What that means for ducts
Retrofit-era ductwork
About 30% of San Antonio'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 San Antonio
The part that changes from street to street.
San Antonio runs on electricity rather than gas. The large majority of homes heat with a heat pump or resistance strips, and with winters this short the system is effectively a cooling machine nine or ten months of the year. That concentrates wear and dust at the blower and the indoor coil rather than deep in the branch runs, and it is where we start. The second half of the picture is the inner loop. A substantial share of the housing inside 410 predates 1980, ducted through vented attics with thin insulation and served by a single return grille sized for a much smaller blower than anything sold today. Starved returns are the most common finding in those houses, and adding return area improves comfort and filtration more than a cleaning does. Outside the loop, pale limestone and caliche dust from ongoing construction gets pulled in wherever the return side leaks.

03New-Construction Duct Dust-Out — in this stock
Renovation dust in an old system.
A remodel in older stock pushes fines into ductwork that was already carrying decades of settled load, and the two mix. That matters for scope: this is rarely a register-level clean-up, because the debris travels back to plenums that have never been opened. It is also the one moment where a full system clean is unambiguously worth doing — the reservoir is at its worst and the house is already disrupted.
Shouldn't my builder have cleaned the ducts already?
Sometimes it's in the contract; often it's skipped or done superficially in the rush to closing. Ask your builder for documentation — an invoice and photos.
When is the ideal time to schedule a dust-out?
After the final sanding and paint work, before move-in — that's when the ducts have collected everything they're going to collect and your belongings aren't in the way. Already moved in? Still absolutely worth doing; the work is identical, we just add drop cloths and a little more care around furniture..

If they can't produce it, our camera answers the question in an hour, and the pre-clean photos give you standing to raise it before your warranty window closes.

Inside Loop 410 our house dates to 1962. What usually turns up?
In that stock the duct runs through a vented attic with thin insulation, served by returns sized for a much smaller blower. We commonly find a single undersized return grille starving the whole system. Adding return area improves comfort and filtration noticeably more than a cleaning of the branches would.
Heating barely runs here. Is my system really just an air conditioner?
Effectively yes, and it changes priorities. With mostly electric equipment and very short San Antonio winters, the blower and indoor coil see nine or ten months of runtime a year. That is where dust and moisture concentrate, and that is what we open first rather than the branch runs.
Fine pale dust settles on everything in our house. Is it coming from the ducts?
More often it is getting in through them. Limestone and caliche dust from construction and unpaved edges is drawn in wherever the return side leaks, then distributed through the house. Finding and sealing that leak is the durable fix. Cleaning without it just delays the same complaint by a season.
