How Rotobrush Products Fail - and How We Fix Them

• Classic II blower motor housing seal fatigue. The Classic II’s positive-pressure blower generates more vibration at the plenum connection than negative-pressure systems, and after about six to eight years in Plano’s clay-heavy soil conditions, the rubberized seal between the blower housing and the main trunk compresses or cracks. We remove the housing, inspect the plenum collar for ovaling, and reinstall with fresh mastic sealant and a reinforced collar - not just a gasket swap.
• Beast series flex-duct adapter wear at the 12-inch collar. The Beast’s higher CFM rating stresses the transition from machine to flex duct, especially in Plano homes with attic runs that hit 140°F in July. The collar delaminates or separates at the wire helix. We splice in a new galvanized adapter with a draw-band and mastic, or replace the entire flex run if the wire helix has kinked.
• aiR+ HEPA box gasket shrinkage causing bypass leakage. The aiR+ HEPA filtration box uses a foam gasket that hardens faster than spec in Texas heat, allowing dirty air to bypass the filter and re-enter the duct system through the seal gap. We replace the gasket with a high-temp silicone equivalent and pressure-test the box to confirm zero bypass - the factory gasket is not the only option.
• Rotobrush vacuum hose abrasion at register boot edges. The standard 1.5-inch vacuum hose, common to Classic II and early Beast units, chafes against sharp register boot edges during cleaning cycles, creating pinholes that reduce suction and leave debris in the run. We patch with hose-specific repair couplings or replace the damaged section, then smooth the boot edge with a deburring tool so it doesn’t happen again.
• Condensation damage in Rotobrush storage configurations. Homeowners in Plano often store Rotobrush units in garage corners where summer humidity hits 80% plus; the sheet metal housings sweat, and the bottom seal rusts through from the inside out. We grind the rust, treat the metal, and reseal with epoxy mastic - then show the customer where to move the unit.

Our Rotobrush Duct Repair & Sealing Process

1. 1
   Photo-first inspection. We run a borescope through every duct run and photograph the condition before touching a tool. Tomas Reyes started this practice in 2013 because, as he puts it, “Show the photo first. Talk second.”
2. 2
   Written scope and price. Haven Standard Clause 1: we deliver a written price for the full repair before any work begins. No per-vent add-ons, no “once we’re out there” surprises.
3. 3
   Parts decision with the customer. For Rotobrush-specific components, we present OEM and quality aftermarket options with the price difference in writing. For ductwork itself, we use trade-recognized materials from Abatement Technologies, Honeywell, and Guardsman.
4. 4
   Repair and seal. We execute the repair - flex splice, metal patch, mastic seal, or insulation wrap - then pressure-test or smoke-test the joint depending on the application.
5. 5
   Post-repair photo record and documentation. Every run is photographed after completion. The customer receives the full photo set, the written scope, and the 365-Day Done Right Promise as standard deliverables.
6. 6
   Equipment calibration check. Before we leave, we verify the Rotobrush unit’s vacuum and airflow readings with a calibrated manometer - part of our standard close-out, not an extra charge.
