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.

Call (737) 259-5752 for a free estimate with a written number.
How Rotobrush Products Fail - and How We Fix Them
- Rotobrush BrushBeast and aiR+ XP models suffer premature blower motor fatigue in Round Rock’s hard-water zones. The calcium buildup from local municipal supply accelerates bearing wear, which drops airflow through the duct run (the metal pathway that carries conditioned air to each room) below the threshold needed for effective UV light distribution. We pull the motor, document the scale pattern with photos, and replace with an OEM-spec unit or a verified aftermarket equivalent that meets Rotobrush’s CFM requirements. Haven Standard Clause 1 applies: written price before work starts.
- The aiR+ XP’s integrated HEPA module develops seal degradation after 18-24 months in Texas heat. The gasket material between the filter housing and the main chassis hardens in attic installations common in Teravista and Stone Oak Ranch builds, bypassing unfiltered air. We replace the seal set with manufacturer-matched silicone-rated gaskets and pressure-test the assembly before reinstallation. The camera goes in first. Then we talk.
- Rotobrush negative-air machines lose vacuum efficiency when the flex-duct collection hose develops micro-tears. These tears are invisible to a homeowner but show up immediately on our manometer readings as a pressure drop across the plenum (the central distribution box where all duct runs connect). We replace with Abatement Technologies hose rated for the same static pressure, or source OEM Rotobrush flex if the customer prefers.
- BrushBeast contactors fail closed in high-humidity crawl spaces, leaving the sanitizing fogger pressurized when it should be off. This is a genuine safety issue - a pressurized chemical reservoir with no active airflow creates a leak risk. Our techs test the contactor with a multimeter, replace with a Honeywell-compatible 24V relay if OEM stock is delayed, and verify shutoff sequencing three times before signing off.
- Older Rotobrush RBL series units show oxidized UV lamp sockets after cedar pollen season in Round Rock. The conductive grease degrades faster here than in drier climates, causing intermittent lamp ignition that owners mistake for bulb failure. We clean the socket with electrical contact cleaner, apply fresh conductive compound, and only then quote a replacement lamp if the issue persists. Most “bad bulbs” we see are actually bad connections.
Our Rotobrush Air Quality & Sanitizing Process

- 1
Camera inspection of every main trunk line. Tomas Reyes runs the scope himself on Rotobrush jobs - he grew up in Queens apartment buildings with ancient ductwork, and he doesn’t quote from a hallway guess. You see what we see before any price is written.
- 2
Written scope and price delivered on site. Haven Standard Clause 1: the price is fixed per system, not per vent, and it’s in your hand before a tool touches your equipment.
- 3
Parts decision with documentation. We note whether we’re installing OEM Rotobrush components or verified aftermarket equivalents from Nikro, Abatement Technologies, or Guardsman - your choice, your record.
- 4
Service execution with photo documentation. Every duct run, before and after. Mold treatment, bacteria sanitizing, odor removal, or UV installation - the photo record shows what happened inside your system.
- 5
Post-service testing and sign-off. We verify airflow, pressure, and lamp function against manufacturer spec, then deliver your job record including photos, scope, and the 365-Day Done Right Promise in writing.
- 6
Cleanup and departure. Uniformed, background-checked crew under Haven Standard Clause 3: Verified Crews. You know who was in your home.

Why Round Rock Homeowners Call CleanRun Duct Repair & Cleaning for Rotobrush Work

We’ve served Round Rock since 2013, including repeated jobs in Stone Oak Ranch and Teravista where cedar pollen and construction dust test equipment harder than most climates. Our 365-Day Done Right Promise is backed in writing on every job - not a policy subject to manager approval, but a guarantee. Technicians are background-checked, uniformed, and identified by name before arrival under Haven Standard Clause 3. We also service Lennox, Trane, and Carrier air quality systems, so if your Rotobrush unit is integrated with another brand’s HVAC, we don’t need a second truck roll. The photo record from every visit is yours to keep, and every call is answered by a live person. No exceptions.
FAQs
No. Rotobrush warranties cover manufacturing defects in the equipment itself, not environmental conditions inside your ductwork or the service work performed by an independent provider. As an independent Rotobrush service provider, CleanRun documents our work with photos and a written scope so you have a separate record of what was done and when. Call (737) 259-5752 for a free estimate.
Both can be reliable if properly specified. We stock OEM filters, lamps, and seals for current Rotobrush series, and we source verified aftermarket components from Nikro, Abatement Technologies, and Guardsman when OEM lead times stretch past what’s reasonable. We note which option you chose in your written job record, so there’s no mystery later. Call (737) 259-5752 for a free estimate.
The photo record shows visible contamination before and after, and we test airflow and pressure post-service against manufacturer specifications. For mold treatments, we can arrange third-party lab verification at your request - an additional cost we’ll quote in writing upfront if you want it. Haven Standard Clause 1: no surprises. Call (737) 259-5752 for a free estimate.
Yes, with the caveat that our work doesn’t extend or transfer Rotobrush’s original warranty. We use warranty-safe practices - no drilling, no electrical modifications outside spec, no chemical exposure to components that would void coverage. If your unit is near warranty expiration, we’ll note that in our assessment so you can make an informed repair-vs-replace decision. Call (737) 259-5752 for a free estimate.
Every 18-24 months for standard residential use, sooner if you have pets, recent construction, or allergy-sensitive occupants. Round Rock’s cedar pollen season and caliche dust from new development in areas like Paloma Lake accelerate filter loading and UV lamp degradation. We inspect and advise based on what the camera shows, not a calendar. Call (737) 259-5752 for a free estimate.
