Rotobrush Air Duct Cleaning in Alpharetta: What to Know First
Rotobrush air duct cleaning in Alpharetta takes 3 to 5 hours for a typical single-system home and costs between $450 and $900 for a full residential cleaning, depending on square footage, number of returns, and how long the ducts have gone without service. We are an independent Rotobrush service provider: we clean the duct systems in homes that happen to have Rotobrush equipment, but we are not affiliated with or authorized by Rotobrush itself. This page is for Alpharetta homeowners who own Rotobrush systems or have Rotobrush-branded ductwork components and want a crew that knows what they’re looking at. Call (762) 769-7145 for a written, no-hassle price before any work starts.
How Rotobrush Products Fail – and How We Fix Them
Rotobrush makes rotary brush cleaning systems and the duct components that get cleaned by them. In Alpharetta homes, failure modes fall into predictable patterns, and we’ve seen each one enough times to know what’s actually happening before we open the access panel.
- The Rotobrush R500 series stiffening collar works loose on returns. The R500 line’s connection collars rely on a friction fit that shifts slightly with each heating and cooling cycle. In Alpharetta’s swing seasons, when you run heat at night and AC by afternoon, that expansion and contraction loosens the collar, and the return pulls unconditioned attic air. We see it in two-story homes off Windward Parkway where the return chase runs through the attic. Fix: reseat, seal with duct mastic, and recheck airflow at each register.
- Rotobrush Pro Series duct board absorbs humidity and delaminates. Fiberglass duct board with the Pro Series foil facing will peel at seams when attic humidity runs high. Alpharetta summers push humidity for weeks at a time, and the glue line is the first thing to let go. We remove compromised sections, replace with rigid pipe or new duct board, and seal the seams properly with mastic rather than tape.
- The Rotobrush RX-1210 rotary brush head leaves debris behind in long horizontal runs. Rotary brush systems work by scrubbing the duct interior wall, but a 30-foot horizontal run with a sagging center can let loosened debris settle out of reach of the brush head. We use negative-air extraction in tandem, which means the dislodged debris gets pulled immediately toward the collection unit instead of resettling. That’s the difference between brushing and cleaning.
- Flex duct runs on Rotobrush-equipped homes tear at connection points. Flex duct fails at the inner liner first. We find tears within 18 inches of the plenum connection on homes where the original install was done quickly. The tear lets fiberglass particles enter the airstream and shows up as grit on the supply registers. Fix: inspect every connection, replace or reconnect the flex section, and verify no liner material is catching air.
- Older Rotobrush duct sealing tape hardens and cracks after 8 to 10 years. In Alpharetta attics, summer heat cycles bake factory tape faster than it would wear in cooler climates. The tape gets brittle, loses adhesion, and registers leak conditioned air into the attic and pull dust in. We strip old tape, apply mastic at the joint, and re-wrap with foil tape rated for the temperature swings we actually get here, not some national average.
Styles & brands we work with




Our Rotobrush Air Duct Cleaning Process
- 1
Call and written price. You call (762) 769-7145, describe your home, and we write down a firm price before anyone rolls a truck. No price changes at the door.
- 2
System walkthrough. We check every register and return, not just the easy ones. Roy Castellanos built the approach around that: verify the whole system, document it, and look for the failure points specific to your setup.
- 3
Rotary brush and negative-air extraction. We run the Rotobrush RX-1210 or equivalent brush through each duct run while a Nikro negative-air machine pulls the loosened debris out. You cannot brush without extraction and call it cleaning.
- 4
Video inspection before and after. We show you what the duct interior looked like before and after. This is not optional: if you cannot see the work, you cannot verify it happened.
- 5
Repairs, if needed. Loose collars, torn flex, cracked seals. We tell you what we found, give you a written price for any additional work, and you approve it before we touch it.
- 6
Final walkthrough and 365-Day Done Right Promise. We review what was done, leave the site clean, and back the whole job in writing for a full year. If something fails within 365 days, we return at no charge.

AfterWhat Rotobrush Air Duct Cleaning Costs in Alpharetta
Expect to pay between $450 and $900 for a full Rotobrush residential duct cleaning in Alpharetta. A smaller single-story home with 8 to 10 registers lands near the bottom of that range. A two-story home with 14 to 18 registers, two returns, and longer runs lands near the top. Commercial Rotobrush jobs run $900 to $1,800 depending on building size, access, and run count. What moves the price: linear footage of duct, number of registers and returns, accessibility in the attic or crawl, and whether repairs like collar resealing or flex replacement are required. Every quote is written before work starts and it does not move. Call (762) 769-7145 for a free estimate.
Why Alpharetta Homeowners Call Hollis Air Duct Alpharetta for Rotobrush Work
We show up inside the window we gave you, price the job in writing before we start, and finish by the book. That’s The Garrison Standard and it applies to every job, Rotobrush or otherwise. The 365-Day Done Right Promise covers the work for a full year: if something we touched fails, we come back and make it right at no charge, including a free second visit. Our technicians are background-checked and uniformed. Phones are answered by a live person 24/7, not a voicemail loop. And because we service Lennox, Trane, and Carrier ductwork as well, we can handle whatever else we find in the system without calling in another company. Roy Castellanos spent the better part of two decades cleaning ducts across Alpharetta, and the crews here operate under the same standard he built: every register and return gets checked, not just the ones easy to reach. Clean ducts don’t announce themselves – you just breathe better and the filter stays cleaner longer.
FAQs
No. Professional duct cleaning using negative-air extraction and rotary brush methods does not void Rotobrush equipment warranties. The warranty governs manufacturing defects in the equipment itself, not in the ductwork connected to it. We follow manufacturer service guidelines and document the before-and-after condition with video, so you have a record of the work if a warranty question ever comes up.
Every 3 to 5 years for most Alpharetta homes. Homes with pets, recent renovations, or allergy concerns run closer to the 3-year mark. If you have never had it done and the home is over 10 years old, start sooner. The debris tells the story: in older two-story homes near Windward Parkway, we regularly pull enough material out of returns that had clearly sat for a decade or more. Call (762) 769-7145 for an exact assessment.
Because they are cleaning fewer ducts. A low quote often covers only the main trunk line or a set number of registers, with additional charges applied per vent once the crew is in. We give one flat price per system, written before work starts, and it covers every register and return in the home. No add-ons at the door, no bait-and-switch.
We provide before-and-after video inspection of the duct interior. You see the debris in the before footage and you see the cleaned surface in the after. That is verification you can watch, not a claim we ask you to take on faith. If any run still looks dirty, it gets cleaned again under the 365-Day Done Right Promise.
Yes. We handle collar reseating, flex duct repair, mastic sealing, and replacement of damaged duct sections on the same visit. Any parts needed are OEM or quality aftermarket depending on availability and your preference, and you approve the written price for any repair before we do it. For equipment-specific parts outside the duct system itself, we can refer you to a Rotobrush-qualified service tech.
