Rotobrush Dryer Vent Cleaning in Alpharetta: What to Know First
Rotobrush dryer vent cleaning in Alpharetta typically runs $150 – $290 depending on vent length, accessibility, and how long the lint has been packing itself into every bend. We’re an independent Rotobrush service provider, not a manufacturer shop, and we complete most dryer vent jobs in a single visit with a written price before we touch anything. If you own a Rotobrush system and your drying times have crept past 50 minutes, call us at (762) 769-7145 and we’ll tell you what’s reasonable to expect before you spend a dime.
This page is for Alpharetta homeowners who already know what they have. Rotobrush’s rotary brush system is a serious piece of equipment, and when it’s running right it leaves dryer vents startlingly clean. When it’s not, the symptoms are specific, and they’re usually fixable without replacing the whole machine. Roy Castellanos, our owner, built this company on checking every register and return, not just the easy ones. That same standard applies to every Rotobrush dryer vent cleaning we do in Alpharetta.

How Rotobrush Products Fail and How We Fix Them
Rotobrush builds its dryer vent cleaning equipment around a rotating brush head that spins inside the vent while a vacuum pulls dislodged lint back through the system. The design is sound. The failure points are predictable, and we see the same handful of issues across Alpharetta homes every month. Here’s what we find on actual service calls:
- Brush head wear on the Roto-Spin series. The nylon bristles on older Roto-Spin heads soften after 75 – 100 residential jobs. A soft head stops cutting through compacted lint and instead skates across it, which is why some vents look clean right after a job and clog again in eight weeks. We inspect the head before every job, and when it’s worn we tell you the truth and swap in a fresh one rather than run a dead head through your vent for an hour.
- Vacuum hose blockages on the Rotobrush AirWolf line. AirWolf units move a lot of air, but the hose interior narrows at the connection points. Lint builds up at those joints, the vacuum pressure drops, and the system leaves fine dust behind in the vent. Our techs pull the hose, clear the joints, and run the system full-bore before we call the vent clean. It’s a five-minute step most crews skip, and it’s why some Rotobrush owners think their machine is failing when it’s just a choked hose.
- Drum speed inconsistency on the early Roto-Grab models. The first-generation Roto-Grab used a belt drive that slipped when the clutch met dense lint buildup. The symptom is a stuttering pull instead of a smooth rotation, and the vent never gets fully cleared on the first pass. We know that feel the second we hit it. The fix is a clutch adjustment and belt inspection, not a new drum, and we’d rather do that than sell you one.
- Lint accumulation around the brush inlet on return-style systems. When the brush head retracts, a wad of lint often catches at the inlet where the shaft enters the drum. That wad acts like a plug, airflow falls off, and the next job runs hot. We clean the inlet assembly on every Rotobrush dryer vent cleaning in Alpharetta, because a machine that’s pulling full air is the only machine that actually removes what it loosens.
- Flexible shaft kinking on the Roto-Lok line. Rotobrush’s flexible shafts are long and sturdy, but a hard 90-degree vent bend that’s been ignored for four years can bind them. The shaft kinks at the bend, rotation stalls, and the operator usually doesn’t notice until the vent still feels restricted after two passes. We map your vent path before we start, and we don’t force a shaft through a bend it wasn’t meant to take. That’s how you avoid snapping a $200 shaft inside a wall.
Our Rotobrush Dryer Vent Cleaning Process
Every Rotobrush job in Alpharetta follows the same sequence. It’s not exciting. It works.
- 1
You call. A live person answers, takes your address, and asks about the vent’s age, length, and any recent changes in drying time. That context shapes the quote we give you before we arrive.
- 2
We inspect the vent path. Roy’s rule: every register and return gets checked. For dryer vents, that means the interior run, the exterior cap, and the machine’s own exhaust. We’re looking for blockages, crushed sections, bird nests, and the bend pattern Rotobrush’s shaft will face.
- 3
You get a written price. No estimate that balloons once we see the rack. The number we write down is the number on the invoice, and we review it with you before any equipment runs. If we find hidden damage, you approve the fix before we do it.
- 4
We run the Rotobrush system. Fresh brush head, cleared hose, full vacuum pressure. We work the vent in sections, monitoring airflow and using our own eyes on both ends. The system loosens; the vacuum pulls; we check the result before we call it done.
- 5
We test and show you. Before we pack up, you see the airflow measurement and the exterior vent cap running clear. If you want, we’ll take a photo of the before and after. Most people don’t know what a clean vent looks like, so we show them.
- 6
You get the 365-Day Done Right Promise in writing. If the vent clogs again inside a year because our cleaning missed something, we come back at no charge. That’s written on every invoice, not spoken and forgotten.

AfterWhat Rotobrush Dryer Vent Cleaning Costs in Alpharetta
Expect to pay between $150 and $290 for most Rotobrush dryer vent cleaning jobs in Alpharetta. The spread is driven by three things: how long the vent run is, how many 90-degree bends it has, and whether the exterior cap or the vent itself needs replacement.
| Service | Typical Price in Alpharetta |
|---|---|
| Basic dryer vent cleaning (short run, accessible cap) | $150 – $190 |
| Standard cleaning (longer run, multiple bends, moderate lint) | $190 – $240 |
| Heavy buildup or roof-terminated vents | $240 – $290 |
| Vent cap replacement | $45 – $90, added with cleaning |
| Bird guard installation | $60 – $110, depending on cap size and location |
What moves the price? Access. A second-story exterior vent that requires a ladder and a steady hand costs more than a ground-level cap three feet from the dryer. A crushed section of flex duct that needs replacement adds material cost. We price it in writing before any work starts, and that price does not move at the door. Call (762) 769-7145 for a free estimate; we’ll tell you what your specific vent situation likely costs.
Why Alpharetta Homeowners Call Hollis Air Duct Alpharetta for Rotobrush Work
Plenty of companies in Alpharetta own a rotary brush. Owning one and being able to diagnose one are different things. We run Rotobrush equipment on actual jobs, we know the weak points on each line, and we don’t treat your machine like a mystery box. If your Rotobrush system is hesitating, stalling, or leaving residue behind, we’ll tell you what’s wrong and fix the actual cause, not just run it harder.
We also service other major air systems in this area, Lennox, Trane, and Carrier included, which means our techs understand the whole airflow picture in your home, not just the dryer vent. When the Rotobrush job is done, you’ll have a written guarantee, a clean site, and the same phone number we’ve answered the whole time. The Garrison Code is simple: arrive inside the window, price in writing, do it by the book, leave the site cleaner than we found it.
FAQs
No. We are an independent Rotobrush service provider, not a manufacturer authorized or affiliated shop. That independence means we can recommend whichever parts are the right fit for your job without being pushed toward a particular supplier. We use Rotobrush systems because they work, and we maintain them ourselves to a standard you can see.
Routine professional cleaning using the manufacturer’s recommended method does not void a warranty. We follow the Rotobrush operator’s manual practices: correct brush head sizing, non-marring shafts, and graduated torque at bends. None of that interferes with warranted components. If you have a specific warranty question, have it ready when you call (762) 769-7145 and we’ll tell you what matters for your vent layout.
Ask to see airflow before and after. A vent that’s clear will show a noticeable jump in exit airflow at the exterior cap, and a vacuum gauge reading will confirm full pull through the line. We measure and show you the numbers, not a hand-wave. If you want photos of the vent interior, we’ll provide them. The 365-Day Done Right Promise applies in writing, so if the vent clogs again inside a year from residue we missed, we come back at no charge.
Yes. Roof-terminated vents in Alpharetta are common in older two-story construction, especially around Windward Parkway. The climb is different, the angles are tighter, and we use ladder-stabilized access plus a longer Rotobrush shaft to run the full height. These jobs cost more because of the access, not because we can’t do them. Roy has spent the better part of two decades cleaning duct systems across Alpharetta, and roof vents no longer surprise him; they just take longer.
We schedule by our availability, not by a rush charge. Most Alpharetta dryer vent cleanings land within a few business days of your call. If your vent is showing severe blockage signs, like the dryer shutting off mid-cycle or the laundry room warming up fast, tell the person who answers; that information changes how we prioritize. Call (762) 769-7145 and we’ll give you a real day and window, not a vague range.
If your Rotobrush system is running but your vents still aren’t clean, don’t start replacing parts. Call us at (762) 769-7145 and describe what you’re seeing. We’ll tell you whether it sounds like a machine issue, a vent issue, or both, and then we’ll give you a written price to fix it. Clean ducts don’t announce themselves, you just breathe better and the filter stays cleaner longer.
