The West Bank of Jefferson Parish has absorbed more than its share of disaster. Harvey — one of the most populated communities on the West Bank — experienced significant flooding impacts from Hurricane Katrina and has seen recurrent flooding events in the decades since. For homeowners who’ve lived here through multiple flood events, the immediate work of recovery — gutting, drying, rebuilding — often takes priority over the longer-term concern of what happened to the duct system.
At AH-CHOO! Indoor Air Quality, we’ve been working in flood-affected communities across South Louisiana for 38 years. We know what flood contamination does to ductwork, we know how to document it, and we know how to fix it. Our NADCA-certified technicians have inspected and cleaned duct systems in hundreds of post-flood Harvey homes.
What Flooding Does to Your Duct System
Contamination That Stays Long After the Water Leaves
When floodwater enters a home, it doesn’t carry clean water. In South Louisiana, floodwater is a mixture of stormwater, street runoff, lawn chemicals, and — particularly in severe events — raw sewage and industrial contamination. That mixture coats every interior surface it touches, including the inside of your ductwork.
Even after a home is dried out and rebuilt, the ductwork tells a different story. Here’s what we typically find in post-flood Harvey homes that were never professionally cleaned:
Sediment and particulate buildup: Fine silt from floodwater dries into a powder coating on duct walls. When the HVAC runs, this particulate recirculates through every room in your home.
Microbial contamination: Flood water introduces bacteria, mold spores, and other biological material that colonizes duct surfaces. With South Louisiana’s ambient humidity providing ideal growing conditions, this contamination can expand significantly over time.
Sewage-associated organisms: In events where sewage backup occurred, ductwork may harbor fecal coliforms and other pathogens that standard cleaning products don’t address — requiring professional remediation with EPA-registered antimicrobials.
Structural damage: Flooded flex duct often loses its shape, creating sags and low spots that trap moisture and debris. Rigid ductwork may show corrosion or joint separation that wasn’t visible during the initial rebuild.
The Problem With “It Was Replaced After the Storm”
Many Harvey homeowners tell us their ductwork was replaced after Katrina or a subsequent flood event. That’s a good start — but it’s not the end of the story. Post-disaster duct installations sometimes introduced new problems:
- Flexible ductwork improperly supported or kinked during rushed installation
- Joints not properly sealed, allowing attic air to infiltrate conditioned spaces
- Insulation disturbed during flood remediation introducing fiberglass fibers into the duct system
- New ductwork installed over or near contaminated surfaces that weren’t fully treated
After 15–20 years in Harvey’s climate, even well-installed post-Katrina ductwork needs attention.
AH-CHOO!’s Approach to West Bank Homes
38 Years of Gulf South Experience
There are contractors who’ve learned South Louisiana duct work from a manual. Then there are contractors who’ve been doing it through hurricanes, floods, and decades of relentless humidity. We’re the second kind.
Our NADCA-certified technicians bring specialized knowledge of how Gulf South construction practices — slab-on-grade homes, raised foundations, attic-mounted air handlers, crawl space systems — interact with this climate. We don’t apply a one-size-fits-all process. We inspect first, document what we find, and tailor our approach to your home’s specific system and contamination profile.
What your Harvey duct cleaning includes:
- Full pre-cleaning camera inspection with documentation
- Negative pressure HEPA vacuum system connected to your main trunk
- Mechanical agitation of all supply and return ducts
- Air handler and accessible component cleaning
- Post-cleaning inspection and homeowner review
- Approximately 7 hours, one job scheduled per day
When Duct Cleaning Isn’t Enough: Mold Remediation
Harvey’s combination of flood history and persistent high humidity means mold findings are common in our West Bank inspections. Duct cleaning removes loose debris and particulates, but it doesn’t treat established mold growth — that requires remediation.
Our [mold remediation services](https://ahchooindoorair.com/mold-remediation) treat affected duct surfaces and HVAC components with EPA-registered antimicrobials. We document every finding with photos, explain the remediation plan before work begins, and provide post-remediation documentation that can be useful for insurance purposes or future property transactions.
If you’ve ever seen visible mold near your registers or smelled a persistent musty odor when your HVAC runs, don’t wait. Schedule an inspection and let us tell you exactly what you’re dealing with.
Commercial Properties on the West Bank
Harvey’s Westbank Expressway corridor includes a significant concentration of retail, industrial, and service businesses. Commercial HVAC systems in these properties run at higher duty cycles than residential systems and accumulate contamination proportionally faster.
AH-CHOO! provides [commercial duct cleaning services](https://ahchooindoorair.com/commercial-duct-cleaning) throughout Harvey and the West Bank. We work around your business hours to minimize disruption and provide the documentation that commercial property managers and compliance-sensitive businesses require.
Harvey Neighborhoods and Communities We Serve
Our West Bank service area covers all of Harvey, including the West Esplanade corridor, Oakwood area, Behrman neighborhoods, and the residential communities along the Harvey Canal. We also serve nearby [Marrero](https://ahchooindoorair.com/air-duct-cleaning-marrero-la), [Gretna](https://ahchooindoorair.com/air-duct-cleaning-gretna-la), and communities throughout Jefferson Parish West Bank.
