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.

AfterFast, Reliable Air Duct Cleaning Across Charleston
Air duct cleaning in Charleston, WV typically runs $390-$675 for a full residential system, and a proper job takes 3-5 hours with negative-pressure extraction equipment rather than a shop vac. Most Charleston homes we work on were built between 1945 and 1975, which means decades of accumulated dust, coal soot, and industrial particulate have settled into the ductwork. Our Air Duct Cleaning crews know exactly what older Kanawha Valley homes hide inside their runs. Call (806) 606-6902 and we’ll give you a written price before a single panel comes off.
We’re based in Charleston and serve every neighborhood from the West Side to South Hills to Kanawha City. Scheduling is coordinated from our Charleston office, so when you call, you’re talking to someone who knows the difference between a 1950s East End bungalow and a 1990s Edgewood build. That local knowledge matters when you’re deciding what your system actually needs.

Our Air Duct Cleaning Services in Charleston
Residential Duct Cleaning
Charleston homes often run 50-70 year old ductwork, with original mastic joints and sometimes asbestos-backed foil tape that has to be handled carefully. We clean the full system: supply plenum, return plenum, every branch run, and every register. You get before-and-after photos of each run, so you can see what came out of your own ducts, not a stock photo.
Commercial Duct Cleaning
Office buildings along Kanawha Boulevard and retail spaces in downtown Charleston pull in the same Chemical Valley particulates as homes, just at higher volume. We schedule commercial work on nights and weekends where possible, with documented photo records for facilities managers and building owners. Written scope, written price, written warranty.
Supply Duct Cleaning
Supply ducts are what push conditioned air into your rooms. In Charleston’s hillside neighborhoods like South Hills, supply runs often travel through unconditioned crawl spaces where valley humidity accelerates mold growth inside the metal. We use negative-pressure HEPA extraction with agitation tools, so we’re removing what’s stuck to the walls, not just what’s floating loose.
Return Duct Cleaning
Return ducts pull air back toward your furnace or air handler, and in homes between Charleston and Institute, that means return air cycling Chemical Valley emissions through the system continuously. The fine, oily residue we see in return runs near the river corridor does not respond to a standard blower-and-brush pass. Source removal with agitation is what actually gets it out.

If your HVAC system needs a repair we wouldn’t do without documenting, we’ll tell you in plain language what the camera showed and what it costs to put right.
Common Air Duct Cleaning Problems We See in Charleston Homes
- Mold in crawl space duct runs. The Kanawha and Elk River valleys hold humidity all summer, and hillside homes in neighborhoods like South Hills often run supply lines through unconditioned crawl spaces. That persistent moisture, plus organic dust already in the ducts, colonizes mold inside the runs. Cleaning removes the mold, but sealing joints and addressing crawl space moisture is what keeps it from returning.
- Residual coal soot from converted coal-fired systems. A meaningful share of Charleston’s older homes, especially on the West Side and in Kanawha City, originally burned coal. Even after conversion to gas or heat pumps, the duct walls carry embedded soot that standard blower-and-brush cleaning will not remove. Source removal with aggressive mechanical agitation is what breaks that soot loose.
- Disconnected or crushed duct sections. We regularly find supply runs that pulled apart at the seams decades ago. The camera shows the gap, and sometimes it shows exactly where crawl space air and mold spores have been mixing into the conditioned air stream. Sealing the run with mastic is often the real fix, not just cleaning around the break.
- Oily chemical residue near the river corridor. Homes between Charleston and Institute draw industrial emissions through their return systems. The residue is fine, slightly tacky, and does not resemble household dust. It requires a longer clean cycle and HEPA-filtered negative pressure to remove thoroughly.
Pricing for Air Duct Cleaning in Charleston, WV
Full residential system cleaning in Charleston runs $390-$675 for a typical 1,500-2,500 square foot home with 10-18 duct runs. Supply-only cleaning runs $210-$340, return-only $190-$310.

FAQs - Air Duct Cleaning in Charleston
Charleston sits in a bowl-shaped valley with the Kanawha River industrial corridor running through it, so temperature inversions trap Chemical Valley particulates at ground level more frequently than in flatter, less industrialized parts of the state. Your HVAC system draws those particulates into the return ducts continuously, and they accumulate faster here than in cities without that industrial load. A Charleston duct system degrades faster, so cleaning is a genuine indoor air quality measure, not a routine upsell. Call (806) 606-6902 for a written quote.
Yes. Homes built during the mid-20th century chemical and coal boom, especially in Kanawha City, the West Side, and South Hills, often have 50-70 year old ductwork with original mastic or even asbestos-backed foil tape at the joints. Many were converted from coal-fired systems, leaving embedded soot on duct walls that standard cleaning cannot remove. The job takes longer and requires more aggressive source removal, which is exactly what our equipment is built to do.
Every 2-3 years in most cases, which is more frequent than the 3-5 year interval we recommend for homes on open terrain. The proximity to Chemical Valley emissions means return ducts accumulate a fine, oily residue that domestic HVAC filters cannot catch, and the valley humidity accelerates mold growth in any run that passes through an unconditioned space. Call (806) 606-6902 and we’ll tell you what your camera inspection shows before recommending a schedule.
Cleaning removes the mold that is currently inside the ducts. Stopping the mold from returning requires addressing why it grew in the first place: valley humidity entering through disconnected joints or unsealed access points and condensation on metal in unconditioned crawl spaces. During a full system clean, we document any disconnected sections with the camera and seal what we can with mastic. Our techs will tell you plainly what sealing work remains after the cleaning.
That is most likely Chemical Valley emission residue: fine particulate from the industrial corridor that has cycled through your return system and deposited a slightly tacky film on duct interiors. It is not typical household dust, and it does not respond to blower-and-brush cleaning. Source removal with HEPA-filtered negative pressure and agitation tools is what removes it. It’s a Charleston-specific condition we see regularly in homes along the river corridor, and our photo record documents exactly what was there before and after.
