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.

AfterAir Duct Cleaning Company in St. Augustine South, FL
Air duct cleaning in St. Augustine South costs between $350 and $650 for a typical single-story concrete block home, and most jobs take three to five hours from setup to final walkthrough. The price reflects something specific to this community: homes here sit against tidal marsh, and the salt-laden air leaves a grayish-green film inside ductwork that plain vacuuming won’t remove. Morton’s Air Duct Cleaning has worked these marsh-facing streets long enough to know exactly what that film is and how to treat it. Call (323) 918-4345 for a written quote before any work begins.
Why St. Augustine South Homes Are Different
St. Augustine South sits on a low-lying peninsula bordered by tidal marshes along the Matanzas River and the Intracoastal Waterway. That geography does two things to every HVAC system in the neighborhood. First, relative humidity above 80% is routine even in January, and the marsh air pushes organic particulate counts higher than you’d find a mile inland. Second, most homes here are single-story concrete block builds from the mid-1960s through mid-1980s, with original or early-replacement flex duct running through hot, poorly ventilated attic spaces.
Those two facts collide in a way we see on nearly every St. Augustine South job. The aging flex ducts develop micro-tears and joint separations, and the unconditioned attic air they pull in is loaded with humidity, mold spores, and salt particulates. The result is a distinctive grayish-green biofilm coating the duct interiors, especially in homes within a few blocks of the marsh-facing streets. That coating requires antimicrobial treatment beyond standard vacuuming, which is why the work here differs so much from a typical inland duct cleaning. AC systems run almost eleven months a year in this climate, so the ducts never really dry out between cycles.
Our Main St. Augustine South Services
Two services account for nearly every call we take from St. Augustine South homeowners. Each has its own page with full pricing, local details, and what to expect from start to finish.
Air Duct Cleaning in St. Augustine South
Full-system Air Duct Cleaning in St. Augustine South starts with a camera inspection of the supply and return runs, because in this neighborhood the question isn’t whether the ducts are dirty but whether the flex duct joints are still sealed. We clean every register, the main trunk lines, and the return plenum with Rotobrush agitation equipment paired with a HEPA-filtered negative air machine, then apply an antimicrobial treatment to address the marsh-air biofilm. Shoe covers and drop cloths go down before equipment comes through the door, and you get a written price before the work starts, protecting floors and furniture throughout the visit.
Dryer Vent Cleaning in St. Augustine South
St. Augustine South dryer vents run short distances in most of these 1960s-era homes, but the coastal humidity compact the lint into a damp mat that resists the standard brush pass. Our Dryer Vent Cleaning in St. Augustine South service includes the full run from dryer connection to exterior vent cap, a flow test before and after, and removal of any bird or debris blockage at the exterior termination. If the vent cap is rusted through from salt air, which happens regularly this close to the Matanzas River, we’ll point it out and can replace it on the spot. The whole job usually takes under an hour, and you’ll see the before-and-after airflow numbers on your written service record.
