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 makes solid equipment, but every duct system in Los Angeles eventually meets the same reality: earthquake movement, attic heat, and decades of air pushing through joints that were only ever taped. Here’s what we actually find when a Rotobrush system starts underperforming or making noise.
- Separated flex-duct connections on older Rotobrush installation runs. Many Los Angeles homes had Rotobrush flex duct or round rigid pipe installed during the 1990s and 2000s HVAC boom. The foil tape and plastic zip-ties used at connection points dry out, shrink, and separate. When that happens, you’re heating or cooling your attic or crawlspace instead of your living room. We re-secure the run with proper clamps and code-rated tape, not whatever was originally holding it.
- Bearing wear in Rotobrush brush-head motors. Rotobrush cleaning heads spin at high RPM, and after years of service in dusty, debris-heavy duct runs, the sealed bearings can wallow out or seize. If your Rotobrush head suddenly sounds like gravel in a blender and stops spinning under load, that’s bearings. We replace the bearing assembly and re-tension the brush head rather than selling you a whole new motor.
- Crushed or kinked aluminum riser tubes on Rotobrush system components. Rotobrush riser tubes take a beating, especially when homeowners store boxes next to them or kids inspect the garage. A kinked riser tube starves the blower for air, causing that hollow, wheezing sound. We straighten what’s salvageable and replace what isn’t, with tubes matched to your system’s diameter.
- Loose or sheared brush-head set screws on Rotobrush rotating assemblies. Vibration loosens the set screws that hold the rotating brush to the drive shaft. The brush then wobbles, scrapes the duct wall, and sounds like a dying appliance. We re-seat the assembly with thread-locking compound and check for shaft flat wear while we’re in there.
- OEM vs. aftermarket parts decisions on Rotobrush equipment. Here’s the honest version: Rotobrush OEM components cost more, often 40-60% more than quality aftermarket equivalents. For wear items like bristle rings, bearings, and set screw hubs, aftermarket parts from reputable suppliers perform identically. For drive motors and electronic controls, we recommend OEM. We’ll show you the cost difference and let you decide with full information, not pressure.
Our Rotobrush Air Duct Repair Process
When you call us for a Rotobrush repair in Los Angeles, here’s exactly what happens, in order.
- 1
We answer the phone. A live human picks up 24/7. You describe what’s going on, and we ask a few diagnostic questions. That conversation alone often narrows the problem down.
- 2
We quote the repair in writing. Based on what you tell us and our experience with Rotobrush equipment, we give you a written price range before we ever arrive. No surprise invoices at the end. That’s not how we work.
- 3
Your technician arrives, name and photo sent ahead. You’ll know exactly who’s coming to your door before they knock. They’ll show a photo ID badge and explain what they’re about to do. They wear a clean marked uniform and respect your home.
- 4
We diagnose and confirm the written price. The tech verifies the actual issue and locks the final price. If the fix costs less than quoted, you pay less. If it’s more involved, we talk it through with you before doing anything.
- 5
We repair, test, and document. The repair is completed, then tested under operating conditions. We check airflow, listen for noise, and verify the system pulls air correctly. You get before-and-after photos of the exact work done.
- 6
You receive the written 365-Day Done Right Promise. Every repair gets our guarantee in writing. If the covered repair fails within 365 days, we return and make it right at no charge. No fine print games.

Why Los Angeles Homeowners Call Linden Air Duct Cleaning for Rotobrush Work
We’ve been serving Los Angeles since 2004 as part of the Threshold Group family, and during that time we’ve repaired more Rotobrush equipment than we can count. What keeps people calling us back isn’t just that we know the equipment, though we do. It’s that we operate to the Threshold Standard on every single job: background-checked, identity-verified technicians, name and photo sent before arrival, photo ID shown at the door, and a written guarantee on every repair. Marcus Veale, who owns Linden Air Duct Cleaning, grew up in the Crenshaw district and trained through the HVAC program at Los Angeles Trade-Technical College. He’s been working on Los Angeles homes and apartment buildings for more than a decade, and he understands what this city’s heat, dust, and seismic activity do to ductwork. We also service equipment alongside Rotobrush from Lennox, Trane, and Carrier, so if your repair involves mixed components, we handle it in one visit. Clean ducts don’t fix everything, but dirty ones can quietly make a lot of things worse. And broken ones? They waste money every month they go unfixed.
FAQs
If your Rotobrush equipment is still under factory warranty, opening the motor housing or replacing sealed components yourself can void that coverage. Some Rotobrush warranties specifically exclude damage from unauthorized repair. We’re an independent Rotobrush service provider, not an authorized Rotobrush repair facility, so we’ll always tell you if your repair is warranty-sensitive before we proceed. When a repair might affect warranty status, we recommend contacting Rotobrush directly first. For systems out of warranty, which most Los Angeles units we see are, we repair without hesitation. Call (980) 447-2498 if you’re not sure where your system stands.
Most common Rotobrush components like bearings, set screw assemblies, and riser tubes are available within one to two business days from our local suppliers, and we keep the most frequent wear parts stocked on our trucks. Less common parts, like specific Rotobrush drive motors or control boards, typically arrive within three to five business days. We’ll tell you the parts timeline before we schedule any repair that requires ordering. Call (980) 447-2498 with your model number and we’ll check availability while you’re on the phone.
If your Rotobrush equipment is less than 15 years old and the issue is confined to a single component, repair is almost always the better financial call. We repair Rotobrush systems with failed bearings, separated connections, kinked riser tubes, and worn brush assemblies all the time, and those repairs extend equipment life substantially. Replacement becomes the better option when you’re dealing with multiple simultaneous failures, significant corrosion, or a drive motor that’s failed twice in three years. We’ll give you an honest recommendation based on what we find, even if that recommendation is to save your money. Call (980) 447-2498 for a straight answer.
Yes. Every Rotobrush repair we perform includes our 365-Day Done Right Promise in writing. If the covered repair fails within 365 days, we return and fix it at no charge. That’s a standing commitment on every job, not a promotional offer. You’ll receive the written guarantee with your invoice. Call (980) 447-2498 if you have questions about what a specific repair covers.
Most homeowners insurance policies don’t cover mechanical wear and tear on duct systems, including Rotobrush components. Coverage is typically reserved for sudden events like fire, water damage from a covered peril, or earthquake damage if you carry a separate earthquake policy. If your Rotobrush repair is connected to a covered event, we can provide documentation and photos for your insurance claim. For general repair work, we keep our pricing straightforward and give you the written number before we start. Call (980) 447-2498 for a free estimate.
If you have a Rotobrush system that’s acting up in Los Angeles, call (980) 447-2498. We’ll give you an honest read on what’s wrong and what it will cost to make it right, before you spend a dollar.
