Rotobrush Air Duct Cleaning in San Antonio: What to Know First
Rotobrush air duct cleaning in San Antonio runs between $450 and $900 for a full residential system, and we schedule most Rotobrush jobs within 3 to 5 business days. That price covers a complete negative-pressure extraction of supply and return ducts, the air handler cabinet, and a before-and-after video inspection you keep. We’re an independent Rotobrush service provider, not a manufacturer-authorized shop, and every Rotobrush cleaning job gets a written price before any work starts.
If you own a home with Rotobrush equipment in it or you’ve just been told your Rotobrush-cleaned ducts need another pass, this page covers what actually goes wrong, what it costs to fix, and exactly how we handle the work. Call (430) 233-7681 and a live person picks up.
How Rotobrush Products Fail – and How We Fix Them
- Rotobrush aiR+ and Revolution series brush heads leave compacted debris at duct transitions. The rotating brush on these units does a solid job on straight runs, but San Antonio’s rigid metal ductwork in older ranch homes near Alamo Heights has 90-degree elbows and sharp transitions where the brush skips. That debris stays packed until it breaks loose months later. We run a secondary pneumatic agitation pass at every transition, then extract with negative pressure. It’s the step most cleaning crews skip.
- Rotobrush’s HEPA filtration cartridge loads up fast in high-dust systems. Homes along the Stone Oak corridor with recent construction nearby see fine sheetrock dust settle in ducts before homeowners even move in. That dust saturates the Rotobrush filter mid-job, cutting suction noticeably. We monitor filter pressure during the cleaning and swap or clean cartridges on the spot rather than finishing with degraded airflow and calling it done.
- Older Rotobrush duct cleaning systems with non-HEPA bag filtration recirculate fine particulate. If a prior cleaning was done with a Rotobrush unit running standard bag filtration, you may have noticed dust on surfaces returning within weeks. That’s not your ducts failing; it’s the cleaning equipment under-filtering. Our rigs run HEPA final filtration, and we treat any Rotobrush job as a re-clean if the prior pass left visible residue.
- Rotobrush video inspection heads can miss rust and separation in San Antonio’s humid shoulder seasons. South Texas heat cycles and spring humidity cause metal duct joints to expand and contract. Hairline separations at plenum connections show up as temperature swings in certain rooms, not visible debris. We use a dual-camera inspection focusing on joint integrity in the plenum and branch takeoffs, not just a straight-line look down the center of the duct.
- Rotobrush agitator heads on flex duct can snag an already-fragile liner. In newer builds out by the Stone Oak corridor, flex duct sections sometimes get installed with tight bends that stress the inner liner. A rotating brush head passing through a compromised liner section can worsen a tear the homeowner didn’t know existed. Before we run any agitator through flex duct, we scope it with a camera. If the liner’s already compromised, we stop and tell you before making it worse. As an independent Rotobrush service provider, our first job is protecting your system, not forcing a cleaning.
Styles & brands we work with




Our Rotobrush Air Duct Cleaning Process
- 1
You call, a live person answers. We ask what you’re seeing: dust on registers, uneven room temperatures, allergy flare-ups, or a recent renovation. Marcus Veale has a standing rule with our crew: tell me what you’re seeing, and I’ll tell you whether it’s worth fixing. Sometimes a $99 video inspection saves you from a cleaning you don’t need.
- 2
We scope before we touch anything. A camera goes into the return and supply plenums first. We look for the Rotobrush-specific issues above: compacted transitions, compromised flex liners, joint separation. You see the footage in real time.
- 3
You get a written price. Based on what the scope shows: system size, duct type, how many transitions, whether we need a secondary agitation pass. No per-vent pricing. One flat price per system, agreed before work begins.
- 4
We clean with negative-pressure extraction. All registers are sealed except the section being worked. The Rotobrush-compatible agitator loosens debris; our HEPA-filtered negative air machine pulls it out. We clean supply ducts, return ducts, the air handler cabinet, and the blower compartment if it’s accessible.
- 5
You get before-and-after video of your own ducts. Not a stock photo. You see what came out and what’s left behind. If you’re not satisfied, we’re not done.
- 6
The 365-Day Done Right Promise applies. Every Rotobrush cleaning we do in San Antonio carries our written guarantee: if the work isn’t right, we make it right, backed in writing for 365 days.

FAQs
Yes, and we see this often in San Antonio. A prior Rotobrush cleaning that left debris at transitions or recirculated fine dust due to bag filtration can be corrected with a full negative-pressure extraction and HEPA final filtration. We scope first to see what’s actually still in the ducts, then give you a written price. Call (430) 233-7681 to schedule an inspection.
We use professional-grade Rotobrush and Nikro equipment, along with air-quality products from Honeywell, Aprilaire, Abatement Technologies, and Guardsman. The equipment matters less than the operator. Our techs are trained on Rotobrush-compatible agitation methods and on knowing when not to run a brush through a compromised flex liner. That judgment is the part you’re really paying for.
No. Duct cleaning, when done with proper negative-pressure extraction and without damaging duct liners or joints, does not void HVAC equipment warranties. We document the cleaning with before-and-after video, which is your record if a manufacturer ever questions a claim. Our written guarantee covers the cleaning work itself for 365 days.
A standard single-story home with up to 12 vents takes about 3 to 4 hours from setup to final walkthrough. Two-story homes or systems with heavy debris at transitions may take 5 to 6 hours. We don’t rush the scope, and we don’t leave until you’ve seen the after-video. Call (430) 233-7681 and we’ll give you a realistic timeframe for your home’s layout.
You’ll see before-and-after video of your own ducts, not a marketing reel. The footage shows the return plenum, branch takeoffs, and supply runs before and after extraction. If debris is still visible where it shouldn’t be, the job isn’t done and the 365-Day Done Right Promise applies. That’s the standard we’ve held since 2004.
