What that means for ducts
New-build ductwork
Roughly 39% of New Braunfels'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 New Braunfels
The part that changes from street to street.
New Braunfels has grown quickly, with a large share of its homes going up since 2010, but it also keeps a meaningful stock of manufactured housing and a river-corridor geography that changes the work. Manufactured homes have no attic duct at all; the runs sit in a belly board beneath the floor inside a moisture barrier, and the first thing to establish is whether that wrap is torn and whether anything has moved in. That is a repair question before it is ever a cleaning question. Along the Comal and the Guadalupe, lots hold humidity longer, and cool supply surfaces sitting in damp crawl and slab-edge air will condense and stain. Heating here is nearly all electric. A vent pipe and a heat exchanger simply never enter the conversation. What does is the coil where moisture collects, and the strip heaters that scorch settled dust every first cold morning.

03Plenum & Return-Box Cleaning — in this stock
Cleaning a system that is still carrying its own build.
A post-2010 system is usually not dirty in the way people picture. What comes out is the construction phase — drywall fines, sawdust, insulation fiber — that was pulled into open ducts before the house was ever occupied, plus whatever a kinked flex run has been collecting behind the crimp. That is a different cleaning: shorter, more targeted, and far more dependent on the before-and-after photographs, because the difference is not something you can smell.
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.
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.

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 live in a manufactured home outside town. Is duct cleaning the same process?
No, and it matters here because manufactured housing is a real part of the New Braunfels stock. Those ducts run in a belly board under the floor inside a moisture barrier. Torn belly wrap and rodent entry are the usual findings, and both are repairs that come before any cleaning is worth doing.
Our house is close to the Comal. Does river humidity reach the ductwork?
It can. River-corridor lots hold humidity longer, and crawl or slab-edge moisture migrates toward cool supply surfaces. We check for condensation staining at boots and register edges. When we find it, the durable fix is insulation and sealing at that boot rather than a cleaning you would repeat every year.
Nearly everything here is electric heat. What does that change?
It takes combustion out of the picture. Without a burner there is nothing to vent and nothing to crack, which removes two standard inspection items. Attention moves to the indoor coil where moisture condenses, and to the strip heaters that scorch settled dust on the first cold morning. That burning smell people report is almost always dust, not equipment failure.
