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, FL
Air duct cleaning in San Antonio means contending with fine white caliche dust that settles into attic ductwork through every crack and seam in the building envelope. Homes here run their AC systems nine to ten months a year, pulling that dust across evaporator coils and into supply runs. Kestrel Air Duct Cleaning handles the whole system, from return plenum to supply registers, with a written price in your hands before any work begins. Call (469) 972-3151 for a free estimate.
Why San Antonio Homes Are Different
San Antonio sits atop a caliche-rich limestone substrate, and the city’s steady construction expansion keeps fine calcium carbonate dust suspended in the air for most of the year. That abrasive particulate works its way into homes and loads ductwork faster than in neighboring Austin or Houston. Because AC systems run almost continuously to combat 95 to 100 degree summers, ducts here accumulate debris at a pace that makes waiting multiple years between cleanings a genuine indoor air quality risk rather than a contractor upsell.
Most San Antonio homes are slab-on-grade with all ductwork in attics that routinely hit 140 to 160 degrees in summer. That kind of heat accelerates flex-duct liner degradation and causes duct tape mastics to fail prematurely. In 1970s to 1990s tract homes across Leon Valley, Converse, and Universal City, expansive Vertisol clay soils shift foundations seasonally, which can crack or partially disconnect older rigid duct sections without homeowners ever noticing. Add to that San Antonio’s spring and September-October humidity, which creates condensation inside attic supply ducts where cold air meets improperly sealed joints, and you have conditions where mold colonization in ductwork is a documented local problem. The December through February mountain cedar season, known locally as cedar fever, blankets the city with fine pollen off the Hill Country that infiltrates duct systems and compounds allergy loads for months.
Our Main San Antonio Services
San Antonio homeowners call Kestrel for two jobs more than anything else: full air duct cleaning and dryer vent cleaning. Each has its own dedicated San Antonio page with local pricing and details.
Air Duct Cleaning in San Antonio
Whole-system air duct cleaning in San Antonio targets the caliche dust, cedar pollen, and construction debris that settle in supply and return runs. We use negative-air extraction, which means a powerful vacuum pulls contaminants out of the ducts while brush agitation loosens debris stuck to the duct walls. In attic-ducted slab homes around the city, we also inspect accessible connections for separation caused by shifting clay soils. See Air Duct Cleaning in San Antonio for pricing and a step-by-step explanation of what the job involves.
Dryer Vent Cleaning in San Antonio
Dryer vent cleaning removes the layered lint that builds up over years of laundry loads, often compounded in San Antonio by fine dust drawn into the laundry room from outside. Our technicians use a lint trap bypass, which means we clean the full vent run behind the dryer, not just the removable screen you already clear by hand. For homes with second-floor laundry rooms and long vent runs through hot attics, the risk of restricted airflow is higher. See Dryer Vent Cleaning in San Antonio for local pricing and warning signs to watch for.

Prices in San Antonio push toward the upper end of these ranges when a home has a second system zoned for separate floors, or when attic access is cramped and duct runs require extended extraction time. Whatever the number ends up being, you’ll have it in writing before a single vent is touched.
Neighborhoods We Serve in San Antonio
Kestrel crews work throughout San Antonio and surrounding communities, including the neighborhoods surrounding Joint Base San Antonio where military PCS turnover means homes change occupants every two to three years with little to no cleaning history. Those ducts are often packed with layered caliche dust, pet dander from multiple prior tenants, and debris from spec-home construction around the base perimeter.

What San Antonio Customers Say
"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."
- Preston Ngata"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."
