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.

AfterFast, Reliable Air Duct Cleaning Across St. Augustine South
Air duct cleaning in St. Augustine South typically runs $350-$650 for a complete residential system, with most jobs scheduled within a few business days and completed in a single visit. Our crews know the area well, from the marsh-facing streets off Marsh Point Drive to the concrete-block neighborhoods lining State Road 312, and we coordinate dispatch through our Miami office to reach St. Augustine South homes without the delays that come from out-of-town operators.
We’ve been serving families here since 2005, and we understand what St. Augustine South’s coastal humidity does to duct systems. Your AC runs nearly eleven months a year in this environment. Salt-laden air from the Matanzas River tidal marshes seeps into unconditioned attics, and aging flex ducts in those 1960s-1980s homes pull that humid, spore-laden air straight into your supply stream. That’s not a scare tactic. It’s what we find on job after job. Call (323) 918-4345 for a free estimate, and we’ll give you a written price before any work starts.

Air Duct Repair in St. Augustine South
Air Duct Repair in St. Augustine South addresses the micro-tears, joint separations, and water damage that plague aging flex duct systems in this area’s 1960s-1980s housing stock. When attic humidity stays above 80% for months and salt-marsh air infiltrates through gaps, duct material degrades faster than manufacturers expected. Repair work here often involves sealing or replacing sections of flex duct, reconnecting separated joints with proper mechanical fasteners, and testing static pressure to confirm the system isn’t pulling unconditioned attic air into your living space. Most residential repairs in St. Augustine South fall between $200-$500 for localized fixes, with full duct replacement running $1,500-$3,500 depending on system size and attic accessibility.
When Repair Beats Replacement
Not every damaged duct needs tearing out. Isolated micro-tears in otherwise sound flex duct, separated joints at plenum connections, and small sections with surface mold but intact insulation can often be sealed, reinforced, and returned to service. We document everything with video inspection so you see what we see before deciding.
Post-Flood Damage Assessment
After water intrusion, the question isn’t whether the duct looks dirty. It’s whether the water reached the insulation layer. Saturated insulation can’t be cleaned, it must be replaced, and we document this distinction with camera footage that insurers accept. On a job off Marsh Point Drive, our tech pulled a supply register and found the flex duct interior coated in a grayish-green film, the classic marsh-air biofilm. Using camera inspection and agitation tools under negative pressure with HEPA filtration, we source-removed the biofilm from the supply and return ducts, treated the air handler, and documented the pre- and post-cleaning footage for the homeowner’s flood-insurance claim after the previous season’s storm surge.
Ductwork Cleaning in St. Augustine South
Ductwork Cleaning in St. Augustine South means more than vacuuming out dust. The coastal humidity, salt-laden marsh air, and near-constant AC operation here create a unique contamination profile that standard cleaning protocols often miss. A proper job uses source-removal agitation under negative pressure, HEPA filtration to prevent recontamination, and, in marsh-adjacent homes, antimicrobial treatment for that distinctive grayish-green biofilm. Typical residential ductwork cleaning in St. Augustine South ranges from $350-$650 for a full system, with larger homes or heavily contaminated systems toward the upper end. Commercial systems start around $800 and scale with square footage and HVAC complexity.
Source Removal vs. Surface Wiping
We don’t wipe down registers and call it done. Our Rotobrush and Nikro equipment agitates debris from duct walls while powerful negative-pressure collection prevents it from settling elsewhere in your home. This matters especially in St. Augustine South, where salt particulates and organic debris bond more stubbornly to duct surfaces than ordinary household dust.
The Marsh-Air Biofilm Protocol
Homes within a few blocks of the Matanzas River marsh consistently show that grayish-green coating inside ducts. Standard vacuuming removes visible material but leaves spores viable. Our protocol adds EPA-registered antimicrobial treatment to the supply and return trunks after source removal, significantly reducing recolonization risk. This step is rarely needed a mile west toward US-1, but here it’s often essential for lasting results.
Trusted Brands We Service in St. Augustine South
We clean and service ductwork connected to all major air handler and HVAC brands, with particular familiarity in St. Augustine South for Honeywell, Aprilaire, and Abatement Technologies components. These brands appear frequently in the 1990s-2010s system replacements common in this area’s housing stock, and we stock common fittings, filters, and antimicrobial treatments to avoid delays. Our Nikro and Rotobrush equipment interfaces with standard duct dimensions found in local concrete-block construction, and we carry adapters for older or non-standard plenum connections. If your system uses Aprilaire media filters or Honeywell electronic air cleaners, we inspect and document their condition as part of every full-system cleaning, since coastal humidity degrades filter media faster than inland climates. Parts availability and our Miami-coordinated inventory mean most St. Augustine South jobs need no return visit for materials.
Common Air Duct Cleaning Problems We See in St. Augustine South Homes
- Grayish-green biofilm in marsh-adjacent homes. Ducts within blocks of the Matanzas River develop a distinctive salt-marsh coating that requires antimicrobial treatment beyond standard vacuuming. Skipping this step leaves mold spores to recolonize within months.
- Micro-tears in aging flex duct pulling humid attic air. The 1960s-1980s flex duct systems common here degrade at connection points and along runs, creating negative-pressure leaks that draw unconditioned, spore-laden attic air directly into your supply stream.
- Post-storm water damage masked by surface cleaning. After flood events, some contractors clean visible mold without camera-inspecting for saturated insulation or structural damage, setting up homeowners for system failure and denied insurance claims later.
- Mold colonization after rainy season peaks. June through September attic temperatures and humidity simultaneously peak in St. Augustine South, creating near-ideal conditions for duct interior mold growth that becomes noticeable as musty odors by October.

FAQs About Air Duct Cleaning in St. Augustine South
It depends on whether water reached the insulation layer. Surface water and minor intrusion can often be addressed with NADCA-standard source removal, antimicrobial treatment, and thorough drying, but saturated flex duct insulation must be replaced, not cleaned. We camera-inspect every post-flood system to document which sections are salvageable and which require replacement, providing footage that insurers accept. Call (323) 918-4345 to schedule an assessment.
The grayish-green biofilm is a signature of salt-marsh air infiltration, unique to homes near the Matanzas River and Intracoastal Waterway tidal marshes. Salt particulates, organic debris, and persistent humidity combine to create conditions that don’t occur a mile or two inland toward US-1. Standard vacuuming removes visible material but leaves viable spores; lasting results require antimicrobial treatment specific to this contamination type.
Schedule inspection within one to two weeks after water intrusion, once visible flooding has receded and electrical systems are safe to operate. Delaying allows mold colonization to establish, while rushing before proper drying can spread contamination. We’ll assess whether your system needs immediate attention or can wait for complete structural drying.
Yes, every post-flood assessment includes dated, geotagged video inspection footage showing pre-cleaning condition, work performed, and post-cleaning verification. We provide this documentation in formats accepted by major insurers, and we’ve supported numerous St. Augustine South homeowners through claims after seasonal storm surge events.
