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 San Antonio, TX
Air duct cleaning in San Antonio runs $450 – $950 for a typical single-family home, and the job usually takes a half day. What makes San Antonio different is the combination of limestone dust, cedar pollen, and long cooling seasons that push more debris through your system than most cities see in a year. Cardinal Air Duct Cleaning brings professional-grade equipment, a written price before any work starts, and a 365-day promise to every job. Call (737) 727-2314 for a free estimate.
Why San Antonio Homes Are Different
San Antonio sits at the edge of the Texas Hill Country, which means two things for your ducts: limestone and cedar. The thin, chalky limestone soil kicks up fine dust that gets drawn into return vents, especially in neighborhoods like Stone Oak and Alamo Heights where lots sit on shallow bedrock. And from December through February, mountain cedar pollen from the Hill Country settles into homes even with windows closed, recirculating through the HVAC system for months afterward.
Housing stock matters too. A large share of San Antonio homes were built between 1970 and 2005, and many original duct runs are flex duct that sags, separates, or simply was never sealed well in the first place. Homes near Leon Valley and Helotes often have longer trunk lines to reach add-on rooms, which means more surface area for debris to collect. And because air conditioning runs from April through October, the system rarely gets a long rest, which lets moisture and dust bond inside the ducts in a way drier climates don’t see.
We also work around San Antonio’s HOA communities, where visible vent caps and roof penetrations sometimes need a quick heads-up to the property manager. It’s rarely a barrier, just a scheduling detail we handle up front.
Our Main San Antonio Services
Every Cardinal job in San Antonio starts the same way: a written price before anything gets touched, background-checked technicians in uniform, and the equipment listed on the work order. The two most-requested services are below, each with its own dedicated San Antonio page.
Dryer Vent Cleaning in San Antonio
Dryer vents in San Antonio clog faster than homeowners expect because the lint mixes with the same fine limestone dust that settles everywhere else. Long vertical vent runs, common in two-story homes around Alamo Ranch and Cibolo, are especially prone to blockages. Our crews use rotary brushes and HEPA vacuum extraction to clear the full run, from dryer to exterior cap. If the vent line is crushed or separated behind a wall, we’ll tell you and quote the repair separately. Full details and pricing on the Dryer Vent Cleaning in San Antonio page.
Air Duct Cleaning in San Antonio
Duct cleaning here is a full-system job: return and supply ducts, boots, registers, the blower compartment, and the plenum. We run a Rotobrush rotary brush through the ductwork while a Nikro HEPA vacuum pulls negative pressure, so loosened debris goes straight into the containment unit, not back into your living room. San Antonio’s long cooling season means the system has been moving air almost nonstop, and that air is what you breathe. See the full process and pricing on the Air Duct Cleaning in San Antonio page.
HVAC Cleaning in San Antonio
HVAC cleaning goes beyond the ducts: we clean the evaporator coil, blower motor, drain pan, and the surrounding cabinet. In San Antonio, where the AC runs for eight straight months, coil buildup cuts efficiency and drives up electric bills. Our techs document every step with before-and-after photos, so you see exactly what was removed. We also check the condensate drain line, a common source of water damage in Texas homes.

Almost never. Duct and vent cleaning is interior work with no exterior changes, so HOA rules in Stone Oak, Alamo Ranch, and similar communities don’t apply. If a roof access is needed on a larger commercial-style system, we’ll flag it before the visit.
We stop, show you photos, explain what we found, and hand you a written price for the additional work. You approve it or you don’t. Nothing extra gets done without your okay, and the original price stays as quoted.
