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.
Air Duct Cleaning Company in Sonterra, TX
Air duct cleaning in Sonterra runs between $290 and $575 for most single-family homes, depending on system size and how long it’s been since the last cleaning. We’re Cardinal Air Duct Cleaning, part of the Relay Home Co. family founded in 2005, and we handle air ducts, HVAC cleaning, and dryer vents across Sonterra with a written price before any work begins. Sonterra homes sit in Texas heat and humidity that push HVAC systems hard, which means dust, dander, and construction debris accumulate faster than homeowners expect. Call (737) 727-2314 for a free estimate.
Why Sonterra Homes Are Different
Sonterra’s housing stock is a mix of newer builds and established homes, and both present real challenges for ductwork. Newer construction leaves behind drywall dust, paint overspray, and sometimes loose debris inside return and supply lines before the first owner ever moves in. Older Sonterra homes have had years of Texas pollen, cedar, and oak working through the system, often with original flex duct that’s beginning to degrade. The local climate compounds it: long cooling seasons mean your AC circulates air through those ducts for eight or nine months a year, and humidity invites the kind of microbial growth that settles on coil surfaces and inside plenums. We see homes where return ducts have pulled dust from every renovation, every pet season, and every stretch of construction activity nearby. Sonterra’s terrain also sits over a mix of soil types that shift with drought and rain cycles, and that movement can leave duct connections slightly separated, pulling attic air and insulation fragments into the system. It’s a cumulative problem, and it’s why a straightforward visual check of your register covers doesn’t tell you much about what’s actually coating the inside of your ducts.
Our Main Sonterra Services
Most Sonterra homeowners reach out to us first about one of two things: dryer vents that are taking longer to dry clothes, or air ducts that haven’t been touched since the house was built. Here’s how each service works locally.
Dryer Vent Cleaning in Sonterra
A clogged dryer vent in Sonterra is a fire hazard and a daily annoyance. Texas heat means dryers run often, and lint builds up fast in vents that route through attics or up through the roof, common in Sonterra’s single-story and two-story layouts. We run professional brush systems through the full vent run and pull the loosened lint out with HEPA-rated negative pressure, so it doesn’t get blown back into your laundry room. If your dryer has started taking two cycles to dry a load, or you can’t remember the last time the vent was serviced, it’s worth having it looked at. That’s detailed on the Dryer Vent Cleaning in Sonterra page.

Air Duct Cleaning in Sonterra
Air duct cleaning here means getting the years of accumulated dust, pet hair, and construction debris out of your supply and return lines. We use Rotobrush rotary brush systems to agitate debris off duct walls and Nikro HEPA vacuums for negative-pressure extraction, which means everything we loosen goes into the vacuum, not back into your living space. Sonterra’s cooling-heavy climate means ducts work constantly, and when they’re dirty, that dust recirculates through every room. You can read the full breakdown on the Air Duct Cleaning in Sonterra page.

HVAC Cleaning in Sonterra
HVAC cleaning goes past the ducts to the equipment itself. In Sonterra, where the AC runs hard through spring, summer, and early fall, evaporator coils collect a layer of dust and the blower wheel can cake with debris that cuts airflow and efficiency. We clean coils, blower assemblies, drain pans, and plenums, then check the condensate drain for the clogs that lead to water damage in humid months. This is heavier work than a duct-only cleaning, and it’s the service that makes the biggest difference when your system is running but not cooling like it used to. More on the HVAC Cleaning in Sonterra page.

No, duct and vent cleaning is routine maintenance, not a structural change, so Sonterra HOA approval isn’t required for the work itself. Access to your system just needs a clear path to the indoor unit and attic entry. Call us if you want to confirm anything specific.
We hand you a written price before work starts, and afterward you receive before-and-after photos of your own ducts, not stock images. That’s part of The Relay Standard every Sonterra booking includes, and it’s how you can see exactly what was cleaned. Call (737) 727-2314 for a free estimate.
