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.

AfterFast, Reliable Air Duct Cleaning Across Katy
Air duct cleaning for a typical Katy home runs $380-$650 for a full system, and every job starts with a written price before we touch a single panel. We’re CleanRun Duct Repair & Cleaning, and our crews serve Katy from our Houston office, carrying Rotobrush and Nikro equipment into neighborhoods from Cinco Ranch to Kelliwood to Canyon Gate. If your registers smell musty when the AC kicks on, or your 2000s-era flex duct hasn’t been opened since the home was built, call (346) 248-1474. We’ll schedule a video inspection, show you what’s actually inside, and put a flat price in writing before any work begins.
Why CleanRun Air Duct Cleaning The Woodlands Is Katy’s Preferred Air Duct Cleaning Company
We’ve been in this trade since 2013, and we’ve learned that Katy homeowners don’t buy duct cleaning from a script. They buy it from a technician who can explain why their specific house has a specific problem. Our Air Duct Cleaning team has documented photo records from over 52,000 homes, and we bring that same standard to every Katy job: before-and-after images of every duct run, delivered as part of the standard job record.
Katy customers find us because someone in their subdivision already used us. Word travels fast in master-planned communities. Our technicians are background-checked, uniformed, and identified by name before arrival under Haven Standard Clause 3: Verified Crews. Tomas Reyes, who leads CleanRun, set that policy in 2013 and hasn’t waived it once.
Dispatch and scheduling are coordinated from our Houston office, but crews are in Katy daily. We don’t quote over the phone without seeing the system, but we also don’t charge to look. Bring any competitor’s written estimate and we’ll put our number next to it for free under our Free Second Opinion policy.
Our Air Duct Cleaning Services in Katy
Residential Duct Cleaning
Katy’s housing stock is almost entirely 2000s-2010s production-built single-family homes on slab foundations, with flex ductwork routed through unconditioned attics. These systems sag over time from attic heat cycles, collect debris at low points, and grow mold where condensate pools. Our residential service puts the entire system under negative-pressure extraction (a sealed vacuum that pulls debris out without letting it escape into your home), agitates the duct walls with mechanical brushes, and delivers a Documented Photo Record of every run. In homes near the Addicks and Barker Reservoirs, we often find two moisture histories: chronic Gulf Coast humidity plus residual effects from Harvey-era flooding that pushed water into duct runs in Bear Creek Farms and Canyon Gate.
Commercial Duct Cleaning
Katy’s commercial buildings along I-10 and the Grand Parkway corridor, from medical offices to retail spaces, share the same humidity load as residential structures but with higher occupancy and more complex rooftop HVAC configurations. We clean commercial systems with Abatement Technologies HEPA-filtered negative air machines, sized to the cubic footage of the building. Every commercial job includes a written scope, a flat price per system, and the same 365-Day Done Right Promise we offer homeowners. We work after hours when needed to avoid disrupting your operation.
Supply Duct Cleaning
The supply ducts carry conditioned air from your air handler to each room. In Katy, these runs are where we most often find collapsed flex-duct liner, separated elbows, and mold at sag points. Our supply duct service includes video inspection of every accessible run, mechanical agitation to break loose debris, and source removal through negative-pressure extraction. We photograph the inside of each supply register before we start and after we finish. If the camera shows a liner that’s separated or a section that’s partially collapsed, we’ll tell you straight: replacement beats cleaning, and we’ll write that recommendation into the job record.
Return Duct Cleaning
Return ducts pull air back to the air handler for reconditioning. In Katy’s climate, these larger trunk lines often harbor the heaviest debris loads because they operate at lower pressure and don’t filter as finely as the supply side. Our return duct service cleans the full return path, from the wall or floor registers through the return plenum (the collection box that feeds the air handler) to the blower compartment. We inspect the evaporator coil and drain pan, because Gulf Coast humidity keeps these components wet enough to recolonize the whole system within weeks if they’re not addressed.
Full System Cleaning
A full system cleaning covers supply ducts, return ducts, the air handler cabinet, blower motor, evaporator coil, and drain pan. This is what most Katy homes actually need, especially those built during the 2000s master-planned-community boom in Cinco Ranch, Cross Creek Ranch, and Firethorne. Those homes are now 15 to 25 years old, and their original attic-mounted flex duct systems are hitting peak degradation simultaneously. A full system clean includes our complete equipment roster: Rotobrush mechanical agitation tools, Nikro HEPA-filtered negative air machines, and Guardsman inspection cameras. The price is flat per system, agreed in writing before we start.
Video Inspection
Every full system cleaning includes video inspection, and we also offer it as a standalone service for Katy homeowners who want to see inside their ducts before deciding on any work. The camera shows what a register check cannot: separated liner at elbows, collapsed sections, standing water, and microbial growth on duct walls. We deliver the footage as part of the Documented Photo Record. In early-2000s Cinco Ranch and Kelliwood homes, this inspection often reveals that the original flex duct has deteriorated past the point where cleaning provides value.

BeforeAfterTrusted Brands We Service in Katy
Our equipment roster includes Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, and Guardsman. These are trade-recognized brands, not proprietary tools with unverifiable claims. Katy customers can look up each manufacturer independently to confirm specifications. We maintain our equipment to manufacturer standards and replace consumables on schedule, because a HEPA filter loaded past its rated capacity doesn’t protect your indoor air, it just makes noise. Our technicians carry common replacement parts for air handler components we encounter in Katy homes, including drain pans and blower motor capacitors for systems that have been running continuously through humid summers.
Common Air Duct Cleaning Problems We See in Katy Homes
- Fogging “sanitiser” upsells that leave the actual problem untouched. Some operators mist a chemical into ductwork without any source removal. It kills surface organisms on dirty duct walls but leaves the biofilm, liner debris, and condensate-soaked insulation that caused the growth. It does nothing for a partially collapsed liner. We don’t sell fogging as a substitute for mechanical cleaning.
- Register-only cleaning that skips the air handler. Cleaning visible supply and return registers looks dramatic but misses the evaporator coil and blower motor, where Gulf Coast humidity keeps components wet enough to recolonize the whole system within weeks. Our full system service includes these components as standard.
- Attempting to clean flex duct that’s already failed structurally. In 2000-2005 era Cinco Ranch and Kelliwood homes, two decades of 140-150°F attic heat cycles plus Harvey-era moisture spikes have often separated the inner liner from the insulation wrap. Aggressive agitation on failing flex duct can tear it further. Our video inspection identifies this before any cleaning starts.
- Ignoring the dual moisture history in reservoir-adjacent subdivisions. Homes in Bear Creek Farms, Canyon Gate, and parts of Kelliwood sit on land affected by Addicks and Barker Reservoir flooding during Hurricane Harvey. Chronic coastal humidity plus a one-time flood event creates conditions a visual register check will never reveal. We use inspection cameras and moisture meters to assess these systems properly.
Pricing for Air Duct Cleaning in Katy, TX
A typical residential full system cleaning in Katy runs $380-$650 for a single HVAC system, depending on the number of duct runs, accessibility of the air handler, and what the video inspection reveals. Video inspection alone is $89-$149, credited toward the full cleaning price if you proceed. Commercial systems are priced by square footage and HVAC configuration; most Katy commercial jobs fall between $800 and $2,400.
What moves the price: homes with more than 12 supply registers, multiple air handlers, or ductwork requiring access through drywall. What does not move the price: we don’t charge per vent. One flat price per system, agreed in writing before work starts, under Haven Standard Clause 1. No per-vent pricing, no add-ons discovered after the truck arrives.

FAQs - Air Duct Cleaning in Katy
Katy’s position on the Gulf Coastal Plain keeps dewpoints above 70°F from May through October, so air handlers and flex duct surfaces stay wet almost continuously. This sustained humidity level, which inland Texas cities like Dallas or Austin do not see, means microbial growth starts sooner and is driven by condensation on cold duct surfaces rather than by outdoor dust. Addicks and Barker Reservoir flooding during Harvey also pushed water into duct runs in subdivisions like Kelliwood and Canyon Gate, leaving many homes with two separate moisture histories. Call (346) 248-1474 for a video inspection that will show whether your system has active growth.
No. Fogging kills surface organisms but leaves the biofilm, debris, and moisture-soaked insulation that caused the growth. It does not remove source material, and it does not fix separated or collapsed flex-duct liner. A genuine clean requires mechanical agitation and negative-pressure extraction to remove debris, followed by drying and verification. We don’t sell fogging as a substitute for source removal. If you’ve had moisture issues in your Katy home, we’ll inspect with a camera and write you a scope that addresses what we actually find.
It depends on what the camera shows. In a 2003 Cinco Ranch home off Cinco Ranch Boulevard, our tech pulled a supply register and found the original flex duct’s inner liner had separated at an elbow above the master bath, blowing attic insulation fibers into the supply stream. A camera inspection confirmed two more collapsed sections and visible mold at a low point where condensate had been collecting. We set the system under negative pressure with HEPA filtration, used agitation tools to break the liner debris loose, source-removed it, and wrote the homeowner a straight recommendation: replace the three failed runs rather than pay for another surface cleaning, because no vacuum will fix a duct whose liner is gone. We’ll give you the same honest assessment. Call (346) 248-1474.
A real cleaning puts the system under sealed negative pressure, mechanically agitates debris from duct walls, and source-removes it through HEPA filtration. It includes inspection of every accessible run with a camera, cleaning of the air handler, blower motor, evaporator coil, and drain pan, and delivery of a Documented Photo Record showing before-and-after conditions inside every duct. It does not include fogging chemicals as a substitute for debris removal, and it does not mean vacuuming only the registers you can see. Our full system cleaning in Katy follows this protocol on every job, with a flat written price agreed before we start.
Musty odors when the AC starts, visible discoloration around registers, or increased allergy symptoms when the system runs are common indicators. But the only way to know is to look inside. We offer video inspection as a standalone service in Katy, and we credit the inspection fee toward any cleaning work you proceed with. In reservoir-adjacent subdivisions and early-2000s master-planned communities, we often find problems that a homeowner had no way to detect from the living room. Call (346) 248-1474 to schedule.
