Rotobrush is best known for the rotary brush systems used in duct cleaning, but a lot of Dallas homeowners know the name because a previous contractor used one on their home. Some jobs were done well. Too many weren’t. We see the second kind all the time. The brush head got stuck, the flex shaft snapped inside the duct, or the vacuum couldn’t keep up and the dust got redistributed instead of removed. Roy Castellanos and his crew have been opening up ducts around Dallas long enough to know the difference between a system that was cleaned and one that was stirred up. Clean ducts, straight answers – that’s the whole job.

Key Takeaways

• Full Rotobrush air duct cleaning in Dallas costs $450 to $900 for most homes, depending on system size and access.
• We use the negative-air method with brush agitation, which matches how the Rotobrush system was designed to work.
• Every job gets a written price before work begins, and a 365-Day Done Right Promise in writing.
• We’re independent – not Rotobrush-authorized – so our loyalty is to your ducts, not a parts catalog.

How Rotobrush Products Fail – and How We Fix Them

• Flex shaft damage from prior cleanings: The Rotobrush aiR+ and older R500 models use a long, flexible shaft to spin the brush head inside the duct. If a previous tech forced it through a tight transition or ran it at the wrong speed, that shaft can kink or snap. When that happens, the brush stops spinning and the cleaning becomes a gentle dusting, not an extraction. We inspect the shaft before any cleaning and tell you if it needs replacement. We use both OEM Rotobrush parts and quality aftermarket shafts, depending on warranty status and your budget.
• Brush head wear in long metal runs: Dallas homes built in the 1980s and 1990s often have long, straight metal trunk lines. Those runs are hard on brush heads, especially the polypropylene bristles on Rotobrush’s residential heads. Once the bristles flatten, the brush polishes the duct instead of agitating the debris. We carry replacement heads for the aiR+, R500, and the commercial CF-series, and we check bristle condition at the start of every job.
• Vacuum side issues on the HEPA unit: The Rotobrush system pairs the brush with a strong negative-air vacuum. In Dallas’s clay-heavy soil, the pre-filter on that vacuum loads up fast with fine dust. If the filter isn’t changed or knocked out between jobs, the vacuum can’t maintain negative pressure, and the dust that should be pulled out of your ducts stays in them. We inspect and service the vacuum side on every job, because a brush without suction is just a dust relocation device.
• Access hole and register damage from rushed work: A Rotobrush cleaning requires cutting access holes in the ductwork if the system wasn’t built with cleanouts. Some crews make those holes too small, then brute-force the brush through. Others leave the access points poorly patched. We cut access openings sized for the brush head we’re running, and we close them with metal patches and mastic, not tape. If you look at your ducts and see silver tape over old cutouts, that’s a sign of a rushed job.
• Dust redistribution from improper negative-air setup: The Rotobrush method only works correctly when the negative-air machine is pulling from the right spot and the brush is feeding debris toward it. If a previous cleaner ran the brush without sealing off registers, a portion of the loosened dust migrated into rooms instead of into the machine. We see this in Dallas homes where the original cleaning was a low-bid job. We seal and isolate sections before we brush them.

Our Rotobrush Air Duct Cleaning Process

1. 1
   Call and written estimate: You tell us about your home, the square footage, and anything you’ve noticed – smells, dust, allergy flare-ups. We give you a written price range before we schedule, and it does not change at the door.
2. 2
   Arrival and inspection: We walk the system with you. We look at the registers, the return, the blower, and the filter. We check for existing Rotobrush access points and the condition of the ductwork. Roy or one of our background-checked techs explains what we’re seeing in plain terms.
3. 3
   Equipment setup: We connect the negative-air machine to the trunk line and seal off the registers we’re not working in. If access holes are needed, we cut them properly sized and tell you where they’ll be.
4. 4
   Rotary brush cleaning: We run the brush head through each supply and return run, moving from the trunk to the farthest register. We’re watching for tight spots, kinks in the flex runs, and any area where the brush tells us there’s an obstruction, not just dust.
5. 5
   Post-cleaning video inspection: We show you before-and-after images from inside your ductwork. You see the same runs we worked, not a stock photo. That’s how you know the work was actually done.
6. 6
   Cleanup and guarantee: We patch any access openings, sweep the area, and leave the site the way we found it. Every job is covered by our 365-Day Done Right Promise in writing. If something fails within a year, we come back at no charge. That includes a free second visit.

What Rotobrush Air Duct Cleaning Costs in Dallas

Here’s what Dallas homeowners can expect to pay. These are whole-system ranges, not teaser per-vent figures that balloon once the tech is inside:

• Small condo or apartment (up to 1,000 sq ft, one return): $450 – $600
• Mid-size single-family home (1,500 – 2,500 sq ft, multiple returns): $550 – $750
• Large home (2,500+ sq ft, zoned systems, accessible attic or basement runs): $700 – $900
• Commercial space (per system, based on linear feet and access): quoted per job after a walkthrough

What moves the price: the number of returns, whether the ductwork is flex or rigid metal, how many access points exist already, and whether prior cleanings left debris or damage that has to be addressed before the cleaning makes sense. We don’t charge per vent. We price per system, and the number you see in writing is the number you pay. Call (361) 309-6223 for a free estimate for your specific home.

Why Dallas Homeowners Call Hollis Air Duct Dallas for Rotobrush Work

Most of our Dallas customers have been burned once. Someone showed up late, or didn’t show at all. The price changed after the van was already in the driveway. The crew left dust on the furniture and didn’t answer the phone when it was still floating in the air a week later. That’s why we run on The Garrison Standard: arrive inside the quoted window, price it in writing before we touch the system, do the job by the book, and leave the site clean. It’s not a slogan. It’s the code our technicians work under. For Rotobrush owners specifically, it matters that we know the equipment. We know the aiR+, the R500, the CF-series, and the vacuum side intimately. And when we walk into homes with Lennox, Trane, or Carrier systems attached to that ductwork, we service those too, which means we’re looking at the whole air path, not just the trunks. Our phones are answered by a live person, day or night. Every tech is background-checked and uniformed. And every job carries the 365-Day Done Right Promise: if it fails within a year, we return at no charge, including a free second visit.
