Air duct work in Alamo Heights, TX
Most of what stands inside the Alamo Heights city limits predates the era when central air was designed into a house rather than added to it. On these 78209 streets, Spanish Colonial, Tudor revival and 1920s bungalow stock, the ductwork was threaded in later: through attics that were never meant to be conditioned, through pier-and-beam crawl spaces, around plaster walls that left no room for a chase.
01Where to start in Alamo Heights
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 67% of Alamo Heights'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 Alamo Heights
Most of what stands inside the Alamo Heights city limits predates the era when central air was designed into a house rather than added to it. On these 78209 streets, Spanish Colonial, Tudor revival and 1920s bungalow stock, the ductwork was threaded in later: through attics that were never meant to be conditioned, through pier-and-beam crawl spaces, around plaster walls that left no room for a chase. What you have is a retrofit, sometimes the second or third one, and no two houses on the same block took the same path. So we map the system before we clean it. Heating here is split roughly down the middle between gas furnaces and electric equipment, which means neighbors can have genuinely different dust and humidity behavior. And the live oak canopy that makes these streets what they are loads returns hard from late December through March. Sometimes the honest answer is better filtration, not a cleaning.

05Questions
Asked in Alamo Heights.
Our Alamo Heights house sits on pier-and-beam. Do ducts under the floor need different attention than attic runs?
Yes. Crawl-space trunks live in unconditioned, humid air, and older under-floor insulation absorbs moisture instead of shedding it. We look for sagging supports, rodent entry at the perimeter and torn liner before quoting anything. In a lot of these 78209 houses the finding turns out to be a repair rather than a cleaning.
Will duct cleaning help with the live oak pollen that coats everything here each spring?
Only partly, and we would rather you knew that up front. Oak pollen mostly enters through doors, windows and envelope leaks, then gets recirculated. Cleaning removes what has already settled inside the system; it does not stop next week's load. A properly sized, well-sealed return filter does considerably more for you.
The house dates to the 1930s and the ducts have never been cleaned. Is that a problem by itself?
Age alone is not a reason. EPA has never shown that routine cleaning prevents illness. What we actually find in Alamo Heights retrofits is more often mechanical: a run disconnected above a plaster ceiling, a crushed elbow, a boot that lost its seal decades ago. That is worth fixing on its own merits.
