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.

AfterRotobrush HVAC Cleaning in Rockville: What to Know First
CleanRun Duct Repair & Cleaning provides independent Rotobrush service in Rockville, with most HVAC cleaning jobs completed in a single scheduled visit. We quote a written, flat price before any work begins, and every duct run is photographed before and after so you can see what was actually done. Call (240) 255-4519 for a free estimate.
This page is for Rockville homeowners who own Rotobrush equipment and need evaporator coil cleaning, blower cleaning, condenser cleaning, air handler cleaning, heat exchanger cleaning, or coil treatment. We are not affiliated with or authorized by Rotobrush. We are an independent Rotobrush service provider that services the equipment based on field experience, manufacturer documentation, and trade-standard practices.
How Rotobrush Products Fail - and How We Fix Them
- Rotobrush BrushBeast series: motor housing seal degradation in humid seasons. The BrushBeast’s vacuum motor housing uses a felt-and-rubber seal arrangement that softens during Rockville’s July-August humidity spikes. We see this most in homes near Rock Creek, where basement humidity stays elevated. The seal compression drops, fine debris bypasses the filter, and the blower wheel loads up with particulate. We replace with OEM-spec silicone seals and verify static pressure recovery before we leave.
- Rotobrush aiR+ XP: flex-duct adapter fatigue at the plenum connection. The aiR+ XP’s proprietary flex-duct adapter, PN 8500-A, develops stress cracks where it meets the sheet-metal plenum, especially in older Rockville split-levels with original 1980s ductwork near Congressional Plaza. The crack pulls conditioned air into the attic or crawl space. We source the adapter from Rotobrush or match it with a Guardsman-certified equivalent, then seal with mastic, not tape.
- Rotobrush Beast series: HEPA filter collapse under heavy debris load. The Beast’s HEPA cartridge is rated for residential dust loading, but Rockville’s pollen density, oak and maple in particular, can saturate it in a single heavy season. Collapsed filters dump debris back into the air handler. We inspect filter integrity with a borescope before quoting, stock the correct 24x24x6 OEM cartridge, and document the pre-collapse condition in your photo record.
- Rotobrush aiR+ series: condensate pan overflow due to drain line biofilm. The aiR+ line’s shallow condensate pan, designed for compact installation, doesn’t tolerate partial clogs. Rockville’s municipal water chemistry leaves a calcium-rich biofilm that narrows the 3/4-inch PVC drain. We clear with controlled nitrogen pressure, treat the pan with a non-corrosive antimicrobial, and verify flow rate at the exterior termination.
- Rotobrush hybrid systems: cross-contamination between supply and return during coil cleaning. Some Rockville homeowners pair Rotobrush duct cleaning with a separate HVAC service, leaving the coil wet and the return side open. We isolate the plenum with temporary block-off plates, clean the evaporator coil with a foaming agent matched to the fin material, and run a negative-pressure extraction before restoring airflow. No wet coil goes back online without a dry-bulb verification.
Our Rotobrush HVAC Cleaning Process
- 1
Call and scheduling. A live person answers. We ask for your Rotobrush model number, age, and the symptom you’re seeing. We schedule a two-hour arrival window.
- 2
On-site inspection with borescope and photo documentation. Tomas Reyes or a Haven Standard Clause 3: Verified Crew technician inspects every duct run, the coil, the blower assembly, and the condensate path. The photo comes first. The price comes after.
- 3
Written price delivered before work starts. Haven Standard Clause 1: no exceptions. The scope lists every component, the flat price per system, and the 365-Day Done Right Promise.
- 4
Service execution with OEM or quality aftermarket parts. We use Rotobrush-specified components where available, or cross-reference to Nikro, Abatement Technologies, or Guardsman equivalents that meet or exceed OEM pressure and temperature ratings. We do not substitute unlisted generics.
- 5
Post-service testing and photo record delivery. We verify static pressure, temperature split, and condensate flow. Your documented photo record, including before-and-after images of every duct run and component cleaned, is delivered before the crew leaves.
- 6
Written guarantee activation. The 365-Day Done Right Promise is dated and signed. If the work is not right, we make it right.

Why Rockville Homeowners Call CleanRun Duct Repair & Cleaning for Rotobrush Work
We’ve been running jobs across Rockville since 2013, including plenty of work in the older split-levels near Congressional Plaza where the original flex duct tends to show its age in ways that aren’t obvious until you pull the register cover. Our crew includes technicians trained on Rotobrush, Lennox, Trane, and Carrier systems, so we’re not guessing when your equipment needs something outside the standard protocol.
Every job carries the 365-Day Done Right Promise in writing, not as a verbal assurance. Every visit produces a Documented Photo Record of every duct run, before and after, delivered to you as a standard deliverable. Our equipment roster, Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, and Guardsman, is published here so you can verify what we use before agreeing to a price.
We also provide Free Second Opinion on any written estimate. Bring a competitor’s quote; we put our number next to it in writing.
FAQs
No. As an independent Rotobrush service provider, our work does not extend or activate any manufacturer warranty. We service the equipment based on field experience and trade-standard practices. If your Rotobrush system is under factory warranty, contact Rotobrush directly for authorized service. We document our work so you have a record of what was done and when.
We source OEM Rotobrush parts when available and when lead times are reasonable. For common wear items like the aiR+ XP flex-duct adapter or Beast HEPA cartridges, we also stock Guardsman-certified and Nikro-cross-referenced equivalents that meet or exceed OEM pressure and temperature specifications. We tell you which we’re using before we start, and we don’t substitute unlisted generics.
We inspect with a borescope and measure static pressure before quoting either. If the blower motor draws within 10% of nameplate amperage, the housing is structurally sound, and the coil fins are more than 70% intact, cleaning is usually the right call. If the heat exchanger shows cracks, the cabinet is rusted through at the plenum, or repair parts are obsolete, we’ll show you the photo and recommend replacement. Call (240) 255-4519 and we’ll put an exact number on both options in writing.
A single-component cleaning, coil or blower, typically takes two to three hours on site. A full system cleaning runs four to six hours. We schedule by the job, not by the hour, so we’re not rushing to hit a dispatch window. The crew arrives in a CleanRun uniform, identified by name before arrival under Haven Standard Clause 3: Verified Crews.
A blower wheel loaded with debris or a coil choked with buildup can raise static pressure and reduce airflow, which makes the system run longer to hit thermostat setpoint. Cleaning restores design airflow. We measure and photograph the before-and-after static pressure so you can see the change, not just take our word for it. Call (240) 255-4519 for an estimate.
