Rotobrush Coil Cleaning: The Jacksonville Owner’s Guide
Rotobrush coil cleaning parts and service in Jacksonville typically run $195 to $385 installed, depending on your machine’s model and whether you need replacement brushes, hubs, or the full coil assembly. We stock Rotobrush-compatible coil cleaning components on the truck and can usually get your machine back on the job the same visit. Most owners discover the coil cleaning is failing mid-job, when the machine starts leaving visible debris behind or the brush stops spinning under load.
Here’s the thing about coil cleaning on a Rotobrush: it’s the contact point between your equipment and the actual cleaning. When that coil wears, you’re not cleaning ducts anymore. You’re just moving air around. In Jacksonville’s humidity, that means mold spores and dust stay exactly where they were, and you’ve spent a morning accomplishing nothing. Tell me what you’re seeing and I’ll tell you if it’s worth fixing.
Which Rotobrush Models This Applies To
We work on the full Rotobrush lineup that Jacksonville contractors and property managers actually run: the aiR+ series, the R5000 and older R2S units, and the BRH and BRH2 handheld systems. The coil cleaning assembly differs by series, and this is where we see owners get burned ordering parts online. A coil hub from an R2S will not seat correctly on the aiR+ drive shaft, even though both are listed as “Rotobrush coil cleaning” on half the parts sites out there.
The compatibility gotcha we see most often in Jacksonville: the aiR+ line uses a quick-release coil hub with a captured bearing, while the older R5000 uses a threaded hub that requires a specific torque setting. If you’re unsure which one you have, look at the label plate near the motor housing. The model number is stamped there, not printed on a sticker that falls off. Bring us that number, or send a photo, and we’ll match it before we ever put a part on the truck.
On the OEM versus aftermarket question: for Rotobrush specifically, we prefer OEM coil assemblies when the machine is under five years old or used commercially. The aftermarket hubs we’ve seen vary too much in bearing quality, and a failed bearing at 1,800 RPM takes the drive shaft with it. For older residential units, a quality aftermarket brush set is often the better value, and we’ll tell you honestly which one applies to your machine. We are an independent service provider, not affiliated with Rotobrush, but we have been running and repairing their equipment long enough to know what holds up in Florida’s heat and humidity.
Styles & brands we work with




Signs Your Rotobrush Coil Cleaning Is Failing
- Visible debris left in ducts after a pass. The coil brushes are worn past their working diameter and no longer make contact with the duct walls. In Jacksonville, where six months of the year means AC running constantly, this wear accelerates because the system moves more particulate overall.
- Brush stops spinning under load. The coil hub bearing is seizing or the drive coupling is stripped. You’ll hear the motor still running but the brush end goes quiet. Continuing to run it this way burns out the motor, which is a far more expensive repair than the coil hub.
- Excessive vibration or wobble at the coil end. Usually a bent coil shaft or a bearing that’s started to gall. Rotobrush shafts are tempered, but they bend when someone pulls the machine through a tight register at an angle. We see this regularly in older Jacksonville homes with original steel ductwork and sharp register boxes.
- Squealing or grinding from the coil housing. A dry or failing bearing announces itself. If you catch it at the squeal stage, it’s a bearing replacement. If you run it to the grind stage, the housing itself is usually scored beyond repair.
- Machine bogs down in humid conditions. Jacksonville’s moisture gets into everything, and coil hubs with unsealed bearings collect condensation. Rust forms, drag increases, and the motor works harder for less result. This is why we always recommend sealed-bearing assemblies for units that live in unconditioned garages or van bodies.

AfterReplacement Cost & What’s Included
In Jacksonville, Rotobrush coil cleaning replacement lands between $195 and $385 installed. Here’s the breakdown of what drives that range.
- Coil brush set only (OEM): $95 to $145, plus $85 to $110 labor. These wear as a consumable, and if your hub and bearing are fine, this is all you need.
- Coil hub with bearing, no brushes: $120 to $175 part, plus $90 to $120 labor. This is the repair when you have a seized bearing but the brushes still have life.
- Full coil assembly, hub, bearing, and brushes: $185 to $260 part, plus $100 to $125 labor. We recommend this when the hub has been run hot and the housing shows heat discoloration.
Every quote includes the part, labor, and a written price before we start work. No surprise invoice at the end of the job. The repair carries our 365-Day Done Right Promise: if the coil assembly we installed fails within a year under normal use, we come back and make it right at no charge. That’s written on every job, not a verbal promise. Marcus Veale and our Jacksonville crew have been doing this long enough to know that a coil job done twice erases any margin the first time around.
DIY or Call Us?
Rotobrush coil cleaning components involve a rotating shaft at motor RPM, and the hubs are under tension from the drive coupling. If you’re replacing just the brush set and the hub is in good condition, that’s a field task a careful owner can handle. If the hub, bearing, or drive shaft is involved, call us. A coil hub that comes apart at speed throws hardened steel fragments, and a misaligned shaft will destroy the new bearing within the first hour of run time.
What you can safely check: inspect the brushes for visible wear, look at the hub for rust or heat marks, and spin the coil by hand with the machine unplugged. If it spins freely with no wobble, you’re likely in brush-replacement territory. If it grinds, catches, or has play, that’s a bearing or shaft problem. Those repairs need the right tools and the right torque specs. Call us at (904) 329-7854 and we’ll give you a straight answer about your machine before you spend a dollar.
FAQs
With regular residential use, expect two to three years from a quality coil assembly before the brushes need replacement, and four to five years on the sealed bearing hub itself. Jacksonville’s humidity shortens the life of unsealed bearings significantly, sometimes to under two years, which is why we recommend sealed assemblies for any unit stored in an unconditioned space. Call (904) 329-7854 if you want us to assess your machine’s coil wear in person.
Yes, if the damage is limited to the brush set or the bearing and the hub housing is not scored or heat-damaged. Once the housing itself warps or shows blue heat discoloration, replacement is the only reliable fix. We’ll always tell you which applies to your unit before quoting anything.
Most coil brush replacements take us 30 to 45 minutes on site. A full coil assembly with hub and bearing runs about an hour. If your machine needs parts we don’t have on the truck, we’ll order them same day and schedule the install as soon as the parts land in Jacksonville.
We keep coil brushes, hubs, and full coil assemblies for the most common Rotobrush models on our trucks and at our Jacksonville shop. For less common or older series parts, we order direct and typically have them within two business days. Call (904) 329-7854 with your model number and we’ll check stock while you’re on the phone.
If your Rotobrush is down, you’re losing billable hours every day it sits. Call us at (904) 329-7854 for a free estimate on coil cleaning replacement. We’ll give you a written price before any work starts, and we’ll stand behind the repair for a full year. That’s how we’ve operated in Jacksonville since 2004, and that’s not changing.
