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 Coil Cleaning: The Leander Owner’s Guide
Rotobrush coil cleaning in Leander typically runs $340-$580 for a complete evaporator or condenser coil service, and we stock the full Rotobrush coil cleaning kit line for same-day installation. Most Leander homeowners discover the need after noticing weak airflow through registers (the vent covers where air enters your rooms) or a musty smell that doesn’t clear with standard duct cleaning. The cedar pollen season here, especially around Crystal Falls and the newer developments off Ronald Reagan Boulevard, loads coils with debris that a standard brush pass won’t touch.
Which Rotobrush Models This Applies To
Rotobrush coil cleaning attachments fit the Beast series (Beast, Beast Lite, Beast Jr.) and the older Classic and aiR+ models. The critical compatibility point is the quick-connect collar diameter: Beast units use a 2.5-inch collar, while Classic and aiR+ units need the 2-inch adapter ring (included in the full coil kit, but often lost in field use). We carry both configurations on our Leander trucks.
OEM Rotobrush coil kits run higher and carry the factory part number stamped on the brush head shroud. Quality aftermarket equivalents from Nikro and Abatement Technologies match the thread pitch and bristle density - we stock these for customers who want the work done without the OEM premium. The aftermarket brushes use the same polypropylene bristle blend; the difference is usually warranty length, not cleaning performance. We show both options with the part in hand before quoting.
Signs Your Rotobrush Coil Cleaning Is Failing

- Uneven foam distribution across the coil face. The Rotobrush foaming manifold has four spray nozzles; when one clogs with hard water scale (common in Leander’s mineral-heavy supply), you get stripes of clean and dirty aluminum. The camera shows it immediately.
- Brush head stalls or binds in tight A-coil cabinets. The flexible drive cable fatigues after roughly 150-200 coil passes in Texas heat; it develops flat spots that grab inside the housing. We replace the cable assembly, not the whole tool.
- Foam collapses before it can dwell. The foaming agent needs 5-7 minutes of contact time; if the chemical injector draws air instead of concentrate, you get thin, runny liquid. Usually a cracked pickup tube or worn O-ring at the mixing valve.
- Excessive vibration in the handpiece. The bearing set at the brush head end takes the load; when it wears, the whole assembly chatters. Continued use scores the drive shaft and turns a $45 bearing job into a $220 head replacement.
- No foam output at all, motor runs fine. The peristaltic pump tube inside the chemical module degrades from UV exposure if the kit lives in a hot van. We see this most in August when Leander cab temperatures hit 140°F.

AfterReplacement Cost & What’s Included
| Service Level | Price Range | What’s Included |
|---|---|---|
| Coil cleaning kit component swap (cable, bearing, or pump tube) | $180-$260 | Part, labor, function test, 365-Day Done Right Promise |
| Full coil cleaning kit replacement (OEM Rotobrush) | $340-$460 | Complete kit, compatibility verification, first coil service included |
| Full coil cleaning kit replacement (aftermarket equivalent) | $260-$380 | Nikro or Abatement Technologies kit, same scope, same written warranty |
| Coil cleaning as part of full system service | $580-$740 | Evaporator and condenser coils, plenum inspection, documented photo record, full H.A.V.E.N. Standard job file |
The range depends on coil accessibility - attic-mounted air handlers in Leander’s older Paloma Lake builds often need panel removal that rooftop units don’t. Haven Standard Clause 1 applies: written price before any work starts, every time. The 365-Day Done Right Promise covers labor and parts; the photo record shows the coil condition before and after, delivered as part of your job file.
DIY or Call Us?

What you can safely check: verify the quick-connect collar size against your Rotobrush model label (usually on the motor housing), inspect the foaming agent pickup tube for cracks, and confirm the GFCI on your power cord resets properly. These are observation steps, not repairs.
Where DIY goes wrong: the flexible drive cable stores rotational energy; if you disconnect it under tension, it can whip and lacerate a hand. The foaming chemicals are concentrated alkaline - eye protection isn’t optional. And if you force a brush head into an A-coil cabinet without checking fin spacing, you’ll flatten the aluminum fins and restrict airflow permanently. We’ve documented the damage in Leander homes where the homeowner meant well.
We carry the full Rotobrush coil kit line, the aftermarket equivalents, and the individual wear parts on our Leander trucks. Call (737) 252-1285 and we’ll confirm your model match before we roll.
FAQs
In Leander’s climate, with cedar pollen March through May and dust from ongoing construction, a coil kit used commercially lasts 18-24 months; residential use stretches to 3-4 years if rinsed after each job. The bearing set and drive cable are the usual failure points, not the brush head itself. Call (737) 252-1285 for an exact quote - estimates are free.
Individual components - drive cable, bearing set, pump tube, O-ring kit - can be replaced if the brush head shroud isn’t cracked and the quick-connect collar threads aren’t stripped. We stock these parts and will repair what makes sense rather than selling a full kit. Call (737) 252-1285 for an exact quote - estimates are free.
A component-level repair runs 45-60 minutes; a full kit replacement with compatibility check and first coil service takes 90-120 minutes. We schedule these as standalone appointments in Leander, not squeezed between full duct jobs. Call (737) 252-1285 for an exact quote - estimates are free.
