Air Duct Cleaning Company in North Charleston, SC
Air duct repair matters here more than most people expect. North Charleston has a lot of 1950s-through-70s ranch and mill-era homes whose duct systems were cut for a different era of air conditioning, plus tighter new builds near Dorchester Road where flex runs sit in humid attics. Between original leaky joints and Lowcountry moisture, ductwork takes a beating. Sunstone Air Duct Cleaning handles air duct cleaning, dryer vent cleaning, and air duct repair using professional equipment, not improvised tools. One call covers cleaning, repair, and dryer vent safety. Call (855) 683-7582. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday.
Why North Charleston Homes Are Different
Two things set this city apart from the rest of the Lowcountry. First, the housing stock: much of North Charleston is 1950s-to-1980s single-story ranches, brick veneer homes, and mill village houses with original or retrofitted flex duct and sheet-metal trunk lines. Those systems often have leaky joints and undersized returns that trap dust and moisture instead of moving air the way they were meant to. Newer subdivisions off Dorchester Road and around the Palmetto Commerce Parkway area have tighter, more modern ductwork, but humid flex runs still grow mold in the summer.
Second, the setting. North Charleston is a working port and industrial city, and the I-26 and rail corridors send diesel exhaust and fine carbon through the air. Technicians here routinely find black soot and carbon residue inside return ducts and air handlers in homes near the port and rail yards, residue that’s mostly absent in inland suburbs. Add year-round subtropical humidity and near-constant AC in spring and summer, and you have ductwork that condenses, grows microbial film, and develops musty odors. That’s why commercial-style negative-air cleaning and filter upgrades are a standard part of the job here, not an upsell.

Our Main North Charleston Services
Two calls come in more than any other from North Charleston homeowners. Here’s what each one involves in this city.
Air Duct Cleaning in North Charleston
Cleaning ducts here means more than a vacuum pass. We agitate the duct walls with a rotary brush, then pull the loosened debris out through HEPA-filtered extraction so it doesn’t get redistributed into your living space. In this city’s humid climate, that also means addressing condensation and microbial growth rather than just dust, along with the carbon residue that collects in returns near the port and I-26 corridors. Whole-home filtration and air quality accessories are reviewed as part of the visit. We offer Air Duct Cleaning in North Charleston as a full-system job, priced per system rather than per vent, with before-and-after photos of your own ducts so you can see what came out.

Dryer Vent Cleaning in North Charleston
Dryer vent cleaning addresses a leading cause of residential fires, and North Charleston’s humid air makes it worse. Lint picks up moisture, packs against the duct wall, and clings instead of blowing free. Coastal rain and constant AC also raise indoor humidity, which turns a light lint film into a matted block over time. We run the full vent, not just the section you can reach from behind the dryer, and clear the exterior termination so the flap opens fully. Request Dryer Vent Cleaning in North Charleston if your dryer takes longer than one cycle or feels hot to the touch.

Air Duct Repair in North Charleston

Air duct repair in North Charleston usually starts with the same two culprits: age and moisture. Ranches and mill-era homes from the 1950s through the 1980s commonly have original or retrofitted flex duct and sheet-metal trunks with joints that have separated, sagged, or pulled loose at the collar, and humid Lowcountry summers work on that ductwork year after year. When joints leak in a humid house, conditioned air escapes, unconditioned attic air gets pulled in, and condensation forms right where the dust collects. That’s the pattern behind most repair calls here, and fixing it properly is the difference between cleaner air and the same problem coming back. We treat air duct repair as its own discipline, not something to patch on the way out the door.
Repair is where Sunstone does something single-service competitors don’t: we clean ducts and repair ducts, so damaged runs get sealed and rebuilt rather than left behind after the vacuum shuts off.
Ductwork Repair
Signs you need it
You likely need ductwork repair if you notice whistling or rattling at the registers, higher utility bills with no change in use, visible sagging or crushed flex in the attic, or rooms that never seem to cool even when the AC runs steadily.
What it costs in North Charleston
Typical ductwork repair runs about $250 to $750, depending on how many joints, runs, or transitions need sealing or replacement.
How we do it
We pressure-check the system, locate disconnected joints and crushed flex with a camera and airflow readings, seal or reconnect what can be saved, then confirm airflow at each register before we leave.
Air Duct Replacement
Signs you need it
Replacement makes sense when flex runs are torn, rodent-damaged, or saturated with moisture and microbial growth that cleaning can’t fully resolve, or when sheet-metal sections have rusted through in a humid attic.
What it costs in North Charleston
Air duct replacement typically falls in the $1,200 to $3,500 range, scaled to how many runs and trunk sections are being replaced.
How we do it
We map the existing layout, remove damaged sections, install new sealed duct and properly sized returns, then verify static pressure and airflow across the whole system.
What Air Duct Repair Costs in North Charleston
| Item | Typical range in North Charleston |
|---|---|
| Ductwork repair (sealing, reconnecting joints) | $250 – $750 |
| Air duct replacement (per system) | $1,200 – $3,500 |
| Full-system duct cleaning | $350 – $800 |
Can you repair ducts and clean them in the same visit?
Yes. Repair and cleaning work best together, because sealing a leak before the system is clean pushes old debris back through the house. We handle both in one scheduled visit and document the repair points.
How do I know if my North Charleston home needs repair instead of cleaning?
Visible sagging, torn flex, rusted metal, or rooms that won’t cool usually point to repair. Cleaning alone addresses debris and microbial growth. A free estimate pinpoints which one you’re facing before any work begins.

Older ranch and mill-era homes with hard-to-reach attic ductwork also take more time. We agree one flat price per system before work starts, and the written estimate sets the final number.

What North Charleston Customers Say
"My wife's allergies had been bad in this house since we moved in. It's been two months since they did the ducts and it's noticeably better. Not a miracle, but real."
- Devon 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."
- Paul Lawson"Told me straight that our ducts were in decent shape and didn't need doing every year like the mailer companies claim."
- Neil Thompson
