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 BrushBeast and BrushBeast II - wet debris corrosion in the blower housing. These units pull high airflow through flexible ducting, and in Northbrook’s humid July-August stretches, condensation builds in the lower housing where the brush motor sits. We’ve opened BrushBeast housings in Northbrook homes near Techny Basin to find green corrosion on the motor terminals that the owner never smelled or heard. We disassemble the housing, treat the corroded contacts, and apply a moisture barrier seal to prevent recurrence.
- Rotobrush aiR+ XP and aiR+ XP Plus - UV lamp socket degradation from voltage fluctuation. Northbrook’s older grid infrastructure, particularly in neighborhoods west of Waukegan Road built in the 1960s and 70s, delivers inconsistent voltage that fries the ceramic UV sockets after 18-24 months. The lamp still glows, but output drops below effective sanitizing levels. We meter the socket under load, replace with ceramic-rated aftermarket sockets where OEM backorder stretches past two weeks, and document the before/after UV intensity with a radiometer reading in your job record.
- Rotobrush DuctMaster and DuctMaster Pro - HEPA media collapse from high-static pressure. These portable units get wheeled into tight Northbrook basements with low ceiling heights, and owners often forget to check the pre-filter. When the HEPA loads up, the backward pressure cracks the pleat separators. We replace with Abatement Technologies HEPA media rated for the same airflow, photograph the cracked original, and log the static pressure reading so you know when the next change is due.
- Rotobrush air handler mount units - drain pan biofilm that defeats sanitizing treatment. The shallow drain pan under Rotobrush’s AH-series mounts sits above the evaporator coil, and in Northbrook’s spring when the condensate line backs up with cottonwood seed, the pan grows a pink bacterial film. Spraying the ducts without addressing the pan is vacuum noise - the biofilm re-seeds within weeks. We pull the pan, mechanically clean it, treat with a non-residual sanitizer, and only then proceed to the duct run treatment.
- Rotobrush portable and truck-mount vacuum motors - seal failure from fine particulate bypass. The motor shaft seal on older Rotobrush vacuums, especially units run without the secondary filter sock, ingests fine mold spore particulate that scores the seal face. You hear it first as a whine that climbs pitch under load. We replace the seal with a fluorocarbon-rated aftermarket equivalent, check shaft runout with a dial indicator, and bench-test the motor before it goes back in your equipment - not just “seems fine.”
Our Rotobrush Air Quality & Sanitizing Process

- 1
System survey and photo documentation. We photograph every accessible duct run, the plenum (the main distribution box connected to your air handler), and the Rotobrush unit itself before touching anything. The camera doesn’t negotiate - it just shows you what’s there.
- 2
Written scope and price, Haven Standard Clause 1. Tomas Reyes or a senior tech reviews the photos with you on-site, identifies contamination type and extent, and delivers a written price for the full scope before any panel comes off.
- 3
Mechanical agitation and negative-pressure extraction. We use Rotobrush, Nikro, or Abatement Technologies equipment as appropriate for your duct material - flex duct gets softer brush contact, metal duct gets more aggressive agitation - with concurrent negative-pressure extraction so dislodged debris leaves the system, not your living room.
- 4
Sanitizing treatment matched to the finding. Mold, bacteria, or odor each gets a different treatment protocol. We apply EPA-registered sanitizer through a fogging nozzle at the plenum, with dwell time documented, and run the Rotobrush unit on recirculate to distribute through all branches.
- 5
UV or air purifier installation if specified. For Rotobrush aiR+ XP units needing lamp replacement, or new Honeywell or Aprilaire whole-house purifier installs, we complete electrical connections, test voltage at the socket under load, and photograph the installed unit.
- 6
Post-treatment photo record and 365-Day Done Right Promise documentation. Every duct run is photographed after treatment. You receive the full photo record, the written scope, and the written guarantee before we leave.

AfterWhat Rotobrush Air Quality & Sanitizing Costs in Northbrook
| Service | Typical Range | What Moves the Price |
|---|---|---|
| Whole-system duct sanitizing (mold or bacteria) | $380 - $580 | Number of duct runs, severity of contamination, accessibility of plenum |
| Odor removal treatment (smoke, pet, musty) | $320 - $520 | Source location, whether thermal fogging is needed, number of returns affected |
| UV light replacement (Rotobrush aiR+ XP series) | $180 - $340 | Socket condition, lamp wattage, whether voltage conditioning is recommended |
| Whole-house air purifier install (Honeywell, Aprilaire, Guardsman) | $580 - $920 | Unit capacity, electrical run length, integration with existing Rotobrush or HVAC controls |
| Allergen reduction package (sanitizing + HEPA upgrade) | $480 - $720 | Filter housing modifications needed, number of returns, pre-existing duct leakage |
These are whole-system prices, not per-vent teasers. We do not quote $79 coupons that balloon on arrival - Haven Standard Clause 1 means the written price is the price. Northbrook’s older homes, particularly the split-levels and ranches near Northbrook Court built 1965-1985, often need more time due to original flex duct that has settled and compressed. We price for the actual work, then do it. Call (224) 351-9772 for a free estimate - we’ll put our number next to any competitor’s written quote, no cost.
Why Northbrook Homeowners Call CleanRun Duct Repair & Cleaning for Rotobrush Work

We’ve worked Northbrook long enough to know which houses have the original Rotobrush installs from the 2008-2012 retrofit wave, and which have newer aiR+ XP units that need different handling. Our crew is background-checked and uniformed under Haven Standard Clause 3: Verified Crews, and we identify the technician by name before arrival.
The 365-Day Done Right Promise is not a policy subject to manager approval - it’s a written guarantee on every job. If the mold smell returns, if the UV lamp fails early, if the odor treatment didn’t hold, we make it right. No charge for the callback, no argument about whose fault it was.
We also service Lennox, Trane, and Carrier air quality systems, so if your Rotobrush unit is integrated with a mixed-brand HVAC setup, we’re not guessing at the control wiring. Since 2013, we’ve served 52,000+ homes with a written price before work started and a Documented Photo Record when we left. Northbrook homeowners who bought between 2015 and 2025 at high price points tend to ask hard questions about what they’re paying for - we built this company to have answers in writing.
FAQs
No, professional sanitizing does not void your Rotobrush warranty, provided the work is done without disassembling sealed electrical components. As an independent Rotobrush service provider, we document every step and use manufacturer-specified or equivalent parts so warranty coverage remains intact. If your unit is still under original warranty, we’ll note the serial number and service date in your job record for your files. Call (224) 351-9772 if you need help locating your warranty paperwork.
You receive a Documented Photo Record of every duct run before and after treatment, plus a written scope stating what was applied, at what concentration, and for what dwell time. For UV installations, we include a radiometer reading showing output in microwatts per square centimeter. We do not ask you to trust a smell or a feeling - the photo and the meter reading are in your job record. If results don’t match what was documented, the 365-Day Done Right Promise applies.
Repair makes sense when the core blower or vacuum motor is sound and the issue is localized - a failed UV socket, a cracked HEPA housing, a contaminated drain pan. Replacement is the better value when the unit has multiple failure points, parts are on indefinite backorder, or the original design no longer meets your home’s air quality needs. We give you both numbers in writing and let you decide, no pressure. Bring us a competitor’s replacement quote and we’ll put our repair estimate next to it under our Free Second Opinion.
Most residential sanitizing and UV replacement jobs in Northbrook finish in 2.5 to 4 hours. Whole-house air purifier installs run 4 to 6 hours depending on electrical routing. We do not quote same-day dispatch - duct work is scheduled, not emergency response - and we confirm your appointment window by text the evening before. Call (224) 351-9772 to check next available dates.
OEM parts match the original specification exactly, which matters for warranty coverage and exact fit. Quality aftermarket parts from Abatement Technologies, Honeywell, or Guardsman often perform equivalently at lower cost, and we stock both. When OEM backorder stretches past two weeks - common for Rotobrush UV sockets in peak season - we offer the aftermarket equivalent with the same electrical rating, document the substitution in your job record, and warranty our installation under the 365-Day Done Right Promise either way.
