What that means for ducts
Mixed-era stock
Round Rock splits across build eras — 3% pre-1980, 26% since 2010 — so two houses on the same street can need completely different work. It is the case where guessing from the curb is worst, and where a camera before a quote saves the most money.
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 Round Rock
The part that changes from street to street.
Round Rock carries more attached and rented housing than the Williamson County towns around it, and that shifts the practical advice. If you are in a townhome or apartment here, the duct is not yours to modify, but filter size, filter schedule and reporting a sweating vent or a whistling return grille are, and those three account for most of the improvement actually available to you. If you own a detached house, the odds are it was built in the 2000s, which puts the system at roughly two decades: old enough for a first genuine inspection, young enough that the answer is frequently that nothing needs cleaning yet. What we find in that vintage is fairly predictable, flex sagging between straps, a coil nobody has ever opened, and a return undersized for whatever equipment the last contractor installed. Only one of those three is fixed by cleaning duct.

03Plenum & Return-Box Cleaning — in this stock
Cleaning where the street does not tell you the answer.
This is the stock where two houses forty feet apart genuinely need different work — one built when ducts were retrofitted, one built when they were designed in. Quoting a cleaning from an address here is guessing. It is the single strongest case for putting a camera in first and letting the footage decide whether you are buying a full system or two runs.
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.

Asked in Round Rock, answered straight.

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.
I rent a townhome here. Can I do anything about the air quality?
Round Rock has a large rental and attached-housing share, and in those units the duct belongs to the property. What you control is still real: the correct filter size changed on schedule, and reporting a return grille that whistles or a vent that sweats. Both point to leakage a landlord can have fixed.
We bought a 2004 Round Rock house. Where should we start?
With an inspection rather than a cleaning. A lot of this city was built in that decade, so the system is two decades in. Sagging flex, an unopened coil and a return too small for the blower are the common findings, and only one of those three is solved by cleaning duct.
The previous tenants had pets. Does a cleaning reset that?
Partly, and we would rather set the expectation now. Cleaning removes dander and hair that settled in the duct and on the coil, which genuinely helps. It does not touch carpet, padding or drywall. If the smell persists after a proper cleaning, the source was never the duct system.
