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 San Antonio: What to Know First
CleanRun Duct Repair & Cleaning provides independent Rotobrush air duct cleaning in San Antonio with written prices delivered before any work starts and a documented photo record of every duct run. Most residential Rotobrush cleanings are completed in a single scheduled visit, with your photo record delivered before the crew leaves. We are not affiliated with or authorized by Rotobrush.
This page is for San Antonio homeowners who own Rotobrush equipment and need their supply ducts, return ducts, or full system cleaned by technicians who understand how these machines interact with the flex duct and hard duct common in Alamo Heights, Stone Oak, and Helotes tract builds. Call (726) 600-7155 for a free estimate with a written price.
How Rotobrush Products Fail - and How We Fix Them
- Beast Series brush motor burnout from reverse torque. The Beast 8.5 and Beast 10.5 push-pull motors can overheat when the cable binds in a collapsed flex duct run, a condition we see regularly in Stone Oak homes built 2015-2020 with sagging flex at the plenum inlet. Our fix: we scope the run first with a camera, identify the collapse point, then relieve the mechanical load before engaging the brush. If the motor has already burned, we source OEM-spec replacement motors or verified aftermarket equivalents with matching torque curves.
- Air+ HEPA vacuum seal degradation in high-humidity cycles. San Antonio’s spring humidity spikes and summer monsoon patterns stress the Air+ series HEPA gasket seals, which can crack and leak negative pressure. The symptom is visible dust blowback at the register during operation, not poor suction at the machine. We replace seals with OEM-grade silicone gaskets rated for 90+ percent humidity, and we test seal integrity with a manometer before the brush enters the duct.
- Brush cable kinking in the Roto-Vision camera line. The Roto-Vision’s integrated camera cable is thinner-gauge than the Beast cable and prone to tight-radius kinking at the first elbow of a 6-inch duct run. Once kinked, the camera feed ghosts or drops. Our fix: we stock replacement camera heads and cable assemblies, and we route the inspection camera separately from the brush cable on jobs where the duct geometry is tight.
- Removable pod latch fatigue on older Air+ units. The polycarbonate latch tabs on pre-2019 Air+ pods crystallize and snap after repeated heat cycling in unconditioned San Antonio attics. A pod that won’t seal is a machine that won’t maintain negative pressure. We carry machined aluminum replacement latches that outlast the OEM plastic, or we can source factory pods when the owner prefers.
- Beast cable drive gear stripping under load. The brass drive gear in early Beast 8.5 units strips teeth when the brush head jams on a heavy debris mat, typically at the plenum inlet where construction dust and pet hair accumulate. Our fix: we extract the brush manually, clean the obstruction with a separate negative-pressure tool, then replace the gear with a hardened steel aftermarket unit or factory brass depending on the customer’s preference and warranty status.
Our Rotobrush Air Duct Cleaning Process
- 1
Camera inspection first. The camera goes in first. Then we talk. We scope every duct run to document debris type, duct condition, and any mechanical obstruction before writing a price.
- 2
Written price delivered. Haven Standard Clause 1: the price is written and agreed before any panel comes off. No exceptions. The scope specifies which runs will be cleaned, which parts if any will be replaced, and the total.
- 3
Parts decision with the customer. If a Rotobrush component needs replacement, we present OEM and quality aftermarket options with the real warranty implications of each. The customer chooses; we document the choice in writing.
- 4
Cleaning and repair with photo documentation. Every duct run is photographed before and after. The Rotobrush machine is operated at the manufacturer-specified feed rate, with negative-pressure extraction at the register to prevent blowback into the living space.
- 5
Post-job test and photo record delivery. We verify airflow at the register with an anemometer, deliver the photo record to the customer, and activate the 365-Day Done Right Promise in writing.

Why San Antonio Homeowners Call CleanRun Duct Cleaning San Antonio for Rotobrush Work
We have cleaned Rotobrush equipment in San Antonio since 2013, and we have learned that these machines reward technicians who read the manual and punish those who don’t. Tomas Reyes, our owner, trained in HVAC systems technology at Queensborough Community College and spent years in hands-on ductwork before bringing that method to San Antonio. His crew has logged thousands of hours on jobs including tract homes near Stone Oak where flex duct collapses and dust accumulation are textbook examples of what we document.
Our technicians are background-checked, uniformed, and identified by name before arrival, per Haven Standard Clause 3: Verified Crews. We also service Lennox, Trane, and Carrier systems, so we understand how Rotobrush equipment integrates with the full HVAC ecosystem rather than treating it in isolation. Every job concludes with a Documented Photo Record and the 365-Day Done Right Promise, both delivered in writing.
FAQs
No. As an independent Rotobrush service provider, we use manufacturer-specified practices and parts that do not trigger warranty exclusion. We document our methods and parts on every job record so you have evidence of proper service if a warranty claim arises later. If you have concerns about a specific component, bring your warranty paperwork and we will review it before writing the price. Call (726) 600-7155 to schedule.
The camera shows the difference. If the brush spins freely, the vacuum holds negative pressure, and the duct run is clear, you need cleaning only. If the motor labors, the seal leaks, or the cable binds, you need repair. We scope first and show you the footage before quoting either. Call (726) 600-7155 for a free inspection with written findings.
Not always. OEM parts carry the manufacturer warranty and are the conservative choice for newer machines. For certain wear items, like the machined aluminum pod latches we stock, quality aftermarket parts outlast factory equivalents at lower cost. We present both options with the real trade-offs and let you decide. The choice is documented in your job record. Call (726) 600-7155 to discuss your specific machine.
A standard residential full-system cleaning takes three to five hours, depending on the number of duct runs and whether we find collapsed flex or heavy debris mats that require additional extraction time. Commercial systems scale accordingly. We schedule by the job, not by the hour, so the crew stays until the scope is complete and the photo record is delivered. Call (726) 600-7155 to book a slot.
Bring us the written estimate. Haven Standard Clause 2: Free Second Opinion. We will put our written price next to theirs, line by line, and explain where the scope differs. In our experience, low quotes often omit the camera inspection, exclude the photo record, or quote per-vent pricing that balloons once the truck arrives. Our price is one flat price per system, agreed before work starts. Call (726) 600-7155 with your estimate in hand.
