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 is a job shaped by limestone dust, attic heat, and constant AC runtime. Most homes here run between $450 and $900 for a full-system cleaning, with smaller homes and condos landing closer to $300 and larger two-story homes with multiple returns reaching $1,200 or more. Kestrel Air Duct Cleaning gives you a written price before any work begins, and every job carries the 365-Day Done Right Promise in writing. When you call (469) 972-3151, you’ll speak with a live person who can schedule your San Antonio visit at a time that works for you.
Why San Antonio Homes Are Different
San Antonio sits on caliche-rich limestone, and the construction expansion pushing outward from Loop 1604 constantly stirs fine white calcium carbonate dust into the air. That dust finds its way through the building envelope and settles inside ductwork, mixing with the abrasive particulate that accumulates faster here than in neighboring Austin or Houston. Add in AC systems that run nine to ten months a year to keep 95 to 100 degree summers at bay, and San Antonio ducts build up debris at a pace that makes putting off cleaning a real indoor air quality problem, not a contractor scare tactic.
The housing stock makes things harder on duct systems. San Antonio’s dominant construction style is slab-on-grade with all ductwork running through attics that hit 140 to 160 degrees in July and August. That heat accelerates flex-duct liner degradation and causes older duct tape mastics to fail. Large portions of the 1970s through 1990s tract homes in communities like Leon Valley, Converse, and Universal City sit on expansive Vertisol clay, which shifts seasonally with moisture. When the soil moves, rigid duct sections can crack or partially disconnect, and homeowners never notice until airflow drops or a room stops cooling.
Then there’s cedar fever. Every December through February, mountain cedar pollen blows in off the Hill Country and settles across the city. That fine pollen infiltrates duct systems and hangs around for months, compounding allergy loads well after the peak season. Spring and early fall humidity intrusions create condensation inside attic supply ducts where cold air meets poorly sealed joints, which means mold colonization in ductwork is a documented local concern, not a hypothetical one.
Our Main San Antonio Services
San Antonio homeowners call Kestrel for two things more than anything else: getting years of caliche dust and construction debris out of their ducts, and clearing the dryer vents that lint has quietly packed tight. Each service has its own dedicated San Antonio page with pricing, process, and what to expect.
Air Duct Cleaning in San Antonio
San Antonio ductwork collects fine limestone dust, cedar pollen, and pet dander at a rate that surprises homeowners who’ve lived in other Texas cities. Our Air Duct Cleaning in San Antonio page covers the full process: negative-air extraction from a Nikro unit pulling loosened debris out of the duct system while a Rotobrush rotary brush scrubs the duct walls, and Abatement Technologies HEPA filtration keeping everything we dislodge out of your living space. You’ll find what a San Antonio job typically costs, how long it takes, and why we clean every register, return, and the main trunk line instead of spot-treating a few vents.
Dryer Vent Cleaning in San Antonio
Dryer vents in San Antonio clog faster than most people expect because lint combines with the same fine dust that loads the ductwork. Homes with second-floor laundry rooms and long vent runs through hot attics are especially prone to narrowed airflow. Our Dryer Vent Cleaning in San Antonio page explains the lint trap bypass method we use, how we clear runs from both the dryer connection and the exterior termination point, and why a clogged vent is the leading cause of dryer fires in single-family homes. If your clothes are taking two cycles to dry, that page will tell you what’s going on.

What pushes a San Antonio job toward the top of that range is usually attic access. A two-story home with all supply runs through a 150 degree attic and returns cut into upstairs ceilings takes longer to clean properly than a single-story ranch with accessible ductwork. The price we quote in writing before we start is the price you pay, no matter how long the job actually takes.

FAQs About Air Duct Cleaning Company in San Antonio
Most San Antonio visits can be scheduled within a few business days. We set a defined arrival window when you book, and the same tech who confirms the appointment is the one who shows up. Call (469) 972-3151 and we’ll find a slot that works for you, not the other way around.
No. Duct and dryer vent cleaning happens inside your home and at your existing exterior vent termination, so there’s no exterior modification that would trigger HOA review. If you’re in a gated community near Stone Oak or Alamo Ranch, let us know the gate code when you book and the tech will arrive ready.
Yes. Older homes with rigid metal ducts clean well, though sections may have separated at joints over the decades due to San Antonio’s shifting clay soils. During the job we’ll tell you if we find any disconnected runs. Call (469) 972-3151 for a specific quote on your home.

What San Antonio Customers Say
"Our dryer was taking two cycles to dry a load. They cleaned the vent and pulled out a frightening amount of lint. Dries in one cycle now and honestly I feel better about the fire risk."
- Marcus Lee"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."
