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.
Rotobrush Air Quality & Sanitizing in Marietta: What to Know First
CleanRun Duct Repair & Cleaning provides independent Rotobrush service for air quality and sanitizing in Marietta, with most jobs completed in a single scheduled visit and written pricing delivered before any work begins. A typical Rotobrush sanitizing or odor remediation runs $340-$620 for a whole system, depending on contamination level and whether UV or air purifier installation is included. This page is for homeowners who already own a Rotobrush-branded air handling product and need documented, warranty-safe sanitizing or air quality work - not a sales pitch for equipment they do not have. Call (470) 516-9337 for a free written estimate.
How Rotobrush Products Fail - and How We Fix Them
- Rotobrush BrushBeast and BrushBeast 2.0 - Blower motor seal degradation in humid crawlspaces. The BrushBeast line uses a sealed motor housing that Georgia’s prolonged summer humidity can compromise after 4-6 years, especially in Marietta homes with crawlspace duct runs near the Chattahoochee floodplain. Once the seal fails, condensation enters the housing, breeding mold that recirculates through the supply plenum. We replace the motor seal with an OEM-grade silicone gasket or a verified aftermarket equivalent, then treat the affected duct run with a botanical antimicrobial before reassembly.
- Rotobrush aiR+ XP and aiR+ XP2 - UV lamp socket corrosion from temperature cycling. The aiR+ XP series mounts its UV-C lamp in a plastic socket directly behind the blower wheel. In Marietta, where winter nights drop below freezing and summer afternoons hit the mid-90s, that socket expands and contracts until the contacts oxidize. The lamp flickers or fails entirely, leaving the system without microbial suppression. We install a ceramic-socket retrofit that handles thermal cycling without cracking, then verify UV output with a radiometer before we leave.
- Rotobrush DuctMaster and older DuctMaster Pro - Accumulated biocide residue in the brush head housing. These units were marketed heavily to duct cleaning contractors in the 2010s, and many Marietta homes still have original installations. The brush head’s narrow clearance traps quaternary ammonium compounds from repeated sanitizing treatments, creating a sticky biofilm that off-gasses a chemical odor every time the HVAC cycles. We disassemble the head, media-blast the housing with dry ice pellets, and re-treat with a hydrogen-peroxide-based sanitizer that leaves no residue.
- Rotobrush Guardian Air and Guardian Air QR+ - Ozone plate fouling in pollen-heavy spring seasons. The Guardian Air’s bipolar ionization plates collect the same pine and oak pollen that coats Marietta vehicles every April. When the plates foul, ion output drops and the unit can produce detectable ozone. We remove and ultrasonic-clean the plates, test ion density with a handheld meter, and document the before-and-after readings in the job record.
- Rotobrush Hurricane and Hurricane 3-Stage - HEPA filter seal collapse after wet cleaning attempts. Some owners or inexperienced cleaners have pressure-washed the Hurricane’s filter bank, collapsing the urethane seal that maintains negative pressure. Without that seal, filtered air bypasses the HEPA media and reintroduces captured mold spores. We replace the seal with Abatement Technologies-compatible gasket material and pressure-test the housing to 2.0 inches w.c. before returning it to service.
Our Rotobrush Air Quality & Sanitizing Process

- 1
Written scope and price delivered before arrival. Haven Standard Clause 1: every Rotobrush job starts with a flat price for the whole system, not a per-vent teaser. You approve it in writing before we load the truck.
- 2
Camera inspection of every duct run. We feed a scope through the supply and return lines, photograph the plenum, and note any debris, mold, or mechanical damage. The camera doesn’t lie - and neither does the invoice.
- 3
OEM or verified aftermarket parts selection. For Rotobrush UV sockets, motor seals, and filter gaskets, we stock both OEM and cross-referenced aftermarket from Guardsman and Abatement Technologies. We show you the part, the manufacturer spec sheet, and the warranty implication before installing either.
- 4
Sanitizing treatment matched to the contamination. Mold-positive runs get a hydrogen-peroxide fogging with 30-minute dwell time. Bacterial contamination gets a botanical thymol application. Odor jobs receive activated-carbon pre-treatment before sanitizing. We photograph every stage.
- 5
Post-treatment verification and documentation. We re-scope the treated runs, capture after photos, and deliver the complete photo record as a standard job deliverable. No extra fee. No “trust us.”
- 6
365-Day Done Right Promise activation. The written guarantee goes into effect the moment we leave. If the odor returns, the mold recolonizes, or the UV lamp fails prematurely, we make it right - no manager approval required.

AfterWhat Rotobrush Air Quality & Sanitizing Costs in Marietta
| Service | Typical Range | What Moves the Price |
|---|---|---|
| Whole-system mold treatment (BrushBeast, aiR+ XP) | $380-$580 | Number of contaminated runs, crawlspace access difficulty, HEPA filtration required during work |
| Bacteria sanitizing with botanical application | $320-$460 | System size (tonnage), presence of flex duct vs. rigid metal, pre-existing biofilm buildup |
| Odor removal (Guardian Air, DuctMaster residue) | $340-$520 | Source identification complexity, activated carbon pre-treatment, ozone neutralization needed |
| UV-C lamp installation or socket replacement | $280-$440 | OEM vs. aftermarket socket, single vs. dual-lamp configuration, electrical routing |
| Air purifier add-on (Honeywell, Aprilaire) | $420-$680 | Unit capacity, existing ductwork compatibility, electrical requirements |
These are whole-system prices, not per-vent come-ons. The $79 coupon you saw on the highway billboard covers a shop-vac waved at two registers and a spritz of drugstore disinfectant. We do not offer that service. Every CleanRun price is written, flat, and agreed before work starts. Call (470) 516-9337 for a free estimate - we will put our number next to any competitor’s written quote under our Free Second Opinion policy.
Why Marietta Homeowners Call CleanRun Duct Repair & Cleaning for Rotobrush Work

Tomas Reyes and our crew have handled Rotobrush equipment in Marietta since the DuctMaster Pro was the standard contractor unit, and we have watched the line evolve through the BrushBeast and aiR+ generations. We also service Lennox, Trane, and Carrier air quality components, which matters when your Rotobrush unit is integrated with a mixed-brand system and the failure is at the interface, not the label. Haven Standard Clause 3: Verified Crews means every technician is background-checked, uniformed, and identified by name before arrival. The photo record, the written price, and the 365-Day Done Right Promise are not marketing - they are the only way we have done business since 2013, across 52,000 homes, including hundreds in the neighborhoods near Marietta Square, East Cobb, and the Kennesaw Mountain corridor where Rotobrush installations are concentrated.
FAQs
Rotobrush warranties cover manufacturing defects, not biological contamination or damage from deferred maintenance. If your BrushBeast motor failed because a seal degraded and mold colonized the housing, that is a maintenance issue, not a warranty claim. We document the cause with photos so you have evidence if there is any dispute. Call (470) 516-9337 and we will assess it at no charge.
We stock both. For UV sockets and motor seals, we carry Rotobrush OEM and cross-referenced aftermarket from Guardsman and Abatement Technologies. We show you the part, the price difference, and any warranty implication before installation. As an independent Rotobrush service provider, we are not restricted to factory parts, and we choose based on what holds up in Marietta’s humidity cycles.
You receive a Documented Photo Record of every duct run, before and after, plus post-treatment scope video showing the treated surfaces. For UV installations, we include radiometer readings proving the lamp is emitting at specification. We have held this practice since our first job in 2013 because visible evidence outperforms any verbal assurance.
If the unit is pre-2015 and the brush head housing has accumulated biocide residue, replacement often costs less than repeated disassembly and media-blasting. We will show you the scope footage and give you both numbers in writing - repair and replacement - so you decide based on actual math, not pressure. Our Free Second Opinion applies to replacement quotes from other contractors, too.
Most Rotobrush sanitizing and odor jobs are scheduled within 3-5 business days. Mold treatments requiring containment setup may need 5-7 days to coordinate HEPA filtration equipment. We do not promise same-day dispatch because proper containment and documentation take preparation, and we will not skip steps to hit an artificial deadline. Call (470) 516-9337 for the next available slot.
