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 Duct Cleaning in Los Angeles: What to Know First
Rotobrush air duct cleaning in Los Angeles typically costs $450-$850 for a full residential system, depending on the number of vents and the level of buildup we find inside. We’re an independent Rotobrush service provider, not affiliated with the manufacturer, and we clean systems using Rotobrush equipment along with Nikro and other professional-grade tools. Most Los Angeles homes take about 3-5 hours from setup to final walkthrough.
If you own a home with Rotobrush-cleaned ducts and you’re wondering whether it’s time again, or you’ve noticed dust settling faster than it used to, this page is for you. We’ll walk through what we actually find inside Rotobrush-cleaned systems in Los Angeles neighborhoods, what it costs, and how the process works from the first call to the photo of the clean-up before we leave. Call (323) 918-4345 if you’d rather just talk it through with a live person.
How Rotobrush Products Fail - and How We Fix Them
Rotobrush systems are solid workhorses, but like any tool used in hundreds of Los Angeles homes, they develop habits. Here’s what we see on the duct side, not just the machine side:
- Rotobrush aiR+ and RotoStorm units leave a distinctive spiral pattern in flex duct interiors. The rotating brush head travels in a helix, and in older Los Angeles homes with original flex duct from the 70s and 80s, that spiral creates ridges where fine dust accumulates faster than it would on smooth metal. We slow the feed rate on flex runs and make a second pass when we see that pattern, because one pass often isn’t enough.
- The Rotobrush brush head can’t fully reach the last few inches of a capped supply run. This is true of every rotating brush system, but with Rotobrush’s fixed-length shaft sections, the issue shows up in Los Angeles tract homes where supply runs dead-end close to exterior walls. We carry angled whip attachments and manual tools to finish what the rotary head starts.
- Return ducts in Los Angeles homes with pets can compact pet hair into the first elbow. Rotobrush’s vacuum is strong, but dander and hair in a hot attic can bake onto metal surfaces between cleanings. We use a pre-agitation step with our Nikro air tools before the Rotobrush head goes in on return runs where we spot this during the camera inspection.
- Rotobrush vacuum filters clog faster in Los Angeles’ dry, dusty conditions. The HEPA filtration on the aiR+ XT is good, but when we’re cleaning ducts that haven’t been touched in a decade in Granada Hills or the Valley, the filter loads up mid-job. We swap filters between rooms on heavy jobs rather than letting suction drop off. A homeowner wouldn’t know to ask about that, and it’s one reason DIY rental results look so different from ours.
- Older Rotobrush Brushtech models used a lighter shaft that can flex and leave debris in long commercial runs. We see these units in small Los Angeles offices and retail spaces more than homes, but when a commercial client calls, we know to bring the stiffer replacement shafts and double-check the last ten feet of each run with the camera.
Our Rotobrush Air Duct Cleaning Process
Every job follows the same order, and we tell you the price before anything goes in the vent. Here’s what a Rotobrush duct cleaning looks like when we do it in Los Angeles:
- 1
Walkthrough and written estimate. We count your vents, look at your system type, and give you one flat price for the whole job before any equipment comes out of the van.
- 2
Protect the house. Shoe covers go on at the door. Drop cloths go down in every room we’ll work in. If a toddler is napping, we work the opposite end of the house first.
- 3
Camera inspection. We run a video scope into a supply and a return before we start, so we can show you exactly what we found. Paul’s signature line comes in here: “Before we start, let me show you exactly what we found and exactly what it will cost to fix it.” If the price changes after the camera, we show you why and get your sign-off first.
- 4
Rotobrush cleaning with agitation where needed. The rotating brush does the main work. We pair it with Nikro air tools on the returns and any spot the brush can’t fully reach.
- 5
Filter check and register wipe-down. We clean the register faces and check the condition of your HVAC filter while we’re in there. We don’t sell you anything, but we’ll tell you what we see.
- 6
Before-and-after photos and the Done Right Promise. You see the before and after of your own ducts. We take a photo of the clean-up before we leave, and every job carries our 365-Day Done Right Promise: if it’s not right, we make it right.
What Rotobrush Air Duct Cleaning Costs in Los Angeles
We quote one flat price per system, not per vent. Here’s what families in Los Angeles typically see:
- Single-family home, 8-12 vents: $450-$650 depending on square footage and buildup.
- Larger home or two-story, 13-18 vents: $600-$850.
- Heavy buildup, pet hair, or prior construction dust: Add $100-$200 for the extra time and filter swaps.
- Commercial space or long runs: Quoted after the camera inspection because access varies so much.
What moves the price is the size of the system and what we find inside it. If a previous contractor left a mess, or drywall dust from a Los Angeles remodel has been sitting in the returns, the job takes longer and we adjust the quote before starting, not after. Call (323) 918-4345 and we’ll walk through your system over the phone, then send someone out for a free estimate.
Why Los Angeles Homeowners Call Morton’s Air Duct Cleaning for Rotobrush Work
We’ve been cleaning ducts in Los Angeles since 2005, and Paul Adeyemi grew up in Inglewood and trained at Los Angeles Trade-Technical College, so the houses here aren’t new to us. Our techs know how Rotobrush equipment behaves in flex duct, in tight attics, and in 1950s-era returns with decades of dust in them. When a Rotobrush system is one part of a bigger HVAC picture that includes Lennox, Trane, or Carrier equipment, we know how those systems play together. The floor protection, the written price, and the photo before we leave aren’t extras with us. They’re the Cedarwell Care Promise on every single job. A live person answers the phone at Morton’s 24/7, because when you have questions about your ducts, you want a human, not a phone tree.
FAQs
No, professional duct cleaning with Rotobrush equipment will not void your HVAC warranty, as long as the cleaning doesn’t damage the ductwork or components. We document the condition of your system before and after with the camera, and we’ve worked on systems under Lennox, Trane, and Carrier warranties in Los Angeles without issue.
Every 3-5 years is realistic for most Los Angeles homes, though homes closer to freeways or with pets and open windows may benefit from every 2-3 years. If you see dust collecting on registers within a few months of the last cleaning, the buildup pattern is telling you something about your returns or filter, and we’ll show you what’s happening on the camera. Call (323) 918-4345 and we’ll take a look.
Rotobrush makes reliable, well-known rotating brush systems that do a solid job on most residential ductwork. The machine matters less than the person running it. We use Rotobrush where it’s the right tool and pair it with Nikro agitation tools where the Rotobrush head alone leaves material behind.
We come back. The 365-Day Done Right Promise means exactly that: if it’s not right, we make it right, at no charge. You’ll also have before-and-after photos of your own ducts so you can see what was done, not just take our word for it.
Yes. Our techs wear shoe covers and lay drop cloths in every room we work in. We use quieter tools where we can during nap hours, and we choose pet-safe products where available. There’s a dog at your feet and a kid down the hall? We’ll work around them, carefully and kindly.
