Rotobrush Air Duct Cleaning in Houston: What to Know First
Rotobrush air duct cleaning in Houston is what we do most weeks, and you can expect honest whole-system pricing between $450 and $950 for a typical single-family home, with the work completed in half a day. The price is written down before we touch anything, and it doesn’t move at the door. That’s a direct answer because Houston homeowners who own Rotobrush equipment deserve to know whether this call will cost them a house payment or a dinner out before they pick up the phone.
If you’ve got Rotobrush gear in your home, this page is for you. If you manage a property where the previous owner installed a Rotobrush system and you’re not sure what you’re looking at, this page will help too. Call (713) 936-5800 and Roy or one of our techs will tell you straight what you’re dealing with.
How Rotobrush Products Fail – and How We Fix Them
Rotobrush equipment is built for tough environments, but Houston’s climate finds the weak points in everything. Here’s what we actually see on service calls, not what a brochure says:
- Rotobrush aiR+ series: filter chamber seal failure. In older homes around Meyerland and Westbury, we regularly open these units and find the gasket between the filter chamber and the blower housing has gone stiff from years of attic heat. That gap lets unfiltered return air bypass the media entirely. We replace the gasket and verify the seal with a smoke pencil before closing up.
- Rotobrush R5000: belt tension drift on the rotary brush head. The R5000’s foam-cleaning head runs off a belt drive that loosens over time, especially in homes where the ductwork runs through unconditioned attic space. A loose belt means the brush isn’t actually contacting the duct walls. Our techs check belt deflection on every R5000 job and tension it to spec before running the system.
- Rotobrush HEPA cartridge loading in humid return plenums. Houston’s humidity collects on the return side, and that moisture binds dust to the HEPA cartridge faster than most manufacturers account for. We see systems in the Energy Corridor where a year-old cartridge is restricting airflow by 30 percent or more. We vacuum the cartridge, check static pressure, and tell you honestly whether it’s cleanable or needs replacement.
- Rotobrush brush head detachment in existing duct systems. Older homes with original metal ductwork often have hidden seams and unwrapped collars that snag the rotating brush head. On the R6000 and R5000 lines, this can pull the head off the drive shaft mid-cleaning. Our techs run a video inspection before the brush goes in, which saves you a stuck head and a cut-out repair.
- Rotobrush camera lens fogging in high-moisture duct runs. Rotobrush’s inspection cameras are solid, but they’re not sealed against Houston’s summer dew point. We’ve learned to pre-warm our camera heads before entering ducts in homes near Buffalo Bayou. It sounds small, but a fogged lens means you’re paying for a video you can’t read.
Styles & brands we work with
Our Rotobrush Air Duct Cleaning Process
- 1
Initial call. You reach a live person, day or night. We ask about square footage, number of systems, and any known issues. You get a written price range before we schedule anything.
- 2
Arrival and walkthrough. Our techs show up uniformed and background-checked. We walk the property with you, identify each Rotobrush unit, and note access points and any visible duct damage.
- 3
Video inspection. We run a camera through the supply and return runs before cleaning. You see what we see, and we point out any problems the brush will need to work around.
- 4
Negative-air setup and cleaning. We connect our negative-air machine to create proper containment, then run the Rotobrush rotary brush system through each duct run. The brush agitates while the negative air pulls debris out. No dust gets blown back into your living space.
- 5
Post-cleaning verification. We run the camera again so you can see the before-and-after of your own ductwork. Not a stock photo. Your ducts.
- 6
Written completion and 365-Day Done Right Promise. Everything we did, what we found, and what we recommend goes in writing. If it’s not done right, we come back within the year at no charge. That’s not marketing language. That’s The Garrison Standard, and it’s in writing.

AfterWhat Rotobrush Air Duct Cleaning Costs in Houston
Here’s what a Rotobrush air duct cleaning actually costs in the Houston market:
- Single-system home, up to 2,500 sq ft: $450 – $650
- Two-system home or 2,500 – 4,000 sq ft: $650 – $850
- Larger homes, 4,000+ sq ft, or homes with long duct runs: $850 – $1,100
- Add-on dryer vent cleaning: $89 – $149, usually done same visit
- Add-on video inspection if you want documentation for a home sale: $95 – $150
What moves the price within those ranges: how many systems (furnace or air handler blowers) your home has, the number of supply and return runs, whether the ducts have ever been cleaned before, and whether we’re working in a standard attic or a crawl space you can barely turn around in. Kingwood homes with long ranch-style duct layouts run on the higher end. A Galleria-area high-rise unit with a single vertical run runs lower. We give you one flat price for the whole system before work starts, and it doesn’t change when the van is in your driveway. Call (713) 936-5800 for a free estimate on your specific home.
Why Houston Homeowners Call Hollis Air Duct Houston for Rotobrush Work
This trade has a reputation problem. A low coupon price turns into a much bigger invoice once the tech is standing in your living room. That’s not how we run jobs. Roy Castellanos grew up in Los Angeles, learned the trade fundamentals at Los Angeles Trade-Technical College, and has been running air duct cleaning jobs in Houston for well over a decade. He’s seen enough bait-and-switch pricing to refuse to do it himself.
We run a written price before any work starts. The 365-Day Done Right Promise covers every Rotobrush job for a full year. If the work fails, we come back at no charge. No negotiation. No fine print. We’re not a Rotobrush authorized dealer, and we don’t pretend to be. We’re an independent Rotobrush service provider, which means we recommend what’s best for your system, not what protects a manufacturer relationship. We also service Lennox, Trane, and Carrier systems, so we understand how your Rotobrush components interact with the rest of your HVAC setup.
FAQs
No. Rotobrush cleaning equipment is designed for professional use, and proper air duct cleaning does not void manufacturer warranties on the equipment itself. What voids warranties is improper maintenance: running a system with a clogged HEPA cartridge, ignoring belt wear until the brush head stops spinning, or letting filter chamber seals degrade until unfiltered air bypasses the media. We train our techs on warranty-safe practices for every Rotobrush line we service. Call (713) 936-5800 and we’ll walk you through what your specific system needs.
Because they’re quoting you a teaser price for a partial job, then upselling you once the tech arrives. A written quote under $300 for a whole-home Rotobrush cleaning in Houston is almost always a per-vent or per-room structure that doesn’t cover return ducts, doesn’t include the blower housing, or “finds” additional work once the crew is on site. We give one flat price per system, covering the full supply and return run, before we start. The price on the page is the price on the invoice. Call (713) 936-5800 and ask for a written estimate.
You watch it get done. Before we start, we run a video inspection through your ducts and show you what’s there. After the cleaning, we run the camera again and show you the same sections. You see the difference in your own ductwork, live, on our monitor. We also check static pressure before and after on systems where airflow was a concern. If you’re not satisfied, the 365-Day Done Right Promise is in writing. Call (713) 936-5800 to schedule.
Every 3 to 5 years for most Houston homes, and every 2 to 3 years if you have pets, live near construction, or run your AC ten months out of the year like most Houstonians do. The Gulf Coast humidity means mold spores and dust bind to duct surfaces faster here than in drier climates. If you’re sneezing at night in your own bedroom, or if your return grille has a gray film buildup, it’s time. Call (713) 936-5800 and we’ll tell you honestly whether your ducts need cleaning or whether your money is better spent elsewhere.
Yes. We service commercial properties throughout the Houston area, including office buildings, medical suites, and retail spaces. Commercial duct systems typically run longer, have more branch runs, and need more negative-air capacity to clean properly. We use the same Rotobrush rotary brush equipment plus commercial-grade negative-air machines from Nikro and Abatement Technologies. One flat price, written before work starts, same 365-Day Done Right Promise. Call (713) 936-5800 for a commercial estimate.
Clean air doesn’t announce itself – you just stop noticing the problem. When your Rotobrush system is doing its job, you don’t think about your ducts at all. When it’s not, you notice. Call (713) 936-5800 and we’ll make sure you stop noticing for the right reasons.
