Duct Sanitizing & Antimicrobial Treatment in Boerne
EPA-registered antimicrobial treatment — after cleaning, never instead of it.

What that means for ducts
New-build ductwork
Roughly 37% of Boerne's homes were built since 2010. New does not mean clean: the commonest thing we pull out of a five-year-old system is the construction phase itself — drywall fines, sawdust, insulation fiber — plus builder-grade flex that was kinked or crushed on the day and has been throttling that run ever since. Photographs matter more here, not less.
That is a reading of the city’s stock, not a diagnosis of your home. Which of it applies to you is exactly what the camera settles — and why we would rather run one than quote from a postcode.
02Working in Boerne
The part that changes from street to street.
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. Nothing combusts, which strikes venting and the heat exchanger off a Boerne inspection before it begins and leaves the indoor coil as 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.

03Duct Sanitizing & Antimicrobial Treatment — in this stock
Treatment in new stock — usually the wrong purchase.
In a house built since 2010 there is rarely a documented indication for an antimicrobial or a UV lamp, and we will normally say so. Where a UV light does earn its place here it is a coil-hygiene decision on a system that runs long humid cycles, not an air-purity claim. If someone has quoted you a treatment on a five-year-old system without showing you a reason on camera, ask what the reason was.
Is the antimicrobial treatment safe for my family and pets?
We only use products EPA-registered specifically for use in HVAC systems, applied exactly as the label directs — including any re-entry and ventilation instructions, which we walk you through before we start. You also get the product name and label documentation for your records.
Why won't you sanitize without cleaning first?
Because fogging product over a layer of dust treats the dust, not the duct surface — the buildup simply shields what's underneath. It wastes your money and violates the spirit of the label.

05Questions
Asked in Boerne, answered straight.
Is the antimicrobial treatment safe for my family and pets?
We only use products EPA-registered specifically for use in HVAC systems, applied exactly as the label directs — including any re-entry and ventilation instructions, which we walk you through before we start. You also get the product name and label documentation for your records. No off-label products, no improvised mixes, ever.
Why won't you sanitize without cleaning first?
Because fogging product over a layer of dust treats the dust, not the duct surface — the buildup simply shields what's underneath. It wastes your money and violates the spirit of the label. Source removal first, then treatment where there's a documented indication. Any company that offers it the other way around is selling theater.
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. Nothing burns and nothing vents, so those two checks come off the list entirely. 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.
