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 Aurora: What to Know First
We provide independent Rotobrush air quality and sanitizing service in Aurora, typically completing mold treatment, bacteria sanitizing, and UV light installations within one scheduled day. Every job starts with a written flat price before any work begins, and every duct run is photographed before and after as part of our standard documented photo record. If you own a Rotobrush air scrubber, duct cleaning system, or portable HEPA unit and need sanitizing, odor removal, or allergen reduction in Aurora, we quote real numbers you can hold in your hand. Call (720) 513-5159 for a free estimate.
How Rotobrush Products Fail - and How We Fix Them
- Beast Series brush motor housing seal degradation. The Beast’s high-torque motor generates enough heat to harden the lower housing gasket over two to three Aurora heating seasons. Once the seal cracks, dust bypasses the HEPA stage and recirculates through the plenum - the main air distribution box connected to your furnace. We replace the gasket with an OEM-spec silicone seal and verify negative-pressure integrity with a smoke pencil before the unit goes back into service.
- BrushBeast Plus UV-C lamp socket corrosion. The 24-volt lamp socket in the Plus series sits in the airstream path where condensation collects during Aurora’s spring humidity swings. Corroded contacts either flicker or fail to energize the germicidal lamp entirely, leaving the unit as a passive filter. We clean the socket with contact-specific solvent, install a moisture-resistant ceramic replacement when available, and test UV output with a radiometer - not just a visual check.
- Rotobrush aiR+ XP motor bearing wear from fine particulate. The XP’s sealed bearings aren’t fully sealed against drywall dust and pet dander, both common in Aurora’s newer E-470 corridor builds with active construction nearby. Grit intrusion causes harmonic vibration that transfers into the duct run walls. We disassemble the brush head, clean and repack bearings where possible, or source quality aftermarket replacements that match OEM torque specs without the dealer markup.
- Portable HEPA unit carbon pre-filter saturation. Rotobrush’s standalone air purifiers use a bonded carbon layer that saturates faster in Aurora homes with finished basements - the clay-heavy soil off-gasses radon progeny and moisture that load the carbon prematurely. Owners smell a sour, metallic odor and assume the HEPA is failing. We test airflow and pressure drop across the filter bank, replace only the saturated stage, and show you the used filter under a work light before discussing replacement intervals.
- BrushBeast contactor pitting from frequent cycling. In Aurora’s shoulder seasons, systems short-cycle as temperatures swing thirty degrees in a day. The BrushBeast’s contactor points arc and pit, causing intermittent power to the sanitizing stage. We mic the contact surfaces, replace the contactor with a heavy-duty aftermarket unit rated for more cycles, and recommend a delay timer to reduce wear going forward.
Our Rotobrush Air Quality & Sanitizing Process

- 1
Call and scope. You describe the Rotobrush model, symptoms, and what you’ve noticed. We schedule a visit and note any warranty considerations - we are an independent Rotobrush service provider, not authorized by the manufacturer, so we flag what work preserves remaining coverage and what voids it.
- 2
On-site diagnostic with photo documentation. We open the plenum and first duct run, insert a borescope, and photograph what we find. In Aurora’s older ranch homes near the Aurora Hills Golf Course, we regularly see three-inch debris build-up at the first elbow where the brush head loses contact pressure.
- 3
Written price before work starts. Haven Standard Clause 1: we deliver a flat price per system, agreed in writing, before any panel comes off. No per-vent pricing, no add-ons after the truck is in your driveway.
- 4
Repair or sanitizing with OEM or quality aftermarket parts. We source Rotobrush-compatible components and name the manufacturer on your invoice - Guardsman antimicrobial treatments, Honeywell UV lamps where cross-compatible, Nikro HEPA media when OEM is backordered.
- 5
Test and verify. We run the unit through a full cycle, measure airflow at the register (the visible vent cover in each room), and capture after photos of every duct run accessed.
- 6
Deliver the documented photo record and written guarantee. Your job file includes before-and-after images, the scope of work, parts used, and the 365-Day Done Right Promise - if it’s not right, we make it right, backed in writing.

| UV-C light installation (new mount, ballast, lamp) | $520-$780 | Plenum access; 120V vs. 24V wiring run |
These are whole-system prices, not per-vent come-ons. The final number depends on what the camera shows and what your Rotobrush model requires. We put it in writing before starting. Call (720) 513-5159 for an exact quote - estimates are free.
Why Aurora Homeowners Call CleanRun Air Duct Cleaning Aurora for Rotobrush Work

We’ve been running Rotobrush jobs in Aurora since 2013, from the older ranches with galvanized ductwork near Havana Street to the tight, flex-duct new builds along the E-470 corridor. Tomas Reyes, our owner and lead technician, keeps detailed before-and-after photos for every one of them - his habit from years of explaining HVAC service across the metro area. We also service Lennox, Trane, and Carrier air quality systems, so when a Rotobrush unit sits upstream of a Carrier Infinity air purifier, we understand how the two interact. Haven Standard Clause 3: Verified Crews means our technicians are background-checked, uniformed, and identified by name before arrival. The 365-Day Done Right Promise applies to every job, and our license number is published here, not buried in a footer.
FAQs
It depends on remaining coverage and the work performed. As an independent Rotobrush service provider, we assess your warranty status before starting and flag which repairs preserve coverage and which don’t - then you decide. We document this conversation in writing as part of your job record. Call (720) 513-5159 to schedule.
We show you the photo first, then we talk about what comes next. Your documented photo record includes borescope images of the duct run interior before and after treatment, plus airflow measurements at the register. For UV installations, we test lamp output with a radiometer and record the reading on your invoice. If results don’t match what we documented, the 365-Day Done Right Promise applies.
Repair makes sense when the brush motor and housing are sound and the failure is isolated to the sanitizing stage, UV socket, or filter bank - typically under $600 in our Aurora pricing. Replacement becomes the better value when multiple stages fail simultaneously or when the unit is past seven years and parts availability tightens. We quote both paths in writing when asked. Call (720) 513-5159 for a free second opinion on any written estimate.
Most residential jobs run three to five hours from arrival to final test, depending on duct run count and whether we need to access the plenum through a custom cut. We schedule a specific arrival window, not an all-day wait. You’ll receive the documented photo record and written scope before we leave.
We carry common Rotobrush service components - brush heads, seals, UV lamps, contactors - on our Aurora trucks. For specialized aiR+ XP bearings or discontinued Beast series housings, we source quality aftermarket equivalents with matched specifications rather than waiting on factory backorders. We tell you during the estimate call if your model requires a parts order.
Ready for a written price on your Rotobrush air quality or sanitizing job in Aurora? Call (720) 513-5159. A live person answers, 24/7.
