatible heavy-duty mounts when the unit configuration allows.
Our Rotobrush Air Quality & Sanitizing Process

- 1
Visual and camera inspection. We insert a borescope camera into the plenum and first three duct runs to document existing debris, mold staining, or liner deterioration. You see the still frames before we discuss scope.
- 2
Written price delivered. Haven Standard Clause 1: the full scope and flat price per system are written and signed before any panel is removed. No per-vent add-ons, no trip-charge surprises.
- 3
Equipment selection. We specify OEM Rotobrush parts or quality aftermarket equivalents from Guardsman or Nikro, with the source noted on your job record. Warranty-safe practices only; we never use generic parts that void remaining manufacturer coverage.
- 4
Sanitizing execution. Negative-pressure extraction first, then targeted application of EPA-registered sanitizer through a fogging manifold or direct UV lamp installation, depending on the diagnosed issue. Every duct run is photographed after completion.
- 5
Post-work verification. We run the system and capture airflow readings at the supply registers, the visible vents in each room, to confirm restored distribution. The Documented Photo Record, including before/after images and airflow measurements, is delivered as your standard job record.
- 6
365-Day Done Right Promise activation. Your written guarantee is in force from the moment we leave. If the odor, allergen, or microbial issue recurs, we return and make it right.

FAQs
No, if the work is performed with OEM-spec or equivalent parts and EPA-registered sanitizers. As an independent Rotobrush service provider, we document every part source and chemical used on your job record so warranty claims remain valid. Call (571) 487-7204 if you need a specific part number verified before scheduling.
Replacement is our recommendation when the camera shows liner deterioration at seams, motor housing cracks, or control board corrosion that affects safety functions. Sanitizing and targeted repair suffice for surface mold, odor retention, or lamp socket issues. We show you the camera evidence and write both options with prices when both are viable.
OEM guarantees exact fit and preserves warranty coverage on newer units. For out-of-warranty Beast or DuctMaster systems, Guardsman and Nikro aftermarket components often match OEM specifications at lower cost, and we source from trade-recognized suppliers you can verify independently. We note the source on every job record.
Most single-system sanitizing jobs in Leesburg are completed in three to five hours, including inspection, extraction, treatment, and post-work verification. Larger homes with multiple plenums or extensive debris documented on camera may extend to a full day. We confirm the expected duration in writing with your price.
For Leesburg homes with standard suburban dust loads, every three to five years aligns with what we document on camera. Homes with finished basements, visible moisture at the foundation, or occupants with respiratory sensitivities may need more frequent inspection. We don’t sell maintenance contracts; we schedule based on what the last camera pass showed.
