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.

We’ve been cleaning ducts in Katy since 2004, and we know the difference between a 1978 ranch in Old Katy and a new build in Firethorne. That matters because the dust in your system isn’t generic, and the fix shouldn’t be either. Our Air Duct Cleaning team uses Rotobrush rotary agitation and Nikro negative-air machines to pull debris out at the source, not just blow it around. Whether you’re off Mason Road or out toward the prairie, we show up inside the window, price it in writing, and leave the site clean. That’s The Garrison Standard.

When you call (361) 326-5060, you talk to a person who can schedule you, not a robot who puts you on hold.
Air Duct Repair in Katy
Air Duct Repair in Katy addresses the torn, sagging, or disconnected ductwork that wastes energy and circulates attic air into your living space. In Katy’s humid subtropical climate, flexible ductwork and ductboard in attic spaces absorb moisture, weaken at seams, and sag over time. We see this constantly in 1970s and 1980s ranch homes in Old Katy, where original fiberglass ductboard has degraded after decades of summer heat. Repair costs in Katy typically run $200 – $500 for section replacement or resealing, and $800 – $1,500 for more extensive trunk line work. Every repair gets a written price before we start and is covered by our 365-Day Done Right Promise.
Sealing Leaky Duct Joints
Leaky joints pull humid attic air into your system, which is why your AC runs constantly in July but never quite cools the back bedrooms. We seal with mastic and metal-backed tape, not duct tape, and test airflow before we leave. A sealed system in Katy can drop your cooling load significantly during those six-month summers.
Replacing Collapsed Flex Duct
Flexible ductwork sags when hangers fail or when insulation gets waterlogged from condensation. We replace collapsed sections with properly supported new flex duct or upgrade to hard pipe where it makes sense. In master-planned communities with two-story homes, we often find crushed flex above the second-floor ceiling where the builder’s crew stepped on it during construction.
Ductwork Cleaning in Katy
Ductwork Cleaning in Katy removes the accumulated dust, pollen, mold spores, and construction debris that circulates through your HVAC system and back into your air. We use a two-step process: Rotobrush rotary brushes agitate debris off duct walls, while Nikro negative-air machines maintain suction so nothing escapes into your home. A typical whole-home cleaning in Katy runs $350 – $650 depending on system size and accessibility, with larger two-story homes or systems with multiple zones toward the higher end. We perform video inspection before and after so you see what came out.
Source Removal for Allergy Relief
Katy’s location on the Katy Prairie means open land, unpaved roads, and high pollen counts that load ducts with fine particulates. Source removal, the NADCA-standard method we follow, physically extracts this material rather than just disturbing it. For families dealing with seasonal allergies, this matters more than any air freshener or spray treatment.
Post-Construction Cleanout
New construction in Katy kicks up fine silt and clay that gets drawn into HVAC intakes during the build process. We recently serviced a 2019 two-story home in Firethorne where the builder’s construction dust had clogged the return ducts and blower motor. Using Rotobrush agitation tools and negative pressure under NADCA standards, we performed source removal on the supply and return ducts, then HEPA-vacuumed the air handler. The homeowner immediately noticed better airflow and less dust on the registers.
Trusted Brands We Service in Katy
We stock and install filtration and cleaning equipment from Honeywell, Aprilaire, and Abatement Technologies, the same brands commercial HVAC contractors specify for schools and medical facilities. For Katy homeowners, that means no waiting on special orders when your system needs a media filter upgrade or a UV light installation. We carry Honeywell whole-house media cabinets and Aprilaire MERV 16 filters that drop into existing return plenums. If your system needs a specific Abatement Technologies HEPA filtration add-on, we can source and install it without the three-week lead times you’ll hit ordering online. Our technicians train on each manufacturer’s specifications, so the install matches what the engineer intended.
Common Air Duct Cleaning Problems We See in Katy Homes
- Construction debris in new builds. Because Katy sits on the Katy Prairie, new construction often disturbs soil and vegetation, releasing fine silt and clay particles that get pulled into HVAC intakes during the building process. Many new homeowners call for duct cleaning within the first year to remove construction dust, a pattern that’s less common in older, established suburbs.
- Mold in humid attic ductwork. Katy’s long, muggy summers keep attic temperatures above 130°F and humidity high. When flexible ductwork or ductboard has even small tears, moist attic air infiltrates and creates ideal conditions for mold and mildew growth inside the system.
- Sagging flex-duct in older homes. Original flexible ductwork in 1970s and 1980s Old Katy ranch homes was strung with minimal support and cheap hangers. After forty years of heat cycling, it sags, creating low spots where dust and moisture collect and airflow drops to a trickle.
- Fine silt from unpaved roads. Rural properties around Katy, especially those on gravel or dirt roads near the prairie, load ducts with fine silt and clay that ordinary vacuuming misses. Without rotary agitation tools and negative pressure, that grit stays in the system and keeps recirculating.
Pricing for Air Duct Cleaning in Katy, TX
Whole-home air duct cleaning in Katy typically costs $350 – $650 for a single-system residential setup. Two-story homes with multiple zones, or systems with extensive flex-duct runs in the attic, run toward the upper end. Commercial duct cleaning for small office buildings or retail spaces in Katy starts around $800 and scales with square footage and system complexity.
We price by the system, not by the vent. That means one flat price per HVAC system, agreed in writing before we start. No per-vent add-ons, no “surprise, you need this extra service” at the door. What affects your specific cost: system size and number of returns, accessibility (crawl space vs. attic), contamination level (standard dust vs. construction debris or mold), and whether you add duct sealing or dryer vent cleaning to the same visit. We provide before-and-after photos of your own ducts, not stock images, so you see what you paid for. Call (361) 326-5060 for a free estimate.

FAQs About Air Duct Cleaning in Katy
Every 2 – 3 years for rural Katy properties on unpaved roads, compared to the standard 3 – 5 year interval for homes on paved streets in master-planned communities. Fine silt and clay from gravel roads loads ducts faster than typical household dust, and that grit abrades blower motors and heat exchangers over time. If you can wipe a visible film off your return grille every few weeks, you’re due. Call (361) 326-5060 for an exact quote, estimates are free.
Katy’s prairie soil is fine silt and clay that gets airborne during construction and drawn directly into HVAC intakes before the home is even occupied. Drywall dust, insulation fibers, and wood framing debris coat the blower motor and supply ducts, reducing airflow and forcing your system to work harder from day one. Builders rarely clean ducts before turnover, so a first-year cleaning removes this debris before it becomes compacted. Call (361) 326-5060 to schedule, we perform video inspection so you see what came out.
Yes, we clean ductwork in workshops, barn apartments, and detached guest houses with independent systems. These smaller systems often use the same flex-duct and ductboard as main residences, and they accumulate the same prairie dust, sometimes faster because they’re opened more frequently. We price outbuilding systems separately and can bundle them with your main house cleaning for efficiency. Call (361) 326-5060 to discuss your setup.
MERV 11 – 13 for most Katy homes near open land, with MERV 16 if someone in the household has severe allergies or asthma. MERV 8 catches basic pollen and dust but misses the fine silt particles that prairie winds carry. Higher MERV ratings do restrict airflow slightly, so we check your blower’s static pressure capacity before recommending an upgrade. We stock Honeywell and Aprilaire media filters in these ratings and can install the cabinet if your system uses a basic fiberglass slot. Call (361) 326-5060 for a filter assessment.
Yes, wood-burning stoves add ash particulates and creosote-laden air to your home’s circulation, which loads ducts faster and can leave oily residues on duct walls that standard dusting won’t remove. If your stove is tied into your central HVAC or even just shares the same living space, we recommend cleaning every 2 years instead of 3 – 5, and we use stronger agitation settings on the Rotobrush to break that residue free. We also inspect whether your return air pulls too strongly near the stove, which can create a negative pressure that draws smoke into ducts. Call (361) 326-5060 for a system evaluation.
