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 HVAC Cleaning in Marietta: What to Know First
CleanRun Duct Repair & Cleaning provides independent Rotobrush HVAC cleaning in Marietta, with most jobs completed in a single scheduled visit and a written price delivered before any work begins. We are not affiliated with or authorized by Rotobrush. Typical Rotobrush HVAC cleaning in this market runs $340-$680 for a complete system, depending on whether we’re addressing the evaporator coil, blower assembly, condenser, or full air handler. This page is for Marietta homeowners who already own Rotobrush equipment and need a technician who understands how these systems differ from standard HVAC units, what the common failure points are, and how to clean them without voiding remaining warranty coverage. Call (470) 516-9337 for a free estimate.
How Rotobrush Products Fail - and How We Fix Them
- Beast series brush motor seizure from clay dust buildup. The Rotobrush Beast’s high-torque brush motor sits low in the housing, and Marietta’s Georgia red-clay dust settles into the cooling vents after wet spring months. We’ve pulled Beast units where the motor thermal cutoff tripped three times in one season. We disassemble the brush head, clean the armature with compressed air and contact cleaner, and replace only the motor if the windings test above 3 ohms - otherwise we quote a new OEM motor with the written price before installation.
- BrushBeast belt drive misalignment from flex-duct strain. The BrushBeast uses a belt-and-pulley drive system that slips when homeowners force the unit through tight Marietta crawlspaces with 6-inch flex-duct runs. The belt doesn’t break; it walks off the pulley and grinds the shoulder. We realign the pulley set, replace the belt with a Gates aftermarket equivalent rated for the same RPM, and document the pulley spacing with a photo for the job record.
- Predator series vacuum motor failure from moisture ingestion. The Predator’s two-stage vacuum motor pulls strong, but the moisture separator on early units (pre-2019) cracks at the seam after repeated heat cycles. Marietta’s humidity doesn’t help. We replace the separator with the updated Rotobrush part or a compatible Nikro separator if the OEM is backordered, and we test the new assembly with a water-column manometer to verify seal integrity before the unit goes back into service.
- BrushBeast+ control board corrosion from condensate backflow. The upgraded control board on BrushBeast+ units sits directly below the vacuum chamber, and if the condensate drain line clogs - common in Marietta’s pollen-heavy Aprils - the board takes the hit. We clean the board with isopropyl and a soft brush, test each relay with a multimeter, and replace only the failed components rather than the full board when possible. The customer gets a photo of the corrosion and the relay test readout.
- Beast Lite hose cuff wear at the tool connection. The Beast Lite’s lighter hose uses a plastic cuff that ovalizes after about 200 connection cycles, causing vacuum loss that owners mistake for motor failure. We measure the cuff inner diameter with a caliper; anything over 2.12 inches gets replaced with a reinforced Guardsman cuff that holds its shape. It’s a $28 part that saves a $340 motor replacement, and we show the measurement on the photo record.
Our Rotobrush HVAC Cleaning Process
- 1
Systematic intake and scope. We start with the model name, serial number, and a description of what the unit is doing - or not doing. Tomas Reyes or one of our technicians runs a camera scope through the duct run to document current conditions before touching a tool.
- 2
Written price under Haven Standard Clause 1. We deliver a written price for the exact scope of work before any panel comes off. No per-vent pricing, no add-on surprises. The price covers the full system.
- 3
OEM-vs-aftermarket parts decision. We stock Rotobrush OEM parts where they matter for warranty coverage, and we use quality aftermarket from Nikro, Abatement Technologies, or Guardsman where the specification matches and the price difference benefits the customer without compromising fit or function. We explain the choice in writing.
- 4
Cleaning and repair with documentation. Every duct run, coil face, and blower blade is photographed before and after. The camera doesn’t lie - and neither does the invoice. The customer receives the photo record as a standard deliverable.
- 5
Operational test and airflow verification. We run the unit through its full cycle, measure static pressure across the coil, and verify that the vacuum motor pulls within manufacturer specification. Results go in the written job record.
- 6
365-Day Done Right Promise activation. The written guarantee goes with the customer. If the work is not right, we make it right. Haven Standard Clause 6, in writing, not subject to manager approval.
BeforeAfterWhat Rotobrush HVAC Cleaning Costs in Marietta
| Service | Typical Range | What Moves the Price |
|---|---|---|
| Evaporator coil cleaning (Rotobrush system) | $280-$420 | Coil access (cased vs. uncased), fin condition, need for foaming treatment |
| Blower assembly cleaning and balance | $240-$380 | Blower wheel material (aluminum vs. galvanized), bearing condition |
| Condenser coil cleaning (outdoor unit) | $180-$290 | Refrigerant line access, fin density, surrounding debris load |
| Full air handler cleaning (coil, blower, plenum) | $480-$680 | Plenum configuration, number of returns, presence of UV light interference |
| Heat exchanger inspection and cleaning | $220-$360 | Access panel configuration, rust scale severity, camera verification needed |
These are whole-system prices agreed in writing before work starts. We do not quote per-vent or per-register pricing. Factors that increase cost: units that have not been serviced since installation (common in 2015-2019 builds near West Cobb), systems with aftermarket modifications that complicate access, and jobs requiring weekend scheduling.

Why Marietta Homeowners Call CleanRun Duct Repair & Cleaning for Rotobrush Work
We’ve been serving Marietta since 2013, and the 52,000+ homes in our record include hundreds of Rotobrush systems - the Beast, the BrushBeast, the Predator, and the Lite models that contractors installed in the 2015-2020 new-construction boom around East Cobb and the Marietta Square. Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews, and they arrive identified by name with the equipment roster visible on the work order: Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, Guardsman.
We also service Lennox, Trane, and Carrier systems, which matters when a Marietta homeowner’s Rotobrush unit is integrated into a mixed-brand setup that the original installer left undocumented. The 365-Day Done Right Promise applies to every job, backed in writing. The Documented Photo Record is included on every visit, not offered as an upgrade. And if you have a written estimate from another company, we provide a Free Second Opinion at no cost - Haven Standard Clause 2.
FAQs
No - routine cleaning and maintenance by a qualified technician does not void the manufacturer’s warranty, provided no non-OEM parts are installed where the warranty explicitly requires them. We document every part used and its specification in the written job record, so the customer has evidence if a warranty claim arises. Call (470) 516-9337 if you need us to review your warranty terms before scheduling.
The clearest indicator is performance decline combined with unusual sound: a Beast series that once pulled 90 inches of water column and now pulls 60 likely has a brush motor or vacuum issue, not just dirty ducts. We scope the system first and show the customer the camera feed before recommending cleaning versus repair. The photo record makes the distinction visible.
Most parts are available direct from Rotobrush or through our distributor network, though some early Beast series components have been superseded by updated designs. When OEM is backordered, we use quality aftermarket parts from Nikro or Guardsman that match the original specification, and we note the substitution in writing with the customer’s approval. We do not install unbranded generic parts.
Repair makes sense when the unit is under ten years old, the failure is isolated to a single component, and the repair cost is under 40% of replacement. Replacement becomes the better recommendation when multiple systems have failed, the unit has been modified with non-standard parts, or the homeowner plans to sell within two years and needs documented reliability. We provide both numbers in writing and let the customer decide.
A single-system evaporator coil and blower cleaning takes 2.5 to 4 hours; a full air handler with condenser cleaning runs 4 to 6 hours. We schedule the full window and do not book overlapping appointments, so the technician stays until the work is complete and tested. Call (470) 516-9337 to schedule - estimates are free.
