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 Sandy Oaks, TX
Hollis Air Duct Cleaning serves Sandy Oaks with whole-home duct cleaning, dryer vent cleaning, and duct sealing backed by written prices and a 365-Day Done Right Promise. Sandy Oaks sits on the edge of the Eagle Ford Shale, where caliche dust storms and active oil and gas operations create a particulate load that most Texas homeowners never deal with. That fine, powdery dust migrates into return-air ducts, coats blower motors, and accelerates the need for professional cleaning compared to other south Texas markets. If you’re seeing dust settle on furniture within days of wiping it down, or your HVAC filter clogs faster than the package suggests, your ductwork is likely the culprit. Call us at (361) 326-5060 for a free estimate.
Why Sandy Oaks Homes Are Different
Sandy Oaks is a small, predominantly rural community just south of San Antonio, with housing stock that ranges from older single-family homes to manufactured housing and newer custom builds on large lots. Many of these homes have long duct runs in unconditioned attics, which means conditioned air travels through 120-degree spaces in July before it ever reaches your living room. That temperature differential creates condensation points where dust and microbial growth collect.
The region’s humid subtropical climate keeps HVAC systems running almost year-round. Long, hot summers and short, mild winters mean your blower motor rarely gets a rest, which accelerates dust buildup throughout the system. Add the local caliche dust and pollen from area brush, and the particulate load is substantial. After a dry, windy day, our technicians regularly find a visible layer of caliche dust inside supply registers on the south and west sides of homes, a clear signature of Sandy Oaks’ shale-country environment. This isn’t a one-time problem; it’s a recurring condition that requires ongoing attention.
Our Main Sandy Oaks Services
Most Sandy Oaks homeowners call us for one of three jobs. Each has its own dedicated page with full details on what’s included, how we price it, and what you should expect on the day of service.
Air Duct Cleaning in Sandy Oaks
We clean the full supply and return trunk lines, branch ducts, and registers using a Rotobrush rotary brush system or Nikro negative-air machine depending on your duct material and contamination level. In Sandy Oaks, we often find caliche dust packed into the return plenum and coating the evaporator coil, which reduces airflow and forces your compressor to work harder. We remove that buildup, clean each register face and boot, and run a final negative-air pull to capture loosened debris. Air Duct Cleaning in Sandy Oaks is priced by the system, not by the vent, with a written quote before we start.
Dryer Vent Cleaning in Sandy Oaks
Lint buildup in dryer vents is a leading cause of house fires, and in Sandy Oaks the combination of fine caliche dust and lint creates a particularly dense blockage. We run a rotary brush with reverse-blowing skipper ball through the full vent line to the exterior termination, then measure airflow before and after to confirm the restriction is gone. Homes with long vent runs through unconditioned attics, common here, are especially prone to moisture accumulation and clogs. Dryer Vent Cleaning in Sandy Oaks typically takes 60 to 90 minutes and includes a written report of what we found.
Duct Sealing in Sandy Oaks
Leaky ducts in Sandy Oaks attics waste conditioned air into spaces where it does no good. We apply duct sealing mastic to accessible joints and connections, then pressurize the system to verify seal integrity. Older homes with fiberglass duct board and manufactured housing with flex-duct runs are common here, and both benefit substantially from proper sealing. The payoff is lower utility bills and more even temperatures room to room. Duct Sealing in Sandy Oaks is quoted as a flat system price after we assess access and duct condition.
