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.

AfterRotobrush Air Duct Cleaning in Fairfax: What to Know First
CleanRun Duct Repair & Cleaning provides independent Rotobrush air duct cleaning in Fairfax, typically completed in a single scheduled visit with a written price delivered before any work begins. Most residential systems in Fairfax run between $420 and $780 for a full cleaning, depending on the Rotobrush equipment configuration and how many duct runs serve the home. We’re not affiliated with Rotobrush; we service their equipment as an independent Rotobrush service provider, which means we source parts based on what actually works, not what a manufacturer catalog dictates.
This page is for Fairfax homeowners who already own Rotobrush-branded air duct cleaning equipment, or who had their ducts cleaned by a Rotobrush operator and need follow-up work, repair, or a second opinion on whether the job was done right. If you’re seeing dust blowback, weak suction at the register, or uneven cleaning results from a previous service, call (571) 526-0015. We’ll put a written estimate next to any competitor’s quote, free of charge.
How Rotobrush Products Fail - and How We Fix Them
- Beast Series brush motor seizure from drywall dust packing. The Beast’s high-torque motor pulls hard, but in Fairfax’s older split-levels near the Mosaic District, decades of settled drywall compound and fiberglass liner debris can pack the brush head until the motor overheats and the thermal cutout trips. We disassemble the brush carriage, clean the armature housing with compressed air and a non-residue solvent, and replace the motor only if the windings test above 15% resistance variance. Most times it’s a $180 cleaning, not a $340 motor swap.
- Air+ and Air+ XP vacuum blower impeller cracks from silica grit. Northern Virginia’s clay-heavy soil produces fine silica that lodges in ductwork; when it hits the Air+ series’ plastic impeller at speed, stress fractures develop. The OEM impeller runs $90-$140, but we’ve found the aftermarket aluminum impeller from Guardsman outlasts it 3:1 in silica environments. We stock both and explain the trade-off in writing before installing either.
- Brush cable binding in the RotoVent 2 dryer vent attachment. The RotoVent 2’s flexible cable is rated for 25 feet, but Fairfax townhomes with roof-vented dryers often need 35+ feet of reach. The cable binds in the sheath, kinks, and eventually frays. We replace with a custom-length Nikro cable assembly, matched to the actual vent run we measure with a borescope. Haven Standard Clause 1: the written price includes the measured length, not a guess.
- Control board moisture damage in humid crawlspace storage. Rotobrush units stored in Fairfax’s frequent damp crawlspaces, especially in the Wakefield Chapel area where the water table sits high, develop corrosion on the 24V control board terminals. We clean the board with contact cleaner, test each relay, and only replace if the solder joints show pitting. A $65 board cleaning beats a $290 replacement when the traces are still sound.
- HEPA filter collapse from overfilling. The factory HEPA on the Beast and Air+ series is rated for 99.97% at 0.3 microns, but operators who skip the pre-filter cleanout force the pleats to load beyond design. The filter media tears, bypassing dirty air back into the home. We install Abatement Technologies replacement HEPA cartridges with deeper pleat spacing, and we photograph the loaded filter before removal so the customer sees why it failed.
Our Rotobrush Air Duct Cleaning Process
- 1
Video inspection before quote. We run a camera through every duct run, including the plenum (the main distribution box where heated or cooled air mixes before splitting to rooms). The camera goes in first. Then we talk. Tomas Reyes started this practice in 2013 after finding a competitor had “cleaned” a Fairfax home without touching a completely blocked return trunk.
- 2
Written scope and price. Haven Standard Clause 1: one flat price per system, agreed in writing, before any panel comes off. No per-vent pricing, no add-ons after arrival.
- 3
OEM or quality aftermarket parts selection. Based on the inspection, we specify Rotobrush OEM parts or verified equivalents from Nikro, Guardsman, or Abatement Technologies. The customer sees the part number and source before we order.
- 4
Negative-pressure extraction with brush agitation. We connect the Rotobrush unit or our backup Nikro system to each duct run, maintaining continuous suction while the rotating brush dislodges debris. The plenum and each register boot are photographed before and after.
- 5
Post-cleaning airflow test and photo record delivery. We measure static pressure at the air handler and deliver the full Documented Photo Record, including every before-and-after image, as a standard job deliverable. The 365-Day Done Right Promise is included in writing.

Why Fairfax Homeowners Call CleanRun Duct Repair & Cleaning for Rotobrush Work
We’ve served 52,000+ homes since 2013, every one with a written price before work started and a photo record when we left. The 365-Day Done Right Promise means if the work isn’t right, we make it right, backed in writing on every job, not just stated in marketing copy.
Our technicians are background-checked, uniformed, and identified by name before arrival, operating under Haven Standard Clause 3: Verified Crews. They carry Rotobrush, Nikro, and Abatement Technologies equipment, with backup knowledge of Lennox, Trane, and Carrier systems when the ductwork connects to those air handlers.
Fairfax’s housing stock varies sharply, from 1960s rambler conversions near Fairfax Circle to new construction in Fair Lakes with flex-duct systems that fail differently than rigid metal. We’ve cleaned both. Tomas Reyes, who grew up maintaining aging HVAC in Queens apartment buildings before building this crew, trains every technician to photograph the register boot before quoting and to explain what the picture shows in plain language.
FAQs
No. Routine duct cleaning does not void your HVAC manufacturer’s warranty, provided the work is performed without damaging the ductwork or air handler components. As an independent Rotobrush service provider, we document our process with photos to prove no damage occurred. If you’ve been told otherwise by an HVAC company selling new equipment, bring us their written statement; we’ll review it free under our Second Opinion policy. Call (571) 526-0015.
Request the photo record. A legitimate Rotobrush cleaning produces timestamped before-and-after images of each duct run, the plenum, and the register boots. If your previous provider delivered none, or only showed you a vacuum canister of debris with no location data, the ducts may not have been fully cleaned. We include the Documented Photo Record as a standard deliverable on every Fairfax job, and we review it with you before final payment.
Repair if the frame and vacuum blower housing are sound and the repair costs less than 40% of replacement. Replace if the unit has repeated electrical failures or if you need capabilities the Rotobrush line doesn’t offer, such as true negative-pressure extraction for commercial systems. We’ll assess your machine honestly; we sell no equipment, so our recommendation carries no commission bias.
Most single-system homes take 3 to 5 hours, including setup, the full cleaning, and the post-job photo review with the customer. Larger homes in the Fairfax Station area with multiple zones, or properties with difficult attic access, may run longer. We schedule by the job, not by the hour, so the crew doesn’t rush to hit a quota.
Yes, and we frequently do. We find improper brush sizing, missed return duct runs, and filters installed backwards on about one in four second-opinion calls in Fairfax. We photograph everything before touching it, quote the correction in writing, and apply the full Haven Standard including the 365-Day Done Right Promise. Call (571) 526-0015 to schedule.
