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.
Air Duct Cleaning in Katy, TX
HVAC cleaning in Katy typically runs $380-$620 for a standard two-zone system, and every job starts with a written price before we touch a single panel. The master-planned communities that define this area, Cinco Ranch to Firethorne, built thousands of nearly identical homes between 1997 and 2012 with flex-duct systems now hitting peak failure age all at once. Katy’s chronic humidity and year-round AC runtime create conditions we don’t see in drier Texas markets, and the 2017 Harvey reservoir releases pushed moisture into ductwork that surface repairs often left untreated. We dispatch crews from our Houston office and serve Katy homes locally. Call (346) 421-3357 for a free estimate.
Why Katy Homes Are Different
Katy sits on the old Katy Prairie where average relative humidity rarely drops below 70%, and AC systems run 9 to 10 months per year. That chronic condensation inside flex duct accelerates mold and dust-mite allergen buildup far faster than in Dallas or San Antonio. The housing stock is unusually uniform: 2,200-4,000 square foot two-story tract homes built in rapid waves from the mid-1990s through the early 2010s, almost all with multiple HVAC zones and long duct runs that sag and collect debris at boot connections.
The 2017 Hurricane Harvey Barker Reservoir controlled releases flooded thousands of Katy homes that had never previously flooded. Moisture pushed directly into duct systems that, even after surface-level home repairs, were often never properly cleaned or mold-remediated. We still find evidence of this in homes off FM 1463 and Mason Road.
Katy’s expansive black-clay soils cause significant seasonal slab movement. Technicians routinely find flex duct boots that have partially pulled away from floor registers due to foundation shift, meaning conditioned air dumps into the subfloor cavity rather than the living space. This isn’t a cosmetic issue; it’s a measurable efficiency loss and a pathway for subfloor contaminants to enter the return side.
Our Main Katy Services
These are the three services Katy homeowners call about most. Each has its own dedicated Katy page with full pricing and scope details.
Air Duct Cleaning in Katy
We clean the full supply and return network in Katy’s large-footprint homes, including the plenum, the main trunk, and every branch run to the register. Our crews photograph the inside of every duct run before and after, so you can see the difference between actual negative-pressure extraction and shop-vac noise. We use professional-grade equipment from Rotobrush and Nikro, and every job concludes with a Documented Photo Record delivered as a standard deliverable. Air Duct Cleaning in Katy

Dryer Vent Cleaning in Katy
Dryer vent blockages are a leading cause of house fires, and Katy’s lint accumulation rates run high due to the extended drying cycles caused by humidity-saturated fabrics. We clean the full vent run from the back of the dryer to the exterior termination, measure airflow before and after, and provide a written completion record. Every technician is background-checked and uniformed under Haven Standard Clause 3: Verified Crews. Dryer Vent Cleaning in Katy

Duct Repair & Sealing in Katy
Foundation shift in Katy separates flex duct boots from registers and creates leaks at plenum connections that cost homeowners hundreds in wasted cooling each summer. We inspect with cameras, seal accessible leaks with mastic and metal-backed tape, and replace damaged sections with new flex duct sized to the original spec. All repair work carries the 365-Day Done Right Promise in writing. Duct Repair & Sealing in Katy

Before
AfterHVAC Cleaning in Katy

HVAC cleaning in Katy addresses the evaporator coil, blower assembly, condenser, and air handler, components that work harder here than almost anywhere in Texas due to 9-to-10-month cooling seasons and humidity that never lets up. The coil in a Katy home can accumulate enough biological growth in 18 months to measurably restrict airflow and raise energy bills, a timeline we don’t see in drier climates. Our HVAC Cleaning service is built for these conditions.
Evaporator Coil Cleaning
Signs you need it
Ice forming on the refrigerant lines, a musty smell when the AC cycles on, or cooling that can’t keep up on humid July afternoons in Cinco Ranch.
What it costs in Katy
Evaporator coil cleaning in Katy typically ranges from $280 to $450 depending on accessibility and contamination level.
How we do it
We remove the access panel, apply foaming cleaner to the coil fins, rinse with low-pressure water to avoid fin damage, and photograph the before and after condition for the job record.
Blower Cleaning
Signs you need it
Dust puffing from registers at startup, uneven airflow between rooms, or a blower motor running louder than when the system was new.
What it costs in Katy
Blower cleaning in Katy typically ranges from $180 to $320 depending on whether the blower assembly requires full removal.
How we do it
We power down the unit, remove the blower assembly, clean the squirrel cage and housing with compressed air and contact cleaner, balance the assembly, and reinstall with torque to manufacturer spec.
What HVAC Cleaning Costs in Katy
| Item | Typical range in Katy |
|---|---|
| Evaporator coil cleaning | $280 - $450 |
| Blower cleaning | $180 - $320 |
| Full HVAC system cleaning (coil + blower + condenser) | $380 - $620 |
How do I know my HVAC system was actually cleaned?
Every HVAC cleaning job in Katy includes a Documented Photo Record of the evaporator coil, blower assembly, and condenser before and after, delivered to you as a standard deliverable under Haven Standard Clause 2. You see what we saw. Call (346) 421-3357 to schedule.
Why does my AC smell musty in Katy humidity?
The coil and drain pan stay wet for months in Katy’s climate, supporting microbial growth that releases odor when the blower cycles on. Cleaning the coil, pan, and blower removes the source; sanitizing prevents rapid recurrence. Call (346) 421-3357 for a written quote.
Air Quality & Sanitizing in Katy

Air quality and sanitizing in Katy targets the microbial load that builds in duct systems running through 70% humidity 10 months a year, especially in Harvey-impacted homes where moisture entered wall cavities and duct boots. The 1997-2012 flex-duct stock in communities like Grand Lakes and Firethorne is now old enough that interior liner degradation traps contaminants the original smooth surface would have shed. Our Air Quality & Sanitizing service addresses this with measurable methods, not fragrance masking.
Mold Treatment
Signs you need it
Visible growth on register boots, a persistent earthy smell from vents, or family members with worsening allergy symptoms that improve when away from home.
What it costs in Katy
Mold treatment in Katy typically ranges from $450 to $850 depending on the number of affected duct runs and whether the plenum requires access.
How we do it
We apply an EPA-registered antimicrobial through the duct system under negative pressure, treat the plenum and accessible boots with contact spray, and provide lab-capable sampling documentation on request.
UV Light Installation
Signs you need it
Repeated coil contamination after professional cleaning, or a home in a Katy subdivision with chronic humidity issues and no whole-house dehumidification.
What it costs in Katy
UV light installation in Katy typically ranges from $380 to $650 depending on lamp wattage and whether the air handler requires structural modification for mounting.
How we do it
We mount a Honeywell or Aprilaire UV-C lamp in the supply plenum with a sight glass for visual verification, wire to the blower circuit for automatic operation, and provide the lamp replacement schedule in writing.
What Air Quality & Sanitizing Costs in Katy
| Item | Typical range in Katy |
|---|---|
| Mold treatment | $450 - $850 |
| UV light installation | $380 - $650 |
| Full air quality package (treatment + UV + filter upgrade) | $720 - $1,200 |
Is mold in my ducts common after Harvey flooding?
We still find untreated moisture damage in Katy homes where duct boots sat in shallow floodwater that wicked into flex duct liner; surface home repairs often missed this. A camera inspection shows the actual condition. Call (346) 421-3357 for a free assessment.
Do UV lights actually work in humid climates?
UV-C lamps prevent biological growth on the coil and in the plenum by breaking DNA bonds in mold and bacteria; in Katy’s humidity, they extend the effectiveness of physical cleaning but do not replace it. We size and position lamps to manufacturer spec for your air handler. Call (346) 421-3357 for details.
Brands We Service in Katy
We stock parts and service equipment from Honeywell, Aprilaire, and Abatement Technologies, with filter media and UV lamps held locally for same-week replacement in Katy-area homes. Most common Honeywell and Aprilaire whole-house media filters ship within 48 hours if not on the truck. our brands
