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 Company in St. Augustine, FL
Air duct cleaning in St. Augustine runs $350 – $650 for a typical single-system home, with most jobs completed in one visit. What separates St. Augustine from inland Florida markets is the combination of extreme humidity, salt-laden air, and a housing stock that spans four centuries, from Spanish Colonial plaster walls to modern Anastasia Island builds. We dispatch crews from our Miami office and serve St. Augustine homes with the same equipment we’d use on a commercial job: Rotobrush rotary systems, Nikro negative-air machines, and filtration from Aprilaire and Abatement Technologies. Call (361) 326-5060 for a written estimate before any work starts.
Why St. Augustine Homes Are Different
St. Augustine’s humid subtropical climate hits ductwork harder than almost anywhere else in Florida. Salt air from the Atlantic accelerates corrosion on metal components, while year-round humidity above 70% creates ideal conditions for mold and mildew inside supply and return lines. In the historic downtown, we regularly find standing water in crawlspace ducts after king tides, and that musty odor locals recognize is often the first sign a homeowner calls about.
The housing stock compounds the challenge. Spanish Colonial and Victorian homes near St. George Street have retrofitted HVAC systems squeezed into spaces never designed for forced air, with original plaster walls that shed fine particulate into ductwork. On Anastasia Island and the mainland, mid-century ranches and newer construction present their own issues: fiberglass duct board that degrades in humidity, and flex duct runs that sag and trap debris. Our crews are trained to navigate fragile historic structures without damage, and to spot the moisture intrusion patterns that are specific to this coastline.
Our Main St. Augustine Services
Most St. Augustine homeowners call us for one of three jobs, each with its own page and pricing:
Air Duct Cleaning in St. Augustine
We clean the full supply and return system with a Rotobrush rotary brush and Nikro negative-air machine, pulling debris out rather than pushing it deeper. In St. Augustine, we pay special attention to mold-prone sections near crawlspace entries and attic hatches where humidity collects. Every job gets a written price before we start and before-and-after photos of your own ducts. Air Duct Cleaning in St. Augustine

Dryer Vent Cleaning in St. Augustine
Lint buildup in dryer vents is a fire hazard anywhere, but in St. Augustine’s salt-air environment, the metal venting corrodes faster and catches more debris. We run a rotary brush through the full line to the exterior cap and measure airflow before and after. If your dryer takes two cycles to finish a load, the vent is likely restricted.

Duct Sealing in St. Augustine
Leaky ducts pull humid, unconditioned air from crawlspaces and attics, overworking your AC and feeding mold growth. We seal joints and seams with mastic and fiberglass mesh, then pressure-test the system. In older St. Augustine homes with original plaster and retrofit ductwork, sealing often delivers more comfort improvement than equipment replacement. Duct Sealing in St. Augustine
