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 Littleton: What to Know First
We provide independent Rotobrush air quality and sanitizing in Littleton, with most jobs scheduled within a week and completed in a single visit. Every job starts with a written price before any work begins - no per-vent add-ons, no surprises - and ends with a documented photo record of every duct run we touch. If you own a Rotobrush system and need mold treatment, bacteria sanitizing, odor removal, UV light installation, or allergen reduction, we’ll inspect first, quote in writing, and show you what the camera found before we start. Call (720) 315-7291 for a free estimate.
How Rotobrush Products Fail - and How We Fix Them
- Rotobrush aiR+ XP and aiR+ XP Gold units with degraded brush contact seals. The flexible shaft housing on these series develops micro-gaps where the brush head meets the shaft collar, allowing debris to bypass the extraction point and recirculate into the plenum - the main distribution box that feeds air to every room. We replace the seal with OEM-spec fluorocarbon rings or, when supply is thin, matched aftermarket equivalents rated to the same temperature and particulate load. The camera doesn’t negotiate - it just shows what’s there.
- Rotobrush Beast series with clogged negative-pressure ports. The Beast’s higher CFM design pulls heavier debris loads, but the side extraction ports on units running in Littleton’s older Columbine Knolls homes often cake with drywall dust from original construction that was never fully cleared. We disassemble the port housing, mechanically clear the blockage, and verify flow rate with a digital manometer - a pressure gauge that reads suction in inches of water column - before the unit goes back into service.
- Rotobrush aiR+ Classic with cracked flex-duct adapter collars. The injection-molded collar on early aiR+ Classic units becomes brittle after repeated thermal cycling in Colorado’s dry climate, particularly in south-facing utility rooms where attic heat spikes the ambient temperature. We machine-fit replacement collars from Abatement Technologies’ universal adapter line, which uses a glass-filled nylon rated for wider temperature swings than the original ABS.
- Rotobrush BrushBeast with premature HEPA filter loading. The BrushBeast’s larger motor moves more air, but owners in Littleton’s newer Ken Caryl Valley builds often find the HEPA cartridge loading in half the rated interval - a symptom of fine silica dust from nearby construction that slips past standard pre-filtration. We source Guardsman MERV-16 pre-filters with deeper pleat spacing, which extends HEPA life and reduces the long-term parts cost without voiding the motor warranty.
- Rotobrush aiR+ XP with failed UV-C lamp ballasts. The integrated UV-C module on aiR+ XP sanitizing configurations uses a magnetic ballast that fails open-circuit after roughly 8,000 hours - shorter in homes with voltage fluctuation common in Littleton’s older grid sections near Bowles Avenue. We test lamp output with a UV-C radiometer, replace the ballast with an electronic rapid-start unit from Honeywell’s commercial line, and verify 253.7 nm wavelength output before we leave.
Our Rotobrush Air Quality & Sanitizing Process

- 1
Inspection and documentation. We feed a borescope camera - a flexible fiber-optic probe - into the first duct run to record debris load, microbial staining, and flex duct integrity before we quote anything.
- 2
Written price delivery. Haven Standard Clause 1: the price is printed, itemized, and signed before any panel comes off. No verbal estimates, no “we’ll see once we’re in there.”
- 3
Parts verification. For Rotobrush units, we verify whether OEM parts are available from current distributor stock or whether a quality aftermarket equivalent meets the same specification - we document which we used and why in your job record.
- 4
Service execution with photo record. Every duct run is photographed before and after treatment or repair. For sanitizing jobs, we note product concentration, dwell time, and ventilation protocol per manufacturer label.
- 5
System test and sign-off. We run the unit through a full cycle, measure static pressure at the plenum, and deliver your photo record and written warranty before we pack tools.
- 6
365-Day Done Right Promise activation. The written guarantee goes into effect the moment we leave - if the work is not right, we make it right, no manager approval required.

Why Littleton Homeowners Call CleanRun Air Duct Cleaning Littleton for Rotobrush Work

We’ve been cleaning and repairing ductwork in Littleton since 2013, including plenty of jobs in Columbine Knolls where the homes are older and the duct liners tell a longer story than the listing price suggests. Tomas Reyes and our crew know Rotobrush equipment from hands-on service, not from a distributor brochure - we also work on Lennox, Trane, and Carrier systems, which means we understand how your Rotobrush unit interacts with the rest of your HVAC stack rather than treating it as an isolated component. Every technician is background-checked and uniformed under Haven Standard Clause 3: Verified Crews, identified by name before arrival. The 365-Day Done Right Promise is backed in writing on every job, and your photo record is delivered as a standard deliverable, not an upsell.
FAQs
No. As an independent Rotobrush service provider, we use parts and practices that meet or exceed OEM specifications, and we document everything we do in your job record. Manufacturer warranty coverage for defects in materials or workmanship remains intact; our 365-Day Done Right Promise covers our labor and parts selection separately. If you have a specific warranty concern, bring your paperwork and we’ll review it before we start - call (720) 315-7291.
We recommend replacement when the repair cost exceeds 60% of a comparable new unit’s installed price, or when the unit has repeated failures of the same component within two years. For most aiR+ XP and Beast series units under eight years old, repair is the better value. We make this recommendation in writing, with the math shown, before you decide - call (720) 315-7291 for an inspection.
OEM parts are available for current-production aiR+ XP, Beast, and BrushBeast lines with typical distributor lead times of 3-5 business days. For discontinued aiR+ Classic components and certain UV-C modules, we source quality aftermarket from Guardsman, Abatement Technologies, and Honeywell - brands you can verify independently. We document which we used and why in your written job record.
In Littleton’s climate - dry winters, moderate summers, and periodic wildfire smoke intrusion - we see meaningful microbial load accumulation every 3-5 years in homes with standard filtration, and every 5-7 years in homes with upgraded MERV-13 or better filters. Homes with finished basements or evaporative cooling tend toward the shorter interval. We verify actual need with camera inspection rather than selling on a calendar - call (720) 315-7291 to schedule.
You receive three items: a written scope of work with the final price, a photo record showing the interior of every duct run before and after service, and the 365-Day Done Right Promise in writing. These are standard deliverables on every job, not optional add-ons.
Ready to see what your ducts actually look like? Call (720) 315-7291 for a free estimate. We’ll inspect first, quote in writing, and show you the camera footage before any work begins - Haven Standard Clause 1, every time.
