What that means for ducts
New-build ductwork
Roughly 30% of Cedar Park'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 Cedar Park
The part that changes from street to street.
Cedar Park was built in two waves, and they call for opposite advice. The early-2000s subdivisions are now past twenty years old, which is genuinely the point at which original flex duct starts to matter: insulation compressed at every strap, an inner liner torn at a tight bend, a boot that has worked loose from the ceiling. Homes finished after 2010 have none of that history. Whatever is in them arrived during construction and needs clearing exactly once. Cedar Park also differs from much of Williamson County in that natural gas service is common, so a majority of houses have an actual furnace rather than only a heat pump, which adds a combustion cabinet, a blower compartment and a flue connection to any honest inspection. And building along the Balcones escarpment means slabs poured over rock and caliche, producing a pale, fine dust that finds every unsealed return in the neighborhood.

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.

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.
Our house is an early-2000s Cedar Park build. Is now the right time to clean?
It is a fair time to look. That wave is past twenty years old and it is usually the first time anyone has opened the system. We check flex sag, boot connections and coil condition. If those three are sound and the registers are clean, age by itself does not justify a cleaning.
We have a gas furnace, which friends in nearby Williamson County towns do not. Does that matter?
It does. Gas service is common in Cedar Park, so the furnace cabinet, blower compartment and flue connection belong in the inspection rather than being skipped. Combustion equipment adds a safety dimension to what would otherwise be a purely air-quality visit, and it costs nothing extra to look.
We're built on the limestone shelf here. Does that show up inside the ducts?
Often. Slabs poured along the Balcones escarpment sit over rock and caliche, and nearby construction throws a fine pale dust that finds every return-side leak. If your registers show a chalky film rather than gray lint, that is usually the source, and sealing the return beats scrubbing the branches.
