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.

HVAC cleaning in St. Augustine South typically runs $325 – $585 for a standard single-system home, and the biggest factor is whether your evaporator coil and blower are included. We’re Cardinal Air Duct Cleaning, part of the Relay Home Co. family, and our HVAC Cleaning team works in St. Augustine South every week. If your supply registers smell musty or your AC runs longer than it used to, call (737) 727-2314 and we’ll give you a written price before any work starts.
St. Augustine South sits on the Intracoastal with a high water table, and that changes the job. Most homes here are slab-on-grade, which means long flex duct runs that rarely dry out between cooling cycles. We know the difference between a dusty system and a moisture problem, because we see both every week off Shore Drive, Kings Road, and the side streets running toward the marsh.
Why Cardinal Air Duct Cleaning Is St. Augustine South’s Preferred HVAC Cleaning Company
Omar Haddad runs our St. Augustine South operation, and he’s built the crew around one standard: show up with a plan, a name, and a price that doesn’t move. Homeowners in St. Augustine South tell us the same thing over and over. They called someone else first, got a teaser number on the phone, and watched the invoice climb once the van was in the driveway. That doesn’t happen with us. You get a written price before a single duct is touched.
Our technicians are background-checked, uniformed, and carry professional-grade equipment, not truck-mounted shop vacs. We run Rotobrush agitation systems, Nikro HEPA vacuums, and Abatement Technologies containment units on St. Augustine South jobs. Every booking comes with The Relay Standard: a live arrival window you can track from your phone, before-and-after photos of your own ducts, and a digital invoice payable by link. Omar answers calls directly when he’s not on a job, and a live person picks up 24/7.
We also back every HVAC cleaning in St. Augustine South with the 365-Day Done Right Promise. If the work isn’t right within a full year, we come back and correct it at no charge. That’s the longest satisfaction window in the trade, and it applies to every booking without exception.
AC Coil Cleaning in St. Augustine South
AC Coil Cleaning in St. Augustine South means cleaning both the evaporator coil and the condenser coil, and in this city the evaporator coil is usually the real problem. Slab-on-grade homes here often have oversized condensate pans, and when the coil sits damp against a dirty pan, it becomes a breeding ground for microbial growth. That’s the musty smell coming through your vents, not dust in the ductwork.
We include coil cleaning as part of a full HVAC cleaning, and we quote it as one flat price per system. For a typical St. Augustine South home, expect $125 – $225 for the evaporator coil and $90 – $160 for the condenser coil when booked as part of a full cleaning. We never price per vent.
Evaporator Coil Cleaning
The evaporator coil sits inside the air handler and collects condensation every time your AC runs. In St. Augustine South’s humidity, that coil stays wet longer than it does inland, which means more organic buildup and faster airflow restriction. We remove the access panel, apply a professional coil cleaner, and rinse the coil so air moves through it cleanly.
Condenser Coil Cleaning
The condenser coil lives outside, exposed to St. Augustine South’s salt air and oak pollen. Salt film on the coil fins reduces heat transfer, which forces the compressor to work harder and shortens its life. We wash the coil with a low-pressure rinse and fin-safe cleaner, then check the refrigerant lines while we’re there.
AC Cleaning in St. Augustine South
AC Cleaning in St. Augustine South goes beyond the ducts. It covers the entire air handling system: the blower wheel, the blower housing, the evaporator coil, the condensate pan, and the return plenum. When we clean the whole system, the air moving through your ductwork actually stays clean, instead of picking up debris from a dirty blower the moment we leave.
A full AC cleaning in St. Augustine South runs $325 – $585 for a typical single-system home. That includes the supply and return ducts, the blower, the coil, and the condensate pan, with before-and-after photos of every component. We hand you the price before work starts, and it does not change at the door.
Blower Cleaning
The blower wheel pushes conditioned air through your whole duct system. When the wheel blades are caked with dust and mold, the system moves less air, and rooms at the end of long flex runs, which are common in St. Augustine South additions, get weak airflow. We pull the blower, clean each blade, and reinstall it with the housing wiped down.
Air Handler Cleaning
The air handler is the cabinet that holds the blower, the coil, and the condensate pan. In St. Augustine South slab homes, the air handler is often tucked into a closet or garage corner where humidity collects. We clean the interior surfaces, clear the condensate line, and make sure the pan drains properly before putting it back together.
Trusted Brands We Service in St. Augustine South
We service and clean all major HVAC brands in St. Augustine South, including Carrier, Trane, Lennox, Rheem, Goodman, and Amana, plus mini-split systems from Mitsubishi and Daikin.

Because our St. Augustine South crew runs these systems daily, we stock common filters, condensate tablets, and coil cleaners locally. No waiting on parts that should have been on the truck.
Common HVAC Cleaning Problems We See in St. Augustine South Homes
- Condensation pooling in sagging flex ducts. Long flex runs to additions, typical in St. Augustine South slab homes, droop over time and collect water in low spots. That standing water feeds mold growth that no amount of surface dusting fixes.
- Mold on the evaporator coil and condensate pan. Oversized condensate pans on St. Augustine South homes hold water longer, and the damp coil above them becomes a microbial source. Cleaning the ducts without the coil leaves the smell right where it started.
- Blower wheels caked with humid-weather buildup. St. Augustine South’s coastal humidity bonds dust to the blower wheel faster than dry inland air does. A dirty blower reduces airflow, especially to the farthest bedrooms.
- Return ducts pulling air from damp crawl spaces or garages. Some older St. Augustine South homes have return paths that draw humid air from unconditioned spaces. We check return placement and seal gaps where outdoor air leaks into the system.

FAQs About HVAC Cleaning in St. Augustine South
Every four to six years is appropriate for most St. Augustine South homes, but homes with pets, recent renovations, or persistent humidity issues may need it every three years. If you’re seeing visible mold on the vents or smelling musty air when the AC kicks on, don’t wait for a calendar date. Call (737) 727-2314 and we’ll do a camera inspection before recommending cleaning, so you’re not paying for work that isn’t needed yet.
Per-vent pricing is common because it makes a quote sound small over the phone, then balloons once the technician counts the actual vents in your St. Augustine South home. Long flex runs and added-on rooms mean more vents than the original quote assumed. We quote one flat price per system based on the real duct layout, written down before we start. That number doesn’t change.
At the air handler, we remove the access panels, clean the blower wheel and housing, clean the evaporator coil with professional coil cleaner, clear the condensate pan and drain line, and reassemble the unit. In St. Augustine South’s slab homes, we also check the pan’s slope and drainage, because standing water there is the root cause of most musty-air complaints. You’ll get photos of the coil and blower before and after.
We schedule St. Augustine South jobs as quickly as our route allows, but we don’t promise same-day service because a proper HVAC cleaning takes time and should never be rushed. If your ducts smell musty, call (737) 727-2314 and we’ll get you on the schedule with a live arrival window you can track. The 365-Day Done Right Promise covers the work whether we’re there tomorrow or next week.
Yes, sometimes it isn’t. If your ducts are dry, the coil is clean, and the only issue is a dirty filter, cleaning the ductwork won’t change much. We’ll tell you that before you spend money. In St. Augustine South’s humid slab homes, though, what looks like dust is often mold or microbial growth on a wet coil or in a sagging flex run, and that’s where cleaning actually restores air quality. We’ll show you the camera footage so you can decide with your eyes, not our sales pitch.
