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.

How Rotobrush Products Fail - and How We Fix Them
- Rotobrush aiR+ series with stuck or intermittent brush motor. The aiR+ uses a brushed DC motor in the whip assembly that seizes when Gulf Coast humidity wicks into the bearing housing after filter bypass events. We see this in Energy Corridor and Memorial area homes where the unit sits in a hot attic plenum, the box that distributes conditioned air to each duct run. Our fix: disassemble the whip head, replace the motor with an OEM Rotobrush part or a verified aftermarket equivalent rated for 85% RH continuous operation, and photograph the internal debris load that caused the overload.
- Rotobrush Beast series with collapsed flex-duct at the sanitizing injection point. The Beast’s higher static pressure, the resistance the fan works against, can blow out aging flex-duct at the Y-fitting where sanitizing solution is introduced. This is common in Houston homes built 2015-2019 with gray non-barrier flex. We replace the damaged section with R-8 insulated flex, secure with Panduit straps rather than tape, and re-balance the injection rate so the Beast doesn’t over-pressurize on the next cycle.
- Rotobrush BrushBeast with clogged HEPA final filter and false “clean” readings. The BrushBeast’s HEPA stage loads fast in Houston’s pollen-heavy spring; when saturated, the unit recirculates fine particulate instead of capturing it. Owners think their ducts are clean because the machine ran, but the post-job photo record shows otherwise. We replace the HEPA with a genuine Abatement Technologies HEPA or OEM Rotobrush element, log the pressure differential across the filter before and after, and show the customer both numbers in writing.
- Rotobrush aiR+ with cracked polycarbonate debris canister. The aiR+ canister develops stress fractures near the latch points after repeated heat cycling in Houston attics. A cracked canister leaks sanitized debris and moisture back into the plenum, defeating the entire purpose. We source the updated Rotobrush canister with the reinforced rib design, or a Guardsman replacement rated for the same 2.5-gallon capacity, and pressure-test the seal before the job continues.
- Rotobrush UV light kits with failed ballast or degraded quartz sleeve. Rotobrush’s add-on UV-C systems, the ones that kill mold and bacteria in the plenum, suffer ballast failure when Houston’s voltage fluctuates during summer grid strain. The quartz sleeve that protects the lamp also etches from years of humid airflow, dropping UV output below effective levels. We test actual UV intensity with a radiometer, replace the ballast with a Honeywell or Aprilaire equivalent if Rotobrush OEM is backordered, and only reinstall a lamp that reads above 100 µW/cm² at one meter.
Our Rotobrush Air Quality & Sanitizing Process

- 1
Written estimate delivered on arrival. We inspect the Rotobrush unit model, serial, and installed configuration, then deliver a written price before any panel comes off. Haven Standard Clause 1: no exceptions.
- 2
Photo-documented internal inspection. Our technician runs a borescope camera through every duct run, the individual branch from plenum to register, and saves the images to your job record. The photo goes first. The pitch comes later, if it’s warranted.
- 3
Component diagnosis with OEM vs. aftermarket recommendation. We identify the failed part, check Rotobrush OEM availability, and present a quality aftermarket option from Nikro, Abatement Technologies, or Guardsman when lead times or pricing favor it. You choose; we document the choice in writing.
- 4
Sanitizing or repair with negative-pressure containment. For mold or bacteria treatment, we set up negative-pressure extraction, the practice of pulling air out of the work zone so contaminants don’t migrate, apply EPA-registered sanitizer to the full duct run, and run the Rotobrush unit to mechanical agitation spec.
- 5
Post-job testing and photo record delivery. We re-camera the duct run, measure airflow at the register with a calibrated anemometer, and deliver before-and-after photos plus the written scope as standard deliverables.
- 6
365-Day Done Right Promise activation. The written guarantee goes into your file. If the odor returns, the mold recurs, or the UV reading drops, we make it right.

| Rotobrush aiR+ / Beast / BrushBeast sanitizing (whole system) | $380-$580 | Number of duct runs, accessibility of plenum, debris load requiring extra agitation time |
| Mold treatment with EPA-registered sanitizer | $480-$740 | Visible mold extent, need for physical removal vs. chemical treatment only, post-treatment lab verification if requested |
| UV-C light installation (Rotobrush-compatible) | $320-$520 per lamp | Plenum material (sheet metal vs. fiberglass), electrical routing distance, single vs. dual-lamp configuration |

Why Houston Homeowners Call CleanRun Duct Repair & Cleaning for Rotobrush Work

We’ve been in Houston since 2013, and in that time we’ve learned that Gulf Coast humidity turns a mildly dusty duct into a debris problem faster than most homeowners expect. Tomas Reyes, our owner, picked up his HVAC fundamentals at Bronx Community College and spent years doing hands-on duct work across the northeast before relocating the operation here. He’s put in the hours across neighborhoods like the Energy Corridor, where older commercial builds and residential retrofits gave him a working education in what Rotobrush equipment actually faces in this climate.
Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews. We also service Lennox, Trane, and Carrier systems, so if your Rotobrush unit is integrated with a mixed-brand HVAC setup, we don’t need to call in another contractor. Every job starts with a written price and ends with a photo record you can keep. The 365-Day Done Right Promise is backed in writing, not just stated in marketing copy.
FAQs
No, independent service does not void the Rotobrush equipment warranty, provided the work is performed without physical modification to the unit’s core housing or electrical. As an independent Rotobrush service provider, CleanRun uses OEM or equivalent parts and documents everything in writing so warranty claims remain straightforward if you ever need them. Call (346) 251-8919 if you want us to review your warranty terms before scheduling.
You receive a Documented Photo Record of every duct run, before and after, as a standard deliverable on every CleanRun visit. We also measure and log airflow at the register with a calibrated instrument, not guesswork. If the photo doesn’t show a visible change and the airflow number hasn’t moved, we don’t consider the job complete.
Repair makes sense when the failure is isolated to a replaceable component, the brush motor, HEPA filter, or UV ballast, and the unit chassis is intact. Replacement is the better call when the polycarbonate housing has heat-degraded, common in Houston attics after eight to ten years, or when repair parts approach 60% of replacement cost. We give you both numbers in writing and let you decide.
Rotobrush aiR+ and Beast series parts are generally available within two to four business days through our distributors. For discontinued lines, we maintain cross-references to Nikro, Abatement Technologies, and Guardsman equivalents that fit without modification. We never start a job until we confirm parts in hand.
Most Houston homes benefit from full-system sanitizing every three to five years, but the interval compresses to two to three years if you have pets, run the fan continuously, or live near construction or major roadways where fine particulate loads are higher. The inspection photo record tells the real story; we don’t recommend service the camera doesn’t support.
