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 in Katy, TX
HVAC cleaning in Katy typically runs $350-$650 for a whole-system service, with most jobs completed in a single visit. CleanRun crews work throughout Katy from our Houston coordination office, and every job starts with a written price before any panel comes off. Call (346) 248-1474 for a free estimate.
Katy homes present a specific set of conditions: 15-to-25-year-old flex duct systems in unconditioned attics, Gulf Coast humidity that keeps evaporator coils wet six months a year, and the lingering effects of Harvey-era moisture in subdivisions near the reservoirs. Our crews document every duct run with before-and-after photos, and every quote is delivered in writing under Haven Standard Clause 1.
Why Katy Homes Are Different
Katy sits on the flat Gulf Coastal Plain with dewpoints above 70°F from May through October, meaning HVAC systems run almost continuously and attic air temperatures routinely exceed 140°F. That combination degrades flex-duct insulation wrap and inner liners faster than in drier climates.
The 2000s master-planned-community boom produced thousands of now-aging tract homes in Cinco Ranch, Cross Creek Ranch, and Firethorne with original attic-mounted flex duct that sags at low points and collects condensate. In Bear Creek Farms, Canyon Gate, and Kelliwood, Hurricane Harvey’s intentional reservoir flooding left moisture in ductwork and air handlers that many homeowners never fully remediated. Technicians regularly find 2000-2005 era flex duct with collapsed inner liners or separated elbows, turning what starts as a cleaning call into a repair conversation before the Rotobrush even spins up.
Our Main Katy Services
Homeowners in Katy call us most often for duct cleaning, dryer vent work, and duct repair. Each service has its own Katy page with full pricing and scope details.
Air Duct Cleaning in Katy
We clean the full supply and return network with negative-pressure extraction, photographing every duct run before and after. In Katy’s older subdivisions, we often find debris accumulation at sag points where flex duct has lost tension. Every job includes a written price upfront and a Documented Photo Record delivered before we leave. Air Duct Cleaning in Katy
Dryer Vent Cleaning in Katy
Lint buildup in dryer vents is a fire hazard and efficiency killer in Katy’s humid climate, where longer dry times get blamed on the weather instead of blocked airflow. We clear the full vent run from appliance to termination, test airflow with a manometer, and photo-document the obstruction found. Dryer Vent Cleaning in Katy
Duct Repair & Sealing in Katy
Disconnected joints, collapsed flex sections, and failed tape seals are common in Katy’s 20-year-old tract housing stock. We repair with mechanical fasteners and mastic, not duct tape, and pressure-test the system before calling the job complete. Duct Repair & Sealing in Katy

BeforeAfterHVAC Cleaning in Katy
Katy’s humidity keeps evaporator coils and blower assemblies perpetually damp from May through October, creating a film of biological growth that restricts airflow and degrades indoor air quality. Our HVAC Cleaning service targets the components that actually move and condition air, not just the ducts that carry it. In Cinco Ranch and Kelliwood homes with original 2000s equipment, we regularly find coils clogged to the point that airflow is reduced by a third.
Evaporator Coil Cleaning
Signs you need it
Ice formation on the coil, longer cooling cycles, or a musty smell when the AC first kicks on.
What it costs in Katy
Evaporator coil cleaning typically ranges $180-$320 in Katy.
How we do it
We remove the access panel, apply foaming cleaner to the fin pack, rinse with low-pressure water, and photograph the coil condition before and after.
Blower Cleaning
Signs you need it
Dust puffing from registers at startup, weak airflow at distant rooms, or a vibrating noise from the air handler.
What it costs in Katy
Blower assembly cleaning typically ranges $150-$280 in Katy.
How we do it
We pull the blower wheel and housing, clean each blade individually, vacuum the squirrel cage, and balance the assembly before reinstall.
What HVAC Cleaning Costs in Katy
| Item | Typical range in Katy |
|---|---|
| Evaporator coil cleaning | $180-$320 |
| Blower assembly cleaning | $150-$280 |
| Full HVAC system cleaning (coil + blower + cabinet) | $350-$650 |
How do I know if my coil is dirty or my refrigerant is low?
Ice on the coil usually means low airflow from dirt, while low refrigerant causes warm air from vents without ice. We inspect the coil with a borescope and check pressures; call (346) 248-1474 and we’ll put both diagnoses in writing.
Will cleaning my HVAC components lower my electric bill?
A dirty coil or blower can increase runtime by 15-30%, so restored airflow typically shows on the next billing cycle in Katy’s summer heat. We photograph the restriction found so you can see the cause yourself.
Air Quality & Sanitizing in Katy
Katy’s sustained humidity and Harvey-legacy moisture create conditions where mold colonizes duct interiors and air handler surfaces within a single season. Our Air Quality & Sanitizing service treats biological contamination with EPA-registered products applied through professional foggers, not consumer sprays that leave residue. In reservoir-adjacent subdivisions, we still find active mold in ductwork from 2017 flooding that was never properly remediated.
Mold Treatment
Signs you need it
Visible mold at registers, a persistent earthy smell when the system runs, or respiratory symptoms that worsen at home.
What it costs in Katy
Mold treatment for a typical Katy home ranges $400-$750.
How we do it
We HEPA-vacuum affected surfaces, apply an EPA-registered antimicrobial through a mechanical fogger to reach the full duct run, and verify with post-treatment photos.
UV Light Installation
Signs you need it
Repeated mold recurrence after cleaning, or a home in a high-humidity microclimate near the reservoirs.
What it costs in Katy
UV-C light installation at the coil typically ranges $350-$600 in Katy.
How we do it
We mount a UV-C lamp upstream of the evaporator coil, wire to the blower circuit, and show you the bulb replacement schedule.
What Air Quality & Sanitizing Costs in Katy
| Item | Typical range in Katy |
|---|---|
| Mold treatment (whole system) | $400-$750 |
| UV-C light installation | $350-$600 |
| Combined mold treatment + UV install | $700-$1,200 |
Is the chemical treatment safe for kids and pets?
We use EPA-registered antimicrobials labeled for HVAC application, with a dwell time and ventilation protocol that leaves no airborne residue. The product name and SDS are included in your job documentation.
How long does mold treatment take?
Most Katy homes need 3-4 hours for full HEPA vacuuming, fogging, and verification photos; we schedule morning slots so the system is clear by afternoon. Call (346) 248-1474 to book.
