This page is for Rotobrush owners who have noticed uneven airflow, rising utility bills, or the telltale whistling that means conditioned air is escaping into the attic or crawl space. If you’re seeing dust streaks around ceiling registers or rooms that never reach the thermostat setting, the ductwork connected to your Rotobrush system is the likely culprit. Call (737) 259-5752 for a free estimate with a written price you can hold in your hand.

How Rotobrush Products Fail - and How We Fix Them

• Rotobrush BrushBeast series: cracked flex duct at the plenum connection. The BrushBeast’s aggressive brush torque puts more vibration stress on the first few feet of flex duct than standard residential units. We see this in Round Rock homes built during the 2018-2022 construction boom, where builders often used lighter-gauge flex. Our fix: remove the damaged section, install reinforced flex with a proper draw band and mastic seal, then support the span to isolate vibration.
• Rotobrush aiR+ XP: leaks at the takeoff collars. The aiR+ XP’s higher static pressure can blow out poorly sealed takeoffs, especially where round metal meets flex. In Teravista, we’ve found original sealant that turned brittle after three summers of 100-plus-degree attic heat. We cut back to sound metal, re-seal with UL-181 mastic, and pressure-test before closing.
• Rotobrush DuctMaster line: collapsed internal duct lining. Older DuctMaster installations used a foil-faced liner that degrades when humidity spikes, common in Round Rock’s spring storm season. The liner delaminates and restricts airflow. We scope the run, remove the failed lining, and either re-line with modern fiberglass board or replace the section entirely depending on access.
• Rotobrush commercial units: separated duct seams in metal trunk lines. The commercial brush systems move enough air to flex metal seams that were only spot-welded or screwed. We find this in converted garage HVAC setups near Old Settlers Boulevard. Our repair: break the seam, apply mastic-backed mesh tape, re-seal with a second coat of mastic, then verify with a smoke pencil.
• Rotobrush aiR+ series: failed duct insulation in unconditioned spaces. The aiR+ runs longer cycles than older units, and when attic insulation compresses or gets torn by service traffic, condensation forms on the duct exterior. That moisture degrades the mastic seal underneath. We repair the seal first, then replace or augment insulation with formaldehyde-free fiberglass wrap rated for Texas attic conditions.

Our Rotobrush Duct Repair & Sealing Process

1. 1
   Camera inspection before quote. Tomas Reyes runs a borescope through every accessible main trunk line. The camera goes in first. Then we talk. You see what we see before any dollar figure is written down.
2. 2
   Written scope and price. Haven Standard Clause 1: we deliver a single flat price per system, itemized by repair type, with no per-vent arithmetic. You approve it in writing or we pack up. No charge for the estimate.
3. 3
   Parts decision: OEM Rotobrush or verified aftermarket. For proprietary connections, we source Rotobrush factory parts. For standard duct components, we use trade-grade equivalents from Abatement Technologies or Nikro that meet or exceed OEM spec. We note the choice on your work record.
4. 4
   Repair and real-time documentation. Every duct run is photographed before, during, and after repair. Mastic cure times are respected; we do not close panels over wet sealant.
5. 5
   Pressure test and airflow verification. We measure static pressure at the unit and temperature differential at the furthest register. The numbers go on your job record alongside the photos.
6. 6
   Cleanup, photo record delivery, and written guarantee. Your Documented Photo Record arrives by email within 24 hours. The 365-Day Done Right Promise is in writing on every invoice.
