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 Charleston, SC
Air duct cleaning in Charleston runs between $390 and $720 for most single-family homes, depending on square footage and how many vents serve the house. The price we quote is the price you pay because we hand you a written estimate before any tool comes off the truck. Charleston’s humidity, sandy soil, and older housing stock mean ductwork here collects more than dust: humidity blooms into microbial growth inside dark duct runs, and years of beach air leave a fine grit that recirculates through every room. Call (737) 727-2314 and a live person answers, day or night.
Why Charleston Homes Are Different
Charleston’s climate does two things to ductwork that drier cities never see. First, the humidity. From May through September, outdoor air sits above 70 percent relative humidity for weeks at a time, and that moisture finds its way into unconditioned spaces: crawl spaces, attics, and the inside of return ducts. What starts as surface condensation becomes a breeding ground for mold and mildew inside the very channels that move your air. Second, the salt air. Homes east of the Ashley and down toward James Island and Folly Beach get a constant coastal breeze carrying fine salt particulates that settle on evaporator coils and inside supply runs, reducing airflow and letting grime lock in place.
Housing stock matters too. Downtown Charleston and the peninsular neighborhoods like Harleston Village, Ansonborough, and Cannonborough are full of homes built between 1880 and 1940. Many still have original floor registers and duct runs retrofitted decades ago, often with materials that trap debris more aggressively than modern sealed systems. Mount Pleasant, West Ashley, and Summerville have newer construction, but even 15-year-old homes on Johns Island deal with the same coastal humidity and fine sand coming in through every crack. Season matters: we book heaviest in late spring and early fall, when Charleston homeowners finally run their AC constantly and notice dust blooming from every vent.
Our Main Charleston Services
Charleston homeowners call us most about two things: dryer vents that haven’t been cleared since the house was bought, and duct systems that have never been professionally cleaned at all. Here’s how each service works here.
Dryer Vent Cleaning in Charleston
Charleston dryers work hard against humid air, which means lint doesn’t just accumulate; it clumps and sticks to the vent walls. A dryer vent that would stay passable in a dry climate gets congested fast here, especially in laundry rooms on exterior walls where the vent run is short but the air is heavy with salt and moisture. We run professional rotary brushes through the full vent length, then extract everything with a HEPA vacuum so lint doesn’t blow back into the laundry room. If your dryer takes two cycles to dry a normal load, or the outside vent flap barely opens during a cycle, that’s the vent telling you it’s blocked. Full details are on the Dryer Vent Cleaning in Charleston page, including what a typical job costs.
Air Duct Cleaning in Charleston
Whole-home air duct cleaning in Charleston means opening every supply and return register, agitating the inside of every duct run with a Rotobrush rotary brush system, and pulling loosened debris out under negative pressure with a Nikro HEPA vacuum. That last part matters here: negative-pressure extraction means the loosened debris goes straight into the vacuum, not back into your living room. Charleston’s humidity means we also check for moisture staining inside accessible duct runs and flag it when we see it. The Air Duct Cleaning in Charleston page walks through pricing by home size, what the job actually involves, and how long it takes.
HVAC Cleaning in Charleston
Your HVAC system includes the blower fan, the evaporator coil, the drain pan, and the plenum, all of which live in the dark, humid cabinet next to your furnace or air handler. In Charleston, these components collect a sticky film of dust, salt, and microbial growth that standard duct cleaning alone won’t remove. We open the air handler, clean the coil with professional-grade equipment from Abatement Technologies, clear the drain line so condensation doesn’t back up into your ceiling, and check airflow across every component. The HVAC Cleaning in Charleston page covers this service in detail, including what pushes the price up and down.
