Fast, Reliable Air Duct Cleaning Across Katy
Air duct cleaning in Katy typically runs between $425 and $780 for a full single-family home, with most jobs completed in 4 to 7 hours. We serve every corner of the city, from Cinco Ranch to Old Katy, and we bring the same written-price commitment to a 1970s rancher on Mason Road that we do to a 2020 build in Firethorne. When you call (254) 347-2738, a live person answers, not a voicemail queue, and you’ll have a firm price in your hands before a technician ever pulls up to the curb.
Katy’s housing stock isn’t uniform, and neither are its duct problems. Older homes carry decades of accumulation in original metal ductwork. Newer master-planned communities have flex duct in the attic, which sags, collects condensation, and attracts lint and dust differently. That’s why a diagnostic approach matters here more than in most cities. We look before we clean.
Why Kestrel Air Duct Houston Is Katy’s Preferred Air Duct Cleaning Company
Kestrel Air Duct Houston is part of the Kingswell family of companies, founded in 2004, and every job operates under the Kingswell Guarantee. That means four specific promises: a written price before work begins, a defined arrival window we actually hit, a clean job site when we leave, and a written guarantee on the work with a free return visit if anything falls short within the guarantee period. Not a vague pledge. It’s in writing, and our crews treat it that way in Katy.
Dale Whitmore leads our team with a simple standard: a technician should never walk out the door until the homeowner understands what was done and has proof of it. The 365-Day Done Right Promise backs that standard. If a cleaning falls short within the guarantee window, we come back to Katy and make it right at no charge. Free second visit if the work fails, included in writing, not a courtesy we might extend depending on the day.
What Katy homeowners tell us they appreciate most is the phone call itself. Dispatch and scheduling are coordinated from our Houston office, but crews serve Katy locally, and the person who answers your call is a real human at any hour. You can book a full Air Duct Cleaning appointment, ask about our process, or question a price. No automated menu. No call center script.
Styles & brands we work with
HVAC Duct Cleaning in Katy
HVAC Duct Cleaning in Katy usually runs $425 to $780 depending on square footage, number of returns, and whether the system has ever been cleaned. The job involves brushing the interior walls of supply and return ductwork with a rotary agitation tool, then drawing loosened debris out with negative-air extraction. We also clean the trunk line, branch runs, the blower compartment, and the return plenum. Before any brush goes in, we run a camera through the system to check for crushed runs, disconnected joints, and condensation damage. That matters in Katy, where attic-installed flex duct is common and not always sloped the way it should be.
Supply and Return Duct Cleaning
Supply ducts push conditioned air into your rooms. Return ducts pull air back to the blower. Both need attention. In Katy homes built in phases, we regularly find supply runs that were never sealed correctly at the boot, allowing attic air and insulation to be pulled into the living space. Cleaning gives us a chance to spot those gaps.
Camera Inspection Before Cleaning
Katy has too many attic systems with sagging flex duct for us to clean blind. We run a small camera through the runs before the agitation tools ever start. That lets us identify crushed sections, water in low spots, or a disconnected joint behind a register. You get a straight answer about what’s in your ducts and what the fix costs, in writing, before work begins.
Vent Cleaning in Katy
Vent Cleaning in Katy is priced as part of the Air Duct Cleaning in Katy service, not as a separate per-vent charge. We clean every register, grille, and diffuser in the home as part of the whole-system job. When a homeowner asks about “vent cleaning,” they usually mean one of two things: visible dust buildup on the vent covers, or musty air pushing through the vents whenever the A/C runs. Both are solvered. The covers get scrubbed and wiped, and the ductwork behind them gets brushed and extracted.
What looks like a simple dirty vent often is not. In Katy’s humid climate, condensation inside flex ducts promotes mold and mildew growth, especially in attic runs. That smell comes through the vents even when the covers look clean. A camera inspection before cleaning tells us which situation you have, and the price on your written estimate reflects the actual work, not a guess.
Floor and Ceiling Register Cleaning
Katy homes have both floor registers on first floors and ceiling registers upstairs, depending on where the air handler sits. Floor registers collect pet hair, dropped food, and tracked-in debris. Ceiling registers in two-story homes collect dust and, oddly often, insect casings. We remove each cover, clean it, and wipe the surrounding boot before the interior duct cleaning begins.
After the Cleaning: Filtration Support
For Katy homeowners who want to stay ahead of dust between cleanings, we offer Honeywell and Aprilaire filtration products. A quality media filter on the return side traps more of what the blower pulls in. That’s a practical add-on, not a requirement, and the pricing for it is on the same written estimate.
Trusted Brands We Service in Katy
We service all major HVAC equipment brands in Katy homes, including Trane, Carrier, Lennox, Goodman, and Rheem. The duct cleaning process stays consistent regardless of the label on the condenser, but we keep local stock of common replacement items for Katy homeowners: flex duct sections, register boots, mastic sealant, and insulation sleeving. Our technicians run Rotobrush rotary brush systems to dislodge debris at the duct wall, and Nikro negative-pressure units to pull contaminants out. Abatement Technologies HEPA filtration captures loosened particles before they can enter the living space. These are professional-grade tools, not box-store shop vacs, and they make a measurable difference in how much actually leaves the system.
Common Air Duct Cleaning Problems We See in Katy Homes
- Sagging flex duct with condensation in attic runs. Katy’s heat and humidity create condensation inside attic flex duct, especially where the duct has sagged over a truss. The water sits in low spots, grows mildew, and sends musty air into the house every time the blower runs.
- Crushed or disconnected runs missed by standard cleanings. Homes built in phases, or homes where attic work was done by multiple contractors, often have flex duct that was stepped on, crushed by a stored box, or never connected correctly at the register boot. A camera inspection catches these before brushing starts.
- Internal corrosion in 1970s-1980s metal ductwork. Older parts of Katy have homes with original galvanized metal ducts. Decades of humidity and temperature swings cause internal rust. Cleaning them requires a gentler approach than flex duct, and sometimes replacement is the honest recommendation.
- Undersized returns causing blower strain and dust pull-in. Many Katy homes, especially in neighborhoods built quickly during growth years, have return ducts too small for the system. The blower works harder, pulls air from wherever it can, and dust gets drawn into the duct system from the attic.

AfterPricing for Air Duct Cleaning in Katy, TX
A typical full-system cleaning for a single-family Katy home runs $425 to $780. Homes under 2,000 square feet usually land between $425 and $550. Homes over 3,000 square feet, or homes with two air handlers, run $650 to $780. If a camera inspection finds crushed runs, disconnected joints, or duct sealing work that should be addressed, those repairs are priced separately in writing before any work begins. We do not quote a per-vent price and then surprise you with a bigger invoice after the van arrives. The written price covers the entire system, and that number does not change at the door. Call (254) 347-2738 for a free estimate on your Katy home. It takes a few minutes, and you’ll have a real number to work with.
What affects the final number: square footage, number of systems, accessibility of the duct runs, and what the camera inspection finds. A 2003 two-story in Williamsburg Colony off Mason Road with one system and accessible attic runs will be on the lower end. A 1978 rancher in Old Katy with metal ducts, internal corrosion, and a second system added later will be on the higher end. The difference is the condition, not the marketing.

FAQs About Air Duct Cleaning in Katy
Musty air after a cleaning usually means the cleaning addressed the inside of the ducts but missed the outside of the attic flex runs. In Katy’s humid climate, condensation forms on the exterior of sagging flex duct, and that moisture grows mildew that seeps into the airflow. The fix is not another cleaning; it’s re-sloping the duct, replacing insulation, or sealing leaks. We find this often south of I-10, where attic air handlers and flex duct are common. Call (254) 347-2738 and we’ll run a camera inspection to find the actual source.
Homes built before 2000 in Katy should have ducts cleaned every 3 to 5 years, but the real variable is whether the ductwork has ever been inspected. A 1985 metal duct system with internal corrosion needs more frequent monitoring than a 2015 flex system. If you have not had a camera inspection, the first visit should include one, because cleaning a compromised duct system without knowing its condition can make problems worse. We’re happy to inspect and give you an honest schedule based on what we see.
Our cleaning removes the debris, dust, and biological growth from the interior surfaces of the ductwork, but if mold has penetrated fiberglass duct liner or the duct itself is degraded, replacement is the only correct fix. We’ll tell you which situation you have, in writing, and the price for the right repair. We don’t sell a “mold cleaning” that amounts to brushing a duct that should be replaced.
A full cleaning for a typical Katy home runs $425 to $780. Duct sealing, if the camera inspection finds leaks at joints or register boots, adds $150 to $400 depending on how many runs need work. The combined price is on one written estimate, agreed before we start. No per-vent charges, no door-step revisions. Call (254) 347-2738 and we’ll give you a straight number for your home.
That smell usually means the dryer vent is connected into the return duct system, or a disconnected return run is pulling air from the wall cavity near the dryer vent. In Katy homes built in phases, return runs sometimes share a chase with dryer exhaust, and a loose joint lets that air cross over. A camera inspection traces the run and finds the leak before any cleaning starts. We’ll show you the footage and quote the fix.
