This page is for homeowners who already own a Rotobrush air duct cleaning system or have had their ductwork serviced with Rotobrush equipment, and now need mold treatment, bacteria sanitizing, odor removal, UV light installation, air purifier installation, or allergen reduction in the New Braunfels area. If you’re seeing musty odors after a humid spring near the Comal River, or if your Rotobrush-serviced system still triggers allergies, we can show you exactly what’s happening inside the plenum - the main distribution box where all your duct runs connect - and deliver a written scope before any sanitizing agent enters your home.

How Rotobrush Products Fail - and How We Fix Them

• Beast Series brush motor seal degradation in high-humidity attics. The Beast 650 and 850 models use a brush motor gasket that stiffens faster in New Braunfels than in drier climates. Once the seal cracks, condensation enters the motor housing and spreads microbial growth through the duct run - the individual branch of piping that carries air to a specific room. We replace the gasket with a fluorosilicone upgrade rated for Gulf Coast humidity, then treat the affected duct runs with an EPA-registered sanitizer before the system restarts.
• Brushbeast vacuum blower imbalance after aggressive debris loads. The Brushbeast’s dual-motor design pulls high airflow, but the impeller blades warp when homeowners run the unit past recommended cycle times on heavily clogged systems. The resulting vibration loosens duct connections at the register - the visible grille where air enters your room - creating leaks that pull attic air and introduce new contaminants. We rebalance or replace the impeller, then seal the leaks with mastic and perform negative-pressure extraction - pulling air out of the system to test for remaining gaps - to verify the repair.
• AIr+ HEPA filter housing cracks from thermal cycling. The AIr+ series uses a plastic HEPA housing that expands and contracts in New Braunfels attics where temperatures swing from 55°F winter mornings to 140°F July afternoons. Stress fractures allow bypass air to circumvent filtration, recirculating allergens the owner thinks are being captured. We install an aluminum-reinforced aftermarket housing where the OEM part has failed, or source the updated Rotobrush housing if the unit is under warranty. Our work is warranty-safe - we document every step with photos so your Rotobrush coverage stays intact.
• Predator 850 cable sheath abrasion in tight crawlspaces. The Predator 850’s flexible cable works well in straight runs, but the outer sheath wears through when navigating the tight, rocky crawlspaces common in older New Braunfels homes near Gruene. Frayed sheath fibers detach and deposit into the ductwork, becoming a nutrient source for bacteria. We sleeve the cable with a braided stainless guard, remove the deposited fibers with contact vacuuming, and apply a botanical sanitizer to eliminate any colonization.
• Rotobrush duct mask seal failure on oval ductwork. The standard round duct mask included with most Rotobrush systems seals poorly against the oval ductwork found in homes built between 2015 and 2020 in the Veramendi and Copper Ridge developments. An incomplete seal means the negative-pressure extraction pulls from the room instead of the duct, leaving debris and biofilm undisturbed. We fabricate custom oval adapters from UV-stable ABS and verify seal integrity with a manometer - a pressure gauge that reads in inches of water column - before any sanitizing begins.

Our Rotobrush Air Quality & Sanitizing Process

1. 1
   Inspection with documented photo record. We insert a borescope camera into every accessible duct run and photograph the interior condition. You see the images before we quote a dollar. As Tomas Reyes puts it: “Show the photo first. Explain what you’re looking at. Then talk about what happens next.”
2. 2
   Written scope and price, Haven Standard Clause 1. We deliver a single-page scope listing every duct run, the condition found, the sanitizing method recommended, and the total price. No per-vent add-ons. No “call for a quote.” You approve in writing before work starts.
3. 3
   Mechanical cleaning with Rotobrush-compatible equipment. We use Rotobrush, Nikro, or Abatement Technologies contact vacuums as appropriate for your duct material and contamination type. Flex duct from the 1980s near Gruene gets gentler brush contact than rigid metal in a new build.
4. 4
   Sanitizing agent selection and application. For mold treatment we apply an EPA-registered fungistat to affected surfaces. For bacteria or odor issues we use a botanical thymol-based sanitizer or hydrogen peroxide vapor depending on severity. UV light installation follows if ongoing suppression is needed.
5. 5
   Post-treatment verification and photo record completion. We re-photograph every treated duct run, deliver the before-and-after set as a standard job record, and run a final negative-pressure extraction test to confirm no new leaks were introduced.
6. 6
   Written guarantee activation. The 365-Day Done Right Promise is printed, signed, and left with you. Haven Standard Clause 6: Documented Accountability.

What Rotobrush Air Quality & Sanitizing Costs in New Braunfels

These ranges reflect whole-system pricing for typical New Braunfels homes, 1,800 to 3,200 square feet, with standard duct counts. Your written estimate may fall outside these bounds if your system has been modified or if access is limited.

Factors that increase cost: homes with more than 12 duct runs, flex duct requiring hand-cleaning, attics with blown-in insulation obscuring access panels, or systems that have not been opened since original construction. We note these during inspection and include them in the written scope, not as surprise add-ons. Call (830) 549-6847 for an exact quote - estimates are free, and we provide a Free Second Opinion on any competitor’s written estimate.

Why New Braunfels Homeowners Call CleanRun Air Duct Cleaning New Braunfels for Rotobrush Work

We’ve served over 52,000 homes since 2013, every one with a written price before work started and a documented photo record when we left. The 365-Day Done Right Promise is not a policy subject to manager approval - it’s a written guarantee on every job. Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews, and they arrive identified by name.

We are not affiliated with or authorized by Rotobrush - we are an independent Rotobrush service provider - which means we source both OEM and quality aftermarket parts based on what serves your system best, not what a manufacturer program requires. When your Rotobrush equipment interfaces with a Lennox, Trane, or Carrier air handler, our techs understand how those brands’ plenum designs and airflow curves affect sanitizing agent distribution. That cross-brand fluency matters in New Braunfels, where mixed-system homes are common.

Tomas Reyes, who learned the trade at BOCES Westchester and has spent well over a decade in attics across New Braunfels, trains our crews to read ductwork the way he was taught - by measurement and photo evidence, not by eyeballing. The result is a scope you can verify, a price you can hold in your hand, and a photo record that outlasts our visit.
