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 Round Rock, TX
Round Rock homeowners typically pay $350 – $650 for whole-house air duct cleaning, with most jobs scheduled within a week and completed in a single morning. The real challenge here isn’t the dust, it’s the ductwork itself: tens of thousands of homes in master-planned subdivisions built from the 1980s through the 2010s have builder-grade flex duct that’s undersized for the square footage and prone to collapse behind drywall. We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and we dispatch crews to Round Rock from our Austin scheduling office. Call us at (361) 326-5060 for a free estimate with a written price before any work starts.
Why Round Rock Homes Are Different
Round Rock’s explosive growth created a housing stock unlike neighboring Austin. Forest Creek, Teravista, and Stone Canyon are filled with two-story, slab-on-grade homes built between 1985 and 2020, almost all with original flex-duct systems and central returns that were never designed for the square footage they serve. We’ve found collapsed runs in attics across Round Rock where the negative pressure from an undersized return pulled the ductwork flat against itself.
The blackland prairie soil here shifts dramatically with wet-dry cycles, and that movement separates return plenums at the seams. Combine that with a cooling season that runs May through September, pulling dust, pollen, and insulation particles through the system at high velocity, and you get ductwork that needs more than a surface cleaning. In many two-story homes, the upstairs air handler sits in a 130°F attic, and the flex duct loses so much cooling that the system works against itself. Winter’s occasional hard freezes can also cause condensation and mold where seals have failed. These aren’t generic problems, they’re Round Rock problems.
Our Main Round Rock Services
Most Round Rock calls fall into three categories: restoring airflow to rooms that never cool evenly, clearing dryer vents in homes where the run exceeds 25 feet through the attic, and sealing ductwork that’s pulling attic air into the living space.
Air Duct Cleaning in Round Rock
We clean Round Rock ductwork with a rotary brush system from Rotobrush and negative-air machines from Nikro, the same tools commercial crews use. In Round Rock’s two-story homes, we often find the upstairs return collapsed or sagging where the flex duct couldn’t handle the static pressure. We photograph the condition before we start and again when we’re done, so you see what was actually in your system. Every job gets a written price upfront and is covered by our 365-Day Done Right Promise. Air Duct Cleaning in Round Rock
Dryer Vent Cleaning in Round Rock
Round Rock’s larger homes frequently have dryer vents that run 20 to 35 feet through the attic to an exterior wall, and lint accumulates in the low spots where the vent sags between trusses. We clean the full run with rotary brushes and high-velocity air tools, then check the termination for proper backdraft damper function. A blocked dryer vent in a Round Rock home is a fire hazard, not an inconvenience. Dryer Vent Cleaning in Round Rock
Duct Sealing in Round Rock
We seal Round Rock ductwork with mastic and metal-backed tape at every joint, collar, and plenum seam. In homes where the blackland prairie soil has shifted the return plenum apart, sealing restores the system’s designed airflow without replacing components that are otherwise sound. We test with a smoke pencil before and after to show you the difference. Duct Sealing in Round Rock
