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, FL
Air duct cleaning in St. Augustine runs $300 – $600 for a typical single-family home, depending on system size and how long it’s been since the last cleaning. We’re Cardinal Air Duct Cleaning, part of the Relay Home Co. family founded in 2005, and we approach St. Augustine homes with one standard: a written price before any work starts, before-and-after photos, and a live arrival window you can track from your phone. Call (737) 727-2314 for a free estimate and an honest conversation about whether your ducts actually need cleaning.
Why St. Augustine Homes Are Different
St. Augustine is old. Not southern-old, but genuinely historic in ways that change how air ducts behave. Homes near the Plaza de la Constitución, along Aviles Street, and in Lincolnville often sit on raised foundations with crawlspaces that hold humidity. That moisture migrates into ductwork, and combined with the salt air moving off the Atlantic, it creates a sticky film inside ducts that drier inland cities simply don’t get. We see it on every job: a fine gray coating inside the return plenum that’s equal parts sand, salt, and HVAC condensation. Coquina-block construction, common in the older districts, reads very differently from the frame-and-stucco homes going up in newer subdivisions off State Road 16 and County Road 210.
Newer developments like Palencia, Murabella, and Entrada weren’t built with coquina, but they deal with their own issue: construction debris. Drywall dust and sawdust settle into ducts during the build, and many owners tell us nobody cleaned them after the drywallers left. We see it in almost every home built within the last decade. Whether your home predates Flagler’s railroad or just got its certificate of occupancy last spring, the ducts tell a story about St. Augustine that most homeowners never see until we hand them the before-and-after photos.
Our Main St. Augustine Services
People here call us for three things, and each has its own dedicated page for St. Augustine. Here’s what each involves and why it matters in this city specifically.
Dryer Vent Cleaning in St. Augustine
Lint builds up faster here than almost anywhere in Florida because St. Augustine runs the dryers hard through the humid season. The bigger issue is vent design. Older homes near the historic district often route dryer exhaust through attics or along long exterior walls, and every foot of that run collects lint that traps moisture. We clean the full vent path with negative-pressure extraction – that means the loosened debris goes straight into the vacuum, not back into your laundry room. Then we run an airflow test to confirm the vent is actually moving air. Full details are on our Dryer Vent Cleaning in St. Augustine page.
Air Duct Cleaning in St. Augustine
We use Rotobrush rotary brush systems paired with Nikro HEPA vacuums to clean supply, return, and main trunk lines without contaminating the home. What changes in St. Augustine is what’s inside the ducts – salt film from the ocean air, sand from Anastasia beaches tracked into homes along A1A, and the persistent humidity that lets dust stick to duct walls rather than blow through. Every job includes a written price before we touch anything and photo proof of the work afterward. The Air Duct Cleaning in St. Augustine page covers full pricing and process.
HVAC Cleaning in St. Augustine
HVAC cleaning here means the full system: evaporator coil, blower wheel, drain pan, and the plenums at both ends. In St. Augustine, coils run wet for most of the year, and wet coils trap whatever the ducts missed. The result is higher humidity inside and a system that works harder from May through October. We pull the access panel, show you the coil condition, clean it, and treat the drain line so it doesn’t clog mid-summer. For the full breakdown, see HVAC Cleaning in St. Augustine.
