What that means for ducts
Retrofit-era ductwork
About 48% of Highland Park's homes went up before 1980, which is before central air was designed into a house rather than added to it. Duct runs in that stock were threaded through attics and crawl spaces after the fact, often more than once, and the flex in them has had decades of Texas attic heat. Expect route surprises, expect joints that have worked loose, and expect a system nobody has opened.
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 Highland Park
The part that changes from street to street.
Highland Park is two housing stocks sharing the same block. About half the town still stands as it was built before 1980, 1920s and 30s masonry with plaster walls and no cavity ever intended to carry a duct, so the system arrived later and went in through closets, stair chases and attics with barely enough headroom to crawl. The rest of the street has been taken down and rebuilt since 2000, and those houses come with three or four zoned systems, a tight envelope and often a humidifier. Advice does not transfer between the two. In an original house we are looking for a run flattened where it crosses a chase, a duct-board plenum whose liner has gone soft, and returns that were never enlarged when the equipment grew. In a rebuild the duct is generally sound and the useful question is which of the systems is doing the work and which one is fighting the others.

03Plenum & Return-Box Cleaning — in this stock
Cleaning a system that was added, not designed in.
In pre-1980 stock the runs were threaded through the house after the fact — around plaster, through crawl spaces, across attics that were never meant to be conditioned. Two consequences for a cleaning: the route is rarely what the plans suggest, so the system gets mapped on camera before anything is agitated; and joints that have been flexing through forty Texas summers can let go under negative pressure. We would rather find that with a camera and quote the repair than discover it with a vacuum running.
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.

05Questions
Asked in Highland Park, answered straight.
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.
The house is original to 1929. Can you reach the ducts without opening plaster?
In most cases yes. We work through registers, boots and the plenums with a camera, which shows the interior condition of the runs and where a section has collapsed or separated. Occasionally a concealed stretch behind plaster cannot be reached any other way, and then we show you the footage and discuss an access panel before anything is cut.
We rebuilt in 2014 and the house still gets dusty. Are the ducts to blame?
Rarely at that age. Ten-year-old duct in a tightly built house is usually the cleanest part of the assembly, and dust in these rebuilds more often traces to filter bypass at the rack, a return chase drawing from an attic or garage, or simply the household. We would rather find the leak than sell you a cleaning that fixes nothing.
There are three thermostats and three filters. Does each one get inspected?
Each is a separate system and gets its own report and its own photographs. It is also common to find that the systems are in genuinely different condition, because one serves the main floor at full runtime and another serves guest rooms that sit idle. We would rather service one properly than quote all three as a package.
