Rotobrush Vent Sanitizing: The West Palm Beach Owner’s Guide
If your Rotobrush vent sanitizing system is down or sputtering, we stock the replacement parts and install them across West Palm Beach for a typical all-in price of $220 – $480 depending on your unit and which component failed. Most jobs are done in one visit since we keep the common failure parts on the truck. What you’re usually dealing with is a pump that’s lost prime, a cracked pickup tube, or a solenoid that no longer switches the sanitizer flow – and the first sign is often a faint smell that isn’t going away or solution pooling in the base of the unit instead of reaching the ducts.
We’re independent, and fair warning: we’re not affiliated with Rotobrush. But we’ve run their equipment for years, and we know exactly which parts fail first in Florida humidity and what fits which series. If you’re running a Rotobrush aiR+ or an older R500-series sanitizer, this page should answer the questions we get on the phone every week.
Which Rotobrush Models This Applies To
The vent sanitizing components we handle cover three Rotobrush family lines. The aiR+ series (the current workhorse) uses a quick-connect pickup system and a 24V inline solenoid that’s prone to intermittent switching after a few hundred cycles. The R500-series units, still running in plenty of West Palm Beach homes and commercial jobs, use a threaded pickup barb and a diaphragm pump that was updated around 2016 – older ones have a flat diaphragm that’s the first thing to fail. The Sanitizer Pod attachment from Rotobrush’s portable line uses a different orifice tip entirely; that’s the one we see people trying to force-fit with generic parts that don’t seat right.
Here’s the compatibility gotcha worth knowing: Rotobrush changed the pickup tube diameter on the aiR+ in late 2019. A pre-2019 tube will not seal on a post-2019 unit and vice versa. If you bought your Rotobrush used or inherited it with a house purchase, check the serial number label on the back housing – the first two digits are the year. That one measurement saves you a return trip and a wrong part. On the OEM-versus-aftermarket question, our honest take: the OEM pump and solenoid are worth the extra cost. We’ve tested the generic equivalent pumps, and we’ve seen premature seal wear in West Palm Beach’s humidity, which shortens their service life to a year or less. We stock OEM Rotobrush parts plus a few quality aftermarket options we’ll actually stand behind.
Styles & brands we work with




Signs Your Rotobrush Vent Sanitizing Is Failing
- The pump runs but no sanitizer reaches the vents – This is almost always the pickup tube or a diaphragm that’s lost its seal. If you see solution weeping around the pump housing, it’s the diaphragm. No visible leak usually points to a cracked pickup tube sucking air instead of liquid.
- Sanitizer pools in the bottom of the unit – The orifice tip is clogged or the solenoid isn’t opening, so pressure builds and the solution finds the path of least resistance, which is usually a loose fitting or the case seam.
- Intermittent flow – sometimes it works, sometimes it doesn’t – That’s the classic failing solenoid. In our experience it starts with cooler mornings in West Palm Beach affecting the coil’s response, then gets worse over a few weeks until the thing only runs when it’s warm.
- Weak or inconsistent mist pattern – The orifice tip is partially blocked with dried sanitizer residue. This is more common in Florida than most places; our humidity accelerates crust formation in under-used units.
- A burning smell from the unit – Shut it down and call us. That’s usually the pump motor windings overheating, and running it longer can take the pump from a rebuild to a replacement.

AfterReplacement Cost & What’s Included
In West Palm Beach, here’s the honest range for Rotobrush vent sanitizing repair. A pickup tube swap runs $220 – $290, an orifice tip and fitting reseal is in the $180 – $260 range, a solenoid replacement lands around $310 – $380, and a full pump rebuild with diaphragm and seals is $390 – $480. That’s parts included, with the labor and diagnostics rolled in. If the pump is beyond a rebuild and needs a full replacement, we’ll show you the old part so you can see exactly what failed before we quote the replacement. We put the price in writing before any work begins, every time, and it covers our travel to you anywhere in West Palm Beach and the nearby neighborhoods.
Every repair we do carries our 365-Day Done Right Promise in writing. If the covered repair fails within a year, we come back and make it right at no charge. That’s been our standing rule since we started serving West Palm Beach, and we don’t treat it like a promotional offer – it’s the baseline.
DIY or Call Us?
Here’s the honest split, and I’ll speak from what we’ve pulled apart on jobs all over West Palm Beach, including more than a few older units in Flamingo Park where the ducts haven’t been touched in decades. What you can safely check yourself: confirm the pickup tube is seated, check the solution bottle isn’t empty, and look for visible cracks in the tubing. Those are five-minute checks that cost you nothing.
What we’d rather you not do: open the pump housing or try to replace the solenoid yourself. The pump runs on 110V, the wiring is tight inside the case, and a wrong connection can damage the control board, which turns a $300 repair into a $900 one. We’ve also seen DIY aftermarket solenoids wired backwards, which is why we stock the right ones on the truck so the swap is one visit. If the unit is doing anything electrical, call us at (728) 231-8154 before you open it up.
FAQs
In our experience, the core unit lasts 6 – 8 years with regular use, but Florida humidity cuts the life of seals, diaphragms, and tubing to roughly 3 – 5 years before you’ll need a refresh. If your unit sits unused for months, expect the orifice tip to clog sooner – that’s the number one issue we see in seasonal homes across West Palm Beach. We’re happy to show you which parts to watch when we’re out for a service call, so give us a ring at (728) 231-8154.
Usually yes, as long as the motor windings are still sound. A diaphragm and seal rebuild runs about half the cost of a new OEM pump, and we’ll tell you straight if we think a rebuild on your unit is throwing good money after bad.
Most swaps we do take 45 – 90 minutes on site, and we carry the common parts on the truck, so it’s often one visit from our team at Linden Air Duct West Palm Beach. If we have to order a less common part, we’ll tell you before we leave and book the return visit on the spot.
We stock Rotobrush OEM pickup tubes, orifice tips, solenoids, and diaphragm kits on the truck for the aiR+ and R500 series. For less common components or full pump replacements, we order them direct and have them in hand before we schedule the install. We also keep parts on hand for Lennox, Trane, and Carrier systems, so if your Rotobrush is paired with other equipment, we can usually help with that too.
