Air Duct Cleaning Company in Charleston, SC
Air duct repair is where most Charleston duct problems actually start. In a city where so much of the housing was built before 1950 on raised pier foundations, duct runs often travel through damp crawlspaces and unconditioned attics, and the subtropical air does the rest. Mold, mildew, and corroded joints show up here as routine findings, not rare ones. We clean ducts with professional Rotobrush and Nikro extraction, we run Abatement Technologies air scrubbers while we work, and we repair what we find rather than handing you a referral slip. Our technicians have up to 15 years of experience. Call (888) 274-9947 for a free estimate.
Why Charleston Homes Are Different
Charleston sits on a humid subtropical coastal plain, and that one fact shapes nearly every duct job in the city. Air conditioners run almost year round, so condensation forms inside ductwork more often than it does inland. Salt-laden coastal air speeds metal corrosion. The result is a market where duct problems are usually moisture problems wearing a dust costume.
The building stock compounds it. Much of the peninsula is pre-1950 single-family housing and Charleston single houses with raised foundations and exposed floor joists. Ducts there often run through unconditioned crawlspaces or attics, and sometimes through sealed-off piazzas that were never designed as mechanical chases. Newer builds out toward Mount Pleasant and Summerville mix slab-on-grade with pier-and-beam, and those systems behave differently again. On the older peninsula houses, we find supply runs under raised floors where summer condensation and salt air accelerate both mold growth and corrosion of the metal. That pattern is far rarer in the newer suburban subdivisions. Hurricane season and coastal flooding add a second layer: post-storm moisture intrusion can leave a duct system damp long after the visible water is gone, which is exactly when biological growth takes hold.

Our Main Charleston Services
Two services come up most often when Charleston homeowners call: cleaning the ducts themselves, and clearing the dryer vent before it becomes a fire hazard. Here’s what each involves locally.
Air Duct Cleaning in Charleston
Cleaning here is contact cleaning with rotating brushes and simultaneous HEPA extraction, not a vacuum waved at a register. On Charleston’s older houses, that means working the crawlspace and attic runs where debris settles and moisture collects, with Abatement Technologies air scrubbers pulling airborne particulate out of the living space while we work. The climate makes this a moisture and indoor-air-quality job as much as a dust job: nearly year-round AC operation means the system is moving air through humid spaces constantly. If you want the full process laid out, see Air Duct Cleaning in Charleston.
Dryer Vent Cleaning in Charleston
Dryer vents in Charleston clog faster than most homeowners expect, and the coastal humidity makes lint mat down into a dense, sticky layer rather than a loose fluff. That’s why a dryer here starts taking two cycles to finish a load. We run the full vent line, including the long or convoluted runs common in older single houses where the dryer sits far from an exterior wall. Lint buildup in a vent is a real fire risk, so this isn’t a task to defer. The full scope is on our Dryer Vent Cleaning in Charleston page.
Air Duct Repair in Charleston
Air duct repair in Charleston solves a problem the local climate creates: ductwork that was never meant to sit in humid, salt-heavy air, running through crawlspaces and attics under pre-1950 houses on raised foundations. When joints separate, seams open, or metal corrodes through, the system pulls crawlspace air into your living space instead of delivering conditioned air where it belongs. That’s the job we do: diagnose the failure, then repair or replace the damaged section. You can read the broader service overview on our Air Duct Repair page.
Ductwork Repair
Signs you need it
You need ductwork repair when rooms don’t hold temperature evenly, when you smell mustiness at a register that isn’t coming from the air handler, or when you can see separated seams, crushed flex runs, or rusted metal in the crawlspace or attic.
What it costs in Charleston
Ductwork repair in Charleston typically runs $250 to $900, with sealed-joint and small-section fixes at the low end and multi-run repairs higher.
How we do it
We inspect the accessible runs, photograph the failure points, seal and rejoin separated sections with mastic and mesh tape, then verify airflow at the registers before we leave.
Air Duct Replacement
Signs you need it
Replacement is the right call when the duct metal has corroded through in multiple places, when flex runs have collapsed beyond repair, or when a section was sized wrong from the start and can’t deliver enough air.
What it costs in Charleston
Air duct replacement in Charleston typically falls between $1,200 and $4,500 depending on how many runs are replaced and whether the work is in a crawlspace or a finished ceiling.
How we do it
We measure and plan the replacement runs, remove the failed sections, install new duct sized to the system, seal every joint, and pressure-check airflow afterward.
What Air Duct Repair Costs in Charleston
These are typical ranges for Charleston work. The written estimate you get before we start sets the final price.
| Item | Typical range in Charleston |
|---|---|
| Ductwork repair (sealing, reconnecting, small section) | $250 – $900 |
| Air duct replacement (per run set) | $1,200 – $4,500 |
| Diagnostic inspection and written scope | Free with estimate |
Do Charleston’s crawlspace ducts need repair more often than attic ducts?
Often, yes. Raised-floor houses on the peninsula run supply ducts through damp crawlspaces, where summer condensation and salt air corrode metal and loosen joints faster than in the drier, hotter attic runs of newer suburban builds. The crawlspace is where we look first.
Can you repair a duct without replacing the whole system?
In most cases, yes. A failed joint, a crushed flex run, or one corroded section can be repaired on its own. We only recommend full replacement when the damage is spread across many runs or the original sizing is wrong.
Brands We Service in Charleston
We work with Rotobrush and Nikro extraction equipment and fit filtration and IAQ components from Honeywell and Aprilaire, so our recommendations match what’s actually in your system. We don’t stock parts on a truck; when a job needs a specific component, we confirm availability and schedule the work around it. See our brands for the equipment and product lines we handle.

What Charleston Customers Say
"Found a disconnected run in the crawlspace while they were in there and told me about it rather than cleaning around it."
- Craig Sutton"Job was done well and the house smells better. There was some dust knocked loose around a couple of the registers that I had to wipe down afterward."
- Jerome Jackson"Quoted per system rather than the bait and switch per vent pricing everybody else in town uses. The number I was told on the phone was the number on the invoice."
