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 Dryer Vent Cleaning in Los Angeles: What to Know First
Rotobrush dryer vent cleaning in Los Angeles typically runs $160 – $280 for a standard single-family home, and we complete most jobs in 60 – 90 minutes. We’re an independent Rotobrush service provider – not affiliated with or authorized by the manufacturer – and we clean, inspect, and repair the full range of Rotobrush-recommended dryer vent systems using the same professional-grade rotary brush technology the brand is known for. If your Rotobrush system hasn’t been touched in two years or more, you’re likely overdue.
This page is for Los Angeles homeowners who want a straight answer on what Rotobrush dryer vent cleaning costs, what actually gets done, and why it matters in this climate. Call (737) 727-2314 for a free estimate – a live person answers, and you’ll get a written price before any work starts.
How Rotobrush Products Fail – and How We Fix Them
Rotobrush equipment is solid, but the vent systems it maintains have real failure patterns in Los Angeles. Here’s what we see most often, and what we do about it:
- Lint accumulation at the transition elbow. The 90-degree bend right behind the dryer is the single most common clog point on systems serviced by Rotobrush machines. Lint slows through that bend, stacks up, and eventually chokes airflow. We clear it with a Rotobrush BR-1000 rotary brush configured with a reverse-sweep head, then vacuum the loosened debris with a Nikro HEPA unit so it never re-enters your laundry room air.
- Bird and rodent nesting in flapper-style caps. Los Angeles’s warm, dry climate makes exterior vent caps prime real estate for birds building nests. A plugged cap means hot, moist air has nowhere to go, so it backs up into the dryer and trips the overheat sensor. We replace flapper caps with louvered bird-guard models – aftermarket caps from Guardsman are our go-to – and provide before-and-after photos so you see the obstruction for yourself.
- Crushed or kinked foil transition hose. If your dryer was installed by a big-box delivery crew, chances are the foil transition hose is crimped behind the unit. We see this on roughly one in four first-time Rotobrush service calls in neighborhoods like Sherman Oaks and North Hollywood. A 4-inch rigid metal duct replaces the foil section, and lint stops collecting at the pinch point. Rotobrush’s own manuals recommend rigid ducting precisely for this reason.
- Dryer overheating from a clogged internal blower wheel. This is the one most homeowners miss. The vent itself looks clear because a Rotobrush machine pulled the visible lint, but lint inched past the filter and wrapped around the blower wheel inside the dryer cabinet. It’s a fire hazard and it shortens dryer life. We pull the front panel, clean the blower wheel, and test the high-limit thermostat – all included in our deep-clean service.
- Vent runs exceeding safe length. In Los Angeles, especially in older mid-century homes that run vents through the roof rather than a side wall, the vent run is often longer than the 25-foot maximum recommended by Rotobrush and most dryer manufacturers. Every foot over that limit adds resistance, and every bend subtracts 5 feet of effective run. We measure the actual run during our inspection – this is information you won’t find on Rotobrush’s website – and if it’s over spec, we’ll recommend a booster fan or a rerouting option that brings the system back to safe operating range. If it’s under 25 feet but clogging repeatedly, the issue is usually the transition hose or cap, not the main run.
Our Rotobrush Dryer Vent Cleaning Process
Here’s exactly what happens from the moment you call:
- 1
Phone consultation. A live person answers at (737) 727-2314. You tell us about your dryer, the age of the home, and any symptoms – longer drying times, a hot dryer, a burning smell. We’re listening for the right clues before we ever knock on your door.
- 2
On-site inspection. Our background-checked technician arrives in uniform, introduces themselves by name, and walks the vent path with you. We check the transition hose, the exterior cap, the visible ducting in the garage or crawlspace, and measure the total run length. Omar Haddad, our Owner and Lead Technician, has been pulling apart L.A. laundry rooms for over a decade, and if there’s an issue upstream of the vent, he’ll spot it.
- 3
Written price, before any work. You get a quote on the spot. No “we’ll see what we find” games. The number on the sheet is the number you pay, full stop.
- 4
Rotobrush rotary brush cleaning. We run a Rotobrush brush system through the full vent run, breaking up compacted lint and debris. Simultaneously, a Nikro HEPA-rated vacuum creates negative-pressure extraction – that means the loosened debris goes straight into the vacuum, not back into your living room. For longer runs in larger Los Angeles homes, we stage Abatement Technologies containment units to keep the work area clean.
- 5
Parts replacement and reassembly. If the cap, transition hose, or any connector needs replacement, we use OEM Rotobrush-compatible parts or quality aftermarket components from Guardsman. We’ll explain what we’re installing and why, with the price already covered in your written quote.
- 6
Post-clean airflow test. We run the dryer through a cycle and verify airflow at the exterior cap using an anemometer. You see the before-and-after photos, we verbally walk you through what changed, and the 365-Day Done Right Promise applies from that moment forward.
What Rotobrush Dryer Vent Cleaning Costs in Los Angeles
Honest numbers, because nobody should book a service blind:
| Service | Typical Los Angeles Price Range |
|---|---|
| Standard single-family Rotobrush dryer vent cleaning (vent run under 25 ft, one story) | $160 – $220 |
| Deep clean including blower wheel service and lint trap housing | $220 – $280 |
| Roof-vent systems, two-story homes, or runs over 25 ft | $280 – $350 |
| Vent cap replacement (bird guard, louvered) | $45 – $90, parts and labor included |
| Transition hose replacement (rigid metal) | $40 – $70, parts and labor included |
What moves the price: roof access, abnormal vent run length, multiple dryers, or a blower wheel that’s never been serviced. What doesn’t move the price: the sales pitch. Your quote is written before work starts, and it doesn’t change at the door. Call (737) 727-2314 for your exact number – estimates are free.

Our techs work on Rotobrush-recommended vent systems daily, and we maintain the supporting ecosystem too: Lennox, Trane, and Carrier units show up regularly in Los Angeles laundry rooms, and we know how their airflow characteristics interact with vent conditions.

FAQs
No, professional vent cleaning does not void a Rotobrush or dryer manufacturer warranty – in fact, neglect can. Most dryer warranties require proof of regular maintenance if a claim involves overheating or airflow failure. We document every job with before-and-after photos, and if a warranty claim needs supporting evidence, you’ll have it. We’re an independent Rotobrush service provider, not a manufacturer-authorized agent, so we’ll never claim to represent Rotobrush directly – but our work meets and exceeds the maintenance standards their documentation calls for. Call (737) 727-2314 to schedule an inspection before your warranty cycle gets complicated.
Every 12 to 18 months for a single-family home, and every 6 to 12 months if you run laundry more than five loads a week, have pets, or your vent exits through the roof. Los Angeles’s warm, dry climate accelerates lint compaction – it bakes onto duct walls rather than staying loose. If your dryer takes more than one cycle to fully dry a load, you’re already past due. Call (737) 727-2314 and we’ll tell you honestly whether you need service now or can wait.
Because they’re not doing the same job. A truck-mounted shop vacuum with a short hose reaches maybe 8 to 10 feet into the vent. A proper Rotobrush rotary brush system with a Nikro HEPA vacuum reaches the full 25-foot run, including the transition elbow behind the dryer and the exterior cap. The cheap quote is usually a teaser to get a technician in the door, and the price climbs once they’re standing in your laundry room. Our quote comes in writing before any work starts – and that number is the number you pay. Call (737) 727-2314 for a real, complete price.
You’ll see proof. Before-and-after photo documentation is standard on every job – we photograph the interior vent, the exterior cap, and any parts we replace. Our techs walk you through what was removed and why the system is now clear, and we test airflow at the cap before we leave. That’s The Relay Standard: no “trust me, it’s done.” You see it. Call (737) 727-2314 for a job you can verify with your own eyes.
Yes, and most repairs are cheaper than replacement. We replace crushed transition hoses, missing or damaged vent caps, and reroute vent runs that exceed safe length. If a repair is made, you get a written guarantee on that repair, plus a free second visit if it fails – that’s part of the 365-Day Done Right Promise. Call (737) 727-2314 for an inspection, and we’ll tell you what’s repairable before we quote anything.
