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 Katy
Most Katy homeowners pay between $380 and $650 for a complete residential air duct cleaning, with the exact figure depending on system size and whether video inspection reveals construction debris or separated flex duct that needs repair. Our crews are scheduled from the Houston office and cover Katy daily, including Cinco Ranch, Grand Lakes, Seven Meadows, and the older subdivisions off Mason Road and Fry Road. Call (469) 972-3151 and you’ll reach a live person who can book your arrival window and give you a written price before any work begins.
Katy isn’t a generic suburb. The master-planned communities built from 1993 through the 2010s, the Gulf Coast humidity that rarely dips below 70%, and the attic temperatures that cook flexible ductwork at 140-150°F for half the year create a specific set of problems we’ve learned to read block by block. We don’t guess. We inspect first, quote in writing, and clean with equipment built for the debris and mold conditions this climate produces.
Why Kestrel Air Duct Cleaning Is Katy’s Preferred Air Duct Cleaning Company
We’ve been in enough Katy attics to know the difference between a 1998 build off Franz Road and a 2012 build in Seven Meadows. The former usually has original flex duct that’s sagging at the hangers; the latter often has construction debris the builder’s crew never removed. That local pattern recognition matters because it tells our technicians where to look first, what camera to send down which run, and whether the homeowner needs cleaning, repair, or both.
Dale Whitmore built Kestrel under the Kingswell Guarantee in 2004, and every Katy job still carries the same four written promises: the price is fixed before work starts, the crew arrives in the window given, the job site is left cleaner than found, and the 365-Day Done Right Promise goes on paper before we leave. If something fails within that year, we return at no charge. Not as a favor. As a written obligation.
Our technicians are background-checked, uniformed, and trained on Rotobrush rotary agitation systems, Nikro negative-pressure extractors, and Abatement Technologies HEPA filtration. These aren’t shop vacs with longer hoses. The Rotobrush scrubs debris off the duct wall; the Nikro pulls it out under controlled suction; the HEPA unit keeps what we loosen from settling back into your living space. We also carry Honeywell and Aprilaire filtration products for homeowners who want to maintain clean air between service visits.
Calls are answered by a live person, 24 hours a day. No automated queue, no callback tag. When you’re trying to figure out whether that musty smell after a Katy summer storm is your ducts or your imagination, you talk to someone who can schedule an inspection, not a robot.
Vent Cleaning in Katy
Vent Cleaning in Katy starts at the register most homeowners see, but the real work happens 20 feet back in the attic flex runs where construction debris, pollen, and mold spores collect where you can’t reach. In Katy’s 2,500-4,500 square foot tract homes, a single system may have 15-25 supply and return vents, and vacuuming the grill covers barely touches the pathway behind them. We use brush agitation, negative-air extraction, and source removal to pull debris from the full length of the duct, not just the visible end.
Most Katy vent cleaning jobs run $180-$340 for register and boot cleaning when done as part of a full system service, or $280-$450 as a standalone vent-specific job in smaller homes. Homes with excessive construction debris or post-Harvey mold may fall outside this range until we camera the system.
Supply Vent Cleaning
Supply vents push conditioned air into your rooms, but in Katy they also push out whatever the builder left in the ducts. Drywall dust is the most common find in pre-2005 homes; post-2010 builds often have insulation scraps and sawdust. We remove each register, clean the boot, and run the Rotobrush to the main trunk.
Return Vent Cleaning
Return vents pull air back to the handler, and they’re the first place we look for separated collars and wall-of-return leaks. In Grand Lakes and Cinco Ranch, we’ve found returns pulling attic air directly through gaps in the flex duct, which means your system is cooling 150°F attic air instead of recirculated indoor air. Cleaning the return path and sealing those separations often drops the blower motor load measurably.
Air Duct Repair in Katy
Air Duct Repair in Katy is rarely about punctures or animal damage. The real culprit is heat-cycled flex duct that has sagged, separated at collars, or collapsed entirely after 15-25 years in attic spaces that routinely exceed 140°F. We see this pattern so predictably in Cinco Ranch, Grand Lakes, and Seven Meadows that we can often tell a homeowner the build year of their home by the type of failure we find. Repair costs in Katy typically run $280-$580 for collar reattachment and sag correction, or $650-$1,200 when multiple runs need replacement with properly supported flex or rigid metal transitions.
Every repair starts with a video inspection so you see the separation, the sag, or the debris blockage before we quote. The written price covers the repair and the cleaning that should accompany it, because sealing a duct without removing the debris inside just traps it.
Collar Separation Repair
Flex duct connects to the air handler and to branch takeoffs with mechanical collars. In Katy’s heat, the adhesive degrades, the zip ties crack, and the collar gaps open. We reseat, seal, and support each connection so the system pulls from the conditioned space, not the attic.
Sag and Collapse Correction
Builder-grade flex duct was hung with minimal support spacing, and gravity plus heat distortion creates low spots where condensation pools and debris collects. We add proper hangers, eliminate sags, and in severe cases replace collapsed sections with supported rigid duct or new flex rated for the application.
Trusted Brands We Service in Katy
Kestrel technicians carry Honeywell media air cleaners and Aprilaire whole-home filtration systems on our Katy trucks, and we stock the common filter sizes for the Guardman line used in many local new builds. If your system needs a filtration upgrade after cleaning, we can size and install it during the same visit. For the cleaning itself, we run Nikro negative-pressure extractors and Abatement Technologies HEPA filtration on every Katy job, with Rotobrush agitation tools sized for the 6-inch and 8-inch flex duct common in local homes. Parts and filters are available without a long wait because we keep Katy-specific inventory based on what we see most often in the field.
Common Air Duct Cleaning Problems We See in Katy Homes
- Construction debris from builder handover. In Katy’s 1993-2010s master-planned communities, crews routinely left drywall dust, sawdust, and even drywall screws inside supply and return ducts. The first time a new owner runs the system, that debris coats the blower motor and evaporator coil, reducing efficiency and circulating particles for years.
- Harvey-era moisture never remediated. Neighborhoods near Barker Reservoir and Buffalo Bayou tributaries flooded in August 2017. Many homeowners replaced flooring and drywall but never had their ductwork inspected. We still find mold colonies in flex duct insulation that have been releasing spores every cooling season since.
- Heat-cycled flex duct failure. Katy’s attic temperatures above 140°F for months each year degrade the plastic core of flexible ductwork. After 15-25 years, the duct sags at hangers, separates at collars, and develops wall-of-return leaks that pull unconditioned attic air into the system.
- DIY register-only cleaning. Homeowners vacuum the visible grills and assume the job is done. But the lint and debris pathway extends deep into attic flex runs where only negative-pressure source removal can extract it. Surface cleaning without mechanical agitation and controlled extraction just redistributes the problem.
Pricing for Air Duct Cleaning in Katy, TX
A typical full-system residential air duct cleaning in Katy runs $380-$650 for homes between 2,500 and 4,000 square feet, which covers the majority of Cinco Ranch, Grand Lakes, and Seven Meadows properties.

FAQs About Air Duct Cleaning in Katy
Yes, and possibly more urgently than an older home. Builders in Katy’s 2003-2007 construction wave rarely cleaned ducts before handover, and we’ve found drywall dust, insulation scraps, and even fasteners in systems that have been running for nearly 20 years. That debris has been recirculating since move-in day. Call (469) 972-3151 for a camera inspection and we’ll show you exactly what’s inside.
Katy’s average relative humidity stays above 70-75% most of the year, while Dallas regularly drops below 50%. That constant moisture means condensation forms inside flex duct insulation when AC cycles off, creating biological growth conditions far more aggressive than in drier metros. Cleaning here isn’t just about dust removal; it’s about breaking the mold growth cycle that humidity sustains.
Have the full flex duct run camera-inspected for moisture intrusion and mold migration, especially if you replaced drywall but never had HVAC-specific remediation. We’ve found active mold colonies in duct insulation seven years after Harvey, releasing spores every time the system cycles. If your home was in the flood zone and you never had dedicated duct inspection, that should be your next step.
Source removal means we dislodge debris at its point of attachment inside the duct wall using mechanical agitation, then extract it under negative pressure rather than pushing it deeper into the system or back into your living space. For Katy’s flex duct, this matters because the corrugated interior traps debris that air washing alone won’t release. The Rotobrush scrubs the wall; the Nikro extractor pulls the loosened material out through a sealed collection path.
Every 3-5 years for typical Katy homes, but sooner if you’ve had construction, flooding, or visible mold. New construction should be cleaned within the first year because of builder debris, and any home in the Barker Reservoir flood zone that hasn’t been inspected since Harvey should be evaluated regardless of schedule. Call (469) 972-3151 and we’ll recommend an interval based on your home’s specific history and what the camera shows.
