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.

Nassau Bay was purpose-built in the early 1960s for NASA Johnson Space Center workers, so virtually every home here is a 1960s-70s ranch or split-level whose original fiberglass duct board and early flex duct have spent 50+ years in Clear Lake’s tidal microclimate, making year-round mold colonization a near-constant threat rather than a summer-only problem. We’ve cleaned ducts in the ranch homes off Point Lookout, the split-levels near the marina, and the properties backing up to the lake itself. Each neighborhood has its own pattern of contamination, but they all share the same underlying pressure: decades of Gulf Coast humidity working its way into aging ductwork that was never designed to withstand it.
Why Morton’s Air Duct Cleaning Is Nassau Bay’s Preferred Air Duct Cleaning Company
We’ve been part of the Cedarwell family since 2005, and our Air Duct Cleaning in Nassau Bay reputation comes from showing up, protecting the home, and leaving proof behind. Our technicians wear shoe covers and lay drop cloths from the moment they walk in, because we know many Nassau Bay families are still working from home part-time and can’t afford a disrupted afternoon. Every job ends with a photo of the clean-up before the crew leaves, so you see exactly what was removed and how the space was left.
The 365-Day Done Right Promise backs every visit. If something isn’t right, we make it right. No transfer to a call center, no runaround. A live person answers our phone 24/7, and that includes evenings when you’re home from the Clear Lake commute and finally have time to think about that smell in the vents. Our background-checked, uniformed technicians work to the Cedarwell C.A.R.E. values, which means quiet tools during nap hours and pet-safe product choices where available. We know the dog is on the floor and the toddler might be down the hall.
Commercial Air Duct Cleaning in Nassau Bay
Commercial Air Duct Cleaning in Nassau Bay covers office suites near NASA Parkway, medical tenant spaces, retail strips along Upper Bay Road, and any commercial HVAC system that has been moving humid Gulf Coast air through metal ductwork for years. We inspect the full supply and return network, clean registers and diffusers, and remove buildup from blower assemblies and coils using professional-grade negative pressure systems. A typical commercial duct cleaning in Nassau Bay runs $800-$2,400 depending on square footage, system accessibility, and whether video inspection reveals post-Harvey contamination in under-slab returns. We provide a written price before any work starts, every time.
Office and Medical Tenant Cleaning
Medical offices and professional suites near the Nassau Bay commercial core need scheduled cleaning that doesn’t interrupt patient hours. We work early mornings and weekends, coordinate with building management for rooftop unit access, and document everything for lease compliance.
Kitchen Exhaust and Return Systems
Restaurant and food-service exhaust ducts in Nassau Bay’s commercial strip collect grease and humidity faster than inland locations. We clean the full hood-to-fan path and inspect fire suppression access points while we’re in the ceiling.
Air Duct Cleaning Services in Nassau Bay
Air Duct Cleaning Services in Nassau Bay start with a full-system inspection using video camera equipment, then move to agitation cleaning with HEPA-filtered negative pressure containment. We clean supply ducts, return ducts, trunk lines, and registers, and we pay special attention to the under-slab returns that are common in 1960s-era construction here. A typical full residential system cleaning in Nassau Bay runs $350-$650, with add-on dryer vent cleaning at $120-$180. Every quote is flat-rate per system, never per-vent, and we put it in writing before touching anything.
Residential Full System Cleaning
Our residential process covers every accessible duct segment. We seal off rooms to prevent cross-contamination, use Rotobrush agitation tools to loosen debris from fiberglass duct board without damaging it further, and capture everything with Nikro HEPA vacuums. For homes with original ductwork, we note any seams that have delaminated and may need sealing after cleaning.
Video Inspection and Documentation
We run cameras before and after cleaning so you see the condition inside your ducts. In Nassau Bay’s older homes, this often reveals the gap between what a homeowner assumed was clean and what 50 years of humidity exposure has actually created.

Trusted Brands We Service in Nassau Bay
We clean and service systems that use Honeywell, Aprilaire, and Abatement Technologies components, and we stock common replacement parts for Nassau Bay customers so we’re not ordering and returning. That means faster turnaround on jobs where a register damper has corroded shut or a media filter housing has warped from years of humidity cycling. Our Nikro and Rotobrush cleaning equipment is professional-grade, not rental-store level, and our technicians train on it specifically. If your system uses Aprilaire whole-house filtration or Honeywell zoning controls, we know how to work around them without disturbing settings. For commercial clients with Abatement Technologies HEPA air scrubbers already installed, we coordinate our cleaning protocol with your existing equipment.
Common Air Duct Cleaning Problems We See in Nassau Bay Homes
- Condensation-soaked fiberglass duct board. Homeowners along Clear Lake assume a wipe-down of the registers counts as cleaning, but the real problem is condensation-soaked fiberglass duct board inside the walls that never dries out between AC cycles. The material was standard in 1960s construction and it’s slowly breaking down.
- Post-Harvey under-slab return contamination. Post-Harvey homes that were dried out but never had their under-slab returns professionally cleaned keep recirculating silt and mold spores every time the blower motor runs. The floodwater may be gone, but the debris is still in the ducts.
- Dust loading on western-edge properties. Properties on the western edge of town with unpaved drive approaches and open lots pull in far more dust and pollen than the lakeside streets, so the same cleaning interval doesn’t fit both sides of the city. We adjust our recommendations based on where you are.
- Original flex duct collapse and restriction. Early-generation flex duct from the 1970s replacement cycle has become brittle and partially collapsed in many Nassau Bay attics, restricting airflow and creating dead zones where humidity pools. Camera inspection finds what a register check never will.

FAQs About Air Duct Cleaning in Nassau Bay
Homes on Clear Lake typically need cleaning every 2-3 years, not the 5-year interval that works for drier inland climates. The constant humidity exposure accelerates microbial growth inside duct board, and waterfront properties with minor insulation gaps see condensation year-round. Properties on the western edge with unpaved approaches may need more frequent service due to dust loading. Call (323) 918-4345 and we’ll assess your specific location.
It depends on condition, which is why we video inspect first. Delaminated or crumbling duct board needs replacement. Intact board with surface mold and debris can often be cleaned and sealed. We were called out to a 1965 split-level off NASA Parkway backing up to Clear Lake, where the homeowner swore the house smelled like wet attic every time the AC kicked on. Our tech ran a camera inspection through the supply and return ducts and found original fiberglass duct board delaminating with visible mold growth along the seams of the under-slab return, then used agitation tools and negative pressure with HEPA filtration to pull the debris out before sealing the gaps - the musty smell never came back after that cycle. We’ll tell you honestly what we find.
Remediation companies often dry walls and replace flooring but miss under-slab return ducts that took on floodwater. Those ducts keep recirculating Harvey-era silt and mold spores every time the blower runs. We see this specifically in Nassau Bay’s low-lying utility areas. A camera inspection will show you exactly what’s still in there. Call (323) 918-4345 for a free estimate.
We inspect every accessible supply and return segment with video, note the condition of fiberglass duct board or flex duct, check under-slab returns for post-flood debris, measure airflow at registers before and after, and photograph the clean-up before we leave. Shoe covers and drop cloths are on from the first step inside. We also ask about pets, kids’ nap schedules, and any areas you want us to avoid.
Yes. We clean office suites, medical tenants, retail spaces, and restaurant exhaust systems throughout Nassau Bay’s commercial corridors. Commercial jobs get the same written price upfront, the same 365-Day Done Right Promise, and the same documentation. Systems are typically larger and may require rooftop access, which we coordinate with building management. Call (323) 918-4345 to discuss your building.
