We’ve worked in Charleston homes long enough to know the difference between a routine cleaning and the kind of restoration this coastal climate demands. Our crews dispatch from the Charlotte office and serve Charleston neighborhoods directly, from the historic peninsula out to West Ashley and North Charleston. That local reach matters when you’re dealing with salt-laden air, year-round humidity, and ductwork that was never designed for modern HVAC loads.

Charleston’s subtropical climate isn’t gentle on metal. Summer dew points regularly climb above 70°F, and hurricane season pushes salt spray deep into crawlspaces and attics. We’ve pulled black biofilm from flex ducts in antebellum homes near Broad Street and replaced corroded galvanized runs in mid-century ranches off Savannah Highway. The problems here are specific, and the fix has to be too.

Why Hollis Air Duct Cleaning Is Charleston’s Preferred Air Duct Cleaning Company

We’ve been part of the Garrison Partners family since 2004, and our Air Duct Cleaning in Charleston reputation is built on showing up inside the window, pricing in writing, and leaving the site clean. That’s The Garrison Standard, and it applies to every job we take on from Mount Pleasant to James Island.

Our technicians are background-checked and uniformed. You know who’s walking into your home before they arrive. We use Rotobrush rotary brush systems and Nikro negative-air machines, the same equipment commercial crews rely on, because Charleston’s humidity-compacted debris demands more than a shop vacuum.

Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues, no waiting until Monday when your ducts are flooding with condensation.

Every job carries our 365-Day Done Right Promise in writing. If the work fails within a year, we return and make it right at no charge, including a free second visit. That guarantee outlasts most competitors’ coverage by months, and we put it on paper before any equipment touches your vents.

Commercial Air Duct Cleaning in Charleston

Commercial Air Duct Cleaning in Charleston addresses the larger-scale buildup that restaurants, medical offices, and retail spaces accumulate from constant HVAC cycling in humid conditions. A typical commercial system in Charleston runs $800 – $2,400 depending on square footage, duct complexity, and whether the property is on the peninsula with limited access or in a newer North Charleston buildout. Most commercial clients schedule during off-hours to avoid disrupting operations.

Kitchen Exhaust and Grease Duct Systems

Charleston’s restaurant scene, from King Street to East Bay, generates heavy grease loading in exhaust ducts that standard cleaning won’t touch. We use negative-air containment and rotary agitation to remove fire-hazard buildup without shutting down your line for multiple days.

Medical and Office Building Protocols

Healthcare facilities near the Medical University of South Carolina require documented antimicrobial fogging and HEPA-level filtration during cleaning. Our crews follow containment protocols that protect occupied spaces, with written verification for facility managers who need compliance records.

Air Duct Cleaning Services in Charleston

Air Duct Cleaning Services in Charleston cover the full range of residential and light commercial systems, from historic single houses with retrofitted flex duct to newer construction with dedicated return plenums. A typical residential full-system cleaning in Charleston costs $350 – $650, with supply-only or return-only runs falling at the lower end and whole-home systems with video inspection at the higher end. Most appointments take 2 – 4 hours and leave no debris behind.

Video Inspection Before and After

We feed a camera through your ductwork before any work starts, so you see the condition yourself. After cleaning, we run it again. That visual proof matters in Charleston, where plaster dust from historic walls and biofilm from humid summers can hide in runs you can’t access from the register.

Antimicrobial Fogging for Mold-Prone Systems

When our technicians find active mold or the black sticky residue common in peninsula homes, we apply an EPA-registered antimicrobial fog that reaches past the register into the trunk line. This isn’t a upsell; it’s a specific response to Charleston’s coastal conditions, and we note it in writing before application.

Trusted Brands We Service in Charleston

Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation, Nikro negative-air machines for containment, and filtration products from Honeywell and Abatement Technologies. We stock Guardsman antimicrobial treatments locally for Charleston jobs, which means faster turnaround when mold or biofilm is involved. These aren’t hardware-store tools. They’re the same units commercial crews use in hospitals and schools, maintained on schedule and operated by technicians trained to The Garrison Code. When a historic home on Tradd Street needs careful handling, or a West Ashley ranch has corroded galvanized duct that requires gentle but thorough cleaning, the right equipment prevents damage while actually removing debris.

Common Air Duct Cleaning Problems We See in Charleston Homes

• Black biofilm in historic district flex duct. Original floor registers in homes near the Battery were retrofitted with flex duct in the 1980s, and the combination of plaster dust, sea air, and 70°F+ dew points creates a sticky residue standard vacuums can’t remove. We encounter this regularly in National Register properties where preservation matters.
• Corroded galvanized ducts in mid-century ranches. West Ashley and North Charleston homes built in the 1950s – 1970s often have original galvanized steel ductwork that rusts through where coastal salt air enters crawlspaces. Cleaning reveals pinholes and separation that explain why rooms won’t heat or cool evenly.
• Post-hurricane crawlspace flooding. After king tides or named storms, ducts in low-lying areas like the Eastside sit in saltwater until the crawlspace dries. Salt accelerates metal corrosion, and we’ve replaced runs that looked intact but crumbled at the first touch of a brush head.
• Mold growth from oversized AC units. Charleston’s humidity leads some homeowners to install larger air conditioners than their ducts can handle, causing short-cycling and condensation inside cool, dark trunk lines. We find active mold in these systems even when the rest of the house looks clean.
