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 usually costs between $350 and $650 for a full system, and our technicians spend about 4 to 6 hours on a typical home here. Sonterra’s builder-era flex-duct systems run through attics that bake well past 140°F in summer, which breaks down duct liners and pulls fine debris into the airflow faster than most Texas homes. Add the Hill Country’s brutal winter Mountain Cedar season, and the ducts in Sonterra need a different kind of attention than what works in flatter, less pollen-saturated markets. Call (469) 972-3151 and we’ll give you a written price before any work starts.
Why Sonterra Homes Are Different
Sonterra sits on the northern fringe of San Antonio, right at the edge of the Hill Country, and that location means two forces work against your ducts year-round. First, the heat. Homes here are mostly 2000s-to-2020s builder construction with flex-duct runs routed through unconditioned attics. Those attic spaces regularly exceed 140°F between May and September, which accelerates liner degradation and causes insulation particles to shed into supply plenums way faster than in the climate-controlled crawl spaces you’d find elsewhere. The AC system runs seven to nine months a year, pushing that debris through the duct network constantly.
Then comes cedar. The December through February Mountain Cedar event is the defining air-quality crisis for this corridor. Pollen counts routinely exceed 20,000 grains per cubic meter, and that fine, sticky Ashe Juniper pollen loads return-air ducts with a residue that a standard 1-inch filter can’t stop. Our technicians repeatedly find homes in Sonterra where the homeowner replaced filters in late November, and by mid-January the return plenum is visibly coated. The system draws that contaminant-laden air past the filter media and straight into the ductwork for weeks before anyone notices. No Dallas or Houston technician encounters this cycle; Sonterra’s duct-cleaning demand follows the cedar calendar.
Our Main Sonterra Services
Most Sonterra homeowners call us about one of two jobs, and each has its own dedicated page with specific pricing and details.
Air Duct Cleaning in Sonterra
We clean the full air path: return registers, supply runs, plenums, and the main trunk lines. In Sonterra, that almost always means dealing with cedar pollen residue packed into the return side and insulation debris from degraded flex-duct liners in the supply side. We run negative-air extraction with professional-grade Nikro equipment so what we loosen gets pulled out of the living space, not blown through it. Our technicians are background-checked and uniformed, and the written price is in your hands before a single vent is opened. Full details: Air Duct Cleaning in Sonterra

Dryer Vent Cleaning in Sonterra
Dryer vents in Sonterra homes run long horizontal stretches through those same superheated attics, which bakes lint onto the duct walls until the airflow drops. We clean the full length from the dryer to the exterior terminator, check the exterior damper, and use a lint trap bypass so the job actually removes what’s packed inside the line. Lint buildup is the leading cause of dryer fires, and in Sonterra the lint gets hard and crusted from the heat, which makes a box-store brush useless. Full details: Dryer Vent Cleaning in Sonterra

Pricing for Air Duct Cleaning Company in Sonterra, TX
These are the ranges we quote most often for Sonterra homes. The exact figure depends on home size, number of returns, and how badly the system is loaded – but the price we give you in writing is the price you pay.
| Service | Typical range in Sonterra |
|---|---|
| Full air duct cleaning (entire home) | $350 - $650 |
| Main trunk-line cleaning only | $200 - $350 |
| Return plenum and return duct cleaning | $150 - $250 |
| Supply plenum and supply duct cleaning | $150 - $250 |
| Furnace blower fan cleaning | $75 - $125 |

| Dryer vent line cleaning | $85 - $150 |
| Dryer vent with roof or long-run access | $125 - $200 |
What pushes prices higher in Sonterra is almost always cedar loading and attic access. A home with multiple returns pulling pollen-heavy air during cedar season typically needs more time per return, and long attic runs through 140°F heat make the work slower and dirtier. We still quote one flat price per system before we begin, and we stand behind it in writing.

What Sonterra Customers Say
"Bought an older home and the previous owners had pets everywhere. After Kestrel did the ducts the stale smell was just gone. On time, quick, and they showed me the filter they pulled."
- Preston Ngata"Our dryer was taking two cycles to dry a load. They cleaned the vent and pulled out a frightening amount of lint. Dries in one cycle now and honestly I feel better about the fire risk."
- Marcus Lee"Set up an appointment for the whole house plus the dryer line. They called the morning of to confirm, showed up in the window, and showed me pictures of the gunk they pulled out. Worth it."
