Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterAir Duct Cleaning Company in Alamo Heights, TX
Air duct cleaning in Alamo Heights means working inside homes built long before central air conditioning was ever planned for them. Most houses here date from the 1920s through the 1950s, so nearly every HVAC system was retrofitted into attic spaces and wall cavities never designed to hold ductwork. That creates a very different job than what you’ll find in newer San Antonio suburbs, and it’s why we approach every Alamo Heights home with a careful eye for older materials, tight chases, and the dust those systems carry. Call (469) 972-3151 if you want a straight answer about your home.
Why Alamo Heights Homes Are Different
Walk through Alamo Heights and you’ll see brick bungalows, Tudor revivals, and Colonial-style homes on lots shaded by mature live oaks. What you won’t see is the ductwork, and that’s usually the problem. Many of these houses got central air in the 1960s through 1980s, when window units were finally replaced. The ducts were often run through shallow attic cavities that hit 150°F in a San Antonio summer and squeezed into wall chases with irregular geometry. Those systems collect debris differently than purpose-built ductwork, and they degrade differently too. Joints loosen, seams separate, and the heat stresses materials over decades of cycling.
Then there’s the air itself. San Antonio’s mountain cedar season peaks from December through February and produces some of the highest airborne pollen concentrations in North America. Alamo Heights’ dense live oak canopy adds a second heavy pollen pulse every spring. If your ducts are older and leakier, that pollen is moving through your home every time the system cycles. We’ll also point out that a lot of Alamo Heights attic duct systems still use duct board or early flex duct from the 1970s and 80s. That material gets brittle with age. We routinely find collapsed inner liners and disconnected joints that have been silently dumping conditioned air, and dust, into the attic for years. Cleaning an older Alamo Heights system isn’t a generic job. It’s an inspection of materials that have outlived their intended lifespan, combined with a real cleaning of everything attached to them.
Our Main Alamo Heights Services
Alamo Heights homeowners call us about two things: the ductwork carrying their conditioned air and the dryer vent that carries hot lint out of the house. Both need attention in this city’s older homes, and both have their own dedicated pages here.
Air Duct Cleaning in Alamo Heights
Air duct cleaning in Alamo Heights starts with looking at what kind of ductwork you actually have, because the house will tell us what to expect. Early flex duct and duct board from the 1970s and 80s needs a different touch than sheet metal. We use negative-air extraction, which means a vacuum unit pulls air through the ducts while rotating brushes dislodge debris stuck to the duct walls. In a Alamo Heights attic, we’re also looking for disconnected joints and collapsed liners while we work, because those are common in retrofitted systems and they defeat the point of cleaning if left unaddressed.

Dryer Vent Cleaning in Alamo Heights
Dryer vent cleaning in Alamo Heights matters because older homes often have longer, less direct vent runs. A vent that winds through a wall cavity or crawls across an attic collects lint at bends, and that’s exactly the setup many pre-1960 homes here have. We clean the full run from the dryer to the exterior termination, and we clear the lint trap bypass instead of just vacuuming behind the dryer. The goal is a vent that a dryer can actually push air through efficiently, which matters more in this city’s older construction than it does in a house built last decade.

Brands We Service in Alamo Heights
We clean systems regardless of brand, because the ductwork itself is what matters, not the cabinet it’s attached to. That said, we work regularly around Honeywell and Aprilaire filtration components found in Alamo Heights homes, and for homeowners who want to keep air clean between visits, Guardsman filtration products are available. We keep common replacement parts with us in the van so a simple filtration swap doesn’t mean a second trip. See our brands for the full picture.

Two things push pricing upward in Alamo Heights specifically. First, older retrofitted duct runs are often cramped and difficult to access, which slows the work down. Second, when we find collapsed liners or disconnected joints during a cleaning, sealing or replacing those sections adds cost. Whatever the price, it’s in your hands in writing before any work starts, and it doesn’t change at the door.

FAQs About Air Duct Cleaning Company in Alamo Heights
Most Alamo Heights appointments are scheduled within a few business days. Older homes with cramped attic access can make scheduling tighter during peak cedar season, but we’ll give you a defined arrival window when you book, and we stick to it. That window is part of the Kingswell Guarantee on every job.
Interior duct cleaning and dryer vent cleaning rarely require HOA review anywhere in Alamo Heights, because the work happens inside the home and at the existing exterior vent termination. If a job requires changing an exterior vent cover, we’ll flag it so you can confirm any aesthetic requirements with your association before we start.
Call us at (469) 972-3151 and describe what you’re seeing. We’ll ask a few questions about your home’s age, any recent renovations, and whether you’ve noticed dust or airflow issues. If an inspection is the right first step, we’ll say so plainly, and the written price covers whatever we agree to before work begins.

What Alamo Heights Customers Say
"Set up an appointment for the whole house plus the dryer line. They called the morning of to confirm, showed up in the window, and showed me pictures of the gunk they pulled out. Worth it."
- Terrence Boyd"My wife's allergies were awful every morning. Had the ducts done and it's made a real difference. Tech was on time and wore booties in the house without me asking."
- Rob Pendergast"Bought an older home and the previous owners had pets everywhere. After Kestrel did the ducts the stale smell was just gone. On time, quick, and they showed me the filter they pulled."
