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.
Fast, Reliable Air Duct Cleaning Across Round Rock
Air duct cleaning in Round Rock typically runs $350 – $650 for a full residential system, with most jobs completed in a single visit. We dispatch crews from our Austin scheduling office and cover all Round Rock neighborhoods from downtown’s older ranches to the master-planned subdivisions along IH-35 and the tollways. Call (361) 326-5060 for a written estimate before any work starts.
We’ve been working in Round Rock long enough to know the local housing stock inside and out. The homes in Forest Creek, Teravista, and Stone Canyon aren’t like Austin’s older pier-and-beam inventory. They’re slab-on-grade builds from the 1980s through the 2010s with flex-duct systems that were often undersized from day one. That matters because a standard duct cleaning without airflow testing can miss the real problem: collapsed runs, sagging flex behind drywall, and return plenums pulled apart by blackland prairie soil movement. Our Air Duct Cleaning team treats the whole system, not just what you can see at the vent.

We know Round Rock’s specific problems: the construction debris left in new-build ducts, the 130°F attics that collapse undersized flex runs, the soil-shifted plenums that leak attic dust into your returns. That local knowledge means we diagnose correctly the first time, not after three callbacks.
HVAC Duct Cleaning in Round Rock
HVAC Duct Cleaning in Round Rock addresses the full forced-air system: supply ducts, return ducts, the air handler cabinet, and the plenum connections. In Round Rock’s climate, this matters more than in milder markets. Our cooling season runs May through September, and AC systems operate almost continuously, pulling dust, pollen, and insulation particles through the ductwork at high velocity. Winter’s occasional hard freezes can cause condensation and mold if seals are compromised. A full HVAC duct cleaning removes built-up debris and lets us inspect for the airflow restrictions that cost you money every month on your electric bill.
For a typical Round Rock home, HVAC duct cleaning runs $400 – $700 depending on system size and accessibility. Two-story homes with attic air handlers fall at the higher end. We use Rotobrush rotary brush systems for mechanical agitation and Nikro negative-air machines to maintain controlled suction throughout the job.
Supply Duct Cleaning
Supply ducts push conditioned air into your rooms. In Round Rock’s newer subdivisions, we regularly find drywall dust and construction debris still trapped in these lines from the original build, especially in homes under five years old. Our rotary brush system breaks that debris loose while negative pressure pulls it out of the house entirely, not just deeper into the system.
Return Duct Cleaning and Airflow Testing
Return ducts pull air back to the air handler for reconditioning. This is where Round Rock’s soil-shifted plenums and collapsed flex runs show up. We run video inspection and static pressure testing to verify the return path is intact before we call the job complete. Cleaning a collapsed duct is pointless; restoring airflow is the actual fix.
Vent Cleaning in Round Rock
Vent Cleaning in Round Rock focuses on the register grilles, boot connections, and the first few feet of duct run behind each vent. This is the visible part of the system, and it’s where homeowners notice problems first: dust blowing out when the AC kicks on, musty smells, or registers that won’t stay clean. In Round Rock’s heavy pollen seasons, vent surfaces load up fast with fine particulates that standard household dusting won’t remove.
Vent cleaning as a standalone service runs $150 – $300 for a typical Round Rock home, though we usually recommend it as part of a full system cleaning for homes with systemic debris or airflow issues. The standalone service makes sense for maintenance between full cleanings or when only certain rooms show symptoms.
Register and Boot Detailing
We remove each register grille, clean the boot connection where the duct meets the wall or floor, and treat for mold or mildew if the boot shows moisture staining. In Round Rock’s humid cooling season, boots in bathrooms and kitchens are prone to this.
Video Verification
After vent cleaning, we show you the camera footage. You’ll see the before condition and the after. No guesswork, no trust-me language. The footage is yours to keep.

Common Air Duct Cleaning Problems We See in Round Rock Homes
- Construction debris in new builds. Homes in Teravista, Forest Creek, and Stone Canyon built in the last decade often have drywall dust and wood particulate still coating the supply ducts from original construction. The builder’s rough clean doesn’t reach the ductwork. We find it with camera inspection and remove it with source-removal methods.
- Collapsed flex runs in two-story attics. Round Rock’s 130°F attic temperatures soften the cheap flex duct builders install. Negative pressure from restricted returns can collapse a run entirely. The symptom is a hot upstairs room; the fix is resizing or replacement, not just cleaning.
- Soil-shifted return plenums. Blackland prairie soil shrinks in drought and swells in wet seasons. That movement pulls slab-on-grade return plenums apart at the seams, letting attic dust and insulation get sucked into the system. A surface cleaning won’t seal the leak.
- Mold from condensation in humid cooling seasons. Round Rock’s long AC season means cold ducts meeting humid attic air for months. Compromised seals create condensation points that support mold growth. We flag these during inspection and recommend sealing or insulation fixes.

FAQs About Air Duct Cleaning in Round Rock
Construction debris from the original build often remains in the ductwork for years after handover. Drywall dust, wood particulate, and insulation scraps get trapped in supply and return lines during construction, and the builder’s rough clean never reaches them. In Teravista, we inspected a 2016 two-story where the upstairs air handler sat in a 130°F attic and the return flex duct had collapsed from negative pressure. Our tech ran camera inspection and found drywall dust and construction debris still coating the supply and return ducts from the original build. After source removal with negative pressure and HEPA filtration, we resized the sagging run and restored proper airflow – the homeowner finally got even cooling upstairs. If your home is under ten years old and you’ve never had the ducts cleaned, camera inspection will likely show debris the builder left behind. Call (361) 326-5060 for a free estimate.
Round Rock’s housing stock is newer and built on slab-on-grade foundations with blackland prairie soil that shifts dramatically with wet-dry cycles. That soil movement pulls return plenums apart at the seams, a problem you rarely see in Austin’s older pier-and-beam stock. Combined with undersized builder-grade flex duct in subdivisions like Forest Creek and Teravista, Round Rock homes often need airflow restoration, not just debris removal. Austin’s older hard-duct systems present different challenges. The climate is similar, but the construction methods and failure modes are distinct. Call (361) 326-5060 and we’ll ask the right questions for your home’s age and type.
Yes. Our Nikro negative-air machines maintain controlled suction throughout the job, preventing debris from escaping into your living space during cleaning. HEPA filtration on the exhaust captures particles down to 0.3 microns. We follow source-removal methods: mechanical agitation with Rotobrush rotary brush systems to break debris loose, then immediate extraction under negative pressure. This is the standard for professional duct cleaning and the only method we use. Call (361) 326-5060 to schedule.
Not if the problem is collapsed or undersized flex duct, which we see constantly in Round Rock two-story homes. Standard cleaning removes debris but doesn’t restore airflow through a collapsed run. We test static pressure and run camera inspection to find the restriction. If the duct is collapsed, sagging, or undersized for the load, we quote resizing or replacement in writing before proceeding. The 2016 Teravista job we mentioned started as a cleaning call and ended with airflow restoration – the homeowner’s upstairs finally cooled evenly. Call (361) 326-5060 for diagnosis.
Every three to five years for typical maintenance, sooner if you’ve had construction, water damage, or visible mold. New-build Round Rock homes should get an initial cleaning within the first two years to remove construction debris. Homes with heavy pollen exposure, multiple pets, or residents with allergies may need cleaning every two to three years. The long, humid cooling season here means ducts work harder and longer than in milder climates. Call (361) 326-5060 for a free inspection and we’ll recommend a schedule based on your specific home and conditions.
