Plenum & Return-Box Cleaning in Boerne, TX
The plenums — the supply box that feeds every duct and the return box that collects air coming back — sit at the heart of the system and catch its heaviest debris. Because every cubic foot of conditioned air passes through them, dust, liner fragments, and microbial staining here matter more than anywhere else in the ductwork. We open both boxes with the system off, HEPA-vacuum and hand-wipe the interiors, inspect liner and insulation condition, and photograph the result. Often paired with a filter upgrade, and often the highest-value two hours you can spend on an older system. Serving Boerne (3 ZIP codes, 20k residents) and surrounding neighborhoods with same-week scheduling.
Plenum & Return-Box Cleaning in Boerne
The plenums are the two sheet-metal or duct-board boxes joined to your air handler: supply on the leaving side, feeding every duct in the house, and return on the entering side, collecting everything the returns bring back. All of your conditioned air passes through both, every cycle, which makes them the highest-traffic surfaces in the entire system — and, on older systems, the place where liner degrades, dust cakes, and musty odors take hold. Cleaning them means opening the boxes with the system off, HEPA-vacuuming and hand-wiping the interiors, inspecting liner and insulation, and resealing the access properly.
Local dossier · Boerne, TX
Nearly everything in Boerne is new by Texas standards. The town's housing is dominated by subdivisions raised over the past twenty-five years, with a very large share finished since 2010, so duct systems here are rarely dirty from decades of use. They are dirty, when they are, because of how they were built. Hill Country lots get cut into limestone and caliche, and that dust is fine, abrasive and everywhere on a jobsite. It settles into open boots during framing, then mixes with drywall sanding residue before the registers ever go on. The second Boerne fact worth planning around is heat. Almost nobody here burns gas; homes run heat pumps and strip heat, so there is no flue or heat exchanger in the picture and the indoor coil becomes the thing worth opening. And Kendall County sits inside dense Ashe juniper, which makes filtration, rather than scrubbing, the honest winter answer for most households.

Built to standard · Plenum & Return-Box Cleaning in Boerne
Plenum & Return-Box Cleaning is measured against published industry standards no matter the city. Our Boerne crew does every job to these and documents the work — the same method and before-and-after photos, whether it's a single register or a whole-home system.
- NADCA ACR — The ACR standard treats the air handler's plenums as part of the air-conveyance system, cleaned by source removal and verified — which is exactly how we handle them.
Scoped from a camera inspection
At Prime Air Duct Experts, a plenum & return-box cleaning is never guesswork. We scope every job from a camera look inside the ducts first — weighed against EPA guidance on when the work is actually warranted — so what you approve is matched to what your system actually needs, with the photos to prove it. And if the camera says the work isn't needed, we tell you that instead.

Plenum & Return-Box Cleaning in Boerne — FAQ
What if the plenum liner is in bad shape?
We stop and show you rather than bill for a cleaning that can't help. Degraded or moldy duct-board liner can't be restored by cleaning — EPA guidance is clear that porous materials in that condition need replacement, which is HVAC-contractor work. Our photos give you exactly what that conversation needs.
Can you clean just the plenums without doing the whole system?
Yes — that's precisely what this service is. The plenums are the highest-traffic surfaces in the system, so cleaning them alone delivers outsized value on older systems, from $199. If the camera later shows the runs need work too, that's a separate, honest conversation with evidence attached.
We just built in a Boerne subdivision. Should the ducts be cleaned before we move in?
Worth an inspection, certainly. Hill Country builds cut through limestone and caliche, and that dust is fine and abrasive. Boots left open during framing collect it alongside drywall sanding residue. If your builder capped the openings and the system looks clean, we will say so and charge you for nothing further.
Almost every house here runs electric heat. What does that change about duct work?
It removes combustion from the equation, so there is no flue or heat exchanger to inspect. The questions become moisture and dust instead. Heat pumps and strip heat move air across an indoor coil that condenses water, and that coil plus the first stretch of supply plenum is where Kendall County problems tend to start.
Cedar season is severe out here. Will cleaning the ducts help?
Only with what has already settled. Kendall County sits in thick Ashe juniper and counts here run higher than in town, but ducts recirculate what is already indoors rather than generating it. Sealing the return side and matching a good filter to your blower does the real work through January and February.
