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 Duct Repair & Sealing in Lewisville: What to Know First
We provide independent Rotobrush duct repair and sealing in Lewisville, with most jobs completed in a single scheduled visit and written pricing delivered before any work begins. A typical Rotobrush repair runs $280-$620 depending on whether we’re sealing accessible joints or replacing damaged flex duct runs behind drywall. Every job ends with a documented photo record of every duct run we touched.
This page is for Lewisville homeowners who already own a Rotobrush air duct cleaning system or whose HVAC installer specified Rotobrush-compatible ductwork, and who need actual repair work - not a sales pitch for new equipment. If your Rotobrush unit is pulling weak suction, blowing dust from seams, or making noise at the plenum connection, the problem is usually in the duct path, not the machine. Call (940) 240-8552 for a free written estimate.
How Rotobrush Products Fail - and How We Fix Them
- Rotobrush BrushBeast and BrushBeast 2.0 - loose plenum collar connections. The 16-inch diameter collar on BrushBeast units mates to a sheet-metal plenum with a compression band. In Lewisville’s clay-heavy soil, slab movement cracks the mastic seal between collar and plenum over 3-5 years. We remove the collar, re-seat with fresh mastic, and add a mechanical draw band under Haven Standard Clause 4: Work You Can See.
- Rotobrush aiR+ XP - cracked flex duct at the first elbow. The aiR+ XP’s higher static pressure (2.1 inches water column) exposes weak points in original flex duct, especially the 90-degree elbow off the main trunk in attic runs. We see this constantly in Castle Hills homes built 2015-2019, where installers used R-6 flex instead of R-8. Our fix: cut back to solid trunk, install a metal turning vane, and transition to new R-8 flex with a proper support strap every 4 feet.
- Rotobrush DuctMaster - separated inner liner from insulation jacket. The DuctMaster’s reverse-bristle design creates pulsation that vibrates the duct wall. Over time the inner polyethylene liner detaches from the fiberglass insulation, creating a ballooned section that traps debris and restricts airflow. We don’t patch this - we replace the run and add an inline damper to reduce pulsation at the source.
- Rotobrush Hurricane - stripped drive-cable housing threads. The Hurricane’s 450-rpm cable housing screws into a cast-aluminum junction block at the duct entry point. Cross-threading during homeowner maintenance is common, and the OEM block is backordered 2-3 weeks. We keep quality aftermarket junction blocks in stock, machine-faced to OEM spec, and document the swap with before-and-after photos of the thread engagement.
- Rotobrush aiR+ and legacy BEAST models - failed boot-to-register seals. The rectangular duct boot where flex meets the wall register dries out in Lewisville’s summer attic heat, which regularly exceeds 140°F. The boot cracks at the corners, dumping conditioned air into the joist bay. We cut out the old boot, install a galvanized adjustable boot with a built-in gasket flange, and seal with mastic - not foil tape, which fails in 18 months in this climate.
Our Rotobrush Duct Repair & Sealing Process
- 1
Camera inspection with written scope. We run a borescope through every duct run connected to the Rotobrush unit, photograph the failure point, and deliver a written scope with line-item pricing before any panel comes off.
- 2
Parts verification. For BrushBeast and Hurricane models, we check whether OEM parts are in regional stock or if a quality aftermarket equivalent meets manufacturer spec. We note the source on the written estimate - Haven Standard Clause 1 requires this transparency.
- 3
Repair execution with photo documentation. Every cut, every seal, every replacement section is photographed. The camera shows a 3-inch debris build-up at the first elbow, or the cracked boot corner, or the draw band torque spec - whatever matters to prove the work happened.
- 4
Static-pressure test and airflow verification. We test the repaired system at the Rotobrush service port with a digital manometer, comparing pre- and post-repair readings. The numbers go on the job record.
- 5
Cleanup, photo record delivery, and written guarantee. The homeowner receives all photos and the 365-Day Done Right Promise in writing before we leave. Here’s the before photo. Now let’s talk about what happens next.

Why Lewisville Homeowners Call CleanRun Air Duct Cleaning Lewisville for Rotobrush Work
We’ve been running jobs in Lewisville since 2013, including plenty of older homes near Castle Hills where the flex duct tends to sag and accumulate debris in ways that don’t show up until you put a camera inside. Tomas Reyes, our owner, picked up his HVAC fundamentals at Manhattan’s Apex Technical School and has spent two-plus decades working inside ductwork across North Texas.
Our technicians are background-checked, uniformed, and identified by name before arrival - Haven Standard Clause 3: Verified Crews. We also service Lennox, Trane, and Carrier systems, so if your Rotobrush unit connects to equipment from another brand, we don’t need a second contractor. The 365-Day Done Right Promise, the documented photo record, and the written price before work starts apply to every job, no exceptions.
FAQs
No - duct repairs performed by an independent service provider do not void the Rotobrush unit warranty, which covers the machine itself, not the attached ductwork. We use manufacturer-spec or equivalent parts and document everything, so if a warranty claim ever arises on the unit, the repair record supports rather than complicates it. Call (940) 240-8552 if you need help understanding what’s covered.
OEM BrushBeast and Hurricane parts ship from Rotobrush’s Dallas-area warehouse in 2-4 business days, but backorders on cast-aluminum junction blocks and certain collar assemblies can stretch to 2-3 weeks. We stock quality aftermarket equivalents for common failures and will note on your written estimate whether we’re using OEM or aftermarket - Haven Standard Clause 1 requires this. Most jobs don’t wait on parts.
Repair is the right call when the failure is isolated to one or two runs, the main trunk is intact, and the Rotobrush unit itself is under 10 years old. We recommend replacement when we find three or more failed joints, visible corrosion on galvanized trunk lines, or flex duct installed before 2010 that’s brittle throughout. We’ll show you the camera footage and give you both numbers in writing.
We photograph the inside of every duct run before and after, and we test static pressure with a digital manometer at the Rotobrush service port. The photos and pressure readings are delivered as part of your standard job record - not available on request, included automatically. If the numbers don’t move or the photos don’t show new mastic, the work didn’t happen. Our documentation makes that impossible.
Yes - Rotobrush duct cleaning systems interface with ductwork, not the air handler brand. We service Lennox, Trane, and Carrier equipment regularly and understand how each manufacturer’s static-pressure spec interacts with Rotobrush operation. The repair approach changes slightly - Carrier Infinity systems, for example, are more sensitive to duct leakage - and we account for this in our scope and pricing.
