Air duct work in San Antonio, TX
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.
01Where to start in San Antonio
Not every city needs the same thing first.
Older stock means retrofitted runs, joints that have worked loose, and flex that has spent decades in an attic. Look before you clean — a repair found first is cheaper than a cleaning done twice.

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.
On the ground in San Antonio
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.

05Questions
Asked in San Antonio.
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.
