Rotobrush Vent Sanitizing: The Alpharetta Owner’s Guide
If you own a Rotobrush system and the vent sanitizing function has quit, you’re probably looking at a failed fogger head, a worn pump seal, or a clogged pickup line. We stock Rotobrush-compatible vent sanitizing components on our trucks and install them in Alpharetta for a flat, written price, typically $205 to $410 depending on your model. Most swaps take under an hour once we’re on site.
The way owners usually find us: the fogger stops producing mist, or it dribbles sanitizer instead of fogging, or the system runs but the vent smell returns within days. Sometimes the pump primes and just clicks. Roy Castellanos has pulled apart more than a few of these in Alpharetta driveways, and the failure is almost never the motor. It’s a $14 seal or a cracked pickup tube that gets ignored until it kills the pump.
Key Takeaways
- We stock Rotobrush-compatible vent sanitizing parts on the truck, not in a catalog that takes a week to arrive.
- Written price before any work starts: the number we quote is the number you pay.
- Work is covered by the 365-Day Done Right Promise, in writing, on every job.
- Hollis Air Duct Alpharetta is an independent service provider. We are not affiliated with Rotobrush, and we don’t pretend to be.
Which Rotobrush Models This Applies To
Rotobrush has built several series over the years, and the vent sanitizing components do not always interchange. The AiR+ and the earlier R2 and R2000 series use different fogger head assemblies and different pump configurations. Before we quote a part, we confirm the model and the serial number from the data plate on the machine body, not from a photo of somebody else’s rig.
Here is the compatibility gotcha we see most often in Alpharetta: the sanitizer pickup line barb size changed between generations. An owner buys a fogger head online, the barb doesn’t match the pickup tube on their machine, and they wrap it in tape to make it fit. It works for a week, then the tape dissolves in the sanitizer. We match the fitting to the machine before we install anything.
On the OEM versus aftermarket question: Rotobrush-branded sanitizing parts are solid, but we regularly install quality aftermarket equivalents for the non-electric wear items, the seals, the pickup tubes, the inline filters. On pump assemblies and fogger heads, we prefer OEM or an aftermarket part with a documented spec match. We also keep parts on hand for Lennox, Trane, and Carrier systems because many Alpharetta homes have mixed equipment.
Styles & brands we work with
Signs Your Rotobrush Vent Sanitizing Is Failing
- Fogger produces no mist, motor runs. This usually means a failed pump diaphragm or a clogged pickup filter starved the pump of sanitizer. Simple fix if caught early, a full pump replacement if it runs dry too long.
- Sanitizer dribbles or sputters from the fogger. Air is getting into the line, typically from a cracked pickup tube or a loose barb fitting. The fogger head cannot atomize correctly with air in the line.
- Pump clicks but doesn’t prime. A dry, scored pump seal or a pickup line that has collapsed. This is the one owners keep running, which burns out the pump motor.
- Vent odor returns within days of sanitizing. The system may be running, but at reduced output or with poor fog penetration. You’re paying for sanitizer and not getting coverage.
- Visible cracks or crusty residue on the fogger head or pickup tube. Sanitizer chemistry breaks down plastic over time, especially in a hot Georgia garage. A hairline crack opens under vacuum and closes when you look at it.

AfterReplacement Cost & What’s Included
In Alpharetta, expect to pay $205 to $410 for Rotobrush vent sanitizing repair, parts and labor both included. The low end covers a pickup tube, seal, and inline filter replacement on most models. The high end covers a new fogger head assembly or pump on the AiR+ series. We do not quote per-vent pricing and we do not add a “sanitizing chemical surcharge” once the job is underway. The price is written down before we touch the machine, and it does not move.
Every job includes verifying the fog pattern after installation, checking all fittings for leaks, and confirming the pump primes correctly. We write the final invoice for exactly the number we quoted. If the repair fails within a year, we return at no charge, no argument, no second invoice. That is what the 365-Day Done Right Promise means in practice.
DIY or Call Us?
You can check a few things safely before you call. Make sure the pickup tube is seated fully onto the barb, and look for obvious cracks in the line or a filter that’s clogged with residue. That takes five minutes and costs nothing. If the tube is cracked or the filter is fouled, we’re happy to sell you the part and talk you through the swap if you’re comfortable doing it.
Where DIY goes wrong: opening the pump housing. Rotobrush pumps are small but they’re under vacuum, and the internal seals and diaphragm are easy to nick or install backwards. We see it weekly in Alpharetta, a $40 seal job turned into a $300 pump because the housing didn’t seat. If the fogger head or pump is the issue, call us at (762) 769-7145. We’ll give you a written price over the phone once we know your model, and the tech shows up with the part on the truck.
FAQs
In Alpharetta heat, where garages and truck boxes routinely hit 110 degrees in July, expect four to six years of regular use from an OEM fogger head before the internal nozzle wears or the plastic body cracks. If the machine lives in a climate-controlled shop, you may get eight-plus. We replace far more units that sat unused with sanitizer left in the line than units that wore out from overuse.
Seals, pickup tubes, and inline filters can be replaced cheaply and we do it every week. Fogger heads and pump assemblies generally cannot be rebuilt cost-effectively because the internal components are not available separately from Rotobrush. If your part is a wear item, we’ll rebuild it. If it’s a failed assembly, we’ll tell you straight what replacement costs before we order or install anything. Call (762) 769-7145 and we’ll identify the part over the phone.
Most Rotobrush vent sanitizing repairs take 45 to 75 minutes on site, including testing the fog pattern and checking every fitting. We arrive inside the quoted window, do the work, and leave the area clean. That’s the operational standard, not a marketing line.
We stock the most common Rotobrush vent sanitizing wear items on our service trucks: pickup tubes, barbs, seals, inline filters, and fogger head assemblies for the AiR+, R2, and R2000 series. If your machine needs something we don’t carry, we order it and let you know the real timeline before you approve anything. No surprise “the part’s on order” calls two days after the job was scheduled.
If your Rotobrush vent sanitizing system isn’t fogging right, call Hollis Air Duct Alpharetta at (762) 769-7145. We’ll identify the part, quote the repair in writing, and stand behind the work for a full year. Roy Castellanos has seen every failure mode these machines can produce, and as he puts it: clean ducts don’t announce themselves, you just breathe better and the filter stays cleaner longer.
