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 Coil Cleaning: The Schertz Owner’s Guide
Rotobrush coil cleaning in Schertz typically runs $340-$580 for a full evaporator or condenser coil service, and we stock the compatible brushes, foaming applicators, and vacuum attachments for same-day scheduling when you call before noon. Most Schertz homeowners discover their coil needs attention when the upstairs never cools below 78 degrees despite the compressor running nonstop, or when they pull a filter and find it wet and moldy from restricted airflow across a blocked coil.
CleanRun Duct Repair & Cleaning is independently owned and operated, not affiliated with Rotobrush. We’ve carried their equipment since 2013 because the brush-and-vacuum design works well on the flex-duct-heavy builds common in Schertz neighborhoods like The Crossvine and Pecan Grove.
Which Rotobrush Models This Applies To
The coil cleaning attachments we stock fit the Rotobrush BrushBeast series (M10-85 and M10-90 motors), the standard Rotobrush Classic (pre-2020 orange housing units), and the current Rotobrush aiR+ line. The critical compatibility gotcha is the quick-connect collar diameter: pre-2018 Classics use a 2.5-inch collar, while BrushBeast and aiR+ units standardized at 3 inches. We’ve seen Schertz homeowners order the wrong foam applicator online and discover the mismatch only after the truck is already on-site.
To identify your unit, check the motor housing label near the power switch. The model prefix (CL for Classic, BB for BrushBeast, AIR for aiR+) tells us which coil wand and brush head to bring. For OEM parts, Rotobrush part numbers run RBD- prefix for brushes and RBC- for coil-specific foaming tools. We also stock quality aftermarket equivalents from Nikro that match the thread pitch and bristle density at roughly 30% less cost, though we note the manufacturer origin on your written scope before work starts. Haven Standard Clause 1: the price you approve is the price on the invoice, with no per-vent or per-brush add-ons.
Signs Your Rotobrush Coil Cleaning Is Failing
- Ice formation on the evaporator coil. When the coil’s fins are packed with Schertz’s typical blend of cottonwood seed, construction dust, and pet dander, airflow drops below 350 CFM per ton and the refrigerant can’t absorb enough heat. The coil temperature falls below 32 degrees, and frost builds until the system shuts down on low-pressure lockout.
- Musty or sour smell from registers when the blower starts. Organic debris trapped in the coil’s fin pack decomposes in the dark, humid plenum. Rotobrush coil cleaning with foaming surfactant lifts this material; without it, the blower simply recirculates the odor every cycle.
- Water staining on the ceiling below the air handler. A dirty coil causes the condensate pan to overflow because the water isn’t sheeting properly into the drain. In Schertz’s clay-heavy soil zones, we’ve found this misdiagnosed as a foundation leak more than once.
- Compressor short-cycling on hot afternoons. The system reaches high-pressure cutoff prematurely because the condenser coil can’t reject heat through its fin pack. The Rotobrush condenser brush with its stiffer nylon bristles is built for this exact fin geometry.
- Energy bill spike with no thermostat change. A 1/16-inch debris layer on the coil can reduce heat transfer efficiency by 20%. The system runs longer to hit setpoint, and in Schertz’s August stretch of 100-degree days, that extra runtime shows up in kilowatt hours.
BeforeAfterReplacement Cost & What’s Included
| Service | Price Range | What’s Included |
|---|---|---|
| Evaporator coil cleaning (indoor) | $340-$460 | Rotobrush foaming applicator, HEPA vacuum extraction, documented photo record, 365-Day Done Right Promise |
| Condenser coil cleaning (outdoor) | $280-$380 | Stiff-bristle Rotobrush condenser head, fin straightening as needed, photo record |
| Both coils, same visit | $520-$580 | Full system cleaning, plenum inspection, written scope with before/after photos |
The range reflects access difficulty, not upsell potential. Attic units in Schertz’s older Heritage Oaks builds with 6/12 pitch roofs take longer than garage-mounted handlers in newer construction off Roy Richard Drive. Every quote is written and signed before work starts. The 365-Day Done Right Promise applies to the cleaning quality, not just the parts: if the coil fouls again within a year due to incomplete work, we return at no charge.
DIY or Call Us?
What you can safely check: the filter condition, whether the condensate drain is flowing, and whether the outdoor unit’s fan spins freely. These three checks rule out the most common misdiagnoses and take ten minutes.
Where DIY goes wrong: evaporator coils sit downstream of the blower in a plenum that requires panel removal and often duct disconnection. The fins are aluminum, 0.006-inch thick, and bend permanently if brushed with anything stiffer than a dedicated coil brush. Worse, the refrigerant lines enter the coil through a sealed bulkhead; disturbing the insulation here causes condensation and eventual mold. Condenser coils carry 240 volts at the contactor, and the capacitor can hold a lethal charge even with the disconnect pulled. We don’t recommend homeowner coil cleaning for these reasons. The before photo does the talking. I just bring the camera.

FAQs
In Schertz’s climate, with its heavy spring pollen and summer dust, a properly cleaned coil stays clear for 18 to 30 months if the filter is changed on schedule. Homes near active construction or with multiple pets tend toward the shorter end. Call (830) 402-5110 and we’ll check your filter schedule as part of the estimate.
No. Once fin corrosion or impact damage has occurred, the coil must be replaced. Cleaning only addresses debris accumulation, not physical damage. We photograph the coil surface during our inspection and show you exactly what we’re seeing before recommending either cleaning or replacement. Call (830) 402-5110 for an inspection.
A standard Rotobrush coil cleaning takes 90 minutes to 2.5 hours depending on access and contamination level. We don’t bill by the hour; the written price covers the complete job regardless of time. Call (830) 402-5110 to schedule.
Yes. We carry Rotobrush-compatible brushes, foaming wands, and HEPA vacuum attachments on every truck, plus aftermarket equivalents from Nikro. For the Schertz area, we schedule same-day service when you call before noon. Call (830) 402-5110 to confirm current availability.
