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 League City, TX
Air duct cleaning in League City is different from most Houston suburbs because this city sits directly between Clear Lake and Galveston Bay. That means two things for your ductwork: salt-laden humidity runs higher than inland, and much of the housing stock was built fast during the NASA boom with flex duct routed through attics that hit 140°F in summer. The combination creates duct interiors that hold moisture, grow mold, and shed fiberglass liner particles into living spaces. Kestrel Air Duct Cleaning operates under the Kingswell Guarantee: a written price before any work begins, a defined arrival window, a clean job site, and a written guarantee on the work, with a free return visit if it fails within the guarantee period. Call (469) 972-3151 for an honest assessment.
Why League City Homes Are Different
Most League City homes are 1980s to 2000s slab-on-grade tract builds, put up during the Clear Lake aerospace-worker expansion anchored by Johnson Space Center. The standard duct system in these houses is fiberglass flex duct snaked through attic spaces that bake in Gulf Coast heat. Flex duct has an inner plastic liner, and after 15 to 25 years of thermal cycling, that liner starts to degrade. Tiny cracks let humid attic air pull into the duct interior every time the AC cycles off. When that moist air meets the cool metal supply boot, condensation forms. We regularly open supply registers in League City and find visible mold bloom right at the boot connection, even in homes that never took on flood water.
Hurricane Harvey in 2017 and the repeated Clear Creek flood events of 2015 and 2016 left a deeper mark. In neighborhoods along the creek’s flood plain, including South Shore Harbor, Westover Park, and Tuscan Lakes, thousands of homes were remediated but kept their original duct systems. Flex duct inner liners are porous when saturated, and flood moisture that wicked into the liner never fully dried, even after drywall was replaced. Five, six, seven years later, we still find the signature: mold concentrated inside the supply boots and along the bottom seam of the flex runs. That is not a dust problem. It is an active indoor-air-quality issue that standard vacuuming will not resolve.
League City’s spot between Galveston Bay and Clear Lake also means AC systems rarely get a true seasonal break. Indoor humidity stays elevated year-round, and condensation inside duct runs forms on a cycle that inland suburbs like Sugar Land or Pearland simply do not experience to the same degree. Our techs use negative-air extraction, which means a Nikro unit pulls a continuous vacuum on the duct system while Rotobrush rotary agitation dislodges what is stuck to the walls, keeping loosened material out of the house. In League City’s climate, that containment step matters more than in drier towns.
Our Main League City Services
League City homeowners call Kestrel for two things: cleaning the ducts that move conditioned air, and clearing the dryer vent that carries lint out of the house. Each has its own page with local pricing detail.
Air Duct Cleaning in League City
We clean supply and return duct runs, supply boots, return plenums, and the blower compartment. In League City, the job almost always includes addressing mold bloom at the boot connection and degraded flex liner inside the attic runs. Rotobrush rotary brush systems dislodge debris at the duct wall while a Nikro negative-pressure unit pulls contaminants out, and Abatement Technologies HEPA filtration keeps loosened particles out of the living space during cleaning. The full detail is on the Air Duct Cleaning in League City page.
Dryer Vent Cleaning in League City
Salt-laden air near the bay means dryer exhaust carries heavier particulate, and League City dryer vents tend to pack lint faster than inland homes. We clear the full run from dryer to exterior termination, including lint trap bypass, where we remove the lint caught inside the dryer’s own housing before the wall. The detail on pricing and what to expect is on the Dryer Vent Cleaning in League City page.

Whatever the finding, the written price is in your hands before a single vent is touched. No doorstep revisions, no surprise line items.

What League City Customers Say
"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."
- 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."
