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 typically runs $350 – $650 for a whole-home system, with most jobs completed in a single visit. What drives the actual price is the age of your ductwork, how much caliche dust and live oak pollen has built up, and whether we’re working with rigid metal ducts or the sagging flex runs common in pre-1990s San Antonio homes. We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and we dispatch crews from our San Antonio office to handle the specific conditions this city’s climate and housing stock throw at duct systems. Call us at (361) 326-5060 for a free estimate.
Why San Antonio Homes Are Different
San Antonio’s heavy caliche dust and live oak pollen coat duct systems differently than in other Texas cities, and the city’s pre-1990s neighborhoods often have flex duct runs that sag and collect this debris, making annual cleaning a necessity rather than a luxury. Much of the housing stock here consists of 1950s – 1980s single-story ranch homes and 1990s – 2000s tract homes, many still running original flexible ductwork that’s prone to sagging, kinking, and debris accumulation. In older neighborhoods like Alamo Heights and Monte Vista, original ductwork often shows signs of rodent intrusion and nesting, a problem exacerbated by the city’s warm climate.
The hot, humid summers with average highs in the 90s°F and mild winters mean HVAC systems run almost year-round, circulating dust, pollen, and mold spores through ducts more frequently than in cooler climates. This constant operation packs debris tighter against duct walls and accelerates buildup in low spots where flex duct has lost its pitch. When we open a system in Terrell Hills or King William, we’re often looking at layers of compacted caliche that standard vacuum methods won’t touch, which is why we bring rotary brush systems and negative-air machines on every San Antonio job.
Our Main San Antonio Services
San Antonio homeowners call us most often for these three services, each handled with The Garrison Standard of written pricing, background-checked uniformed technicians, and our 365-Day Done Right Promise.
Air Duct Cleaning in San Antonio
Our Air Duct Cleaning in San Antonio covers the full supply and return system, from the air handler to each vent. In this market, we regularly find flex duct runs that have sagged into the attic insulation, creating pockets where caliche dust and pollen compact into dense mats. We use rotary brush systems to agitate that debris loose, then extract it with negative-air machines so nothing settles back into your living space. Every job gets a written price before we start, and we photograph the duct interior before and after so you see what came out.
Dryer Vent Cleaning in San Antonio
Our Dryer Vent Cleaning in San Antonio removes lint buildup from the dryer transition duct through to the exterior termination. San Antonio’s warm, humid climate causes lint to clump and stick to vent walls more aggressively than in drier regions, and the longer vent runs common in 1970s – 1980s ranch homes increase fire risk. We clean the full run with professional augers and inspect the exterior hood for proper flap operation. The price is written before we touch anything.
Duct Sealing in San Antonio
Our Duct Sealing in San Antonio addresses the leaks and separations that cost homeowners money every month. In neighborhoods with original flex duct, we often find seams that have pulled apart at the plenum and registers, dumping conditioned air into attics that hit 140°F in July. We seal with mastic and mechanical fasteners, then pressure-test to verify the seal holds. Like every Hollis job, it’s priced in writing upfront and covered by our 365-Day Done Right Promise.
