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
Air duct cleaning in St. Augustine typically costs $450 – $850 for a full system on a standard 2,000-square-foot home, with historic-district properties sometimes running higher due to non-standard duct routing. We serve every corner of St. Augustine: the coquina and wood-frame cottages downtown, the mid-century bungalows on Anastasia Island, and the fast-growing master-planned communities out toward Palencia and World Golf Village. If you’re breathing construction dust from a new build or mold spores from decades of salt-air humidity, call (980) 447-2498 for a written price before any work starts.
Why Linden Air Duct Cleaning Is St. Augustine’s Preferred Air Duct Cleaning Company
We know this city’s ductwork better than most because we see what it actually looks like when we open a plenum here. St. Augustine’s housing stock runs from 18th-century masonry to last year’s flex-duct installs, and each requires a different approach. Our technicians understand that a retrofitted system in Lincolnville routed through a crawlspace behaves nothing like a standard trunk-and-branch layout in a 2019 Palencia build.
Every tech who arrives at your door is background-checked, identity-verified, and shows a photo ID badge before stepping inside. We send you their name and photo ahead of the visit, so you know exactly who’s coming. Marcus Veale leads our team with a plain-spoken approach: we tell you what the job costs, what we’ll do, and what happens if something isn’t right. That’s the Threshold Standard we’ve operated under since 2004.
Air Duct Cleaning Services in St. Augustine
Air Duct Cleaning Services in St. Augustine mean more than vacuuming a few registers. A proper job involves negative-pressure extraction that pulls debris out of the supply and return runs, the plenum, and the air handler cabinet, with HEPA filtration capturing the fine dust so it doesn’t re-enter your living space. Homes here need it for two reasons that don’t cancel each other out: the salt-laden, humid air accelerates mold growth, and new-build construction dust settles in ducts before the first move-in.
Source Removal for New-Build Dust
In St. Augustine, the single most common problem we find in homes under two years old is gypsum and drywall dust coating the inside of flex ducts. Builders rarely clean duct runs after rough-in, so the first cooling cycle pulls joint compound fines into the blower motor. We use Rotobrush agitation tools under negative pressure with HEPA filtration to perform source removal on supply and return ducts, then seal the plenum and install a MERV 11 filter to catch what construction left behind.
Mold and Microbial Remediation
Flanked by the Atlantic and the Matanzas River, St. Augustine keeps ambient humidity near-constant, which means condensation forms inside ductwork surrounded by humid building cavities. We treat surfaces with EPA-registered antimicrobials from Abatement Technologies after mechanical cleaning, addressing the microbial colonization that a shop vac cannot touch. This is especially critical in historic-district homes where ducts were retrofitted into spaces never designed for them.

HVAC Duct Cleaning in St. Augustine
HVAC Duct Cleaning in St. Augustine covers the entire forced-air system: supply ducts, return ducts, the air handler, the blower wheel, and the plenum. A standard whole-system cleaning runs $450 – $850 for most St. Augustine homes, while commercial spaces and historic properties with difficult access points can reach $900 – $1,400. The price is written down before we begin, and it does not change after we’re inside.
Supply and Return Duct Cleaning
Supply ducts push conditioned air into your rooms; return ducts pull air back to the handler. Both collect debris: supply runs accumulate construction dust, skin cells, and pet hair, while return runs pull in whatever settles near your floor registers. In St. Augustine’s humid climate, return plenums are the first place mold takes hold, because they handle the warmest, most humid air in the system.
Video Inspection Before and After
We run a camera through your ducts before cleaning and again when we’re done, so you can see what was actually removed. In vacation rentals on Anastasia Island and throughout St. Johns County, the camera often reveals years of settled gypsum dust and sagging flex duct that no filter change ever addressed. You get the footage; you don’t have to take our word for it.
Trusted Brands We Service in St. Augustine
We work with the equipment already installed in St. Augustine homes, regardless of brand, and we carry replacement parts and filters for the systems we see most often here. Our technicians run Rotobrush and Nikro negative-pressure machines and stock air-quality products from Aprilaire and Guardsman, which means when we find a damaged filter rack or a leaking plenum during a cleaning, we can often address it that same visit. No waiting a week for a part to ship from Jacksonville or Miami.
Common Air Duct Cleaning Problems We See in St. Augustine Homes
- Builder-grade construction dust never removed at handover. Drywall fines and joint compound get pulled into the air handler and blower motor on the first cooling cycle because the ducts were never cleaned after rough-in. This is the single most common issue we see in Palencia, World Golf Village, and the western St. Johns County subdivisions.
- Historic-district systems retrofitted into impossible spaces. Coquina and wood-frame homes in the oldest parts of St. Augustine often have ducts running through crawlspaces, dropped ceilings, and closet chases never engineered for airflow. These systems hide debris for decades because access points are minimal and no one opens the plenum.
- Vacation rental HVAC neglect. Properties cycling through short-term tenants on Anastasia Island frequently go years between duct cleanings because maintenance schedules reset with every turnover. We regularly open return plenums in these rentals and find mold colonization and debris dating back to the last major renovation, which in older structures may have been fifteen or twenty years prior.
- Salt-air corrosion on metal fittings. St. Augustine’s coastal air degrades galvanized duct fittings and flex-duct outer jackets faster than inland Florida markets like western Jacksonville experience. Corroded fittings leak conditioned air into humid cavities, which compounds condensation and accelerates mold growth inside the system.

FAQs About Air Duct Cleaning in St. Augustine
Because construction dust from drywall, joint compound, and framing sawdust sits in the flex ducts from the day the builder finishes rough-in. On the first cooling cycle, that dust gets pulled into the blower motor and air handler cabinet. We pulled the return plenum on a six-month-old house in Palencia and found the flex trunk and branch runs coated in a fine white gypsum layer that had already dusted the blower wheel. A full source-removal cleaning, a sealed plenum, and a MERV 11 filter fixed it. Call (980) 447-2498 and we’ll camera-inspect your ducts before recommending anything.
No. In St. Augustine’s new-build corridor, three years is actually late. Builder-grade ducts are never cleaned after rough-in, so the first three cooling seasons have already cycled drywall fines through your system. A camera inspection costs nothing when you schedule a cleaning, and it shows you exactly what’s inside. For most new homes here, what we find is settled gypsum dust and sagging flex duct, not mold. But knowing the difference matters, and you can’t know it without looking.
Yes. Salt-laden air corrodes galvanized duct fittings and degrades flex-duct outer jackets faster than the inland suburbs experience. Add near-constant humidity between the Atlantic and the Matanzas River, and you get condensation forming inside ducts for roughly nine months of the year. That combination is why we recommend a camera inspection even on newer island homes: the ductwork may be fine, but the fittings and jacket condition are worth checking before problems compound. Call (980) 447-2498 and we’ll give you a written price for whatever the camera finds.
Source removal means we put the entire duct system under negative pressure and agitate debris off the duct walls with Rotobrush or Nikro tools, then capture it with HEPA filtration before it ever reaches your living space. A shop vac dragged register-to-register re-suspends construction dust and mold spores into the air you breathe, because there’s no containment and no HEPA capture. That’s not a cleaning; it’s a redistribution. The National Air Duct Cleaners Association standard requires negative pressure and HEPA filtration, and that’s the standard we work to on every job in St. Augustine.
Yes. We schedule between guest turnovers on Anastasia Island and throughout St. Johns County, and we’ll work around your booking calendar. For rental properties, we often recommend a camera inspection first, because we commonly find mold colonization and years of settled debris that no filter change ever addressed, and the footage gives you documentation for your own records. A written price before work starts and the 365-Day Done Right Promise apply to every rental property we clean. Call (980) 447-2498 to schedule around your next turnover.
