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 Seguin, TX
Air duct cleaning in Seguin runs most homes between $350 and $650 for a full-system cleaning, depending on home size, duct condition, and whether you add a dryer vent cleaning. What makes Seguin different is what’s in the air: pecan pollen, river-valley humidity, and decades of accumulated debris in older retrofitted ductwork. We’re Kestrel Air Duct Cleaning, part of the Kingswell family of companies, and we give Seguin homeowners a written price before any work starts. Call (469) 972-3151 for a free estimate.
Why Seguin Homes Are Different
Seguin sits at the eastern edge of the Hill Country where the Guadalupe River valley traps humidity. Indoor relative humidity runs higher here than in drier cities just twenty miles west, and with central AC cycling nearly nine months a year, the inside of a duct system stays warm and damp far longer than it should. That’s the environment where dust mites colonize and mold takes hold.
Add the canopy. Seguin is the Pecan Capital of the World, and the dense pecan trees lining neighborhoods like the historic core near Court Street produce heavy pollen loads every spring and organic leaf debris every fall. That material gets pulled into HVAC return vents, settles inside ductwork, and mixes with condensation on duct surfaces into a sticky tan-brown film. Long-time Seguin homeowners know exactly what that film looks like when a vent cover comes off.
Older homes in the historic districts frequently have ductwork that was retrofitted decades ago, with aging flex duct and loose connections that collect debris and lose integrity under heavy seasonal HVAC use. Newer slab-on-grade subdivisions pushing east along US-90 and TX-46 have their own issue: construction dust from the build itself, baked into the system before the first owner ever moved in.
Our Main Seguin Services
Seguin homeowners call us most often for two things: cleaning the ductwork that moves heated and cooled air through the house, and clearing the dryer vent that expels lint and moisture to the outside. Each has its own dedicated Seguin page below.
Air Duct Cleaning in Seguin
Full-system Air Duct Cleaning in Seguin removes the pecan pollen film, construction dust, pet dander, and the fine tan-brown grit that accumulates throughout the supply and return lines. We use negative-air extraction, meaning a HEPA-filtered vacuum pulls debris out under suction rather than pushing it into the living space, paired with rotary brush agitation that scrubs the duct walls themselves. In Seguin’s older homes near Court Street, we regularly find retrofitted flex duct that has never been properly cleaned since installation.
Dryer Vent Cleaning in Seguin
Lint accumulation in dryer vents is a fire hazard in any city, but Seguin’s humid air makes lint heavier and stickier, which means it builds up faster on vent walls and at the external vent cap. Our Dryer Vent Cleaning in Seguin clears the full vent run from the dryer connection to the outside termination, removing the compacted lint that slows drying times and raises dryer temperatures. You get a written price before we start, and the work is covered by the 365-Day Done Right Promise.

What pushes the price toward the top of the range in Seguin is usually the age of the ductwork. Retrofitted flex duct in homes built before central AC was standard tends to have loose connections, accumulated debris pockets, and sections that need more careful attention than a newer slab-on-grade system. Whatever the number, you get it in writing before a single vent is touched. That’s the Kingswell Guarantee, and it applies to every job we do in Seguin.

What Seguin Customers Say
"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."
- Terrence Boyd"My wife's allergies were awful every morning. Had the ducts done and it's made a real difference. Tech was on time and wore booties in the house without me asking."
- Rob Pendergast"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."
