What that means for ducts
Retrofit-era ductwork
About 35% of University 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 University Park
The part that changes from street to street.
A third of University Park is still the pre-1980 house it always was, and close to half has been rebuilt since 2000, so the system on any given lot is either ninety years of accumulated additions or something installed within the last decade. Then there is the third case: roughly a quarter of the housing here is not a detached house at all, and along the SMU corridor that means duplexes and garage apartments running a closet air handler, one hallway return grille and a filter changed whenever a tenant thinks of it. Three situations, three different conversations. In the surviving older houses the runs were threaded through knee walls and shallow attics above 1930s framing, and the joints have had decades to work loose. In the rebuilds the duct is young and the complaints trace to pressure and room-to-room balance. In the rentals, filter fit is most of the story and the rest belongs to the owner.

03Duct Sanitizing & Antimicrobial Treatment — in this stock
Treatment in stock with a moisture history.
Older houses are where microbial indications actually turn up, usually downstream of a moisture event nobody logged. Two rules apply and neither is negotiable: the source of the moisture is addressed first or the growth returns regardless, and porous material such as duct-board liner cannot be effectively cleaned — that is replacement work, not treatment. We will tell you which of the two you are looking at before anything is applied.
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 University Park, 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 rent a duplex near campus. Is a duct cleaning worth asking the owner for?
Usually not as your first ask. Behind the closet door of a unit like yours there is an air handler and a short length of duct, and that is all of it, so there is little to clean. Ask instead for the correct filter size and a change interval in writing, and report a return grille that whistles or a register that sweats. Those two complaints get real repairs approved; a general cleaning request rarely does.
Our 1936 house has ducts running through the knee walls upstairs. Is that bad?
It is common here and it is worth inspecting. A knee-wall pocket is unconditioned, so anything that leaks there is conditioned air paid for and lost, and any joint that opened is pulling that pocket's dust into the supply. The camera finds it quickly. What we usually recommend afterward is sealing and support work rather than cleaning.
The house was rebuilt in 2016 and the study is always stuffy. Are the ducts dirty?
Almost certainly not at that age. A closed door on a room with supply air and no return path pressurizes the room and stops the supply from entering properly. The fix is a transfer grille, an undercut door, or a dedicated return, and it costs a fraction of a cleaning. We check that before recommending anything else.
