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 in Katy typically runs $450-$850 for a full residential system, and every CleanRun job starts with a written price before a single panel comes off. We’re the Air Duct Cleaning crew that homeowners in Cinco Ranch, Grand Lakes, and Cross Creek Ranch call when they want to see what’s actually inside their ductwork, not just hear a vacuum run for twenty minutes. Dispatch and scheduling are coordinated from our Houston office, but our crews serve Katy locally and know the difference between a 1997 tract home off Mason Road and a 2014 build in Firethorne.

Why CleanRun Air Duct Cleaning Katy Is Katy’s Preferred Air Duct Cleaning Company
We’ve been independently owned and operated under the Haven Standard since 2013. In that time we’ve served more than 52,000 homes, every one with a written price before work started and a Documented Photo Record when the crew left. That record matters especially in Katy, where the post-Harvey remediation gaps in neighborhoods near the Barker and Addicks reservoir flood pools have left hidden problems inside walls that surface only as musty odors or unexplained energy spikes.
Our technicians are background-checked, uniformed, and identified by name before arrival, Haven Standard Clause 3: Verified Crews. They carry professional-grade equipment from Rotobrush, Nikro, and Guardsman, brands you can look up independently before agreeing to any price. The 365-Day Done Right Promise backs every job in writing, not as a policy subject to manager approval but as a contractual obligation: if the work is not right, we make it right.
All calls are answered by a live person, 24/7. No phone trees, no callback forms that disappear into a queue.
Our Air Duct Cleaning Services in Katy
Residential Duct Cleaning
Katy’s master-planned communities, Cinco Ranch, Grand Lakes, Cross Creek Ranch, Firethorne, were built fast during the suburban expansion of the 1990s through the 2010s. Those homes are now 15-25 years old, and their builder-grade flexible ductwork is sagging, accumulating debris, and developing micro-tears where humid attic air infiltrates supply runs. Our residential service includes full source removal with agitation tools and HEPA filtration under negative pressure, not just a shop-vac at the register. We photograph every duct run before and after, and you receive that photo record as a standard deliverable.
Commercial Duct Cleaning
Commercial systems along I-10 and the Grand Parkway corridor, medical offices near Katy Mills, and retail spaces in the LaCenterra development face the same Katy Prairie humidity load as homes, but with higher occupancy and more aggressive HVAC cycling. We scale our negative-pressure extraction systems to match commercial plenum sizes, and we work after-hours to avoid disrupting operations. The same written-price-first rule applies: no invoice surprises after the work is done.
Supply Duct Cleaning
Supply runs are where the conditioned air reaches your rooms, and in Katy’s sprawling single-story layouts, these runs stretch across large, superheated attic spaces. Attic temperatures spike above 130-140°F in summer, creating a severe temperature differential across flex duct walls that promotes condensation and mold growth inside the runs. We clean supply ducts with mechanical agitation and negative-pressure extraction, then verify with camera inspection. If the joints are intact, source removal is usually sufficient. If the flex is torn or the insulation is water-damaged, we’ll show you the photo and quote Duct Repair & Sealing - Katy or replacement separately, never as a hidden upsell.
Return Duct Cleaning
Return ducts pull air back to the air handler, and in Katy’s long cooling season, they move enormous volumes of humid, pollen-laden air, heavy Bermuda grass and ragweed loads off the surrounding prairie. Return trunks and plenums collect the most debris because every cubic foot of air in your home passes through them repeatedly. We clean the full return path, including the plenum (the main distribution box connected to your air handler), and we inspect the blower wheel and evaporator coil. A dirty blower wheel recontaminates clean ducts within weeks, and in Katy’s climate, that recontamination happens fast.
Full System Cleaning
A true full system clean in Katy means more than registers and visible trunk lines. We clean supply ducts, return ducts, the plenum, the blower assembly, and the evaporator coil access area. We use Rotobrush mechanical agitation systems and Nikro negative-pressure HEPA extractors. The job concludes with a post-clean camera pass through every run, and you receive the photo record as part of your job documentation. Anything less, and you’re paying for vacuum noise while the real problem remains.
Video Inspection
Our video inspection service uses push-camera systems to document the interior condition of every duct run before we quote any work. In post-Harvey neighborhoods like Bear Creek Village and Canyon Lakes West, this is non-negotiable. Drywall was replaced and surfaces bleached in 2017-2018, but flex duct joints were often never fully inspected. We’ve found mold staining and debris trapped in low-hanging duct runs that have since been closed back up inside rebuilt walls and ceilings. The camera shows what no surface inspection can.

Common Air Duct Cleaning Problems We See in Katy Homes
- Condensation inside flex duct runs from extreme attic heat differentials. Katy’s flat Gulf coastal plain location pushes relative humidity above 85-90% routinely, and attic temperatures above 130°F create severe temperature differentials across duct walls. Moisture condenses inside the runs, and mold colonizes the interior duct wall where no register vacuum can reach.
- Post-Harvey duct contamination in reservoir-adjacent neighborhoods. The deliberate release of Barker and Addicks Reservoirs during Hurricane Harvey in 2017 inundated thousands of Katy homes. Even after surface-level remediation, ductwork can harbor residual mold, sediment, and microbial growth years later. Contractors who fogged systems without opening joints left problems that still surface as musty odors.
- Builder-grade flex duct sagging and tearing in 15-25-year-old homes. Cinco Ranch, Grand Lakes, Cross Creek Ranch, and Firethorne were built quickly with cost-optimized materials. Flex duct sags between supports, debris accumulates in low spots, and micro-tears at joints pull humid attic air into supply runs. The result is reduced airflow, higher energy bills, and persistent humidity issues the homeowner can’t locate.
- Blower wheel and evaporator coil recontamination after incomplete cleaning. Some contractors clean ducts but ignore the air handler. In Katy’s nine-month cooling season, a dirty blower wheel throws debris back into clean ductwork within weeks. A full system clean includes the blower assembly and coil access area, verified with amp-draw readings before and after.
Pricing for Air Duct Cleaning in Katy, TX

What moves the number: register count, duct material (flex vs. metal), accessibility (crawl space vs. attic), and whether the job requires repair or sealing in addition to cleaning. We do not quote per-vent pricing. One flat price per system, agreed in writing before work starts, Haven Standard Clause 1. Every estimate is free, and our Free Second Opinion policy means you can bring us any competitor’s written quote and we’ll put our number beside it.

FAQs - Air Duct Cleaning in Katy
The musty odor is almost always microbial growth on the interior duct wall, activated by airflow. In Katy’s climate, condensation inside flex duct runs is endemic, and mold colonizes the damp surface. A fogging ‘sanitiser’ masks the odor temporarily but does nothing about the growth. Source removal with mechanical agitation and negative-pressure extraction, verified with post-clean camera inspection, is the only permanent fix. Call (346) 666-7165 for a written estimate, estimates are free.
Most 2002 Cinco Ranch homes need cleaning first, then inspection to determine if replacement is warranted. Builder-grade flex duct from that era is now 20+ years old and often sagging or micro-torn, but many runs are still structurally sound. We start with video inspection to document the interior condition. If the joints are intact and the insulation is dry, source removal restores airflow and efficiency. If the camera shows torn flex or water-damaged insulation, we’ll quote repair or replacement separately with photos. Call (346) 666-7165 to schedule inspection.
Fogging deposits a chemical layer on the duct interior that may kill surface mold temporarily, but it does not remove the colony, the debris, or the moisture source. In Katy’s humidity, regrowth is rapid. Worse, fogging can leave residue that becomes airborne and irritates sensitive occupants. Source removal, physically extracting contamination with agitation tools and HEPA filtration under negative pressure, is the only method that addresses the actual problem. We do not offer fogging as a standalone service, and we do not upsell it after cleaning. Haven Standard Clause 1: written scope, no exceptions.
Katy’s relative humidity routinely exceeds 85-90%, and the Katy Prairie’s flat terrain traps moisture close to the ground. Attic temperatures above 130°F create severe temperature differentials across flex duct walls, producing condensation inside the runs that simply does not occur in drier markets. San Antonio’s Hill Country location brings lower humidity and greater diurnal temperature variation, meaning less attic condensation and slower microbial growth. Katy homes need more frequent inspection and more thorough cleaning protocols to match the environmental load. Our crews see the difference in camera footage every week.
Watch for musty odors that persist after filter changes, uneven cooling between rooms, and energy bills that spike without thermostat adjustment. In Bear Creek Village, Canyon Lakes West, and similar neighborhoods, 2017-2018 remediation often replaced drywall and bleached surfaces but never fully inspected flex duct joints. We’ve found mold staining and sediment trapped in low-hanging runs that were closed back up inside rebuilt walls. Video inspection is the only way to verify what happened inside the ductwork. If your home flooded and the ducts were not camera-inspected, that inspection is the first step. Call (346) 666-7165 to schedule.
