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.

AfterAir Duct Cleaning Company in Katy, TX
Air duct cleaning in Katy, TX typically runs $320 – $590 for a full system on an average single-family home, depending on square footage, how many air returns the house has, and how long it’s been since the ducts were last touched. We’re Cardinal Air Duct Cleaning, part of the Relay Home Co. family, and we work differently: a written price before any work starts, a live trackable arrival window, and before-and-after photos of your actual ducts. If you’re in Katy and want a straight answer about your system, call (737) 727-2314.
Why Katy Homes Are Different
Katy’s housing stock runs from 1970s ranch homes in the original sections of Old Katy to brand-new builds in master-planned communities like Cinco Ranch, Cross Creek Ranch, and Firethorne. That spread matters a lot for duct work. The older homes often have galvanized steel duct runs wrapped in insulation that’s now 30 – 40 years old, and that insulation breaks down into dust that recirculates through the registers. The newer homes have flexible duct lines in hot attics, where the Texas summer pushes attic temperatures well past 130 degrees. That heat ages flex duct faster than anywhere in the country.
Katy’s clay-heavy soil and flat terrain mean most of the duct runs here go through the attic, not a basement, because basements are essentially nonexistent in this part of Harris and Fort Bend counties. So every Katy job is an attic job in the summer, and that shifts how long a proper cleaning takes and why we use containment units from Abatement Technologies to keep the work contained. Humidity is the other thing – Katy sits close enough to the Gulf that indoor relative humidity regularly rides above 60% in the warmer months, which turns ordinary dust inside ducts into a damp, clinging film. A blower-and-a-prayer cleaning won’t remove it. Rotobrush agitation with negative-pressure extraction will.
Our Main Katy Services
These are the three jobs Katy homeowners call us about most often. Each one has its own dedicated Katy page with full pricing and details.
Dryer Vent Cleaning in Katy
Katy dryer vents get hammered by the same humidity that affects air ducts: lint that would stay dry and loose in a drier climate turns heavier and sticker here, and it packs against vent walls faster. Long vent runs through attic space are common in Katy’s newer two-story homes, and every foot of that run adds resistance. We clean the full run from dryer to exterior termination, clear the wall cap, and verify airflow with a calibrated meter so you know the vent is actually clear when we leave. Full details on our Dryer Vent Cleaning in Katy page.
Air Duct Cleaning in Katy
Most Katy systems have 10 to 18 supply runs plus a return or two, and a standard cleaning covers every run we can access from the register and the plenum. We use Rotobrush rotary agitation to break debris loose from duct walls, then a Nikro HEPA negative-air vacuum to pull it out of the system. The HEPA filtration matters: it captures the fine clay dust Katy homes collect, rather than exhausting it back into the attic. See the full breakdown on the Air Duct Cleaning in Katy page.
HVAC Cleaning in Katy
HVAC cleaning in Katy means more than wiping the return grill. We open the air handler, clean the evaporator coil, clear the condensate pan and line, and sanitize the blower wheel and housing with an EPA-registered product. With Katy’s humidity and the amount of loam and clay dust that blows in from surrounding construction, coils here foul fast, and a dirty coil drives up cooling costs through the summer. The full scope and Katy pricing are on the HVAC Cleaning in Katy page.

Pricing for Air Duct Cleaning Company in Katy, TX
| Service | Typical range in Katy |
|---|---|
| Full system air duct cleaning (single system, up to 15 runs) | $320 – $590 |
| Each additional supply run beyond 15 | $18 – $25 |
| Each additional return drop | $45 – $65 |
| HVAC coil cleaning (evaporator, in-place) | $140 – $230 |
| Blower motor and wheel cleaning | $80 – $140 |
| Condensate drain line flush and clean | $55 – $95 |

| Dryer vent cleaning (two-story or long run) | $135 – $195 |
| Rooftop or difficult-access dryer vent termination | $155 – $225 |
What pushes a Katy price toward the top of those ranges is usually attic access: summer heat slows the work, long flex runs in newer homes take more time, and two-story homes in communities like Cinco Ranch or Firethorne often have more supply runs than older single-story Katy houses. Whatever the number is, it’s written down and handed to you before any tool comes off the truck, and it does not change at the door.

No. Air duct and dryer vent cleaning is an interior maintenance service, and no Katy HOA we’ve worked with, including those in Cinco Ranch, Cross Creek Ranch, and Firethorne, requires approval or a permit for it. The work happens inside your home and at your existing exterior vent termination, with no changes to the structure that would trigger an architectural review.
