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.

Conley isn’t like the bedroom communities to its north. This unincorporated Clayton County area sits in the shadow of rail yards and logistics warehouses, and that industrial character shapes what we find when we open the ducts in homes off Conley Road and Old Dixie Highway. Our technicians know the difference between standard household dust and the black soot that blows in from freight traffic. That local knowledge means we don’t waste time guessing what’s in your system, and we don’t quote you for a suburban home when we’re working on a house that breathes warehouse air.
Why Hollis Air Duct Cleaning Is Conley’s Preferred Air Duct Cleaning Company
We’ve been cleaning ducts across metro Atlanta since 2004, and Conley has become one of our most frequent stops because the conditions here are genuinely different from Forest Park or Morrow. The Garrison Standard requires our technicians to arrive inside the quoted window, price every job in writing before touching equipment, and leave the site clean. In Conley, that standard matters more because many homes have original 1950s – 1970s sheet-metal ductwork in crawlspaces that haven’t been professionally serviced in years.
Our background-checked, uniformed technicians carry Rotobrush rotary brush systems and Nikro negative-air machines, the same equipment used in commercial jobs. Every job gets the 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. Phones are answered by a live person 24 hours a day, 7 days a week, so Conley residents never hit a voicemail loop when scheduling.
Roy Castellanos leads our operation, and our Air Duct Cleaning in Conley crews are trained specifically on the challenges of older working-class housing stock and industrial-adjacent air quality. We don’t send suburban specialists to an industrial-zone job.
Air Duct Cleaning Services in Conley
Air Duct Cleaning Services in Conley involve removing built-up debris from your entire forced-air system, including supply ducts, return ducts, and the main trunk lines that connect them. For Conley homes, this typically means addressing decades of accumulation in original galvanized metal ductwork, plus the fine black soot that enters from nearby freight corridors. A typical residential full-system cleaning in Conley runs $280 – $400 for homes up to 2,500 square feet, with larger homes or heavily contaminated systems reaching $450 – $480.
Residential Duct Cleaning
Most Conley homes are older ranches and brick bungalows with sheet-metal ducts in crawlspaces or attics. Our rotary brush system loosens debris while negative-air suction pulls it out of the home entirely, not just deeper into the system. We photograph the interior of your ducts before and after so you see the difference.

Commercial Duct Cleaning
Conley’s warehouse and light-industrial spaces need periodic cleaning too, especially when office areas share HVAC with loading bays or fabrication floors. We scale our Nikro negative-air equipment to the building size and schedule around your operations.

HVAC Duct Cleaning in Conley
HVAC Duct Cleaning in Conley targets the complete heating and cooling pathway, from the air handler through every branch line to your vents. Because Conley’s red clay soil keeps crawlspace ducts damp year-round, and Atlanta-area humidity promotes mold growth in short-cycling systems, we often find biological contamination that standard dust removal won’t address. A typical HVAC duct cleaning with antimicrobial treatment in Conley runs $320 – $480 depending on system size and contamination level.
Supply and Return Line Cleaning
Supply ducts push conditioned air to your rooms; return ducts pull it back. In Conley, return ducts near the ground level often contain the heaviest soot loads from truck and rail traffic. We clean both directions separately so nothing circulates from one side to the other.
Video Inspection
Our cameras navigate the tight turns of older Conley ductwork to find collapsed sections, pest entry points, and hidden mold colonies. You see the footage in real time, and we use it to build an accurate quote with no surprises.
Trusted Brands We Service in Conley
Our equipment comes from manufacturers who build for the commercial trade, not the retail shelf. We run Rotobrush rotary brush systems for mechanical agitation, Nikro negative-air machines for debris containment, and stock filtration products from Aprilaire, Abatement Technologies, and Guardsman for Conley homeowners who want upgraded protection after cleaning. These aren’t hardware-store tools. A Rotobrush head can navigate the tight, rusted corners common in 1960s Conley ranch ductwork without damaging already-fragile galvanized steel. Aprilaire media filters trap the fine particulate that blows in from I-285 freight traffic, smaller than what standard fiberglass catches. Because we keep common sizes in stock, Conley customers don’t wait weeks for filtration upgrades.
Common Air Duct Cleaning Problems We See in Conley Homes
- Black soot around supply vents. On the residential streets off Conley Road, we regularly find vents coated with diesel particulate from the nearby rail yard and truck depots. This isn’t ordinary household dust, and it requires commercial-grade extraction to remove completely.
- Musty odors from damp crawlspace ducts. Conley’s red clay soil holds moisture against duct trunks, and Atlanta humidity completes the cycle. We find mold and mildew in galvanized runs that were never properly sealed after the 1970s, when Clayton County lacked the municipal codes that would have required it.
- Pest debris in uninsulated trunk lines. Older Conley homes converted from farmhouses or rentals often have gaps in crawlspace ductwork where rodents enter and nest. Our video inspection finds the entry points so they can be sealed after cleaning.
- Short-cycling systems that never fully dry. In mild spring and fall, Conley HVAC systems frequently turn on and off before completing a full dehumidification cycle. That residual moisture feeds biological growth throughout the duct system.
